Martingale Calculator for Roulette
Enter your base bet, bankroll and table limit. The calculator shows every step of the Martingale, how long a losing run you can cover, and how a whole session plays out on a European, French or American wheel.
How the Martingale works in roulette
You bet on an even-money outcome such as red and double the stake after every loss. The first win recovers everything lost in the run and adds one base bet, then you go back to the start. The table below is the classic 1-unit sequence on a European wheel.
| Step | Bet | Total staked | Profit if it wins | Chance of reaching this step |
|---|---|---|---|---|
| 1 | 1 | 1 | +1 | 100.00% |
| 2 | 2 | 3 | +1 | 51.35% |
| 3 | 4 | 7 | +1 | 26.37% |
| 4 | 8 | 15 | +1 | 13.54% |
| 5 | 16 | 31 | +1 | 6.95% |
| 6 | 32 | 63 | +1 | 3.57% |
| 7 | 64 | 127 | +1 | 1.83% |
| 8 | 128 | 255 | +1 | 0.94% |
| 9 | 256 | 511 | +1 | 0.48% |
| 10 | 512 | 1023 | +1 | 0.25% |
Two limits end a run early: your bankroll and the table maximum. A bankroll of 127 units covers seven steps, 1,023 units covers ten. A table limit of 100 with a 1-unit base stops at the seventh step (64), however deep your pockets are.

How the session results are calculated
The calculator follows every possible balance and step spin by spin, so the numbers are exact rather than a random simulation. A session stops early when the next bet is larger than your balance or the table limit. Compare this with Fibonacci, D’Alembert, Labouchère and Paroli on live tables, or try the sequence yourself in the free roulette simulator.

FAQ
- How much money do you need for the Martingale?
- To cover n losses in a row with a base bet b you need b × (2ⁿ − 1): 127 units for seven steps, 255 for eight, 1,023 for ten.
- How often does a run of losses happen?
- On a European wheel a single even-money bet loses 51.35% of the time, so seven losses in a row start about once in every 107 cycles. Over hundreds of spins long runs are normal, as the live table above shows.
- Does the table limit matter?
- Yes. Doubling reaches the table maximum quickly, and after that the sequence can no longer recover the run. Set your table limit in the calculator to see where it stops.
