Quick answer: Car loan EMI = [P × r × (1+r)n] ÷ [(1+r)n − 1], where P is the financed amount (price minus down payment), r is the monthly interest rate, and n is the number of months. Enter your vehicle price, down payment, annual interest rate and loan term below for the exact monthly payment.

Key facts
- EMI = P × r × (1+r)n ÷ ((1+r)n − 1) — the standard reducing-balance formula.
- Each payment first covers that month's interest; the rest reduces the principal.
- A bigger down payment cuts both the EMI and the total interest you pay.
- Shorter terms mean higher EMIs but far less total interest.
This free car loan EMI calculator computes your exact monthly payment from vehicle price, down payment, annual interest rate and loan term, using the same reducing-balance formula lenders worldwide apply to auto loans. Adjust any input and see results instantly.
Enter your numbers and instantly see the monthly EMI, financed amount, total payable and total interest. No sign-up, works on mobile and desktop.
How to use
- Enter the vehicle price (e.g. 30,000).
- Set the down payment % you will pay upfront.
- Enter the annual interest rate % from your lender's offer.
- Choose the loan term in years and read your EMI.
How car loan EMI is calculated
| Term | Meaning |
|---|---|
| P (principal) | Financed amount = vehicle price − down payment. |
| r (monthly rate) | Annual rate ÷ 12 ÷ 100. For 8% annual, r = 0.006667. |
| n | Number of monthly payments = years × 12. |
Lenders use the reducing-balance method: early payments are mostly interest, later payments mostly principal.
Worked examples
30,000 car, 5-year loan
Price 30,000, 20% down → P = 24,000. Rate 8% annual → r = 0.006667, n = 60.
EMI = 486.63 per month. Total payable 29,198, of which 5,198 is interest.
18,000 car, 4-year loan
Price 18,000, 10% down → P = 16,200. Rate 6.5% annual, n = 48.
EMI = 384.18 per month. Total payable 18,441, of which 2,241 is interest.
Typical auto-loan terms
| Item | Usual range |
|---|---|
| Down payment | 10–20% of vehicle price |
| Annual interest rate | Varies by lender and credit score |
| Loan term | 3–7 years |
| Extra fees | Origination or processing fees may apply |
Frequently asked questions
How is car loan EMI calculated?
With the reducing-balance formula EMI = P × r × (1+r)n ÷ ((1+r)n − 1). P is price minus down payment, r is the annual rate ÷ 12 ÷ 100, and n is the number of months.
Does a bigger down payment really help?
Yes twice over: it shrinks the financed principal (lower EMI) and it shrinks the total interest because interest is charged on a smaller balance.
Is a longer loan term cheaper?
No — it lowers the monthly EMI but increases total interest substantially. Compare the "total payable" figure across terms.
What is the difference between flat rate and reducing balance?
Reducing-balance interest is charged on the outstanding principal each month, so it falls over time. Flat-rate interest is charged on the original principal for the whole term — always more expensive for the same quoted rate.
Should I include fees in the comparison?
Yes. Add origination and processing fees to the total payable when comparing lender offers — the lowest rate is not always the cheapest loan.

Key takeaways
- Car EMI uses the reducing-balance formula on (price − down payment).
- Bigger down payment = lower EMI and less total interest.
- Shorter term = higher EMI but far less interest paid.
- Always compare total payable, including fees, not just the monthly figure.
