Odds to Encounters/hr = 512:25 (20 as decimal).
Shiny Hunting
Base rate (Gen 6+): 1/4096. Charm + Masuda + chaining: ~1/512. Expect ~12,300 encounters for 95% confidence at base rate.
Worked Example
4096 Odds to 200 Encounters/hr
- a
- 4096
- b
- 200
- Result
- 512:25 (20.48)

Frequently Asked Questions
How is the Pokemon Shiny Odds Calculator computed?
Odds divided by Encounters/hr, 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 Odds:Encounters/hr mean?
It's a comparison: for every Encounters/hr unit, you have a corresponding amount of Odds. 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.
