Illinois Mortgage Calculator - Monthly Payment with Taxes, PMI & Insurance
Illinois property taxes are among the highest in the country and are set locally by overlapping districts. This state page uses a broad local property-tax estimate and the state real estate transfer tax; county and city pages override high-volume markets such as Chicago, Naperville, Joliet, and Aurora. On a $400,000 Illinois planning example with 20% down at 6.5% for 30 years, principal and interest are about $2,023; at ~2.10% statewide property-tax planning rate, tax escrow is about $700/mo, for estimated PITI near $2,823 before PMI. Illinois property taxes are often among the highest nationally, so escrow can rival principal and interest on a matched price.

Frequently Asked Questions
Why are Illinois property taxes so important for mortgage estimates?
Illinois escrow payments can be heavily affected by school, municipal, county, park, and special district taxes. A principal-and-interest-only estimate can materially understate monthly cost. Use this state mortgage calculator to combine that assumption with principal, interest, insurance, and PMI, then drill into county or city pages when you have a specific address.
What Illinois buyer assistance is modeled?
The state file models IHDA-style down payment assistance as a conservative percentage of loan amount capped at a planning maximum. Use this state mortgage calculator to combine that assumption with principal, interest, insurance, and PMI, then drill into county or city pages when you have a specific address.
What is a sample Illinois PITI on $400,000?
With 20% down at 6.5% for 30 years, principal and interest are about $2,023. At ~2.10% statewide property-tax planning rate, monthly escrow is about $700; with $100 insurance, estimated PITI is about $2,823 without PMI. Drill into county or city calculators for address-level millage.
Does this mortgage calculator include taxes and insurance?
Yes. This calculator estimates your full monthly housing payment by combining principal and interest with property taxes, homeowners insurance, and PMI when your down payment is below 20%. The result reflects a PITI-style payment rather than principal and interest alone, which helps you compare homes and loan scenarios more realistically before talking to a lender.
When does PMI apply on a mortgage?
Private Mortgage Insurance (PMI) typically applies when your loan-to-value ratio exceeds 80%, meaning your down payment is less than 20% of the purchase price. PMI is usually added to the monthly payment until you reach sufficient equity. This calculator includes PMI in the estimate when your inputs trigger it, so you can see how a smaller down payment affects affordability.
