In Aviator, JetX, Spaceman, and other multiplier-based games, the auto-cashout setting is the single most important variable you control. Should you aim for consistent small wins at 1.10x, or hunt for the massive 10.00x payouts?
This calculator analyzes the expected value (EV), hit frequency, and longest expected losing streak for any cashout target — helping you size your bankroll to survive the variance. Enter your target multiplier and bet size below to see the math.
Why Auto-Cashout Beats Manual Play
Manual cashout relies on split-second reactions under pressure. Auto-cashout removes three failure points:
Network delays can cost you a win. Auto-cashout executes server-side at your exact target.
Watching a multiplier climb past your target triggers greed. Automation eliminates hesitation.
A fixed multiplier target can be analyzed mathematically. “I’ll feel it out” cannot.
Auto-cashout doesn’t improve your odds — the probability formula is the same. But it ensures your actual results match the theoretical model, which is essential for meaningful bankroll management.
How to Use the Optimizer
- Target Cashout (x): Enter your desired multiplier (e.g., 1.50 or 2.00).
- Bet Size ($): Your wager per round.
- House Edge (%): Select based on the platform:
- Aviator (Spribe), JetX, Lucky Jet: 3% house edge (97% RTP)
- BC.Game, Stake, Bustabit: 1% house edge (99% RTP)
- Unknown scripts: Usually 3-4%
- Total Bankroll ($): Your available funds for this session.
- Analyze the Results:
- Hit Probability — how often you’ll win a round
- EV per Bet — the theoretical cost per round
- Streak Analysis — the likely worst losing streak over 1,000 rounds. If your bankroll can’t cover this streak, your target is too aggressive.

EV Comparison: Every Multiplier Loses the Same Amount
This is the most counterintuitive fact about crash games: the expected loss is identical at every cashout target. Here’s the math for a $1 bet:
| Cashout | P(Win) | Profit if Win | EV (97% RTP) | EV (99% RTP) |
|---|---|---|---|---|
| 1.10x | 88.18% | +$0.10 | -$0.030 | -$0.010 |
| 1.50x | 64.67% | +$0.50 | -$0.030 | -$0.010 |
| 2.00x | 48.50% | +$1.00 | -$0.030 | -$0.010 |
| 3.00x | 32.33% | +$2.00 | -$0.030 | -$0.010 |
| 5.00x | 19.40% | +$4.00 | -$0.030 | -$0.010 |
| 10.00x | 9.70% | +$9.00 | -$0.030 | -$0.010 |
The EV column is identical at every row: -$0.030 on Aviator (97% RTP), -$0.010 on BC.Game (99% RTP). This is a mathematical identity — since P(Win) = RTP / Multiplier, the expected loss always equals the house edge percentage of your bet. No cashout target is “better” or “worse” in EV terms.
What differs is variance — and that’s where the real decision lies. For a full analysis including 1,000-round simulations and Martingale breakdown, see our Crash Game Strategy Guide.
Losing Streak Survival: How Much Bankroll Do You Need?
The optimizer’s streak analysis is the most important output. Higher multiplier targets mean longer losing streaks — and your bankroll must survive the worst expected run.
| Cashout Target | Win Rate (97% RTP) | Expected Worst Streak (1K rounds) | Min Bankroll at $1/bet | Variance Profile |
|---|---|---|---|---|
| 1.50x | 64.67% | ~7-10 losses | $50+ | Low — steady grind |
| 2.00x | 48.50% | ~11-15 losses | $75+ | Medium |
| 5.00x | 19.40% | ~25-35 losses | $175+ | High |
| 10.00x | 9.70% | ~50-70 losses | $350+ | Very high |
The rule of thumb: bet no more than 1-2% of your bankroll per round. If you want to target 10x payouts, you need 7x the bankroll of someone targeting 1.50x — not because the EV is different, but because losing streaks are proportionally longer.

The Dual-Bet Approach
Games like Aviator allow placing two simultaneous bets per round. A popular auto-cashout setup is:
Safety net — wins 64.67% of rounds, recovers most of your total bet.
Upside play — wins 19.40%, generates significant profit when it hits.
The math: you win something in 64.67% of rounds (either both bets or just Bet 1), and lose both in 35.33% of rounds. The total EV remains -$0.03 per $1 wagered — but the psychological experience feels smoother because you see partial wins more often than total losses.
