Lead-to-Customer Rate
Quick definition
Lead-to-customer rate is the percentage of leads that become customers within a defined time frame, calculated as customers won divided by leads.
Formula
Lead-to-Customer Rate = Customers Won ÷ Leads × 100
Formula variables
- Customers Won
- Customers who originated as leads from the group being measured.
- Leads
- The leads in the group, for example all leads created in a given month.
Worked example
- Leads created in the quarter
- 500
- Of those, became customers
- 40
40 ÷ 500 × 100
Result: 8%
Eight in every 100 leads from that quarter became customers. The figures are illustrative.
How definitions differ
- Cohort or period
- A cohort rate follows leads created in a period until they convert or a cut-off is reached. A period rate divides customers won in a period by leads created in the same period, which can include leads from earlier periods. They differ when the sales cycle is long.
How to interpret it
This is the end-to-end result of the lead funnel: how many contacts become customers. It combines lead quality, sales follow-up and the length of the buying cycle.
Break it down by source and stage to see where leads are lost.
When it is useful
- Comparing lead sources on the customers they produce, not only the leads.
- Estimating customers from a forecast number of leads.
- Finding whether marketing or follow-up is the bottleneck when paired with stage rates.
Limitations
- The definition of a lead varies, so rates are not comparable across companies.
- Long sales cycles make recent cohorts look worse than they will end up.
- It does not show deal value.
Common mistakes
- Using a period rate for a long sales cycle without noting the mismatch.
- Mixing lead types with very different intent.
- Ignoring leads that are still open.
