Knowing how to calculate a casino wager is the first essential skill for figuring out whether a bonus is actually worth claiming. The base formula is simple — bonus amount × wager multiplier = total stakes required — but plenty of players get it wrong because of the finer details (wager on bonus only vs. bonus + deposit, variable game contribution, maximum bet allowed while wagering).
This article explains how to correctly calculate any casino wager in 2026, gives you the formulas for every scenario (deposit bonus, free spins, cashback), a reference calculator, and worked examples using top-rated bonuses (BonRush 400% wager x50, Millioner 200% wager x35, and more).
TL;DR — Calculating a wager in 4 points
- Base formula:
bonus amount × wager = total stakes required. A €100 bonus with a x35 wager = €3,500 in stakes before you can withdraw. - Two wager types: "on bonus only" (the calculation above) or "on bonus + deposit" (multiplies both amounts together). Always read the terms.
- Variable contribution: slots = 100%, blackjack = 5-10%, roulette = 10-20%, jackpots = excluded. The wager clears fastest on slots.
- Maximum bet while wagering: generally €5/spin at most casinos. Exceeding it usually voids the bonus.
The base formula: amount × wager = stakes
Simple formula (wager on bonus only)
�CODEBLOCK_0�
Example: you receive a €200 bonus with a x35 wager.
- Calculation: 200 × 35 = €7,000 in stakes to complete
That figure is your cumulative stake volume on games that contribute (slots = 100%). If you bet €5 and win €8, you've staked €5 — that's +€5 toward your wager. If you then re-stake that €8 and lose, you've staked another €8 — +€8 toward your wager. Total after those two spins = €13 wagered.
Full formula (wager on bonus + deposit)
Less common, but worth knowing: some casinos apply the wager to (bonus + deposit).
�CODEBLOCK_1�
Example: you deposit €200, receive a €200 bonus (100%), with a x35 wager on bonus + deposit.
- Calculation: (200 + 200) × 35 = €14,000 in stakes — that's twice as much as wagering on the bonus alone.
⚠️ Always check the terms: "Wager applies on bonus only" or "Wager applies on bonus + deposit" (both amounts). Most top-rated brands in 2026 apply the wager to bonus only — the more player-friendly option.
Reference calculator — Top 2026 bonuses
Here's the calculated wager for the leading bonuses among our top-rated brands:
| Casino | Bonus % | Cap | Wager | Sweet-spot deposit | Total wager to clear |
|---|---|---|---|---|---|
| BonRush | 400% | €2,000 | x50 | €500 | €100,000 |
| Millioner | 200% | €2,500 | x35 | €1,250 | €87,500 |
| Lizaro | 250% | €500 | x40 | €200 | €20,000 |
| Betti | 150% | €750 | x35 | €500 | €26,250 |
| SpinAura | 100% | €15,000 | x40 | €15,000 | €600,000 |
| BetMac | 100% | €525 | x35 | €525 | €18,375 |
| BetRiviera | 100% | €1,000 | x35 | €1,000 | €35,000 |
How to read it: at the €500 sweet spot with BonRush → €2,000 bonus → x50 wager = €100,000 in stakes to clear within 7 days = roughly 5h45 of play per day at a €5/spin max bet × 500 spins/hour.
How long does it actually take?
The math of wagering time
At a €5/spin maximum bet × 500 spins/hour (typical auto-spin pace on classic slots) = €2,500 in stake volume per hour.
To clear X € of wager, you need roughly X ÷ 2,500 hours:
| Total wager | Hours of play | Spread over 7 days |
|---|---|---|
| €5,000 | 2h | 17 min/day |
| €10,000 | 4h | 35 min/day |
| €20,000 | 8h | 1h10/day |
| €35,000 | 14h | 2h/day |
| €50,000 | 20h | 2h45/day |
| €100,000 (BonRush sweet spot) | 40h | 5h45/day |
| €600,000 (SpinAura sweet spot) | 240h | 34h/day ❌ — unrealistic over 7 days |
How to read it: for the SpinAura sweet spot at €15,000, the x40 wager comes to €600,000, which needs 240 hours of play — impossible in 7 days. Either deposit less (€5,000 → €200,000 wager → 80h over 30 days = 2.5h/day, doable), or accept that the bonus won't be fully cleared.
Specific cases
Wager on free spins
When you receive X free spins, the winnings from those spins are subject to the main bonus wager. Millioner example:
- 200% bonus / €2,500 + 300 free spins
- You play the 300 spins, winning say €60 from them
- Total wager = (2,500 + 60) × 35 = €89,600 in stakes to clear (the €60 gets added to the initial bonus)
Wager on cashback
Cashback is usually wager-free (or x1 wager) — you receive money that's directly withdrawable. Kings Chance example:
- Weekly cashback of 15% on your net losses
- If you lost €100 that week → you receive €15 withdrawable the following week, no wagering required
- This is the key advantage of VIP cashback programs
Wager on no-deposit bonuses
Very high (often x40-x60) because the casino carries no risk (no deposit involved). Typical example:
- 25 no-deposit free spins, winnings capped at €100, x50 wager on the winnings
- If you win €50 from the spins → wager = 50 × 50 = €2,500 in stakes
- Often comes with a withdrawal cap too (e.g. max €100 withdrawable even if you win €500 during wagering)
Game contribution to the wager
Not every game contributes 100% to the wager. Standard 2026 contribution table:
| Game type | Average contribution |
|---|---|
| Classic slots (NetEnt, Pragmatic, Play'n Go) | 100% |
| Premium niche slots (Hacksaw, Yggdrasil, BGaming) | 100% |
| Table games (blackjack, roulette) | 5-20% |
| Live casino (Evolution, Pragmatic Live) | 10% |
| Video poker | 5-15% |
| Progressive jackpots (Mega Moolah, Hall of Gods) | 0% (excluded) |
| Sports betting (integrated bookmaker) | Separate wager |
Consequence: to clear a €100,000 wager, playing €100,000 on classic slots completes the wager. Playing €100,000 on live blackjack (10%) only validates €10,000 of wager — you'd still have €90,000 left to make up elsewhere. Always stick to slots during the wagering phase.
Maximum bet while wagering
2026 market standard: €5/spin maximum during the wagering phase. Exceeding it usually means the bonus gets voided (a standard clause in the terms).
For high rollers used to €50-€200 bets per spin, that's restrictive. The workaround: clear the wager quickly at €5/spin (40h for €100,000), then go back to your usual bet size once the wager is complete.

FAQ — How to calculate a casino wager
What's the simple wager formula?
Total stakes = Bonus amount × Wager multiplier. Example: a €200 bonus × 35 = €7,000 in stakes to complete before you can withdraw.
How do I know if the wager applies to bonus only or bonus + deposit?
Read the bonus terms under "Wagering Requirements". Look for the phrases: "wager applies on bonus only" (bonus only, more favorable) or "wager applies on (bonus + deposit)" (both amounts, doubles the wager). Most top-rated brands in 2026 use "bonus only".
Is the wager the same for every game?
No. Slots contribute 100% to the wager, blackjack 5-10%, roulette 10-20%, live casino ~10%, and progressive jackpots 0% (excluded). To clear the wager as fast as possible, stick to classic slots.
How long does a x40 wager on a €1,000 bonus take?
Calculation: 1,000 × 40 = €40,000 in stakes. At €5/spin × 500 spins/hour = €2,500/hour. That's 16 hours of play in total. Over a 7-day validity window that's 2h20 per day — achievable for a regular player.
What's considered a "reasonable" wager?
x30-x35 is on the low end (favorable). x40 is the standard. x45-x50 gets strict (typically reserved for huge bonus percentages like 400%). Beyond x50, the bonus has very little real value because the required stake volume usually exceeds what a player can realistically achieve within the validity period.
What happens if I exceed the maximum bet while wagering?
Bonus voided (a standard terms clause). If you bet €10/spin when the limit is €5/spin, the casino can detect it automatically and void the bonus plus any winnings derived from it. Your original deposit stays yours, but that's it. To avoid this, use auto-spin set to exactly €5/spin.
Is there an online wager calculator?
Yes. Search "wager casino calculator" on Google. But the formula is so simple you don't really need a tool: just multiply your bonus by the wager multiplier. That's it.
How does wagering on free spins work?
Winnings from free spins are subject to the main bonus wager. Example: you play 100 free spins and win €30 → that €30 gets added to your initial bonus for the wager calculation. If the initial bonus is €1,000 with a x35 wager plus €30 in spin winnings, the total wager becomes (1,000 + 30) × 35 = €36,050.
