Mortgage & Affordability Calculator
Most mortgage calculators ask you to guess at property taxes. In Fairfield County that guess is usually the largest error in the number. This one starts with Fairfield’s actual mill rate and the Connecticut assessment ratio, so the figure you see is closer to what you would actually write a check for.
A payment estimate is not a pre-approval. It is a starting point.
Fairfield’s mill rate is 19.19 for the fiscal year beginning July 2026. Connecticut assesses property at 70% of value, so the estimate is 1.343% of price per year. Uncheck for another town.
For a town other than Fairfield, enter the annual tax from the listing.
Estimated monthly payment
$7,711
$960,000 loan at 6.5% over 30 years, with 20% down.
- Principal & interest $6,068
- Property tax $1,343
- Insurance/HOA $300
- Mortgage insurance est. $0
With less than 20% down, most lenders add mortgage insurance until the loan reaches 80% of value. Shown here at an estimated 0.5% of the loan per year.
Car loans, student loans, minimum credit card payments. Not utilities or groceries.

Maximum purchase price
$1,713,537
At 6.5% over 30 years, with 18% down and mortgage insurance.
- Loan amount $1,413,537
- Down payment $300,000
- Estimated monthly payment $11,742
- Share of gross income 40%
More comfortable target
$1,312,193
Housing at 28% of gross income rather than the lender’s 43% ceiling — about $8,167 a month.
The maximum above uses a total debt-to-income ceiling of 43%, which is where most conventional lenders draw the line. Qualifying for a number is not the same as wanting to live at it. A lender may approve you for more or less depending on credit, reserves and loan program.
If you are thinking about buying in Fairfield County, I would be happy to walk through what these numbers look like against real listings, and introduce you to lenders who actually close on time.
These calculators are provided for educational purposes only and produce estimates, not loan offers. I am not a lender and this is not a commitment to lend. Actual payments depend on your credit, loan program, and the taxes and insurance assessed on the specific property. Property tax is estimated at Fairfield’s mill rate of 19.19 for the fiscal year beginning 1 July 2026 (October 2025 grand list), applied to an assessed value of 70% of price as required by Connecticut General Statutes § 12-62a. A property’s actual assessment is set by the Town and may differ from its purchase price. Verify all figures with your lender and the Town of Fairfield before relying on them.
