How Leverage Works

How Leverage Works

Leverage is the defining feature of perpetual futures. It lets you control a large position with a small amount of capital. It's also the reason most new traders blow up their accounts. Let's make sure you understand it completely.

The Core Mechanic

Leverage is a multiplier on your capital. When you deposit margin (your collateral), leverage determines how much total exposure you get:

Position Size = Margin x Leverage

So with $1,000 margin and 10x leverage, you control a $10,000 position. You only put up 10% of the total value — the exchange effectively "lends" you the rest.

The margin requirement is the inverse of leverage:

| Leverage | Margin Required | You Deposit | You Control |

|----------|----------------|-------------|-------------|

| 2x | 50% | $1,000 | $2,000 |

| 5x | 20% | $1,000 | $5,000 |

| 10x | 10% | $1,000 | $10,000 |

| 20x | 5% | $1,000 | $20,000 |

| 50x | 2% | $1,000 | $50,000 |

Amplified Gains AND Losses

Here's the part many beginners overlook: leverage multiplies movement in both directions. Let's trace through a real example.

Setup: You have $1,000 and go long on ETH at $3,000.

Scenario: ETH rises 10% to $3,300

| Leverage | Position Size | Profit | Return on Margin |

|----------|--------------|--------|------------------|

| 1x (spot) | $1,000 | $100 | +10% |

| 5x | $5,000 | $500 | +50% |

| 10x | $10,000 | $1,000 | +100% |

| 20x | $20,000 | $2,000 | +200% |

Looks incredible, right? Now flip it.

Scenario: ETH drops 10% to $2,700

| Leverage | Position Size | Loss | Return on Margin |

|----------|--------------|------|------------------|

| 1x (spot) | $1,000 | -$100 | -10% |

| 5x | $5,000 | -$500 | -50% |

| 10x | $10,000 | -$1,000 | -100% (liquidated) |

| 20x | $20,000 | -$2,000 | -200% (liquidated earlier) |

At 10x leverage, a mere 10% price drop wipes out your entire margin. At 20x, you'd be liquidated after just a 5% drop.

Liquidation: The Line in the Sand

When your losses approach your margin, the exchange liquidates your position — forcibly closes it to prevent negative balance. Your liquidation price depends directly on your leverage:

Approximate liquidation distance = 1 / Leverage

• 2x leverage — liquidated at ~50% adverse move
• 5x leverage — liquidated at ~20% adverse move
• 10x leverage — liquidated at ~10% adverse move
• 20x leverage — liquidated at ~5% adverse move
• 50x leverage — liquidated at ~2% adverse move

These are approximations assuming a 0.5% maintenance margin rate. Actual liquidation distances vary by exchange.

With 50x leverage, a normal 2% candle can wipe you out. Bitcoin regularly moves 2-5% in a single hour.

A Practical Example: The Smart Way

Let's compare two traders with the same $1,000 account, both going long on BTC at $60,000:

Trader A — Uses 3x leverage:

• Position size: $3,000 (0.05 BTC)
• Liquidation price: ~$40,000 (BTC needs to drop 33%)
• Can survive a major crash and wait for recovery

Trader B — Uses 25x leverage:

• Position size: $25,000 (0.417 BTC)
• Liquidation price: ~$57,600 (BTC needs to drop only 4%)
• Gets liquidated by normal market noise

Trader B has a bigger position but will almost certainly get liquidated before any meaningful trend plays out. Trader A has room to breathe.

The Golden Rules of Leverage

1. Start with 2x-5x leverage. Seriously. Even professional traders rarely exceed 10x.
2. Higher leverage = closer liquidation. You're not "making more money" — you're accepting more risk of total loss.
3. The market doesn't care about your leverage. A 5% drop is a 5% drop. Leverage just determines whether that 5% drop ruins your day or ends your account.
4. Size your position, not your leverage. Decide how much risk (in dollars) you can afford to lose, then work backward to determine appropriate leverage.

Pro tip: Many successful traders use the minimum leverage necessary to achieve their desired position size. If you want $5,000 exposure and have $2,500, use 2x — not 50x with $100.
