Margin Utilization (see “5” in the below image) is the percentage of margin collateral that you are utilizing for margin products trading. If the margin utilization exceeds 100% there is a risk that your margin positions will be stopped out.
Margin Utilization is calculated as = (100 * Used for margin) / (Account value + Other collateral – Not available as margin collateral).
All the data can be found in the Account Summary (see 1-4 in the below image)
In this example the client has EUR 13.861,63 – EUR 888,42 = EUR 12.973,21 as available margin in total. Of these EUR 12.973,21 currently 3.049,51 is used for margin requirements. 3.049,51/12.973,21 = 24% margin utilization.
