Casinos lure players with huge numbers like “$1000 Bonus!” but hide the truth in the Terms & Conditions. The real value of a bonus depends on the Wagering Requirements (Rollover) and the RTP of the games you play.
This Universal Bonus Calculator reveals the mathematical truth. It calculates the Expected Value (EV) to tell you if a bonus is a profitable opportunity or a mathematical trap.
How to Analyze a Bonus
- Bonus Type:
- Cashable: Once wagering is done, you can withdraw the bonus money. (Most common).
- Non-Sticky (Parachute): You play with cash first. If you win, you can cancel the bonus. If you lose, the bonus saves you.
- Sticky (Phantom): You can never withdraw the bonus amount itself, only the winnings from it.
- Wagering Base: Does the multiplier apply to Bonus Only (Best) or Deposit + Bonus (Worst)? Check the T&Cs carefully!
- Game RTP: Enter the Return to Player of the slot you plan to grind. (e.g., 96% or 98%).
Example: The “D+B” Trap
Offer: 100% up to $100. Wager 35x.
- Scenario A (Wager on Bonus): Total Wager = $100 * 35 = $3,500.
Expected Loss (@ 4% edge) = $140.
Result: -$40 EV (Bad). - Scenario B (Wager on Deposit + Bonus): Total Wager = $200 * 35 = $7,000.
Expected Loss = $280.
Result: -$180 EV (Terrible).
Frequently Asked Questions (FAQ)
What is a “Positive EV” bonus?
A Positive EV bonus is one where the Bonus Amount is larger than the Estimated Loss from wagering. For example, a $100 bonus with a $50 wagering cost has an EV of +$50. These are profitable in the long run.
What is “Playthrough” or “Rollover”?
These are synonyms for “Wagering Requirements.” It is the total amount of bets you must place before the bonus money turns into real cash.
