Calculate your monthly home loan EMI, total interest payable, and see the full payment breakdown instantly.
This tool calculates your monthly mortgage payment, total interest paid, and full amortization schedule based on the home price, down payment, interest rate, and loan term. It's essential for budgeting a home purchase and comparing different mortgage offers.
Loan Amount = Home Price − Down Payment. Monthly Payment (Principal + Interest) = P × [r(1+r)ⁿ] ÷ [(1+r)ⁿ − 1], where P is the loan amount, r is the monthly interest rate, and n is the total number of monthly payments. Property taxes, insurance, and HOA fees are often added separately for a full monthly housing cost estimate.
Enter the home price, down payment, interest rate, and loan term, and the calculator returns your estimated monthly payment, total interest, and total cost over the life of the loan.
Example: A $400,000 home with a 20% down payment ($80,000), financed at 6.5% over 30 years, results in a loan amount of $320,000 and a principal-and-interest monthly payment of approximately $2,022.
Why does a 30-year mortgage have lower payments than a 15-year mortgage for the same loan amount? Spreading the same loan amount over more payments (30 years vs. 15) lowers each individual payment, though this comes at the cost of significantly more total interest paid over the life of the longer loan.
What does "PITI" mean in mortgage calculations? PITI stands for Principal, Interest, Taxes, and Insurance — the four components that typically make up a complete monthly mortgage payment, beyond just the base principal-and-interest amount this calculator's core formula produces.
How does down payment size affect my mortgage? A larger down payment reduces the loan amount needed, lowering both the monthly payment and total interest paid, and in some cases can help avoid additional costs like private mortgage insurance (PMI) required for smaller down payments.
Why do mortgage rates change over time? Mortgage rates fluctuate based on broader economic factors, including central bank policy, inflation expectations, and bond market conditions, meaning the rate available today may differ meaningfully from rates available in the past or future.
Should I choose a fixed-rate or adjustable-rate mortgage? A fixed-rate mortgage keeps the same interest rate for the entire loan term, providing payment stability, while an adjustable-rate mortgage (ARM) typically starts with a lower rate that can change periodically — the better choice depends on your risk tolerance and how long you plan to keep the loan.
A monthly mortgage payment typically bundles together several components beyond just the loan principal and interest — property taxes, homeowner's insurance, and in many cases private mortgage insurance (PMI) if your down payment is below a certain threshold, are often collected monthly by the lender and held in an escrow account. This calculator helps you understand how each of these pieces contributes to your total monthly obligation, since focusing only on principal and interest can significantly understate what you'll actually need to budget for.
A larger down payment reduces the amount you need to borrow, which lowers both your monthly payment and the total interest you'll pay over the life of the loan, and can often help you avoid private mortgage insurance altogether if it pushes your loan-to-value ratio below the typical 80% threshold. Running different down payment amounts through this calculator lets you see directly how much of a difference even a modest increase in your upfront payment can make.
Comparing a 15-year mortgage against a 30-year mortgage on the same loan amount typically shows a significant difference in both monthly payment size and total interest paid — the shorter term carries a higher monthly payment but usually a meaningfully lower interest rate and dramatically less total interest overall, while the longer term offers more monthly budget flexibility at the cost of paying substantially more in interest over time.
A fixed-rate mortgage keeps the same interest rate for the entire loan term, offering predictable payments, while an adjustable-rate mortgage typically starts with a lower rate that can change periodically based on market conditions, offering potential short-term savings but less long-term predictability. Running both scenarios through this calculator can help you see the payment difference upfront and understand your risk if rates rise later during an adjustable-rate loan.
An amortization schedule breaks down every single payment over the life of your mortgage, showing exactly how much of each payment goes toward interest versus principal, and reviewing this breakdown can be genuinely eye-opening, since early payments are often weighted heavily toward interest with only a small portion actually reducing your loan balance. Understanding this pattern helps explain why extra payments made early in a mortgage term have an outsized impact on reducing total interest.
How does a larger down payment affect total mortgage cost? A larger down payment reduces the loan principal needed, which lowers both the monthly payment and the total interest paid over the life of the loan, while also potentially helping avoid additional costs like mortgage insurance required for smaller down payments.
Why do mortgage calculators often show an amortization schedule alongside the monthly payment? Seeing the full schedule reveals exactly how the interest-to-principal ratio shifts over the loan term, helping borrowers understand why the loan balance decreases slowly at first and much faster in later years.
