Bet Rollover Calculator
A bonus headline tells you the prize. The rollover tells you the price. A $100 bonus at 8x can mean wagering $800, $1,600 or $2,400 depending on one line in the terms: whether the multiplier applies to the bonus only, the deposit only, or the deposit plus the bonus. The bet rollover calculator below computes the requirement on all three bases side by side, then plans the clearing schedule (bets needed, days needed, whether it fits before the bonus expires) and handles free spins winnings as a separate case.
The worked example used throughout is a $200 deposit with a $100 bonus at an 8x rollover. On the deposit plus bonus basis used in the calculator’s main result, that is $2,400 to wager: 96 bets at $25, over 24 days at 4 bets a day, inside a 30 day expiry with 6 days to spare. Every figure below is the tool’s output for those inputs. Treat a rollover as a cost to schedule, not a gift to chase, and never let a deadline talk you into bigger bets than you planned. If the bets themselves are parlays, price them separately with the bet parlay calculator before you count them toward a requirement.
Gambling involves risk and bonuses are marketing, designed to keep you betting. A rollover is cleared by staking real money repeatedly, and the expected cost is real even when the bonus clears. Never bet money you cannot afford to lose. Help: National Council on Problem Gambling, 1-800-522-4700.
Quick Answer
The rollover formula and the basis trap
The formula is one multiplication. Everything that goes wrong with bonuses goes wrong in choosing what gets multiplied.
| Basis (same offer: $200 deposit, $100 bonus, 8x) | Calculation | You must wager |
|---|---|---|
| Bonus only | $100 x 8 | $800.00 |
| Deposit only | $200 x 8 | $1,600.00 |
| Deposit + bonus | ($200 + $100) x 8 | $2,400.00 |
| Free spins comparison: $60 winnings at 35x | $60 x 35 | $2,100.00 |
One offer, a threefold spread of obligations, and the advertising only ever shows the $100. Two more traps sit behind the basis. Contribution weighting: at many casinos, slots count 100% of each stake toward the requirement while roulette or blackjack may count 10% or nothing, so the $2,400 can quietly become $24,000 of table stakes. This tool counts stakes at face value, so treat its schedule as the best case and adjust with your terms. And minimum odds rules at sportsbooks can void short priced bets entirely. Hedging both sides of an event to grind through the total is not a shortcut either: the arbitrage percentage calculator shows how the margin on both sides usually turns covered betting into a slow, small loss rather than free progress. A staking system does not change any of this: the betting ladder calculator varies stake size by step, but the requirement is a total to reach, not a pattern to follow.
Clearing plan for the worked example
Knowing the total is half the decision. The other half is whether your normal betting fits it inside the expiry window without changing size or frequency, because changing either to beat a clock is how a bonus turns expensive.
Run the same plan against a 14 day expiry and the tool warns instead of reassuring: you would need $171.43 wagered per day, roughly 7 bets a day at $25, nearly double your normal pace. That warning is the most useful output on this page. A requirement that only clears if you bet more often than you intended is not a bonus with a deadline. It is a deadline with a bonus attached. Walking away before depositing costs nothing; walking away after depositing usually forfeits the bonus and its winnings.
Signs an offer is fairly built
- Basis stated in plain words near the offer, not three links deep.
- Multiplier in single digits or low teens on a sportsbook bonus, with a 30 day or longer window.
- Your normal stakes and pace clear it with days to spare, per the plan above.
- Contribution rates and minimum odds listed in the same terms page.
Signs to walk away
- Huge headline bonus paired with a 35x or higher multiplier on deposit plus bonus.
- Expiry of 7 days or less against a four figure requirement.
- Your favourite games contribute 10% or less, multiplying the real staking needed.
- Maximum bet rules while a bonus is active that can void winnings if breached by accident.
What competing calculators miss
The rival tools for this keyword mostly compute one multiplication and stop. Worse, several hard code the basis: at least one widely copied example only ever applies the multiplier to deposit plus bonus and tells users wanting the bonus only answer to fudge the deposit input to zero.
Winning move 1: all three bases, compared in the result itself. The basis is the variable that triples the obligation, so the result block prints the chosen basis and the other two figures ($2,400.00 against $800.00 bonus only) instead of hiding them behind separate runs.
Winning move 2: a clearing plan with an expiry verdict. A requirement figure alone does not tell you whether to accept an offer. Bets needed, days needed at your pace, and a hard warning when the schedule misses the expiry ($171.43 a day needed on a 14 day window in the example above) turn a number into a decision.
Winning move 3: free spins treated as their own case. Spins winnings carry their own, usually much steeper, multiplier (35x on $60 is $2,100 here). Tools that only model deposit bonuses leave casino players to guess at the one figure that surprises them most.
Frequently asked questions
It is the total amount you must bet before bonus money or winnings from it can be withdrawn, set by the sportsbook or casino as a multiplier. A 8x rollover on a $100 bonus means wagering $800 in total bets if the multiplier applies to the bonus only. Rollover, wagering requirement and playthrough all mean the same thing.
The basis is the amount the multiplier applies to. Bonus only is the smallest: $100 bonus at 8x is $800. Deposit only applies it to your deposit. Deposit plus bonus is the largest: a $200 deposit plus a $100 bonus at 8x is $2,400, three times the bonus only figure on the same offer. The basis is written in the bonus terms, and it is the single most important line in them.
No. The requirement counts total stakes placed, win or lose, not losses. Wagering $2,400 means the sum of your bet stakes reaches $2,400. You will usually lose some of it to the book's margin along the way, which is the real cost of clearing, but you do not need to lose $2,400 and most people who clear a bonus lose far less than the headline figure.
It divides the requirement by your average stake to get the number of bets, then divides by your bets per day to get the days needed. A $2,400 requirement at $25 a bet is 96 bets. At 4 bets a day that is 24 days, wagering $100 a day. If you enter the bonus expiry, the plan checks the schedule against it and warns you when the days do not fit.
Free spins usually pay bonus winnings that carry their own multiplier. The tool multiplies the net winnings by the spins multiplier: $60 of winnings at 35x is a $2,100 wagering requirement. The spins themselves are free. It is the winnings that are locked until that turnover is met, and unmet winnings are typically removed when the offer expires.
Often not, and this calculator counts stakes at face value, so read it as the minimum schedule. Many casinos weight games differently (slots often 100%, table games much less) and many sportsbooks exclude very short priced bets or bets on both sides of one event. If your terms apply a contribution percentage, divide the requirement by that percentage to get the true amount you must stake.
In most terms the bonus and any winnings generated from it are removed, while your remaining cash balance stays yours. That is why the expiry check matters before you accept: a $2,400 requirement needing 24 days at your normal pace is a reasonable offer with a 30 day window and a trap with a 7 day window, because clearing faster means betting bigger or more often than you planned.
Sometimes, for someone who would place those bets anyway at those stakes: the rollover then costs nothing extra in behaviour. It is rarely worth changing how you bet to chase one. The expected cost of clearing is roughly the requirement multiplied by the margin on the bets you place, and if that cost approaches the bonus value, the offer is decoration. Never deposit money you cannot afford to lose to unlock a bonus.
