Casino bonuses come in many shapes and sizes — from modest 50 percent matches to massive 300 percent welcome packages. Each one offers real value, but the way that value plays out depends on the wagering requirement attached. Use the calculator below to compare any bonuses side by side and see which offer best matches your budget and playing style.
Wagering requirements are one of the most important — and most misunderstood — parts of online casino bonuses. A high-percentage bonus with higher wagering can be excellent for high-volume players, while a smaller bonus with low wagering can be perfect for casual play. This calculator helps you see the full picture: enter the deposit amount, bonus percentage, wagering multiplier, and game RTP for each bonus you are considering, and instantly compare the total wagering volume, projected return after wagering, and overall mathematical value across all offers.
Compare bonuses side by side. See the wagering requirement, projected return, and which offer ranks best based on the math.

How to use this calculator: Enter the deposit amount, bonus percentage, and wagering requirement (WR) for each bonus you're comparing. The calculator shows the total amount you need to bet to clear the bonus, and the mathematical projection based on the game's RTP. Important: These numbers are long-term statistical averages — individual sessions can vary widely. Slots are random, so you may win significantly above the projection, break even, or lose more, depending on game variance and luck.
How to read the results
The calculator shows several key numbers for each bonus. Here is what each one means and how to use them when comparing offers:
Bonus amountThe actual cash value the casino adds on top of your deposit. A 100 percent bonus on a $100 deposit gives you $100 in bonus funds.
Total starting balanceYour deposit plus the bonus. This is what you start playing with.
Total to wagerThe total amount you must bet before the bonus and winnings become withdrawable cash.
Expected returnBased on the game RTP, this is the mathematically projected return across the full wagering period. Higher RTP games and lower wagering requirements both improve this number.
Expected value (EV)Your projected outcome after clearing the bonus. A higher EV means the bonus is mathematically more favorable based on the inputs you entered.
Best value badgeThe bonus with the highest expected value among your inputs is automatically marked. This helps you quickly see which option ranks best for your specific scenario.

Just 10x wagering — one of the lowest on the market. Excellent for players who prefer to clear bonuses quickly.
A wagering requirement (WR) is the number of times you must bet a bonus amount before you can withdraw any winnings. For example, a $100 bonus with 35x wagering means you must place $3,500 in bets before the bonus and any winnings become withdrawable cash.
35x wagering is the industry standard and considered fair. Anything under 30x is genuinely player-friendly, 20x or lower is excellent. Higher wagering levels (40x-50x or above) are common with larger bonus offers and can still be worthwhile depending on the bonus size, RTP, and how much you plan to play.
It means the wagering requirement is calculated only on the bonus amount, not your deposit. This is generally the more favorable structure for players. WR on deposit plus bonus is stricter because you wager both amounts multiplied by the WR number, though it can still be worth it on larger bonuses with attractive terms.
The calculator gives a mathematically accurate expected value based on the RTP you enter and the wagering requirement. Actual results vary because slots are random, but over many sessions results converge toward the calculated expected value.
RTP stands for Return to Player and represents the percentage of all wagered money a game pays back over time. A 96 percent RTP slot returns 96 dollars for every 100 dollars wagered on average. Higher RTP games improve your expected return across the wagering period, which can boost the overall value of a bonus.
Mathematically, bonuses can have positive expected value when you combine low wagering requirements, high RTP games, and bonus-only wagering. Even bonuses with higher wagering can be worthwhile when the bonus amount is large enough or when you enjoy extended playing time. Use the calculator to see exactly where each offer stands based on your inputs.
