Break-Even Conversion Rate Calculator
Estimate the click-to-conversion rate required for contribution from a conversion to offset the acquisition cost represented by one click.
How to use this calculator
- Enter cost per click, contribution per conversion before click cost; check the units and use values from the same period or scenario.
- Review the result and intermediate values; change one input at a time when comparing scenarios.
- Keep the stated formula and assumptions with any result you share.
Formula and method
Break-even conversion rate (%) = cost per click ÷ contribution per conversion × 100.
- The break-even conversion rate is about 2.66%.
- Use contribution after variable fulfilment costs, not merely the selling price. This excludes refunds, attribution errors, overhead and taxes.
Worked examples
Worked example
A click costs €0.85 and each conversion contributes €32 before advertising cost.
The break-even conversion rate is about 2.66%.
The break-even conversion rate is about 2.66%.
Understanding the result
The break-even conversion rate is about 2.66%.
Use contribution after variable fulfilment costs, not merely the selling price. This excludes refunds, attribution errors, overhead and taxes.
Important notes
Use contribution after variable fulfilment costs, not merely the selling price. This excludes refunds, attribution errors, overhead and taxes.
Use measured inputs and verify that the model matches the situation before making an operational, financial or technical decision.
Frequently asked questions
What if the required conversion rate exceeds 100%?
Then the entered unit economics cannot break even from a single conversion per click under this model.
Does this predict actual ad performance?
No. It is a threshold calculation; actual conversion rate must be measured.
What should I check before relying on this result?
Verify units, input definitions and assumptions against your real data or the relevant product, service or professional guidance.
