# Margin calculator

Forex, futures, indices and crypto. No sign-up, no email.

How much of your balance a position ties up at your leverage.

Instrument

### Position

Size lots

Flat leverage

:1

Current price

Required margin

Enter size, flat leverage and current price.

How it works

`notional = units x contract multiplier x price`

`margin = notional / leverage`

Futures are the exception and do not work this way. They carry a flat margin per contract set by the exchange and your broker, so the calculator asks for that figure directly instead of dividing by a ratio.

A worked example

1. One standard lot of EURUSD at 1.0850.
2. 100,000 units x 1.0850 = $108,500 of notional exposure.
3. At 30:1 leverage, $108,500 / 30 = $3,616.67 of margin.

FAQ

## Worth knowing

### Is margin a cost?

No. It is your own money held aside while the position is open and returned when you close it. What it costs you is flexibility, because margin held on one trade cannot be used for another.

### Why does my broker ask for a different number?

Leverage caps vary by regulator, by instrument and sometimes by account tier, and some brokers raise margin on exotic pairs or over a weekend. Use this to plan, then check the figure your platform shows before you commit.

### What about futures?

Futures margin is set per contract by the exchange rather than derived from leverage, so enter the initial margin your broker publishes and the calculator scales it by your contract count.
