Turn any win-loss-tie record into a win percentage, games behind, and the winning run needed to hit a target.
Games behind needs the leader's record; leave both blank if you only want the win percentage.
win percentage
How to use this tool
Type the wins, losses and ties (or draws). Ties count as half a win, which is the standard convention in most league standings.
The headline is (wins + half the ties) ÷ games played, as a percentage. With no ties it is simply wins divided by games.
Under Advanced options, set the percentage you want to reach to see how many straight wins it would take, assuming no losses along the way.
Also under Advanced options, enter the leader's wins and losses to see how many games back this team sits in the standings.
Formula & worked example
A team at 60 wins and 40 losses has a win percentage of 60 ÷ 100 = 60.0%. Against a leader at 70–30, it sits ((70 − 60) + (40 − 30)) ÷ 2 = 10 games behind. Reaching 65% needs ceil((0.65 × 100 − 60) ÷ 0.35) = 15 straight wins.
Limitations — read this before you rely on it
Ties-as-half-a-win is the common convention but not universal: some leagues ignore ties, count them differently, or rank by points instead of percentage. Games behind also assumes both teams have played a comparable schedule; it is a standings snapshot, not a prediction.
Frequently asked questions
Divide wins by games played. If there are ties, each tie counts as half a win: (wins + 0.5 × ties) ÷ total games, times 100 for a percentage.
It measures how far a team trails the leader, combining the win gap and the loss gap and halving the total. A team 10 games behind must gain 10 games on the leader — through its own wins, the leader's losses, or both.
In most standings, yes, as half a win each. A 10-0-10 record is therefore a 75% win percentage, not 50%. Some sports rank by points instead, so check your league's rule.
No. The maximum is 100%, reached only with an unbeaten record and no ties. A team with ties can never reach exactly 100% under the half-win convention.
It depends on the current record, because every added win also adds a game played. The calculator solves (wins + x) ÷ (games + x) = target for x, rounding up to whole wins.
