ROI / ROAS Calculator

ROI / ROAS Calculator: Blends ROI, ROAS, net profit, and annualized return for any campaign or capital project. It's built around roi, roas, campaign performance, so you can go from a raw question to a checked answer without switching tools.

The math behind it: ROI shows percent gain, ROAS shows revenue per ad/campaign dollar, and the annualized metric normalizes multi-year initiatives. The core relationship is Total spend = Initial spend + Ongoing costs ROI = (Revenue − Spend) ÷ Spend × 100 ROAS = Revenue ÷ Spend CAGR-style annualized return = (Revenue ÷ Spend)^(1/years) − 1, shown above the calculator so you can see exactly how your inputs turn into the result.

To use it well: (1) Enter the upfront spend and any ongoing or maintenance costs that belong to the initiative. (2) Add the revenue (or savings) generated and the elapsed time in years (fractions allowed). (3) Review spend, profit, ROI, ROAS, revenue multiple, and the annualized return. Keep your units consistent as you go, and re-run a case you already know the answer to — it's the fastest way to catch a typo before it throws off a result you're relying on.

Worked example: entering Initial = $12,000, Ongoing = $1,000, Revenue = $19,000, Years = 3 returns ROI ≈ 46%, ROAS ≈ 1.46×, Net profit = $6,000, CAGR ≈ 13.5%. Try swapping in your own numbers next, especially a case you're unsure about, before you use this for something that matters.
