How much is a mortgage payment in Illinois?

For a typical $400,000 home in Illinois with a 20% down payment ($80,000) on a 30-year loan at 6.47%, the full monthly payment works out to about $2,863. That breaks down as $2,016 in principal and interest, $627 in property tax and $220 in homeowners insurance — so taxes and insurance add roughly $847 a month on top of the loan itself.

In Illinois, property tax is the bigger of those two costs. The calculator above uses Illinois's real figures by default, but every input is editable — drop in your own price, down payment, rate and HOA for an exact number, and add a loan type (FHA, VA or USDA) if you're not putting 20% down.

Illinois property tax and home insurance

Illinois's average effective property tax rate is 1.88% of a home's value — the 1st highest of the 50 states and DC (the 51st lowest). On a $400,000 home that's about $7,520 a year, or $627 a month, escrowed into your payment. Property tax is the part of a mortgage that varies most from state to state, which is why a national calculator can be well off for Illinois.

Average homeowners insurance in Illinois runs about $2,643 a year for $300k of coverage — $100 above the US average of $2,543, the 23rd highest in the country. It's close to the national norm, so insurance is a moderate part of your Illinois payment.

Illinois mortgage payment by home price

Because Illinois's tax rate and insurance are fixed shares of the cost, the monthly payment scales with the price. With 20% down at 6.47%:

$300,000 home → about $2,202/mo · $400,000 home → about $2,863/mo · $500,000 home → about $3,524/mo (all including Illinois tax and insurance).

Putting less than 20% down adds private mortgage insurance (PMI) until you reach 20% equity, and a lower rate or longer search for insurance can meaningfully cut the Illinois figure. Use the inputs above to model your own scenario and see the amortization schedule.

What's included in a Illinois mortgage payment (PITI)

A mortgage payment has four parts, often shortened to PITI: Principal, Interest, Taxes and Insurance — plus PMI if you put down under 20% and any HOA dues. In Illinois, principal and interest on a $320,000 loan come to $2,016, then Illinois's property tax ($627) and insurance ($220) are collected monthly into an escrow account and paid on your behalf.

This calculator computes all of PITI for Illinois, shows a full amortization schedule, and estimates how much an extra monthly payment or biweekly schedule would save you in interest over the life of the loan.
