Quick answer: mortgage amortization

A ₹50,00,000 home at 8.75% over 25 years with 20% down has an EMI of ₹32,885.75. Over the term you pay ₹58,65,723.63 in interest on a ₹40,00,000.00 loan.

Overview of the Mortgage Amortization Calculator

A mortgage amortization schedule shows how a home loan is repaid. For each year (and the first 12 months) it lists the interest, the principal repaid and the balance still owed. Enter the price, down payment, rate and term; optional property tax, insurance, maintenance and extra payments are included.

Because the balance falls slowly in the early years, homeowners who sell or refinance early have repaid less principal than they expect. See how a lump-sum overpayment changes the schedule, or compare the whole thing with the Mortgage Calculator.

How We Calculate

The calculator applies the standard financial formulas step by step.

  1. Convert the annual rate to a monthly rate (÷ 12 ÷ 100) and the term to months.
  2. Work out the amount you actually borrow after down payment, trade-in, fees and any financed charges.
  3. Apply the EMI formula to get the fixed monthly payment.
  4. Build the schedule month by month: interest = balance × monthly rate; principal = payment − interest.
  5. Add up the interest and payments; with extra payments, repeat the schedule to find the interest and time saved.
EMI = P × r × (1 + r)ⁿ ÷ ((1 + r)ⁿ − 1)
r = annual rate ÷ 12 ÷ 100   n = years × 12
total interest = EMI × n − P

Mortgage Amortization Calculator — Frequently Asked Questions

What is a mortgage amortization schedule?

A table of every mortgage payment showing how it is split between interest and principal and the remaining balance.

How much principal do I repay in the first year?

Much less than you might expect — on a long loan, the first-year EMIs are mostly interest.

What if I sell or refinance early?

You will have repaid little principal, so check the balance column before deciding.

Do extra payments change the schedule?

Yes. They cut the balance and the number of payments, saving interest.

Is property tax part of amortization?

No. Property tax, insurance and maintenance are shown separately; they do not reduce your loan balance.

How can I see the monthly detail?

The first 12 months are listed below the summary; the yearly table covers the whole term.

How is the mortgage amortization calculator calculated?

It uses the standard formula: EMI = P × r × (1 + r)ⁿ ÷ ((1 + r)ⁿ − 1) The full method and a worked example are shown on this page.

Is this financial advice?

No. The calculator gives estimates for planning and learning. Real offers vary by lender, product and date, so confirm the details with your bank, lender or a qualified adviser before deciding.

Can I use another currency?

Yes. The maths is identical in any currency; only the currency symbol shown in the results differs.

Is my data stored?

No. Everything is calculated in your browser and nothing you enter is uploaded or saved.
