How it works

Work backward from conversions

The conversion goal and expected rate determine required clicks; CPC turns those clicks into budget.

Clicks = conversions ÷ conversion rate · Budget = clicks × CPC

Worked example

$4,000 for 100 conversions

At a 5% conversion rate, 100 conversions require about 2,000 clicks. At $2 CPC, the estimated media budget is $4,000 and implied CPA is $40.

Understand the result

How much advertising budget do you need?

An advertising budget estimate starts with the conversions you need, the share of clicks expected to convert and your average cost per click. Required clicks equal the conversion goal divided by conversion rate. Multiplying those clicks by CPC gives the estimated media budget.

How to use this calculator

  1. Choose a conversion goal, such as leads, purchases or booked consultations.
  2. Enter an expected click-to-conversion rate using comparable campaign data.
  3. Enter average CPC and calculate the implied budget and cost per conversion.

How to interpret your result

Treat the output as a scenario, not a spending guarantee. CPC and conversion rate can shift with audience size, competition, seasonality and landing-page changes. Run conservative and optimistic assumptions before committing a budget; the estimate excludes fees and production costs.

Frequently asked questions

What if I do not have a conversion rate yet?

Use a clearly labelled assumption and test a range. Replace it with observed campaign data once you have enough relevant traffic rather than treating an industry average as your own result.

How do I know whether the planned CPA is affordable?

Compare it with the gross profit from the conversion. For lead generation, use the target cost-per-lead calculator to include close rate and the amount of gross profit available for acquisition.
