Enter your fixed costs and variable costs per garment. The calculator tells you how many pieces you need to sell each month just to cover your costs — and how many more you need to hit a healthy profit margin.

• Contribution Margin — Selling price minus variable cost — your true per-unit profit engine. Calculates automatically.
• Break-Even Units — Exact number of pieces to sell per month to cover all costs. No guessing, no estimating.
• Break-Even Revenue — The naira amount you need to receive each month before you make any profit.
