Home Loan Amortization Calculator

Interest is charged on the outstanding balance, which is largest at the start of the loan. As you pay down principal, the interest portion of each EMI shrinks and the principal portion grows, even though the EMI itself stays constant.

This calculator shows one year at a time — enter different values in "year to inspect" to compare any two years, such as year 1 vs. year 15.

Yes significantly — see the Home Loan Prepayment Calculator to see how extra payments shorten the schedule and shift more of each payment to principal sooner.

For a ₹30,00,000 loan at 8.5% over 20 years, year 1's payments are about 80.9% interest (₹2,52,709.49 of the ₹3,12,416.37 paid that year) and only about 19.1% principal (₹59,706.88). By year 20 that flips almost completely: interest is down to about 4.5% of that year's payments (₹13,921.04), with roughly 95.5% going to principal (₹2,98,495.32) — even though the EMI itself never changes.

Yes, for the same principal and rate — though the EMI itself is higher. For a ₹30,00,000 loan at 8.5%, a 20-year tenure carries an EMI of ₹26,034.70 and total interest of ₹32,48,327.28 over the life of the loan. A 10-year tenure raises the EMI to ₹37,195.71 but cuts total interest to ₹14,63,484.80 — over ₹17,84,000 less — for paying off the exact same principal.

For the same ₹30,00,000 loan and 20-year tenure, raising the rate from 8.5% to 10.5% increases the EMI from ₹26,034.70 to ₹29,951.40 (about 15% higher) but increases total interest paid over the full tenure from ₹32,48,327.28 to ₹41,88,335.19 (about 29% higher) — total interest grows faster than the EMI because the higher rate compounds over the same repayment period.

The calculator rejects it rather than showing a zeroed or misleading row. For example, a 24-month (2-year) loan only has a year 1 and year 2 — entering year 5 fails validation because there's no such year in that loan's schedule. Keep "year to inspect" at or below the tenure in months divided by 12, rounded up.

No — it models a single fixed interest rate applied consistently across the entire tenure, based only on the loan amount, rate, and tenure you enter. It does not add processing fees, legal or valuation charges, or prepayment penalties, and it does not account for a floating rate that resets partway through the loan. If your actual rate changes over time, run each rate period as a separate calculation.
