Casino Bonus Calculator

At 101RTP, we run 1,000,000 to 10,000,000 wagering simulations per bonus to determine what you can realistically expect to win.

The calculator analyses four critical metrics.

• Expected Value (EV). Your average profit across millions of attempts. A $100 bonus with 40x wagering might show +$70 EV, meaning you'll profit $70 on average long-term.
• Clear Rate. Percentage of successful completions. That same bonus might have 8% Clear Rate (you'll convert it in 8 of 100 attempts).
• Average Win. Typical win when successful, like $2,244 in our example.
• ROI. Profit as percentage of money wagered. Together, these numbers tell you if a bonus is genuinely profitable or cleverly disguised trap.

Wagering (playthrough) determines how many times you must bet your bonus before withdrawing. A $100 bonus with 40x wagering means $4,000 total bets required.

Two types exist: Bonus only (40x on $100 = $4,000 required) and Bonus + Deposit (40x on $100 bonus + $100 deposit = $8,000 required). The latter doubles the workload and typically halves EV. Here's the key: higher wagering doesn't automatically destroy value. Our testing proved bonuses remain positive EV even at 500x wagering on high-volatility slots because your average win when successful increases dramatically.

Let's calculate a real bonus. Offer: 100% match $200, 35x wagering on bonus + deposit, played on Gates of Olympus (96.5% RTP), $5 max bet, no win limit. Total funds: $400. Wagering requirement: 35x $400 = $14,000 total bets. Running this through the calculator with 1,000,000 simulations produces: EV +$52, Clear Rate 9.2%, Average Win $765, ROI 26%. Verdict: positive EV bonus worth claiming. Now add a $1,000 maximum win cap. The calculator recalculates: EV +$18, Clear Rate 9.2%, Average Win $445, ROI 9%. That single restriction slashed EV by 65%, proving why simulation data matters.

Our casino bonus calculator analyses all major bonus types. Here's what is casino bonus wagering for each:

• Welcome Bonus. Match deposit bonuses for new players (typically 100-200%).
• No Deposit Bonus. Free cash or spins without depositing. Small amounts ($10-$50) with high wagering (50-70x).
• Reload Bonus. Deposit match for existing players (25-75%). Lower percentages than welcome offers but often better wagering terms (25-35x).
• Free Spins. Spins on specific slots. Winnings convert to bonus with 30-50x wagering. Calculator evaluates based on slot RTP and volatility.
• Sticky Bonus. Non-withdrawable bonus deducted upon cashout. Calculator automatically reduces EV by 25-40% versus non-sticky equivalents.
• Cashback Bonus. Percentage of losses returned (5-25%). Usually low or no wagering (0-5x). Calculator shows these typically offer excellent value.

The wagering requirements tool considers six critical factors that determine if you'll actually convert bonus to cash:

• Wagering Requirements. The multiplier determining total bets needed. 35x on $100 bonus = $3,500 wagering. Higher numbers reduce completion probability but don't always destroy EV.
• Max Bet Limits. Maximum allowed bet during wagering, typically $5.
• Game Contributions. How much each game type counts. Slots 100%, table games 10-20%, live casino 0-10%.
• Slot Restrictions. High-RTP games often excluded or contributing at 50%. Being forced into 94% RTP slots versus 96.5% options reduces EV by 30-50%.
• Bonus Expiration. Time limit for completing wagering. 24-48 hours forces rushed play. We prefer 7-14 days for strategic session planning.
• Country Restrictions. Some countries excluded from bonuses or face different terms. Always verify your jurisdiction qualifies before depositing.

After wagering 10,000+ bonuses at 101RTP, here's what actually works:

• Pick Bonuses Under 35x. Wagering above 40x significantly reduces completion probability. Our data shows 35x or lower offers the best balance between EV and realistic clear rates.
• Play Slots with High RTP. Target 96.5%+ RTP games. The difference between 96.5% and 94% RTP can reduce your EV by 40-60%.
• Avoid Jackpot Slots. Progressive jackpots typically contribute 0% toward wagering requirements. Playing them wastes time without reducing your wagering total.
• Use Bankroll Management. You need 150-200x your bet size as bankroll for comfortable bonus clearing. With $100 bonus requiring $3,500 wagering, budget for potential dry spells.
• Prefer Non-Sticky Bonuses. These allow full balance withdrawal versus sticky bonuses that deduct the original bonus amount. Non-sticky offers show 25-40% higher EV in our calculations.

Smart alternatives exist.

• Low Wagering Casinos. Some operators offer 10-20x wagering instead of standard 35-40x. These dramatically improve your completion chances.
• Bonus-Free Casinos. Growing number of platforms skip bonuses entirely, offering better base conditions instead: higher cashback percentages (10-25% weekly), faster withdrawal processing (under 24 hours), and no game restrictions.
