How to use the lead conversion calculator.

Add the requested inputs

Use the labelled fields in the workspace above. If example values are provided, try them first or replace them with your own.

Calculate and review

Use the main action when needed. Rates divide qualified leads and customers by total leads; spend and revenue are divided by the relevant lead or customer counts.

Try a worked example

From 1,000 leads, 250 qualified leads and 50 customers, the overall lead-to-customer conversion rate is 5%.

Check the assumptions

Use consistent funnel definitions and attribution windows. Lead quality, sales-cycle length and delayed revenue are not captured by the headline rates.
