The fairest way for banks to use ordinary commercial loans is: how much principal you still owe the bank, how much interest will be generated on the next repayment date, plus part of the principal, which is the repayment amount of that month. Private loans are part of your money in the first month, and he is still calculating the interest on this part until the last day of your loan term, which is why you will suffer. If it is really calculated in this way, it is not usury, but it deliberately hides the disadvantages of your ignorance of the calculation formula. Usury shall not be calculated on an annual basis. For example, if you roll once a month, the interest rate will scare you to death. If you press 5% roll 12 times, it will be (1+5%)12 =1.7958, which is close to 80% a year.
If you can get a 6% loan from the bank, it won't be more expensive, at least it's safe and secure.
I put 3000 yuan into the fund and bought a hybrid fund. It only took 9 days (7 working days) to earn 15%. Now the stock market turnover is so large that fund investment has made a lot of money in a short time. Do you think people will lend you money to earn 4% interest?
Just to reassure you to borrow it for a few more years. The longer the time, the more interest you will get than the bank. Although I earn less than buying funds this year, it is still stable and cost-effective to collect interest next year. After all, the stock market is risky, and this loan is not risky. If you don't pay back the money, they have grey means to approach you to pay back the money.
