Mortgage Calculator – Plan Your Home Loan Repayments Before You Commit
Buying a home is the largest financial commitment most people will ever make. Unlike almost any other purchase, a mortgage runs for decades — and the decisions you make at the start determine what you pay not just next month, but for the next 20 or 30 years. Getting those numbers right before you sign matters enormously.
This free mortgage calculator gives you an accurate picture of your monthly repayments, the total interest you'll pay over the life of the loan, and the true all-in cost of your home purchase — including property tax and insurance — in a matter of seconds. No appointments. No waiting for a bank call-back. Just clear, accurate numbers on demand.
What Is a Mortgage Calculator?
A mortgage calculator is a financial tool that estimates your monthly home loan repayment based on the loan amount, interest rate, and loan term. It breaks down exactly how much of each payment goes towards repaying the principal (the amount you borrowed) and how much goes towards interest charged by the lender.
Beyond the basic monthly payment, this home loan calculator also lets you factor in property tax and homeowners insurance — the real costs that many buyers overlook when budgeting for their monthly housing expenses. Including these gives you a far more accurate picture of what homeownership will actually cost month to month.
A mortgage payment calculator is essential for anyone who is:
Comparing loan offers from different lenders to find the best deal
Deciding how large a home loan they can comfortably afford on their income
Evaluating whether to choose a shorter or longer mortgage repayment term
Understanding the total cost of a home purchase including all financing charges
Planning their monthly budget around a new home loan EMI commitment
How to Use the Mortgage Calculator
This tool is built to be simple and comprehensive at the same time. Here's what each input means:
The amount you plan to borrow — typically the property price minus your down payment. For example, if the property costs ₹80 lakh and you're putting down ₹16 lakh (20%), your loan amount is ₹64 lakh.
The annual interest rate on your home loan. In India, home loan rates range from approximately 8.5% to 11%. Always enter the specific rate you've been quoted for the most accurate results.
Standard home loan tenures in India range from 5 to 30 years. A shorter term means higher monthly EMIs but less total interest. A longer term reduces monthly burden but significantly increases total repayment.
Property tax levied by municipal authorities varies by city and property type. Including this gives you the real monthly housing cost, not just the loan EMI.
Home insurance protects your property against fire, natural disasters, and theft. Many lenders require at least a fire insurance policy as a loan condition. Including it makes your estimate complete.
Once you click Calculate, the tool immediately shows your monthly payment broken down into principal and interest, optional tax and insurance, total amount paid over the life of the loan, and total interest paid — all in one clean summary.
Principal and Interest — What You're Actually Paying For
Every mortgage repayment is made up of two components: principal and interest. Understanding how these work together is fundamental to understanding your loan.
Principal
The original loan amount you borrowed. Every rupee of principal you repay reduces your outstanding debt and builds your equity in the property. This is money working directly in your favour.
Interest
What the lender charges for lending you the money. In early years, the majority of each payment goes towards interest. As the loan matures, this shifts — more goes towards principal repayment.
Why this matters: This structure — called amortisation — means the first few years of a home loan are the most expensive in terms of interest-to-principal ratio. Making even small additional payments early in the loan can have a disproportionately large impact on total interest paid.
A home loan EMI calculator that breaks down principal vs interest helps you see exactly this — and makes the case for either choosing a shorter tenure or making occasional lump sum prepayments where possible.
How the Loan Term Affects Your Total Cost
The loan tenure you choose has a bigger impact on the total cost of your home than most buyers realise. Here is a real example that makes the trade-off concrete:
| Scenario | Monthly EMI | Total Interest | Verdict |
|---|---|---|---|
| ₹60L @ 9% — 15 Years | ~₹60,800/mo | ~₹49 lakh | Best value ✓ |
| ₹60L @ 9% — 25 Years | ~₹50,400/mo | ~₹91 lakh | ₹42L extra cost ✗ |
The right choice depends on your income, cash flow, and long-term plans. Use the mortgage payment calculator above to run multiple tenure scenarios and find the balance between monthly comfort and total cost efficiency. For a broader view, our investment calculator can help you model what the difference in monthly payments could grow to if invested elsewhere.
Fixed Rate vs Floating Rate — Which Should You Choose?
Most home loan borrowers in India face a fundamental choice between a fixed interest rate and a floating (variable) interest rate. Both have distinct advantages depending on your situation.
Certainty & Stability
Locks in your interest rate for an agreed period. Your EMI doesn't change regardless of market interest rate movements. Ideal for those who value predictable monthly outgoings.
Market-Linked Flexibility
Linked to the RBI repo rate via MCLR or RLLR. When repo rate falls, your EMI decreases. Most home loans in India today are floating rate — borrowers benefit directly from RBI rate cuts.
The mortgage interest rate calculator in this tool works for both rate types. Many borrowers also use it to stress-test their budget — entering a rate 1–2% higher than their current rate to see how much EMI headroom they have if rates rise.
Home Loan Eligibility — What Lenders Look At
Before you calculate what your mortgage will cost, it's worth understanding what determines whether a lender will approve it — and at what rate.
Pair this mortgage calculator with our EMI calculator to model general loan repayments across any loan type and build the complete picture of your monthly obligations.
Why Include Property Tax and Insurance in Your Calculation?
Many first-time home buyers budget only for the loan EMI and are surprised to discover the additional monthly costs of owning a home. Including property tax and insurance in your mortgage calculator estimate removes that surprise.
Property Tax
Varies by city, municipal zone, property size, and usage type. In major Indian cities, annual property tax on a mid-segment residential property ranges from ₹10,000 to ₹60,000 or more.
Home Insurance
Fire and structure insurance is typically required by the lender as a mortgage condition. Annual premiums depend on property value and coverage but often range from ₹3,000 to ₹15,000 for standard properties.
Adding these optional figures to the calculator gives you the true monthly mortgage payment — the total outgoing that represents your real cost of homeownership, not just the loan repayment. This is the number you should budget against.
Frequently Asked Questions
1. What is a mortgage calculator and how does it work?
A mortgage calculator estimates your monthly home loan repayment based on the loan amount, interest rate, and loan term. It uses the standard amortisation formula to calculate how much of each payment goes towards principal and how much towards interest, and shows the total interest paid over the full loan period.
2. How is the monthly mortgage payment calculated?
The monthly payment is calculated using the formula: EMI = P × [i(1+i)^n] ÷ [(1+i)^n – 1], where P is the loan amount, i is the monthly interest rate (annual rate ÷ 12), and n is the total number of monthly payments. This mortgage calculator applies this formula instantly based on your inputs.
3. What is a good interest rate for a home loan in India?
Home loan interest rates in India currently range from approximately 8.5% to 11% depending on the lender, your CIBIL score, the loan amount, and whether the rate is fixed or floating. Rates linked to the RBI repo rate (RLLR-based loans) tend to be more transparent and adjust directly when the RBI changes rates.
4. How much home loan can I get on my salary?
Most lenders allow a total EMI obligation of up to 40–50% of your net monthly income. So if your net income is ₹1,00,000 per month, your total EMIs including the home loan should ideally not exceed ₹40,000–₹50,000. Use the calculator in reverse — enter a loan amount and tenure to see if the resulting EMI fits within this limit.
5. What is the difference between principal and interest in a mortgage?
Principal is the actual loan amount you borrowed — repaying it reduces your outstanding debt and builds equity. Interest is the lender's charge for providing the loan, calculated as a percentage of the outstanding principal. In the early years, most of each EMI is interest. As the loan matures, more goes towards principal.
6. What is mortgage amortisation?
Amortisation is the process of gradually repaying a loan through regular scheduled payments over time. Each payment reduces the outstanding principal slightly, which in turn reduces the interest charged in the next period. Over the full loan term, the loan is completely paid off. A mortgage calculator shows you this amortisation in action.
7. Should I choose a shorter or longer home loan tenure?
A shorter tenure means higher monthly EMIs but significantly lower total interest paid. A longer tenure reduces monthly pressure but increases the total cost of the loan substantially. The right choice depends on your income, cash flow, and financial goals. Use this mortgage calculator to compare the total interest paid across different tenures before deciding.
8. What is a floating rate home loan and how does it affect my EMI?
A floating rate home loan has an interest rate that changes based on market benchmarks — in India, typically the RBI repo rate. When the repo rate decreases, your EMI or loan tenure reduces. When it increases, your EMI rises. Most home loans in India today are floating rate. Use the calculator with a range of interest rate scenarios to understand how rate changes would affect your monthly payment.
9. Can I include property tax and insurance in this mortgage calculator?
Yes. The optional fields for Annual Property Tax and Annual Homeowners Insurance let you include these real-world costs in your monthly payment estimate. This gives you the true all-in monthly cost of homeownership — which is what you should use for budget planning, not just the loan EMI alone.
10. Is this mortgage calculator free to use?
Yes, completely free. No registration, no subscription, and no usage limits. Run as many scenarios as you need — comparing different loan amounts, tenures, interest rates, and tax and insurance figures — to find the combination that gives you the clearest picture of your home purchase costs.

The Clearest View of Your Home Purchase — Before You Commit
A mortgage is not just a monthly payment. It is a 15, 20, or 30-year financial commitment that shapes your budget, your savings capacity, and your financial flexibility for decades. The interest alone can add up to more than the original price of the home.
Getting clarity before you sign — on what your actual monthly outgoing will be, what the total cost of the loan is, and how different choices affect both — is the most valuable thing you can do before entering any lender conversation.
