Odds To Percentage Calculator
Have you ever wondered what the chances of a team winning was based off of the money line for the game? That’s a key part of understanding money line bets.

We’ve also included a chart below the calculator for reference, and to see how favorites and underdogs compare.
Odds Ratio To Percentage Calculator
Convert stated odds to a decimal value of probability and a percentage value of winning and losing. This calculator will convert 'odds for winning' an event or 'odds against winning' an event into percentage chances of both winning and losing.

For example, a $100 bet at -200 in American odds (1/2 in fractional or 1.50 in decimal) with a 66.67 percent implied probability has the potential to profit $50 should it win (not total return.
What is overround? Overround, also known as the book percentage, is the combined total of priced probability across all outcomes on a single event.

Money Line Calculator (Implied Probability)
Positive odds - 100 divided by (the american odds plus 100), multiplied by 100 to give a percentage e.g. American odds of 150 = (100 / (150 + 100)). 100 = 40%.

What is overround?
Overround, also known as the book percentage, is the combined total of priced probability across all outcomes on a single event. The price of each event in a given market directly correlates to the percentage chance of that event winning. The overround adds all these percentages to give the bettor an idea of the formulation of the market. In a perfect world, these totals would add up to 100%, however in order for bookmakers to make profit on markets, it is not uncommon to see markets in the range of 120% - to 130%, and these are the markets bettors should try and avoid, instead trying to side with markets that closer to 100% and giving less of a margin to the bookmakers. In main markets such as moneyline and spread betting, the overround is typically low compared to prop bets such as to score the first basket because these prop bets have a higher variance so in order for the book to make consistent profit, they make the overround on these markets higher. Furthermore, in parlay bets, overround is compounded making the margins even greater for sportsbooks.
