The wager bonus calculator below tells you the one number that matters before you claim any casino bonus: what it actually costs. Every bonus headline — “100% up to €500!” — hides a wagering requirement that creates a real mathematical cost via the house edge. This calculator computes the total required turnover, the expected loss during clearing, and the net value of the bonus — so you can see whether the “free” money is genuinely valuable or whether it costs more to clear than it gives you. Enter the bonus amount, the wagering multiplier, the RTP of the game you plan to play, and your average bet size. The wager bonus calculator does the rest.
Wager Bonus Calculator — What It Computes
How to Use the Wager Bonus Calculator
Step 1: Enter the bonus amount (e.g., €100).
Step 2: Enter the wagering multiplier (e.g., 35×). Check whether it is bonus-only or deposit+bonus — this dramatically changes the total turnover.
Step 3: Enter the RTP of the game you plan to play (check the game info panel at your specific casino — not the studio’s published maximum).
Step 4: Enter your average bet size.
Step 5: If you have already started playing, enter the amount wagered so far to see remaining turnover and progress.
Read the result: If the net value is positive, the bonus is mathematically worth claiming. If it is negative, the clearing cost exceeds the bonus value — you would be better off playing without it.

Run these through the wager bonus calculator above to verify the math matches — then swap in your own numbers.
| Scenario | Bonus | WR | Base | RTP | Total Turnover | Expected Loss | Net Value | Verdict |
|---|---|---|---|---|---|---|---|---|
| Low WR, bonus-only | €100 | 15× | Bonus | 96% | €1,500 | €60 | +€40 | Claim — positive EV |
| Standard welcome bonus | €100 | 35× | Bonus | 96% | €3,500 | €140 | −€40 | Skip — costs more than it gives |
| Same bonus, lower RTP | €100 | 35× | Bonus | 92% | €3,500 | €280 | −€180 | Avoid — catastrophically negative |
| D+B wagering | €100 | 35× | D+B | 96% | €7,000 | €280 | −€180 | Avoid — double the workload of bonus-only |
| No wagering cashback | €50 | 0× | — | — | €0 | €0 | +€50 | Always claim — pure value |
| No-deposit bonus | €10 | 50× | Bonus | 96% | €500 | €20 | −€10 | Marginal — risk-free since no deposit, but near-zero EV |
Total turnover = Base amount × WR multiplier
Expected loss = Total turnover × (1 − RTP)
Net value = Bonus amount − Expected loss
Break-even point (bonus-only, 96% RTP): 25×
Below 25× = positive value → claim
Above 25× = negative value → the bonus costs more than it gives
At 94% RTP: break-even drops to ~16.7×
At 92% RTP: break-even drops to ~12.5×
Wager Bonus Calculator: What Changes the Result Most
Four variables drive the wager bonus calculator output. Knowing which one matters most in each situation prevents costly mistakes.
1. Wagering Base (Biggest Impact)
The difference between bonus-only and deposit+bonus wagering doubles your total turnover at the same multiplier. This is the single most impactful variable. Always identify the base before entering anything else into the wager bonus calculator. D+B at 35× = bonus-only at 70× in terms of real workload.
2. RTP at Your Specific Casino
The RTP you enter must be the RTP running at your casino, not the studio’s published maximum. A game running at 92% instead of 96% doubles the house edge — and doubles the expected loss during clearing. Check the game info panel. How Slot Features Affect RTP explains why the same game runs at different RTPs on different casinos.
3. Game Contribution
If you play a game with 10% contribution, your effective wagering multiplier is 10× higher. A 35× requirement on a 10% contribution game = 350× effective turnover. The wager bonus calculator assumes 100% contribution (slots). If playing table games, multiply the result by (100 ÷ contribution %).
4. Sticky vs Non-Sticky
A non-sticky bonus lets you withdraw real-money wins before clearing — meaning the WR may never apply. The wager bonus calculator shows the worst-case cost (full clearing). With non-sticky, your actual expected cost is lower because you might exit before entering the bonus phase.
Wager Bonus Calculator: When to Skip a Bonus Entirely
| Signal | What the Wager Bonus Calculator Shows | Decision |
|---|---|---|
| Net value is negative | Expected loss exceeds bonus amount | Skip — play without a bonus |
| Turnover > €5,000 on €100 bonus | 50×+ effective wagering | Skip — cost is disproportionate to value |
| Spins needed > 5,000 at your bet size | Multiple hours of pure clearing grind | Questionable — is the time cost worth it? |
| RTP at your casino is < 94% | Break-even drops below 17× WR | Most bonuses become negative — recalculate carefully |
| D+B wagering at 30×+ | Equivalent to 60×+ bonus-only | Almost certainly negative — verify before claiming |
The hidden terms the wager bonus calculator cannot check for you: Max bet rules (exceeding the cap voids all winnings), max cashout caps (limit what you can withdraw regardless of balance), time limits (bonus expires before you can clear), and excluded games (bets that don’t count toward wagering). The calculator computes the mathematical cost — but these terms can invalidate the result entirely. Always read the full T&Cs. The Casino Bonus Terms Scanner checks all of these for 35+ casinos.
Wager Bonus Calculator: Comparing Multiple Offers
The most powerful use of the wager bonus calculator is comparing offers side by side. Run each bonus through the calculator, note the net value, and pick the one with the highest (or least negative) result. Here is how three typical offers compare.
| Offer | Bonus | WR | Base | Net Value (96% RTP) | Rank |
|---|---|---|---|---|---|
| Casino A | €200 | 20× | Bonus-only | +€40 | Best — positive EV |
| Casino B | €300 | 40× | Bonus-only | −€180 | Worst — headline looks bigger, costs more |
| Casino C | €100 | 25× | Bonus-only | €0 | Break-even — marginal value |
The counterintuitive result: Casino B’s €300 bonus looks best by headline. The wager bonus calculator reveals it is the worst offer by a wide margin — €180 in expected losses during clearing. Casino A’s smaller €200 bonus at 20× is the only offer with positive expected value. The wager bonus calculator replaces marketing intuition with math. Wagering Requirements Explained covers the full formula and break-even analysis.

Frequently Asked Questions — Wager Bonus Calculator
What does the wager bonus calculator compute?
The wager bonus calculator computes total required turnover (bonus × WR), expected loss during clearing (turnover × house edge), net bonus value (bonus minus expected loss), remaining turnover if you have already started, and estimated spins needed at your bet size. It tells you whether a bonus is mathematically worth claiming.
How do I know if a bonus is worth claiming?
Enter the numbers into the wager bonus calculator. If the net value is positive, the bonus gives you more than it costs to clear — claim it. If the net value is negative, the clearing cost exceeds the bonus value — skip it and play without a bonus. At 96% RTP with bonus-only wagering, the break-even point is approximately 25×.
Why is the expected value of most bonuses negative?
Because the house edge takes a percentage of every bet during clearing. A 35× bonus-only WR at 96% RTP requires €3,500 in turnover on a €100 bonus — and the 4% house edge costs €140, which exceeds the €100 bonus value. Wagering Requirements Explained covers the full math.
What RTP should I enter in the wager bonus calculator?
The RTP running at your specific casino — not the studio’s published maximum. Check the game info panel in the slot you plan to play. Many casinos run reduced RTP configurations (94% or 92%), which doubles or triples the clearing cost. How Slot Features Affect RTP explains why the same game runs at different RTPs.
Does the calculator work for deposit+bonus wagering?
Yes — enter the combined base (deposit + bonus) as the bonus amount and the multiplier as stated. For example, €100 deposit + €100 bonus at 35× D+B = enter €200 as the base and 35× as the multiplier. The calculator will show €7,000 total turnover. Bonus Only vs D+B explains the difference.
What about sticky vs non-sticky bonuses?
The wager bonus calculator shows the full clearing cost — which applies to sticky bonuses (no exit option). For non-sticky bonuses, the actual expected cost is lower because ~40–50% of the time you win during the real-money phase and withdraw without clearing. The calculator shows the worst case.
Can I use the wager bonus calculator for free spins bonuses?
Yes — if the free spins have wagering requirements on winnings. Enter the estimated winnings from the spins as the “bonus amount” and the WR multiplier. For example, 50 free spins producing ~€10 in winnings with 35× WR = enter €10 and 35×. The calculator will show whether the expected clearing cost exceeds the winnings.
What terms can the wager bonus calculator not account for?
Max bet rules (can void all winnings if breached), max cashout caps (limit withdrawable amount), time limits (bonus expires before clearing), excluded games (bets that don’t count), and game contribution rates (reduce effective progress). Always read the full T&Cs. The Casino Bonus Terms Scanner checks all of these automatically.
