Wagering Requirements Explained: The Maths Behind Bonus Terms

Written by James Huntington. Last updated November 2026.

A wagering requirement is the number of times you have to bet a bonus before the casino lets you withdraw anything won with it. A $100 bonus with 30x wagering means placing $3,000 in bets first. That is the whole idea. The confusion comes from the different ways casinos apply it, and from the other terms that sit alongside it.

This guide covers how the calculation works, what the numbers cost you in real terms, and which bonus terms are worth walking away from. I have kept the maths simple, but I haven’t skipped it, because the maths is what decides whether a bonus is worth having.

How is a wagering requirement calculated?

The basic sum is the wagering base multiplied by the multiplier. The multiplier is the “x” number in the terms. The base is where casinos differ, and it changes the answer a lot.

Bonus only

The most common version. You multiply the bonus amount alone. Deposit $100, get a $100 match, 30x the bonus: you need to bet $3,000.

Bonus plus deposit

The tougher version. You multiply the bonus and your deposit together. Same $100 deposit and $100 bonus at 30x: you now need to bet $6,000. A 30x bonus-plus-deposit term is the same as 60x on the bonus alone, when the match is 100%. This is the detail I check first, because it is easy to miss and it doubles the work.

Free spin winnings

With free spins, the spins themselves are not wagered. Whatever you win from them is credited as bonus money, and that amount is multiplied. Win $8 from your spins at 40x, and you need to bet $320. The free spins guide covers how spin offers differ from bonus cash.

Deposit only

Occasionally you will see wagering on the deposit alone, often 1x to 3x. This is usually an anti-money-laundering rule rather than a bonus term. It stops people depositing and withdrawing straight away without playing.

What does a wagering requirement actually cost you?

Here is the part most bonus pages leave out. Wagering does not just take time. It costs money on average, because every bet you place carries the house edge.

A slot with 96% RTP has a house edge of about 4%. Over a long run, you lose about $4 for every $100 you bet. So the expected cost of clearing a bonus is roughly:

Expected cost = total amount you must bet × house edge

If that cost is less than the bonus, the bonus is worth something on average. If it is more, the bonus is worth nothing on average, and your own deposit starts paying for the difference.

Here is how that plays out on a $100 bonus, wagered on the bonus only, on slots with a 4% edge.

There is a neat shortcut hidden in that table. The break-even multiplier is 1 divided by the house edge. At a 4% edge, that is 25x. At a 3% edge, from a 97% RTP slot, it is about 33x. Anything above the break-even point means the bonus, on average, is used up by the house edge before you finish.

A few honest caveats. These are averages, and real sessions swing a lot. Some people will clear a 45x bonus with money to spare, and many will bust out early on a 20x one. The figures also ignore cashout caps, which cut off the best outcomes. And the RTP a casino shows is a long-run figure for the game, not a promise for your session. Use the sum to compare offers, not to predict what will happen to you.

It also explains why no deposit offers, which often carry around 45x, usually end at zero. That’s fine when none of the money was yours. It is a different story when your deposit is in the same pot. I go through the no deposit side in no deposit bonuses explained.

Why do some games barely count towards wagering?

Most casinos publish a contribution table. It says what share of each bet counts towards the requirement. A typical pattern looks like this, though every casino sets its own figures.

The effect is easy to underestimate. Divide the multiplier by the contribution to get the real figure. A 35x requirement on a game that counts 10% is effectively 350x. That turns a bonus into a chore with a cost attached.

The reason is simple. Table games have a lower house edge than most slots, so if they counted in full, clearing a bonus would cost the casino less. Low contribution rates close that gap. It is the same reason certain high-RTP slots are often on the excluded list. If you mainly play blackjack or live tables, read live casino and blackjack bonuses before you claim anything.

What is the max bet rule, and why does it void so many bonuses?

While a bonus is active, most casinos cap each bet. On slots this is often around $5 or €5 per spin, and sometimes lower on no deposit offers. The terms will give the exact figure.

Two things make this rule dangerous. First, the casino usually checks it when you ask to withdraw, not while you play. You can break it early in a session, play on for hours, clear the wagering, and then lose the whole balance at the cashier. Second, some casinos treat doubling features or gamble buttons on slots as a breach, even when the base bet was fine.

My rule of thumb: set your stake well under the cap before you start, and leave it there. Don’t use autoplay settings that raise the stake after a win. Max-bet rules voiding bonuses come up again and again in withdrawal disputes, and the casino is almost always within its terms.

How long do you get to complete the wagering?

Usually somewhere between a few days and 30 days, and the clock often starts when the bonus is credited, not when you first play. Miss it and the bonus, plus anything won with it, is removed.

Codes posted in Telegram channels often have even shorter windows, which I explain in how Telegram casino bonus codes work. It is worth doing the sum on time as well as money. $4,500 of wagering at $1 a spin is 4,500 spins. That is several hours of continuous play, possibly more. If the window is seven days and you play a couple of evenings a week, a high multiplier may simply not be achievable. Don’t let an expiry date push you into playing longer or faster than you would choose to.

What other bonus terms should you read?

Wagering gets the attention, but these terms often matter just as much.

• Maximum cashout. A cap on what you can withdraw from the bonus. On no deposit offers, $50 or €50, or 10 times the bonus, is common. On deposit bonuses it is less common, but check.
• Which money is played first. Some casinos use your cash balance first, others lock your deposit and bonus together until wagering is finished. The difference decides whether you can walk away with your deposit if you win early. I explain sticky and non-sticky bonuses in the welcome bonus guide.
• Withdrawing cancels the bonus. Requesting a withdrawal before the wagering is done usually forfeits the bonus and its winnings.
• Payment method exclusions. Some casinos exclude deposits from certain e-wallets or vouchers from bonuses. See the payment methods guide.
• Excluded countries. The bonus may not be available where you live, even if the casino accepts you.
• Bonus abuse clauses. Vague terms about “irregular play” give the casino room to refuse a payout. They are standard, but a casino that leans on them often is one to avoid. Repeat offenders end up on my list of blacklisted casinos.

Are no wagering bonuses better?

A no wagering bonus pays what you win as cash, with no playthrough. Free spins with no wagering are the most common form. What you win from the spins can be withdrawn straight away, subject to any cap and the usual identity checks.

The catch is size. Because the casino can’t recover the cost through wagering, these offers are smaller. Ten no wagering spins can easily be worth more in practice than a large matched bonus at 45x, because you actually get to keep the outcome. If you play casually and value a clean withdrawal over a big headline number, no wagering offers are usually the better fit. If you play a lot anyway, a low-multiplier deposit bonus can still make sense.

Can you clear wagering requirements faster?

Not really, and I’d be wary of anyone who says otherwise. Some of the advice you will see online goes against the terms or makes things worse.

• “Bet bigger to finish sooner.” You will hit the max bet rule, and bigger stakes mean bigger swings. Most people simply bust out faster.
• “Play low house edge table games.” They usually count at 0% to 10%, or are excluded. You end up betting far more in total.
• “Use bonus buys.” Many casinos ban feature buys during bonus play, and they count as a breach.

What does help is choosing well before you start. Pick lower multipliers on the bonus only. Check the contribution table covers what you like to play. Pick a stake that lets you finish within the time limit without going near the max bet. Track your progress in the bonus section of your account. And once the wagering is done, withdraw. Leaving a cleared balance to play on is how most “won” bonuses end up back with the casino. If the payout then takes longer than expected, Telegram casino withdrawal times explains what is normal and when to chase it.

Do wagering rules differ by country?

For licensed casinos, yes. In Great Britain, the Gambling Commission capped bonus wagering at 10x from January 2026. Other regulators set their own rules on bonuses and advertising.

Offshore and Telegram casinos, often licensed by the Curaçao Gaming Authority, set their own terms, which is why multipliers of 35x to 45x and higher are still common there. They are also less protected. Many are not licensed in the countries they accept players from, and playing at them may not be legal where you live. Check your local law, and look at Telegram casino geo-restrictions if a site blocks you. Whatever a bonus says, it does not change what the law allows.

Quick answers

What does 40x wagering mean?

It means you must place bets worth 40 times the wagering base before you can withdraw. If the base is a $25 bonus, that is $1,000 in total bets. Check whether the base is the bonus only or the bonus plus your deposit, because the second doubles the total on a 100% match.

What is a good wagering requirement?

Lower is better. On a slot with a 4% house edge, the break-even point is about 25x on the bonus only. Below that, the bonus is worth something on average. Above it, the house edge is likely to use up the bonus before you finish.

Does the wagering requirement apply to my deposit?

Usually only to the bonus, but some casinos apply it to the bonus plus your deposit. That term is far harder to clear. It is written in the bonus terms, so check before you claim.

Which games count towards wagering?

Most slots count 100%. Blackjack, roulette and video poker usually count 0% to 20%, and some high-RTP or jackpot slots are excluded. Divide the multiplier by the contribution to get the real figure.

What happens if I go over the max bet with a bonus?

The casino can void the bonus and any winnings made with it, usually when you try to withdraw. Keep your stake well below the cap and avoid autoplay settings that raise the stake.

Can I withdraw before finishing the wagering?

You can request a withdrawal, but it normally forfeits the bonus and anything won with it. Depending on the casino, your remaining cash deposit may still be withdrawable.
