What this Wisconsin mortgage calculator does
It is the full monthly-cost calculator, loaded with Wisconsin assumptions: a 1.32% property tax rate and $1,897 a year for insurance. You get principal and interest, property tax, insurance, PMI when your down payment is under 20%, and HOA dues, plus a payoff schedule and the effect of extra payments. Every figure is editable, so it works for a Madison suburb, a Milwaukee neighborhood or a northern Wisconsin home.
How it works for Wisconsin buyers
Enter the price, down payment, rate and term. Wisconsin’s tax rate differs by municipality and school district, so the best number to enter is the property’s most recent tax bill divided by its price. Remember the bill may not reflect a value close to the price you are paying, so ask whether the municipality has revalued recently. Copy the link to share your result.
How Wisconsin property tax works
Wisconsin assessors are required to value property at its market value as of January 1. The tax is the assessed value times a net rate made up of the rates of each overlying jurisdiction, minus the state school levy credit. Because municipalities can assess at different percentages of market value, the state calculates equalized values so levies are shared fairly. For a buyer the practical point is simple: the effective rate on the price you pay depends on how the assessed value compares with market value, which is why published state averages vary so much. After a revaluation, the assessed value moves toward market value and the bill can rise.
Worked example: $340,000 home, 20% down, 6.5%
The $272,000 loan has principal and interest of $1,719.23. At 1.32%, property tax is $4,488 a year, or $374.00 a month. With $1,897 a year for insurance ($158.08 a month), the payment is $2,251.31.
Moving the tax rate from 1.20% to 1.82% changes the payment by about $176 a month. Moving the insurance estimate from $1,536 to $2,465 changes it by about $77. In Wisconsin, property tax moves your payment more than insurance does. This example uses illustrative assumptions, not a quote.
Closing costs in Wisconsin
Wisconsin’s real estate transfer fee is $3 per $1,000 of the sale value, and the seller pays it. On a $340,000 sale that is $1,020, which does not come out of your cash to close. Your closing costs are the usual lender, title and recording charges.
More to know about buying in Wisconsin
Compare assistance programs early
WHEDA’s first mortgages and its two down payment programs have different income limits, and Capital Access has limited funding. In many cases a WHEDA mortgage with down payment help can provide nearly full financing. Run the loan types through the FHA, VA and USDA calculators, and see what you can buy with the affordability calculator.
Look at the tax bill, not just the rate
Ask for the last two tax bills, and ask the municipality whether a revaluation is planned. If assessments are well below market, a revaluation could raise the bill after you buy.
Insurance and weather
Wind, hail and heavy snow drive claims. Ask about separate wind or hail deductibles, and ask about flood coverage if the property is near water, since standard policies exclude flood.

Frequently asked questions
What is the average property tax rate in Wisconsin?
Wisconsin is a higher property tax state. Estimates of the statewide effective rate range from about 1.25% to 1.6% of home value depending on the method. The Legislative Fiscal Bureau estimates the net tax on a median-valued home at about 1.25% of its value for 2026-27, and the Tax Foundation figure cited in 2026 guides is 1.32%, which the calculator uses. Milwaukee County is among the highest at roughly 1.8%, and some northern counties run near 1.2%, so replace the default with your area.
How is Wisconsin property tax calculated?
The local assessor values the property, ideally at full market value as of January 1. The net tax is the assessed value times the net assessed value rate, which adds the rates of each taxing jurisdiction (county, municipality, school district and technical college) and subtracts the state school levy credit. Credits such as the lottery and gaming credit on a primary residence are applied on the bill. Because assessments can lag market values, compare the property’s actual tax bill with its price.
Who pays the real estate transfer fee in Wisconsin?
The seller pays it. Wisconsin charges a real estate transfer fee of $3 per $1,000 of the value, collected by the county, so it is $1,020 on a $340,000 sale. There is no buyer-paid state transfer tax, though you will still pay normal closing costs.
When are Wisconsin property taxes due?
Property tax bills are issued in December, and the full amount or the first installment is due by January 31. If you pay in installments, the second payment is typically due by July 31. Most buyers with a mortgage pay through escrow, so ask what your lender will collect.
Does Wisconsin offer down payment assistance?
Yes. The Wisconsin Housing and Economic Development Authority (WHEDA) offers Advantage Conventional (620 minimum credit score) and Advantage FHA (640) first mortgages with two down payment assistance options, Easy Close and Capital Access, which can be used with either. Capital Access was relaunched on a limited basis in January 2026 with its own, generally lower, income limits. Lender sites describe Easy Close as at least $1,000 up to 6% of the price, but confirm current amounts with WHEDA.
Are there Wisconsin property tax credits?
Yes. The lottery and gaming credit applies to a primary residence, a school levy tax credit and a first dollar credit appear on the bill, and the income-based Homestead Credit helps lower-income households. Amounts change each year and depend on where you live, so ask your municipal treasurer or the Department of Revenue.
How much is homeowners insurance in Wisconsin?
Published averages range from roughly $1,500 to about $2,500 a year, depending on the source and coverage amount. LendingTree puts the 2026 average near $1,897, which the calculator uses, and NerdWallet reports about $2,465. Wind, hail and heavy snow are the main risks, and standard policies exclude flood, so ask about wind and hail deductibles and about flood coverage if the property is near water.
