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.

A little more context

Common questions

Where do I get CPC and conversion rate?

Start with recent data from comparable campaigns. For a new account, use researched assumptions and revise them after enough real traffic has arrived. The example figures are illustrative, not industry benchmarks.

Why are forecast conversions sometimes fractional?

They are expected values from a model. A forecast of 12.5 conversions describes an average expectation, not half a real customer.

Does increasing the budget guarantee more sales?

No. Search demand, auction competition, targeting and landing page performance all affect whether you can spend at the assumed efficiency.
