Question on Calculating Winning Percentages

[qwertvt]

This is may be a ridiculous question, but how do I calculate my winning percentage when there is a push is involved?
For example: If I win 2 games – lose 2 games – and have 1 push
What would be the “winning” percentage? My guess is 50%; however, a push is not truly a “win”.
Any constructive comments would be appreciated.

A tie is not calculated into the percentages. As in baseball how a walk dosent increase your " batting percentage"( winning %) but it does decrease your "average"( ROI average return on your investment.*

If a guy is 2-0 and bets 100 a game his winning % is 100% and his average return per bet is 100

If a guy is 2-0-1 and bets 100 a game his winning % is 100 and his average return is 66
