Calculating real yield on bank loan
Please explain the following excerpt I came across. I'm looking for the calculation.
... When you compute the real yield on a 6.75% loan offer, you will find it is actually a 26% loan. (Because you're paying interest on 100% of the loan amount, but have only received 80% of the money from the bank, the rest is your own compensating balance being "loaned" back to you). Using the same formula, a 10% compensating balance brings the bank's effective loan rate "down to 15%. Anyway your cut it, that's a far cry from 6.75%.
The questions is how did they calculate 26%?

In case interest is 6.75%pa and loan period is:
2yrs: Actual interest p.a. = (100%-80%)/2+6.75 = 16.75%
3yrs: Actual interest p.a. = (100%-80%)/3+6.75 = 13.42%
4yrs: Actual interest p.a. = (100%-80%)/4+6.75 = 11.75%
and so on.
