How this calculator works
ROI helps compare whether an investment, campaign, project, or business initiative generated enough return relative to its cost. ROAS is especially useful for advertising because it compares revenue to spend.
ROI = (return − investment) ÷ investment
ROAS = revenue ÷ ad or campaign cost
ROAS = revenue ÷ ad or campaign cost
ROI uses profit after cost. ROAS uses revenue divided by spend. They are related, but not the same metric.

FAQ
What is ROI?
ROI measures profit relative to the amount invested.
What is a good ROI?
It depends on risk, timeframe, and business model. Higher ROI is generally better.
How is ROI different from ROAS?
ROI subtracts cost first; ROAS compares revenue directly to spend.
Can ROI be negative?
Yes. A negative ROI means the return was lower than the investment.
Should time be considered?
Yes. A 50% ROI in one month is very different from 50% over five years.
