How to use this calculator
Enter the cost of the investment and the return or gain you expect from it. The calculator estimates ROI so you can compare options using a simple percentage.
What the result means
Treat the result as a planning estimate, not a guaranteed outcome. ROI can change if costs rise, sales fall, timelines stretch, or the return is harder to measure than expected.
Useful next checks
After estimating ROI, compare it with break-even point, conversion rate, churn rate, and the time or labor required to get the return.
