Cost per Garment Formula – Step-by-Step with Example

Learn how to calculate cost per garment step by step using realistic apparel manufacturing inputs.

This guide focuses on the underlying formula, explaining how each cost component is defined and combined into total production cost.

Cost per garment is the estimated production cost of one finished unit. It is usually calculated before pricing, margin analysis, break-even planning, and MOQ decisions.

The formula combines the main factory cost components: fabric, labor, trims, packaging, and overhead.

Basic cost per garment formula

Cost per Garment = Fabric Cost + Labor Cost + Trims Cost + Packaging Cost + Overhead

This gives the factory production cost per unit. It does not include freight, duties, commissions, marketing costs, taxes, or retail markup.

For the full costing method and detailed formulas, see the garment production cost method.

Fabric cost formula

Fabric Cost = Fabric Consumption × Fabric Price × (1 + (Waste % / 100))

In the imperial system, fabric consumption is usually entered in yards per garment and fabric price in USD per yard.

Labor cost formula

Labor Cost = (Labor Rate per Hour / 60) × Standard Minutes per Garment

This converts hourly labor cost into a per-garment labor cost using standard production minutes.

Example: applying the cost per garment formula

Suppose a garment has the following inputs:

  • Fabric consumption: 1.40 yards per garment
  • Fabric price: $4.00 per yard
  • Waste allowance: 8%
  • Labor rate: $18.00 per hour
  • Standard minutes: 9 minutes per garment
  • Trims cost: $0.65 per garment
  • Packaging cost: $0.40 per garment
  • Factory overhead: 12% of direct cost subtotal
Fabric Cost = 1.40 × 4.00 × (1 + (8 / 100)) = 6.05
Labor Cost = (18.00 / 60) × 9 = 2.70
Subtotal = 6.05 + 2.70 + 0.65 + 0.40 = 9.80
Overhead = 9.80 × (12 / 100) = 1.18
Cost per Garment = 9.80 + 1.18 = 10.98 USD

In this example, the estimated cost per garment is $10.98.

Components included in the cost per garment formula

  • Fabric consumption and fabric price
  • Fabric waste allowance
  • Labor rate and production time
  • Trims and packaging
  • Factory overhead as a percentage or fixed amount

Common mistakes when applying the formula

  • Using fabric price without adding waste allowance
  • Mixing yards, meters, inches, or centimeters incorrectly
  • Using hourly labor rate without converting it to minutes
  • Forgetting trims, packaging, or overhead
  • Adding commercial costs into factory production cost too early
