A $450,000 home with 20% down finances $360,000 and costs $2,287 a month in principal and interest at 6.55% over 30 years — about $2,850 a month once property tax and insurance are included.
Rate is the Freddie Mac 30-year average as of 2026-07-16; the all-in figure assumes a 1.1% property-tax rate and $1,800/yr insurance. Your own payment depends on your rate, local tax rate, and insurance quote.
How your mortgage payment is calculated
A fixed-rate payment blends principal (the balance you pay down) and interest (the cost of borrowing) into one level amount using the standard amortization formula — the split shifts over time, but the payment stays the same. Early on, most of it goes to interest; the chart above shows exactly when the crossover happens.
P is the loan amount, r the monthly rate (annual ÷ 12), and n the number of payments (years × 12). The full figure adds property tax, insurance, PMI, and HOA on top — together, your PITI. Under 20% down, PMI is added automatically until you reach 20% equity.
Common questions
How much should my down payment be?
What's included in PITI?
Does a shorter term save money?
When does PMI go away?
How we calculate this
Payments use the standard fixed-rate amortization formula; the chart is computed month by month. PMI is estimated at 0.75% of the loan annually below 20% down. Figures are planning estimates, not a loan offer — this is not financial advice.
