A bonus bet (also known as a free bet or promotional bet) is a common offer from online bookmakers. Instead of wagering your own money, you're using a bet provided by the bookmaker. The key difference from a regular bet lies in how your return is calculated: you typically only receive the profit from the bet, not your original stake back (as the stake was provided by the bookmaker).
How the Calculator Works:
This calculator helps you estimate your potential profit and total return when using a bonus bet. It accounts for two main scenarios:
Using the full bonus amount: You place the entire bonus bet value on a selection.
Using a portion of the bonus amount (your stake): You decide to wager only a part of the bonus bet value.
The Math Behind It:
The calculation depends on the odds format. We handle decimal odds (e.g., 2.50) and fractional odds (e.g., 3/1).
Decimal Odds:
If your odds are in decimal format (e.g., D), the calculation is as follows:
Potential Profit = (Bonus Bet Value * Decimal Odds) – Bonus Bet Value
Total Return = Bonus Bet Value * Decimal Odds
If you specify a stake (S) less than the bonus bet value (B):
Potential Profit = (Stake * Decimal Odds) – Stake
Total Return = Stake * Decimal Odds
Fractional Odds:
If your odds are in fractional format (e.g., N/D, where N is numerator and D is denominator):
Potential Profit = (Bonus Bet Value * (N / D))
Total Return = (Bonus Bet Value * (N / D)) + Bonus Bet Value
If you specify a stake (S) less than the bonus bet value (B):
Potential Profit = (Stake * (N / D))
Total Return = (Stake * (N / D)) + Stake
Example Calculation:
Let's say you have a $50 Bonus Bet and you place it on a selection with Decimal Odds of 3.00.
