What counts as a lead?

Use a consistent lead definition (e.g., demo request, form submission, inbound call) and keep it the same across the time period.

What if my funnel stages differ?

Map your stages to Lead → MQL → SQL → Customer or use the closest equivalents so the ratios stay comparable.

What is a good conversion rate?

Benchmarks vary widely by industry and channel. Focus on improving your baseline and compare within the same source or segment.

Why can overall rate go down while pipeline grows?

Higher top-of-funnel volume can reduce the overall rate while still increasing total customers. Segment before concluding.

Formula

Stage conversion rate = (Next stage ÷ Previous stage) × 100

Rounded to 2 decimals. Use the same time window for each stage.

How to interpret the rates

Focus on the lowest stage rate before optimizing higher stages.
Compare rates by channel or segment to avoid averaging away issues.
Review lead quality and follow-up speed before changing spend.

Quick example

Leads 1,000 → MQL 300 → SQL 120 → Customers 30.

Stage	Count	Rate	Drop-off
Leads	1000	-	-
MQLs	300	30%	700
SQLs	120	40%	180
Customers	30	25%	90
