Martingale Calculator: Ladder and Break Risk
Type a first bet, how much you raise it after a loss and the money you have set aside. The calculator lays out the bet ladder, shows how many losses in a row you can cover, how often the plan breaks and what one cycle costs on average.
What the plan is
A Martingale plan raises the bet after every loss so that one win pays back everything lost so far. You start with a first bet. After a loss, the next bet is the last one times a fixed number, usually 2. After a win, you go back to the first bet. One run from a first bet to the first win is a cycle.
The idea sounds sensible because a cycle that ends in a win nets the first bet, whatever came before it. The trouble is the other kind of cycle. The plan breaks when the next bet is more than the money you set aside, or more than the biggest bet the game allows. Then every bet in the ladder is lost.
How to use the calculator
Type the first bet, the number you multiply by after a loss, the chance a round is won, what a win returns (2 means even money), the money set aside and the rounds you expect to play. Under “More settings” you can add a fee and a biggest-bet limit.
The tiles show how many losses in a row your money covers, what a break costs, the exact average result of a cycle, how likely a break is in your rounds and how long a plan typically lasts. Below them are the bet ladder and two tables, and pretend sessions at the bottom let you watch the plan run.
A worked example
The starting figures are an illustration, not any platform’s rules: a ₹100 first bet, doubling after a loss, a 49% chance of winning a round, a 2× payout and ₹10,000 set aside. The ladder is:
| Bet | Amount | Total staked | A win on this bet nets |
|---|---|---|---|
| 1 | ₹100 | ₹100 | ₹100 |
| 2 | ₹200 | ₹300 | ₹100 |
| 3 | ₹400 | ₹700 | ₹100 |
| 4 | ₹800 | ₹1,500 | ₹100 |
| 5 | ₹1,600 | ₹3,100 | ₹100 |
| 6 | ₹3,200 | ₹6,300 | ₹100 |
A seventh bet would be ₹6,400 and bring the total to ₹12,700, which is more than ₹10,000. So the money covers 6 losses in a row. A cycle breaks when its first six bets all lose, and that happens in 1.76% of cycles. It looks rare, but you keep playing. Over 100 rounds the chance of at least one break is 58.4%, and half of all plans have broken by round 80.
The average says the same thing. A cycle gains ₹100 in 98.24% of cases and loses ₹6,300 in 1.76%. Added up exactly, that is −₹12.62 per cycle. The game keeps 2.00% of every rupee staked, and the plan stakes ₹630.81 per cycle on average. 2.00% of ₹630.81 is the same ₹12.62.
More money does not fix it
Set aside ₹1,00,000 instead and the ladder reaches 9 losses. The ninth bet is ₹25,600 and the total is ₹51,100. Here is the same plan with different amounts set aside, over 100 rounds:
| Losses covered | Money needed | Chance of a break | Average result |
|---|---|---|---|
| 5 | ₹3,100 | 83.7% | −₹254.22 |
| 6 | ₹6,300 | 58.4% | −₹425.28 |
| 7 | ₹12,700 | 35.1% | −₹595.21 |
| 8 | ₹25,500 | 19.3% | −₹748.51 |
| 9 | ₹51,100 | 10.2% | −₹885.59 |
Breaks get rarer, and the average result gets worse. A bigger ladder puts more money through a game that keeps 2.00% of it. Over these 100 rounds the 6-loss plan stakes ₹21,264 on average, against ₹10,000 for flat ₹100 bets, which would lose ₹200. A bigger pile buys fewer breaks and costs more.
Why no ladder beats the average
Every bet has the same average result: minus the game’s edge times the bet. A plan only decides how much is bet and when. Betting more after a loss sends more money through the edge, so the average result of a cycle is always minus the edge times the money staked per cycle. If the game keeps nothing (a 50% chance at 2×), the average is exactly zero and the plan merely trades many small gains for a rare large loss.
Real games can be harsher than the example. A fee can turn a deep win into a net loss, and a smaller multiplier gives a longer ladder whose wins stop paying back the losses. The calculator marks the bet where that starts.
What it cannot tell you
It does not know any game’s real rules. The chance, payout and fee are the ones you type, and the presets are illustrations: use the figures your own app states. It treats every round as independent, so it predicts nothing about the next one. It also leaves out what an app may add, such as minimum bets, rounding or bonuses. Pretend sessions use your browser’s random numbers, not any app’s game.

Common questions
What does it mean when the calculator says a plan breaks?
The plan breaks when the next bet in the ladder is more than the money you set aside, or more than the biggest bet the game allows. The cycle then ends with every bet in it lost. With a ₹100 first bet, doubling and ₹10,000 set aside, six losses in a row break it.
How much money do I need to cover ten losses in a row?
With a ₹100 first bet and doubling, ten losses in a row stake ₹1,02,300 in total, and twelve stake ₹4,09,500. Each extra loss you want to cover about doubles the money, because every bet is twice the one before it.
Does raising the bet by less than double help?
It lengthens the ladder: raising by 1.5× instead of 2× lets ₹10,000 cover 9 losses instead of 6. But a win then stops paying back what was lost. At a 2× payout, a win on the third bet of the 1.5× ladder returns ₹450 against ₹475 staked.
What does a fee do to a doubling plan?
A fee taken from each stake lowers what a win returns. With a 2% fee on a 2× payout a win returns 1.96 times the bet, so a win on the sixth bet gives back ₹6,272 against ₹6,300 staked. The fee also lifts the game’s edge to 3.96%.
Can the calculator tell me when a losing run will end?
No. Each round is a fresh random draw, so a run of losses does not make a win any more likely. The calculator counts how often runs of a given length turn up over many rounds. It cannot say when the next one comes.
Are my bet sizes and money stored or sent anywhere?
No. Everything is worked out in your browser and nothing is saved. If you press the copy-link button, the numbers go into the link after the # sign, and a website never receives that part.
