Calculating CFD margins

In order to open a CFD (contract for difference) position on your account, you will need to deposit an amount of money known as margin.

The margin reflects a percentage of the full value of the position, and is referred to as 'position margin' on our platform. The position margin will be calculated using the applicable margin rates, as shown in the product library area on the platform. Read more about our CFD margin rates.

CFD margin explained

For shares, different margin rates may apply depending on the size of your position, or the tier your position (or a portion of your position) in that instrument falls within. The portion of the position that falls within each tier is subject to the margin rate applicable for that tier.

In order to calculate the position margin, the level 1 mid-price (shown on the platform) is used.

Position margin example

Company ABC (GBP) margin rates

Tier	Position size (units)	Margin rate
1	0-1,000	20%
2	>1,000-3,000	25%
3	>3,000-5,000	30%
4	>5,000-10,000	40%
5	>10,000	50%

Unit in Tier 1 x Tier 1 Margin rate

Unit in Tier 2 x Tier 2 Margin rate

The sum of: Unit in Tier 3 x Tier 3 Margin rate x level 1 mid-price

Unit in Tier 4 x Tier 4 Margin rate

Unit in Tier 5 x Tier 5 Margin rate

Based on the margin rates in the table below for Company XYZ ($AU), if a position of 6500 units used the level 1 mid-price of $2.75, the margin would be $5,225.

Your position margin requirement is calculated as follows:

Tier	Position size	Margin rate	Calculation
1	1,000	20%	1,000 x 2.75 x 20% = $550
2	2,000	25%	2,000 x 2.75 x 25% = $1,375
3	2,000	30%	2,000 x 2.75 x 30% = $1,650
4	1,500	35%	1,500 x 2.75 x 40% = $1,650
5	0	50%	0
Total	6,500		Total = $3,437.50

The notional value of your total position is $17,875.00 ($6,500 x $2.75).

CFD margin requirement

As you can see, margin trading allows you to open a position by depositing a percentage of the full value of the position. This means that your losses will be amplified and you could lose more than your initial deposit. Profits and losses are relative to the full value of your position.

Trading using margin is not necessarily for everyone, so you should ensure that you understand the risks of CFDs, and if necessary, seek independent professional advice before placing any trades.
