How much pipeline do you actually need?

The short answer

Required pipeline coverage is 1 ÷ your qualified win rate. A 3X coverage ratio assumes a 33% win rate; at 20% you need 5X, at 25% you need 4X.

Coverage ratios get quoted as if they were laws. They're arithmetic. If you close a fraction w of the qualified pipeline that's due in a period, the pipeline you need to make a number is the number divided by w. Coverage is that divided by the number, which leaves 1 ÷ w.

So 3X is a 33% win rate written down without saying so. It's right for a team that wins a third of what it qualifies, and wrong for everyone else, in one direction or the other.

Coverage by win rate

20%5.0X$5M$50M
25%4.0X$4M$40M
30%3.3X$3.3M$33.3M
33%3.0X (3X)$3M$30M
40%2.5X$2.5M$25M
50%2.0X$2M$20M

Three things the ratio quietly assumes

Qualified, not total. The win rate and the pipeline have to measure the same thing. If your win rate is calculated on qualified opportunities, count only qualified pipeline against it. Mixing a qualified win rate with a CRM total overstates coverage every time.

Due in the period. Pipeline that closes next year doesn't cover this year, however real it is.

By value, not by count. If you win 30% of your deals but mostly the small ones, your win rate by value is lower than 30%, and that's the one that matters here.

Worked example

A $6M number, a 20% qualified win rate. Coverage needed is 1 ÷ 0.20 = 5X, so the pipeline needed is $30M. A seller carrying $18M is at 3X, which looks covered, and is $12M short.

Run your own

Pipeline Check runs this with your own number and win rate, and shows the 3X line and yours on one bar.
