So there's a personal loan, 600'000 THB with a bank.
According to some quick research, the max allowed interest rate for such a loan is 15%.
However, 8 payments have been made into repaying said loan, 8x 16'000 = 128'000 and the loan "balance" has only come down to 564'000.
Apparently the loan is for 71 instalments, 16k each - so that is a total of 1.136 million THB.
How is that 15%? That is more like 100% extra interest ?
Can someone please ELI5 that?
