US mortgage calculator: your monthly cost and the cash you need

In Europe a mortgage payment is mostly interest and repayment. In the United States the monthly bill also carries property tax and home insurance, and both depend on where you buy. This calculator puts them together and shows the cash you need on the day you close.

The starting example is an $850,000 home in Boston with 20% down at 7.32%, the Freddie Mac 30-year average for the week of 22 October 2026. Change any field to match your plans. This is an estimate for planning. It is not a loan offer, and it leaves out the items listed under "What is not included" below.

Three worked examples

The same sums for three typical situations, each at 7.32% over 30 years and before home insurance. They show how much the place changes the answer.

ExampleLoanLoan paymentProperty taxMonthly totalCash at closing
Boston flat, $850,000, 20% down$680,000$4,671$878$5,549$187,000 to $212,500
Orlando house, $439,000, 25% down (county average tax)$329,250$2,262$300$2,562$118,530 to $131,700
Philadelphia row house, $400,000, 10% down$360,000$2,473$467$2,940$48,000 to $60,000

The Philadelphia example has less than 20% down, so private mortgage insurance would be added to the monthly total, and the city's transfer tax would add to the cash needed. The Orlando figure uses the county's average tax, which understates what a new non-resident owner pays.

How to read the result

Loan payment. Principal and interest on a fixed-rate loan that is fully repaid over the term. On a 30-year fixed loan this amount never changes.

Property tax. Charged by the town, city or county as a percentage of assessed value, and usually collected by your lender each month into an escrow account. It can rise each year. In Florida it is reset to your purchase price after you buy.

Home insurance. Required by every lender. We leave it at zero until you enter a quote, because premiums differ too much between an inland flat and a house on the coast to guess. Flood insurance, where needed, is a separate policy.

Cash needed at closing. Your down payment plus closing costs of typically 2% to 5% of the price. Lenders following Fannie Mae's rules need funds from abroad to be converted into dollars and held in a US account before closing, so plan the transfer early.

Conforming or jumbo. Loans up to the local conforming limit can be sold to Fannie Mae and Freddie Mac and are the standard product. Larger loans are jumbo loans, priced by each lender on its own terms.

What is not included

  • Private mortgage insurance, usually charged with less than 20% down on a conventional loan.
  • Flood insurance and separate wind cover, which matter most in Florida and on the New England coast.
  • Community Development District assessments in some Florida communities.
  • Local taxes at purchase beyond ordinary closing costs, such as land bank fees, transfer taxes and New York's mortgage recording tax.
  • Utilities, heating and maintenance.
  • The effect of your immigration status on which loans and rates are open to you.

That last point matters most. A buyer who lives in Europe will usually be offered a foreign national loan with a larger down payment and a higher rate than the average used here. See how your status decides the loan, then pick your area in the location guides for the local costs.
