How to use the profit boost calculator

  1. Enter the boosted stake (usually capped at $25 to $100) and the odds before the boost.
  2. Enter the boost percentage.
  3. Enter the best hedge odds for the opposite outcome at another sportsbook.
  4. Optional: add fair odds for the boosted side from a devigged sharp line to see its unhedged EV.

The math

Boosted decimal odds d′ = 1 + (d − 1) × (1 + boost) Hedge stake H = S × d′ ÷ d₂ Locked profit = S × (d′ − 1) − H

Worked example

A 50% boost on a $50 bet at +250 becomes +375 (decimal 4.75). The best price on the other side is −260.

  • Hedge stake: 50 × 4.75 ÷ 1.385 = $171.53
  • Locked profit: $15.97 either way, about 32% of the boosted stake.

Small, but boosts refresh daily at several books, and they add up. Once the boost is applied, it works like any arbitrage.

Frequently asked questions

Do profit boosts apply to the stake or the winnings?

To the winnings. A 50% profit boost on a $50 bet at +250 raises the profit from $125 to $187.50. The stake comes back either way, so the effective odds become +375.

Which markets work best for boosts?

Longer odds. The boost multiplies profit, so a boost on a +300 bet adds far more than the same boost on a −200 bet. Promo tools like ProfitDuel’s Boost Matcher search for the market where the boosted price beats the best hedge by the widest margin.

Should I hedge a profit boost or let it ride?

Hedge when you want a guaranteed small profit or your bankroll is small. Leave it unhedged when the boosted price is clearly +EV against a sharp fair line and you can handle the swings. Enter fair odds in the calculator to see the unhedged EV.
