Average outcomes from a simplified expected-value model. Real sessions vary a lot: many players lose the bonus before finishing, a few finish well ahead. Check the operator's terms for excluded games, max bet rules and expiry.

How it works

A wagering requirement says how many times a bonus (or bonus plus deposit) must be bet before winnings can be withdrawn. Every bet loses the house edge on average, so the requirement has a price: the expected loss on all the bets it takes. The calculator compares that price with the bonus itself.

The formula

wagering in money = (bonus, or bonus + deposit) × requirement
real stakes = wagering in money ÷ game weighting
expected loss = real stakes × (1 − RTP)
value if you finish = min(max(0, bonus − expected loss), max cashout)

Worked example

  • £100 bonus, 35x on the bonus, played on a 96% RTP slot: £3,500 of bets with an expected loss of £140. The bonus is worth less than the betting costs, so a typical finisher keeps nothing.
  • The same £100 at the UK maximum of 10x: £1,000 of bets, £40 expected loss, £60 kept on average.
  • At 35x on bonus plus a £100 deposit the bets double to £7,000 and the expected loss to £280.
  • Played on blackjack at 10% weighting and 99.5% RTP, 10x on £100 means £10,000 of real bets and a £50 expected loss.

The model shows averages and ignores variance. For the operator's side, the Bonus Cost Calculator uses the same method and adds completion rates and gaming tax.

Frequently asked questions

How do I calculate a wagering requirement?

Multiply the amount the requirement applies to by the multiple. A £100 bonus with 35x wagering on the bonus means £3,500 of bets. If wagering is on bonus plus deposit and you deposited £100, it is 35 × £200 = £7,000. Games that count less than 100% raise the real stakes: at 10% weighting every £1 bet counts as 10p.

What is a good wagering requirement?

Lower is better for the player. On a 96% RTP slot the expected loss equals the bonus at 25x on the bonus, so above roughly 25x a typical player is expected to lose more while wagering than the bonus is worth. In the UK, requirements above 10x are no longer allowed since 19 January 2026.

What does 'value if you finish' mean?

What a player who completes the wagering keeps on average: the bonus minus the expected loss on the required stakes, never below zero and capped by any max cashout. It is an average. Many players lose the bonus before they finish and a few finish well ahead.

Why does game weighting matter so much?

Weighting divides your real stakes. Blackjack counting 10% turns £1,000 of wagering into £10,000 of bets, so even a low house edge produces a large expected loss. Check the terms: many operators exclude table games entirely.

Is this calculator for players or operators?

Both. Players can see what an offer is really worth before claiming it. Operators can see how their requirement compares with the market; the Bonus Cost Calculator then turns the same offer into a cost per player after gaming tax.
