Odds boost
Odds Boost Calculator
Work out what a percentage profit boost or a boosted price is worth in dollars. The calculator always compares against the same bet without the boost.
Compare with and without the boost
Choose whether the promo is a percentage profit boost or a new, boosted price. The stake itself is never boosted – only the winnings.

Maximum winnings, bonus-bet stakes, wagering requirements and eligible markets come from the sportsbook's terms and are outside this calculation.
How a profit boost is calculated
Profit without boost = stake × (decimal odds − 1)
Profit with boost = profit without boost × (1 + boost %)
Payout with boost = stake + profit with boost
Equivalent decimal odds = 1 + (decimal odds − 1) × (1 + boost %)
Example: +400 (5.00), a $100.00 stake and a 25% profit boost. The profit without the boost is $400.00; with it, $500.00. The payout is $600.00, the same as odds of +500 (6.00). The $100 stake itself is not boosted.
Boosted odds instead of a percentage
Sometimes the promo is shown as a new price, for example +400 boosted to +500. Choose Boosted odds and enter both prices. A new price can also be worse than the regular one – the calculator then shows a negative difference.
The same payout does not mean the same offer. Terms such as maximum winnings, bonus bets or wagering requirements change what the boost is worth to you and are not part of this calculation.
