Formula
Leverage = Total exposure ÷ CapitalHow it works
Real leverage is a division: total exposure over capital. It is not the number the broker advertises — that is the maximum they allow — but the one you are actually running right now, and it is almost always lower than people think or far higher than they admit.
Margin is a different thing, and mixing the two is where most of the scares come from. Margin is the slice of your capital the broker locks while the position is open; it is exposure divided by the maximum leverage. You can have plenty of free margin and still be levered 20 times, because margin measures what the broker holds and leverage measures what the market can do to you.
What you get
- Required margin and notional exposure
- Effective vs. offered leverage
- Forex, crypto, CFDs and futures
Worked example
A $5,000 account. A 40,000-unit EUR/USD position (0.40 lots) opened at a 1.0850 quote, with a broker offering 1:30 leverage.
- Notional exposure: 40,000 × 1.0850 = $43,400.
- Real leverage: $43,400 ÷ $5,000 = 8.68 times.
- Required margin: $43,400 ÷ 30 = $1,446.67.
- Free margin: 5,000 − 1,446.67 = $3,553.33.
Real leverage 8.68x, with $1,446.67 locked and $3,553.33 free.
The free margin looks comfortable and the leverage is not: at 8.68 times, a 1% adverse move — $434 — takes 8.7% of the account. Margin tells you when the broker closes you out; leverage tells you how much it hurts before you get there.
The leverage in the brochure and the leverage you are running
The number a broker advertises is a ceiling, not a position. "1:500" means it will let you open up to five hundred times your capital, not that you are trading that way. Your real leverage is a division that depends on two figures of your own: the notional exposure you have open and the account capital.
That distinction has an immediate practical consequence. A high ceiling does not raise risk by itself — if you size by risk, the size comes out the same at 1:30 as at 1:500 — but it does remove the brake that stopped you opening a position that was too big. The damage is not done by the leverage available: it is done by the leverage you choose to use.
In the European Union that ceiling is capped by asset class for retail clients, and the limits say a good deal about how the regulator rates the risk of each one:
| Asset class | Retail cap (ESMA) | Margin on notional |
|---|---|---|
| Major currency pairs | 1:30 | 3.3% |
| Other pairs, gold and major indices | 1:20 | 5.0% |
| Other commodities and non-major indices | 1:10 | 10.0% |
| Individual shares | 1:5 | 20.0% |
| Cryptocurrencies | 1:2 | 50.0% |
A broker regulated in the EU cannot offer you 1:500 on EUR/USD as a retail client. If it does, the entity opening your account is outside that perimeter, and that also changes what protection you have if something goes wrong.
From leverage to stop-out, step by step
The chain has four links and each one feeds the next. Leverage decides how much notional you open with your capital; the notional decides how much margin the broker holds; the margin held and your equity determine the margin level; and the margin level is what the broker watches to close you out.
With a $5,000 account and $43,400 of exposure you are at 8.68 times. The margin required at the 1:30 cap is $1,446.67, so you have $3,553.33 free. So far it all looks comfortable. What actually decides is another figure: how much the open positions can lose before equity falls to the stop-out threshold.
And that is where leverage shows. At 8.68 times, a 1% move against you is $434, 8.7% of the account. At 20 times it would be $1,000, 20%. The margin level would not have changed that much — the margin held grows in proportion — but the speed at which you approach the threshold certainly would.
That is the reading worth taking away: the margin level tells you when the broker closes you, and leverage tells you how much the road there hurts. An account can have a comfortable margin level and be two bad sessions from stop-out.
Why leverage does not enter the result
The result of a trade is (exit price − entry price) × quantity × contract multiplier. Leverage appears in no term of that formula, and putting it in is one of the most expensive calculation errors there is: on a future with a multiplier of 50, confusing the two multiplies the result by fifty.
What leverage does change is how much quantity you could afford to open. Once open, each unit is worth what it is worth and moves what it moves. That is why the percentage gain on capital rises with leverage — the same move over more units — without the P&L formula mentioning it.
The multiplier, on the other hand, is part of the result: it is the contract size. A point of the E-mini S&P 500 is worth $50 because the contract represents 50 times the index, just as a forex lot represents 100,000 units of the base currency. They are the same idea under another name, and neither of them is leverage.
How to use it
- Enter your inputs: the terms of the formula (capital, risk, prices and stop).
- The calculator applies the formula and returns the result in your instrument's units.
- Check the breakdown before trading: anything that cannot be computed is shown empty, never as zero.
Frequently asked questions
What is my real leverage on a EUR/USD position?
Divide notional exposure by your capital. 40,000 units of EUR/USD at 1.0850 is $43,400 of exposure; on a $5,000 account that is 8.68 times, even if your broker advertises 1:30. This is the number that matters, not the brochure one.
What leverage is reasonable in forex?
Whatever falls out of sizing by risk, which in practice rarely exceeds 10 times for an account that survives losing streaks. Leverage should not be chosen: it should be the result of having chosen the stop and the risk percentage. If the calculation returns 40 times, the problem is not the leverage, it is the size.
Is 1:500 better than 1:30?
Not for trading; it only lets you lock less margin for the same position. At 1:500 the margin on that $43,400 drops from $1,446 to $87, and the only thing that really changes is that you can now open a position six times larger with the same money. The loss per pip is identical either way.
Does leverage enter the calculation of my profit?
No. A trade’s result is (exit − entry) × quantity × contract multiplier, and leverage appears nowhere in that formula. What leverage changes is what quantity you could afford to open, not what each unit you opened is worth.
How do margin, margin call and stop-out relate?
Margin level is equity divided by used margin, as a percentage, and it is what the broker watches. Below 100% the warning usually arrives; below 50%, the forced closing of positions, which is the stop-out. High leverage does not trigger a stop-out on its own: what triggers it is open losses eating the equity.
What leverage does European regulation allow?
ESMA caps it for retail clients by asset class: 1:30 on major currency pairs, 1:20 on other pairs, gold and major indices, 1:10 on other commodities, 1:5 on shares and 1:2 on crypto. An EU-regulated broker cannot offer you 1:500 on EUR/USD as a retail client, and if one does it is because the entity opening your account sits outside that perimeter.
