A “25% profit boost” sounds like someone has made your bet 25% better. It has changed something useful: what a winning ticket can pay. It has not made your team more likely to win.
The easiest way to judge one is to forget the bright badge for a minute and count the dollars. What is your normal profit? How much extra does the boost add? And what price are you actually getting?
Source checked October 21, 2026, at 8:03 a.m. EDT. All stakes, odds, boost rates and limits below are hypothetical. This is a calculation guide, not a current promotional offer or a betting pick.
Start with profit, not the whole payout
For an ordinary cash bet, profit is what you win beyond your returned stake. Total return includes both.
Imagine a $20 cash bet at +100. A win earns $20 profit and returns your $20 stake, for $40 total. A 25% profit boost adds 25% of the $20 profit: another $5.
You now have $25 profit and $45 total return. You do not multiply the original $40 return by 1.25 and expect $50.
DraftKings describes a profit boost as increasing the potential profit on a qualifying outcome if it wins. The specific offer’s terms control how it applies.
The calculation takes three steps
1. Calculate the normal profit. At positive American odds, multiply the stake by the odds divided by 100. At negative odds, multiply the stake by 100 divided by the odds’ absolute value.
2. Calculate the extra profit. Multiply the normal profit by the boost rate. For 25%, use 0.25.
3. Add the pieces. Boosted profit equals normal profit plus extra profit. For a winning ordinary cash bet, add the returned stake to get the total return.
| Original odds | Normal profit | Extra profit | Total return |
|---|---|---|---|
| -200 | $10.00 | $2.50 | $32.50 |
| +100 | $20.00 | $5.00 | $45.00 |
| +200 | $40.00 | $10.00 | $70.00 |
The percentage is the same in all three rows. The extra dollars are different because the original profit is different. That does not make the longer shot a better bet; it pays more because its price is different, and a larger payout does not establish its chance of winning.
These examples assume no boost cap, no special settlement adjustment and a full win. Displayed odds and payouts may be rounded. Use the accepted ticket’s price and the offer terms for an actual wager.
Compare the final price, not the badge
A boost can improve a price and still leave you with a worse deal than another available price on the same selection.
Suppose one hypothetical sportsbook offers +100 with a 25% profit boost. A $20 win produces $25 profit. That is equivalent to +125 before any rounding or offer restrictions.
Another sportsbook offers the identical selection at an ordinary +130. The same $20 win produces $26 profit. The plain price pays $1 more than the promoted one.
The comparison only works if the bets are actually the same: same player or team, line, period and settlement terms. A full-game hockey moneyline and a regulation-only bet are not interchangeable prices.
Our player-prop comparison guide walks through that problem when the stat threshold changes, too.
Read the limit in dollars
“Maximum stake” and “maximum extra winnings” describe different limits. In a hypothetical offer capped at a $20 stake, increasing the stake does not necessarily increase the portion receiving the boost. In an offer capped at $10 of extra profit, the percentage cannot create unlimited extra winnings.
Look for the eligible markets, minimum odds, stake limit, extra-profit cap and expiry. If it requires several parlay legs, those extra conditions belong in your decision. Adding a selection to unlock a bigger boost also adds another way for the ticket to lose.
DraftKings’ help page says its boost must be applied before the wager is placed, and availability varies by jurisdiction. Treat those as that operator’s rules, not a promise about every sportsbook. A boost that is not attached to the accepted ticket is not part of its price.
The stake is still at risk
On the $20 cash bet at +100, the 25% profit boost improves a win from $20 to $25 profit. A loss still costs the $20 stake. It does not become a $15 loss, a refund or a free bet.
A bonus bet is a different kind of promotion. Do not carry this cash-stake calculation across to promotional credit without checking how that credit settles.
A boost changes the reward side of the deal. Whether the deal is worthwhile also depends on the outcome’s chance of winning. At the hypothetical boosted +125 price, the break-even win rate is about 44.4%, excluding pushes. The promotion does not tell you whether the true chance clears that mark.
That is the useful limit of the arithmetic: it tells you what the offer pays. It cannot tell you who wins.
Keep the decision simple
Calculate normal profit, calculate the extra, then compare the final price with the same bet elsewhere. Keep your stake tied to your existing budget, rather than increasing it just to reach a promotion’s maximum.
If the offer pushes you into a bet you did not want, passing is a complete decision. An expiring token is not a bill you have to pay.
