1. Basic concepts of car loan interest rates

The car loan interest rate usually refers to the interest rate of the car loan, that is, the interest rate that the borrower needs to pay when borrowing money from a bank or financial institution to purchase a car. There are two main ways to calculate interest rates:fixed interest rateandfloating rate.
1. Fixed interest rate: The interest rate remains constant and the monthly payments are fixed throughout the life of the loan.
2. Floating interest rate: The interest rate will be adjusted according to market conditions or base interest rates (such as LPR), and the monthly repayment amount may change.

The calculation of car loan interest rates usually involves the following factors:
| factors | Description |
|---|---|
| loan amount | The total purchase price of the car minus the down payment |
| loan term | Usually ranges from 12 months to 60 months |
| Interest rate type | Fixed or floating interest rate |
| Repayment method | Equal principal and interest or equal principal |
1. Equal principal and interest repayment method
The monthly payment is fixed and includes principal and interest. The calculation formula is as follows:
Monthly repayment amount = [Loan principal × monthly interest rate × (1 + monthly interest rate)^number of repayment months] ÷ [(1 + monthly interest rate)^number of repayment months - 1]
2. Equal principal repayment method
The monthly principal repayment is fixed and the interest decreases month by month. The calculation formula is as follows:
Monthly repayment = (loan principal ÷ number of repayment months) + (remaining principal × monthly interest rate)
