Car Loan Formula (EMI)
EMI (Equated Monthly Installment) for a fixed-rate loan is computed using the annuity formula below.
Formula (mathematical):
EMI = [P × r × (1 + r)n] ÷ [(1 + r)n − 1]
Where:
- P = Loan principal amount
- r = Monthly interest rate (annual rate ÷ 12 ÷ 100)
- n = Total number of monthly installments (years × 12)
Total Payment = EMI × n
Total Interest = Total Payment − P
EMI vs Total Interest
| Metric | What it Shows |
|---|---|
| EMI | Fixed monthly payment you must pay each month |
| Total Interest | Cumulative interest paid over the loan tenure |
This car loan calculator computes your monthly EMI using the standard annuity formula and also provides the total amount you'll pay over the loan tenure and the total interest component. It helps you compare different interest rates and tenures to choose the right repayment plan for your budget.
When to use this calculator
Use this calculator before taking a car loan to estimate affordability, monthly budget impact, and interest costs. It is helpful when comparing loan offers, checking the effect of a slightly lower rate, or testing the impact of a shorter or longer tenure.
How it works (plain explanation)
The calculator converts the annual interest rate to a monthly rate and calculates the EMI so that the borrower pays the same amount every month. Early in the loan, a larger portion of the EMI goes toward interest; later, more goes toward principal. Shorter tenures increase EMI but reduce total interest; longer tenures lower EMI but increase total interest.
Factors that affect car loan cost
Factors include the principal (loan amount), the interest rate, loan tenure, processing fees, and any prepayment or foreclosure charges. Negotiating a lower interest rate or making a larger down payment reduces the loan principal and lowers total interest.
Frequently asked questions
How is EMI calculated? EMI is calculated using the annuity formula shown above which spreads principal and interest across months.
Can I prepay my car loan? Most lenders allow prepayment but check for charges and terms. Prepayment reduces interest and can shorten tenure or lower EMI.
Does loan tenure affect EMI and interest? Yes — longer tenure reduces monthly EMI but increases total interest; shorter tenure raises EMI but reduces total interest paid.
