How to Calculate Lead-to-Customer Ratio
Formula
Lead-to-Customer Rate = (New Customers / Total Leads) x 100
This ratio measures the effectiveness of your entire sales funnel from initial lead capture to closed deal. It combines the impact of lead quality, sales process efficiency, and product-market fit into a single number. Tracking it by lead source reveals which channels produce the best-converting leads.
