# How to convert a moneyline to a percentage

Converting a moneyline to a percent helps bettors to understand the percentage chance each fighter is being given to win the bout. Since moneylines are sometimes difficult to understand for newer bettors, percentages will help clear things up a bit.

How to convert to a percent for a favorite

• Amount you need to bet to win \$1 / (Amount you need to bet to win \$1 + \$1) = Favorite’s %
• Example : Chuck Liddell (-300) vs. Keith Jardine (+220). So Chuck is a -300 favorite, this means you would need to bet \$3 to win \$1. If you take this and plug it into the formula, it would look like this… \$3/(\$3 + \$1) = 75%.

How to convert to a percent for an underdog

• 1/(Amount won when wagering \$1 + \$1) = The underdog’s %
• Example : For Keith Jardine (-220) you will win \$2.20 if you bet \$1. If you take this and plug it into the formula, it would look like this 1/(\$2.20 +\$1) = 31.25

Note: The reason the two percentages do not add up is because of the juice that the sportsbook is putting on this bout. This is how sportsbooks make most of their money. They win a little bit from every fight, and every game bet on because of the juice.
