Free ROI Calculator

See the return on any investment as a clear percentage and dollar profit β€” plus an annualized rate if you enter a time period.

Return on investment (ROI) is the simplest way to compare whether money you put into something β€” an ad campaign, a piece of equipment, a new hire, a marketing channel β€” actually paid off. It expresses your gain as a percentage of what you spent, so a $500 return on a $1,000 investment and a $5,000 return on a $10,000 investment both read as 50% and can be compared at a glance.

Enter the amount you invested and the total amount you got back (or the final value). The calculator shows your net profit and your ROI percentage. If you also enter how long the investment ran in months, it estimates an annualized ROI, which is important because a 20% return in one month is very different from 20% over three years.

The formula is ROI = (return βˆ’ investment) Γ· investment Γ— 100. For marketing specifically, a positive ROI means the campaign made more than it cost; comparing ROI across channels tells you where to put the next dollar. Just be sure you’re counting the full cost, including your time.

StandupCRM ties ad spend to real leads and revenue for repair shops so you can see channel ROI without spreadsheets β€” this tool is the quick, standalone check.
