Cost per Qualified Lead Calculator
Cost per qualified lead separates raw lead volume from leads that meet your chosen qualification criteria. This helps compare campaigns when their lead quality differs.
How to use this calculator
- Enter spend, total leads and a measured lead qualification rate from the same campaign cohort.
- Check that all inputs use the same units, period and population scope.
- Change one assumption at a time when comparing scenarios.
Formula used by cost per qualified lead calculator
Qualified leads = leads × qualification rate; cost per qualified lead = campaign spend ÷ qualified leads.
- Qualified leads = leads × qualification rate; cost per qualified lead = campaign spend ÷ qualified leads.
- Qualification criteria should be documented and consistent. If no leads qualify, unit cost is undefined.
- The tool validates inputs and rounds displayed figures for readability; it does not validate assumptions against external records.

A campaign spends 5,000 and produces 400 leads; if 35% qualify, about 140 leads qualify.
5,000 ÷ 140 = 35.71 per qualified lead.
Estimated qualified-lead cost: 35.71 in the currency used for spend.
