Frequently Asked Questions

How is the monthly mortgage payment calculated? +
The monthly payment uses the standard amortization formula: M = P × [r(1+r)^n] ÷ [(1+r)^n − 1], where P is the loan principal, r is the monthly interest rate (annual rate ÷ 12), and n is the total number of payments (years × 12).
Does this include property taxes and insurance? +
No. This calculator computes the principal and interest (P&I) portion of your mortgage payment only. Your actual monthly housing cost will also include property taxes, homeowner's insurance, and possibly PMI (private mortgage insurance) if your down payment is less than 20%.
What is a good interest rate for a mortgage? +
Mortgage rates vary by country, lender, credit score, loan type, and market conditions. Historically, rates in the US have ranged from 3% to 8% for 30-year fixed mortgages. Use this calculator to compare different rate scenarios and see how even a 0.5% difference affects your monthly payment.
Should I choose a 15-year or 30-year mortgage? +
A 15-year mortgage has higher monthly payments but substantially less total interest paid. A 30-year mortgage has lower monthly payments and more flexibility, but you pay significantly more interest over the life of the loan. Use this calculator with both terms to compare the exact numbers for your situation.
How does the down payment affect my mortgage? +
A larger down payment reduces your loan principal, which lowers your monthly payment and the total interest you pay. Putting down 20% or more typically eliminates PMI requirements. Even increasing your down payment by a small amount can save thousands of dollars in interest over the life of the loan.
