Tipster reality check
Statistical test — is your tipster lucky or actually skilled?
A statistical significance test for tipster performance — separates skill from lucky variance.
Why most tipsters fail this test
Anyone can win 55% over 50 bets by pure luck — variance is huge in short samples. A real edge only reveals itself over hundreds or thousands of bets. This calculator runs a binomial significance test on tipster claims: given their win rate, average odds and sample size, what's the probability their results are just random noise? Pair this with our CLV calculator for the most rigorous edge verification, and Break-even calculator to see what win rate is actually needed.
Industry stat: 80% of paid tipsters lose money over 12+ months. Most cherry-pick winning streaks and hide losing periods. Run their public record through this calculator before paying for anything.

Example: 'pro' tipster with 60% on 50 picks
Claimed: 60% win rate, average odds 1.90, sample 50 picks. Breakeven is 52.6%. Probability of hitting 60%+ by pure chance: ~17%. Significance: weak. To prove skill they need 200+ picks. Most tipsters never hit that sample with consistent edge.
When to use
