What this calculator does

The Campaign ROI calculator forecasts and measures marketing campaign performance: spend against expected conversions, revenue, ROI, and ROAS. Use it to pressure-test a media plan before committing budget, or to report what a campaign actually returned.

The Projection journey sizes the plan; the Impact journey compares delivered results against it, so the next budget conversation starts from evidence.

How it works

Answer a short set of questions — volumes, time, and costs you already track. The calculator runs a pure, versioned formula and presents conservative, moderate, and optimistic scenarios, a receipt-style ledger tracing every figure back to an input, and a multi-year NPV/IRR view. Each report lists its assumptions so reviewers can challenge them line by line. See the methodology for how the models work, or view a complete sample report.

Benchmarks you can defend

Every constant used in-product is cited — the full source list, with caveats, is on the methodology page.

Frequently asked questions

What ROAS should I target?

Context matters more than a universal target, but the citable median blended ROAS for e-commerce is 2.04 (Triple Whale, 2024). The calculator computes your break-even ROAS from margin inputs, which is the number that actually determines whether a campaign made money.

Can I use this for email campaigns?

Yes — enter your send costs and expected conversions like any other channel. If you cite an email ROI benchmark, use the honest version: roughly £32–42 revenue per £1, self-reported by UK marketers (DMA, 2019) — the circulating "$42 per $1" is a currency-mangled copy of that same study.

Is the Campaign ROI calculator free?

Your first calculator is free forever, with unlimited re-runs and one saved report — no card required. You enter your email to view and save results, and upgrading to Pro unlocks all 13 calculators, unlimited reports, exports, and share links.

Can I change the assumptions?

Yes — every assumption is editable before you calculate, and the report records exactly what you used. Industry constants are cited on the methodology page, and the receipt-style ledger traces each figure in the result back to an input.
