Plan your dream home with our precise monthly payment estimator.
Result includes Principal, Interest and Taxes.
Buying a home is one of the biggest financial decisions most people ever make, and knowing your real monthly payment before you sign anything is essential. Whether you're a first-time buyer comparing lenders, refinancing an existing loan, or an investor running numbers on a rental property, understanding exactly how much house you can afford is the foundation of a smart purchase.
Our Mortgage Calculator gives you an instant, accurate estimate of your monthly payment using the same standard amortization formula banks use internally. It's completely free, works on any device, and requires no sign-up — just enter your numbers and get results in real time.
Where: P = Monthly Payment, L = Loan Amount, c = Monthly Interest Rate (annual rate ÷ 12), n = Total Number of Monthly Payments.
The table below shows estimated Principal & Interest payments at a 6.5% fixed rate over a 30-year term, so you can quickly gauge what different loan sizes look like:
| Loan Amount | 30-Year Term (P&I) | 15-Year Term (P&I) | Total Interest (30-yr) |
|---|---|---|---|
| $100,000 | $632 | $871 | $127,540 |
| $150,000 | $948 | $1,307 | $191,310 |
| $200,000 | $1,264 | $1,742 | $255,080 |
| $240,000 | $1,517 | $2,091 | $306,120 |
| $300,000 | $1,896 | $2,614 | $382,620 |
| $400,000 | $2,528 | $3,485 | $510,160 |
| $500,000 | $3,160 | $4,356 | $637,700 |
Every standard mortgage payment is made up of four parts, commonly known by the acronym PITI:
This is the actual balance you owe the bank. Each month, a portion of your payment reduces this amount, slowly building your home equity. Early in the loan, only a small slice of your payment goes toward principal.
The fee charged by the lender for the use of their money. In the first years of a 30-year loan, the majority of your payment is interest — this is why paying extra toward principal early can save so much over time.
Property Taxes are set by your local government and are usually collected monthly by your lender and held in an escrow account, then paid on your behalf once or twice a year.
Homeowners Insurance (and PMI, if applicable) protects the lender and you in case of damage or default. Like taxes, this is often bundled into your monthly payment via escrow.
Here's how the numbers play out in real-world buying scenarios:
| Scenario | Home Price | Down Payment | Est. Monthly P&I |
|---|---|---|---|
| First-time buyer, starter home | $220,000 | $11,000 (5%) | $1,321 |
| Family home, 20% down | $350,000 | $70,000 (20%) | $1,769 |
| Upgrade home, suburban area | $450,000 | $90,000 (20%) | $2,275 |
| Investment / rental property | $275,000 | $55,000 (20%) | $1,391 |
| Loan Type | Pros | Cons |
|---|---|---|
| Fixed Rate | Predictable payments; peace of mind. | Rates may be higher initially. |
| Adjustable Rate (ARM) | Lower rates in early years. | Payments can spike if rates rise. |
| FHA Loan | Lower down payment requirements (as low as 3.5%). | Requires mortgage insurance premiums (MIP). |
| VA Loan | No down payment for eligible veterans. | Only available to qualifying service members. |
Many buyers focus only on the monthly payment and forget to check total interest paid over the full term. A lower monthly payment on a 30-year term can cost far more overall than a 15-year term.
A common mistake is calculating only Principal & Interest and assuming that's the full payment. Always add property tax and insurance estimates for a realistic PITI figure.
Sticking with the first lender you talk to can cost thousands. Get quotes from multiple banks or brokers — even small rate differences compound significantly over 30 years.
If your down payment is below 20%, you'll likely pay Private Mortgage Insurance until you build enough equity. Factor this into your monthly budget.
The word "mortgage" comes from Old French, roughly meaning "death pledge" — referring to the fact that the pledge ends when the debt is either paid off or defaulted on. The modern 30-year fixed-rate mortgage as we know it in the U.S. became widespread after the Federal Housing Administration was created in 1934, which standardized long-term, fully amortizing home loans and made homeownership accessible to a much larger portion of the population.
Understanding your mortgage payment before you start house hunting puts you in a stronger negotiating position and helps you avoid financial stress down the road. Use the calculator above to test different home prices, down payments, and interest rates until you find a monthly payment that fits comfortably within your budget — and always get pre-approved before making an offer.
