MQL to SQL Conversion Rate

What is Marketing Qualified Lead (MQL) to Sales Qualified Lead (SQL) Conversion Rate?

Marketing Qualified Leads, commonly known as MQLs, are individuals who have indicated they’re more interested than other leads, but not quite ready to fully commit. Ideally, you should only allow certain, designated forms to trigger the promotion of a lead to the MQL stage, specifically those that gate bottom of the funnel offers like demo requests, buying guides, and other sales-ready calls to action.

Sales Qualified Leads (SQLs) are individuals that your sales team has accepted as ready for a direct sales follow up. Using this stage will help your sales and marketing teams stay in sync regarding the quality and volume of leads that you are handing over to your sales team.

The sales metric MQL to SQL conversion rate is the percentage of marketing qualified leads that get converted to sales qualified leads. It’s one of the best ways to determine lead quality and an excellent indicator of how well your marketing team is qualifying and screening leads to maintain a high quality pipeline.

How to calculate MQL to SQL Conversion Rate:

(#) of Sales Qualified Leads / (#) of Marketing Qualified Leads = (#) MQL to SQL Conversion Rate

How to calculate MQL SQL Conversion Rate


  1. Understand the efficiency of you sales development reps in terms of converting Marketing Qualified Leads into Sales Qualified Leads for Account Executives to follow-up on.
  2. Understand if there are issues with the quality of leads being passed to your sales team from marketing.


Similar to SQL to Win Conversion Rate, MQL to SQL conversion rates can be skewed by your average sales cycles length. If it spans multiple months, then looking at MQLs created then converted to SQLs within a month won’t tell you an accurate story because there should be no expectation of converting MQLs within a month.

It’s important to look at Average Sales Cycle Length, to understand over what timeframe you should expect an MQL to convert on average and factor that into the KPI calculation. For example, if your average conversion time from MQL to SQL is 3 months, you should take SQLs created in month 3 and divide them by MQLs created in month 1.
