Forex Margin Calculator: DFSA and FSRA Leverage Caps

How to use this calculator

Choose the instrument, enter the position size in standard lots, and pick the account currency. The leverage cap shown is not a broker's offer; it is the DFSA (DIFC) or FSRA (ADGM) ceiling for that asset class, applied automatically and displayed read-only beside the inputs. The calculator then displays the notional value, the initial margin the broker must collect, and the equity level where forced close-out begins.

I want to be clear: margin is not a fee. It is equity set aside while the position is open, and it returns when the position closes. The cost of holding the position comes from the spread, any commission and overnight financing, which this calculator deliberately leaves out. Our broker cost calculator compares spreads and commissions across 25 brokers, so the trader can see those costs separately.

DFSA and FSRA retail caps by asset class

The caps below come straight from the DFSA (DIFC) and FSRA (ADGM) rulebooks. They apply to retail clients in the DIFC and ADGM free zones, and they bind every DFSA (DIFC)- or FSRA (ADGM)-licensed CFD issuer. No broker regulated by either authority can offer a retail client more. Our team built the calculator to apply them automatically, so the margin shown is the minimum the regulation permits.

A major currency pair, as defined in the rulebooks, is any two of the US dollar, euro, Japanese yen, British pound, Swiss franc, Canadian dollar, Australian dollar and New Zealand dollar. That puts EUR/USD, USD/JPY, GBP/USD and AUD/USD all at 30:1. Any pair involving another currency, like EUR/TRY, is a minor and capped at 20:1. I find this definition trips up traders who assume exotic pairs are just minors.

Each tier is a ceiling on leverage, which makes it a floor on margin. The rulebook's "at least" wording means any broker can require more margin than the minimum. This calculator uses the regulatory maximum, so a broker's own margin schedule can only be equal or more conservative. In my experience, this surprises traders who expect the calculator to match their broker's exact number.

Margin maths

I'll step through the arithmetic: initial margin = notional value x (1 / leverage ratio). For forex, notional is 100,000 units of the base currency per standard lot, converted to the account currency. For gold, notional is 100 ounces per lot at the current spot price. The margin percentage is just the ratio inverted: 30:1 means 3.33% of notional, 20:1 means 5%, down to 2:1 meaning 50% for crypto.

Margin scales linearly with size: 0.10 lots needs one tenth of the margin of 1.00 lot. It also moves with exchange rates when the base currency is not the account currency, which is why the calculator prices notional at current rates rather than assuming a fixed figure. In my opinion, understanding that exchange-rate effect is key to avoiding surprises. The mechanics of margin calls and free equity are covered in our margin guide.

What happens at 50% margin close-out

The same regulatory instrument that caps leverage also mandates close-out protection. When the net equity of a CFD account drops below 50% of the total initial margin required for open positions, the broker must terminate positions as soon as market conditions allow until the account is back above the floor. That 50% is the minimum; a broker may set its close-out trigger higher, so its PDS margin policy is the final word. Combined with negative balance protection, this means a retail account cannot lose more than the funds deposited. I consider this one of the strongest retail safeguards in the DIFC and ADGM rulebooks.

Close-out is calculated across the whole account, not per position. Two positions each using US$3,870.00 of margin share a single US$3,870.00 close-out floor, so a loss on one can trigger the closure of the other. Watching free margin rather than per-trade stop distance is what prevents that surprise.

Professional client leverage, honestly

Brokers may offer higher leverage to clients who qualify as professional under the DFSA (DIFC) and FSRA (ADGM) rulebooks. The criteria are set by the regulator and the firm; contact the broker to learn which classification applies. Qualifying as a professional client removes the retail protections this page describes: the leverage caps, the 50% close-out rule and negative balance protection all stop applying. Higher leverage is a larger loss pipe, not a benefit, unless position sizing discipline replaces the regulatory floor. Our high-leverage broker guide covers who genuinely fits that profile, and I would not treat it as an upgrade without the experience and capital to manage the risk.
