Property taxes and insurance vary enormously across the country — from under 0.3% in Hawaii to 2.2%+ in New Jersey. Pick your state for a mortgage calculator pre-loaded with local property-tax rates, typical home values and average insurance, plus the live national rate and colorful payment-breakdown charts.
Two buyers with identical loan amounts and interest rates can have very different monthly payments depending on where they live. The reason is the two largest escrow add-ons: property taxes and homeowners insurance. Property-tax rates range from roughly 0.29% of a home's value per year in Hawaii to over 2.2% in New Jersey and Illinois — a difference that can mean hundreds of dollars a month on the same house. Homeowners insurance varies just as widely, from under $1,000 a year in low-risk states like Oregon and Vermont to well over $5,000 in hurricane-exposed Florida and tornado-prone Oklahoma. A national mortgage calculator that ignores these state differences can understate your real payment by $300 to $900 a month.
Each calculator on this page is pre-loaded with that state's average effective property-tax rate, typical home value and average insurance premium, and the interest-rate field pulls the current national 30-year average so your estimate reflects today's market. Adjust any field to match your actual home, down payment and loan terms. Whether you're comparing the cost of buying in a no-income-tax state like Texas, Florida or Washington, weighing high-property-tax states like New Jersey or Illinois, or budgeting for an expensive market like California or Hawaii, these tools give you a realistic, all-in monthly payment instead of a misleading principal-and-interest figure. Remember that rates and tax figures vary by county and lender — use these calculators for planning, then confirm exact numbers with a lender's official Loan Estimate.
