# How do I calculate my winnings?

When you add selections to your Bet Card, the potential payout for your bet is calculated and displayed for you automatically. If you want to understand how this calculation is made, here is how it works:

Sports Interaction displays decimal prices for each outcome in an event. This price includes your bet amount. Your winnings are calculated by simply multiplying your bet amount by the displayed odds. This is the amount you will be paid if the bet wins.

For example: Place a \$10 bet at a price of 5.0

Your return would be: \$10 x 5.0 = \$50

On US Sports, the equivalent 'American line' is can also be displayed. With a 'positive' American line, which indicates the underdog, for every 100 cents you bet, you receive the amount displayed plus your bet amount. For example:

Place a \$10 bet at a cents line of +130 (decimal price of 2.3)

Your return would be: (\$10 x 130 cents) + \$10 bet amount = \$23
(= \$10 x 2.3)

With a 'negative' American line, which indicates the favourite, for every 100 cents you wish to win, you need to bet an amount equivalent to the displayed line.

For example: Place a \$12 bet at a cents line of -120 (decimal price of 1.83)

Your return would be: \$10 + \$12 bet amount = \$22 (= \$12 x 1.83)
