The reasons are as follows:

If you repay in full before the repayment date, there will be no interest.

The problem is that if you do not repay in full, the bank will Interest will be calculated on the total amount you owe. Interest will be calculated from the day you swipe the card for consumption and compound interest will be charged after 30 days.

You paid back 1,300 yuan, but the bank calculated and charged interest based on 1,366 yuan. It’s not your 66 yuan that will be used to calculate interest

This situation in your case is called full penalty interest

You can calculate it from the day you swipe the card to make the payment

But luckily you haven't been charged a late payment fee yet. The bank stipulates that the minimum repayment is 10% of the total amount. If you don't repay it, you will be charged a late payment fee in addition to interest, which will be charged at 0.5% of your total amount every day

Fortunately, you paid back 1,300. If not, there would still be late payment fees waiting for you. (5/1000 is 10 times larger than 5/10000)

Stop complaining, many people do. The rules of banks that have been deceived are like this. Banks are all rules set by actuaries. No one can even think of calculating the bank.

Currently, except for the Industrial and Commercial Bank of China, which does not calculate interest in full, all other banks do so. Penalty interest
