Martingale Calculator

What is martingale in trading?

In a martingale plan you start with a small amount. If the trade loses, the next trade is bigger, for example 2 or 2.25 times the last one. You keep increasing after every loss until a trade wins. The idea is that the winning trade pays back all earlier losses plus a small profit.

The problem is that the amounts grow very fast. After a few losses the next trade can be bigger than your whole account. When that happens, the plan fails and the loss is huge compared with the small profit you were trying to make.

How to use the martingale calculator

1. Enter your account balance.
2. Enter the first stake, the amount of your first trade.
3. Enter the payout % of your platform.
4. Enter the multiplier, or press the button to use the break-even multiplier for your payout.
5. Choose how many losses in a row to show (up to 12).
6. Read the table: stake, total risked and the result if that trade wins. Red rows are trades your balance cannot pay for.

Worked example with numbers

Balance 1,000, first stake 10, payout 80%. To recover all losses at 80% payout, the multiplier must be at least (1 + 0.8) ÷ 0.8 = 2.25.

With 2.25×, every win at any step leaves you exactly +8 ahead. But look at the risk: after 5 losses you have risked 453.32 in total, and the 6th trade needs 576.65, which brings the total to 1,029.97. That is more than your balance. So you are risking about 1,030 to make 8.

Why "just double it" does not work in binary options

In casino examples, martingale doubles the bet because a win pays 100%. In binary options the payout is less than 100%, so doubling is not enough. With an 80% payout and a 2× multiplier, the stakes are 10, 20, 40, 80. If the 4th trade wins, you get 80 × 0.8 = 64, but you already lost 70. You end at −6 even after "winning".

So martingale in binary needs an even bigger multiplier, which makes the balance run out even faster.

Why martingale blows accounts

• Losing streaks are normal. With a 55% win rate, the chance of 6 losses in a row is about 0.8% each time — so over a few hundred trades it is likely to happen at least once.
• The stake grows like 1, 2.25, 5, 11, 26, 58… so the damage of one bad streak is enormous.
• The profit per cycle stays tiny (one base win), while the loss when the plan fails is almost the whole account.
• Platforms have maximum trade sizes, so you may not even be allowed to place the next step.
• It pushes you to trade faster and emotionally after losses, which lowers your win rate.

A safer alternative: fixed risk per trade

Instead of increasing after losses, keep every trade at 1–2% of your balance and stop at a daily loss limit. A losing streak then costs a few percent, not your account. If you want growth, let the trade size follow your balance (compounding), so it gets smaller after losses and bigger after wins. The compounding calculator and money management plan show how.
