Binance usdt Future Fees questions

Hello, i only recently began making an attempt out the usd-t future

it was listed on binance that there's 2 charges for future transaction, which is transaction charge (maker/taker) and funding charge

i then tried out to open a brief position on SOL while utilizing isolated margin, risking 10 usdt per trade as a sl

i open a place at 33.59 /sol and purchased 12 SOL, and the liquidation worth was 34.1577, i need to have a 1:1 RR so i caclulate the worth distinction which is a .5677 worth difference

after which if i put my tp at 33.59 - .5677 which is at 33.0223, i only achieve around $7

so principally im risking $10 to get $7, am i missing something? i exploit 50x leverage if that have any impression on the charges?

my charge calc
$400 * .0004 (maker payment) = $.16
no funding payment.

the charge must be $.16 and not $3?

TL:DR

if i need to commerce with 1:1 RR ratio utilizing $10 capital, using binance future, i lose $3 to fee every commerce?
