The gap

What most mortgage calculators miss

A national mortgage calculator uses one tax rate, one insurance number, and one set of fee rules. The actual cost of owning a home in the United States depends on which state the house sits in, how old the roof is, and what kind of loan you qualify for.

Property tax

A $400,000 home in New Jersey costs $8,920 a year in property tax. The same house in Hawaii: $1,120. The ratio is almost eight to one. Most calculators use a national average of around 1 percent and get both wrong, which is why your actual escrow bill can shock you.

Home insurance

Florida homeowners pay $7,136 a year on average because of hurricane exposure and litigation. Vermont averages $1,100. That is roughly $500/month baked into the mortgage payment before you touch anything else. Oklahoma, Nebraska, and Kansas run high too, thanks to hail and tornadoes.

Loan type fees

FHA MIP stays with the loan for life unless you refinance to a conventional loan. VA has a one time funding fee of around 2.15 percent, waived for disabled veterans. USDA charges a 1 percent upfront fee plus 0.35 percent annual. Conventional PMI drops off at 80 percent loan to value. Each one changes the monthly math by hundreds.

Transfer taxes

Delaware buyers pay 2.99% of the sale price in closing costs. Wyoming, Missouri, and Montana charge no state transfer tax at all. On a $400,000 home that is around $12,000 of difference you only see at the closing table, usually too late to adjust the budget.

Worked example

$300,000 home, 20% down, 30 year fixed

Same loan amount, same credit profile, same interest rate. The monthly payment changes significantly based on where the house is.

Methodology

How the calculators work

Each state calculator uses the standard mortgage amortization formula to compute principal and interest, then layers on property tax, home insurance, PMI or MIP, and HOA fees to produce the full monthly PITI payment. All math runs in your browser; nothing is sent to a server.

Rate data

Current mortgage rates come from FRED, the Federal Reserve Economic Data service operated by the St. Louis Fed. The 30 year fixed conventional rate updates weekly, every Friday morning after the Thursday release.

Tax and insurance figures

State level effective property tax rates are compiled from the Tax Foundation's annual report and WalletHub's 2026 analysis. Average homeowners insurance premiums use the latest numbers from Insurance.com and Bankrate, based on a standardized policy with $300,000 dwelling coverage and a $1,000 deductible. Your actual premium depends on your specific home, roof age, claim history, and credit score.

PMI and loan rules

Private mortgage insurance assumes 0.75 percent annual rate, the industry average for conventional loans. FHA MIP uses the current 0.55 percent annual rate with the 1.75 percent upfront fee financed into the loan. VA funding fees follow the first use, 0 percent down schedule. All of these can vary; the calculator provides a reasonable estimate, not a quote.

What we do not include

Closing costs, inspection fees, escrow prepaid items, and ongoing maintenance are not included in the monthly payment estimate. The true cost of homeownership guide walks through what else to budget for.

Frequently asked

About these calculators

What is PITI?

PITI stands for principal, interest, taxes, and insurance. It is the full monthly payment a homeowner makes, not just the loan portion. Many calculators show only principal and interest, which can understate the real cost by 30 to 50 percent.

Why do property taxes vary so much between states?

States without income tax, like Texas and Florida, lean more heavily on property tax to fund local services. States with high home values, like Hawaii, can keep tax rates low because the base is already large. The result is dramatic variation, from 0.28 percent in Hawaii to 2.23 percent in New Jersey.

Do these calculators include PMI?

Yes. If your down payment is below 20 percent on a conventional loan, the calculator adds private mortgage insurance to the monthly payment. It also handles FHA MIP, VA funding fees, and USDA guarantee fees.

How often are mortgage rates updated?

Rates are pulled weekly from FRED, the Federal Reserve Economic Data service, every Friday. The number shown on each calculator reflects the most recent published 30 year fixed conventional average.

Can I compare two states side by side?

Not yet. For now, open two calculators in different browser tabs and enter the same purchase price and down payment in each.

Is this financial advice?

No. The calculators and guides are informational tools built on public data. For personal mortgage advice, work with a licensed mortgage professional in your state.
