Understanding Maintenance Margin on Bybit

Maintenance margin on Bybit refers to the minimum amount of equity required to keep a leveraged position open. If your account equity falls below this threshold due to adverse price movements, your position becomes at risk of liquidation. This is a critical concept for traders using perpetual or futures contracts on Bybit, as it directly affects risk exposure and position sustainability.

Unlike initial margin—which is the collateral needed to open a position—maintenance margin ensures that your position remains active even when market conditions fluctuate. It acts as a buffer between your equity and the liquidation price. Bybit calculates this value dynamically based on leverage, position size, and contract type.

How Bybit Calculates Maintenance Margin

Bybit uses a tiered system where the maintenance margin rate varies depending on the position size. The larger the position, the higher the maintenance margin rate. This structure prevents excessive risk concentration and promotes stability in volatile markets.

For example:

• If you hold a position worth less than 50 BTC, the maintenance margin rate might be 0.5%.
• For positions between 50 and 250 BTC, the rate could increase to 1.0%.

The formula used by Bybit is:
Maintenance Margin = Position Size × Maintenance Margin Rate

This calculation happens in real time and updates as your unrealized profit or loss changes. You can view this value under the "Position" tab in your Bybit futures account.

Difference Between Isolated and Cross Margin Modes

Bybit offers two margin modes: isolated and cross. In isolated margin mode, each position has its own dedicated margin. If the maintenance margin for that specific position is breached, only that position gets liquidated—not affecting others.

In contrast, cross margin mode uses your entire wallet balance as collateral across all open positions. This means one losing position might draw from the equity of profitable ones to avoid hitting the maintenance margin threshold. While cross mode can delay liquidation, it also increases the risk of total account loss if multiple positions move against you.

Traders must choose carefully based on their strategy. Isolated mode offers better control per trade; cross mode offers flexibility but demands closer monitoring.

Step-by-Step Guide to Check Maintenance Margin on Bybit

To ensure you're aware of your maintenance margin levels, follow these steps:

• Log into your Bybit account and navigate to the Futures trading interface.
• Select the specific contract (e.g., BTCUSD) you want to inspect.
• Under the "Positions" section, locate the row corresponding to your open position.
• Look for the field labeled "Maintenance Margin"—this displays the current value in USDT or the base currency.
• Also check the "Leverage" and "Unrealized PNL" columns to understand how close your equity is to the maintenance level.

This process should be repeated regularly, especially during high volatility. Bybit also provides a Liquidation Price indicator next to the maintenance margin, giving you a visual cue of how much room you have before forced closure.

What Happens When Maintenance Margin Is Breached?

If your equity drops to or below the maintenance margin level, Bybit triggers an automatic liquidation process. The system closes your position at the prevailing market price to prevent further losses beyond the allocated margin.

Before liquidation occurs, Bybit sends a margin call notification via email or in-app alert. At this point, you can add more margin manually to increase your equity above the maintenance level and avoid closure. However, if no action is taken and the price continues moving against you, the position will be fully liquidated.

It’s important to note that partial liquidation may occur in large positions under certain conditions, where only a portion of the position is closed to bring the margin back above the required level.

Frequently Asked Questions

Can I change the maintenance margin rate on Bybit?

No, the maintenance margin rate is predefined by Bybit based on position size and asset type. Traders cannot modify this rate manually. However, adjusting leverage or reducing position size can effectively lower the required maintenance margin.

Does maintenance margin include fees?

Yes, Bybit factors in potential trading fees when calculating the maintenance margin. These fees are deducted from your available equity, which can influence how close you are to the liquidation threshold.

Is maintenance margin the same for all cryptocurrencies on Bybit?

No, different assets have different maintenance margin rates. For instance, BTC and ETH may have lower rates due to higher liquidity, while altcoins like SOL or DOGE may carry higher rates because of increased volatility.

How often does Bybit update maintenance margin values?

Bybit updates maintenance margin in real time as your unrealized PNL changes. This means every tick in price movement affects your equity and recalculates the margin requirement instantly. Traders should monitor this continuously during active trades.
