In futures trading, margin is a core concept you must understand. Margin is essentially the "deposit" you put up when opening a position. Understanding how margin works is key to managing your positions and risk effectively. Sign up on Binance to view real-time margin information on the futures trading interface.
What Is Margin?
Initial Margin
The minimum funds required to open a position — your "entry ticket." The amount depends on your position value and leverage level.
Formula: Initial Margin = Position Value / Leverage
Example: You want to open a 10,000 USDT BTC long position with 10x leverage.
Initial Margin = 10,000 / 10 = 1,000 USDT
This means you only need 1,000 USDT to control a 10,000 USDT position.
Maintenance Margin
The minimum margin required to keep a position open. When your margin drops to the maintenance level due to unrealized losses, forced liquidation is triggered.
Maintenance margin rates vary by position size:
| Tier | Position Value Range | Maintenance Margin Rate |
|---|---|---|
| Tier 1 | 0-50,000 USDT | 0.40% |
| Tier 2 | 50,000-250,000 USDT | 0.50% |
| Tier 3 | 250,000-1,000,000 USDT | 1.00% |
| Higher | Larger positions | Higher rates |
Note: Maintenance margin rates differ by trading pair — check the Binance App for exact figures.
Margin Calculation Examples
Example 1: 10x Leverage Long BTC
- BTC price: 65,000 USDT
- Quantity: 0.1 BTC
- Position value: 65,000 x 0.1 = 6,500 USDT
- Leverage: 10x
- Initial margin: 6,500 / 10 = 650 USDT
You only need 650 USDT to hold a 6,500 USDT BTC long position.
Example 2: 5x Leverage Short ETH
- ETH price: 3,500 USDT
- Short quantity: 2 ETH
- Position value: 3,500 x 2 = 7,000 USDT
- Leverage: 5x
- Initial margin: 7,000 / 5 = 1,400 USDT
Example 3: Calculating Liquidation Price (Long)
Using Example 1:
- Initial margin: 650 USDT
- Maintenance margin rate: 0.4%
- Maintenance margin: 6,500 x 0.4% = 26 USDT
- Maximum bearable loss: 650 - 26 = 624 USDT
- Maximum drop before liquidation: 624 / 6,500 = ~9.6%
- Liquidation price: 65,000 x (1 - 9.6%) = ~58,760 USDT
This means if BTC drops from 65,000 to approximately 58,760, your position will be force-liquidated.

Cross vs. Isolated Margin
Isolated Margin Mode
Each position has its own dedicated margin. The maximum loss for any position is limited to its allocated margin.
Pros: Controllable risk — one position's liquidation doesn't affect others.
Cons: You need to manually add margin if it runs low, making positions more prone to liquidation.
Cross Margin Mode
Your entire futures account balance serves as shared margin for all positions.
Pros: Less likely to be liquidated (larger margin pool), suitable for hedging strategies.
Cons: A single liquidation can wipe out your entire account balance.
Beginners should use isolated margin mode — each trade's risk is clearly defined and controlled.
Adding Margin
When to Add Margin
When your position's unrealized losses grow and the margin approaches the maintenance level, the system sends a warning. You can choose to add margin to avoid forced liquidation.
How to Add Margin
Isolated Margin Mode:
- Find the "Add Margin" button in the position details
- Enter the amount to add
- After confirmation, your margin increases and the liquidation price moves further away
Cross Margin Mode: Simply deposit more funds into your futures account. The account balance automatically serves as margin.
Add Margin or Stop-Loss?
While adding margin can prevent liquidation, if the price keeps moving against you, the additional margin will also be lost. Sometimes cutting your loss with a stop-loss is wiser than adding margin.

Margin Management Tips
Control Initial Margin Ratio
Keep each position's margin to no more than 10-20% of your total futures account balance. This way, even several consecutive losing trades won't quickly deplete your funds.
Keep Reserves
Don't use all your funds for positions. Keep at least 50% in reserve for adding margin when needed.
Calculator Tool
The Binance App provides a futures calculator that quickly computes initial margin, PNL, and liquidation prices. Find the calculator icon on the futures trading page.
FAQ
What currency is used for margin?
USDT perpetual contracts use USDT as margin. Coin-margined contracts use the corresponding cryptocurrency (e.g., BTC contracts use BTC).
What's the difference between initial and maintenance margin?
Initial margin is the minimum required to open a position. Maintenance margin is the minimum needed to keep the position from being force-liquidated. Maintenance margin is much lower than initial margin.
Can I see margin changes in real time on the Binance App?
Yes. Position details show current margin, margin ratio, and estimated liquidation price in real time.
What does a negative margin ratio mean?
A negative margin ratio indicates forced liquidation has been triggered. Under normal circumstances, you'll receive a warning before this happens.
Safety Tips
- Always calculate required margin and liquidation price before opening a position
- Use isolated margin mode to cap the maximum loss on each trade
- Keep each position's margin to 10-20% of your total funds
- When approaching liquidation, decide calmly: add margin or cut losses
