How It Works
A mortgage is a loan used to purchase a home, with the property serving as collateral. Your monthly payment consists of principal and interest, plus often property taxes, homeowners insurance, and PMI if your down payment is under 20%.
Our calculator focuses on the principal and interest portion of your payment. A larger down payment reduces your loan amount and can eliminate the need for private mortgage insurance.
Understanding mortgage costs helps you set realistic expectations for homeownership and ensures you choose a loan that fits your budget.
The Formula
M = P × [r(1+r)^n] / [(1+r)^n - 1]M = Monthly payment, P = Loan principal (home price minus down payment), r = Monthly interest rate, n = Total months (years × 12)
Example
Scenario: You buy a $350,000 home with a $70,000 down payment (20%) and finance $280,000 at 6.5% for 30 years.
Result: Your monthly payment would be $1,770. Over 30 years, you'd pay $637,234 total, including $357,234 in interest.
Insight: A 20% down payment saves you from paying PMI, which typically costs 0.5-1% of the loan amount annually.
