Mortgage Calculator
Calculate your monthly mortgage payment and view a complete amortization schedule for any home loan.
What Is a Mortgage Calculator?
A mortgage calculator is a financial tool that helps you estimate monthly home loan payments before signing a mortgage agreement. It computes your monthly EMI, total interest paid over the loan term, and complete amortization schedule based on three inputs: loan amount, interest rate, and tenure.
Whether you're buying a home in Mumbai, Delhi, New York, London, or Toronto, the mortgage math works identically. This free mortgage calculator works without signup, requires no personal data, and instantly delivers results — making it ideal for comparing offers from multiple lenders or testing different loan scenarios.

How Mortgage Payments Are Calculated
Every mortgage worldwide uses the standard amortization formula:
M = P × [r(1+r)n] / [(1+r)n − 1]
Where:
- M = Monthly mortgage payment
- P = Principal loan amount (home price minus down payment)
- r = Monthly interest rate (annual rate ÷ 12 ÷ 100)
- n = Total monthly payments (loan term in years × 12)
This formula calculates pure principal and interest. Your actual monthly housing cost typically includes additional components — property taxes, homeowners insurance, and HOA fees in the US, or municipal taxes and maintenance in India.
Real-World Example
For a ₹50,00,000 home loan at 8.5% interest for 20 years:
- P = 50,00,000
- r = 8.5 ÷ 12 ÷ 100 = 0.00708
- n = 20 × 12 = 240 months
Monthly Payment = ₹43,391
Over 20 years, total payment = ₹1,04,13,840. Of this, ₹54,13,840 is interest — more than the original loan amount!
Mortgage Rates Comparison: India vs Global
Home loan interest rates vary significantly by country and economic conditions. Here's a 2026 snapshot of typical mortgage rates worldwide:
| Country | Typical Rate Range | Common Tenure | Rate Type |
|---|---|---|---|
| India | 8.50% – 9.50% | 20–30 years | Floating (mostly) |
| USA | 6.50% – 7.50% | 15 or 30 years | Fixed (mostly) |
| UK | 4.50% – 6.00% | 25–35 years | Mixed |
| Canada | 5.00% – 6.50% | 25–30 years | Fixed (5-year reset) |
| Australia | 5.50% – 6.50% | 25–30 years | Variable |
For Indian borrowers, the major lenders (SBI, HDFC, ICICI, Axis Bank, Kotak) offer competitive rates that vary by 0.10-0.25% based on credit score, loan amount, and property location.
How to Use This Mortgage Calculator
The calculator above is designed for simplicity:
- Enter Loan Amount — The principal you need to borrow (home price minus down payment)
- Input Interest Rate — Annual rate in percent (e.g., 8.5 for 8.5%)
- Specify Loan Term — Tenure in years (15, 20, 25, or 30 years typically)
- View Results — See monthly payment, total interest, total payment, and amortization schedule
The amortization schedule reveals how each payment splits between principal and interest — crucial information that helps you make informed prepayment decisions.
What Most Homebuyers Get Wrong
Mistake 1: Focusing Only on Monthly Payment
Many buyers compare loans solely by monthly payment, choosing the lowest one. This is a costly mistake. A 30-year mortgage may have lower monthly payments than a 15-year, but you'll pay nearly double in total interest.
Example: ₹50 lakh loan at 9%:
| Tenure | Monthly Payment | Total Interest |
|---|---|---|
| 15 years | ₹50,713 | ₹41,28,372 |
| 20 years | ₹44,986 | ₹57,96,712 |
| 30 years | ₹40,231 | ₹94,83,310 |
The 30-year mortgage saves ₹10,482/month vs 15 years — but costs ₹53.5 lakhs more in interest over the loan life.
Mistake 2: Ignoring the True Cost of Homeownership
The mortgage payment is just one slice. Total housing cost includes:
- Property tax: 0.5-2% of property value annually (varies by city)
- Home insurance: 0.1-0.3% of property value annually
- Maintenance reserve: 1-2% of property value annually
- Society/HOA fees: ₹2,000-10,000/month in apartment complexes (India)
- Utility costs: Higher for larger homes
A ₹50 lakh home with ₹45,000 mortgage payment often costs ₹55,000-60,000 monthly in true housing expenses.
Mistake 3: Skipping the Prepayment Strategy
For a 20-year, ₹50 lakh loan at 8.5%, paying just one extra EMI per year cuts the loan tenure by approximately 3 years and saves ₹8-10 lakhs in interest. This applies globally — the same strategy works for mortgages in the US, UK, or Australia.
How to Get the Best Mortgage Rate
Lenders offer different rates based on borrower risk profile. Here's how to qualify for the lowest rates:
- Maintain credit score above 750 (CIBIL in India, FICO in US, Experian in UK) — This alone can save 0.5-1% on interest rate
- Higher down payment (20%+) — Reduces lender risk and often unlocks better rates
- Stable employment history (2+ years) with consistent income documentation
- Low debt-to-income ratio — Total EMIs should be under 40-50% of income
- Shop with multiple lenders — Get quotes from at least 3-4 banks before committing
- Negotiate processing fees — These are often waived or reduced for good profiles
- Consider working with a mortgage broker for access to wholesale rates
Fixed vs Floating Rate Mortgages
One of the most important decisions in any mortgage:
Fixed-rate mortgages: Interest rate stays constant for the entire tenure (or a fixed initial period). Provides predictability but typically starts 1-2% higher than floating rates. Best for: those who value payment certainty, expect rates to rise, or are on tight budgets.
Floating/Variable-rate mortgages: Rate changes with benchmark rates (RBI repo rate in India, Federal Funds Rate in US). Usually starts lower but payments can increase. Best for: borrowers who can absorb payment fluctuations, expect rates to fall, or plan to prepay aggressively.
In India, over 80% of home loans are floating-rate. In the US, 30-year fixed dominates. Globally, the answer depends on rate trends and personal risk tolerance.
Tax Benefits of Home Loans
Home loans offer significant tax advantages in most countries:
In India:
- Section 80C: Up to ₹1.5 lakh deduction on principal repayment
- Section 24(b): Up to ₹2 lakh deduction on home loan interest (for self-occupied property)
- Section 80EEA: Additional ₹1.5 lakh for first-time homebuyers on affordable housing
In USA: Mortgage interest deduction (up to $750,000 in loan principal), property tax deduction (capped at $10,000 SALT)
In UK: No mortgage interest deduction for residential properties (changed in 2017)

Frequently Asked Questions
How is mortgage payment calculated?
Monthly payment = P × r(1+r)n / [(1+r)n − 1], where P is principal, r is monthly interest rate, and n is total months. This calculator handles the math automatically.
What is amortization?
Amortization is paying off a loan with regular payments where each payment includes both principal and interest. Early payments are mostly interest; later payments are mostly principal.
Does this include taxes and insurance?
No. This calculator shows only principal and interest. Add property tax (typically 0.5-2% of property value annually) and home insurance (0.1-0.3% annually) to get true housing costs.
What is a good mortgage rate?
In India (2026), home loan rates are typically 8.5-9.5%. In the US, 6.5-7.5%. UK: 4.5-6%. Anything within 0.5% of the lowest available rate is considered good.
Should I choose 15 or 30 year mortgage?
15-year mortgages have higher monthly payments but save dramatically on total interest. 30-year offers lower payments and flexibility. Choose based on income stability and total cost tolerance.
Can I prepay my mortgage without penalty?
In India, RBI mandates no prepayment penalty on floating-rate home loans for individuals. In the US, most modern mortgages allow penalty-free prepayment. Always verify with your specific lender.
What credit score do I need for a mortgage?
India: CIBIL 750+ for best rates. USA: FICO 740+ for prime rates. UK: Experian 881+. Lower scores still qualify but at higher interest rates (often 1-2% more).
How much can I afford to borrow?
Total monthly debt obligations (including mortgage) should stay under 40-43% of gross income. Use our EMI Calculator to model your affordability.
Is this calculator accurate for SBI, HDFC, ICICI mortgages?
Yes. The mortgage formula is universal — banks worldwide use identical math. Differences in actual payments are usually within ₹100 due to rounding methods.
Does this work for US/UK mortgages?
Yes, the formula is universal. Enter amounts in your local currency. The calculator handles any currency since math depends only on numerical values.
