Wagering Requirements Explained (With the Maths)

A wagering requirement is the total amount you must bet before you can withdraw winnings from a casino bonus, written as a multiplier such as 35x. At 35x, a NZ$100 bonus means NZ$3,500 of bets before a cent of bonus money becomes withdrawable. The headline percentage on a welcome offer tells you almost nothing on its own. The wagering terms decide whether the bonus is worth taking. This guide shows the maths so you can judge any offer in under a minute.

Key takeaways

• Total wagering = multiplier × qualifying amount. A 35x bonus on NZ$100 = NZ$3,500 to bet.
• "Deposit plus bonus" wagering is far harsher than "bonus only", so check which applies.
• Game weighting means table-game bets often count 10% or less toward the requirement.
• Time limits, max-bet caps, and max-cashout rules can quietly void a bonus you have nearly cleared.

How to calculate a wagering requirement

The core formula is simple: total turnover = wagering multiplier × qualifying amount. The only thing that varies is what the "qualifying amount" is. Read the terms for one of two phrasings:

• Bonus only: the multiplier applies to the bonus money. Friendlier to the player.
• Deposit plus bonus: the multiplier applies to your deposit and the bonus combined. Much steeper.

Take a NZ$100 deposit that unlocks a NZ$100 bonus at 35x. Under bonus-only terms you wager 35 × NZ$100 = NZ$3,500. Under deposit-plus-bonus terms you wager 35 × NZ$200 = NZ$7,000, double the grind for the same headline offer.

Worked examples in NZD

The table below shows how the same NZ$100 bonus changes shape across common multipliers, assuming bonus-only wagering:

Bonus	Wagering	Total to bet	Verdict
NZ$100	20x	NZ$2,000	Reasonable
NZ$100	35x	NZ$3,500	Industry standard
NZ$100	50x	NZ$5,000	High, read carefully
NZ$100	70x	NZ$7,000	Avoid unless cash is large

As a rough benchmark, anything at or below 35x bonus-only is competitive in the New Zealand market. Once you pass 50x, the bonus is mostly a retention tool, and you should expect to lose most of it to the house edge before clearing.

Game weighting: why your bets count differently

Not every dollar wagered reduces your requirement equally. Casinos apply game weighting so that lower-edge games contribute less. Typical weightings look like this:

• Slots: usually 100%. A NZ$1 bet removes NZ$1 from the requirement.
• Roulette: often 10% to 20%. A NZ$10 bet removes NZ$1 to NZ$2.
• Blackjack and video poker: frequently 10% or excluded entirely, because the player edge is too good.

This matters more than the multiplier for table-game players. Clearing NZ$3,500 of wagering on blackjack at 10% weighting actually means NZ$35,000 of real bets. If you prefer table games, only take bonuses that weight them generously, or skip the bonus altogether.

The terms that quietly kill a bonus

Three clauses in the fine print void more bonuses than the wagering multiplier ever does:

1. Time limit: many bonuses expire in 7 to 30 days. Miss the window and any unconverted bonus and winnings are forfeited.
2. Maximum bet: exceeding a per-spin cap (often NZ$5 to NZ$10) while a bonus is active can void the whole balance, even by accident.
3. Maximum cashout: no-deposit bonuses in particular often cap winnings at a small multiple of the bonus, so a big win is trimmed to the cap.

We read every one of these clauses before listing an offer, because a generous-looking bonus with a NZ$5 max bet and a 7-day clock is a worse deal than a modest one with clean terms. Our full review process is on the methodology page.

Is the bonus even worth it?

Run a quick test on any offer: calculate the total turnover, factor the house edge of the games you will actually play, and compare it to a no-wagering alternative. A NZ$25 no-wagering bonus you keep outright can beat a NZ$200 bonus locked behind 45x deposit-plus-bonus terms. Bonuses are not free money. They are a trade, and the maths tells you whether it is a fair one. Before opting in, set your limits using our responsible gambling guide.

Frequently asked questions

What does 35x wagering mean?

35x wagering means you must bet 35 times the qualifying amount before bonus winnings can be withdrawn. Whether the multiplier applies to the bonus alone or the deposit plus bonus is set in the terms, so always check which.

How do I calculate the total I have to wager?

Multiply the wagering multiplier by the qualifying amount. For a NZ$100 bonus at 35x bonus-only, that is 35 × NZ$100 = NZ$3,500 in total bets. If the terms say "deposit plus bonus", you multiply the combined figure instead.

Why do my slot bets clear faster than my table game bets?

Because of game weighting. Slots usually count 100% toward wagering, while table games like blackjack or roulette often count 10% or less. A NZ$10 blackjack bet at 10% weighting only reduces your requirement by NZ$1.

Are no-wagering bonuses better?

Often yes, if the cash value is fair. A smaller bonus with no wagering requirement can be worth more in real terms than a large bonus locked behind 40x turnover, because you keep what you win without grinding through bets.
