Basic Betting Calculator Formulae in Excel
- Convert American to Decimal Odds
=IF(A2>0, (A2/100)+1, (100/ABS(A2))+1)
(Assuming A2 contains American odds) - Implied Probability from Decimal Odds
=1/B2
(Assuming B2 contains Decimal odds) - Profit Calculation
=Stake * (Decimal_Odds - 1) - Total Return
=Stake * Decimal_Odds - Kelly Criterion Formula
=((B2 * C2) - (1 - B2)) / C2
(B2 = your win probability, C2 = Decimal odds – 1)
Multiply the result by bankroll for optimal stake.
