Interest-only loans build zero equity during the interest-only period. Your balance stays the same — you are only covering the cost of borrowing. Payments jump significantly when the loan converts to principal & interest.

Common mortgage questions

How do I calculate my monthly mortgage payment? +

Enter your home price, down payment, interest rate, and loan term above. Your monthly payment is calculated using the standard amortization formula and includes principal, interest, property taxes, homeowner's insurance, HOA fees, and PMI if your down payment is under 20%.

What is PMI and when do I need it? +

PMI (Private Mortgage Insurance) is required when your down payment is less than 20% of the home purchase price. It typically costs 0.5%-1% of the loan amount per year. Our calculator shows exactly when your PMI drops off and how much it adds to your total cost — something most calculators skip.

What is an amortization schedule? +

An amortization schedule shows how each monthly payment is split between principal and interest over the life of your loan. In the early years, most of your payment goes toward interest. Over time, more goes toward paying down your balance. Use the Amortization Table tab above to see your full schedule by year or month.

Should I choose a 15-year or 30-year mortgage? +

A 15-year mortgage has higher monthly payments but you pay significantly less total interest and build equity faster. A 30-year mortgage offers lower monthly payments and more cash flow flexibility. Use the loan term dropdown in the calculator to compare both scenarios and see the difference in total interest paid.

How much house can I afford? +

A common guideline is to keep your total monthly housing payment (including taxes and insurance) below 28% of your gross monthly income, and your total debt payments below 43%. For example, on a $90,000 annual income, aim for a monthly payment under $2,100. Use the calculator above to find a home price that fits your budget.
