Margin level increase with leverage - Why?

What could be the reasons that my margin levels increase when I increase my leverage?
With 200:1 leverage my margin level is 316%
and with 500:1 my margin level is 717%

Any reasons for this?

All answers and comments are valued high ! thank you!

(Equity/Used Margin) X 100= % Margin Level

If the broker is giving you more leverage your margin requirement will be less with 1:500 than 1:200

For example to open one lot of EURUSD

100,000 (1lot) * 1.01937 (Exchange rate)/ 500( leverage)=$203.87
100,000 (1lot) * 1.01937 (Exchange rate)/ 200( leverage)=$509.68

Your Used Margin will be less if you open the lot with 1:500 therefore when you divide the margin by your equity the % Margin will be higher.

However, keep in mind with high leverage you are at risk to be overexposed if you don't control your volume. Which is one of the main reasons why 89% of retail traders get busted.
