Calculate your exact monthly auto loan payment (EMI), total interest cost, complete amortization schedule, and compare multiple financing scenarios in real-time.
Pro Tip
Consider both dealership financing and direct lending from banks or credit unions. Getting pre-approved for a loan from a direct lender before visiting the dealership can give you more negotiating power and potentially secure a better interest rate[citation:1].

Purchasing a vehicle is one of the most significant financial decisions after buying a home. Our advanced car purchase calculator helps you understand the complete financial picture, from your monthly EMI to the total interest paid over the loan's life. Unlike basic calculators, this tool provides a detailed amortization schedule showing how each payment is split between principal and interest[citation:1][citation:4].
The Equated Monthly Installment (EMI) for your car loan is calculated using the standard annuity formula, which considers the principal amount (vehicle price minus down payment), annual interest rate, and loan tenure in months[citation:4][citation:8]. The formula ensures that each payment includes both interest and principal repayment, with the interest portion being higher in the initial payments and gradually decreasing over time as shown in the amortization schedule.
You typically have two main financing options: dealership financing (convenient but may have higher rates) and direct lending through banks or credit unions (often lower rates but requires separate approval). Manufacturer-sponsored financing sometimes offers special promotions like 0% or 1.9% APR for qualified buyers[citation:1]. Getting pre-approved through direct lending before visiting dealerships gives you stronger negotiating power.
Manufacturers often provide a choice between cash rebates and low-interest financing. Use the comparison feature in this calculator to determine which option saves you more money based on your loan amount and term. Generally, cash rebates are better for shorter loan terms or when making a large down payment, while low-interest financing benefits longer loans[citation:1].
Important Consideration
New cars experience immediate depreciation (often 10-20% in the first year). Consider certified pre-owned vehicles that are 2-3 years old for better value, as the steepest depreciation has already occurred[citation:1].

The EMI is calculated using the standard loan amortization formula: EMI = [P × r × (1+r)^n] / [(1+r)^n-1], where P is the principal loan amount, r is the monthly interest rate (annual rate divided by 12), and n is the number of monthly installments[citation:4][citation:8]. This formula ensures each payment covers both interest and principal, with the interest portion decreasing over time as shown in the amortization schedule.
Shorter terms (36-48 months) mean higher monthly payments but significantly less total interest paid. Longer terms (72-84 months) lower monthly payments but increase total interest costs substantially. Consider a middle ground (60 months) for balance. Remember, cars depreciate quickly, so you don't want to be paying for a vehicle longer than its useful life or be "upside down" on your loan (owing more than the car's value)[citation:1].
Financial experts typically recommend at least 20% down payment for new cars and 10% for used cars. A larger down payment reduces your loan amount, may secure a better interest rate, and helps avoid being "upside down" on your loan. Some lenders require minimum down payments based on credit score. Use the calculator to see how different down payments affect your monthly EMI and total interest.
It depends on your loan amount and term. Cash rebates (immediate price reduction) are generally better for shorter loans or when making a large down payment. Low-interest financing (often 0%, 0.9%, or 1.9%) saves more on longer loans. Use the comparison feature in this calculator to evaluate both options with your specific numbers. Note that some rebates may be taxable in certain states[citation:1].
Beyond the vehicle price, budget for: Sales tax (varies by state, 0-10%), registration and title fees ($100-$500), documentation fees ($100-$400), destination charges ($900-$1,500 for new cars), and insurance (typically $1,000-$2,000 annually for full coverage). Some dealers may also charge advertising fees. These can often be rolled into the financing but increase your loan amount and total interest[citation:1].
Credit score is the primary factor determining your interest rate. Excellent credit (720+): 3-5% APR. Good credit (680-719): 5-7% APR. Fair credit (620-679): 7-12% APR. Poor credit (below 620): 12-20% APR or may require a co-signer. A difference of just 2% on a ₹12 lakh, 5-year loan can save over ₹75,000 in total interest. Check your credit score before applying and correct any errors.
Financially, used cars (2-3 years old) typically offer better value because the steepest depreciation (often 20-30% in first year) has already occurred. Certified Pre-Owned (CPO) programs offer warranties and inspections. New cars have the latest features, full warranty, and sometimes better financing deals. Calculate the total 5-year cost of ownership (purchase price, interest, depreciation, insurance, maintenance) for both options before deciding[citation:1].
