Estimate return on ad spend from your own assumptions. Enter spend and revenue, or derive revenue from conversions and average order value. Optional gross margin, CPC, CPM, and conversion rate unlock break-even ROAS, CPA, and implied traffic. Nothing is sent to Advarde.
Your return on ad spend
All math runs in your browser. Formulas: ROAS = revenue ÷ spend; CPA = spend ÷ conversions; break-even ROAS = 1 ÷ gross margin; profit = contribution − spend when margin is set, otherwise revenue − spend.
What-if
At 3× ROAS with this revenue, spend would be $1,333.33. At that target with this spend, revenue would need to be $3,000.00.
Implied clicks from CPC: 500.
How to use the ROAS calculator
Choose whether you know revenue directly or will multiply conversions by average order value. Add optional gross margin to see contribution profit and break-even ROAS. Optional CPC, CPM, and conversion rate estimate CPA and implied clicks or impressions.
Adjust the what-if target ROAS to see the spend that matches current revenue, or the revenue needed at current spend.
Formulas explained
ROAS equals revenue divided by spend. CPA equals spend divided by conversions when conversions are known (or implied from spend, CPC, and conversion rate). Break-even ROAS equals 1 divided by gross margin as a fraction when margin is provided. Profit equals contribution minus spend when margin is set; otherwise revenue minus spend.
What this calculator does not do
It does not query auction prices, forecast ChatGPT inventory, or claim a benchmark ROAS for the channel. Pair it with a written test plan and complete measurement before treating a number as a spend decision.
Common questions
How is ROAS calculated?
ROAS equals revenue divided by ad spend. Enter revenue directly, or supply conversions and average order value so revenue = conversions × AOV.
What is break-even ROAS?
When you enter gross margin as a percent, break-even ROAS equals 1 divided by that margin as a fraction. Below that ROAS, contribution does not cover media spend under your margin assumption.
Does this use ChatGPT Ads benchmarks?
No. Every input is yours. The tool does not load auction data or publish channel benchmarks.
Are my numbers stored?
No. Calculations run entirely in your browser and are not sent to Advarde.
How is this different from the budget calculator?
The budget calculator estimates outcomes from budget, CPC, and conversion assumptions. The ROAS calculator starts from spend and revenue (or conversions × AOV) to report ROAS, CPA, break-even ROAS, and profit.
