Basic
What it is & how to use it
A planning calculator to estimate clicks and spend scenarios for Google Ads from a budget and expected CPC — independent of Google software.
How to use the Google Ads Budget Calculator
1) Enter period budget.
2) Enter expected average CPC.
3) Review estimated clicks and related outputs.
4) Adjust until the learning budget and CPA/ROAS targets look realistic.
Intermediate
Formula & worked example
Estimated clicks ≈ Budget ÷ CPC (when CPC > 0).
Worked example: $1,500 budget ÷ $1.20 CPC ≈ 1,250 clicks.
Refine with your conversion rate to size CPA expectations.
Advanced
Interpretation, edge cases & next steps
Budgets that are too small never exit learning.
Advanced: separate brand vs non-brand; scale winners that hit CPA/ROAS; cut or rewrite losers. Cross-check with CPC and ROAS tools.
Not official Google software — planning only.
