Profit boost calculator
A profit boost pays more than the usual winnings: a 50% boost on +100 pays +150. Enter the stake, the odds before the boost, the boost and the other side's odds to see the boosted price and the hedge that locks the result.
The boost formula
boosted decimal odds = 1 + (decimal odds − 1) × (1 + boost)
The boost multiplies the winnings, not the stake. A 25% boost on -110 (decimal 1.909) gives 1 + 0.909 × 1.25 = 2.136, about +114.
Worked example: $50 at +100, 50% boost
Boosted odds = 1 + 1.00 × 1.5 = 2.50 (+150). The other side is +105 (2.05) at another book.
Hedge stake = $50 × 2.50 / 2.05 = $60.98. If the boosted bet wins: $125 − $60.98 − $50 = $14.02. If the hedge wins: $60.98 × 2.05 − $60.98 − $50 = $14.02. That's locked profit on a $50 boost.
When a boost is worth taking
A boost is only good if the boosted price beats the fair price. Check it against the no-vig odds: a 30% boost on a market with a 10% margin may be worth little, while a 50% boost on a main line usually is. Max stakes on boosts are often low, so the profit is small but steady.
Questions
How do profit boosts work?
A profit boost increases the winnings of a bet by a percentage. A 50% boost on a bet that would win $100 makes it win $150. The stake is unchanged.
How do you calculate boosted odds?
Take the decimal odds, subtract 1, multiply by (1 + boost), and add 1 back. For +100 and a 50% boost: 1 + 1 x 1.5 = 2.50, or +150.
Should I hedge a profit boost?
Hedging locks part of the boost's extra value whoever wins. If you'd rather keep the full expected value and can handle the swings, betting the boost alone is also +EV when the boosted price beats fair.
