ROI Calculator — Marketing ROI
Marketing ROI weighs campaign spend against the revenue that spend brought in, which is the same idea expressed by ROAS (return on ad spend) — a 4x ROAS is a 300% marketing ROI once you net out the cost. Enter your ad and program spend as the cost and the attributed revenue as the return to see net contribution and ROI percent. This page pre-fills a single-period campaign scenario, so the holding period is usually left at zero.

Result breakdown
ROI is the net gain divided by the initial cost. Add a holding period to see the annualized (compound-per-year) return.
Comparison arithmetic measured on the initial cost only — it ignores fees, carrying costs, taxes, and reinvested cash flows. An estimate for comparing returns, not financial, investment, or tax advice.
