I don't know how to calculate the loan amount, repayment method and floating interest rate.

Second, I would like to ask experts, are those who have never paid interest after bank loans illegal?

If the interest has not been paid back after the bank loan, and the interest amount is large, the bank will chase it. Will be blacklisted by the bank.

3. What is the bank loan plus interest for1015? Ask the gods for answers.

The bank won't

Suppose the interest plus principal * * * is 10000( 1 yuan)

4. The Bank of loans overdue didn't rush it. After 15, it asked for the principal. Is it necessary to pay interest?

According to the provisions of Article 232 of the Civil Procedure Law, if the person subjected to execution fails to perform the obligation to pay money within the period specified in the judgment, ruling or other legal documents, he shall pay double the interest on the debt during the delayed performance. If the person subjected to execution fails to perform other obligations within the period specified in the judgment, ruling or other legal documents, he shall pay the delay in performance. The purpose of this clause is to enable the winning party to obtain the litigation results in time, and to urge the losing party to fulfill its obligations in time, regardless of whether the parties agree on interest or not.

Therefore, although the debtor did not agree on the interest when borrowing from the creditor, the judgment can still require double payment of the debt interest during the delayed performance.
