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.
- Choose a Casino Offer: Select from a list of pre-vetted casino bonuses. This will automatically populate the bonus details, or you can select “Custom” to enter the details manually.
- Deposit Amount: Enter the amount of money you plan to deposit into your casino account (e.g., $100).
- Wagering Requirement (x): It automatically uses the wagering multiplier you need to meet (e.g., 35x) for each casino. This is the number of times you must bet your bonus, or bonus + deposit, before you can withdraw winnings.
Understanding the Outcome
Based on your inputs, the calculator provides you with three key outputs:
- Total Play Money: This is the sum of your initial deposit and the bonus you receive. It’s your starting bankroll.
- 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.
- 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.
