Lead Conversion Rate Calculator
Free lead conversion calculator. Divide closed deals by leads to find conversion rate for sales funnel.
How Lead Conversion Rate Calculator Works
Lead Conversion Rate = (Customers Acquired ÷ Total Leads) × 100. Measures the percentage of leads that ultimately become paying customers. Unlike website conversion rate (visitor → customer), lead conversion rate applies to sales-qualified leads in a B2B funnel. Salesforce benchmarks average 2–5% for B2B; top-performing teams with strong qualification reach 10%+.
B2B Lead Conversion Rate Benchmarks
| Label | Meaning |
|---|---|
| Above 10% | Strong — well-qualified lead generation |
| 5–10% | Good — above B2B average |
| 2–5% | Average across B2B (Salesforce benchmark) |
| Below 2% | Low — review lead quality or sales process |
Frequently Asked Questions
What is lead conversion rate?
Lead conversion rate measures what percentage of your leads become paying customers. Formula: (Customers ÷ Leads) × 100. Unlike MQL-to-SQL rate (which measures marketing handoff quality), lead conversion rate tracks the full journey from first contact to closed deal.
What is a good lead conversion rate?
Salesforce benchmarks B2B lead-to-customer rate at 2–5% on average. High-performing teams with strong lead qualification can reach 10%+.
How is this different from MQL to SQL conversion rate?
Lead-to-customer rate covers the entire funnel. MQL-to-SQL rate only measures the marketing-to-sales handoff. Both matter — a high MQL-to-SQL rate with a low lead-to-customer rate suggests a sales process problem, not a marketing one.
