Garment Cost Calculator – Inputs and Cost per Unit Explained

A practical guide to calculating garment production cost per unit using real factory inputs.

This guide is designed for users who want to use a calculator-style workflow, focusing on how to prepare and structure inputs before using the Production Cost Calculator.

A garment cost calculator estimates the cost required to produce one garment. This value is the foundation for pricing, margin analysis, break-even planning, and minimum order quantity decisions.

In apparel manufacturing, cost per garment depends on five main components: fabric, labor, trims, packaging, and factory overhead.

Key inputs for garment cost calculation

To calculate garment cost using a calculator, you need to define the main production inputs: fabric, labor, trims, packaging, and factory overhead.

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

This formula gives the factory production cost per garment before adding commercial costs such as freight, duties, commissions, or retail margins.

For a more detailed explanation of the formulas and costing logic, see the garment production cost method.

Example: calculator inputs for a basic garment

Suppose you are producing a basic cotton t-shirt in the United States or importing from overseas. You might have the following realistic inputs:

  • Fabric consumption: 1.6 yards per garment
  • Fabric price: $3.20 per yard
  • Labor cost: $2.40 per garment
  • Trims (labels, thread): $0.55
  • Packaging: $0.35
  • Factory overhead: $1.10 per garment
Fabric Cost = 1.6 × 3.20 = 5.12
Total Cost = 5.12 + 2.40 + 0.55 + 0.35 + 1.10
Garment Cost = 9.52 USD

In this example, the estimated production cost is $9.52 per garment.

Main cost components used in the calculator

  • Fabric: usually the largest cost component
  • Labor: sewing, cutting, finishing
  • Trims: labels, zippers, buttons
  • Packaging: polybags, cartons, hangtags
  • Overhead: factory indirect costs

Common input mistakes in garment cost calculation

  • Ignoring fabric waste or marker efficiency
  • Forgetting trims and packaging
  • Underestimating labor cost
  • Not including factory overhead
  • Mixing fixed costs with per-unit costs
