Money Line to Win Percentage Calculator & Conversion Table

Have you ever wondered what the chances of a team winning were based on the money line for the game?  How to convert the odds to probabilities is a key part of understanding money line bets.

First, we have a simple calculator that you can use to plug in any moneyline (American-style odds) and quickly get the win probability it implies, or turn a win chance into its moneyline. We’ve also included a chart below the calculator for reference, and to see how favorites and underdogs compare.

You can also use our odds calculator to convert decimals, probabilities, American money lines, and fractions if you need a more complex tool but for simple money lines this page is the best.

Money Line Calculator (Implied Probability Converter)

Type a moneyline (-150, +200) to see the win chance it implies, or a win chance (60%) to see its moneyline. It also gives the decimal odds and what a $100 bet pays.

The chart below shows how often you need to win at each price just to break even. That is the implied probability of a moneyline: what you risk divided by what comes back. At -150 you risk $150 to get $250 back (your $150 plus $100 profit), so you need to win 60% of those bets. At +150 you risk $100 to get $250 back, so you need 40%.

One thing a single price can’t tell you is the true chance a team wins. A book’s two prices on the same game add up to more than 100% (52.38% plus 52.38% at -110 both ways is 104.76%), and the extra is the book’s margin. So each side’s implied chance runs a little higher than its fair chance. To strip the margin out, use both sides’ prices in the odds calculator.

For example, you would need to win 80% of all of your bets just to break even if you only bet on -400 money line favorites, and more than 80% to turn a profit.
