Now loans have become more and more popular, because it allows people to spend in advance and repay in installments later, greatly reducing the economic burden. In this process, only some loan costs need to be properly paid, and the amount of this loan cost needs to be calculated by the loan interest rate. So, what is the formula for calculating the loan interest rate? Let's take a look together.

I. Calculation formula of loan interest rate

1, daily interest rate = monthly interest rate /30 days = annual interest rate /360 days;

2. Monthly interest rate = daily interest rate for 30 days = annual interest rate/12 months;

3. Annual interest rate = monthly interest rate 12 months = daily interest rate of 360 days;

4. Interest = loan principal loan interest rate loan term;

5. Under the average capital method, interest = the loan interest rate of the remaining principal to be repaid;

6. Under the equal principal and interest method,

Monthly interest = the monthly interest rate of the remaining loan principal.

Monthly repayment amount = [loan principal × monthly interest rate ×( 1 interest rate) repayment months ]≤[( 1 interest rate) repayment months-1],

If the repayment period is 6 and the monthly interest rate is 1%, then (11%) 6 =1.01.0165438.

Second, for example.

Assuming that the loan principal is 6000 yuan, the loan term is 6 months, and the monthly interest rate is 1%, then:

1, average capital model

Monthly repayment amount =6000/6= 1000 yuan,

The first month loan interest =6000 1%=60 yuan;

The loan interest of the next month = (6000-1000)1%= 50 yuan;

Third month interest =(6000-2000) 1%=40 yuan;

The fourth month interest =(6000-3000) 1%=30 yuan;

The fifth month interest =(6000-4000) 1%=20 yuan;

Interest of the 6th month = (6000-5000)1%=10 yuan.

2. Under the equal principal and interest method

Monthly repayment amount = (60001%1.06)/(1.06-1) =1035.29 yuan,

The first month loan interest =6000 1%=60 yuan, and the remaining loan principal = 6000-(1035.29-60) = 5024.71yuan;

The loan interest of the next month is 5024.711%= 50.25 yuan, and the remaining loan principal is 5024.71-(1035.29-50.25) = 4039.67 yuan;

Conversely, the interest of the sixth month = 10.25 yuan.

The above is about the "loan interest rate calculation formula", I hope it can help you.

How to calculate the monthly loan interest rate

The monthly interest rate of a loan can be converted into annual interest rate and daily interest rate. Loan interest rate conversion formula: monthly interest rate = annual interest rate ÷12; Monthly interest rate = daily interest rate 30; Users must distinguish between annual interest rate and monthly interest rate when lending. After all, different loan interest rates charge different interest rates.

When handling loans in banks, it is generally the annual interest rate, but different loan types get different loan interest rates. When making a loan, the borrower can consult different banks, so that he can know which bank has a low loan interest rate and understand the loan conditions, and finally choose the bank with the best cost performance.

It is best to measure your repayment ability in advance when applying for a loan. If your personal income is relatively high at ordinary times, you can rest assured that you can borrow money at this time. If the personal income is not very high, you can reduce the loan amount or give up the loan at this time to avoid late repayment.

Users can consult the bank in advance when applying for a loan, because different loan types need different conditions. Common loan types include mortgage loans, commercial loans, credit loans and so on. The amount and interest rate of these loans will be different when they are handled.

What are the formulas for calculating the interest rate of bank loans?

Interest rate = interest/principal/time × 100%

For example: deposit 100 yuan,

The bank promised to pay an annual interest rate of 4.2%

Then the bank will pay 4.2 yuan interest in the second year.

The calculation formula is 100×4.2%=4.2 yuan.

The formula is: interest rate = interest ÷ principal ÷ time × 100%.

Interest = principal × interest rate× time

= 100×4.2%=4.2 yuan.

The final withdrawal 104.2= 104.2 yuan.

Matters needing attention

1. When applying for a loan, the borrower makes a correct judgment on his repayment ability. Design a repayment plan according to your income level, leaving room for it and not affecting your normal life.

2. Choose the appropriate repayment method. There are two repayment methods: equal repayment and equal principal repayment. Once the repayment method is agreed in the contract, it shall not be changed during the whole loan period.

3. Repay on time every month to avoid penalty interest. From the month following the initiation of the loan, the lending time of the next month is usually the repayment date. Don't default on the penalty interest because of your negligence, so that the bank can't approve the loan application again.

4. Take care of your contract and receipt, read the terms of the contract carefully, and know your rights and obligations.

How to calculate the monthly interest rate of loans?

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‰).
