How to Use the Character Matchup Win Rate Predictor
In RPGs and strategy games, elemental or trait matchups can swing battles dramatically. This tool calculates the adjusted effective power for both characters and turns it into a win probability percentage, giving you a clear picture of the expected outcome before you fight.
Matchup Bonus Guide
For a neutral matchup, enter 100% for both sides. For an advantageous matchup, enter 110–150%. For a disadvantage, enter 60–90%. Check your game's official documentation for the exact multiplier values.
How the Calculation Works
Adjusted Power = Base Power × (Bonus / 100). Win Rate = My Adjusted Power / (Mine + Enemy) × 100%. When both sides are equal, win rate is exactly 50%.
Frequently Asked Questions
Enter 100% for both sides. The calculator will then return win rates based purely on the ratio of base power stats.
It means both characters' adjusted powers are equal. Actual outcomes also depend on skill, RNG, and player input — so treat this as a probability estimate, not a guarantee.
Multiply all applicable bonuses together to get the final modifier. For example, elemental advantage (120%) × trait bonus (110%) = 132%. Enter 132 as the bonus.
