A bet placed with a Bonus Bet will pay out the winnings minus the bonus bet stake. For example, if you placed a $20 Bonus Bet at odds of $10 your winnings would be $180. Below is a breakdown of how the bonus bet payout is calculated. $20 (Bonus Bet Stake) x $10 (Odds) = $200.
A Bonus Bet is a token of a dollar value that you are able to use to place bets with. The Bonus Bet is not reflective of your account balance, as it is a completely separate balance.
