The average capital method is to divide the loan principal evenly according to the total repayment months (average capital), and add the monthly interest of the remaining principal in the previous period to form the monthly repayment amount. According to the above definition, the monthly principal of Xiao Li's loan is: 150000/240=625 yuan; The payment base is: 50000/625=80 installments; Residual principal:150000-50000 =100000 yuan; The interest portion of 1.300 yuan's principal and interest to be repaid this month is: 1.300-625 = 675 yuan; The current monthly interest rate is: 675/ 100000 = 6.75‰(6.75‰).
How to calculate the monthly interest rate of bank loans?
The calculation method of 1. monthly interest is the monthly interest rate of loan amount, and the calculation method of annual interest is the annual interest rate of loan amount.
2. The annual interest rate and the monthly interest rate are mainly different. The monthly interest rate can be converted into annual interest rate, and the monthly interest rate is 12= annual interest rate. If the loan term is in years and the repayment method is equal principal and interest or equal capital, the calculation method of interest will be different. Ordinary car loans and mortgage loans generally adopt equal principal and interest or average capital's repayment method. I suggest you use the loan calculator directly. It will be more complicated to use the formula. Monthly interest rate = monthly interest rate × time× principal; Annual interest rate = monthly interest rate × 12 (month )× time× principal. Interest rate conversion formula: daily interest rate = monthly interest rate ÷30 (days) = annual interest rate ÷360 (days). Examples are as follows:
1) monthly interest, for example, if you lend money to others, the monthly interest is 1 (1%), then you take 1 × 1, and one month is 1000 yuan. If the annual interest rate is 4%, you can get 4000 yuan a year, and 4000 yuan a month/12 = 333.3 yuan.
2) The annual interest rate is 12 months. For example, if the annual interest rate of 6.5% is converted into a monthly interest rate, the monthly interest rate is 6.5%/ 12 ≈ 0.54%. If the monthly interest rate is converted into annual interest rate, it is called annualized rate. There are two situations: 1) compound interest (interest rolling), annual interest rate.
1. Interest rates generally have three forms: annual interest rate, monthly interest rate and daily interest rate. The annual interest rate is expressed as a percentage of the principal, which China calls "points"; The monthly interest is expressed as a few thousandths of the principal, which China calls "profit"; The daily interest rate is expressed as a few ten thousandths of the principal, which is called "milli" in China.
2. The interest is calculated as follows:
1) Regular interest calculation: for the account whose interest is calculated by deposit and loan balance table or subsidiary ledger, the number of days is calculated from the deposit and loan date to the day before the withdrawal and return date. The calculation formula is interest = accumulated interest product × daily interest rate.
2) Interest calculation on a case-by-case basis: the annual interest is calculated for the whole year, and the monthly interest is calculated for the whole month. There are whole years (months) and odd days, which can be converted into whole days. All years: interest = principal × time× annual interest rate or monthly interest rate. All converted into days: interest = principal × time× daily interest rate.
I would like to ask how to calculate the monthly interest rate and annual interest rate when lending.
The loan interest rate standard of China People's Bank is calculated by "annual interest rate". Numbers are generally expressed as percentages, and "5.3 1%/ year" means "5.3 1%/ year".
The monthly interest rate is calculated by dividing the annual interest rate by 12 natural months, that is, "monthly interest rate = annual interest rate/12 months". Numbers are generally expressed in thousandths.
Suppose the loan is 654.38+0.5 million, and the monthly interest rate is 0.6%, then the annual interest rate is 7.2%.
Monthly interest rate and annual interest rate are two ways to express interest rate: if the interest rate of a product is 6%, it means annual interest rate, that is, the monthly interest rate is 5 ‰. Simply put, the annual interest rate is a percentage, and the monthly interest rate is one thousandth.
For example, the monthly interest rate of this new product is five thousandths, and it is deposited in 654.38+ten thousand yuan, and the monthly interest rate is 500 yuan. Pay 106000 yuan at maturity after one year, expressed by 6% annual interest rate, that is, pay 106000 yuan at maturity after one year. The amount is the same, but the expression is different.

Calculation method:
(1) The interest rate conversion formula for RMB business is (note: common for deposits and loans):
1. daily interest rate (0/000)= annual interest rate (%)÷360= monthly interest rate (‰)÷30.
2. Monthly interest rate (‰) = annual interest rate (%)÷ 12
How to calculate annual interest and monthly interest;
Calculation method: interest income = principal × annual interest rate × time.
For example, if you manage your money for 3 months, the annual interest rate will be 10000 yuan.
Then, interest income = principal × annual interest rate × time = 10000 yuan × 18%×3 months/12=450 yuan.
For example, if you manage your money for 3 months, the annual interest rate will be 1 10,000 yuan.
Interest income = principal x annual interest rate x time = 10000 yuan x18% x 3 months/12=450 yuan.
