A dash means a metric is missing one of its inputs. ROAS is revenue divided by ad spend; break-even ROAS is the point where gross profit equals ad spend. Figures are for planning, not financial advice.
About ROAS Calculator.
Solve Every Ad Metric From the Numbers You Already Have
Type in whatever you can pull from your ad dashboard — spend, revenue, impressions, clicks, conversions, average order value — and the ROAS Calculator derives the rest: CPM, CPC, CTR, conversion rate, CPA/CAC, ROAS, break-even ROAS, POAS, and net profit. Every figure is clearly labeled with the formula behind it, so you can see exactly how each number was reached.
It works like a solver, not a rigid form. Leave revenue blank and it infers it from conversions times your order value; leave order value blank and it works it back out from revenue divided by conversions. Any metric that is still missing an input shows a dash and tells you which fields to fill, instead of quietly printing a misleading zero.
Add your gross profit margin and it does the part most calculators skip: your true break-even ROAS (the return where gross profit finally covers ad spend), the maximum CPA you can pay per conversion, and your net profit after ad spend. A plain verdict tells you whether the campaign is actually above or below break-even.
Common Use Cases
- Campaign check: Drop in last week's spend, clicks, and conversions to see your real CPC, CPA, and ROAS in one place.
- Break-even planning: Enter your margin to learn the minimum ROAS and maximum cost-per-conversion a campaign needs to stay profitable.
- Channel comparison: Run the same figures for Google, Meta, and TikTok side by side to see which channel actually returns more per dollar.
- Budget forecasting: Work backward from a target CPA or ROAS to sanity-check a proposed ad budget before you commit spend.
- Client reporting: Copy a clean text summary or download a CSV of every metric to paste into a report or spreadsheet.
- Funnel diagnosis: Compare CTR against conversion rate to tell whether the problem is the ad, the landing page, or the offer.
Because it computes in plain JavaScript and shows the formula for each metric, there is no black box — the ROAS it reports is simply revenue divided by ad spend, and break-even ROAS is one divided by your margin.
Privacy: Every calculation runs entirely in your browser. Your spend, revenue, and performance figures never leave your device, there is no signup, and there is no daily limit. These numbers are for planning only and are not financial advice.
