Overview

What it is

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.

Why it matters

This metric ensures marketing efforts are generating leads that sales can pursue. A strong MQL to SQL Conversion Rate leads to better pipeline velocity, less wasted spend, and higher return on lead generation investments.

How it is calculated

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.

Good and bad values

A good value

A good MQL to SQL Conversion Rate typically falls between 20–40%, depending on the industry and lead source. Higher rates indicate strong lead qualification and sales-readiness.

A bad value

A conversion rate below 10% may signal poor lead quality, misalignment between teams, or a lack of effective nurturing. This leads to lower sales productivity and wasted marketing efforts.
