A price boost calculator works out the lay stake and guaranteed profit from enhanced odds offers, where a bookmaker temporarily offers higher-than-normal odds. By laying the boosted selection on an exchange, you lock in profit regardless of the result.
Enter your stake, the boosted odds, the normal exchange lay odds, and your commission rate. The calculator shows your lay stake, liability, and guaranteed profit.
Price Boost: A Worked Example
Setup: Team A boosted from 2.50 to 4.00. Stake: €25. Lay at 2.55, 5% commission.
Lay stake
Lay = (4.00 × 25) ÷ (2.55 − 0.05) = 100 ÷ 2.50 = €40
If Team A wins
Bookmaker: +€75. Exchange: −€62. Net: +€13
If Team A loses
Bookmaker: −€25. Exchange: +€38. Net: +€13
Guaranteed profit: €13 from €25 stake (52% ROI on qualifying stake).
Common Mistakes with Price Boosts
- ✕Using boosted odds as the lay price. The boost is only at the bookmaker. Lay on the exchange at the normal market price.
- ✕Ignoring maximum stake limits. Most price boosts cap stakes at €5-€25. Check the limit before calculating.
- ✕Slow execution. Check exchange liquidity at the current lay price before placing the back bet, then lay immediately.
Frequently Asked Questions

How much profit can I make from a price boost?
Depends on the gap between boosted and exchange odds and the maximum stake. A boost from 2.50 to 4.00 with €25 max stake and exchange lay of 2.55 generates around €13 guaranteed — roughly 50% ROI on the qualifying stake.
Do I need an exchange account for price boosts?
Yes. To guarantee profit from a price boost, you lay the selection on a betting exchange at the normal market price.
