Casino Bonus Calculator to Work Out Wagering Requirements

Use this casino bonus calculator to estimate how much you need to wager before you can withdraw. It turns wagering requirements into a clear number based on your inputs.

This wagering requirement calculator is designed for a simple question: how much do I need to wager before I can withdraw? Wagering requirements are the number of times you must play through a bonus before any winnings can be withdrawn.

The math behind this is simple. You take the total amount the requirement applies to, then multiply it by the wagering figure. If a bonus has a 30x requirement, you need to play through that total amount thirty times before meeting the condition. The calculator does this for you, so you can focus on the outcome rather than the calculation. For a full breakdown of how bonuses work, you can refer to the bonus guide.

The tool also uses a 96 percent RTP assumption to estimate what happens during that wagering. This reflects a typical return level for many slot games and allows the calculator to estimate expected loss while you complete the requirement. It does not predict results for any single session, but it provides a consistent baseline for comparison. In effect, this works as a bonus expected value calculator using your figures.

In practice, this means the output is often negative. If the wagering requirement is high, the expected loss during play can outweigh the value of the bonus. This is the key point the calculator highlights when answering “is this bonus worth it.”

This process can be easier to interpret with a simple visual.

As a general rule, wagering requirements under 25x are easier to clear, while 40x or higher can be difficult to complete without significant loss.
