How to use this calculator
Four quick steps. Everything recalculates the moment you change a number, so there's no submit button to hunt for.
Set price & down payment
Enter the home price and your down payment. Switch between a dollar amount and a percent with one tap.
Choose a term & rate
Pick 30, 20, 15, or 10 years. The rate starts at this week's average. Change it if you've been quoted one.
Fine-tune the details
Open the advanced panels for property tax, insurance, PMI, HOA dues, and extra payments.
Read your results
See the PITI split, total interest, payoff date, and a full schedule you can download or print.
What's included in your payment
A mortgage payment is more than principal and interest. Here's every piece, with the default assumption we use and where it comes from.
Principal
The slice that pays down what you borrowed. It starts small and grows every month as the balance falls.
Interest
The cost of the loan, charged on your remaining balance. Early payments are mostly interest, and that flips over time.
Property tax
Set to 1.1% of the home price a year by default, the rough US average. Rates vary widely by county, so check yours.
Homeowners insurance
Defaulted to about $1,800 a year. Coastal, wildfire, and older homes tend to cost more to insure.
PMI
Added only when your down payment is under 20%, at 0.55% a year by default. It drops off automatically at 20% equity.
HOA dues
Monthly dues for condos and planned communities. Off by default. Add yours if the property has them.
What the math looks like
Take a $420,000 home with 20% down at this week's 6.49% rate on a 30-year loan.
You'd repay the $336,000 you borrowed plus about $427,754 in interest. That's why the loan term and rate matter so much, and why even small extra payments pay off. Shorten the term to 15 years in the calculator and watch the total interest fall by more than half.
Key terms, defined
- Principal
- The amount you borrow. Each payment chips away at it, and the shrinking balance is what builds your equity.
- Interest
- The lender's charge for the loan, calculated on the remaining balance. Early on it's the biggest slice of your payment.
- PITI
- Principal, Interest, Taxes, and Insurance. The four parts that make up a typical monthly house payment.
- Escrow
- An account your lender uses to collect and pay property tax and insurance for you, spread across the year.
- PMI
- Private mortgage insurance, added when your down payment is under 20%. It falls off once you reach 20% equity.
- Amortization
- The schedule that shows how each payment splits between principal and interest until the balance hits zero.
- LTV
- Loan-to-value: the loan divided by the home's value. Lower LTV means more equity and, past 80%, no PMI.
- Escrow vs. rate
- Your interest rate sets principal and interest only. Taxes, insurance, and dues are separate line items on top.
