Moneyline Calculator

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 fair market probability that it implies. 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)


The following chart shows how likely a team is to win based on the odds. This is helpful in handicapping because you can see just what percentage of your wagers you need to win at each given money line in order to profit.

The left chart is to be used for favorites, and the right for underdogs.

Win % – Percentage of wins required to show a profit at a given money line.

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 (over 80% to turn a profit).
