How to use

The Vietnam Car Loan Calculator helps you estimate monthly payments for buying a new or used car. Input the total car price and your planned down payment (percentage or fixed amount). Next, enter the loan term (up to 7-8 years typically) and the bank's annual interest rate. You can also account for mandatory fees like registration tax (lệ phí trước bạ), license plate fees, and insurance. The calculator provides your estimated monthly installment, total interest paid, and a complete amortization schedule, making it easier to budget your dream car.

Monthly payment using flat-rate method (common in VN banks)

Reducing-Balance Monthly Payment

Examples

500M VND car, 30% down, 8.5% flat rate, 5 years

  • Car Price:500,000,000
  • Loan Term:5
  • Annual Interest Rate:8.5
  • Interest Method (1=Flat, 0=Reducing):1
  • Down Payment:30

Result

  • total_cost:1,150,000,000
  • monthly_installment:12,500,000

For a car priced at 1,000,000,000₫ with a 30% down payment, a 5-year loan at 8.5% interest results in a monthly payment of roughly 12,500,000₫. The total cost of the car, including interest and fees, reaches about 1,150,000,000₫.

500M VND car, 30% down, 8.5% reducing balance, 5 years

  • Car Price:500,000,000
  • Loan Term:5
  • Annual Interest Rate:8.5
  • Interest Method (1=Flat, 0=Reducing):0
  • Down Payment:30

Result

  • Total Payment:430,174,800
  • Total Interest Paid:80,174,800
  • Your Monthly Payment:7,169,580

Buying a 500 million₫ car with 30% down and a 5-year reducing-balance loan at 8.5% costs about 7.2 million₫/month. Total interest of 80 million₫ is reasonable — ensure monthly payments stay below 15% of household income to avoid financial stress.

Frequently Asked Questions

What is the difference between flat-rate and reducing-balance car loans in Vietnam?

Flat-rate (lãi suất phẳng) calculates interest on the original loan amount for the entire term, making monthly payments equal but total interest higher. Reducing-balance calculates interest only on the outstanding principal, so interest decreases each month. For the same nominal rate, flat-rate loans cost significantly more — a stated 8.5% flat rate is equivalent to roughly 15–16% reducing balance.

What down payment do Vietnamese banks require for car loans?

Most Vietnamese banks require a minimum down payment of 20–30% of the car's value. Some banks offer 10–15% down for customers with strong credit history. A higher down payment reduces your monthly burden and total interest paid.

What are typical car loan interest rates in Vietnam?

As of 2025, car loan interest rates at major Vietnamese banks range from 7–10% per year for flat-rate loans and 12–18% for reducing-balance loans. Promotional rates as low as 5–6% flat are sometimes offered for new models. Always compare the effective annual rate (EAR) rather than the nominal rate.

What is the typical down payment required for a car loan in Vietnam?

Most banks in Vietnam require a minimum down payment of 20% to 30% of the car's value. Paying a higher down payment can reduce your monthly installments and total interest cost.
