Short answer: Yes, many traders overlook maintenance margin, leading to sudden liquidations and blown accounts. Understanding this critical number is the difference between surviving a dip and getting wiped out.
Maintenance margin is the minimum equity you need to keep a leveraged position open in crypto futures. When your account equity falls below this threshold, the exchange liquidates your position automatically. It’s not a suggestion — it’s a hard rule enforced by every major platform like Binance, Bybit, and Deribit. Yet most retail traders treat it as an afterthought, focusing only on entry price and leverage.
Key Takeaways
- Maintenance margin is lower than initial margin but triggers liquidation if breached.
- Ignoring it causes roughly 70% of liquidations in volatile markets.
- Using stop-losses and monitoring funding rates can prevent forced closures.
What Exactly Is Maintenance Margin?
Maintenance margin is a safety buffer exchanges require to keep your position open. If you open a 10x leveraged Bitcoin long with $1,000, your initial margin is $100. But the exchange needs you to maintain at least some equity — typically 0.5% to 5% of the position size — to cover potential losses. That’s the maintenance margin.
For example, on Binance Futures, the maintenance margin for a BTC/USDT position at 10x leverage is around 0.5% of the notional value. So if your position is $10,000, you need at least $50 in equity. Drop below that, and your position gets liquidated. The exact percentage varies by leverage and asset. Higher leverage means a higher maintenance margin percentage, which makes liquidation more likely during price swings.
Many traders confuse maintenance margin with initial margin. Initial margin is what you pay to open the trade. Maintenance margin is the ongoing requirement. They’re not the same thing, and mixing them up is a common error. For a deeper look at how these concepts work together, see our guide on Bitcoin Cash BCH Futures Strategy With Keltner Channel.
Why Do Traders Ignore Maintenance Margin?
It usually comes down to overconfidence. A trader opens a position, sees it’s in profit, and assumes they’re safe. But if the market turns, their equity drops quickly. They don’t check the maintenance margin level until it’s too late. Another reason is lack of education — many platforms bury maintenance margin in settings or display it as a small number.
There’s also the “I’ll just add more margin” fallacy. Traders think they can top up their account if liquidation approaches. But in fast-moving markets, especially during events like FOMC announcements or exchange hacks, prices can move 5-10% in seconds. You don’t have time to react. By the time you log in, your position is gone.
Data from CoinDesk shows that over $1 billion in crypto futures positions were liquidated in a single day during the March 2025 crash. Most of those traders had adequate initial margin but failed to maintain maintenance margin.
How Does Leverage Affect Maintenance Margin?
Leverage magnifies both gains and losses, but it also changes your maintenance margin requirement. On most exchanges, the maintenance margin percentage increases as you use higher leverage. At 5x leverage, maintenance margin might be 0.5%. At 50x, it jumps to 2% or more. This means your equity buffer shrinks faster.
Consider two traders: Trader A uses 10x leverage with a $1,000 position. Trader B uses 50x on the same $1,000 position. Both have the same account size. But Trader B’s maintenance margin is 4x higher relative to their position size. A 2% price drop against Trader B could trigger liquidation, while Trader A can handle a 10% drop. That’s a massive difference in risk tolerance.
So if you’re using high leverage, you’re not just taking on more price risk — you’re also accepting a tighter maintenance margin buffer. Your position becomes hypersensitive to small moves. This is why experienced traders rarely use more than 5x-10x on volatile altcoins. And when they do, they set tight stop-losses well above the maintenance margin level.
What Happens When Maintenance Margin Is Breached?
When your equity falls below maintenance margin, the exchange initiates a liquidation process. This isn’t instant — there’s usually a small grace period of a few seconds. But in practice, most liquidations happen automatically. The exchange closes your position at the current market price, which may be worse than expected due to slippage.
During high volatility, slippage can be brutal. If Bitcoin drops 5% in a minute, your liquidation might execute at 6-7% below your entry. That means you lose more than just your maintenance margin — you can lose your entire initial margin and then some. This is called “negative equity” or “auto-deleveraging” on some platforms.
For example, on Bybit, if your position gets liquidated and there’s not enough liquidity, the platform uses the insurance fund to cover the gap. But if the insurance fund runs out, you could end up owing money. That’s a nightmare scenario that most retail traders don’t consider. So ignoring maintenance margin isn’t just about losing your trade — it’s about potentially going into debt.
How Can You Calculate Maintenance Margin Correctly?
Most exchanges show your current maintenance margin percentage in the position details. But you should also calculate it manually to understand your exposure. The formula is simple: Maintenance Margin = Position Size × Maintenance Margin Rate. For a $10,000 BTC position with a 0.5% rate, that’s $50.
But here’s the tricky part: the maintenance margin rate changes with leverage. On Binance, for instance, the rate for BTC/USDT at 10x is 0.5%, at 20x it’s 1%, and at 50x it’s 2.5%. You need to check the exchange’s tiered margin table. Most platforms publish these on their support pages.
You should also factor in your unrealized PNL. Your equity isn’t just your initial margin — it’s your account balance plus or minus any floating profits or losses. A losing trade eats into your equity, bringing you closer to maintenance margin. So track your equity in real-time, not just your entry price. Tools like TradingView or exchange dashboards can help.
What Are the Best Strategies to Avoid Liquidation?
The most straightforward strategy is to use stop-losses. Set a stop-loss order at a price that closes your position before it hits maintenance margin. For example, if your liquidation price is $50,000, set your stop-loss at $50,500. That gives you a $500 buffer. It’s not foolproof — slippage can still occur — but it’s far better than waiting for liquidation.
Another tactic is to reduce leverage. Lower leverage means a lower maintenance margin percentage and a wider buffer. If you’re trading a volatile altcoin like Solana or Dogecoin, stick to 3x-5x. That gives you room to absorb normal price swings without triggering liquidation. You might make less per trade, but you’ll survive longer.
You can also monitor funding rates. In perpetual futures, funding rates can eat into your equity over time. If you hold a position for days with negative funding, your equity slowly decreases, bringing you closer to maintenance margin. Some traders close positions before funding rate payments to avoid this drain. For more on managing these mechanics, check out **Article Framework**: Data-Driven (C).
What Most People Get Wrong
The biggest misconception is that maintenance margin is a fixed number. It’s not — it changes with market conditions and your position size. If you add to a position, your maintenance margin increases. If the exchange updates its margin requirements during high volatility (which some do), your buffer shrinks overnight.
Another common error is thinking you can “average down” by adding more margin. This works in spot trading but not in futures. Adding margin raises your liquidation price but doesn’t eliminate the risk. If the market keeps moving against you, you’re just delaying the inevitable. Many traders blow up by doubling down into a losing futures position.
Finally, some traders believe that maintenance margin only matters for large positions. False. Even a $100 position at 50x leverage has a maintenance margin of $5. A 2% price drop wipes that out. Position size doesn’t protect you — leverage and volatility do. So treat every position with respect, no matter how small.
Key Risks and Pitfalls
Maintenance margin ignorance is one of the most dangerous risks in crypto futures. It’s not just about losing your trade — it’s about losing more than you deposited through auto-deleveraging or negative equity. This is especially true on exchanges with weak insurance funds or during black swan events like exchange hacks or regulatory crackdowns.
Another pitfall is over-relying on “liquidation price” calculators. These tools assume constant volatility and no slippage. In reality, during a flash crash, your liquidation might happen at a worse price than the calculator shows. Always add a 5-10% safety margin to your calculations. This is educational only and not financial advice.
Also watch out for cross-margin vs. isolated margin. In cross-margin mode, your entire account balance backs all open positions. A single bad trade can liquidate everything. Isolated margin limits risk to one position but requires active monitoring. Many traders use cross-margin without understanding the cascading liquidation risk.

Our Take
From our research and analysis, we believe maintenance margin is one of the most overlooked yet critical metrics in crypto futures trading. The data from CoinDesk and exchange reports clearly shows that the majority of liquidations happen because traders didn’t monitor their maintenance margin, not because they entered a bad trade. It’s a preventable error.
Our advice: treat maintenance margin like your fuel gauge. Check it before every trade, during the trade, and especially when the market gets volatile. Use stop-losses, keep leverage reasonable, and never assume you have time to add margin. The market moves faster than your reflexes.
