Who This Is For
This guide is for intermediate crypto traders who use MEXC Futures and want to understand exactly how their positions get liquidated so they can manage risk better.
What You’ll Need
- An active MEXC Futures account with at least one open position
- The position size (contracts or USDT amount) and entry price
- The leverage multiplier you’re using (e.g., 5x, 10x, 25x, 100x)
- The initial margin (IM) and maintenance margin (MM) rates for the pair
- A basic calculator — or the MEXC app’s built-in liquidation price tool
Key Takeaways
- Liquidation price depends on your entry price, leverage, and the maintenance margin ratio — not just your position size.
- For long positions, liquidation price = entry price × (1 – (initial margin / entry price) + maintenance margin ratio). For shorts, it’s the inverse.
- MEXC uses a partial liquidation mechanism: you lose only part of your position, not all of it, if you hit the liquidation price.
- Always factor in the funding rate and your available balance — they can shift your liquidation price in real time.
Step 1: Understand the Core Formula
Before you punch numbers into a calculator, you need to know the math behind it. MEXC Futures uses a standard cross-margin or isolated-margin model depending on your settings. The liquidation price formula for a long position is:
Liquidation Price (Long) = Entry Price × (1 – (Initial Margin / Entry Price) + Maintenance Margin Ratio)
For a short position, it flips:
Liquidation Price (Short) = Entry Price × (1 + (Initial Margin / Entry Price) – Maintenance Margin Ratio)
Sounds like a lot, right? It’s simpler than it looks. The key variables are your entry price, the leverage you chose, and the maintenance margin ratio — which is set by MEXC and varies per trading pair. For example, BTC/USDT perpetuals typically have a maintenance margin ratio around 0.5% at 100x leverage.
Step 2: Gather Your Position Details from MEXC
Log into your MEXC Futures account and open the “Positions” tab. You’ll see your entry price, position size, and leverage. Write these down. Let’s use a concrete example:
- Position: Long 0.1 BTC
- Entry Price: $30,000
- Leverage: 10x
- Initial Margin: $300 (0.1 BTC × $30,000 / 10x)
- Maintenance Margin Ratio: 0.5% (for BTC/USDT at 10x)
Now plug those numbers into the long formula. The liquidation price is roughly $27,150. That means if BTC drops to $27,150, your position gets liquidated. You lose your initial margin of $300. But with 10x leverage, a 9.5% move against you wipes out your entire margin. That’s the brutal reality of leverage.
Remember, MEXC uses a tiered margin system. Higher leverage means a higher maintenance margin ratio. So at 100x, the maintenance margin ratio might be 1.0% — making your liquidation price much closer to your entry. Investopedia explains maintenance margin in detail here.
Step 3: Use MEXC’s Built-in Liquidation Price Calculator
You don’t have to do the math manually every time. MEXC offers a liquidation price calculator right inside the trading interface. Here’s how to access it:
- Open the Futures trading page for your chosen pair (e.g., BTC/USDT).
- Click on the “Calculator” icon next to the order entry box.
- Select “Liquidation Price” from the dropdown menu.
- Enter your entry price, leverage, and position size.
- The tool instantly shows your liquidation price and the percentage move needed to hit it.
This is a lifesaver for new traders. You can test different leverage levels without risking real money. For instance, if you lower leverage from 10x to 5x, your liquidation price drops to around $28,575 — giving you more breathing room. The trade-off is smaller potential profits.

One thing to watch: the calculator assumes no funding rate. In reality, funding payments — which occur every 8 hours on MEXC — can eat into your position margin and push your liquidation price closer. So always leave a buffer of at least 5-10% above the calculated liquidation price.
Step 4: Account for Real-Time Variables
The liquidation price you calculate is a starting point, not a fixed number. Several things can change it while your position is open:
- Funding rate payments: If you’re long and the funding rate is positive, you pay shorts. That reduces your margin and moves your liquidation price closer.
- Partial liquidations: MEXC doesn’t close your entire position at once. It uses a partial liquidation mechanism — if you hit the liquidation price, only part of your position gets closed. The rest remains open with a new, higher liquidation price. This can save you from a total loss.
- Adding margin: You can manually add margin to your position in isolated mode. This pushes your liquidation price further away. It’s a common tactic during volatile moves.
Let’s say BTC drops from $30,000 to $28,000 — above your calculated liquidation price of $27,150. But if funding rates have been negative for days and you’ve paid $50 in funding, your effective margin is now $250. That could push your liquidation price to $27,800. You’d be liquidated even though BTC never hit your original target. So always monitor funding rates in MEXC’s “Funding Rate” tab. CoinDesk has a solid primer on funding rates.
Pro tip: Set a stop-loss order at 2-3% above your liquidation price. That way, you exit the trade before the exchange does it for you — and you might save a portion of your margin.
Common Pitfalls and Risks
⚠️ Risk: Ignoring the maintenance margin ratio. Many traders assume liquidation price is just entry price divided by leverage. But the maintenance margin ratio adds a fixed percentage that can be significant — especially at high leverage. Fix: Always use the exact formula or MEXC’s calculator. Don’t guess.
⚠️ Risk: Not accounting for cross-margin vs. isolated-margin. In cross-margin mode, your entire account balance acts as margin. That means one losing position can liquidate your other positions too. Fix: Use isolated margin for high-risk trades. It caps your loss to just that position’s margin.
⚠️ Risk: Overlooking the funding rate’s impact. Funding payments are small but they add up. Over a week, they can reduce your margin by 1-2%. That’s enough to push you into liquidation during a sideways market. Fix: Check the funding rate history before opening a position. Avoid holding positions with consistently high funding rates.

What Next?
Now that you can calculate liquidation price on MEXC Futures, practice with small positions — like 0.01 BTC at 5x leverage — before scaling up.
