League of Legends Match Stat Calculator
Enter your post-game numbers to calculate KDA, KP, CS/min, economy, damage share, and an overall impact score.
Tip: If Team Kills or Team Total Damage is unknown, leave them as 0 and percentage metrics will show as N/A.
Why use a LoL stat calculator?
Most players look at one number after a match: KDA. That’s useful, but it never tells the full story. You can have a pretty KDA and still miss team fights, lose side waves, or do low objective pressure. A better review includes combat, farming, economy, and vision together.
This lol stat calculator helps you do exactly that. Instead of guessing whether a game was “good” or “bad,” you can measure your impact with objective stats and compare your trend over time.
What this calculator measures
KDA Ratio
Formula: (Kills + Assists) / Deaths. If you had 0 deaths, the calculator treats it as a “perfect” game and still gives you a readable ratio.
CS per Minute (CSPM)
Formula: CS / Game Minutes. This tracks farming consistency and wave control. For laners and ADC players, this is usually one of the biggest indicators of reliable improvement.
Kill Participation (KP%)
Formula: (Kills + Assists) / Team Kills × 100. High KP means you were active in your team’s successful fights. Very low KP can signal poor rotations or missed skirmishes.
Gold, Damage, and Vision per Minute
Per-minute metrics show pace. Raw totals are misleading because a 40-minute game naturally gives larger numbers than a 25-minute game. Per-minute values normalize performance for cleaner comparisons.
Damage Share
Formula: Your Damage / Team Damage × 100. This helps identify whether you carried damage load or played a lower-output utility game.
Quick benchmark ranges (rough guidelines)
- Top: 6.0+ CSPM, 45%+ KP, controlled deaths.
- Jungle: 55%+ KP, strong objective timing, stable vision.
- Mid: 6.5+ CSPM, 50%+ KP, high map pressure.
- ADC: 7.0+ CSPM, high gold/min, safe teamfight positioning.
- Support: 60%+ KP, high vision score/min, clean engage/disengage decisions.
These ranges are not strict rules. Champion style, elo, and game tempo always matter. Use trends over 10–20 games rather than judging one match in isolation.
How to review games with this calculator
- Enter your match stats immediately after each game.
- Record your key outputs (KDA, KP, CSPM, and impact score).
- Pick one weak area to improve next game (for example, KP or vision/min).
- Repeat for at least 15 ranked games.
- Adjust goals based on role and champion pool.
Common mistakes players make
- Overvaluing KDA: You can play too passively and still have a “good” KDA.
- Ignoring CSPM: Missed farm silently lowers your item spikes.
- Not tracking vision: Lack of wards causes avoidable deaths and lost objectives.
- Judging one game too hard: Focus on patterns, not single outliers.
Final note
The best players combine numbers with replay review. Use this tool as your quick dashboard: spot what slipped, set one correction, and queue with a clear plan. Over time, this process turns “random games” into structured improvement.
