Mortgage Calculator – Estimate Home Loan EMI, Interest & Payments
Use our free Mortgage Calculator to estimate your monthly payments, total interest, and loan amortization. Calculate your home loan EMI easily based on loan amount, interest rate, and tenure.
How Mortgage Payments Work
A mortgage payment typically consists of four components known as PITI: Principal, Interest, Taxes, and Insurance. Each monthly payment reduces your loan balance while covering the cost of borrowing and property-related expenses.
Formula: EMI = P × r × (1+r)n / [(1+r)n − 1], where P = loan amount, r = monthly interest rate, n = total months. Early payments are mostly interest; over time, more goes toward principal.

Down Payment Impact ($350,000 Home at 6.5%, 30 Years)
| Down Payment | Loan Amount | Monthly P&I | Total Interest | PMI Needed? |
|---|---|---|---|---|
| 5% ($17,500) | $332,500 | $2,102 | $424,220 | Yes |
| 10% ($35,000) | $315,000 | $1,991 | $401,860 | Yes |
| 15% ($52,500) | $297,500 | $1,881 | $379,500 | Yes |
| 20% ($70,000) | $280,000 | $1,770 | $357,140 | No |
| 25% ($87,500) | $262,500 | $1,659 | $334,780 | No |
Putting 20% or more down eliminates PMI and significantly reduces total interest paid.
15-Year vs 30-Year Mortgage ($300,000 Loan)
| Feature | 15-Year (6.0%) | 30-Year (6.5%) |
|---|---|---|
| Monthly Payment | $2,532 | $1,896 |
| Total Interest | $155,683 | $382,633 |
| Total Paid | $455,683 | $682,633 |
| Interest Savings | $226,950 saved with 15-year | |
A 15-year mortgage costs more monthly but saves over $200K in interest on a $300K loan.
FAQ – Mortgage Calculator
What is a Mortgage Calculator?
A Mortgage Calculator helps you estimate your monthly mortgage payments, total interest, and total repayment amount based on your loan amount, interest rate, and loan term. It's an essential tool for planning home loans and budgeting.
How does a Mortgage Calculator work?
The calculator uses the principal loan amount, annual interest rate, and loan tenure to compute the fixed monthly payment (EMI). It also provides a detailed breakdown of interest and principal repayment over time.
What is the mortgage payment formula?
The formula is: EMI = P × r × (1+r)n / [(1+r)n − 1], where P = Loan Amount, r = Monthly Interest Rate (annual rate ÷ 12 ÷ 100), n = Number of Monthly Payments.
What is PITI in a mortgage?
PITI stands for Principal, Interest, Taxes, and Insurance — the four components of a typical monthly mortgage payment. This calculator lets you include all four for a complete picture.
What is PMI and when is it required?
Private Mortgage Insurance (PMI) is required when your down payment is less than 20% of the home price. It protects the lender if you default. PMI typically costs 0.5–1% of the loan amount annually and can be removed once you reach 20% equity.
Should I choose a 15-year or 30-year mortgage?
A 15-year mortgage has higher monthly payments but saves significantly on total interest. A 30-year mortgage offers lower monthly payments but costs much more over the life of the loan. Choose based on your monthly budget and long-term goals.
How much should I put down on a house?
Putting 20% down avoids PMI and reduces your loan amount. However, many programs allow 3.5–5% down. A larger down payment means lower monthly payments and less total interest paid.
Can I make extra payments to pay off my mortgage faster?
Yes. Making extra principal payments reduces your loan balance faster, saving thousands in interest and shortening your loan term. Even one extra payment per year can shave years off a 30-year mortgage.
What is an amortization schedule?
An amortization schedule shows how each payment is split between principal and interest over the loan term. Early payments are mostly interest, while later payments are mostly principal. This calculator provides a yearly amortization breakdown.
How accurate are the results?
The calculator provides accurate estimates based on standard formulas. Actual payments may vary depending on your lender's terms, fees, escrow requirements, or interest rate changes for adjustable-rate mortgages.
