How do I calculate the value of a sportsbook boost?

Compare the boosted profit to the original profit. The boost value % is the uplift divided by original profit. A +200 boosted to +250 on a $25 stake produces 25% extra profit ($62.50 vs $50).

Are profit boosts +EV?

Only when the boosted price exceeds the no-vig fair price for that market. Boosts on already-mispriced markets are usually +EV; boosts on fair markets often net to roughly break-even after accounting for variance.

Can I hedge a profit boost?

Yes. Toggle hedge mode on and enter the opposite-side price from a different sportsbook. The calculator returns the exact hedge stake that converts the boost into guaranteed cash.

Hedge for Guaranteed Profit

When on, the calculator sizes an opposite-side bet so the payoff is identical on either outcome — turning the boost into guaranteed cash.

Enter original odds, boosted odds, and a stake to see the boost value.

How to Use the Profit Boost Calculator

Enter the Original Odds (the standard market price) and the Boosted Odds (the promo price). Set your Stake — note that most boosts cap stake at $25-$50 per day.

The calculator returns the boosted payout, boosted profit, the boost value as a percentage uplift, and the dollar uplift vs the original line.

Worked example: original +200, boosted to +250, $25 stake. Boosted payout = $87.50, boosted profit = $62.50, original profit = $50, boost value = 25%, uplift = +$12.50.

Toggle Hedge on to compute the opposite-side stake that locks guaranteed profit. This works best when the boost is on a higher-odds line — see the free-bet guide for the broader hedging strategy.

How it works

Sportsbook boosts pay extra profit on a specific line. The calculator quantifies how much the boost is worth vs the original price, and optionally pairs it with a hedge to convert the boost into guaranteed cash.

Find a boost — Most US sportsbooks publish daily "odds boost" markets where a specific line is priced longer than the standard offer.
Enter both prices and your stake — The calculator returns the boost value % and uplift in dollars.
Optionally hedge — Use a different sportsbook to back the opposite side. The calculator sizes the hedge for guaranteed profit.
