How it works
Leverage lets you control a position larger than your cash. The margin blocked is the position value divided by the leverage. Because the whole position moves, a small adverse move is a large percentage of your own money, the calculator shows exactly how large.
The formula
Position = Cash × Leverage · Margin = Position ÷ Leverage · Loss = Position × Stop-loss %- Cash
- Money available in your account
- Leverage
- Multiple offered by the broker
- Stop-loss %
- Adverse move at which you exit
Worked example
₹1,00,000 at 5× controls ₹5,00,000; a 2% adverse move costs ₹10,000, which is 10% of your cash.
