What is Margin?
Above, we said “leverage” and “margin” are two terms that are often used interchangeably. This is true, but we should qualify it by explaining that the two do have slightly different meanings.
If you’re searching for a margin meaning, this is the amount of money you’ll need to open your position, while leverage is the multiple of exposure. If you’d like to know how to calculate margin, work out the size of your intended position and then divide this by the higher number.
Lots of brokers will have a margin calculator on their page, but this is usually easy enough to work out in your head. In the example we used above, our hypothetical broker wanted to trade £25,000 with leverage of 25:1. The margin formula they’d need to use would therefore be:
£25,000 / 25 = £1,000
Equally, if the leverage was 5:1, they’d have to put down £5,000 to manage the same size position. The formula in this instance would be:
£25,000 / 5 = £5,000
Essentially, this means you work out the margin in the following way:
Size of position / the higher figure in the ratio = the margin.
When buying on margin, the size of your deposit will depend on the leverage offered and the trading terms supplied by the broker. This payment is known as the “initial margin”. Margin requirements can differ widely depending on factors like the asset type, market, and risk involved.
