How Leverage Works

What leverage actually is

Leverage lets you control a position larger than your cash by borrowing from the exchange. 10x leverage means $1,000 of your money (margin) controls a $10,000 position. Your profit and loss are calculated on the full $10,000 — so a 1% price move becomes a 10% swing on your margin. Leverage doesn't increase your edge; it multiplies whatever happens, good or bad.

Margin, notional & the numbers

*Approximate, after typical 0.5% maintenance margin. The higher the leverage, the closer the exchange's force-close sits to your entry.

Liquidation — the price you must respect

If price moves against you far enough that your margin can no longer cover the loss, the exchange liquidates you: it force-closes the position and you lose your margin. At 100x, a <1% move against you is enough. This is why high leverage isn't "more profit" — it's "less room to be wrong." Always calculate your liquidation price before entering.

Cross vs isolated margin

Isolated: only the margin assigned to that trade is at risk — cleaner, safer, the position dies alone. Cross: your whole balance backs the position, so it's harder to liquidate but a bad trade can take your entire account. Beginners should almost always start isolated.

The hidden cost: funding

Perpetual futures charge funding every 8 hours to keep the perp price near spot. If you're on the crowded side, you pay it; hold a leveraged position for weeks and funding quietly erodes your margin and nudges your liquidation closer. For scalps it's negligible; for long holds it's a real line item.

How much leverage should you use?

Less than you think. The professional approach is to size by risk first (see the risk guide) and let leverage be whatever that math implies — often 2–5x. Leverage is a tool for capital efficiency, not a profit multiplier to max out. The traders who survive treat 100x as a way to get liquidated fast, not a shortcut to riches.

Worked example: a $1,000 long at 10x

Say BTC is at $60,000 and you open a long with $1,000 margin at 10x. Your position size (notional) is $10,000 — worth 0.1667 BTC. With a typical 0.5% maintenance margin, the exchange liquidates you once your loss eats through margin minus that buffer:

Same $950 swing either way — that's what "leverage magnifies both directions equally" means in dollars, not just theory. Drop to 3x on the same $1,000 margin and the position shrinks to $3,000 notional, so BTC has to fall roughly 32% before the same maintenance buffer is breached — far more room for normal volatility. Plug your own entry, size and leverage into the liquidation calculator for the exact number instead of the rough estimate above.

Common leverage mistakes

• Picking leverage before position size. Choosing "20x" first and sizing whatever it allows is backwards — decide the dollar risk you accept, then let leverage fall out of that math.
• Ignoring funding on multi-day holds. A perp held for two weeks against the crowd can lose several percent of margin to funding alone, on top of price risk — see funding rates explained.
• Using cross margin as a default. Cross keeps a losing trade alive longer by drawing on your whole balance — convenient until one bad trade takes the account. Isolated caps the damage to that position.
• Adding margin to a losing position to "buy time." This moves the liquidation price further away but doesn't change that the trade is going wrong — it just makes being wrong more expensive.
• Not checking maintenance margin requirements per coin. Lower-liquidity altcoins often carry higher maintenance margin than BTC/ETH at the same leverage, so the safety table above is a BTC-shaped estimate, not universal.

Frequently Asked Questions

What does 10x leverage mean?

10x leverage means you control a position ten times larger than your margin — $1,000 controls a $10,000 position. Profit and loss are figured on the full $10,000, so a 1% price move produces a 10% change on your margin. It multiplies both gains and losses.

What leverage is safe for beginners?

Low leverage — typically 2x to 5x, or none at all. Lower leverage keeps your liquidation price far from entry, giving normal volatility room to breathe. Beginners should also use isolated margin so a single bad trade can't take the whole account.

How is liquidation price calculated?

Liquidation happens when losses erode your margin below the maintenance requirement. Roughly, a long is liquidated near entry × (1 − 1/leverage + maintenance margin). Higher leverage puts that price closer to entry — at 100x it can be under 1% away. Use a liquidation calculator for the exact figure for your position.

Does leverage increase my profit?

Only relative to your margin, and it increases losses by the same factor. Leverage does not improve your edge or win rate — it magnifies the outcome of each trade. Used carelessly it accelerates account destruction; used with strict position sizing it's just capital efficiency.

What is maintenance margin?

Maintenance margin is the minimum equity the exchange requires you to keep in a position before it force-closes it — typically 0.4%-1% of notional for major pairs like BTC and ETH, higher for illiquid altcoins. It's the buffer in the liquidation math: once your losses eat through your margin down to that threshold, the exchange liquidates rather than risk the position going negative.
