Bankroll Calculator
Betting big is a bankroll problem before it's a luck problem. Enter your numbers below to estimate how long a bankroll lasts at a given stake — and the risk that comes with it. It's an estimate, not a promise: the house edge means the longer you play, the more likely the math catches up.

Estimates only. "Expected hands" assumes flat betting and the long-run house edge; real sessions swing far above and below it. This tool does not change the odds and is not advice — it's for planning a bankroll. 21+. Play responsibly.
What the numbers mean
Raw hands is simply bankroll ÷ average bet — how many bets you could place if you broke even every time. Expected hands divides your bankroll by the expected loss per bet (average bet × house edge), estimating how long the bankroll lasts on average once the edge is applied. Real variance means you'll often last much longer or bust much sooner.
The lesson high rollers already know: the bigger your bet relative to the bankroll, the faster variance can end the session. Size stakes to the bankroll — see high-roller bankroll strategy.
What number to enter
The single input that changes the result most is the house edge, and it varies widely by game. As a rough guide for the edge field above: blackjack on basic strategy runs around 0.5%, baccarat about 1.06% on banker, single-zero roulette about 2.7% and double-zero roulette about 5.26%, while slots typically sit anywhere from 2% to 10% depending on the title's published RTP. A high-limit table with a low edge stretches a bankroll far longer than a high-variance slot at the same stake — which is why game choice matters as much as bet size. Pair this with the bankroll strategy guide for how to size the stake itself, and read highest-limit table games for where the low-edge, high-cap tables are.
Common questions
How long will my bankroll last at high stakes?
On average, roughly your bankroll divided by (average bet × house edge) — that's the “expected hands” figure above. It's a long-run average, not a promise: real sessions swing far above and below it because of variance.
What house edge should I enter?
Use the figure for the game you play: about 0.5% for blackjack on basic strategy, ~1.06% for baccarat, ~2.7% (single-zero) or ~5.26% (double-zero) for roulette, and 2–10% for slots depending on the published RTP.
Does a bigger bankroll improve my odds?
No. A bigger bankroll doesn't change the house edge — it only lets you play longer and absorb larger swings before the math catches up. The odds on each bet stay the same.
How many rounds per hour is realistic?
Slots can exceed 400–600 spins per hour; live-dealer blackjack runs roughly 60–80 hands; baccarat and roulette are slower. Faster play means more total wagered, so more exposure to the edge.
Is the estimate a guarantee?
No. It's a planning tool based on the long-run edge and flat betting. Variance means you'll often last much longer or bust much sooner; never stake money you can't afford to lose. Play responsibly.
