Staking calculator
Work out a stake size from your bankroll, your estimate of the true chance and the odds on offer, using the Kelly formula. Fractional Kelly (a quarter or half) is far safer because your probability estimate is never exact.

How it works
- Kelly stake % = (b × p − (1 − p)) ÷ b, where b is decimal odds − 1 and p is your estimated win probability.
- If the result is zero or negative, the price has no edge on your numbers and the sensible stake is nothing.
- This is a maths tool, not advice. Never stake money you cannot afford to lose.
Picks are opinion and analysis, not advice or a guarantee. Only stake what you can afford to lose.
