Mortgage Calculator With PMI and Taxes: How to Get Your Full Payment
A basic mortgage calculator only tells you part of the story. Our mortgage calculator gives you the principal and interest payment, but the amount that actually leaves your bank account each month usually includes property taxes, homeowners insurance, and in many cases private mortgage insurance (PMI). Here is how to add those pieces to the calculator's number so you get a realistic full payment.
What PITI means
Lenders describe the full monthly mortgage payment with the acronym PITI: principal, interest, taxes, and insurance. Principal and interest are fixed by your loan amount, rate, and term, and that is exactly what a standard mortgage calculator produces. Taxes and insurance vary by location and policy, so they get added on top separately.
Start with principal and interest
Enter your loan amount, interest rate, and term into the mortgage calculator to get your base payment. This uses the standard amortization formula, and it is the number every other line item gets added to.
Add property taxes
Property tax rates are set locally, so they range from under 0.5% of a home's assessed value per year in some states to over 2% in others. To estimate the monthly amount, multiply the home's value by the annual tax rate, then divide by 12. A $350,000 home taxed at 1.1% a year comes out to $3,850 annually, or about $321 a month. Most US lenders collect this monthly amount in an escrow account and pay the tax bill on your behalf.
Add homeowners insurance
Homeowners insurance is required by nearly every mortgage lender and typically runs somewhere between $1,000 and $2,500 a year for an average home, though cost varies a lot by state, home value, and coverage level. Divide the annual premium by 12 and add it to your running total the same way as property tax.
When PMI applies
Private mortgage insurance protects the lender, not you, and it typically applies whenever a conventional loan's down payment is under 20% of the home's price. PMI usually costs between 0.5% and 1.5% of the original loan amount per year, depending on your credit score and down payment size. On a $300,000 loan, that is $1,500 to $4,500 a year, or roughly $125 to $375 a month. PMI is not permanent: once your loan balance drops to 80% of the home's original value, you can request cancellation, and it is automatically removed at 78%.
Putting the full payment together
- Principal and interest: $2,100
- Property tax: $321
- Homeowners insurance: $110
- PMI: $180
- Total monthly payment: $2,711
That total, not the principal-and-interest figure alone, is the number to compare against your budget. Run your own loan amount, rate, and term through the mortgage calculator first, then add your local tax rate, an insurance quote, and PMI if it applies.
Ways to lower the total
Putting down at least 20% eliminates PMI entirely. Shopping insurance quotes from a few carriers can meaningfully lower that line item too, since premiums for the same coverage vary by insurer. Property tax is largely fixed by location, though some homeowners successfully appeal an assessment they believe is too high.
Frequently asked questions
Does the mortgage calculator include PMI and taxes?
No. It calculates principal and interest only. Add your local property tax rate, a homeowners insurance estimate, and PMI if your down payment is under 20% to get your full monthly payment.
How much does PMI typically cost?
PMI usually runs between 0.5% and 1.5% of the original loan amount per year, depending on credit score and down payment size, and it can be removed once your loan balance reaches 80% of the home's original value.
How do I estimate my property tax for a mortgage payment?
Multiply your home's assessed value by your local annual tax rate, then divide by 12 for the monthly amount. Rates vary widely by state and county, so check your local assessor's rate for an accurate figure.
