The algorithm of interest-free loan is relatively simple. The down payment is usually 30% of the car price. The car price MINUS the down payment is the loan amount, and the loan amount divided by the number of loan months is your monthly repayment amount. For example, if the car price is 654.38+10,000 yuan, you pay 30,000 yuan as down payment, 70,000 yuan as loan for two years, and monthly repayment = 70,000 /24 = 29 17 yuan. Of course, there will be a handling fee for installment loans, which is generally about 3%~4% of the loan amount, and each brand should be different. When making a car purchase budget, it should be down payment+handling fee+insurance+purchase tax+licensing fee, and you can go on the road after you finish the car.
