How to calculate win-loss ratio
The win-loss ratio expresses competitive success as a direct comparison of wins to losses. It is intuitive: a ratio above 1 means you win more than you lose.
It is mathematically tied to win rate, just framed differently. A win rate of 40 percent corresponds to a win-loss ratio of 0.67 to 1, since you win 40 and lose 60 of every 100 closed deals.

- Tied to win rate Two framings
Short answer
Win-loss ratio compares deals won to deals lost. Divide the number of deals won by the number of deals lost in the period. If you won 40 and lost 60, the win-loss ratio is 0.67 to 1. A ratio of 1 means you win as many as you lose. It is closely related to win rate but framed as a direct comparison.
Step by step
Count deals won and lost
Count closed-won and closed-lost deals in the period. Exclude open deals, which have no outcome yet.
Divide won by lost
Win-loss ratio equals deals won divided by deals lost. A result above 1 means more wins than losses.
Convert to or from win rate
Win rate equals wins divided by (wins plus losses). A ratio of 1 is a 50 percent win rate; a ratio of 0.67 is a 40 percent win rate.
Segment by competitor
Break the ratio out by competitor and segment. A poor ratio against one rival points to where you need a battlecard or product answer.
Worked example
In the quarter you won 45 deals and lost 55. Win-loss ratio = 45 / 55 = 0.82 to 1, meaning you lose slightly more than you win.
The equivalent win rate is 45 / (45 plus 55) = 45 percent. If against one specific competitor your ratio is 0.3 to 1 (you lose three for every win), that competitor is where a targeted battlecard or product improvement would pay off most.

Frequently asked questions
What is the win-loss ratio formula?
Deals won divided by deals lost in a period. A ratio above 1 means you win more than you lose. It excludes open deals and is closely related to win rate, framed as a direct comparison of wins to losses.
How does win-loss ratio relate to win rate?
They are two framings of the same data. Win rate is wins over total closed deals; win-loss ratio is wins over losses. A 50 percent win rate is a 1 to 1 ratio; a 40 percent win rate is 0.67 to 1.
Why segment win-loss ratio by competitor?
Because a poor overall ratio often hides that you lose disproportionately to one rival. Segmenting by competitor pinpoints where a battlecard, pricing change, or product answer would most improve your competitive win rate.
