The formula, explained
A return of 1,500 against a cost of 1,000 leaves a net return of 500 and simple ROI of 50%. Define return carefully: revenue is different from contribution after fulfilment and product costs.
Example inputs: return before campaign cost 1,500; total campaign cost 1,000. Result: 50 %.
What to check before using the result
This is simple arithmetic, not an investment forecast. It does not account for time, financing or omitted costs. Avoid counting the same cost twice if your return input already deducts campaign spending.
