Loan EMI Calculator, Amortization Schedule & Mortgage Guide
Calculate your exact monthly payments, total interest costs, and full amortization schedule in seconds.
01. What is an Equated Monthly Installment (EMI)?
An Equated Monthly Installment (EMI) is a fixed monthly payment made to a lender. It pays off both your principal loan amount and accrued interest over a set period.
In standard reducing-balance loans, early monthly payments go mostly toward interest. Later payments pay off more of your principal balance.
The standard mathematical formula for reducing-balance EMI is:
EMI = [P x R x (1+R)^N] / [(1+R)^N - 1]
Where P is your Principal loan amount, R is your monthly interest rate (Annual Rate / 12 / 100), and N is the total number of monthly payments.
- Principal: The total amount borrowed from the lender or bank.
- Interest: The fee charged by the lender for borrowing money over time.
- Tenure: The total loan duration expressed in months or years.
Making small extra payments toward your loan principal early in your loan tenure saves thousands in interest costs.

04. Worked Example: Calculating a $20,000 Auto Loan
Suppose you take a $20,000 car loan at 6% annual interest for 5 years (60 months):
• Monthly Interest Rate (R) = 6% / 12 / 100 = 0.005
• Total Payments (N) = 60 months
• Monthly EMI = $386.66 per month
• Total Amount Paid = $386.66 x 60 = $23,199.36
• Total Interest Paid = $3,199.36 over the life of the loan.
05. Common Mistakes and Misconceptions
Watch out for these common borrowing traps when comparing loan offers:
- Flat Rate vs. Reducing Balance: Flat rate loans charge interest on the full original principal forever. Always choose a reducing balance loan to pay less interest.
- Ignoring Prepayment Penalties: Some banks charge fees if you pay off debt early. Ask your lender if prepayment is fee-free.
- Extending Loan Tenure: Longer terms lower your monthly EMI, but they substantially increase the total interest you pay.

Frequently Asked Questions (FAQ)
What is the difference between flat interest and reducing balance interest?
Flat interest calculates interest on the original loan amount for the entire period. Reducing balance calculates interest only on the remaining unpaid balance. Reducing balance is much cheaper.
Can I download the amortization table to Excel?
Yes. Click the "Export CSV" button to download your full month-by-month repayment breakdown with balance tracking.
Is my financial information private and secure?
Yes. All financial calculations run 100% locally in your browser memory. No figures are stored, tracked, or sent across the internet.
How do I calculate loan EMI and CAGR in Microsoft Excel?
In Excel, calculate monthly loan EMI using the PMT function: =PMT(annual_rate/12, tenure_months, -principal). For example, =PMT(6%/12, 60, -25000). To calculate Compound Annual Growth Rate (CAGR) in Excel, use: =(End_Value/Start_Value)^(1/Years) - 1. You can also export this calculator's complete month-by-month repayment schedule to CSV and open it directly in Excel.
Can this calculator be used for bank car loans and personal financing?
Yes. Select the "Auto Loan" ($35k, 5%, 5y) or "Personal Loan" ($15k, 9.5%, 3y) presets above, or enter custom terms from banks like Al Rajhi, Meezan, HBL, Chase, or SBI to compute exact monthly installments, diminishing balance interest, and full amortization.
