What this calculator does
A win percentage calculator turns a season or head-to-head record into a single comparable figure: what share of games played were won. The plain version is wins divided by wins plus losses, expressed as a percentage, and it is the number quoted for most leagues and competitions around the world.
Ties complicate the plain formula because a tie is neither a win nor a loss. Some sports and leagues simply drop ties from the count and calculate win percentage only from decisive results. Others, following the convention used across most major American sports, count a tie as half a win, splitting the credit between both sides. Neither approach is universally "correct"; they are different conventions for the same underlying record, and this calculator supports both.
The formula
Excluding ties: win% = wins ÷ (wins + losses) × 100. Counting a tie as half a win: win% = (wins + 0.5 × ties) ÷ (wins + losses + ties) × 100. Choose whichever convention matches the sport or league being reported.
| Term | Meaning |
|---|---|
| Wins | Games or matches won outright. |
| Losses | Games or matches lost outright. |
| Ties | Games that ended level, with neither side winning; also called draws. |
| Half-win convention | Treats a tie as worth half a win and half a loss when computing the percentage, the standard approach in American football, hockey standings and similar leagues that report ties. |
The inputs explained
| Field | What to enter |
|---|---|
| Wins | The number of games or matches won. |
| Losses | The number of games or matches lost. |
| Ties (0 if not applicable) | The number of games that ended in a tie or draw; leave at 0 for sports with no ties. |
| How to treat ties | Whether to count ties as half a win, or leave them out of the calculation entirely. |
When to use it
Ranking teams in a ladder or standings table
Win percentage lets you compare teams that have played a different number of games, which raw win counts cannot do fairly.
A season that allows draws
Sports such as soccer or gridiron in some eras allow tied results; picking the half-win or exclude-ties convention should match how the league itself reports the standings.
Comparing a personal head-to-head record
Whether in a casual league, a card game or a video game ranked mode, the same formula turns any win/loss tally into a single percentage for bragging rights or tracking form over time.

Questions
What is the formula for win percentage?
The basic formula is wins ÷ (wins + losses) × 100. When a competition allows ties, some leagues instead use (wins + 0.5 × ties) ÷ (wins + losses + ties) × 100, counting a tie as half a win.
How do you calculate win percentage with ties?
There are two common conventions: exclude ties from both the win count and the total games, or count each tie as half a win and include all games (wins, losses and ties) in the total. Major American sports leagues typically use the half-win version; many other competitions simply exclude ties.
Is a win/loss percentage calculator the same as a batting average or Elo rating?
No. Batting average and Elo rating are specific statistics for particular sports (baseball/cricket hitting, and a rating system based on opponent strength). Win percentage is a simpler, sport-agnostic measure of the plain share of games won.
What counts as a good win percentage?
It depends entirely on the sport, league and level of competition, so there is no single benchmark. Above 50% means winning more often than not; comparing a team or player's own win percentage across seasons is usually more informative than comparing against an arbitrary target.
For rating changes based on a single result against a specific opponent, see the Elo rating calculator. For baseball or cricket batting statistics, see the batting average calculator.
