How the math works
At a target multiplier M with RTP R (which you enter), the hit probability is approximately R / M and EV per $1 bet is probability × multiplier ≈ R. The long-run edge is the same at every target — only the variance changes.
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 (enter the game's RTP). EV per $1 bet is probability × multiplier. Expected ruin time uses log(bankroll/stake) / log(1 - loss_per_round).
- Does this work for any crash game?
- Yes — it's generic. Enter the RTP for whatever operator or calibration you're modelling.
- Why are higher cashout targets the same EV as 2x?
- EV is fixed by the game's edge, not the target. For a given RTP R, every target M has EV ≈ R (probability R/M × multiplier M). Same long-run value; wildly different variance.
