What leverage and margin mean
Leverage is borrowed buying power. It lets you control a position larger than the money you put up yourself. The money you do put up is called margin — a deposit that backs the position.
With 10x leverage, $1,000 of margin controls a $10,000 position. With 5x leverage, the same $1,000 controls $5,000. The leverage number tells you how many times bigger the position is than your margin.
Leverage is often described as a tool for bigger gains, but it works both ways. The same multiplier that turns a 1% gain into a 10% return on margin turns a 1% loss into a 10% loss. That symmetry is the whole point of understanding the maths before using it.
Margin is not a fee and not the cost of the trade. It is your own money held aside while the position is open, and it is returned when the position closes — minus any losses the position made.
- Leverage is borrowed buying power; margin is your own deposit.
- 10x leverage: $1,000 of margin controls a $10,000 position.
- Leverage multiplies gains and losses equally.
The margin formula
Required margin is the notional value of the position divided by the leverage. First work out the notional value — price × quantity — then divide by the leverage you plan to use.
A worked example: buying 1 coin at $60,000 gives a notional value of $60,000. At 10x leverage, the required margin is $60,000 ÷ 10 = $6,000. At 5x leverage it would be $12,000, and at 20x it would be $3,000.
Higher leverage means less margin for the same position, which leaves more of your balance free — but it also means a smaller price move wipes out the margin. At 20x leverage, a 5% move against you consumes the entire margin.
Some platforms add extra margin requirements or charge fees on the leveraged amount, so the margin shown by a calculator is the basic requirement. Check your platform's own rules before opening a position.
- Required margin = notional value ÷ leverage.
- Example: $60,000 notional at 10x leverage needs $6,000 margin.
- Higher leverage needs less margin but tolerates smaller moves.
Notional value: the number that decides your risk
Notional value is the full value of the position, and it is the number that decides your risk. A 1% move on a $60,000 notional position is $600 — whether you used $6,000 of margin at 10x leverage or the full $60,000 with no leverage at all.
This is the part that catches beginners out. The margin looks small, so the trade feels small, but the profit and loss behave like a $60,000 trade. The leverage only changes how the result compares with the money you put up.
Before opening a leveraged trade, always ask: how much would I lose if the price moved 1% against me? The answer is 1% of the notional value. If that number is uncomfortable, the position is too big or the leverage is too high.
A leverage and margin calculator shows you the notional value alongside the margin, so you can see both numbers before committing. The notional value is the one to plan your risk around.
Liquidation prices are approximate
Liquidation is the point where the platform closes your position because the margin can no longer cover the losses. A calculator can estimate that price from your entry, leverage and margin mode, but the figure is approximate, not exact.
The real liquidation price depends on the platform's maintenance margin — the minimum margin you must keep while the position is open — plus trading fees and any funding costs that build up while the position is held. These vary by platform and by market, so two platforms can liquidate the same position at different prices.
Margin mode also matters. With isolated margin, only the margin assigned to the position is at risk, so liquidation ends that position and nothing else. With cross margin, the whole account balance backs the position, which can delay liquidation but also means a bad trade can draw on more of your money.
Treat any liquidation figure as a guide and keep a safety margin from it. If your plan depends on the price never reaching the estimated liquidation level, the position is too large or the leverage too high.
- Liquidation prices from a calculator are approximate, not exact.
- Maintenance margin, fees and funding costs all shift the real level.
- Isolated margin risks only the assigned margin; cross margin risks the whole balance.
The bottom line
Leverage magnifies losses exactly as much as it magnifies gains. A small move against a highly leveraged position can wipe out the margin entirely, and it can happen faster than you expect.
A calculator shows you the maths — the notional value, the required margin and the approximate liquidation price — but it cannot tell you which leverage level is safe. There is no safe leverage level in general; safety depends on the position size, the market and how much you can afford to lose.
If you use leverage, keep the position small, know the notional value, and know where the approximate liquidation price sits. Never risk money you cannot afford to lose.
