Mortgage Calculator

Enter the home price, your down payment, and the interest rate to see an instant estimate of your monthly payment. Add annual property tax and insurance to get the true "all-in" payment most lenders quote.

• Down payment — subtract what you pay upfront from the price to get the loan amount.
• Interest rate — the annual rate your lender charges; 20-30% down often unlocks better rates.
• Tax & insurance — split annually across 12 months and added to the payment.
• Extra payment — see how paying a little more each month shortens your payoff.

Suppose you buy a home for $350,000 with 20% down ($70,000), so you finance $280,000 at 6.5% for 30 years:

• Principal & interest ≈ $1,770/month
• With ~$350/mo property tax and $140/mo insurance → about $2,260/month all-in
• Total interest over 30 years ≈ $357,000

Refinancing to 5.5% could cut the payment by roughly $140/month and save over $50,000 in interest.

• Monthly payment — the full amount due each month (PITI) with your inputs.
• Principal & interest — the loan portion only; taxes and insurance are separate line items.
• Payoff timeline — for the standard term; extra payments pull this forward.
• Total interest — the lifetime cost of the loan; lowering the rate or term reduces it.
