What this bonus is worth
Press Calculate to run the numbers.
How it works: we simulate the bonus thousands of times on a slot with the RTP and volatility you chose, betting the same amount each spin until the wagering is done or the balance runs out. Winnings above the max cashout are cut to the cap. It is an estimate, not a promise: real slots and real terms vary.

Wagering Requirements Explained
A wagering requirement, also called playthrough or rollover, is the amount you must bet before bonus money can be withdrawn. It is written as a multiple. On this site "40xb" means 40 times the bonus, so a $25 no deposit bonus with 40xb wagering needs $1,000 of bets before you can cash out. For free spins the multiple usually applies to what the spins win rather than to a fixed bonus amount.
Every bet carries the house edge of the game. On a slot with 96% RTP (return to player), the casino keeps about 4% of everything wagered over time. That is why wagering matters so much: the more you have to bet, the more of the bonus the house edge takes back before you finish.
Max Cashout and Why It Matters
Most no deposit bonuses also have a maximum cashout, the most you can withdraw from the bonus however much you win. If the cap is $100 and you finish the wagering with $400, you keep $100. A low cap limits the upside, so the calculator cuts every result to the cap you enter.
How to Use the Calculator
- Choose a free chip or free spins, and enter the bonus amount or the number of spins and their value.
- Enter the wagering requirement and the max cashout from the bonus terms.
- Set the RTP and volatility of the slot you plan to play, and a bet size below the max bet allowed.
- Press Calculate. On our bonus lists, the "What's it worth?" link under each offer opens the calculator with its terms already filled in.
The result shows how much you need to bet in total, what that betting is expected to cost, your chance of finishing the wagering with money left and the average amount you would cash out. Most no deposit bonuses are worth a few dollars on average, and most players lose the bonus before the wagering is done. That is normal: they are a free way to try a casino, not a way to make money.
Frequently Asked Questions
1. What does 40xb mean in bonus terms?
- It means you must wager 40 times the bonus amount before you can withdraw. A $20 bonus with 40xb wagering needs $800 of bets.
2. Does low or high volatility make a bonus easier to clear?
- Low volatility slots pay small wins often, so your balance lasts longer, but big wins are rare. High volatility slots bust more often but sometimes produce a large win. Try both in the calculator to see how the chance of finishing changes.
3. Is the calculator result guaranteed?
- No. It is an estimate based on a simulated slot with the RTP and volatility you choose. Real games, game weighting and bonus rules vary, so always read the full terms.
4. Can I use it for deposit bonuses?
- It is built for no deposit offers. For deposit bonuses, where wagering often includes your deposit, use the Wizard of Odds bonus calculator linked above.
