How long will my money last?

How long a sum lasts at a given bet, how often it runs out first, and how unusual an evening’s loss was. Every figure is worked out exactly from the published odds of the game and a published pace; nothing you enter leaves this page.

Your game, bet and time

Pick a game, a bet and how long you plan to play. The table shows how long 10 to 100 bets last; enter the money you bring to see your own row.

Red or black at double-zero roulette · $10 a spin (an example bet, not a table minimum) · 2 hours · Las Vegas Strip rating table: 38 spins an hour.

On average, 2 hours of red or black at double-zero roulette at $10 a spin cost $40, about $20 an hour: 76 spins × $10 × 5.26% house edge. A long-run average, not a forecast of one evening.

How long 10, 20, 50 or 100 bets of $10 last over 2 hours. Enter the money you plan to bring to add your own row.

Worked out exactly from the outcome table of the game (see “Show the model”) and the pace: how it’s worked out.

Was that evening unusual?

Enter what an evening cost you; the game, bet and hours are the ones set above. The answer is how often an evening like that loses as much or more.

Enter what you lost to see how often an evening like this loses as much. These 2 hours cost $40 on average.

What exit rules do

Stop when you are down by a set amount, or up by a set amount: here is what that changes, and what it does not.

Exit rules do not change the price of each dollar bet or each hour of play. You lose less on average only because you play less; they do not lower the house edge.

Average result with these rules: −$31, over about 58 of the 76 spins. Without them: −$40 over all 76.

In 4 of 10 evenings (40%) you stop at −$100. In 1 of every 7 evenings (14%) you stop at +$100. In 5 of 10 evenings (45%) you play the full 2 hours and end at about −$9.55 on average.

Doubling after a loss does not change the odds

Betting systems change when you win and lose, not how much the house keeps.

The Martingale doubles the bet after every loss, so that one win recovers the losses plus the first bet.

Every bet in the series carries the same house edge, so the series does too: at double-zero roulette the house keeps 5.26% of every dollar bet, in whatever order the bets come. Frequent small gains are paid for by a rare large loss: the doubling has to stop at the table maximum, and what was lost on the way is not won back.

Example (not a casino’s table): $10 on red at double-zero roulette, $1,000 table maximum. On average a series costs $4.32. About 1 in 89 series (1.1%) meets seven losses in a row: the next bet, $1,280, is over the maximum, and the series has lost $1,270. The other series end $10 ahead.

Worked out from each casino’s own minimum and maximum. The chance per series is the chance of losing every bet of the ladder in a row; at roulette and baccarat every other series ends one minimum bet ahead, and the average cost of a series is what those small gains and the rare big loss add up to: the house edge on every dollar bet in the series.

Roulette: bets on red or black; the zeros lose them. Where the casino does not say which wheel it uses, both wheels are worked out.

Baccarat: the Player bet, 8 decks; a tie leaves the bet in place.

Blackjack: counted in hands, with the source’s figures for its table: 49.09% of hands lost, 42.43% won, 8.48% pushed (a push neither ends nor continues the series). A double, a split or a 3:2 blackjack changes the sums both ways: a finished series can end a little ahead or behind, and the big loss can cost more. The average cost of a series is the house edge of the table’s rules on every dollar bet in it; doubling does not change it.

How it’s worked out

Exact, not a bell curve. For the money you bring and for exit rules, the page follows every possible amount left after every round, using the outcome table of the game. For the chance to be ahead and for the look back, it adds up every possible sequence of rounds. There is no simulation and no normal approximation, which would be badly off for a single-number bet over a short evening.

Assumptions. The same bet every round; rounds are independent; the number of rounds is the pace times the hours, rounded to whole rounds. A round starts only if a full bet is left. At blackjack, a double or split is played in full even when the money left would not cover it, and a result that would go below zero stops at zero.

Where it stops being accurate. Pace depends on the players and the dealer, and electronic tables keep their own pace. The blackjack table is for the source’s rules with basic strategy; your table’s rules and your play change the result. Side bets are not included.

Precision. Chances are rounded to whole percents; below 1% they are shown to one figure or as “1 in N”. Money under $10 is shown in cents, above it in whole dollars.

The average cost per hour is the same figure as in Price of an hour, at the pace set here.

How often runs of one colour happen, and why they do not change the next spin: Streaks.
