Let’s take BUSD for example.

0.047681% Borrow DAILY Interest Rate.
That means if you borrow 10000$ and hold your position for a day, you will pay 0.047681%.
10000*0.047681% = 4.7681$
No big deal? 5$ is nothing if you get to borrow 10000$ right?
So you decided to take a long long position for a year or two or more to get through the bear market.
How does 4.7681$ every day for 365 days sound?
1740.35 $
So the annual interest rate if you forget about compounding is 17.40%.
Since compounding is a thing and it doesn’t stop existing if you forget it.
Compounding Daily interest rate for 365 days = Actual annual interest rate
Actual annual interest rate = (1+(0.047681/100))365 – 1
= 1.19004863 – 1
= 0.19004863
The actual annual interest rate comes out to 19%.

If you think your trading strategies yield you more than 19% + inflation rate, you do not need to look at these fees.
If you are struggling to break even year on year, you need to rethink your margin positions.
