How Many MQLs Do You Need to Hit Your ARR Target? The Exact Formula
Why Most MQL Targets Are Wrong
Most marketing teams set MQL targets by taking last year's number and adding a growth rate. That's not planning — it's hope dressed up as a spreadsheet. The correct approach is to start with your revenue goal and work backwards through every stage of the funnel.
Quick answer: MQLs needed = (ARR target ÷ avg deal size) ÷ win rate ÷ SQO-to-close rate ÷ Stage1-to-SQO rate ÷ MQL-to-Stage1 rate
The Reverse-Funnel Formula
Start with your bookings target and divide by conversion rates at each stage:
Won Deals = Bookings Target ÷ Avg Deal Size
SQOs = Won Deals ÷ Win Rate
Stage 1s = SQOs ÷ Stage1-to-SQO Rate
MQLs = Stage 1s ÷ MQL-to-Stage1 Rate
Example: $5M ARR target, $35K avg deal size, 22% win rate, 32% SQO-to-close, 40% MQL-to-Stage1.
- Won deals needed: $5M ÷ $35K = 143
- SQOs needed: 143 ÷ 0.22 = 650
- Stage 1s needed: 650 ÷ 0.32 = 2,031
- MQLs needed: 2,031 ÷ 0.40 = 5,078 MQLs for the year
Why You Need to Split by Channel
A single blended MQL target is almost always wrong. Paid search MQLs, event MQLs, and outbound-sourced leads don't convert at the same rate. A paid search MQL that converts at 18% MQL-to-Stage1 is fundamentally different from an event MQL that converts at 35%.
Run the reverse-funnel calculation separately for each channel. The resulting channel-level MQL targets will be more accurate and will give your marketing team the breakdown they need to actually hit the number.
The Timing Problem Most Teams Miss
Here's what makes this harder than it looks: the MQLs you need to hit Q3 revenue should have been generated in Q1. Your average sales cycle determines how far in advance MQLs need to enter the funnel to close in a given period.
If your average sales cycle is 90 days, an MQL generated in October can't close until January at the earliest. Month-by-month MQL targets that don't account for this timing lag will always produce a funnel that's too thin in the back half of the year.
The fix: offset your MQL targets backwards by your average sales cycle length. If you need 500 MQLs to close in Q4, you need those MQLs in Q2/Q3 — not Q4.
Benchmarks by Funnel Stage
Typical SaaS conversion rates vary significantly by company type and deal size, but here are reasonable starting benchmarks:
- MQL to Stage 1: 20–35% (higher for outbound, lower for inbound at scale)
- Stage 1 to SQO: 30–50%
- SQO to Close: 20–30% for mid-market, 15–25% for enterprise
If your conversion rates are materially below these, closing the gap on conversion efficiency will have more leverage than increasing MQL volume.
Build the Model Automatically
The reverse-funnel calculation above is straightforward but gets complex fast when you add channels, monthly timing distributions, and rep capacity constraints. ARRGuide's Sales Pipeline Planner runs this model automatically — enter your ARR target and conversion rates and it calculates your MQL, Stage 1, SQO, and deal targets by month and channel.
