Struggling to understand leverage and margin

so ive reading up on leverage and margin and im still quite confused about how it works. i want to open a $400-$500 account to make .1 trades (minis). in order to control a .1 of a lot with $400, i would be on 25:1 leverage, correct? now lets say i lose $400. would i then receive a margin call?

also using a different scenario, lets say again i want to control .1 of a lot with $400. can i go 50:1 leverage to make $200 control one .1 sized lot? would that mean that i can lose $200 before i receive a margin call?

im thoroughly confused about margin and leverage. ive gone through pip school and read a couple of posts on it, but i still dont fully understand it. ive been reading about trading a lot and ive been demotrading, but i still dont fully understand margin+leverage. anyone care to help?

no biters?

Your making it harder than it has to be. Look up some of clints posts as he can explain this better than I can ever dream of. Sound like you are getting the concept
