MQL to SQL Conversion Rate measures the percentage of Marketing Qualified Leads that become Sales Qualified Leads. It reflects the alignment between marketing and sales, as well as lead quality and lead nurturing effectiveness.
Divide the number of leads that become Sales Qualified Leads by the number of Marketing Qualified Leads, then multiply by 100 to get the percentage.
MQL to SQL Conversion Rate (%) = (Number of SQLs ÷ Number of MQLs) × 100
MQL to SQL Conversion Rate (%) = (Number of SQLs ÷ Number of MQLs) × 100
