RUN THE NUMBERS.
KNOW THE PRICE.
Eight practical tools for understanding payouts, probability, parlays, hedges, sportsbook margin and expected value—before the ticket is placed.
Betting Payout Calculator
See potential profit and total return from your stake and American odds.
Odds Calculator
Convert a price into decimal odds, implied probability, profit and return.
Betting Odds Converter
Enter American, decimal or fractional odds and translate the price instantly.
Parlay Calculator
Combine up to 12 American-odds legs and estimate the final price and payout.
Hedge Calculator
Calculate the opposite-side stake that equalizes the net result on a two-outcome market.
Hold & No-Vig Calculator
Measure the overround and remove the vig from a two-way or three-way market.
Moneyline Converter
Translate an American moneyline into decimal, fractional, implied probability and $100 profit.
Odds Value Calculator
Compare your estimated win probability with the sportsbook price. Your probability estimate controls the result.
What the numbers mean
Implied probabilityThe break-even percentage built into one price, before removing vig.
Total returnYour original stake plus profit. Bonus-bet returns may work differently.
Hold / overroundThe amount the market’s combined implied probabilities exceed 100%; not guaranteed realized sportsbook profit.
Expected valueA long-run average based on your probability estimate—not a prediction that one bet will win.
Calculators are educational estimates. Results may differ because of rounding, pushes, dead heats, voids, taxes, bonus-bet rules or sportsbook settlement terms. Hedging can lock in a loss. Verify every ticket before submitting.
