Game MMR Percentile
Estimate your percentile rank from MMR/SR distribution.
Your MMR to Avg MMR = 25:21 (1 as decimal).
MMR Percentile
Most competitive games follow a normal distribution: mean MMR ≈ 2000–2500, std dev ≈ 500. Top 10% typically lives at +1.3σ above mean.
Worked Example
2500 Your MMR to 2100 Avg MMR
- a
- 2500
- b
- 2100
- Result
- 25:21 (1.19)
2500 / 2100 = 1.19. Simplified: 25:21.

Frequently Asked Questions
How is the Game MMR Percentile computed?
Your MMR divided by Avg MMR, plus a simplified ratio (e.g., 4:3) using greatest common divisor. Both decimal and ratio forms are useful in different contexts: decimal for math, ratio form for comparisons or recipe scaling.
What does Your MMR:Avg MMR mean?
It's a comparison: for every Avg MMR unit, you have a corresponding amount of Your MMR. Useful when the absolute numbers matter less than the proportion (e.g., reading 8:1 LTV/CAC immediately tells you the unit economics are healthy without needing the dollar amounts).
Why simplify the ratio?
4:3 is more readable than 200:150. The simplified form (using greatest common divisor) preserves the proportion while making it easier to interpret. Common simplified ratios: 16:9 (widescreen), 4:3 (legacy displays), 3:1 (LTV:CAC for SaaS).
When is a ratio more useful than the absolute values?
Comparison across scales. A $1B company and a $1M company can both have a 3:1 LTV:CAC; the ratio reveals comparable unit economics regardless of scale. Use ratios for benchmarking; use absolute numbers for budgeting.
