How to calculate lead to MQL conversion rate
Lead to MQL conversion rate is the first conversion in the funnel, where raw leads are filtered into those worth marketing attention. It reflects lead quality and the tightness of your MQL criteria.
A very high rate can mean your MQL bar is too low, letting weak leads through; a very low rate can mean the bar is too strict or the lead sources are poor. It is a calibration signal.

Short answer
Lead to MQL conversion rate is the share of raw leads that become marketing qualified leads. Divide the number of MQLs by the total number of leads in the period, then multiply by 100. If 300 of 1,000 leads became MQLs, the rate is 30 percent. It measures top-of-funnel quality and how well your scoring separates real interest from noise.
Step by step
Count total leads
Count all leads generated in the period, using a consistent lead definition, as the denominator.
Count MQLs
Count the leads that met your MQL criteria (engagement plus fit) in the same cohort.
Divide MQLs by leads
Lead to MQL conversion rate equals MQLs divided by total leads, times 100.
Calibrate the MQL bar
Check the rate alongside downstream MQL to SQL conversion. If lead to MQL is high but MQL to SQL is low, your MQL bar is too loose.
Worked example
In the month, you generated 2,000 leads. 600 met your MQL threshold. Lead to MQL conversion = 600 / 2,000 = 30 percent.
If those 600 MQLs then convert to SQLs at only 15 percent, the MQL bar is too loose, passing weak leads. Tightening the scoring so fewer, better leads become MQLs would raise MQL to SQL conversion even as lead to MQL falls.
How Ardovo handles it
Ardovo tracks lead to MQL conversion by source alongside downstream MQL to SQL conversion, so you can calibrate the MQL bar. Rook flags sources whose leads rarely qualify, so you stop paying for volume that never advances.
Frequently asked questions
What is the lead to MQL conversion rate formula?
MQLs divided by total leads in the period, times 100. It measures top-of-funnel quality and how well your lead scoring separates genuine interest and fit from noise.
What is a good lead to MQL conversion rate?
Commonly 25 to 40 percent, though it depends heavily on lead source and how strict your MQL criteria are. Read it alongside MQL to SQL conversion to judge whether your MQL bar is calibrated.
What does a very high lead to MQL rate mean?
Often that your MQL bar is too low, letting weak leads through. Check MQL to SQL conversion: if it is low, tightening the MQL criteria so fewer, better leads qualify will improve downstream conversion and sales efficiency.
