A casino bonus calculator helps you quickly see the full picture of an online casino promo. Most bonuses require you to do a bit of math to truly see the fill wagering requirements, and our calculator simplifies that process.
Use this tool to find the wagering requirements based on your deposit amount, the rollover, and, if you have the date, the game contribution rates.
How to Use the Wagering Requirements and Bonus Calculator
To use the calculator, input your deposit amount, the deposit match (or none if it’s a free-play bonus), and the playthrough/rollover stated in the bonus.
Optionally, you can also include the game contribution rate to get a better idea of how much you have to wager to clear the promo terms.
You’ll be given the total bonus amount, your bankroll, as well as the amount of playthrough you’ll have to satisfy to complete the bonus requirements.
Where to Find Casino Bonus DetailsWhere to Find Casino Bonus Details
To find the data for this calculator, you have to read the terms and conditions of the bonus you’re testing (this is good practice anyways).
As an example, here’s a headline bonus from Las Atlantis:

By reading the terms and conditions attached to this promo, you can see the:
- Minimum deposit required for each deposit method
- Wagering requirements and application (deposit + bonus)
- Max bet and max payout
To find the game contribution rates, you often have to look in the expanded Terms and Conditions, linked in the website’s footer. At Las Atlantis, the game contribution rates are stated in the “General Bonus Terms” section of the T&C. They are:
- Slots, Keno, Scratch Cards – 100%.
- Card games (BlackJack, Multihand Video Poker, Video Poker, Tri Card Poker) – 20%
If you have trouble finding the complete bonus terms or wagering contribution rates, try searching the site’s Help Center or FAQ page. As a last resort, you can contact customer support.
However, if the information isn’t readily available, that’s a red flag that the casino doesn’t take players seriously. Bonus terms should be clear and easy to find.
Understanding Wagering RequirementsUnderstanding Wagering Requirements
Online casinos don’t give away free money (mostly), and each bonus comes with a wagering requirement, rollover, or playthrough.
The wagering requirement is presented as a multiplier, such as 30x. This multiplied by the bonus funds is the amount of money you have to spend to be able to request a withdrawal.
For example, if you deposit $50 to claim a 100% deposit match with 25x wagering requirements on deposit + bonus, you would need to wager $2,500 before the casino lets you request a withdrawal.
Bonus vs Deposit + Bonus Requirements
Casino bonus wagering requirements either come attached to just the bonus funds, or to the deposit and the bonus funds combined. Deposit + bonus is the most common, and it really compounds how much you’ll have to spend to clear the bonus terms.
For example, a deposit of $50 at 30x wagering requirements will need $1,500 worth of playthrough. But, a $50 deposit plus a $50 bonus at 30x require $3,000 of playthrough.
Good vs Bad Wagering Requirements
Not all casinos offer the same wagering requirements. In fact, some bonuses at the same casino come with different terms. Crypto bonuses often come with higher wagering requirements than bonuses funded with fiat methods.
Here’s a quick look at the different levels of wagering requirements we’ve seen across online casinos and sportsbooks.
| Rollover Range | Nerd Verdict1 of 2 | Explanation2 of 2 |
|---|---|---|
| 1x | Very Good | 1x is a simple playthrough of the funds you deposited, and is an anti-money laundering rule all reputable casinos follow. |
| 5x-10x | Good | Sports betting bonuses typically have rollover in this range, and some rare casino bonuses. At low deposit amounts, this is a reasonable rollover. |
| 15x-25x | Good | 20x is a good rate for casino bonuses, and a select few sites have such low rollover. This is a bit high for a sports promo, though. |
| 30x – 40x | Okay | This is the industry average for rollover, with the most casinos offering bonuses with this range. |
| 45x-60x | Bad | Bonuses in this range tend to be no-deposit promos, which is understandable, but the range is still bad for any kind of value. |
| 65x and above | Very Bad | It doesn’t matter what kind of promo you’re claiming, with wagering this high it’s unlikely you’ll ever accomplish the requirements. |
Understanding Game Contribution Rates
Casino games contribute differently to the bonus wagering requirements. Slots, keno, plinko, and other casual games usually contribute 100%. Games that require more skill or have a lower house edge, such as blackjack, video poker, and baccarat, often contribute anywhere from 10-30%.
Example:
You claimed a casino bonus and now have $1,000 worth of rollover to satisfy before you can cash out.
If you wager $100 on slots games at a 100% contribution rate, that contributes $100 toward your rollover ($1,000 – $100 = $900 remaining).
If you wager $100 on blackjack at 20% contribution rate, that contributes $20 toward your rollover ($1,000 – $20 = $980 remaining).
You’re getting a trade off here: you can reasonably expect to win more money playing blackjack, but you aren’t making as much progress on your rollover. Slots will help you satisfy rollover faster, but you are unlikely to make as much without hitting a jackpot.
Nerd Tip: If you have a lot of rollover, focus on building a solid bankroll with blackjack and other profitable games. Then, play high RTP slot games to satisfy the rest of your rollover.
Responsible Gambling
Gambling habits can easily spiral out of control, especially if you feel forced to spend more and more to satisfy bonus wagering requirements.
If you feel your gambling habits are becoming a problem, don’t hesitate to find responsible gambling resources and reach out for help.

Use the Bonus Calculator to Make Good Promo Decisions
Don’t fall prey to casino marketing efforts. Claim promotions that shake out to be valuable for you as a player.
If you’re playing casually, anything with a 30x+ rollover will be difficult to achieve, especially if the casino imposes a strict time limit.
Make sure you read the bonus terms and conditions in full before claiming a promotion.
