Buying a $500,000 house is the new normal. As of the second quarter of 2026, the average purchase price of a single-family home was $502,700 — down from an all-time high of $541,300 in the 4th quarter of 2025, according to the Federal Reserve Bank of St. Louis. With 10% down and a 7% mortgage rate on a 30-year loan, that will cost about $3,000 a month, considering just principal and interest.
Here’s how the math breaks down and how to plan for a mortgage on a $500,000 home.
What is the total cost of a mortgage on a $500,000 house?
How much will a half-million-dollar home cost you these days? Here’s the total cost of principal and interest payments for a mortgage on a $500,000 house, broken down by two popular mortgage loan terms: 30-year and 15-year fixed-rate loans.
30-year fixed-rate mortgage
- Lifetime cost over 30 years: $1,077,790
- Total interest paid: $627,790
- Assumes 10% down, 7% interest rate
15-year-fixed-rate mortgage
- Lifetime cost over 15 years: $694,513
- Total interest paid: $244,513
- Assumes 10% down, 6.25% interest rate
As you can see, there’s quite a bit of interest savings with a 15-year mortgage, to the tune of over $380,000. These mortgages typically have lower interest rates than 30-year mortgages. The shorter loan term also means a speedier payoff, significantly reducing your total interest paid.
You could save even more on interest if you qualify for a VA loan or an FHA loan, which can have even lower interest rates and perks than other mortgages on the market.
How much is a $500,000 mortgage monthly?
Your monthly principal-and-interest payment on a $500,000 mortgage depends on three main factors: mortgage type, interest rate, and term length. Here’s what your payment might look like each month based on three popular types of mortgages.
Our sample rates start at 7% for conventional mortgages, 6.75% for FHA mortgages, and 6.50% for VA mortgages — this reflects that FHA mortgage rates are usually lower than conventional ones, and VA rates are typically the lowest of the three.

The Federal Housing Administration insures FHA loans, which often have more lenient qualification criteria and lower down payment requirements than conventional loans.

Other costs to consider with a mortgage on a $500,000 house
The costs of a mortgage on a $500,000 house go beyond your monthly principal and interest payment. Owning a home comes with various short- and long-term costs; knowing which costs are common can help you budget and ensure you're buying a home you can afford.
Short-term costs
You'll run into short-term expenses when you buy your home. These are typically known as closing costs — one-time expenses you'll pay just before purchase or at closing — and generally run between 2% and 5% of your total loan amount. Some expected costs include:
- Down payment
- Home appraisal
- Home inspection
- Mortgage origination fee
- Title search and title insurance fee
- Underwriting fees
- Discount points
- Real estate agent commissions
Long-term costs
The most common long-term costs you'll encounter as a homeowner are your home maintenance expenses, property taxes, and homeowners insurance. You also might have to pay for mortgage insurance or homeowners' association dues.
Most mortgage payments include escrow payments, which are additional dollars added to your monthly bill that your lender sets aside to pay your property taxes and insurance. Your lender communicates directly with your insurance company and the local tax assessor's office to get accurate figures.
If you have a conventional mortgage and make a down payment that's less than 20%, you may be required to pay private mortgage insurance (PMI). This insurance, generally ranging from $30 to $70 monthly for every $100,000 you borrow, protects the lender if you default on your loan. For a $500,000 mortgage, that would come to $150 to $350 per month. Once your loan balance reaches 80% of the home's original value, you can usually stop paying this added cost.
With an FHA loan, you would pay an FHA mortgage insurance premium regardless of your down payment size. The MIP is 1.75% of the loan amount at closing, and then you pay an annual premium (usually split into monthly installments), and the cost varies based on several factors.
Costs for maintenance can vary. General upkeep over time can include plumbing and appliance repairs, a new roof, and different renovations and upgrades to keep a home safe and cozy.
Amortization schedule on a $500,000 mortgage
Whether you have a $500,000 or $5 million mortgage, all mortgages are amortized loans. When you make your monthly payments, those payments get split between the principal and interest. Most of your monthly mortgage payment will go toward interest since your outstanding principal is higher at the beginning of your mortgage term. Over time, however, more and more of your payment will go toward the principal.
Here's a mortgage amortization schedule on a $500,000 15-year fixed-rate mortgage, assuming a 7% rate and 0% down payment, to show you how that works. For the sake of simplicity, we'll show how it would work if you started making payments at the beginning of 2027.
| Date | Total principal paid | Total interest paid | Year-end balance |
|---|---|---|---|
| 2027 | $17,867.29 | $31,568.27 | $482,132.71 |
| 2028 | $38,707.91 | $64,657.34 | $461,292.09 |
| 2029 | $61,055.09 | $96,239.85 | $438,944.91 |
| 2030 | $85,017.76 | $126,206.88 | $414,982.24 |
| 2031 | $110,712.69 | $154,441.65 | $389,287.31 |
| 2032 | $138,265.11 | $180,818.93 | $361,734.89 |
| 2033 | $167,809.30 | $205,204.44 | $332,190.70 |
| 2034 | $199,489.23 | $227,454.20 | $300,510.77 |
| 2035 | $233,459.32 | $247,413.81 | $266,540.68 |
| 2036 | $269,885.10 | $264,917.72 | $230,114.90 |
| 2037 | $308,944.10 | $279,788.41 | $191,055.90 |
| 2038 | $350,826.69 | $291,835.53 | $149,173.31 |
| 2039 | $395,736.97 | $300,854.94 | $104,263.03 |
| 2040 | $443,893.81 | $306,627.79 | $56,106.19 |
| 2041 | $495,531.92 | $308,919.38 | $4,468.08 |
| 2042 | $500,000.00 | $308,945.44 | $0.00 |
The minimum down payment depends on your loan type. For a conventional loan, you can put down as little as 3% ($15,000), while FHA loans require 3.5% ($17,500). VA and USDA loans allow 0% down. However, putting down 20% ($100,000) allows you to avoid Private Mortgage Insurance (PMI) and significantly lowers your monthly payment.
Closing costs typically range from 2% to 5% of your total loan amount. For a $500,000 mortgage, expect to pay between $10,000 and $25,000 in upfront fees. This covers the home appraisal, title search, loan origination fees, attorney fees, and your initial escrow deposit for taxes and insurance.
Your credit score directly dictates your interest rate. A borrower with an excellent score (760+) might secure a 6.00% rate, while someone with a 620 score might be offered 7.50%. On a $500,000, 30-year mortgage, that 1.5% rate difference adds roughly $500 to your monthly payment and costs an extra $180,000 in interest over the life of the loan.
A 30-year mortgage stretches out the timeline, giving you lower, more flexible monthly payments. A 15-year mortgage will increase your monthly payment by $1,000 or more, but you will secure a lower interest rate, build home equity much faster, and save hundreds of thousands of dollars in total interest.
If you have a fixed-rate mortgage, your core Principal & Interest (P&I) payment will never change. However, your total monthly bill likely includes property taxes and homeowners insurance held in an escrow account. If your local property taxes or insurance premiums go up, your mortgage servicer will increase your total monthly payment to cover the difference.
