Wagering Calculator

Enter the numbers from the offer terms and this tool tells you the total amount you have to stake before any bonus winnings become real money. Game weighting is included, because that single line in the terms is what turns a manageable requirement into an unrealistic one.

What a wagering requirement actually is

A wagering requirement is the total value of bets you must place before the casino will let you withdraw anything you won with bonus funds. It is expressed as a multiplier — 10x, 20x, 35x — applied either to the bonus alone or to your deposit plus the bonus. The difference between those two bases is enormous and it is the first thing to check in any offer.

A £50 bonus at 10x on the bonus only means £500 of bets. The same 10x applied to deposit plus bonus, where you deposited £50, means £1,000 of bets. Identical headline number, double the work. Operators are required to state which basis applies in the significant terms, and every offer we list is checked against that line before it appears on the site.

Wagering is a turnover figure, not a loss figure. You are not required to lose the money. Each time you place a bet, the stake counts towards the requirement whether it wins or loses, and winnings recycle back into further bets. That is why a requirement of £500 does not mean you need £500 of your own money — but it does mean prolonged exposure to the house edge, which is what the bonus value calculator quantifies.

Game weighting is the part that catches people out

Weighting is the percentage of each bet that counts towards the requirement. Slots almost always count 100%. Roulette, blackjack, video poker and most live dealer tables count far less — commonly 10%, sometimes 5%, and often 0% for the lowest-edge variants. A £10 bet on a table counting 10% contributes £1 to your requirement.

Run the numbers with the weighting field set to 10% and the effect is obvious: a £500 requirement becomes £5,000 of actual bets. This is not an accident of design. Table games have a lower house edge than slots, so operators reduce their contribution to protect the economics of the offer.

The practical consequence is that if you prefer live blackjack or roulette, most deposit-match bonuses are not built for you. Wager-free offers and cashback schemes are usually the better route, because they place no playthrough condition on how you like to play.

The UK 10x cap changed the maths

Since January 2026, wagering on new UK casino bonuses is capped at 10x, and offers that mix casino and sports products in a single bonus are banned. That is why the calculator defaults to 10x. Before the cap, 35x and 65x offers were routine, and clearing them was realistically out of reach for most players.

The cap does not make every bonus good. A 10x requirement on deposit plus bonus, with 10% game weighting, a £5 maximum bet rule and a seven-day expiry, is still a demanding offer. What the cap did was compress the range, which pushes the real differences into the other terms — maximum conversion, expiry window, and whether the bonus is sticky.

It also raised the relative value of wager-free offers. When the worst case is 10x rather than 65x, a 0x offer is no longer in a different universe — but it is still the cleanest product on the market, because winnings are paid as cash you can withdraw immediately.

The terms that matter as much as the multiplier

Maximum conversion caps what you can keep. Some offers limit bonus winnings to a fixed sum or a multiple of the bonus, so a large win on bonus funds gets trimmed to the cap when it converts.

Maximum bet rules limit your stake while a bonus is active, commonly £5 per spin or per hand. Breach it once, even accidentally on an autoplay setting, and the operator is generally entitled to void the bonus and any winnings from it.

Expiry windows decide whether the requirement is achievable at all. A £500 requirement over 30 days is a different proposition to the same figure over seven. Divide your total by the number of days you realistically play and see whether the daily stake is one you would place anyway.

Sticky versus non-sticky matters at withdrawal. A non-sticky bonus keeps your cash and bonus balances separate, so you can withdraw your own money at any time. A sticky bonus merges them, and withdrawing before the requirement is cleared forfeits the bonus and often the winnings with it.

• Which balance the multiplier applies to — bonus only, or deposit plus bonus
• Game weighting for the games you actually play, plus the excluded list
• Maximum conversion and whether it applies to free spins winnings too
• Maximum bet while the bonus is live
• Expiry in days, counted from credit rather than from first use
• Whether the bonus is sticky or non-sticky

How to use the result

Treat the output as a turnover budget, not a target. Compare it against what you would stake in a normal month at your usual bet size. If clearing the offer would require you to play more, faster or at higher stakes than you otherwise would, the correct decision is to decline the bonus and play with cash — every UK casino allows you to opt out at the cashier.

We never present a bonus as a reason to deposit more. The calculator exists to make the cost visible, and a fair number of offers look considerably less attractive once you see the turnover written down as a single figure.
