A wagering requirement is the total amount you must bet before bonus money converts into withdrawable cash — and it is always a multiple of the bonus. A €10 bonus at 40x means €400 in bets. Not €400 lost — €400 staked. Every casino bonus you will ever see, from a €10 no-deposit credit to a $1,000 welcome match, lives or dies by this number, so five minutes here saves real disappointment later.
The Basic Formula
Bonus amount × multiplier = required turnover.
Your bets accumulate toward the target; wins and losses along the way are irrelevant to the counter. Stake €0.50, and the counter moves €0.50 closer, whatever the spin returns. When the counter hits the target, remaining bonus winnings become real — subject to any cashout cap. Casinos display the live progress in your account’s bonus section; make checking it a habit, because that bar is the only number the cashier will honour.
Worked examples across common offer types:
| Offer | Wagering | Required turnover | In practice |
|---|---|---|---|
| €5 no-deposit cash | 30x | €150 | 1,500 spins at €0.10 |
| €10 no-deposit cash | 40x | €400 | 4,000 spins at €0.10 |
| €10 no-deposit cash | 60x | €600 | 6,000 spins at €0.10 |
| €300 deposit bonus | 35x (bonus only) | €10,500 | 10,500 spins at €1 |
| €100 dep. + €100 bonus | 35x (deposit + bonus) | €7,000 | on a €200 start |
For context: across the no-deposit market, requirements run from 5x to 60x, with 35x–50x the most common band. Anything at 20x or below is genuinely soft; anything above 50x needs a big cashout cap to be worth your evening.
Convert turnover into time and the numbers get honest fast. €400 at €0.10 spins is 4,000 button presses; even at a brisk few hundred spins an hour, that’s a multi-hour commitment spread across the offer’s validity window. Wagering is measured in euros but paid in evenings — factor both currencies before deciding an offer is “free”.
Free Spins Winnings Wager Too
A common blind spot: free-spin bonuses don’t skip wagering, they relocate it. The spins themselves are just delivery — whatever they win lands as bonus funds, and the requirement applies to those winnings. Win €6 from a 45x spin pack and your target is €270 of turnover before the €6 (capped) becomes real.
That creates an asymmetry worth knowing. With cash, the wagering base is fixed — €10 at 40x is €400, full stop. With spins, the base scales with your luck: win little and the requirement is small (but so is the prize); win big and the turnover mountain grows with it. Neither structure is a trick, but they behave differently, and the cash vs free spins guide plays out which suits whom.
Bonus-Only vs Deposit + Bonus: The Same Number, Twice the Work
The multiplier means nothing until you know what it multiplies. “35x bonus” on a €100 bonus is €3,500 of turnover. “35x deposit + bonus” on a €100/€100 pair is €7,000 — double the workload behind an identical-looking headline.
Casinos state the base in the terms, usually in one dry sentence players skip. Don’t skip it. Between two offers with the same advertised multiplier, the wagering base is often the entire difference in value.
Game Weighting: Not Every Bet Counts Fully
Casinos weight games by how much they contribute to the counter. The typical pattern — always confirm in the specific casino’s terms:
| Game type | Typical contribution |
|---|---|
| Slots | 100% |
| Table games (roulette, blackjack) | 0–10% |
| Live dealer | 0–10% |
| Selected high-RTP slots / jackpots | often excluded |
The arithmetic bites hard. A €50 blackjack hand at 10% weighting adds just €5 to your counter — meaning a €400 requirement cleared at blackjack demands €4,000 in actual bets. Excluded games are worse: bets may add nothing, and at some casinos playing a restricted title during wagering is grounds to void bonus winnings entirely. Wagering on slots is not a recommendation; it is simply how the math is designed.
The Max Bet Trap
Nearly every bonus caps your stake while wagering is active — commonly a low single-digit figure per spin. The cap exists to stop players from gambling the whole bonus on a few large bets, and the penalty for breaching it is brutal: terms typically allow the casino to void all bonus winnings, even if the oversized bet lost.
Three habits keep you safe. Find the number in the bonus terms before your first spin. Watch for features that raise the effective stake — bonus-buy options and some ante modes can multiply your bet past the cap in one click. And when in doubt, bet smaller: nothing in the wagering formula rewards big stakes; €400 of turnover counts the same at €0.20 as at €5.
The Fine Print Around the Number
- Expiry. Requirements run on a clock — 7 to 30 days is typical. Unfinished wagering at the deadline forfeits the bonus and its winnings.
- Cashout caps. No-deposit offers cap withdrawable winnings (typically €25–€50 across the market) regardless of how far past the requirement you run. Details in our no deposit cash bonus guide.
- Pattern-play clauses. Many casinos reserve action against “bonus abuse” — minimal-risk betting, stake manipulation around the requirement, duplicate accounts. Ordinary play doesn’t trigger these; systems designed to trigger them get accounts closed.
- One offer at a time. Most casinos queue bonuses; bets clear the active one first. Check before stacking.
What Clearing Actually Costs: The Honest Arithmetic
Here is the calculation bonus pages rarely show you. Turnover has a theoretical price: turnover × house edge. Clearing €400 on a 96% RTP slot costs about €16 in expected losses — more than the €10 bonus it unlocks. At 20x (€200 of turnover), the same math costs about €8, and the bonus is theoretically worth a couple of euros.
Two honest conclusions follow. First, most high-multiplier bonuses are designed so the average player does not finish with a profit — that is why casinos can afford them. Second, variance, not the average, decides any single attempt: some players clear the requirement early and cash the cap; more run dry before the counter fills. Treat wagering as the price tag of entertainment, never as a work contract with a payout at the end.
RTP drives that cost estimate, and RTP varies more than most players realise — same slot, different builds at different casinos. Our RTP and volatility guide shows how to check the live figure before you commit turnover to a game.
Common Misreadings That Cost Money
- “Only losses count.” No — every stake counts, win or lose. The counter tracks turnover, not results.
- “A big win resets my wagering.” It doesn’t. Winning €200 mid-requirement changes your balance, not your remaining turnover.
- “I can finish wagering on any game.” Weighting and exclusion lists say otherwise; the wrong game can contribute 0% — or void the bonus.
- “Bonus and real money are one pot.” Casinos track them separately, and which balance your bets draw from first varies by casino. Check before mixing deposited money with an active bonus.
- “Close enough will pay out.” 99% complete is 0% complete at the cashier. The progress bar is binary the day you withdraw.
Each of these appears in real complaint threads weekly, and every one is preventable by reading the bonus terms — a five-minute job that outperforms any playing “system” ever sold.
How to Read Any Bonus in 60 Seconds
- Multiplier and base — 35x on what, exactly?
- Turnover in euros — do the multiplication yourself.
- Cap — the most you can win from the exercise.
- Max bet — the number that voids winnings.
- Clock and games — how long, and does your game count at 100%?
Run those five checks on any offer — the €10 cash bonuses, a welcome match, anything — and you will know its real value before you click. When you’re ready to cash out, the withdrawal guide covers the final stretch: verification, processing times and the rejection reasons that actually get cited.
Play Responsibly
A wagering requirement is a spending schedule in disguise — €400 of turnover is real play with real house edge, whatever the bonus banner says. Decide what the session may cost before you claim, set deposit limits, and never chase a counter with money you need. Free, confidential support: BeGambleAware, GamCare, Gambling Therapy.
