Free ROI Calculator

Find your return on investment percentage for any campaign or spend.

ROI is one of the most universal business metrics because it works for almost anything: an ad campaign, new equipment, a hire, a software subscription. The key is being consistent about what counts as "cost" (just spend, or spend + overhead) so comparisons across investments stay fair.

Worked Example

Example: You invest $1,000 in a campaign that generates $1,000 in profit (after all costs, not revenue). ROI = $1,000 / $1,000 × 100 = 100% — you doubled your investment.

Formula

ROI % = Net Profit / Cost of Investment × 100

Frequently Asked Questions

Should I use revenue or profit for ROI?
Profit — ROI measures return after costs, not top-line revenue. Using revenue overstates your actual return.
