Free Betting Odds Calculator & Odds Converter
This betting odds calculator converts odds instantly between decimal, fractional, and American formats — useful for cricket, football, and any other sport where odds are quoted differently across bookmakers and regions. It also shows implied win probability and potential payout for a given stake.
How Odds Conversion Works
Implied Probability (%) = (1 ÷ Decimal Odds) × 100. American odds convert to decimal as (American ÷ 100) + 1 for positive odds, or (100 ÷ |American|) + 1 for negative odds. Potential payout = Stake × Decimal Odds, and profit = Payout − Stake.
