Amortization Calculator
When you take a loan, most people focus only on the EMI amount. But each EMI you pay actually contains two parts — principal and interest. Understanding how these two components shift over time gives you far better control over your loan.
An Amortization Calculator generates a complete repayment schedule, showing you exactly how much of each EMI reduces your outstanding balance and how much goes toward interest — month by month, for the entire loan tenure.
Why Amortization Matters
Most loans — home loans, car loans, personal loans — follow the reducing balance method. Interest is calculated only on the remaining loan balance each month. Because of this structure:
- In early months, a larger portion of your EMI goes toward interest
- In later months, more of the EMI goes toward reducing the principal
Many borrowers are surprised to see how slowly the loan balance reduces during the initial years. An amortization schedule makes this shift completely visible and helps you plan prepayments at the right time.
Example: ₹5 Lakh at 10% for 5 Years
At the beginning of this loan, a large share of each EMI covers interest on the outstanding ₹5,00,000. By month 30 (midpoint), the split has shifted noticeably — more goes toward principal. By the final months, nearly the entire EMI reduces the balance. The amortization table above shows this shift precisely for any loan you enter.
Tips for Managing Loan Amortization
Make Prepayments in Early Years
Since most of your early EMIs cover interest, a lump-sum prepayment in year 1–3 directly reduces the principal and saves a disproportionately large amount of future interest.
Choose a Shorter Tenure If Possible
A shorter tenure means the principal reduces faster, so less total interest accumulates. Use the year-by-year chart to see how dramatically the interest paid changes with a 5-year vs 10-year tenure.
Use the Schedule to Time Refinancing
If you're considering a balance transfer or refinancing to a lower rate, check the amortization schedule. Refinancing in the early years (when most of the outstanding amount is still principal) gives you the maximum interest saving on the new rate.
Frequently Asked Questions
An amortization schedule is a complete table showing every loan payment broken down into its principal and interest components, along with the remaining balance after each payment. It covers the entire loan tenure from the first EMI to the last, giving you full transparency over your repayment journey.
Because interest is calculated on the outstanding principal balance. In the first month, the full loan amount is outstanding, so interest is at its highest. As you repay principal each month, the balance reduces — meaning interest charges reduce too, and more of each subsequent EMI goes toward repaying principal. This is how the reducing balance method works.
The earlier in the tenure you make a prepayment, the more interest you save — because the prepaid amount would have attracted interest for the remaining months. A prepayment of ₹1 lakh in year 2 of a 20-year loan saves far more total interest than the same prepayment in year 15, when most of the interest has already been paid.
The monthly view shows every individual EMI payment with its exact principal, interest, and balance figures — useful for tracking your loan closely. The yearly view aggregates 12 months into a single row, making it easier to see the big picture for long-tenure loans like 20-year home loans where the monthly table would have 240 rows.
