Every casino bonus comes with a number — 20×, 35×, 50× — that determines how much you must wager before the bonus becomes withdrawable cash. Understanding wagering requirements explained in real terms, not marketing terms, is the difference between claiming a bonus that has actual value and claiming one that costs you more than it gives. This guide covers what wagering requirements are, how the three main models work, the formula that reveals the real cost of any bonus, why game contribution rates change the math dramatically, and how to calculate whether a specific offer is worth claiming — or whether you should skip it and play without a bonus entirely.
What Are Wagering Requirements? The Core Concept Explained
Wagering requirements are the total amount of money you must bet before bonus funds (or winnings from bonus funds) become withdrawable real money. When a casino says a bonus has “35× wagering,” it means you must place total bets equal to 35 times a specified base amount before you can cash out. Wagering requirements explained simply: they are a turnover target — not an amount you must lose, but an amount you must bet through. The house edge takes its cut on every bet, which is why wagering requirements have a real mathematical cost even though you are “just” placing bets.
Wagering Requirements Explained — Key Numbers
The Wagering Requirements Formula — And the Real Cost Nobody Shows You
Most guides explain what wagering requirements are. Almost none explain what they cost. The formula that matters is not just the turnover calculation — it is the expected loss calculation, because that is what determines whether a bonus has positive or negative value.
Total wagering = Base amount × WR multiplier
Step 2 — Calculate expected loss during wagering
Expected loss = Total wagering × (1 − RTP)
Step 3 — Calculate net value of the bonus
Net value = Bonus amount − Expected loss
Example:
€100 bonus, 35× bonus-only wagering, playing at 96% RTP
Total wagering: €100 × 35 = €3,500
Expected loss: €3,500 × 0.04 = €140
Net value: €100 − €140 = −€40
The “free” €100 bonus costs you €40.
This is the insight that changes everything about how you evaluate bonuses. A bonus is not “free money” — it is a promotional value that comes with a cost attached via wagering requirements. If the expected loss during clearing exceeds the bonus value, the bonus has negative expected value and you would be mathematically better off playing without it. The Wager Bonus Calculator computes this automatically for any bonus you are considering.
The RTP trap: The cost calculation above assumes you play at 96% RTP. Many casinos run slots at reduced RTP configurations — 94% or even 92%. At 92% RTP, the same €100 bonus with 35× wagering costs: €3,500 × 0.08 = €280 in expected losses. The “free” €100 bonus costs you €180. Always check the RTP at your specific casino before calculating bonus value. How Slot Features Affect RTP explains why the same game can run at different RTPs on different casinos.
3 Wagering Requirement Models Explained
The multiplier (35×) is only half the equation. The other half is the base — what the multiplier applies to. This changes the total wagering dramatically, and it is the most commonly missed detail in bonus evaluation.
| Model | Formula | €100 Deposit + €100 Bonus at 35× | Expected Loss (96% RTP) | Net Value |
|---|---|---|---|---|
| Bonus-only | Bonus × WR | €100 × 35 = €3,500 | €140 | −€40 |
| Deposit + Bonus (D+B) | (Deposit + Bonus) × WR | €200 × 35 = €7,000 | €280 | −€180 |
| Winnings-only (free spins) | Winnings × WR | Varies — depends on spin results | Varies | Usually marginal |
The same “35× wagering” produces €3,500 in required bets under bonus-only and €7,000 under deposit+bonus — exactly double. The expected loss doubles with it. This is why the wagering base matters as much as the multiplier. Bonus Only vs Deposit and Bonus Wagering covers this comparison in full depth.
Quick rule for wagering requirements explained practically: Bonus-only wagering at 35× is roughly equivalent to deposit+bonus wagering at 17.5× in terms of actual required turnover. When comparing offers between casinos, always convert to total required wagering first — not the headline multiplier. The Wager Bonus Calculator does this conversion automatically.
Wagering Requirements Explained: Worked Examples From 0× to 60×
All examples assume: €100 deposit, €100 bonus (100% match), bonus-only wagering, playing slots at 96% RTP.
| WR | Total Wagering | Expected Loss | Net Bonus Value | Spins at €1/spin | Verdict |
|---|---|---|---|---|---|
| 0× (no wagering) | €0 | €0 | +€100 | 0 | Pure value — always claim |
| 10× | €1,000 | €40 | +€60 | 1,000 | Strong positive value |
| 20× | €2,000 | €80 | +€20 | 2,000 | Marginally positive — worth claiming if terms are clean |
| 25× | €2,500 | €100 | €0 | 2,500 | Break-even point at 96% RTP — bonus costs what it gives |
| 35× | €3,500 | €140 | −€40 | 3,500 | Negative EV — only justified if terms allow early withdrawal |
| 50× | €5,000 | €200 | −€100 | 5,000 | Deeply negative — you’re paying €100 to play with “free” money |
| 60× | €6,000 | €240 | −€140 | 6,000 | Predatory — the bonus costs more than its face value |
The 25× Break-Even Rule
At 96% RTP (4% house edge), a bonus-only wagering requirement of 25× is the mathematical break-even point — the expected loss during clearing equals the bonus value. Below 25×, the bonus has positive expected value. Above 25×, you are paying more in expected losses than the bonus is worth. At lower RTPs, the break-even point drops: at 94% RTP, break-even is ~16.7×. At 92% RTP, break-even is ~12.5×. This is why RTP and wagering requirements must be evaluated together — the Wager Bonus Calculator factors both.
Game Contribution: Why Wagering Requirements Are Harder Than They Look
Game contribution rates determine how much of each bet counts toward clearing wagering requirements. Slots typically contribute 100% — every €1 bet clears €1 of wagering. Table games contribute 10–20%. Some games contribute 0%. This means the effective wagering requirement changes depending on what you play.
| Game Type | Typical Contribution | Effective WR at 35× Bonus-Only (€100 bonus) | Total Bets Needed |
|---|---|---|---|
| Online slots | 100% | 35× | €3,500 |
| Roulette | 20% | 175× effective | €17,500 |
| Blackjack | 10% | 350× effective | €35,000 |
| Live dealer games | 10% (or 0%) | 350× (or excluded) | €35,000 (or impossible) |
| Excluded games | 0% | Infinite — cannot clear | Bets don’t count at all |
The blackjack trap: A player who prefers blackjack (house edge ~0.5%) might think: “I’ll clear wagering on blackjack because the house edge is lower.” But 10% contribution means 10× more bets required. 35× bonus-only at 10% contribution = €35,000 in total bets. At 0.5% house edge: €35,000 × 0.005 = €175 expected loss. Compare to slots at 100% contribution: €3,500 total bets × 4% house edge = €140 expected loss. The lower contribution rate more than offsets the lower house edge. Slots are almost always the cheapest path to clear wagering requirements — which is exactly what the casino intended.
Hidden Terms That Change How Wagering Requirements Work
The multiplier and base are the headline numbers, but several other terms in the bonus conditions can make wagering requirements harder or invalidate your progress entirely.
Max Bet Rule
Most bonuses cap bet size during wagering at €5–€6 per spin. Exceeding the max bet — even accidentally — can void all bonus winnings and progress. Some casinos enforce this strictly with automated systems. Others only check after a withdrawal request. Either way, violating the max bet rule is the most common reason players lose bonus winnings.
Max Cashout Cap
Some bonuses (especially no-deposit bonuses) limit the maximum withdrawable amount. A €10 no-deposit bonus with 50× wagering and €100 max cashout means even a €500 balance after clearing only returns €100. This cap fundamentally changes the EV calculation.
Time Limit / Expiry
Wagering requirements typically expire in 7–30 days. If the timer runs out before you clear, the bonus and any winnings from it are forfeited. At high WR levels (50×+), the time pressure makes clearing nearly impossible at responsible bet sizes — you would need to play intensively every day.
Excluded Games / Providers
Certain slots or entire providers may be excluded from wagering entirely — bets placed on them don’t count. Some exclusion lists are buried deep in the terms. Always check before you start playing. Bets on excluded games drain your balance without making progress on clearing.

How Sticky vs Non-Sticky Affects Wagering Requirements
The sticky vs non-sticky distinction changes the fundamental clearing logic and directly affects how wagering requirements work in practice.
| Type | How It Works During Wagering | Impact on Wagering Requirements |
|---|---|---|
| Non-sticky (forfeit/parachute) | Real money is used first. Bonus is only activated if real money is lost. You can withdraw real-money winnings at any time — the bonus is simply forfeited. | Best for players. You can win with real money and walk away without clearing. The bonus acts as a safety net, not a trap. |
| Sticky (standard) | Bonus and deposit are combined. All play counts toward wagering. Cannot withdraw any winnings until wagering is fully cleared. | Locks all funds until WR is met. No exit option. If you hit a big win early, you must continue wagering to access it. |
Wagering requirements explained most clearly with this rule: If a bonus is non-sticky, the wagering requirement matters less — because you can withdraw real-money winnings without clearing. If a bonus is sticky, the wagering requirement is the entire game — you cannot access any funds until it is complete. Always check sticky/non-sticky status before evaluating the WR multiplier. A 50× non-sticky bonus can be better than a 25× sticky bonus because you have an exit. Sticky vs Non-Sticky Bonuses covers the full comparison.
How to Evaluate Any Bonus Using Wagering Requirements
The 6-Step Bonus Evaluation Framework
Step 1 — Identify the wagering base. Bonus-only or deposit+bonus? This determines the total required wagering. If D+B, the real workload is dramatically higher.
Step 2 — Calculate total required wagering. Base × multiplier. Use the Wager Bonus Calculator for instant computation.
Step 3 — Check the RTP at your casino. Not the game’s published max RTP — the RTP running at your specific operator. Check the game info panel. The difference between 96% and 92% doubles the clearing cost.
Step 4 — Calculate expected loss. Total wagering × (1 − RTP). If this exceeds the bonus value, the bonus is mathematically negative — you are paying more to clear it than it gives you.
Step 5 — Check the hidden terms. Max bet rule, max cashout cap, game contribution, time limit, excluded games. Any of these can invalidate the calculation from Steps 1–4.
Step 6 — Check sticky vs non-sticky. Non-sticky gives you an exit option. Sticky locks you in. This changes the risk profile entirely.

Frequently Asked Questions — Wagering Requirements Explained
What are wagering requirements in casinos?
Wagering requirements are the total amount of money you must bet before bonus funds or bonus winnings become withdrawable. If a €100 bonus has 35× wagering (bonus-only), you must place €3,500 in total bets before the bonus converts to real money. The house edge on those bets is the real cost of the “free” bonus.
Is 35× wagering good or bad?
At 96% RTP with bonus-only wagering, 35× is mathematically negative — the expected clearing cost (~€140 on a €100 bonus) exceeds the bonus value. The break-even point at 96% RTP is approximately 25×. Below 25× is positive value. Above 25× is negative. The Wager Bonus Calculator computes the exact value for any combination.
What is the difference between bonus-only and deposit+bonus wagering?
Bonus-only applies the multiplier to the bonus amount only. Deposit+bonus applies it to both your deposit and the bonus combined — doubling the required wagering at the same multiplier. A 35× bonus-only on €100 deposit + €100 bonus = €3,500 wagering. The same 35× as deposit+bonus = €7,000 wagering. Full comparison here.
Do table games count toward wagering requirements?
Usually at a reduced rate. Slots typically contribute 100%, while blackjack and roulette contribute 10–20%. Some games contribute 0%. At 10% contribution, a 35× requirement becomes an effective 350× on that game. Game Contribution Rates covers this in detail.
Are no-wagering bonuses real?
Yes — some casinos offer 0× wagering on cashback or certain promotions. These have genuine positive value since there is no clearing cost. However, they often come with other restrictions: max cashout caps, game exclusions, or time limits. Always read the full terms, not just the wagering number.
What happens if I bet more than the max bet during wagering?
Most casinos can void all bonus winnings and remaining bonus balance. Some enforce this automatically; others check at withdrawal time. The max bet rule is the most common reason players lose legitimate bonus winnings. Check the cap before you play — it is typically €5–€6 per spin.
How does sticky vs non-sticky affect wagering requirements?
Non-sticky bonuses let you withdraw real-money winnings at any time — the bonus is forfeited. This means wagering requirements matter less because you have an exit. Sticky bonuses lock all funds until wagering is complete — the WR is the entire game. Always check this before evaluating the multiplier.
How do I calculate if a bonus is worth claiming?
Calculate: (base × multiplier) × (1 − RTP) = expected cost. Compare to the bonus value. If cost > bonus, skip it. The Wager Bonus Calculator does this automatically. Also check max bet, max cashout, game contribution, sticky/non-sticky, and time limit.
