FAQ

How do I calculate ROI?

ROI % = (revenue − cost) ÷ cost × 100. For example, spending $100 to make $500 is a 400% ROI. This tool computes it instantly.

What is a good ROI?

Any positive ROI means profit. For paid ads, sellers often aim for 200%+ (3x return) to stay comfortably profitable after fees and time.

Can I use this for product launches?

Yes. Enter total revenue from the launch and your total cost (ads, tools, time valued at a rate) to see if it was worth repeating.
