Gambling Bankroll Calculator

“How long will my money last?” Pick a game, your average bet, and how fast you play — this uses the real, validated house edge for that game to estimate your expected loss per hour and roughly how long a bankroll lasts on average.

Read this before you trust the number. This is the long-run AVERAGE only — real-world variance is huge. You could lose your whole bankroll in an hour, or run hot and walk away up. Every casino game is negative expected value; the house wins over time and no system beats it. Treat the figure as “how long this lasts if I get average luck,” not a guarantee. Set a budget you can afford to lose and stick to it. If gambling stops being fun, call or text 1-800-GAMBLER (1-800-426-2537), 24/7.
The math is simple and honest: expected loss/hour = average bet × rounds per hour × house edge. House edges come from our validated odds dataset. Rounds-per-hour defaults are typical published paces — your real pace varies.
