Win Percentage Calculator
Written by the percentages.co.uk team. Reviewed for accuracy.
This calculator works out your win percentage from a record of wins, losses and optional draws. It supports both the simple method (wins divided by games played) and the half-win method, which counts each draw as half a win.
How it works
Win percentage expresses what proportion of all games played resulted in a win. It is widely used in football, cricket, darts, esports, and any competitive setting where you need a single number to summarise a record.
The formula
Win % = (Wins / Games played) × 100
Half-win method: Win % = ((Wins + Draws × 0.5) / Games played) × 100
The half-win method is common in American sports and in any format where a draw is considered a partial win. In the simple method, draws are counted as neither wins nor losses, which can make a record with many draws look better than it is.
Why this works: Dividing wins by total games gives a rate between 0 and 1. Multiplying by 100 expresses it as a percentage that most people find easier to interpret than a decimal.
Worked examples
A Sunday league football team wins 12, draws 4, loses 8 over a season. What is their win percentage?
- Total games: 12 + 4 + 8 = 24
- Simple win %: (12 / 24) × 100 = 50%
- Half-win method: (12 + 4 × 0.5) / 24 × 100 = (14 / 24) × 100 = 58.33%
Answer: 50% (simple) or 58.33% (half-win method)
A darts player wins 18 out of 25 legs. What is their win percentage?
- Total games: 25
- Win %: (18 / 25) × 100 = 72%
Answer: 72%
An esports team finishes a tournament 7 wins, 0 draws, 3 losses. What is their win percentage?
- Total games: 10
- Win %: (7 / 10) × 100 = 70%
Answer: 70%
A chess player has 5 wins, 10 draws, 5 losses. What is their win percentage using the half-win method?
- Total games: 20
- Adjusted wins: 5 + (10 × 0.5) = 10
- Win %: (10 / 20) × 100 = 50%
Answer: 50%
A Premier League side has won 22, drawn 5, lost 11 after 38 games. What is their win percentage?
- Total games: 38
- Win %: (22 / 38) × 100 = 57.89%
Answer: 57.89%
When to use this
- Fantasy football leagues: Comparing managers' head-to-head records over multiple seasons.
- Pub quiz teams: Tracking performance across quiz nights where draws occasionally occur when scores are tied.
- Poker hand analysis: Working out how often a given starting hand or strategy results in a win at the table.
- Business pitching: A sales team tracking their bid win rate from submitted proposals to contracts awarded.
Understanding the result
A win percentage of 50% means you win half your games. Above 50% means more wins than losses; below 50% means more losses. A very high win percentage (above 75%) over a large sample is a strong signal of consistent performance.
Small sample sizes can be misleading. A 100% win rate after three games tells you little. A 70% win rate after 100 games is meaningful. Consider the number of games played alongside the percentage itself.

How to do this in Excel
=((A1+(B1*0.5))/(A1+B1+C1))*100
Put wins in A1, draws in B1 and losses in C1. This uses the half-win method. For the simple method (no draws counted), use =(A1/(A1+B1+C1))*100.
How to do this without a calculator
Add up all games played. Divide wins by that total. Multiply by 100. For a quick estimate, if you have 7 wins from 10 games, that is 70%. Scale up proportionally for larger numbers.
Common mistakes
Forgetting to include draws in total games played
Even if you are using the simple method and not counting draws as partial wins, draws still happened and should be included in the denominator (total games).
Comparing win percentages from different sample sizes
A 80% win rate from 5 games is not as meaningful as 80% from 100 games. Always note how many games the percentage is based on.
