The year after a Michigan home sells, its taxable value resets to half of the assessor's market value, so the seller's tax bill is not your tax bill. At the statewide median homestead rate that comes to about 1.5% of the price a year. Get the published rate for an address

Before you fall for a house

In Samantha's words

Numbers first

“Talking about documents and taxes isn't quite as exciting. Shocking, I know. But if you fall in love with a house before you understand your numbers, now we're doing everything backwards.”

The right number for your life

“Just because a number works on paper doesn't mean it's the right number for your life.”

How to use a mortgage calculator

What goes into the payment

Start with the price and the down payment. The rest is the loan, and the calculator works out principal and interest on it at the rate and term you pick. Then it adds what sits on top:

  • Property tax: a yearly amount or a percent of the price. In Michigan, plan with the bill after the sale: the year after a Michigan home sells, its taxable value resets to half of the assessor's market value, so the seller's tax bill is not your tax bill. Get the published rate for an address.
  • Homeowners insurance: a planning figure until you have an agent's quote.
  • HOA dues: the monthly amount, if the home has an association.
  • PMI: added on a conventional loan when the loan is more than 80% of the price, at the percent in the PMI field.

When you change the price, the down payment, tax and insurance keep the figure you typed, in dollars or as a percent, and the rest is worked out again.

Mortgage formula

M = P × r(1 + r)n ÷ ((1 + r)n − 1)

M is the monthly principal and interest, P the loan amount, r the monthly interest rate (the annual rate divided by 12) and n the number of monthly payments.

The calculator above works this out at the rate you pick, then adds tax, insurance, HOA dues and any PMI.

Payment terms

  • Principal and interest: The part of the payment that repays the loan and pays the interest on it. On a fixed-rate loan it stays the same every month.
  • Escrow: An account your servicer keeps for property tax and homeowners insurance. Part of each payment goes into it, and the servicer pays those bills from it.
  • Loan term: How many years the payments run. A shorter term has a higher payment and less total interest.
  • Annual percentage rate (APR): The interest rate plus certain charges, such as points and origination fees, expressed as a yearly rate so offers can be compared. The payment is worked out from the interest rate, not the APR.
  • Mortgage points: Prepaid interest to lower the rate; each point is 1% of the loan amount.
  • Amortization: Spreading the loan over its payments. Early payments are mostly interest, later ones mostly principal.

Common questions

If yours is not here, send Samantha your numbers from the calculator above.

What is included in my mortgage payment?

Principal and interest, plus the property tax and homeowners insurance most servicers collect through escrow, which together make PITI. A conventional loan with a smaller down payment usually adds PMI, and HOA dues, if the home has them, are usually paid to the association. The calculator shows each part on its own line.

The rate sets the principal and interest part of the payment, and the term sets how long you pay it. Pick a few rates in the calculator to see how far the payment moves. Your Loan Estimate is where the rate for a specific loan appears, and page 3 shows the total interest over the loan.

On a conventional loan, PMI usually applies when the loan is more than 80% of the home’s price or value, and the payment includes it until it comes off. FHA loans carry their own mortgage insurance whatever the down payment, and VA loans have no monthly mortgage insurance, with a one-time funding fee instead unless you are exempt. Change the down payment above to see what PMI adds.

Most servicers collect property tax through escrow, so the tax bill moves the payment. In Michigan the bill usually goes up the year after you buy, when the taxable value resets with the sale, so plan from what a new owner pays, not the seller’s bill. Our Michigan property tax calculator gives the published rate for an address.

A shorter term has a higher payment and much less total interest; a longer term has a lower payment and more interest over its life. Switch the term in the calculator to see the payment for each. If the shorter term’s payment stretches your budget, a longer term with extra principal when you can afford it is another way to pay it down sooner.

Not in this calculator, which shows the monthly payment. Our mortgage payoff calculator takes the balance, rate and payment from your statement and shows how much sooner extra payments, half payments every two weeks or a lump sum would pay the loan off.

This calculator includes principal and interest, property tax, homeowners insurance, HOA dues and PMI when the loan is more than 80% of the price. It leaves out lender fees and other closing costs, and its tax and insurance figures are planning numbers, not quotes. Your Loan Estimate is the document that shows a loan’s actual terms, and Samantha can go over one with you.

On Fannie Mae and Freddie Mac loans, the smallest credit score price adjustments start at 780, and pricing steps up at each lower tier. This calculator does not ask for a score: pick the rate from a quote or a Loan Estimate made for your file.

Enter the monthly dues in the HOA field and the calculator adds them to the payment. Dues are usually paid to the association rather than through escrow, but lenders still count them in the housing payment they use for your debt-to-income ratio.

On a conventional loan, PMI ends on its own when the balance is scheduled to reach 78% of the home’s original value, if your payments are current. You can ask your servicer to cancel it sooner, once the balance reaches 80% of the original value, with a good payment history. FHA loans follow their own rules. Our PMI removal calculator shows both dates from your own loan papers.
