If you’ve ever stared at a “35× wagering” line and wondered, “How much do I still need to play through to unlock this bonus?”, the Wager Bonus Calculator gives you the answer in one click. Put in your bonus, the wagering multiple, and what you’ve already wagered; it returns the remaining turnover, your progress %, and—optionally—an estimate of spins left based on your average bet.
This guide reviews the Wager Bonus Calculator in depth: what it does, how it does it, how to use it properly for sticky vs. non-sticky bonuses, pitfalls to avoid (game contribution %, bet caps, time limits), and realistic examples so you can plan your play and protect your bankroll.
TL;DR (Why this tool matters)
- The Wager Bonus Calculator turns “35× on €100” into clear numbers: total target turnover €3,500; if you’ve wagered €2,380, you still have €1,120 left.
- It shows progress percentage and can estimate spins left based on your bet size (e.g., remaining €1,120 at €0.20/spin ≈ 5,600 spins).
- It’s built for real-world terms: currency switcher, instant validation, and a visual progress bar.
- It’s a planning tool, not a guarantee of winnings. Use it to decide if a bonus is worth the time, risk, and bankroll it demands.
Use this free tool to determine exactly how much you need to wager to unlock your bonus funds. Whether you’re a casual player or a seasoned gambler, it helps you plan smarter and avoid surprises.
How to Use the Wager Bonus Calculator
- Select your currency.
- Enter Bonus Amount (e.g., 100).
- Enter Wagering Requirement (e.g., 35 for 35×).
- Enter Amount Already Wagered (if any).
- (Optional) Enter Average Bet / Spin to estimate spins left.
- Click Calculate.
Tip: If your bonus terms specify game contribution %, enter the raw values first, then see the “Advanced scenarios” section of this article to adjust.
Wager-To-Unlock Bonus Calculator
35× on €100 = €3,500 total turnover. Use this to see what’s left to unlock your bonus.
Note: This tool is for guidance only. Always check the casino’s terms (eligible games, contribution %, max cash-out, and time limits) before playing.
What the Wager Bonus Calculator actually calculates
At its core, the tool computes four things:
- Total target turnover
Total turnover = Bonus amount × Wagering multiple
Example: €100 bonus at 35× → €3,500 total turnover. - Completed turnover
Whatever you’ve already wagered on eligible games (as per the bonus terms). - Remaining turnover
Remaining = Total turnover − Completed turnover
The amount you still need to wager before the bonus unlocks or becomes withdrawable. - Progress percentage
Progress % = (Completed ÷ Total) × 100
Optionally, if you add Average Bet / Spin, the calculator estimates how many spins remain:Estimated spins = Remaining ÷ Average bet
This gives you a practical time/effort estimate. If you typically spin at €0.20 and you have €1,120 left, that’s 5,600 spins—useful for pacing your session and budgeting your bankroll.
When to use the Wager Bonus Calculator
- Before claiming a bonus: sanity-check the real cost in time and turnover; compare alternative offers (e.g., 100% up to €100 at 35× vs €50 at 20×).
- While playing: track progress and decide whether continuing is worth it based on time limits, remaining spins, and your bankroll.
- Before a deadline: determine whether you can realistically finish within 24–72 hours or whatever the terms state.
- After a session: log your completed turnover, see what’s left, and avoid over- or under-shooting.
How to use the Wager Bonus Calculator (step-by-step)
- Choose your currency (€, $, £).
- Enter the Bonus Amount (e.g., 100).
- Enter the Wagering Requirement as a number (e.g., 35 for 35×; the tool also accepts “35×”).
- Enter Amount Already Wagered, if any (e.g., 2380).
- Optional: enter Average Bet / Spin for a spins-left estimate.
- Click Calculate.
- Read the Total target turnover, Completed, Remaining, and Progress %. Use the estimate to plan your session.
Worked examples you can sanity-check
Example A — Standard 35× bonus
- Bonus amount: €100
- Wagering multiple: 35×
- Already wagered: €2,380
- Average bet: €0.20 per spin
Results:
- Total target turnover: €100 × 35 = €3,500
- Remaining: €3,500 − €2,380 = €1,120
- Progress: (2,380 ÷ 3,500) × 100 = 68%
- Estimated spins left: €1,120 ÷ €0.20 = 5,600 spins
Example B — Lower multiple but smaller bonus
- Bonus amount: €50
- Wagering multiple: 20×
- Already wagered: €0
Results:
- Total target turnover: €50 × 20 = €1,000
- Remaining: €1,000
- At €0.40/spin → 2,500 spins.
- At €1.00/spin → 1,000 spins.
Observation: Even though the headline bonus is smaller, the total turnover is much more achievable if you’re time-limited.
Example C — High multiple, high bet size
- Bonus amount: €200
- Wagering multiple: 45×
- Already wagered: €4,000
- Average bet: €1.00
Results:
- Total target turnover: €200 × 45 = €9,000
- Remaining: €9,000 − €4,000 = €5,000
- Progress: 44%
- Spins left at €1/spin: 5,000
- At €2/spin: 2,500 spins.
Observation: Larger bonuses with high multiples can be deceptively demanding. Use the Wager Bonus Calculator upfront to judge feasibility.
Why a Wager Bonus Calculator beats mental math (and spreadsheets)
- Avoids unit mistakes: people often confuse 35× of bonus vs 35× of bonus + deposit. This tool focuses on the common “bonus × multiple” case to stay clear and consistent.
- Shows progress instantly: the progress bar helps you see pacing at a glance.
- Estimates spins: mental math rarely translates turnover to spins; here you can input an exact bet size.
- Reduces sunk-cost errors: seeing that 70% remains with 12 hours left makes it easier to stop rather than chase.
What the calculator assumes (and how to adjust)
To keep the Wager Bonus Calculator fast and broadly useful, it assumes:
- Wagering is expressed as a multiple of the bonus amount (e.g., 35× bonus).
- Eligible games contribute 100% to turnover unless you manually adjust.
- There’s no max cash-out cap applied to the calculation itself (though your bonus may have one).
- You’re tracking non-sticky or “cashable after wagering” structures unless noted otherwise.
You can still handle real-world wrinkles. Here’s how.
Advanced scenarios and real-world terms
1) Game contribution percentages
Some casinos specify different contribution rates:
- Slots: 100%
- Live casino: 10%–20%
- Table games: often 0%–10%
How to adjust: Calculate your remaining turnover using 100%, then divide by the contribution rate of the game you’ll play.
Example: Remaining turnover €1,000 but your chosen game contributes 50%
- Effective turnover you must play on that game = €1,000 ÷ 0.5 = €2,000 actual spins/turnover.
2) Deposit + bonus wagering
Occasionally, the multiple applies to deposit + bonus.
If the terms say “35× (D+B)” and you deposited €100 and got a €100 bonus, the base for the multiple is €200.
- Total target turnover:
(Deposit + Bonus) × Multiple - With €100 deposit + €100 bonus at 35×:
(100 + 100) × 35 = €7,000.
You can still use the Wager Bonus Calculator by entering €200 as the “bonus amount” to replicate this structure, then multiply by 35×. The math works because the base figure is what matters.
3) Sticky vs. non-sticky (parachute/forfeitable) bonuses
- Non-sticky (cashable): Your real money is blended with bonus money; meet wagering to cash out. The calculator fits this perfectly because it’s all about turnover to unlock.
- Sticky (non-cashable): The bonus itself isn’t withdrawable; you can withdraw winnings after wagering, but the bonus is removed at the end. The remaining turnover math is the same, but the value of the bonus differs since you never withdraw the principal bonus.
4) Bet caps and game restrictions
Many bonuses cap max bet per spin (e.g., €5) and exclude some features (bonus buys, certain high-volatility slots). This doesn’t change the turnover math, but it does change how fast you can complete wagering.
- If bet cap is €5 and you have €5,000 remaining, even at 100% contribution, that’s at least 1,000 spins.
- If the slot contributes 50%, you’d need 2,000 spins at the same bet cap.
5) Time limits
Bonuses often expire in 24, 48, or 72 hours. Use the tool’s spins estimate to decide if you can finish in time without rushing your bankroll.
- Example: 5,600 spins left at 500 spins/hour → ~11.2 hours of play. Spread over 3 days? That’s ~3.7 hours/day.
6) RTP, volatility, and bankroll planning
The Wager Bonus Calculator isn’t a profit predictor—it’s a workload predictor. However, wagering volume interacts with expected losses:
- RTP: A slot with 96% RTP implies a 4% house edge on turnover. A €3,500 turnover carries an expected loss of ~€140 in the long run (4% of €3,500).
- Volatility: High-volatility slots can swing widely. Your actual outcome may be far from expectation; plan a buffer.
- Bankroll: If your average bet is €0.40 and you aim to spin 5,000 times, your total staked will be ~€2,000. Make sure your bankroll and bet size fit your risk tolerance and time limit.
Interpreting the results
- If Remaining turnover is high relative to your time limit, consider dropping the bonus rather than over-spinning under pressure.
- If Progress % is >80% and you’re within the time window, finishing may be optimal—just don’t break bet caps or game rules.
- If Estimated spins is much higher than your usual session length, reduce the average bet or spread sessions across days (if permitted).

Strategy advice: making smarter choices with the Wager Bonus Calculator
- Compare offers by total turnover
A 100% up to €100 at 35× requires €3,500 turnover. A 50% up to €50 at 20× requires €1,000. If you can’t comfortably play through €3,500 within the time limit, the second offer may be more realistic—even if the headline looks smaller. - Pick games with 100% contribution
If allowed, prioritize games that contribute fully to wagering to avoid doubling the real workload. Keep an eye on RTP and volatility. - Size bets to your time window
If the calculator shows 6,000 spins left and you can do ~600 spins/hour, that’s ten hours. Increase your average bet or pass on the bonus if time-limited—but never exceed the max bet cap in the terms. - Track progress every session
Enter your updated “Already wagered” after each play session. If the remaining number isn’t shrinking fast enough, reassess before you’re up against a deadline. - Mind the expected loss
Roughly, Expected Loss ≈ House Edge × Turnover. If RTP is 96% (4% house edge) and your turnover goal is €3,500, the long-run expected loss is €140. That doesn’t mean you will lose €140—variance is real—but it’s a responsible planning benchmark. - Know when to walk
If you’re behind schedule or the remaining turnover is too large, the calculator gives you the clarity to forfeit the bonus rather than chase losses out of commitment bias.
Bonus Math Cheat Sheet
- Total target turnover = Bonus amount × Wagering multiple
- Remaining turnover = Total target − Already wagered
- Progress % = (Already wagered ÷ Total target) × 100
- Estimated spins (optional) = Remaining ÷ Average bet
| Scenario | Input | Result |
|---|---|---|
| Standard bonus | €100 at 35× | Total turnover €3,500 |
| Deposit + bonus wagering | (€100 + €100) × 35× | Total turnover €7,000 |
| 50% contribution game | Remaining €1,000 | Play €2,000 turnover on that game |
| Spins estimate | Remaining €1,120 at €0.20/spin | 5,600 spins |
Reminder: Always confirm contribution %, excluded games, max bet, max cash-out, and time limits in the bonus terms.
Common pitfalls the Wager Bonus Calculator helps you avoid
- Confusing 35× bonus vs 35× deposit + bonus
Always read how the wagering base is defined. If it’s (D+B), compute on the sum. - Ignoring contribution rates
If a game contributes 20%, you’ll need 5× more actual turnover there. Don’t discover this at 2 a.m. on deadline day. - Overlooking bet caps
Spamming €10 spins when the max is €5 can void your bonus. Use the spins estimate to plan within caps. - Underestimating time
5,000–10,000 spins is a lot. Estimate your spins/hour and cross-check with your calendar. - Expecting guaranteed profit
Bonuses lower the effective house edge but don’t eliminate it. The calculator guides workload, not outcome.
Who benefits most from the Wager Bonus Calculator
- Everyday players who want to avoid ugly surprises.
- Streamers who need to plan session length and keep to responsible play.
- Reviewers and affiliates who want transparent, math-first bonus explanations.
- Compliance teams who prefer tools that nudge users to read and respect the terms.
FAQ – Wager Bonus calculator
What’s the difference between “bonus × multiple” and “(deposit + bonus) × multiple”?
Some casinos apply the wagering multiple only to the bonus amount; others apply it to the sum of deposit and bonus. The Wager Bonus Calculator is set up for the bonus × multiple case, but you can make it work for (D+B) by entering the combined number as your “bonus” and then applying the multiple. The math is identical once the base is correct.
How do I account for game contribution percentages?
Compute your remaining turnover normally, then divide it by the contribution rate. If you have €1,200 remaining and will play a game that contributes 50%, plan for €2,400 in actual turnover on that game.
Does the Wager Bonus Calculator tell me how much I’ll win?
No—it’s a planning tool for turnover and workload. Your results depend on RTP, volatility, and luck. Treat the expected-loss heuristic (house edge × turnover) as a budgeting guide, not a prediction.
Can I use it for sticky bonuses?
Yes. The remaining turnover math is the same. Just remember that with sticky bonuses, the bonus amount itself usually isn’t withdrawable, even after wagering.
What if my bonus has a max bet cap?
Respect it. The calculator can’t know your cap, but the spins-left estimate lets you see how long completion will take at legal bet sizes.
Is there a way to track sessions?
Use the “Already wagered” field as a running total. After each session, update it; the remaining number and progress bar will adjust instantly.
Why do I sometimes see huge “spins left” numbers?
Large remaining turnover at small average bets naturally produces big spin counts. Consider increasing your average bet (if within the cap) or passing on the bonus.
Why doesn’t the calculator include excluded games or time limits?
Those are terms, not math. The calculator assumes eligible play. Always read the terms and conditions for exclusions, contribution %, time windows, max bet, and max cash-out.
Responsible gambling reminder
The Wager Bonus Calculator is a clarity tool. It doesn’t change the math of the game. Set limits, respect time windows, never chase losses, and stop when the fun stops. If the remaining turnover or estimated spins look unrealistic for your time or bankroll, skip the bonus. That is a winning decision too.
Conclusion
Bonuses can be great—but only if you understand their true cost in turnover and time. The Wager Bonus Calculator turns ambiguous “35× wagering” lines into clear, actionable numbers. With progress %, remaining turnover, and spins-left estimates, you can plan your sessions, choose better offers, avoid last-minute panic, and play more responsibly.
Use it before you claim, during your sessions, and when deciding whether to finish or walk away. Clarity saves time, money, and headaches.
