Contribution per Lead Calculator
Estimate expected contribution generated by a lead after accounting for the cost to acquire that lead.
How to use this calculator
- Enter lead-to-sale close rate (%), contribution per sale before acquisition cost, cost per lead; 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
Expected contribution per lead = close rate × contribution per sale − cost per lead, with close rate expressed as a decimal.
- Expected contribution per lead is €7.60 before any other costs.
- This expected-value estimate can hide variation between lead sources and sales. Use measured cohorts and a consistent contribution definition.
Worked examples
Worked example
A 12% close rate, €180 contribution per sale and €14 cost per lead.
Expected contribution per lead is €7.60 before any other costs.
Expected contribution per lead is €7.60 before any other costs.
Understanding the result
Expected contribution per lead is €7.60 before any other costs.
This expected-value estimate can hide variation between lead sources and sales. Use measured cohorts and a consistent contribution definition.
Important notes
This expected-value estimate can hide variation between lead sources and sales. Use measured cohorts and a consistent contribution definition.
Use measured inputs and verify that the model matches the situation before making an operational, financial or technical decision.
Frequently asked questions
What close rate breaks even?
Divide cost per lead by contribution per sale and multiply by 100, assuming contribution per sale is positive.
Does this include staff costs?
Only if staff costs are already included in contribution per sale or lead cost.
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.
