Set your bankroll, bet size and cashout target. The calculator returns the probability of reaching that multiplier, what the session is worth in expectation, the bankroll it takes to survive the round count, and five simulated sessions drawn from the distribution the game actually uses.

Every number above comes from one relationship. In a crash game with return to player r, the probability that the multiplier reaches m before the round ends is r divided by m.
At 97% RTP a 2.00x target hits 48.5% of the time and a 10x target hits 9.7% of the time. Multiply either probability by its payout and subtract the stake, and the answer is the same: minus three cents on the dollar.
The rest follows from that probability. Survival odds come from modelling the session as a random walk and asking how often the bankroll path touches zero before the final round. The bankroll requirements invert that question at three confidence levels. The outcome range is the middle 90% of the ending-bankroll distribution. The five simulated sessions are drawn from the same distribution, which is the point of showing them: they put a shape on the spread the summary numbers describe.
The one input worth care is RTP. Operators publish it in the game rules panel. Enter what your operator states rather than the default, because the house edge scales directly with it.
Why Predictors and Signal Apps Cannot Work
Most people arriving here searched for something that forecasts the next crash point. It is worth being exact about why nothing does.
Before a round opens, the server generates a seed and publishes its SHA-256 hash. That hash commits the operator to a crash point already fixed and unalterable once betting starts. The multiplier for round 4,001 is therefore not influenced by rounds 1 through 4,000, and it is not observable until the round resolves. There is no signal in the history because the history is not an input.
The crash point derives from a seed held server side. An app running on your phone sees the same public round history you do, and that history contains no information about the next hash. Apps of this kind either return a random number dressed as a forecast, or exist to harvest a deposit through a referral link.
The gambler's fallacy stated in crash terms. Rounds are independent draws. After twenty consecutive crashes below 2x, the probability of the next round reaching 2x is still 48.5%.
Plot enough random data and shapes appear. The distribution here is known and memoryless, so any pattern in a chart of past crash points describes that sample, not the generator. Verifying a completed round against its published hash is the only analysis the data supports.
What is genuinely actionable is narrow but real: pick a cashout target that matches the variance you want, automate it so reaction time stops costing you, size the bankroll for the session length, and set a loss limit before the first round. The calculator quantifies all four.
Aviator Odds at Every Multiplier
Reference values at 97% RTP, calculated with the formula above.
| Target | Win Probability | $10 Payout | EV / $1 |
|---|---|---|---|
| 1.20x | $12.00 | -$0.03 | |
| 1.50x | $15.00 | -$0.03 | |
| 2.00x | $20.00 | -$0.03 | |
| 3.00x | $30.00 | -$0.03 | |
| 5.00x | $50.00 | -$0.03 | |
| 10.0x | $100 | -$0.03 | |
| 20.0x | $200 | -$0.03 | |
| 50.0x | $500 | -$0.03 | |
| 100x | $1,000 | -$0.03 |
Expected loss is always -$0.03 per dollar staked, whichever target you pick. Cashing out at 1.5x and cashing out at 50x carry identical expected value. Only the variance changes.

Casino games carry a mathematical house edge. No strategy, system, or pattern of play can overcome this edge over the long run. If you gamble, do so with money you can afford to lose and set strict session limits before you begin.
