At these odds the bet breaks even when it wins 40.00% of the time. Add your own estimate to see the expected value.
How betting odds work
Three ways of writing the same price. The calculator converts between them as you type.
American (moneyline) odds
A plus sign shows the profit on a 100 stake (+150 wins 150); a minus sign shows the stake needed to win 100 (−200 means bet 200 to win 100). Favourites carry a minus, underdogs a plus.
Decimal odds
The total return per 1 staked, stake included: 2.50 pays 2.50 for every 1. Multiply by your stake for the payout. Evens is 2.00.
Fractional odds
Profit over stake: 6/4 wins 6 for every 4 staked. Add 1 to the fraction for decimal odds (6/4 = 1.5 + 1 = 2.50). Evens is 1/1.
Implied probability
1 ÷ decimal odds: 2.50 implies 40%. The implied chances on every side of a market add up to more than 100%; the excess is the bookmaker's margin — our no-vig calculator removes it.

Questions
How do you calculate a betting payout?
Convert the odds to decimal and multiply by your stake: that is the total payout, stake included. Subtract the stake for the profit. At decimal odds of 2.50, a 10 stake pays 25.00 — 15.00 profit plus the 10 back.
What does +150 mean in betting?
Positive American odds show the profit on a 100 stake: +150 wins 150 for every 100 bet, so a 10 bet returns 25 in total. It is the same price as decimal 2.50 and fractional 6/4, with an implied probability of 40%.
What does -110 mean in betting?
Negative American odds show how much you stake to win 100: at -110 you bet 110 to win 100. A 10 bet returns 19.09 in total. The implied probability is 52.38%.
How do I convert odds to a probability?
Divide 1 by the decimal odds: 1 ÷ 2.50 = 40%. For American odds, a negative line −A gives A ÷ (A + 100), a positive line +B gives 100 ÷ (B + 100). The two sides of a market add up to more than 100% — the extra is the bookmaker’s margin.
What is the payout on 5/1 odds?
Fractional 5/1 pays 5 profit for every 1 staked, plus the stake back: a 10 bet returns 60. That is decimal 6.00 and American +500.
What is a value bet?
A bet whose odds pay more than your own estimate of the chance says they should. If you think a team wins 45% of the time and the odds imply 40%, the expected value is positive. Open "Is it a value bet?" in the calculator to see it and the Kelly stake.
