The spin offers are valued at the stake per spin, which BetMGM doesn’t publish, so that row rests on an assumption the preset explains. Our guide to [casino bonuses](https://safebet.ai/us/online-casinos/casino-bonuses-explained/) walks through the math, and [RTP and house edge explained](https://safebet.ai/us/online-casinos/rtp-and-house-edge/) gives the numbers for each game. ## How the calculator works 1. **Bonus you receive.** For a deposit match, your deposit × the match percentage, up to the cap. For a credit, the credit. For spins, spins × stake × the slot’s RTP (the expected winnings). For a lossback, your net loss × the refund rate, up to the cap. 2. **Wagering required.** The multiple × the bonus, or × deposit plus bonus when the terms say so. For spins, the multiple applies to the winnings. 3. **Turnover on your game.** Wagering ÷ the game’s contribution: a 20% contribution means betting five times as much. 4. **Expected cost.** Turnover × the house edge (100% − RTP). The slot preset uses 96%; Pennsylvania’s online slots paid back 94.9% in 2025. 5. **Net value.** Bonus − cost. Positive means the offer is worth claiming on average; the break-even RTP is the return at which it stops being. Regulated states protect you here: in New Jersey, Pennsylvania and Michigan, casinos must publish the wagering terms by game type, let you cancel a bonus, and can’t cap your winnings once you’ve met the terms. Set a deposit limit before you claim anything, and remember that winnings are taxable (see our [gambling tax guide](https://safebet.ai/us/guides/gambling-taxes/)).

Value ≈ bonus − (required wagering ÷ game contribution) × house edge, the rule of thumb from the Wizard of Odds that our [bonus guide](https://safebet.ai/us/online-casinos/casino-bonuses-explained/) explains. A $100 bonus at 15x on a 96% slot needs $1,500 of play, which costs about $60 on average, so it’s worth about $40. ### What does “bonus only” versus “deposit plus bonus” mean? Which amount the wagering multiple applies to. A $100 match at 15x on the bonus alone means $1,500 of bets; on deposit plus bonus it means $3,000, which on a 96% slot turns a +$40 offer into a −$20 one. Always check which one the terms use. ### Why does the game I play change the value? Two reasons. Low-edge games such as blackjack lose less per dollar wagered, but casinos usually count them at only 10–20% toward the requirement, or set a higher multiple, so you have to bet far more. The calculator applies both the RTP and the contribution of the game you pick. ### How does the calculator value bonus spins? Spins × the stake per spin × the slot’s RTP gives the expected winnings; any wagering on those winnings costs the same as clearing a credit. 100 spins at $0.20 on a 96% slot are worth about $19.20 before wagering. Where a casino doesn’t publish the spin stake, the preset says what we assumed. ### How does a lossback bonus work in the calculator? A lossback refunds part of your net losses in a set period, as credit with its own wagering. The calculator takes the loss you enter, applies the refund rate and cap, then values the credit. Remember it only pays if you’re down, and the play that produced the loss carried the normal house edge. ### Does a positive value mean I will make money? No. It’s an average over many players who finish the wagering with flat bets. Variance can bust you before you clear it, time limits can expire, maximum-bet rules can void the bonus, and winnings are taxable. Set a deposit limit before you claim anything. ## Keep reading [Guide · 5 min **Online casino bonuses explained** A casino bonus is usually restricted money you must wager a set number of times before you can withdraw it. Its real value is roughly the bonus minus the expected loss on that wagering: a $100 bonus with a 15x requirement means $1,500 of play, which costs about $60 on average on a 96% slot — so it's worth about $40, not $100.

Your expected loss is the total you wager multiplied by the house edge, so $1,000 of spins on a 96% RTP slot costs about $40 on average, while $1,000 of 9/6 Jacks or Better video poker played perfectly costs about $4.60.
