Mortgage Questions & Answers
Helpful answers to common questions about mortgage payments, affordability, down payments, PMI, and comparing loan options.
How is a monthly mortgage payment estimated?
A basic mortgage payment estimate uses the loan amount, interest rate, and loan term to calculate principal and interest. Your actual monthly housing payment may also include property taxes, homeowners insurance, HOA dues, mortgage insurance, and other applicable costs.
How much house can I afford?
Home affordability depends on factors such as income, monthly debts, down payment, interest rate, taxes, insurance, and other housing costs. PreviewMyMortgage uses general housing and debt-to-income guidelines to provide an educational estimate, but actual lender standards may differ.
What is PMI on a mortgage?
Private mortgage insurance, or PMI, may apply to some conventional loans when the down payment is below certain levels. PMI requirements and costs vary by lender and loan program, and FHA loans use different mortgage insurance rules.
What is the difference between interest rate and APR?
The interest rate is the cost of borrowing the loan principal, while APR is designed to reflect the interest rate plus certain loan fees and costs. APR can be useful when comparing mortgage offers, but the exact fees included may vary by lender and loan structure.

About & calculation methods
PreviewMyMortgage offers free educational tools for exploring U.S. mortgage scenarios. We are not a lender, mortgage broker or financial advisor. These tools do not check credit, match you to lenders or determine approval.
Payment and comparison estimates assume a fixed interest rate and equal monthly payments for the full term, without extra payments. At 0% interest, principal is divided by the number of months. Total interest is total principal-and-interest payments minus the amount borrowed. Fees and closing costs are excluded; these are not APR comparisons.
Affordability uses the smaller of 28% of gross monthly income or 36% minus monthly debts, then subtracts the taxes, insurance, HOA and mortgage insurance you enter. The remaining payment budget estimates a loan amount, with your down payment added to estimate a home price. These are illustrative budgeting guidelines, not universal lending rules or a personal recommendation. Blank optional costs count as $0 and may overstate affordability.
Down payment percentage is down payment divided by home price; loan-to-value is the remaining loan divided by home price. The PMI preview is a general indication, not a premium quote. Conventional loans with less than 20% down commonly require PMI; other loan programs use different rules. Read the CFPB explanation of PMI.
Dollar inputs support amounts up to $1 trillion, interest rates from 0–100%, and whole-year terms from 1–50. These technical limits do not indicate available loan terms. Example rates are illustrations, not current offers. Results are rounded for display.
