Wagering Requirements Calculator — Casino Bonus True Cost

Start by entering the bonus amount — the dollar value of the casino promotion. This is typically a matched deposit bonus (e.g., 100% up to $100) or a no-deposit free chip. Then enter your deposit amount if the casino requires you to wager the deposit alongside the bonus.

Use the Wagering Applies To dropdown to choose whether the requirement applies only to the bonus or to the bonus plus your deposit. This is critical — "35x bonus" and "35x bonus + deposit" are very different obligations. If you deposited $100 and received a $100 bonus, a 35x bonus-only requirement is $3,500 in total bets. A 35x bonus+deposit requirement is $7,000.

Enter the wagering multiplier as shown in the bonus terms (e.g., 35 for "35x wagering"). Then select the game contribution for the game you plan to play. Sportsbooks and casinos typically give slots 100% contribution toward clearing a bonus, while table games like blackjack contribute only 10%, meaning you need to wager 10 times more to meet the same requirement.

The calculator instantly shows the total wagering required, the adjusted amount for your chosen game, the expected loss based on a 3% average house edge, and whether the bonus has positive expected value (EV).

The wagering requirements calculation follows these steps:

1. Base Amount:
   • If bonus only: Base = Bonus Amount
   • If bonus + deposit: Base = Bonus Amount + Deposit Amount
2. Total Wagering Required = Base Amount × Wagering Multiplier
   This is the nominal amount you need to bet at 100% game contribution.
3. Adjusted Wagering Required = Total Wagering Required ÷ (Game Contribution ÷ 100)
   If playing blackjack at 10% contribution, divide by 0.10 — you need to place 10x more actual bets to clear the same requirement.
4. Expected Loss = Adjusted Wagering Required × 0.03
   Using a 3% average house edge as an approximation. Slots typically run 3–8%, while blackjack with perfect basic strategy can be as low as 0.5%.
5. Net EV = Bonus Amount − Expected Loss
   Positive net EV means the bonus is worth claiming in theory.
6. Break-Even Multiplier = (Bonus Amount × Game Contribution ÷ 100) ÷ (Base Amount × 0.03)
   This is the maximum wagering multiplier at which the bonus still has non-negative expected value.

Note: These calculations assume average house edge and do not account for variance, time constraints, or maximum bet restrictions imposed by the casino. Always read the full bonus terms and conditions.

Example 1 — Standard Welcome Bonus (35x, Slots Only)

• Bonus: $100 | Deposit: $100 | Wagering: bonus only
• Multiplier: 35x | Game: Slots (100% contribution)
• Total wagering required: $3,500
• Expected loss at 3% house edge: $105
• Net EV: −$5
• Verdict: Marginally not worth it at a standard casino. However, if the casino has tight slots (5%+ RTP disadvantage), the loss could be significantly higher.

The break-even point for a $100 bonus wagering bonus-only at 100% slots is approximately 33x. Any offer at 33x or below has positive expected value in theory.

Example 2 — Attractive Low-Requirement Bonus (20x)

• Bonus: $200 | Deposit: $200 | Wagering: bonus only
• Multiplier: 20x | Game: Slots (100%)
• Total wagering required: $4,000
• Expected loss: $120
• Net EV: +$80 — worth claiming

A 20x bonus-only requirement on slots is an excellent offer. Bonus hunters and professional bonus clears specifically seek out these low-multiplier promotions.

Example 3 — Trying to Clear with Blackjack (Bad Idea)

• Bonus: $100 | Wagering: 35x bonus only
• Total wagering required: $3,500 (nominal)
• Game: Blackjack at 10% contribution
• Adjusted wagering required: $35,000 in actual blackjack bets
• Expected loss at 3%: $1,050
• Net EV: −$950 — avoid entirely

This is why low-contribution games produce terrible results for bonus clearing. Always check whether your preferred game contributes fully before accepting a bonus.

How Casinos Structure Wagering Requirements

Most online casinos use a tiered contribution system. Slots and instant-win games typically contribute 100%. Video poker might be 20–50%. Table games like blackjack, baccarat, and craps are usually 10% or excluded entirely. Live dealer games often contribute 10%. Some casinos exclude high-RTP slots (above 97%) from qualifying. Always check the specific list of excluded games in the bonus terms.

Time Limits and Forfeit Rules

Wagering requirements usually come with a time limit — commonly 7, 14, or 30 days. If you do not complete the wagering within this window, both the bonus and any winnings from it are forfeited. Factor the time constraint into your decision: a 35x wagering requirement on $100 requires you to place $3,500 in bets. At $5 per spin and roughly 500 spins per hour, that is about 1.4 hours of play — manageable. At $1 per spin it would take seven hours.

Maximum Bet Rules

Nearly all casinos impose a maximum bet while a bonus is active — typically $5 per spin or $10 per hand. Exceeding this limit can result in the bonus being voided, even if you have already completed the wagering. This rule is strictly enforced. Always confirm the maximum bet before depositing.
