FREQUENTLY ASKED QUESTIONS
How is my monthly mortgage payment calculated?▼
Your monthly mortgage payment is calculated using the standard amortization formula: P × r × (1+r)^n / ((1+r)^n − 1), where P is your loan principal, r is your monthly interest rate (annual rate ÷ 12), and n is the total number of monthly payments. This calculator also accounts for your down payment.
What is the difference between 15-year and 30-year mortgages?▼
A 15-year mortgage offers higher monthly payments but significantly lower total interest paid over the loan life. A 30-year mortgage has lower monthly payments, making it more affordable month-to-month, but you'll pay much more in total interest. Use the comparison section above to see the numbers for your specific loan.
How much down payment do I need for a mortgage?▼
Down payment requirements vary by loan type. Conventional loans typically require 5–20%, while FHA loans may require as little as 3.5%. VA and USDA loans may offer 0% down options. This calculator lets you enter any down payment amount or percentage to see how it affects your monthly payment.
What is an amortization schedule?▼
An amortization schedule shows each loan payment broken down into principal and interest portions, plus the remaining balance over time. In early years, most of your payment goes toward interest. Over time, more goes toward reducing principal. Expand the table above to see your full yearly breakdown.
Are property taxes and insurance included in these calculations?▼
This calculator focuses on principal and interest only, which are the core components of your mortgage payment. Property taxes, homeowners insurance, and PMI vary by location and lender. Always consult a mortgage professional for a complete cost estimate.
