Risk disclaimer
This tool only shows capital requirements and is not investment advice. Martingale is high-risk; losing streaks can cause severe drawdowns or ruin.
What is martingale?
Martingale raises the stake after every loss so one win covers all previous losses: Next Bet = Initial × Multiplier^Losses.
The capital need grows exponentially with a losing streak. This tool quantifies that curve so you can assess risk and account limits.
How to use
- Enter the initial bet (e.g. 100).
- Enter the multiplier after a loss (default 2) and the number of consecutive losses.
- Click Calculate to see the next bet, prior total and total including the next bet.
Formula
- Next Bet = Initial × Multiplier^Losses
- Prior Total = Initial × (Multiplier^Losses − 1) ÷ (Multiplier − 1)
- Total with Next = Prior Total + Next Bet
Example
Initial 100, multiplier 2, 3 losses: next bet 800, prior total 700, total 1,500.
After 10 losses the next bet is 102,400 and cumulative needs exceed 200k — capital demand explodes.
FAQ
Does martingale guarantee recovery?
Only with infinite capital and no limits. In practice account caps, exchange limits and long streaks can wipe you out.
Is a bigger multiplier better?
Bigger multipliers recover faster but explode capital needs faster; 1.5–2 is a common range.
Can these calculations be executed automatically?
Yes. Work out the parameters and risk limits here first, then hand the same rules to a quant system such as CubeQuants so you don't have to place orders manually. Fills still depend on your exchange, so verify with a small size first.
