Mathematical Audit

Merch Profit Margin Formula

Profit is calculated per unit and monthly by subtracting all variable costs (production, shipping, platform fees) and fixed costs (design, marketing) from revenue.

Platform Fee Per Unit = Product Price × (Platform Fee % / 100)
Cost Per Unit = Production Cost + Shipping + Platform Fee Per Unit
Profit Per Unit = Product Price − Cost Per Unit
Profit Margin % = (Profit Per Unit / Product Price) × 100
Monthly Net Profit = (Profit Per Unit × Orders) − Design Cost − Marketing Cost
Break-Even Units = Monthly Fixed Costs / Profit Per Unit

Platform fees vary by provider: Shopify charges 2.9% + $0.30 per transaction, Spring/Teespring takes 0% but has higher base costs, and YouTube Merch Shelf integration varies by partner.
