Mortgage payment calculator
Updated November 6, 2026. Runs entirely in your browser; nothing you type is sent anywhere.
Enter a home price, down payment (percent or dollars), annual rate, and term (15 and 30 years are common). You'll see an estimated principal+interest payment from the standard amortization formula, plus optional monthly property tax, insurance, and HOA fields for a rough PITI-style sketch. Those add-ons are clearly optional—not escrow truth, not a lender quote, and not financial advice.
Tip: if you only know annual tax or insurance, divide by 12 and enter the monthly figure. Add-ons are not escrow truth.
How to use the number
- Treat rate, term, tax, insurance, and HOA as planning assumptions. Real mortgages add PMI, fees, escrow cushions, and odd due-date rules.
- Compare a few rates and terms (for example 15 vs 30) rather than trusting one rosy scenario.
- If the payment is the hard part, free cash by renegotiating bills or unlocking pay—then re-run the math.
- When the hard part is the phone call—a bill, a landlord, a raise, or an offer—use a script, not improvisation under stress.
What to say when cash or pay is the bottleneck
Knowing the payment sketch is step one. Saying the next line on a bill, rent, raise, or offer call is where people freeze. The Bills Kit ($19) gives word-for-word lines for bill and landlord moments plus Call Mode. If pay is the lever that funds the payment, see the Offer Kit ($29). One-time purchase, 14-day refund on both.

How is principal and interest calculated?
The standard amortization sketch is M = P × r(1+r)^n / ((1+r)^n − 1), where P is the loan principal (home price minus down payment), r is the monthly rate (annual % ÷ 12 ÷ 100), and n is the number of months (years × 12). If the rate is zero, M is simply P ÷ n.
Are taxes, insurance, and HOA part of the loan payment?
No. Property tax, homeowners insurance, and HOA are optional add-ons on this page so you can sketch a rough PITI-style total. They are not escrow truth, not a lender quote, and not a substitute for your actual tax bill, insurance quote, or HOA dues.
Is this a mortgage offer or financial advice?
No. It is simple arithmetic on the numbers you type, plus a sample sentence you can adapt. It is not a quote, pre-approval, credit decision, tax advice, or a substitute for advice from a qualified professional or your lender.
Down payment percent vs dollars?
Enter either a down-payment percent of the home price or a dollar amount. If both are filled, the dollar amount wins. Principal is home price minus that down payment (floored at zero).
