Understanding Casino Bonus EV

What is Bonus EV?

Most casino bonuses look attractive on paper, but wagering requirements often make them unprofitable. Bonus EV calculates your real expected profit after accounting for the house edge on required wagering.

The Formula

EV = Bonus Amount - (Total Wagering Required × House Edge)

Where: Total Wagering = (Bonus + Deposit or Bonus Only) × Wagering Requirement

Key Factors

  • Wagering Requirement: Lower is better (20x good, 50x+ bad)
  • House Edge: Play low edge games when allowed
  • Bonus vs Bonus+Deposit: Bonus-only wagering is more favorable
  • Max Cashout: Limits your potential profit
  • Game Restrictions: Often forced to play high-edge slots

Typical Bonus Scenarios

✓ Positive EV Bonus

$100 bonus, 20x wagering on bonus only, 1% edge = +$80 EV

≈ Break-Even Bonus

$100 bonus, 35x wagering on bonus+deposit, 2% edge = ~$0 EV

✗ Negative EV Bonus

$50 bonus, 50x wagering on bonus+deposit, 5% edge = -$125 EV

Smart Bonus Strategy

  • Calculate EV before accepting any bonus
  • Look for low wagering requirements (under 30x)
  • Choose bonuses that allow low house edge games
  • Be aware of max cashout limits
  • Read all terms and conditions carefully
  • Sometimes it's better to play without a bonus
