Garment Costing Calculator

True cost per garment from fabric, trim, labour hours and overhead. Free costing calculator for independent designers, small apparel manufacturers and boutique makers.

🧮
🎯

A wholesale buyer has asked for your price list, and before you quote anything you want a real number for what each piece actually costs to make — not a guess based on last season's spreadsheet.

Costing & Pricing
Direct cost = Fabric + Trim + (Labour hours × rate) Total cost = Direct cost × (1 + Overhead%) Overhead covers rent, equipment, utilities and admin time not captured in direct labour — a common starting estimate is 15-30% of direct costs for a small studio.
Reference: Standard cost-of-goods-sold (COGS) method used across small-batch apparel manufacturing

1 What this calculator does

Calculates the true cost to produce one unit of a garment by combining fabric, trim/notions and labour costs, then applying an overhead percentage to cover indirect business costs. This is the foundation figure every wholesale and retail price should be built from.

2 Formula & professional reasoning

Direct cost = Fabric cost + Trim cost + (Labour hours x Labour rate) Total cost per unit = Direct cost x (1 + Overhead % / 100)

Many small apparel businesses price based on fabric cost alone, which systematically underprices the garment because labour and overhead are just as real a cost as materials. This calculator forces all three direct cost components into the number, then layers on an overhead percentage — a standard COGS (cost of goods sold) approach used in manufacturing generally, adapted for small-batch and made-to-order apparel production. Getting this number right is the single biggest lever on whether a business is actually profitable at the prices it charges.

3 Worked examples

⚠️ Illustrative example only — not clinical or professional instruction.

Basic
Simple cotton t-shirt
Given: Fabric $8.00, trim $0.50, labour 0.3 hrs at $25/hr, no overhead entered
Working: Labour = 0.3x25 = $7.50 | Direct = 8+0.5+7.5 = $16.00
Answer: Total cost: $16.00 per unit
💡 With no overhead applied, this is the bare minimum cost — real pricing should still add overhead before setting a sale price.
Standard
Lined dress with overhead
Given: Fabric $22.00, trim $6.50, labour 1.5 hrs at $30/hr, 20% overhead
Working: Labour = 1.5x30 = $45.00 | Direct = 22+6.5+45 = $73.50 | Total = 73.50x1.2 = $88.20
Answer: Total cost: $88.20 per unit
💡 Labour dominates the cost here — a common finding for detailed garments, which is why hand-finished pieces command higher prices than simple silhouettes.
Advanced
Structured jacket, high overhead studio
Given: Fabric $45.00, trim $18.00, labour 4 hrs at $35/hr, 30% overhead
Working: Labour = 4x35 = $140.00 | Direct = 45+18+140 = $203.00 | Total = 203x1.3 = $263.90
Answer: Total cost: $263.90 per unit
💡 At this cost, keystone (2x) wholesale pricing alone would price the piece at $527.80 retail — worth checking against comparable market pricing before committing to the design.

4 Sanity check

Typical overhead range
15-30% of direct costs is a common range for small/home-based studios; larger operations with more overhead (rent, staff, equipment) often run higher
If overhead feels too low, revisit whether rent, insurance, software and admin time are genuinely accounted for elsewhere
Labour as % of total cost
For garments with meaningful construction time, labour often makes up 40-60% of direct cost — if it's much lower, double-check the hours entered are realistic
Fabric cost sanity check
Fabric cost per unit should roughly match: (fabric price per metre) x (yardage required) — cross-check with the Fabric Yardage Estimator
Comparing to market price
If total cost is close to or above what similar garments retail for elsewhere, the design, fabric choice or production method likely needs revisiting before launch

5 Common errors

ErrorCauseConsequenceFix
Forgetting to include your own labour time Only costing fabric and trim, treating design/sewing time as 'free' because it's the owner doing it Systematically underprices the business and makes it impossible to ever pay yourself a wage from the margin Always cost your own time at a real hourly rate, even in the early stages — you can absorb some as 'sweat equity' consciously, but the number should still exist
Excluding overhead entirely Pricing only on direct fabric+labour+trim cost with 0% overhead Doesn't account for rent, equipment depreciation, software subscriptions, packaging or admin time — margin looks healthier than it really is Add a realistic overhead percentage (commonly 15-30%) even as a placeholder while refining actual overhead costs
Using average fabric cost instead of actual usage Estimating fabric cost from total fabric spend ÷ number of garments made, rather than actual yardage per garment Inaccurate for a product mix with different fabric requirements per style Calculate fabric cost per unit from actual yardage required for that specific garment (see the Fabric Yardage Estimator) x price per metre
Not updating costs when fabric or labour rates change Using a costing figure from a previous season without revisiting input costs Margins erode silently as material and labour costs rise over time Recalculate garment costs each production run or season, especially when fabric suppliers or labour rates change
