How to use the max CPC calculator
- Enter your average sale value and gross margin.
- Enter your click to sale rate, the share of ad clicks that end up buying. If you only know leads, multiply your click to lead rate by your lead to sale rate.

The max CPC formula
Max CPC = sale value x margin x conversion rate x (1 – profit share). For a ₹15,000 sale with a 50% margin and 0.5% of clicks buying, each click is worth ₹37.50 in gross profit. To keep 30% of that profit, you can pay up to about ₹26 per click.
Conversion rate changes everything
| Click to sale rate | Break-even CPC (₹15,000 sale, 50% margin) |
|---|---|
| 0.25% | ₹18.75 |
| 0.5% | ₹37.50 |
| 1% | ₹75 |
| 2% | ₹150 |
Doubling your conversion rate doubles the CPC you can afford. A faster, clearer landing page lets you outbid competitors and still profit.
Turn it into bids
With manual CPC bidding, use the max CPC as a ceiling. With smart bidding, convert it into a target cost per sale with the target CPA calculator. Write stronger ads with the Google Ads headline generator to raise click-through rate and Quality Score.
