1. Basic composition of bank loan interest rates

Bank loan interest rates usually consist of the following components:
| components | Description |
|---|---|
| base interest rate | The lending benchmark interest rate announced by the central bank is the basis for banks to set interest rates. |
| floating interest rate | The portion of the interest rate that the bank adjusts based on market conditions and the borrower's creditworthiness. |

2. Common loan interest rate calculation methods
Banks usually use the following methods to calculate loan interest rates:
| Calculation method | formula | Applicable scenarios |
|---|---|---|
| Equal principal and interest | 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] | Long-term loans such as home loans and car loans |
| Equal amount of principal | Monthly repayment = (loan principal ÷ number of repayment months) + (remaining principal × monthly interest rate) | Suitable for borrowers with strong early repayment ability |
| Interest calculated daily | Interest = loan principal × daily interest rate × number of borrowing days | Short-term loans, consumer credit |
3. Factors affecting loan interest rates
Banks will consider the following factors when determining loan interest rates:
| factors | influence |
|---|---|
| central bank policy | Adjustments to the base interest rate directly affect bank loan interest rates. |
