Crypto leverage and liquidation: how the maths works on exchanges and CFDs

Leverage lets you control a crypto position larger than the money you put up, and liquidation is what happens when your losses eat through that money: the platform closes the position for you. On a crypto exchange the liquidation price is set by your leverage and the maintenance margin rate, so a 10x long is liquidated after a fall of a little under 10%. On a crypto CFD offered to EU retail clients, leverage is capped at 2:1 and the broker must start closing positions once account equity falls to half of the required margin.

The two systems share a vocabulary but behave differently, and confusing them is one of the more expensive mistakes in crypto trading. This guide works through the arithmetic for both, with illustrative numbers, and then covers what the formulas leave out. For the broader picture of why crypto moves so much, read crypto volatility and risk first; this guide stays with the mechanics.

Leverage, margin and effective leverage

Leverage is a ratio between the value of a position and the money set aside to hold it. At 10x, a $10,000 position needs $1,000 of margin. At 2:1, the same position needs $5,000. The general principles are the same as in forex, which the leverage and margin guide covers in detail.

Three numbers are worth separating:

• Notional value: the full value of the position, quantity times price. A position of 0.2 BTC at an illustrative $50,000 has a notional value of $10,000.
• Initial margin: the amount locked when you open the position. It equals notional value divided by leverage.
• Maintenance margin: the minimum equity the platform requires to keep the position open. Fall below it and the position is liquidated or closed out.

The number that actually describes your risk is effective leverage: total notional value of open positions divided by account equity. If you hold $10,000 of bitcoin exposure in an account worth $20,000, your effective leverage is 0.5x, even if the platform let you choose 10x on the order ticket. If you hold $10,000 of exposure with $1,000 in the account, it is 10x whatever the setting says. Platforms advertise maximum leverage; your account only experiences effective leverage.

How liquidation works on a crypto exchange

Most crypto exchanges that offer leveraged trading (on margin, futures or perpetual contracts) use a maintenance margin rate, often a fraction of a percent for the largest coins at small position sizes, rising in tiers as the position gets larger. When your position's equity falls to the maintenance requirement, the exchange's liquidation engine takes over the position and closes it.

Isolated and cross margin

Exchanges usually offer two modes, and the choice changes the liquidation price.

• Isolated margin: only the margin you assign to that position can be lost on it. The liquidation price is fixed by that margin and the leverage. When it is hit, you lose the position's margin, but the rest of your balance is untouched.
• Cross margin: the whole available balance supports every open position. The liquidation price moves further away because more money stands behind the trade, but a liquidation can now take most of the account, and a loss on one position reduces the buffer for all the others.

Cross margin is not safer by default. It postpones liquidation by putting more money at risk. Isolated margin limits the loss per position but brings the liquidation price closer.

The approximate liquidation formula

For an isolated long position, ignoring fees and funding, the liquidation price is approximately:

Liquidation price (long) ≈ Entry price × (1 − 1/leverage + maintenance margin rate)

For a short, it is approximately:

Liquidation price (short) ≈ Entry price × (1 + 1/leverage − maintenance margin rate)

The intuition is simple. At 10x, your margin is 10% of the position, so a 10% adverse move would wipe it out entirely. The exchange does not wait for zero; it liquidates when the remaining equity reaches the maintenance level, so the liquidation comes slightly before the full 10%. Each exchange publishes its own formula, which may include fees, funding and tiered maintenance rates, and the liquidation price shown on the order ticket is the one that applies.

Worked example: a 10x isolated long

The numbers are illustrative.

• You buy 0.2 BTC at $50,000 with 10x leverage in isolated mode.
• Notional value: 0.2 × $50,000 = $10,000.
• Initial margin: $10,000 ÷ 10 = $1,000.
• Maintenance margin rate: 0.5% of position value.

The position is liquidated when equity equals maintenance margin. Equity is $1,000 minus the loss, and the loss is 0.2 × (50,000 − price). Solving for the price where equity equals 0.5% of the position value gives about $45,226. The shortcut formula gives $45,250, which is close enough for planning.

That is a fall of about 9.5%. In bitcoin, a 9.5% move inside a day is not rare, and for smaller coins it is routine. At liquidation you lose almost all of the $1,000 margin, plus a liquidation fee on many exchanges.

The same short position (sold at $50,000 with 10x) would be liquidated at roughly $54,700, a rise of about 9.5%.

How the distance shrinks as leverage rises

Using the shortcut formula with a 0.5% maintenance rate and an entry of $50,000 (illustrative):

• At 2x, a long is liquidated near $25,250, a fall of about 49.5%.
• At 5x, near $40,250, a fall of about 19.5%.
• At 10x, near $45,250, a fall of about 9.5%.
• At 20x, near $47,750, a fall of about 4.5%.
• At 50x, near $49,250, a fall of about 1.5%.
• At 100x, near $49,750, a fall of about 0.5%.

At 100x, the spread, a single funding payment and an ordinary minute of noise can be enough. High-leverage settings are not a stronger version of a normal trade; they are a different bet, mostly on the price not wobbling.

What happens at the moment of liquidation

The liquidation engine usually takes over your position and tries to close it in the market. If it closes at a better price than the bankruptcy price (the price at which your margin would be exactly zero), the difference typically goes into the exchange's insurance fund rather than back to you. If the market moves too fast and the position closes beyond the bankruptcy price, the insurance fund covers the shortfall. When the fund cannot, some exchanges use auto-deleveraging, which closes part of the positions of traders on the winning side. The details differ by venue; the point is that your loss at liquidation is normally your whole isolated margin, not just the distance to the maintenance level.

Mark price, not last traded price

Most derivatives exchanges trigger liquidation from a mark price, an index built from several spot exchanges, rather than from the last trade on their own book. This reduces liquidations caused by a single erratic trade. It also means a chart of last traded prices may not show the level that liquidated you, which confuses people reviewing what happened.

How margin close-out works on an EU crypto CFD

A crypto CFD with an EU-regulated broker works on a different system. Under the ESMA product intervention measures, which national regulators have made permanent in their own rules, retail clients face a leverage cap of 2:1 on CFDs referencing cryptocurrencies, a 50% margin close-out rule applied per account, and negative balance protection. The ESMA leverage limits guide explains where these rules come from.

The close-out rule works on the whole account: when account equity falls to 50% of the total initial margin required for open positions, the broker must close one or more positions. There is no per-position liquidation price in the exchange sense, although the platform will usually show a margin level percentage, and your broker may also issue a margin call before close-out. The margin call and stop-out guide explains margin level in general.

Worked example: four position sizes on the same account

The figures are illustrative, and spread, financing and fees are ignored to keep the arithmetic clear.

You deposit €5,000. At 2:1, the margin required is 50% of the position's value. The close-out threshold is equity equal to half that margin.

1. €10,000 position (the maximum at 2:1). Margin is €5,000; close-out happens when equity falls to €2,500. That needs a loss of €2,500, which on a €10,000 position is a 25% fall.
2. €8,000 position. Margin is €4,000; close-out at equity of €2,000. That needs a loss of €3,000, a 37.5% fall.
3. €5,000 position (effective leverage 1x). Margin is €2,500; close-out at €1,250 of equity. That needs a loss of €3,750, a 75% fall.
4. €4,000 position. Margin is €2,000; close-out at €1,000 of equity. That needs a loss of €4,000, which is the entire position value. In practice the margin rule cannot close it out; the risk is simply the €4,000 exposure.

The general rule for a single long position: the percentage fall that triggers close-out equals (equity minus a quarter of the position value) divided by the position value. The less of the 2:1 allowance you use, the further away close-out sits. The crypto margin calculator shows the margin for any size, and the crypto position size calculator works backwards from a stop to a size.

Why a 25% buffer is still thin

A 25% fall in bitcoin over a few days has happened many times, and smaller coins can fall that far within hours. The close-out level is also not a stop-loss price. The broker closes positions at the next available price, and if the CFD was not being quoted (for example over a weekend break or a maintenance window) the reopening price can be well beyond the threshold. That is gap risk, and the planned guide to bitcoin trading hours and weekends covers when crypto CFDs are and are not quoted.

Negative balance protection means an EU retail client cannot lose more than the money in the account. It does not limit the loss to the close-out threshold. In a severe gap, a fully leveraged account can lose close to everything.

Exchange liquidation and CFD close-out side by side

Put in plain sentences, the main differences are these:

• Maximum leverage. Many crypto exchanges outside the EU retail perimeter advertise 50x, 100x or more. An EU retail crypto CFD is capped at 2:1.
• Scope. Exchange liquidation is usually calculated per position (isolated) or per margin account (cross). CFD close-out is calculated across the whole CFD account.
• Trigger. Exchanges use a maintenance margin rate and usually a mark price. CFD brokers use the 50% of initial margin threshold and their own quoted price, normally the bid for longs and the ask for shorts.
• What you lose at the trigger. On an exchange, usually the whole isolated margin plus a fee. On a CFD, the loss to the point of close-out, which can be larger after a gap, but never below zero for a retail client.
• Protection. EU-authorised CFD providers must apply the ESMA rules and are supervised. Offshore exchanges offering high leverage to EU residents are often not authorised to do so, and using them means giving up those protections. Check any provider on the regulator registers.

In February 2026, ESMA published a statement reminding firms that derivatives marketed as perpetual futures can fall within the CFD intervention measures, regardless of their commercial name, which would bring the leverage limits, close-out rule and negative balance protection with them. The perpetual futures and funding rates guide explains what that means in practice. In the UK, the FCA has banned the sale of crypto derivatives, including CFDs, to retail consumers since January 2021.

Sizing so that liquidation never becomes the stop

The most useful mindset shift is to treat the liquidation or close-out level as a failure state, never as your planned exit. A properly sized trade is closed by your own stop-loss long before the platform intervenes.

Worked example: working backwards from a stop

The figures are illustrative.

• Account equity: €5,000. You decide to risk 1% per trade, so €50.
• You want to buy a bitcoin CFD at €50,000 with a stop at €46,000, 8% below entry. Choosing that level is a separate question; the planned guide to crypto stop-loss placement covers it.
• A €4,000 move per bitcoin on a €50 risk gives a position of €50 ÷ €4,000 = 0.0125 BTC.
• Notional value: 0.0125 × €50,000 = €625. Margin at 2:1: €312.50.

Effective leverage is €625 ÷ €5,000, about 0.125x. The close-out threshold is far beyond the stop, so the stop decides the outcome, not the margin rule. If the price gapped through the stop by another 10%, the loss would be around €112 instead of €50: unpleasant, but survivable. The position sizing guide explains the method step by step.

Compare a trader with the same €5,000 who opens the full €10,000 because the platform allows it. An 8% fall costs €800, 16% of the account, on a single trade. The stop is identical; the size is what changed.

Why fees and funding move the liquidation price

On an exchange, every funding payment you pay on a perpetual, and every trading fee, comes out of the position's margin in isolated mode, so the liquidation price creeps towards the current price the longer you hold. On a CFD, overnight financing comes out of account equity and pulls the close-out threshold closer in the same way. The crypto CFD overnight fees guide shows how quickly those charges add up.

Liquidation cascades

Because so many traders use leverage, liquidations cluster. A fall triggers liquidations of long positions, the liquidation engines sell into the market, the selling pushes the price lower, and the next band of liquidation prices is hit. The reverse, a short squeeze, happens on the way up. These cascades are one reason crypto moves often overshoot and then partly reverse within minutes.

For a leveraged trader, a cascade has two consequences. First, a level you thought was safe can be reached by a move that has little to do with news and a lot to do with other people's positioning. Second, order books thin out during a cascade, so stops and liquidations fill further from their trigger. The planned guide to crypto order books and liquidity explains why.

Common mistakes

• Choosing leverage on the order ticket rather than sizing the position. The leverage setting on an exchange changes margin and liquidation price, but your loss in currency depends on position size. Decide the size from the risk you can accept, then check the liquidation price is far beyond your stop.
• Treating the liquidation price as a stop-loss. It is the price at which you lose the margin, often plus a fee. A stop should be where your trade idea is wrong, well before that.
• Using cross margin to avoid liquidation. It delays liquidation by putting the whole balance behind every position. One bad trade can then take the account.
• Adding margin to a losing position to push the liquidation price away. This increases the amount at risk on a trade that is already wrong. Sometimes it works; when it does not, the loss is larger.
• Assuming the close-out level on a CFD is the worst case. Gaps and fast markets mean the fill can be far beyond the threshold.
• Ignoring funding and financing. They erode margin quietly, and a long hold at high leverage can be liquidated by costs alone combined with a modest move.
• Using unauthorised offshore venues for higher leverage. You lose regulatory protections, negative balance protection may not apply, and if the platform fails, recovering money can be slow or impossible.

Most retail CFD accounts lose money: brokers' own disclosures typically show between about 61% and 89% of retail accounts losing, and ESMA's 2018 analysis found 74% to 89%. The why most retail CFD traders lose guide looks at the reasons, and leverage is near the top of the list. Crypto exposure, leveraged or not, can lose you all of your money.

Frequently asked questions

How do I calculate my liquidation price on a crypto exchange?

For an isolated long, a good approximation is entry price × (1 − 1/leverage + maintenance margin rate); for a short, entry price × (1 + 1/leverage − maintenance margin rate). At 10x with a 0.5% maintenance rate, that puts liquidation about 9.5% from entry. Exchanges include fees, funding and tiered maintenance rates in their own calculation, so rely on the liquidation price the platform shows for the actual position.

What leverage can EU retail clients use on crypto CFDs?

The maximum is 2:1, meaning margin of at least 50% of the position's value. This comes from the ESMA product intervention measures adopted by national regulators, which also require a 50% margin close-out per account and negative balance protection for retail clients. Professional clients can be offered more leverage but lose these protections.

What is the difference between liquidation and margin close-out?

Both are forced closures when equity runs too low. Liquidation is the exchange term and is usually calculated per position from a maintenance margin rate. Margin close-out is the CFD term under the ESMA rules: the broker must close positions once account equity falls to 50% of the margin required for all open positions.

Can I lose more than my deposit on crypto leverage?

As an EU retail client with a regulated CFD provider, negative balance protection means you cannot lose more than the money in your account. On many crypto exchanges, isolated margin limits the loss to that position's margin, while cross margin can use your whole balance. Outside regulated retail CFDs, read the platform's terms rather than assuming protection exists.

Does lower leverage mean lower risk?

Lower effective leverage means a larger move is needed to reach liquidation or close-out, and a smaller loss in currency for the same price move. It does not remove risk: an unleveraged crypto position can still fall by most of its value. Risk is set by position size relative to your account and by where you exit.

Why was I liquidated when the chart never touched my liquidation price?

Exchanges usually trigger liquidations from a mark price built from several spot markets, not from the last trade on their own book, and CFD brokers close out longs on their bid price. Funding payments and fees also move the liquidation price closer over time. Check the platform's mark price history and your position's margin record.
