Calculate monthly mortgage payments with down payment, rate, and tenure. View amortization schedule with yearly breakdown and principal vs interest charts.
About This Calculator
This Mortgage Calculator helps you estimate your monthly mortgage payments including principal and interest. It is designed for homebuyers, real estate investors, and homeowners looking to understand the true cost of financing a property. Simply enter the property price, your down payment, the expected interest rate, and the loan tenure to see a complete breakdown of your housing loan.
The calculator subtracts your down payment from the property price to determine the loan amount, then computes the monthly payment using the standard amortization (EMI) formula. Results include yearly amortization breakdowns showing how each payment is split between principal and interest, plus interactive charts that visualize your remaining balance over time and the total principal versus total interest paid. This helps you understand how different down payment amounts, interest rates, and loan terms affect your monthly budget and long-term borrowing costs.
Mortgage Formula:
Monthly Payment = P x r x (1+r)^n / [(1+r)^n - 1] where P is the loan amount (property price minus down payment), r is the monthly interest rate (annual rate divided by 12), and n is the total number of monthly payments.
How to Use:
Enter the property price and your down payment to calculate your loan amount. Input the expected annual interest rate and the loan tenure in years, then click Calculate to view your monthly payment, total amount payable, total interest, and a full yearly amortization schedule. The balance chart shows your declining mortgage balance over the loan term, while the breakdown chart compares total principal versus total interest paid.

Frequently Asked Questions
How does the Mortgage Calculator work?
Enter the property price, down payment, annual interest rate, and loan tenure. The calculator deducts your down payment from the property price and computes monthly mortgage payments using the standard EMI formula with full amortization schedule.
What is the mortgage payment formula?
Monthly Payment = P x r x (1+r)^n / [(1+r)^n - 1], where P is the loan amount (property price minus down payment), r is monthly interest rate, and n is total months. This is the standard amortizing loan formula used worldwide.
How does down payment affect mortgage?
A larger down payment reduces the loan amount, lowering monthly payments and total interest. In India, minimum 10-20% down payment is typical. In US, 20% down avoids PMI. In UK, 5-10% minimum deposit is common for first-time buyers.
What is the difference between mortgage and loan?
A mortgage is a specific type of loan used to purchase real estate, where the property serves as collateral. While general loans can be for any purpose (car, education, personal), mortgages are specifically for property and typically have longer tenures (15-30 years) and lower interest rates.
How can I lower my mortgage payments?
Lower mortgage payments by: 1) Making a larger down payment, 2) Negotiating a lower interest rate, 3) Extending the loan tenure (increases total interest), 4) Shopping for better mortgage deals, 5) Improving credit score before applying, 6) Considering government schemes for first-time buyers.
What is mortgage amortization?
Mortgage amortization is the gradual repayment of a home loan through regular monthly payments. Each payment covers both interest and principal. In early years, most of the payment goes toward interest; in later years, more goes toward principal. This is why making extra payments early saves the most interest.
What is the ideal mortgage tenure?
The ideal tenure balances affordable monthly payments with minimizing total interest. In India, 15-20 years is common; in the US, 30-year fixed is most popular; in the UK, 25-year terms are standard. Shorter tenures save interest, longer tenures reduce monthly burden.
Should I make extra mortgage payments?
Extra payments reduce principal faster, saving substantial interest over the loan term. Even one extra payment per year can reduce a 30-year mortgage to about 23 years. Check if your lender charges prepayment penalties before making extra payments.
