Wagering calculator

A wagering requirement is a turnover target. Before the operator will let you withdraw anything from a bonus, you have to place bets adding up to a multiple of a figure the terms name. The whole argument is over which figure.

Bonus-only versus deposit plus bonus

British bonus wagering requirements have been capped at 10 times since 19 January 2026. Higher multiples here are historical or international worked examples, not current British offers. Take a £100 deposit with a 100% match at 35× wagering. If the multiplier applies to the bonus only, the target is 35 × £100 = £3,500 of turnover. If it applies to deposit plus bonus — the same headline offer, one clause different — the target is 35 × £200 = £7,000. That single word doubles the work, and it is why the calculator asks. An offer advertising a lower multiplier on deposit + bonus can easily cost more than a higher one on the bonus alone.

Game weighting

Not every bet counts in full. Slots usually contribute 100%, but table games are commonly weighted at 10% and some — live dealer, video poker, anything with a low house edge — are excluded outright or capped. At 10% weighting, £10 staked on roulette moves the target by £1. Clearing a £3,500 requirement on a 10%-weighted game means £35,000 of real bets.

The limits that decide whether it is worth it

Three clauses matter as much as the multiplier. The maximum bet while wagering — often £5 — means the target cannot be cleared in a few large bets, and breaching it usually voids the bonus outright. The time limit, commonly 7 to 30 days, is what makes a large requirement impossible rather than merely slow. And the maximum cashout caps what you can take out no matter what you win, which is the clause that most often turns a headline figure into a much smaller real one.

What the number does and does not tell you

Turnover is not loss. Wagering £3,500 does not mean losing £3,500. Each bet returns most of its stake on average, and the expected cost of clearing a requirement is roughly the turnover multiplied by the game’s house edge. That is a long-run average across many players, not a forecast of your session, and the variance around it is wide in both directions. A wagering requirement is best read as an estimate of how much work a bonus demands before it becomes money you own — not as a prediction of what you will end up with.
