Bitget futures: Tiered maintenance margin explained
In crypto futures trading, Bitget uses a tiered maintenance margin system based on position size to balance position safety with capital efficiency, especially during periods of high market volatility. This article explains how the system works, how margin requirements are calculated, and how to apply it with practical examples.
Overview of the position tiered maintenance margin system
The tiered maintenance margin system dynamically adjusts the maintenance margin rate (MMR) based on the size of your position. As your position grows, the MMR increases, helping reduce risk in high-leverage environments. Bitget implements this system by dividing positions into tiers, each with its own MMR, to ensure proper risk control across all position sizes.
How it works
Bitget applies a position tiered system where each position size range corresponds to a tier with a specific MMR. Below is an example of the BTCUSDT USDT-M futures tier structure:

As your position moves into a higher tier, the system automatically increases the required maintenance margin. This helps ensure your account can withstand market volatility. You can view position tier information on the futures trading page, or by clicking here.
Calculation formula
Here's how maintenance margin is calculated:
Maintenance margin = position value × MMR
Position value = futures position size × contract multiplier × current market price
Initial margin = position value ÷ leverage
Example calculation
Example: BTCUSDT futures trading
Suppose you hold a 2 BTC position in BTCUSDT perpetual futures at a market price of 50,000 USDT with 10x leverage. Here's how the margin is calculated:
Position value = 2 x 50,000 = 100,000 USDT
Based on the tiered table, this falls under tier 1 (0–150,000 USDT), with a maximum leverage of 125x and an MMR of 0.4%.
Initial margin required = 100,000 ÷ 125 = 800 USDT
Maintenance margin = 100,000 × 0.4% = 400 USDT
To open this position, you need at least 800 USDT in initial margin. To avoid liquidation, your account balance must stay above 400 USDT.
Why Bitget uses position tiered maintenance margin system?
Bitget's tiered maintenance margin system offers the following benefits:
• Dynamic risk management: Larger positions require higher margin, which reduces liquidation risk.
• Capital efficiency: Lower position tiers benefit from lower margin requirements, maximizing fund utilization.
FAQ
Q: How do I know which tier my position is in?
A: Visit the position tier introduction page or check the position management page to view your position's current tier and corresponding MMR in real time.
Q: Will a tier change affect existing positions?
A: Yes. If your position size increases and crosses into a higher tier, the system will automatically apply the new margin requirement. Make sure your account balance is sufficient to meet the updated maintenance margin.
