Rust Crash auto-cashout EV calculator
- Hit probability
- 48.00%
- EV per $1 bet
- $0.960
- Expected rounds to ruin
- 500
How the math works
At a target multiplier M with effective RTP R, the hit probability is approximately R / M. So at 2x with 96% RTP, the hit probability is ~48%. EV per $1 bet is probability × multiplier = 0.96 — meaning you lose about 4 cents on every $1 wagered long-run, regardless of target.
Expected rounds to ruin uses the simple formula bankroll / (stake × loss_per_round). Real-world variance is dramatically higher than this average; use as a planning aid, not a guarantee.

Frequently asked questions
- How does the crash auto-cashout calculator work?
- Win probability is approximately RTP / target multiplier (so at 2x with 96% RTP, ~48%). EV per $1 bet is probability × multiplier. Expected ruin time uses log(bankroll/stake) / log(1 - loss_per_round).
- Is the calculator accurate for Rust Snowball?
- Yes — uses the calibrated RTP band default of 96%. Adjust the RTP input for other operators or other calibration bands.
- Why are higher cashout targets the same EV as 2x?
- EV is fixed by the house edge. 2x at 48% probability = 0.48 × 2 = 0.96 EV. 10x at 9.6% probability = 0.096 × 10 = 0.96 EV. Same long-run; wildly different variance.
