Why Theoretical EV Beats Basic Wagering Calculators
Most bonus calculators online only tell you your Wagering Target (how much you have to bet). That is not enough context on its own. This tool also estimates Theoretical Expected Value (EV) under explicit assumptions.
The model uses RTP-based house edge, wagering requirements, and payout-rule assumptions around cashout conversion. It is deterministic and useful for comparison, but it does not model variance, completion probability, max cashout restrictions, or operational withdrawal constraints.
Use the EV output as a planning estimate, not a guarantee. Positive theoretical EV does not remove short-term risk.
Cashout Rule Assumptions
Bonus terms can apply different cashout conversion behavior after wagering is completed:
- Full balance cashable — The model treats post-wager balance as cashable.
- Bonus deducted on cashout — The model deducts bonus value before cashout, which can materially reduce expected cashable value.
Casino Bonus Wagering FAQ
What is the difference between "Bonus Only" and "Deposit + Bonus" wagering?
A 30x wagering requirement on "Bonus Only" for a $100 bonus means you must bet $3,000. However, if the casino terms say 30x on "Deposit + Bonus" (assuming a $100 deposit and $100 bonus), you must bet 30x on $200, making your actual wagering target $6,000. Always use our calculator to check the true cost.
Why does the calculator warn me about high RTP games?
Slots with very high RTPs (like Blood Suckers at 98% or 1429 Uncharted Seas at 98.5%) make it mathematically easy to beat wagering requirements. Because of this, almost all online casinos put these specific games on a "restricted list" in their Terms & Conditions. If you play them with bonus money, the casino may confiscate your winnings.
Does a positive EV guarantee I will win cash?
No. EV is a long-term average under model assumptions. Real outcomes depend on volatility, bankroll swings, term enforcement, and game restrictions, so any single result can differ materially from the estimate.
