How to use this calculator
Build a range, not a promise
This is a scenario model, not a live traffic forecast. It assumes the full budget can be spent and that CPC and conversion rate stay constant. Try a higher CPC and lower conversion rate to see a more cautious outcome before agreeing a budget.
Translate the plan into an account budget
Google Ads commonly uses an average daily budget and a 30.4-day multiplier for monthly budgeting. The daily figure here is a planning starting point, not a hard daily cap. Actual delivery varies; budget changes and campaign types can affect spending limits. Check the platform budget report.
A worked example
A £3,000 budget at £1.50 CPC gives 2,000 clicks. A 4% conversion rate gives 80 expected conversions at £37.50 each. At £100 revenue per conversion, that is £8,000 revenue and approximately 2.67× ROAS.
