How this tool works.
Profit = revenue − product costs − fees − advertising − other costs. ROI = profit / investment basis × 100. Investment is a denominator, not an additional expense.
Put it into practice.
Revenue of 1,000 less costs of 700 gives profit of 300. Against an investment basis of 500, ROI is 60%. The 500 is not deducted again.
Examples use illustrative amounts in a single currency. Results are estimates, not guaranteed outcomes or marketplace quotations.

What should I use as the investment basis?
Enter the capital amount you want to evaluate and use it consistently when comparing scenarios. The result displays this basis explicitly; it is not automatically treated as another cost.
