Casino Bonus Calculator Example

Deposit Bonus Calculator

Deposit bonuses are exactly what they sound like—bonuses triggered by making a deposit at an online casino. With our calculator, you can find out exactly how much you stand to earn – and how much you need to wager on specific games to do so.

For example, say you deposit $100 to claim a 100% casino bonus that holds a 5x bonus wagering requirement. You decide to play that bonus on slots, which hold a 100% game contribution percentage. If we enter those numbers into the bonus calculator, we see that you’ll receive $100 in free bonus money, giving you $200 total. We also see that you’ll need to bet $500 to convert that free bonus money into withdrawable cash.

No Deposit Bonus Calculator

Now, let’s say you find a different online casino that offers a no deposit bonus: a bonus triggered immediately upon registration or opting in. In this example, the no deposit bonus is $10 and holds the same 5x wagering requirement. You decide, again, to play it on slots, which have a 100% game contribution percentage. Enter those numbers into our calculator, and you’ll see that you’d need to bet $50 to convert that bonus into withdrawable cash.

Calculator Fields

Bonus Amount

The bonus amount simply refers to the total amount of bonus funds you’ve claimed.

Percentage Bonus Amount

The percentage bonus amount refers to the percentage match you’re set to receive from a deposit bonus. For example, if you deposit $100 for a 20% match, you’ll receive $20 in free bonus money. If you deposit $100 for a 100% match, you’ll receive $100 in free bonus money.

Wagering Requirements

Wagering requirements, also known as playthrough requirements, dictate how many times you must wager your free bonus money in order to convert it into withdrawable cash. A wagering requirement of 1x is ideal, but many online casinos hold wagering requirements of 5x to 10x, and sometimes even higher. Always read the terms and conditions before attempting to claim a bonus to ensure you’re comfortable with this requirement; otherwise, claiming the bonus at all is not worth it.

Bonus + Deposit

For the wagering requirement, you’ll also have to choose whether that requirement applies to just the bonus money or the bonus money plus the deposit amount. This information can also be found in the terms and conditions. For example, let’s say you make a $100 deposit that grants $100 in free bonus money with a 5x wagering requirement. If the wagering requirement only applies to the free bonus money ($100 x 5), you’d need to wager $500. If it applies to both the free bonus money and the money you deposited ($100 + $100 for a total of $200 x 5), you’d need to wager $1,000.

Game Contribution

All games contribute to wagering requirements differently based on their return-to-player (RTP) percentage. Games that offer better odds generally hold lower game contribution rates, while games that offer lower odds generally hold higher game contribution rates. This rate is displayed as a percentage. As an example, slots may hold a 100% game contribution percentage, while table games may only hold a 25% game contribution percentage. Here’s more on eligible games and contribution rates.

Calculate Button

The final step is to hit ‘Calculate’ and let us do the math for you! Once you do so, you’ll see all of the outputs you need to know depending on the bonus type. If you get an error message, go back and check to make sure you’ve filled in all the fields.



Free Bonus Money

Free bonus money is the total amount of bonus funds you’ll receive.


Total Play Money

Total play money is free bonus money, plus any deposit you made to trigger the bonus.


Amount You Need to Bet

The amount you need to bet is the total wagering required in order to convert your bonus to withdrawable cash.

Why Use a Calculator for a Casino Bonus?

As we mentioned at the top of the page, bonuses can be complicated and confusing, as can their terms and conditions. It’s important to utilize our bonus calculator to learn what you’re getting into before you opt-in or put any of your own money forward. By doing so, you’ll know for sure whether the bonus is worth claiming and whether you’re comfortable with the requirements set forth to convert it to withdrawable cash.

At any time, you can cancel an online casino bonus and forfeit the funds to free yourself of all wagering requirements.
