Martingale Calculator: When Doubling Breaks

Updated 8 October 2026 · 5 minute read

“Double after a loss” is passed round in groups as a way to get everything back. Type a first bet, your money and the odds, and see the ladder, how often it breaks and the exact average cost. It opens on ₹100 and ₹10,000.

These starting figures are an illustration, not any platform’s rules. Replace them with the odds, payout and fee your own game states. A payout of 2 means even money (a win returns twice the stake). Bets are shown unrounded; if your app takes whole rupees only, round each bet up, which makes the totals slightly bigger.

6losses in a row ₹10,000 covers
₹6,300lost if the plan breaks
₹96gained when the first bet wins

80rounds until the first break: half of plans break sooner
−₹842.05average result over 100 rounds (exact)
1.76%chance one cycle ends in a break

With a ₹100 first bet and doubling the bet after every loss, ₹10,000 covers 6 losses in a row. The next bet, ₹6,400, would be more than the ₹3,700 left. From bet 6 on, a win no longer gets back everything staked so far. At a 49% win chance and a 2× payout with a 2% fee the game keeps 3.96% of every rupee staked, so a cycle breaks 1.76% of the time and the exact average result of a cycle is −₹24.98.

Try the plan with pretend money

Pretend sessions play the plan round by round with random numbers from your browser and the figures above. There is no money in it, and it is not any app’s game. Each press gives different results; the exact figures above never change.

The plan has a name, martingale: raise the bet after each loss, usually by doubling it, so that the first win pays back everything lost since the plan began plus one first bet. The box above opens on invented numbers: a ₹100 first bet, ₹10,000 set aside, a bet that is won 49 rounds in 100 and pays 2×, and 2% of every stake kept as a fee. At the time of writing (8 October 2026) we could not read Shree Win’s rules, so none of these are its figures.

The ladder, rung by rung

BetAmountA win on it nets
1₹100+₹96
2₹200+₹92
3₹400+₹84
4₹800+₹68
5₹1,600+₹36
6₹3,200−₹28

The six bets add up to ₹6,300, and the seventh, ₹6,400, is more than the ₹3,700 left. So six losses in a row break this plan. The fee explains the odd rows: a ₹3,200 win returns ₹6,272, which is less than the ₹6,300 staked, so the sixth rung loses even when it wins. A cycle breaks 1.76% of the time.

Reading the result boxes

Under the inputs, eight boxes answer in order: how many losses in a row your money covers (6), what a break costs (₹6,300), what the first bet wins (₹96), the exact average of one cycle (−₹24.98), the chance of a break within your rounds (58.4%), the round by which half of plans have broken (80), the exact average over those rounds (−₹842.05) and the chance that one cycle breaks (1.76%). “Exact” means counted, not guessed. The pretend-sessions button plays the plan with your browser’s random numbers and no money, so you can watch a break arrive.

Same money, different first bets

Every row sets aside ₹10,000 and plays 100 rounds.

First betLosses coveredLost if it breaksGained on a first-bet winChance of a breakAverage result
₹109₹5,110₹9.6010.2%−₹175
₹208₹5,100₹19.2019.3%−₹296
₹507₹6,350₹4835.1%−₹589
₹1006₹6,300₹9658.4%−₹842
₹2505₹7,750₹24083.7%−₹1,258
₹5004₹7,500₹48097.9%−₹1,182

A smaller start buys more rungs and fewer breaks, and it wins less when it works. No row has a positive average. The last row costs less on average than the one above it only because the tool stops the plan at its first break, which comes sooner.

How a break builds up

On the ₹100 start, the chance of at least one break grows with the length of the session:

RoundsChance of a breakAverage result
105.2%−₹104
2013.5%−₹219
5034.3%−₹507
10058.4%−₹842
20083.3%−₹1,188
50098.9%−₹1,405

Flat ₹100 bets over the same 100 rounds stake ₹10,000 and average −₹396. The doubling plan stakes about ₹21,264 and averages −₹842. It does not change what a rupee costs. It makes you stake more rupees.

If a limit applies

Platforms of this kind often cap one stake. With an ₹800 cap the same ladder stops after four bets, a break costs only ₹1,500, and the average result over 100 rounds is −₹236.50. But breaks come at 6.77% of cycles, and at least one turns up in 97.9% of 100-round sessions, with half arriving within 20 rounds.

What it cannot tell you

The calculator does arithmetic on the numbers you type. It does not know what any Shree Win tile pays, and the odds are yours to supply. If a chat group is selling the plan as a method, read the hack guide and the streak calculator, which shows how often the long losing runs behind a break turn up. If you are already down money and thinking of doubling to get it back, the loss recovery calculator puts that wish into numbers first. The Win Go guide describes the round, and the tools page lists the rest.

Common questions

Most cycles win, so why is the average result below zero?

Because the rare loss is huge. In the opening example 96.55% of cycles end in a gain of ₹36 to ₹96, 1.69% end in a win that still loses ₹28, and 1.76% break and lose ₹6,300. Weighed by how often each happens, the exact average result of a cycle is −₹24.98. A frequent small gain and a rare large loss can still add up to a cost.

How much money does a ₹10 first bet need to double ten times?

₹10,230, because the ten bets are ₹10, ₹20, ₹40 and so on up to ₹5,120. With ₹10,000 set aside you can fund only 9, so a tenth loss in a row breaks the plan. Each extra step on the ladder costs as much as everything before it, plus one more first bet.

What do I type in the biggest bet box if I cannot find a limit?

Leave it at 0, which means none. We could not read any table or bet limit for Shree Win, so any limit here is yours to type from your own bet screen. If your screen caps a stake at ₹800, type 800 and watch the ladder shorten.

Would tripling after a loss get me out faster than doubling?

It reaches the break sooner. With the opening numbers and tripling, ₹10,000 covers only 4 losses in a row, a break costs ₹4,000, and the chance of at least one break in 100 rounds is 97.9% against 58.4% for doubling. The average result over those 100 rounds is −₹484.81, and a win on the first bet still nets only ₹96.

Does it matter whether I start at ₹10 or ₹100 if I double either way?

Yes, a great deal. With the same ₹10,000, a ₹10 start covers 9 losses and breaks in 10.2% of 100-round sessions, while a ₹100 start covers 6 and breaks in 58.4%. The small start also wins only ₹9.60 at a time. The table in this page sets out six first bets side by side.

A group says it only plays until one win. Does that change the arithmetic?

Not the cost of a cycle, only how many cycles you play. Stopping after the first one means a 96.55% chance of a gain of ₹36 to ₹96, and a 1.76% chance of losing ₹6,300. Each further cycle runs the same draw again, so the chance of at least one break builds up cycle by cycle.
