Garment Costing Sheet Example with Formulas and Calculations

 

Garment Costing Sheet Example: Complete Guide with Formulas and Practical Calculation

Introduction

Garment costing is one of the most important activities in the apparel manufacturing industry. Before accepting an order from a buyer, a garment manufacturer must calculate the estimated production cost to determine whether the order will be profitable. Without proper costing, a factory may receive an order at a price that does not cover its actual expenses.

A garment costing sheet is a document used to calculate the total cost of producing a garment. It generally includes fabric cost, trims and accessories, printing or embroidery, washing, cutting, sewing, finishing, packing, overhead expenses, and profit margin.

For example, if a garment factory manufactures a basic cotton T-shirt, the merchandiser must calculate the cost of fabric, rib, sewing thread, labels, polybags, cartons, printing, and other necessary components. After calculating all expenses, the factory can determine the required selling price per piece.

In this article, we will explain garment costing step by step, including a practical garment costing sheet example, important formulas, fabric consumption calculations, overhead expenses, profit margins, and common costing mistakes.

Whether you are a textile engineering student, a garment merchandiser, a production planner, or a professional working in the apparel industry, this guide will help you understand how garment costing works in real factory operations.

What Is a Garment Costing Sheet?

A garment costing sheet is a structured calculation used to estimate the cost of manufacturing one garment or a complete apparel order.

It helps the merchandising and management teams understand how much money is required to produce each item and what selling price should be quoted to the buyer.

A costing sheet is usually prepared during the product development or order negotiation stage. However, it may also be updated when fabric prices, accessories costs, production requirements, or order quantities change.

A garment costing sheet may include the following information:

• Buyer name and style number
• Garment description
• Order quantity
• Fabric consumption and price
• Rib and other fabric components
• Trims and accessories
• Printing or embroidery charges
• Washing charges
• Cutting and sewing costs
• Finishing and packing expenses
• Factory overhead
• Profit margin
• Final FOB price

The exact format depends on the factory, buyer, product type, and costing method.

For example, a basic knitted T-shirt generally has a simpler costing structure than a washed denim jacket or a multi-component sweatshirt. A garment with special printing, embroidery, garment washing, or complicated construction will require additional cost calculations.

Why Is Garment Costing Important?

Garment costing is not simply about adding expenses together. It is an important part of business planning, price negotiation, production management, and profitability analysis.

1. To Determine the Selling Price

A factory must know its production cost before quoting a price to a buyer. If the factory quotes too low, it may lose money even after completing the order.

A proper costing sheet helps the merchandiser calculate a reasonable selling price based on estimated costs and the target profit margin.

2. To Maintain Profitability

The garment industry often operates with tight profit margins. Small mistakes in fabric consumption, fabric prices, or production expenses can significantly affect the final result.

Accurate costing helps management identify unnecessary expenses and maintain the expected profitability of an order.

3. To Support Price Negotiation

Buyers frequently negotiate garment prices. When a buyer requests a price reduction, the merchandiser should understand which costs can be optimized without affecting product quality.

For example, fabric consumption may be improved through better marker efficiency, or packaging costs may be reduced by revising the packing method with buyer approval.

4. To Prepare an Order Budget

A costing sheet helps the factory estimate the financial requirements of an order before production starts.

It supports planning for fabric purchases, accessories procurement, printing, washing, labor, and other manufacturing expenses.

5. To Compare Estimated and Actual Costs

After production, the factory can compare the original costing with actual expenses.

This comparison helps identify whether the order was profitable and which cost components need improvement for future orders.

Main Components of a Garment Costing Sheet

A garment costing sheet contains several cost components. Understanding each component is essential for preparing an accurate calculation.

1. Fabric Cost

Fabric is often one of the largest cost components in garment manufacturing.

The total fabric cost depends on fabric consumption per garment, fabric price per kilogram or meter, fabric construction, GSM, wastage allowance, and the garment's design.

For knitted garments, common fabric types include:

• Single jersey
• Rib fabric
• Pique fabric
• Interlock
• French terry
• Fleece
• Cotton lycra jersey

For example, a 100% cotton single jersey T-shirt may use 180 GSM fabric, while a heavier sweatshirt may require 260 GSM fleece or terry fabric.

The fabric cost calculation should use the correct consumption unit and price unit.

Formula:

Fabric cost per garment = Fabric consumption per garment × Fabric price per unit

If fabric consumption is measured in kilograms, the fabric price should also be expressed per kilogram.

2. Rib Cost

Rib fabric is commonly used in T-shirt neckbands, polo collars, cuffs, and waistbands.

Rib consumption should be calculated separately if its price or construction differs from the main body fabric.

For example, a T-shirt may use 180 GSM single jersey for the body and 220 GSM rib for the neckband. The rib may also contain elastane, making its price different from the body fabric.

Ignoring rib consumption can lead to an inaccurate garment cost.

3. Trims and Accessories Cost

Trims and accessories are the additional materials required to manufacture, identify, and pack a garment.

Common examples include:

• Main label
• Size label
• Care label
• Hangtag
• Sewing thread
• Main label string
• Polybag
• Barcode sticker
• Carton
• Tissue paper
• Neck tape
• Buttons
• Zippers
• Drawcords

Not every garment requires all these items. The merchandiser should check the buyer's tech pack, packaging instructions, and approved sample before preparing the costing sheet.

4. Printing Cost

Printing charges depend on the artwork, print size, number of colors, print locations, printing method, and order quantity.

Common garment printing methods include screen printing, heat transfer, digital printing, and specialty printing.

A simple one-color chest print usually has a different cost from a large multi-color front-and-back design.

For accurate costing, the merchandiser should confirm the print method and obtain the relevant quotation from the printing department or supplier.

5. Embroidery Cost

Embroidery may be required for logos, decorative designs, or brand identification.

Its cost depends on stitch count, embroidery size, number of locations, thread colors, machine requirements, and order quantity.

If a garment includes embroidery, the estimated embroidery cost should be included separately or under the appropriate decoration cost category.

6. Washing Cost

Washing is particularly important for garments that require a special appearance or hand feel.

Examples include enzyme washing, silicone washing, garment dyeing, pigment washing, and various vintage or distressed effects.

The actual process and price depend on the garment type, required effect, chemical consumption, processing time, and washing supplier.

If the buyer requests a washed appearance, the merchandiser must include the expected washing cost in the costing sheet.

7. Cutting, Sewing, and Finishing Cost

Cutting, sewing, and finishing are important manufacturing cost components.

Cutting costs may include fabric spreading, marker preparation, cutting labor, and related processing expenses.

Sewing costs depend on garment construction, operation count, machine requirements, labor cost, production efficiency, and SMV (Standard Minute Value).

Finishing expenses may include thread trimming, measurement checking, ironing, folding, inspection, and packing preparation.

A factory may calculate these costs using an internal cost rate, operation-based costing, or a standard conversion cost per garment.

8. Packing Cost

Packing costs include the materials and labor required to prepare garments for shipment.

These costs may include individual polybags, barcode stickers, hangtags, carton boxes, carton tape, and other buyer-specific packaging materials.

For export orders, packing requirements should be checked carefully because a small change in the buyer's instructions can affect the final cost.

9. Factory Overhead

Factory overhead includes indirect expenses associated with manufacturing.

Examples include factory rent, electricity, administration, maintenance, depreciation, and other shared operating expenses.

Factories use different methods to allocate overhead. Some calculate an overhead amount per garment, while others use a percentage of selected production costs.

The chosen method should be consistent and should avoid counting the same expense twice.

10. Profit Margin

After calculating the expected total cost, the factory determines its target selling price.

Profit can be calculated as a markup on cost or as a margin on selling price. These are different calculations and should not be confused.

Selling price using markup:

Selling price = Total cost × (1 + Markup percentage)

Selling price using target profit margin:

Selling price = Total cost ÷ (1 − Target profit margin)

For example, if the total cost is $3.00 and the factory wants a 20% margin on the selling price:

Selling price = $3.00 ÷ (1 − 0.20)

Selling price = $3.75

The gross profit is $0.75 per garment, which equals 20% of the selling price.

Practical Garment Costing Sheet Example

Now let us prepare a practical costing sheet for a basic 100% cotton knitted T-shirt.

The following figures are illustrative examples for learning purposes. Actual prices will vary depending on the country, supplier, fabric quality, order quantity, buyer requirements, and factory operating conditions.

Garment Details

Particulars	Details
Buyer	ABC Apparel
Style	Basic Crew Neck T-Shirt
Fabric composition	100% Cotton
Fabric type	Single Jersey
Fabric GSM	180 GSM
Order quantity	10,000 pieces
Currency	USD
Costing basis	Per garment

Estimated Costing Sheet

Cost components	Cost per garment (USD)
Body fabric	$1.65
Neck rib	$0.08
Sewing thread	$0.04
Main label	$0.03
Size label	$0.01
Care label	$0.02
Hangtag and string	$0.05
Polybag and barcode sticker	$0.06
Carton allocation	$0.04
Printing	$0.20
Cutting and sewing	$0.40
Finishing and packing labor	$0.10
Washing	$0.00
Factory overhead	$0.15
Total estimated cost	$2.92

In this example, the estimated manufacturing cost is $2.92 per T-shirt.

Washing is shown as zero because this example assumes an unwashed garment. If the buyer requests garment washing, the actual washing quotation should be added.

Similarly, the costing sheet should be adjusted if the garment requires embroidery, special packaging, additional labels, or other processes.

The fabric, rib, and other material costs in this example are assumed values rather than current market quotations.

Step-by-Step Garment Cost Calculation

Let us examine how the individual components can be calculated.

Step 1: Calculate Body Fabric Consumption

Assume the estimated body fabric consumption is 0.30 kg per garment and the fabric price is $5.50 per kg.

Fabric cost per garment:

Fabric cost = 0.30 × $5.50

Fabric cost = $1.65

Therefore, the estimated body fabric cost is $1.65 per garment.

In a real order, fabric consumption should be calculated from the approved pattern, marker efficiency, garment measurements, fabric GSM, and the factory's established consumption method.

The example uses a given consumption value to demonstrate the costing formula.

Step 2: Calculate Rib Cost

Assume rib consumption is 0.015 kg per garment and the rib price is $5.33 per kg.

Rib cost = 0.015 × $5.33

Rib cost ≈ $0.08 per garment

The rib consumption and price should be verified according to the approved neck construction and rib specification.

Step 3: Calculate Sewing Thread Cost

Assume the estimated sewing thread cost is $0.04 per garment.

This value can be based on thread consumption, thread price, machine operations, and the factory's standard consumption records.

Thread consumption should be checked carefully for garments with extensive topstitching or special construction.

Step 4: Calculate Label and Accessory Costs

Suppose the garment requires the following items:

• Main label: $0.03
• Size label: $0.01
• Care label: $0.02
• Hangtag and string: $0.05

Total label and hangtag cost:

$0.03 + $0.01 + $0.02 + $0.05 = $0.11

Therefore, the total estimated cost of these items is $0.11 per garment.

Other accessories, such as polybags, stickers, and cartons, should be calculated separately.

Step 5: Add Printing Charges

Assume the printing supplier quotes $0.20 per garment for the required artwork.

Printing cost = $0.20 per garment

This cost should be confirmed according to the approved print artwork, print size, number of colors, print locations, and order quantity.

If the buyer requests a special print technique, the estimated charge may need to be revised.

Step 6: Add Manufacturing Costs

Assume the estimated cutting and sewing cost is $0.40 per garment, while finishing and packing labor costs $0.10.

Total manufacturing labor and processing cost:

$0.40 + $0.10 = $0.50

These values should be based on the factory's internal cost rate, garment SMV, labor expenses, and production efficiency.

Step 7: Add Factory Overhead

Assume the factory allocates $0.15 per garment for overhead.

This amount may cover a share of indirect expenses such as electricity, rent, administration, maintenance, and depreciation.

The factory should use a consistent overhead allocation method and ensure these expenses are not already included in another cost category.

Step 8: Calculate the Total Cost

The total cost is the sum of all estimated cost components.

Total cost = Body fabric + Rib + Thread + Labels + Accessories + Printing + Cutting and sewing + Finishing and packing + Washing + Overhead

Using the example:

Total cost = $1.65 + $0.08 + $0.04 + $0.03 + $0.01 + $0.02 + $0.05 + $0.06 + $0.04 + $0.20 + $0.40 + $0.10 + $0.00 + $0.15

Total estimated cost = $2.92 per garment

This is the estimated cost before applying the target selling margin and before adding any costs that are not included in the example.

How to Calculate the FOB Price of a Garment

FOB stands for Free on Board. In apparel exporting, an FOB quotation is prepared according to the agreed delivery point and the applicable Incoterms.

The precise costs included in an FOB price depend on the agreed shipping arrangement and the exporter's responsibilities. Therefore, a factory should confirm which expenses are already included in its costing model.

For this example, assume the $2.92 manufacturing cost does not include a separate export-related cost allocation.

Suppose the estimated additional export-related costs are $0.08 per garment.

FOB cost before profit:

$2.92 + $0.08 = $3.00 per garment

Now assume the factory wants a 20% gross margin on the selling price.

FOB selling price = Cost ÷ (1 − Profit margin)

FOB selling price = $3.00 ÷ (1 − 0.20)

FOB selling price = $3.00 ÷ 0.80

Final illustrative FOB price = $3.75 per garment

At this selling price:

• FOB selling price: $3.75
• Estimated total cost: $3.00
• Gross profit: $0.75
• Gross profit margin: 20%

This calculation assumes the $3.00 cost includes all expenses considered in the example. If the factory has other applicable costs, those should be included before determining the selling price.

Remember that a 20% markup is not the same as a 20% profit margin. A 20% markup on $3.00 would produce a selling price of $3.60, not $3.75.

How to Calculate Total Order Value

After determining the selling price per garment, the merchandiser can calculate the estimated order value.

Assume the order quantity is 10,000 pieces and the FOB price is $3.75 per piece.

Total order value = Order quantity × FOB price

Total order value = 10,000 × $3.75

Total order value = $37,500

This figure represents the illustrative FOB order value, not the factory's profit.

Estimated total cost:

10,000 × $3.00 = $30,000

Estimated gross profit:

$37,500 − $30,000 = $7,500

These figures assume all 10,000 pieces are sold at the quoted price and the estimated costs remain unchanged. Actual results may differ due to production variations, rejected garments, price changes, claims, and other expenses.

Important Garment Costing Formulas

Garment merchandisers and textile professionals should understand the following formulas.

1. Fabric Cost

Fabric cost per garment = Fabric consumption per garment × Fabric price per unit

2. Total Material Cost

Total material cost = Fabric cost + Rib cost + Trims cost + Accessories cost

3. Total Manufacturing Cost

Total manufacturing cost = Material cost + Processing cost + Labor cost + Allocated overhead

The precise definition of manufacturing cost depends on the factory's accounting system.

4. Selling Price Using Markup

Selling price = Total cost × (1 + Markup percentage)

5. Selling Price Using Gross Margin

Selling price = Total cost ÷ (1 − Target gross margin)

6. Gross Profit

Gross profit per garment = Selling price per garment − Cost per garment

7. Gross Profit Margin

Gross profit margin (%) = (Gross profit ÷ Selling price) × 100

8. Total Order Value

Total order value = Order quantity × Selling price per garment

9. Total Fabric Requirement

Estimated fabric requirement = Fabric consumption per garment × Order quantity

If fabric consumption already includes the appropriate wastage allowance, additional wastage should not be added again.

10. Fabric Requirement With Wastage

If consumption is measured before wastage:

Fabric requirement = Net fabric requirement ÷ (1 − Wastage rate)

For example, assume the net fabric requirement is 3,000 kg and the expected wastage rate is 5%.

Fabric requirement = 3,000 ÷ (1 − 0.05)

Fabric requirement = 3,000 ÷ 0.95

Fabric requirement ≈ 3,157.89 kg

This formula treats the wastage rate as a percentage of the total fabric input. The factory's standard method should be used consistently.

Factors That Affect Garment Costing

Several factors can change the final cost of a garment, even when the basic style remains similar.

Fabric GSM and Composition

A higher GSM generally means more fabric mass for a comparable fabric area. However, the actual price also depends on fiber composition, yarn count, construction, finishing, and supplier pricing.

A 100% cotton T-shirt and a cotton-polyester T-shirt may have different fabric costs even if their GSM values are similar.

Garment Size and Measurements

Larger garments generally require more fabric than smaller garments. Size ratios and the buyer's size range can therefore influence average fabric consumption.

The merchandiser should use the approved measurement chart and appropriate size breakdown when calculating consumption.

Order Quantity

Order quantity affects fabric purchasing, accessory pricing, printing setup costs, and production efficiency.

A larger order may reduce certain per-piece costs, but the effect depends on supplier minimums, material availability, and production requirements.

Print and Embroidery Requirements

More colors, larger artwork, multiple print locations, and complex embroidery may increase decoration costs.

All print and embroidery requirements should be checked against the buyer's approved artwork and technical documents.

Washing and Special Finishing

Garment washing, special dyeing, distressed effects, and other finishing treatments can significantly affect the cost.

The required appearance, process method, chemical use, and supplier quotation should be confirmed before finalizing the price.

Production Efficiency and SMV

SMV represents the standard time allocated to complete a garment or operation under defined working conditions.

Higher SMV garments generally require more sewing time than simpler garments. Actual labor cost also depends on the factory's labor rate and production efficiency.

Packaging Requirements

Individual packaging, special hangtags, barcode labels, tissue paper, and customized cartons can increase the total cost.

The merchandiser should check whether packaging requirements vary between countries, purchase orders, or delivery destinations.

Exchange Rates and Supplier Prices

For export orders, exchange rates and changes in raw material prices can affect the final financial result.

A costing sheet should identify the currency used for each quotation and follow the company's rules for updating exchange rates.

Common Mistakes in Garment Costing

Even experienced merchandisers can make costing mistakes when information is incomplete or calculations are not checked properly.

1. Using Incorrect Fabric Consumption

Incorrect fabric consumption can create a significant difference between estimated and actual cost.

Always check the approved pattern, marker efficiency, fabric GSM, size range, and wastage allowance.

2. Forgetting Small Accessories

Labels, barcode stickers, hangtags, and packing materials may appear inexpensive individually. However, their combined cost can become significant in a large order.

Review the buyer's packaging instructions and bill of materials before finalizing the costing sheet.

3. Confusing Markup With Profit Margin

Markup is calculated on cost, while profit margin is calculated on selling price.

Using the wrong formula can result in a selling price below the factory's target.

4. Ignoring Special Processes

Printing, embroidery, washing, heat transfer, and special finishing must be included when required.

A costing sheet that excludes these processes may underestimate the actual cost.

5. Double-Counting Expenses

A factory may include sewing labor in its conversion cost and then add the same labor expense separately.

Similarly, overhead may already be included in an internal production rate.

The merchandiser should confirm what each cost category covers to prevent double-counting.

6. Using Outdated Supplier Prices

Fabric and accessory prices can change over time.

Before quoting a new order, verify the latest relevant supplier quotations and internal cost rates.

7. Ignoring Buyer-Specific Requirements

Different buyers may require different labels, packing methods, testing, inspection, or documentation.

A costing sheet should reflect the actual requirements of the particular style and order.

Tips for Preparing an Accurate Garment Costing Sheet

To improve costing accuracy, follow these practical steps:

1. Collect the latest buyer tech pack, measurement chart, artwork, and packaging instructions.
2. Confirm the fabric composition, construction, GSM, color requirements, and finishing process.
3. Calculate fabric and rib consumption using the approved pattern and the factory's standard method.
4. Obtain updated fabric, trims, accessories, printing, embroidery, and washing quotations.
5. Confirm the factory's cutting, sewing, finishing, and overhead cost rates.
6. Check whether wastage is already included in each consumption figure.
7. Separate manufacturing costs from any additional export or delivery costs.
8. Use the correct markup or gross margin formula.
9. Check the total cost, selling price, order value, and currency.
10. Compare estimated costs with actual production results after shipment.

A spreadsheet program such as Microsoft Excel or Google Sheets can make the costing process easier. By using formulas, the merchandiser can update fabric prices, consumption, and order quantities without recalculating every figure manually.

However, the spreadsheet should be checked carefully because an incorrect formula or missing cost component can affect the entire quotation.

What Is the Difference Between a Costing Sheet and a Consumption Sheet?

A garment consumption sheet and a garment costing sheet are related, but they serve different purposes.

A consumption sheet calculates the quantity of materials required to produce a garment or order.

A costing sheet converts those quantities and other expenses into monetary values.

For example, a consumption sheet may show that one T-shirt requires 0.30 kg of body fabric. If the fabric price is $5.50 per kg, the costing sheet calculates the corresponding body fabric cost as $1.65 per garment.

The consumption sheet helps establish material requirements, while the costing sheet helps determine the estimated manufacturing cost and selling price.

Both documents should use consistent specifications and assumptions.

9. Does garment costing include profit?

A costing sheet may show the estimated cost separately from the proposed selling price and profit. The exact layout depends on the factory's costing format. Profit should be calculated after identifying all applicable costs.

10. How can a merchandiser reduce garment cost?

A merchandiser can help optimize cost by improving fabric consumption, reducing avoidable wastage, obtaining competitive supplier quotations, confirming specifications early, and reviewing packaging and production methods. Any changes must maintain buyer requirements, approved quality, and compliance standards.

Conclusion

Garment costing is an essential skill for textile engineers, apparel merchandisers, production planners, and garment factory management. An accurate costing sheet helps a factory estimate production expenses, negotiate prices, plan material purchases, and evaluate profitability.

The basic process involves calculating fabric consumption, determining trims and accessories costs, adding printing or washing charges where applicable, estimating manufacturing expenses, allocating overhead, and calculating the final selling price.

The practical T-shirt costing example in this article demonstrates how individual costs can be combined to estimate the total cost per garment and the proposed FOB price. However, the figures are illustrative, and every factory should use verified supplier quotations, approved consumption data, and its own cost structure.

For garment merchandisers, the most important lesson is simple: accurate costing begins with accurate information. A well-prepared costing sheet can support better price negotiations, reduce unexpected expenses, and help the factory make more informed business decisions.

Keep learning about garment costing, fabric consumption, SMV, production planning, and merchandising to build your technical knowledge and improve your professional skills in the textile and apparel industry.
