1. Basic concepts of financial loan for car purchase

Financial loan car purchase means that consumers purchase cars through loans from banks, auto finance companies and other financial institutions, and repay the loan principal and interest according to the agreed interest rate and term. This method can alleviate the financial pressure of paying the full amount at once, but it requires paying a certain interest cost.
2. Calculation method of financial interest
The calculation of financial interest usually involves the following key factors: loan amount, loan term, interest rate type (fixed interest rate or floating interest rate), and repayment method (equal principal and interest or equal principal). The following are common calculation methods:
| calculation factors | Description | Example |
|---|---|---|
| loan amount | The total purchase price of the car minus the down payment amount | The car price is 200,000, the down payment is 60,000, and the loan is 140,000. |
| loan term | Usually 12-60 months | 36 months (3 years) |
| Interest rate type | Fixed or floating interest rate | Fixed interest rate 5% |
| Repayment method | Equal principal and interest or equal principal | Equal principal and interest |
3. The difference between equal principal and interest and equal principal
Equal installments of principal and interest and equal installments of principal are two common repayment methods. They differ in interest calculation and monthly payment amounts:
| Repayment method | Features | Monthly payment amount | total interest |
|---|---|---|---|
| Equal principal and interest | The monthly repayment amount is fixed, including principal and interest | Fixed | higher |
| Equal amount of principal | The monthly principal repayment is fixed, and the interest decreases month by month. | Decreasing | lower |

| Repayment method | Monthly payment amount (yuan) | Total interest (yuan) | Total repayment amount (yuan) |
