The mortgage calculator helps estimate your monthly payment and other common housing costs. You can include property taxes, insurance, PMI, HOA fees, and other annual expenses. Results are educational estimates only—not financial or lending advice.
What is a mortgage?
A mortgage is a loan secured by real estate. The lender provides funds toward the purchase price; you repay principal plus interest over an agreed term (often 15 or 30 years in the U.S.). Part of your payment may also cover taxes and insurance through an escrow account. Until the loan is repaid, the lender typically holds a security interest in the property.
Key inputs
- Loan amount — Usually the purchase price minus your down payment. What you can borrow depends on income, credit, and lender guidelines.
- Down payment — Upfront cash toward the price. Larger down payments often improve terms; under 20% down, lenders may require PMI until you reach a target loan-to-value ratio.
- Loan term — How long you have to repay (e.g. 15, 20, or 30 years). Shorter terms often mean higher monthly payments but less total interest.
- Interest rate — The yearly cost of borrowing, often quoted as APR. This calculator models a fixed rate; adjustable-rate loans (ARMs) can change after an initial fixed period.
Recurring costs of homeownership
Beyond principal and interest, owners often pay property taxes, homeowners insurance, possible PMI, HOA fees, and ongoing maintenance. Taxes and insurance are often escrowed. These costs tend to rise over time with inflation.
- Property taxes — Levied locally; amounts vary widely by area and assessed value.
- Home insurance — Protects the dwelling (and often liability); premiums depend on coverage and risk factors.
- PMI — May apply when equity is below a threshold; cost depends on loan size, down payment, and credit.
- HOA fees — Common for condos and planned communities.
- Other costs — Utilities, maintenance, and repairs; many owners budget around 1% of home value per year for upkeep.
One-time costs (not in the calculator)
- Closing costs — Fees for title, recording, appraisal, and more; often several thousand dollars.
- Moving and upgrades — Moving, furniture, and optional renovations.
Paying off a mortgage faster
Common strategies include extra principal payments, biweekly payment plans, or refinancing to a shorter term.
Benefits: Less interest and an earlier payoff date. Tradeoffs: Prepayment penalties (if any), opportunity cost versus other investments, and less liquid cash on hand.
A brief note on U.S. mortgage history
Long-term, fixed-rate mortgages with smaller down payments became common after programs like the FHA and agencies such as Fannie Mae helped standardize lending and improve access to homeownership. Today, the 30-year fixed remains a popular product, though many borrowers also choose 15-year or other structures.
