How Does the Wagering Calculator Work?

Our wagering requirements calculator uses several different inputs to estimate your wagering requirements and potential outcomes. To get started, simply fill in the fields. If you select one of our partnered casino offers, many of these fields will be filled automatically.

Understanding the Outcome

Based on your inputs, the calculator provides you with three key outputs:

  1. Total Play Money: This is the sum of your initial deposit and the bonus you receive. It’s your starting bankroll.
  2. Amount to Wager: This is the total amount of money you must bet to successfully meet the wagering requirements and unlock your winnings for withdrawal.
  3. Theoretical Outcome: This is an estimate of your balance after completing the wagering, based on the game’s RTP. A positive number suggests a theoretical win, while a negative number suggests a theoretical loss. Please note: This is based on statistical averages and your actual experience will vary due to luck and variance.

Gambling addiction warning

Gambling is a fun activity that isn't intended to be used for financial gain.
