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.
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.
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.
Labour = 0.3x25 = $7.50 | Direct = 8+0.5+7.5 = $16.00Labour = 1.5x30 = $45.00 | Direct = 22+6.5+45 = $73.50 | Total = 73.50x1.2 = $88.20Labour = 4x35 = $140.00 | Direct = 45+18+140 = $203.00 | Total = 203x1.3 = $263.904 Sanity check
5 Common errors
| Error | Cause | Consequence | Fix |
|---|---|---|---|
| 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 |
