Wagering Requirements Calculator

Wagering requirements (also called playthrough requirements or rollover) are conditions attached to casino bonuses that dictate how much you must bet before you can withdraw any winnings. For example, a $100 bonus with 35x wagering means you must place $3,500 worth of bets before cashing out. This is how casinos ensure that bonuses are not simply free money. They are incentives to play, and the house edge erodes the bonus value with every wager.

Most casino bonuses are mathematically -EV (negative expected value). Here is why: if you must wager $3,500 on a game with 96% RTP (4% house edge), the expected cost is $3,500 × 0.04 = $140. That means a $100 bonus will, on average, cost you $140 to clear, leaving you $40 worse off than if you had never claimed it. The casino profits from the difference.

To identify a genuinely valuable bonus, look for low wagering multipliers (under 20x), bonuses that apply to the bonus amount only (not bonus + deposit), and terms that allow high-RTP games to count at 100%. A $50 bonus with 10x wagering on bonus only requires just $500 in wagers. At 97% RTP, the expected cost is only $15, leaving you with a net $35 profit from the bonus.

Game contribution rates are a critical factor many players overlook. Casinos often restrict how much different games contribute toward clearing wagering requirements. Slots typically count 100%, but blackjack may only count 10%, and roulette 20%. If you play a game with 10% contribution, your effective wagering requirement is 10x higher. A 35x requirement on $100 becomes $35,000 in actual bets, not $3,500.

Tips for evaluating bonuses: Always calculate before claiming. Play the highest-RTP game that has 100% contribution. Check if there is a maximum bet limit (common for bonus play). Look for no-deposit bonuses or free spins with low wagering. These are the most likely to be +EV. If the break-even RTP is above 98%, the bonus is almost certainly not worth it because very few games offer such returns. And remember: if a bonus seems too generous, read the fine print, there is always a catch.

Wagering requirements (also called playthrough requirements) are conditions attached to casino bonuses that require you to bet a specified multiple of the bonus (and sometimes your deposit) before you can withdraw any winnings. For example, a "30x wagering requirement" on a $100 bonus means you must place $3,000 in total bets before the bonus converts to withdrawable cash.

Wagering requirements exist because casinos would lose money if players could deposit, claim a bonus, and immediately withdraw. The requirements ensure the casino has a reasonable statistical expectation of recovering the bonus cost through the house edge applied to your wagers. From the player's perspective, they represent the "price" of the bonus, and whether that price is worth paying depends entirely on the math.

Modern wagering requirements vary widely: low requirements (10 to 20x) are genuinely valuable; moderate requirements (25 to 40x) can still have positive EV depending on the bonus size and game selection; high requirements (50x+) are typically unprofitable for most players and are designed primarily to attract recreational gamblers who will not complete them.

The mechanics are straightforward but the implications are easy to underestimate. Each time you place a qualifying bet, the wagered amount is counted toward your requirement. Whether you win or lose that bet, the wagered amount still counts. The bonus becomes withdrawable once the total wagered amount equals the required multiple.

However, most casinos apply game contribution weights, different games count different percentages of each bet toward the requirement. Slots typically count 100%, while table games like blackjack may count only 10 to 20% (or be excluded entirely). This is not arbitrary: table games have lower house edges, so casinos need more wagers from them to expect the same mathematical return.

This shows why game contribution weights matter enormously. A bonus that appears attractive can become deeply negative EV once you account for the actual wagering volume required on high-contribution games versus low-edge games.

The true cost of a bonus is the expected loss you will incur clearing the wagering requirement. This is the only figure that matters when deciding whether to claim a bonus.

Always calculate bonus EV before accepting. The headline bonus amount is irrelevant, what matters is whether the expected loss to clear it is less than the bonus value.

If you've determined a bonus has positive EV and you're committed to clearing it, execution matters. The goal is to minimize actual losses while completing the requirement. Key strategies:

Choose the highest RTP game with 100% contribution: Not all slots are equal. A 98% RTP slot with 100% contribution costs half as much per dollar wagered as a 96% RTP slot. Check the paytable or game info screen for RTP before starting.

Avoid progressive jackpot games: Progressive slots often have lower base-game RTPs (92 to 94%) because a portion of each bet feeds the jackpot pool. The jackpot EV is real but requires enormous luck to realize. For bonus clearing purposes, stick to regular video slots with published RTPs above 96%.

Track your progress explicitly: Many casinos display your wagering progress in the promotions section or balance area. Check it regularly. Running out of bonus funds before completing the requirement is a common outcome. Once the bonus is gone, you're just wagering your own money.

Set a stop-loss: Even on positive EV bonuses, variance can cause you to bust your bonus balance before completing the requirement. Decide in advance what balance level triggers you to stop, accepting the loss rather than chasing with your own funds.
