Aviator Bankroll & EV Calculator
Unlike "strategy" tools that promise an edge, this calculator shows you the cold mathematical reality of the Aviator game. Every number below is derived from the Provably Fair probability distribution. The house edge is 3% regardless of your strategy — this tool helps you understand how long your bankroll will last and what to expect.

How Is This Calculated?
Every number in this calculator is derived from one formula: P(reaching multiplier m) = 0.97 / m. This is the exact probability distribution built into Aviator's Provably Fair algorithm with a 3% house edge. For any target multiplier:
- Win probability = 0.97 / m (e.g., at 2.0x: 0.97/2.0 = 48.5%)
- Profit per win = bet × (m − 1) (e.g., $1 bet at 2.0x: $1.00 profit)
- Expected value per bet = P(win) × profit − P(loss) × bet = always −3% of bet
- Expected rounds = bankroll / (bet × 0.03) — simplified estimate based on average loss rate
The Monte Carlo simulation runs 1,000 independent sessions of 100 rounds each with your parameters, using cryptographically-random crash points following the P(m) = 0.97/m distribution. This gives realistic variance estimates beyond simple EV calculations.
