How this tool works.
Total cost = COGS + marketplace fees + ads + shipping + other costs. Profit = revenue − total cost. Profit per order = profit / orders. ROI = profit / total cost × 100.
Put it into practice.
Revenue of 1,000 and costs of 700 leave profit of 300. Across 20 orders, profit per order is 15, margin is 30% and ROI on entered costs is 42.86%.
Examples use illustrative amounts in a single currency. Results are estimates, not guaranteed outcomes or marketplace quotations.

What period should the inputs cover?
Use one consistent period for revenue, every cost and order count. Mixing monthly revenue with annual app or operating expenses produces a misleading result.
How is this result calculated?
Total cost = COGS + marketplace fees + ads + shipping + other costs. Profit = revenue − total cost. Profit per order = profit / orders. ROI = profit / total cost × 100.
