Wagering Requirements Calculator
Enter your bonus amount and its wagering requirement to see exactly how much you must stake before you can withdraw. Free, instant, no sign-up. The calculator also shows your expected loss at your game's RTP, the point at which an offer stops being worth taking, and it handles both bonus-only and deposit-plus-bonus terms as well as game weighting.
- Free and instant. No sign-up, no email, nothing to install.
- Works in any currency. Wagering is pure multiplication, so the answer holds whatever you deposit in.
- Real cost, not just turnover.See the expected loss at your game's RTP, not only the stake to play through.
Check the offer terms: the same headline multiplier can mean twice the stakes depending on which one applies.
At 10% contribution, £10 of stakes counts as £1 towards the requirement — so you stake ten times the headline figure.
True Bonus Cost
On these terms the expected cost of clearing the wagering is lower than the bonus, leaving £20.00 of expected value. That combination is uncommon and usually depends on a low multiplier and a high-RTP game being eligible.
Break-even point: at these RTP and contribution settings, this bonus stops being worth taking above 12.5× wagering.
How Wagering Is Calculated
A casino bonus reads as free money, but the wagering requirement means you have to put the qualifying amount through the games many times over before anything can be withdrawn. Every stake carries the house edge, so the requirement has a predictable average cost. That cost is what this calculator puts a number on.
The formula: qualifying amount × multiplier = the stakes you must place; divide that by the game contribution if your game counts for less than 100%, and the expected cost of those stakes is stakes × house edge, where the house edge is 100% minus the RTP. That is the whole of it, and the four steps below are the same formula with the numbers filled in. For the same ground in plain English, see casino bonus wagering explained.
The Formula, in Four Steps
1. Bonus amount = Deposit × Bonus percentage. A £100 deposit with a 100% match gives a £100 bonus.
2. Wagering to clear = Qualifying amount × Multiplier. The qualifying amount is either the bonus alone or the deposit plus the bonus, and the offer terms decide which. At 35×, bonus-only means £3,500; deposit plus bonus means £7,000 on the same offer.
3. Stakes you actually place = Wagering to clear ÷ Game contribution. If your game contributes 100%, the two figures match. At 10%, clearing £3,500 means placing £35,000 of stakes.
4. Expected loss = Stakes placed × House edge, where the house edge is 100% minus the RTP. £7,000 of stakes on a 96% RTP slot has an expected loss of £280 — against a £100 bonus, an effective value of −£180.
Game Contribution Is the Detail That Catches People Out
Contribution rates sit in the bonus terms rather than in the headline, and they change the answer more than the multiplier does. Typical UK values:
| Game | Typical contribution | Stakes to clear £3,500 |
|---|---|---|
| Slots | 100% | £3,500 |
| Video poker | 20% | £17,500 |
| Roulette | 20% | £17,500 |
| Blackjack | 10% | £35,000 |
| Live dealer tables | 0–10% | £35,000 or excluded |
The trap is that the games with the friendliest RTP are usually the ones with the lowest contribution. Blackjack at 99% RTP looks cheap per pound staked, but at 10% contribution you place ten times as many pounds, and the two effects cancel out or worse.
What the Break-Even Figure Tells You
The break-even line under the results is the multiplier at which the expected cost of clearing exactly equals the bonus. On a 96% RTP slot with full contribution, a bonus-only requirement breaks even at 25×; anything higher has a negative expected value before you place a single bet. On the same game, a deposit-plus-bonus requirement on a 100% match breaks even at 12.5×. Most advertised offers sit well above both.
What This Calculator Does Not Cover
Expected loss is a long-run average, not a prediction of one session. The calculator also leaves out maximum bet limits while a bonus is active, time limits for clearing, maximum win caps on bonus funds and excluded games — all of which appear in the terms and all of which make an offer worse, never better. Read the terms alongside the number.

The UK capped wagering requirements at 10× on 19 January 2026
Operators licensed in Great Britain can no longer require customers to play through bonus funds more than ten times, and can no longer combine gambling products inside one incentive. The calculator now defaults to 10×. The 35× figures used in the worked examples above are deliberate: they show the market this rule was written to end, and why the change matters more than it sounds. Full detail in the 10x wagering cap explained.
Frequently Asked Questions
What is the maximum wagering requirement allowed in the UK?
Ten times the bonus. Since 19 January 2026, Social Responsibility Code provision 5.1.1 has stopped operators licensed in Great Britain from requiring customers to play through bonus funds more than 10 times, and from mixing gambling products inside a single incentive. On a £100 bonus that is £1,000 of stakes rather than the £3,500 a 35× requirement once demanded. The 10x cap explained sets out what the rule does and does not cover.
How do I know whether the multiplier applies to the bonus only or to deposit plus bonus?
It is stated in the bonus terms, usually as "wagering applies to bonus funds" or "wagering applies to deposit and bonus". It is worth finding before you claim, because on a 100% match the second version doubles the stakes required and doubles the expected cost of clearing the offer.
Do all games count the same towards wagering requirements?
No. Slots usually contribute 100%, while table games such as blackjack and roulette often contribute 10% or less and some titles are excluded altogether. A game contributing 10% means £10 of stakes counts as £1 towards the requirement, so the real cost of clearing the bonus rises accordingly.
Why does the game's RTP change the result?
The expected loss while clearing a bonus is approximately the total stakes multiplied by the house edge, and the house edge is 100% minus the RTP. A 99% RTP game therefore costs roughly a quarter of what a 96% game costs over the same amount of stakes.
Does a bonus with a high wagering requirement still have value?
Often less than the headline figure suggests. Every pound wagered carries the game's house edge, so the expected cost of clearing the requirement has to be subtracted from the bonus. On a 96% RTP slot, clearing £3,500 of wagering costs around £140 on average, which is more than a £100 bonus is worth.
