When someone tells me an account offers 5x leverage, my first question is not how large a position I can open. It is what kind of product I am trading.
In a stock margin account, the broker may lend cash to buy securities. In a futures account, margin is collateral rather than a loan for the contract’s notional value. A CFD also uses collateral, but its pricing, financing and close-out rules come from the derivative agreement. Crypto spot margin and perpetual contracts add their own borrowing or funding mechanics.
The word margin appears in all of them. The money does not work the same way.
Margin trading means using cash or other eligible collateral to control a position larger than the amount paid upfront. This increases market exposure. It also allows a relatively small price move to produce a much larger percentage change in account equity.
What does margin mean in different markets?
Before I calculate anything, I identify the product. Stock and crypto spot margin can involve an actual loan. CFDs, futures and perpetual contracts create exposure through a derivative, with margin held as collateral.
The difference changes the holding cost. A securities loan accrues interest. A CFD may charge overnight financing. Listed futures use daily variation margin and have roll economics rather than loan interest on the full notional value. Perpetual contracts may exchange periodic funding payments.
A provider may use different terminology. The practical questions remain the same:
- Is there an actual loan?
- What amount is the profit or loss calculated on?
- What costs continue while the position stays open?
- What account level allows the provider to reduce or close the position?
The same word, five margin models
Start with the product. The leverage ratio does not explain where the exposure or holding cost comes from.
10x leverage is not a complete product description. Find the loan, collateral, close-out rule and holding cost first.
For the worked example, I use a securities margin loan. Its fixed debit balance makes the effect on equity easy to see.
A complete margin trading example
Assume I want $10,000 of stock exposure. I contribute $5,000, and the broker lends the other $5,000.
At the start:
| Account item | Amount |
|---|---|
| Market value of the stock | $10,000 |
| Broker loan | $5,000 |
| My account equity | $5,000 |
| Equity percentage | 50% |
The loan does not rise and fall with the stock price. My equity absorbs the market movement.
If the stock rises 20%
The position is now worth $12,000:
Account equity = Market value - Broker loan
$12,000 - $5,000 = $7,000The stock gained $2,000. Relative to my original $5,000 equity, that is a 40% gain before interest, commissions and tax.
If the stock falls 20%
The position is now worth $8,000:
$8,000 - $5,000 = $3,000 account equityThe position lost $2,000. That is a 40% loss on my original equity before costs.
The asset moved 20% in both examples. My equity moved 40% because the position was twice the size of my own contribution.

Start with the product. The leverage ratio does not explain where the exposure or holding cost comes from.
10x leverage is not a complete product description. Find the loan, collateral, close-out rule and holding cost first.
The four calculations I make before using margin
1. Notional exposure
Notional exposure is the full market value affected by a price move.
Notional exposure = Units x Market priceFor 100 shares at $100, the notional exposure is $10,000.
2. Required margin
If the product uses a fixed leverage ratio:
Required margin = Notional exposure / LeverageThe same calculation can use a margin rate:
Required margin = Notional exposure x Margin rateAt 5x leverage, the margin rate is 20%. A $10,000 position would therefore require $2,000 of initial margin in a simplified model.
The $2,000 is only the amount needed to open the position. Profit and loss are still calculated on $10,000 of exposure.
3. Profit or loss
For a simple linear position:
P&L = Notional exposure x Percentage price moveA 1% move on $10,000 is $100 before costs. If only $2,000 was posted as margin, the $100 move equals 5% of that initial margin.
4. Equity percentage or margin level
In a securities margin account:
Account equity = Market value - Debit balance
Equity percentage = Account equity / Market value x 100Forex, CFD and some crypto platforms often show a different metric:
Margin level = Account equity / Used margin x 100Suppose a CFD account has a $1,000 balance, an open loss of $200 and $250 of used margin. The account equity is $800, so:
Margin level = $800 / $250 x 100 = 320%If the open loss grows to $875 while used margin remains $250, equity falls to $125 and the margin level reaches 50%. That does not prove the position will close at 50%. The provider may use another threshold, recalculate used margin as prices change or close positions according to account-level rules.
I use the definitions and close-out levels in the account agreement, not a generic calculator from another provider.
Initial margin, maintenance margin and house margin
Initial margin is the amount required to open a position or add exposure.
Maintenance margin is the minimum equity required to keep the account or position open.
House margin is a stricter requirement set by the broker or provider. It can be higher than a regulatory or exchange minimum and may change when volatility, liquidity or concentration changes.
Futures add variation margin, the daily or intraday transfer of gains and losses through the clearing process. Futures margin is a performance bond. The broker is not lending the contract’s entire notional value.
These distinctions matter because an account can satisfy the opening requirement and still have very little room before maintenance or liquidation.
At what price would the stock example reach maintenance margin?
Return to the $10,000 stock position with a $5,000 broker loan.
Assume the maintenance requirement is 30%. For this simple one-position account, the market value that reaches maintenance is:
Maintenance threshold value = Broker loan / (1 - Maintenance rate)
$5,000 / (1 - 0.30) = $7,142.86At a market value of $7,142.86:
Account equity = $7,142.86 - $5,000 = $2,142.86
$2,142.86 / $7,142.86 = 30%The position has fallen about 28.6%, but my equity has fallen about 57.1% before interest and fees.
The calculation identifies a threshold, not a guaranteed warning price. A broker may apply a higher house requirement, change that requirement or sell assets without waiting for the client to respond.
Margin call and liquidation are not the same event
A margin call means the account no longer meets a required margin level. The provider may request additional funds, eligible collateral or a reduction in exposure.
Liquidation means positions or other account assets are sold or closed to reduce the deficiency. It may happen automatically and without a useful warning period.
The phrase “liquidation price” can sound more precise than it is. The displayed estimate may change with:
- maintenance requirements;
- accrued interest, financing or funding;
- commissions and liquidation fees;
- the value of collateral;
- other open positions;
- cross-margin offsets;
- risk tiers based on position size;
- changes to provider rules.
Liquidation normally occurs before the allocated margin reaches zero. Its purpose is to protect the provider against a deficit, not to wait until the trader has no equity left.
Cross margin vs isolated margin
Cross and isolated margin are common on crypto and some derivatives platforms. They are not universal settings for every margin account.
Isolated margin
Only the collateral allocated to one position supports that position under normal conditions. This makes the position-level risk easier to see.
It does not automatically guarantee that the allocated amount is the legal maximum loss. Auto-add settings, gaps, fees, liquidation mechanics and the account agreement still matter.
Cross margin
Eligible collateral is shared across several or all positions. Profits and spare equity elsewhere in the account can support a losing position.
That may delay liquidation of one trade. It also gives that trade access to more of the account. Correlated losses can consume the shared collateral together.
I compare the modes by checking how much of the account each position can consume. The label alone does not tell me that.
What does margin trading cost?
The cost depends on the product rather than the leverage number alone.
| Product | Costs to check |
|---|---|
| Stock margin loan | Loan interest, commission, spread and possible short-borrow fee |
| Crypto spot margin | Borrow interest, trading fees, spread and liquidation charges |
| CFD or rolling spot | Spread, commission, overnight financing and currency conversion |
| Listed futures | Commission, exchange and clearing fees, spread, market data and roll costs |
| Perpetual contract | Trading fees, spread, funding payments and liquidation charges |
Funding payments are associated with perpetual contracts, not standard dated futures. A dated futures price can trade above or below spot because of carry and market expectations, but that is not the same as a periodic funding transfer.
I calculate costs against notional exposure. A 0.10% charge on a $50,000 position is $50, even if the initial margin was only $5,000.
What margin does not solve
Margin can reduce the amount paid upfront. It may also make short exposure or a capital-efficient hedge possible when the product supports it.
But it does not make the market view more likely to be right. A short may still be hard to borrow or close. A hedge can introduce basis risk. And cash that looks available today may be needed later if losses grow or margin requirements rise.
The spot versus margin trading comparison covers ownership and borrowing in more detail. Spot trading and margin trading are not always opposites: a spot asset can be bought with borrowed funds, while a derivative can use margin without transferring ownership of the underlying asset.
The risks I check first
Losses can exceed the initial deposit
A gap, delayed liquidation or absence of negative balance protection can leave an account with a deficit. Protection depends on the product, legal entity and jurisdiction.
The broker can change the requirement
A higher house margin can create a deficiency even without a new trade. This is especially relevant for concentrated or volatile positions.
A stop order does not guarantee the exit price
A standard stop order usually becomes a market order after its trigger. In a gap or thin market, the fill can be worse than the stop price. A stop-limit can control the acceptable price but may not execute.
Several positions can be one leveraged bet
Five different instruments are not diversified if they all depend on the same currency, sector or market factor. Cross margin makes this account-level relationship more important.
Financing can outlast the trade idea
A position can move in the expected direction and still disappoint after interest, borrow fees, overnight financing or repeated funding payments.
Demo results do not reproduce liquidation
A demo can teach order entry and account terminology. It cannot prove live slippage, funding, queue position, margin changes or liquidation behavior.
