Winning percentage compares successful results with the total number of completed games or attempts. For example, 18 wins in 30 games gives a 60% winning percentage.
When draws are part of the record, many competitions treat each draw as half a win. This avoids counting a tie as either a full victory or a complete loss. Because league rules can differ, always use the convention required by the sport or competition.
For sales or business opportunities, the Conversion Rate Calculator provides a closely related success-rate calculation. To compare how performance changes between periods, use the Percentage Change Calculator.

What Is a Winning Percentage Calculator?
This calculator measures how frequently a team, player, competitor, or business wins compared with all completed opportunities. It answers questions such as “What percentage of our games did we win?” and “How does this record compare with another record?”
Winning percentage is commonly used in sports standings, season reviews, esports records, school tournaments, sales competitions, and coaching reports.
| Wins | Losses | Ties | Winning Percentage |
|---|---|---|---|
| 12 | 8 | 0 | 60% |
| 15 | 5 | 0 | 75% |
| 8 | 4 | 2 | 64.29% |
| 81 | 81 | 0 | 50% or .500 |
Winning Percentage Formula
A record of 15 wins and 5 losses contains 20 completed games.
How to Calculate Winning Percentage Manually
Record the wins
Start with the number of games, matches, contests, or opportunities won. Example: 15 wins.
Record the losses
Add the number of completed games or contests lost. Example: 5 losses.
Find total games
Add wins and losses: 15 + 5 = 20 completed games.
Divide wins by total games
Calculate 15 ÷ 20 = 0.75.
Convert to a percentage
Multiply 0.75 by 100 to get a 75% winning percentage.
How to Calculate Winning Percentage With Ties
When the record includes ties or draws, the tie-adjusted approach assigns one-half of a win to each tie.
8 wins, 4 losses, and 2 ties
Adjusted wins = 8 + (0.5 × 2) = 9
Total games = 8 + 4 + 2 = 14
The tie-adjusted winning percentage is 64.29%.
Competition rules matter: Some leagues use points systems rather than the half-win method. Use the official scoring rule for the event you are evaluating.
Worked Examples
Basketball team record
A basketball team records 24 wins and 16 losses.
24 ÷ 40 × 100 = 60%
The team won 60% of its completed games.
Baseball season record
A baseball team finishes with 81 wins and 81 losses.
Standings format = .500
Soccer record with draws
A soccer team has 14 wins, 6 losses, and 10 draws.
Total matches = 30
19 ÷ 30 × 100 = 63.33%
Esports match win rate
A player wins 42 matches and loses 18.
Sales contest success rate
A sales team wins 9 of 25 opportunities.
The team converted 36% of the opportunities it competed for.

Winning Percentage vs Win-Loss Record
A record reports the actual number of wins and losses, while winning percentage reports the success rate. The percentage is often more useful when competitors have played different numbers of games.
Actual result count
A 12–8 record shows 12 wins and 8 losses.
Comparable rate
Both 12–8 and 6–4 equal 60%, despite representing different numbers of completed games.
Winning Percentage vs Win Rate
The terms usually describe the same calculation. “Winning percentage” is more common in traditional sports, while “win rate” is frequently used in esports, gaming, sales, and business reporting.
Applications of Winning Percentage
Compare seasons and teams
Review teams, players, coaches, and season records using a consistent success rate.
Rank uneven schedules
Compare teams that may not have completed the same number of games.
Evaluate group play
Summarize round-robin, league, or group-stage performance.
Track competitive results
Monitor ranked matches, event performance, and trends over time.
Measure opportunities won

Add context to analysis
Combine winning percentage with scoring, strength of schedule, and other performance statistics.
Tips for Accurate Winning Percentage Calculations
Common Mistakes When Calculating Winning Percentage
Leaving losses out of the denominator
Total completed games must include losses as well as wins.
Ignoring ties or draws
When draws are part of the record, include them in the total and use the required league method.
Comparing teams only by total wins
A team may have more wins simply because it played more games. Percentage creates a more balanced comparison.
Reading .750 as 750%
A standings value of .750 means 75%, not 750%.
Including unfinished games
Do not count postponed, canceled, or incomplete contests in the total.
Rounding intermediate values too early
Keep full precision during the calculation and round the final result.
