Mortgage Calculator
- How is a monthly mortgage payment calculated?
- Principal and interest use standard amortization: loan amount, annual interest rate, and term in months determine the P&I portion. Add monthly property taxes, homeowners insurance, PMI (when down payment is under 20%), and HOA for the full housing payment.
- What is included in a monthly mortgage payment?
- A complete estimate includes principal, interest, property taxes, homeowners insurance, PMI when applicable, and HOA fees. P&I alone is not the full monthly cost — taxes and insurance are often escrowed by the lender.
- How do property taxes affect my monthly payment?
- Annual property taxes are divided by 12 and added to your payment when escrowed. Higher assessed value or tax rates increase the monthly total even if your loan amount stays the same.
- How does homeowners insurance affect my monthly payment?
- Annual insurance premium is spread across 12 months and included in most escrowed payments. Premiums vary by location, coverage, and deductible — enter your quote for an accurate total.
- When is PMI required on a mortgage?
- PMI is typically required on conventional loans with less than 20% down. It protects the lender, not the borrower, until you reach sufficient equity. FHA loans use MIP with different rules. See our PMI guide for cost ranges and removal.
- How does the interest rate change my mortgage payment?
- A higher rate increases principal and interest on the same loan amount; a lower rate reduces it. Even a quarter-point change can shift your monthly P&I by a meaningful amount over a 30-year term.
- How does a 15-year mortgage compare with a 30-year mortgage?
- A 15-year loan has higher monthly P&I but far less total interest. A 30-year loan lowers the required payment but costs more over time. Toggle both terms in this calculator or read our 15 vs 30 year guide for a worked example.
- What does paying extra on my mortgage do?
- Extra payments reduce principal faster, which lowers total interest and can shorten your payoff date. This calculator models optional extra monthly payments and shows interest saved.
- How much interest will I pay over the life of the loan?
- Total interest depends on loan amount, rate, term, and any extra payments. Results above show total interest for your inputs, plus a full amortization schedule breaking down each month’s principal and interest.
- What is PMI and when does it go away?
- Private Mortgage Insurance (PMI) protects the lender when you put less than 20% down on a conventional loan. PMI usually drops off once you reach 20% equity, either through payments or home appreciation. FHA loans use MIP with different rules.
- How much should I budget for closing costs?
- Closing costs typically range from 2% to 5% of the home purchase price. They include lender fees, appraisal, title insurance, prepaid taxes, and escrow setup. Our calculator estimates closing costs based on your home price and down payment.
- How do extra payments affect my mortgage?
- Extra payments go directly toward principal, reducing the balance faster. That lowers total interest paid and can shorten your loan term by years. Even small monthly extras can save tens of thousands over a 30-year loan.
- What down payment do I need to avoid PMI?
- A 20% down payment on a conventional loan typically avoids PMI. Some programs allow less — 3% to 5% for conventional, 3.5% for FHA — but you will pay mortgage insurance until you reach sufficient equity.
- Should I include HOA fees in my mortgage calculation?
- Absolutely. HOA fees are a recurring housing cost separate from your loan but part of your monthly budget. Omitting them can make a home appear more affordable than it really is.
Refinance Calculator
- When does refinancing make sense?
- Refinancing often makes sense when you can lower your interest rate enough that monthly savings recover closing costs within a reasonable time — typically a few years. It also helps if you want to shorten your loan term or remove PMI. Use our break-even chart to see if the numbers work for you.
- What is a refinance break-even point?
- The break-even point is how many months it takes for your monthly savings to equal the closing costs of the new loan. If you plan to stay in the home past break-even, refinancing may save money overall.
- Should I restart my loan term when I refinance?
- Extending to a new 30-year term lowers your payment but can increase total interest even at a lower rate. A shorter term raises the payment but saves more interest over time. Compare both monthly payment and total interest in our calculator.
- What closing costs should I include in a refinance estimate?
- Include lender origination fees, appraisal, title insurance, recording fees, and prepaid items like escrow setup. Costs typically run 2% to 5% of the loan amount, though no-closing-cost refinances roll fees into the rate or balance.
HELOC Calculator
- What is a HELOC?
- A Home Equity Line of Credit (HELOC) is a revolving line secured by your home. You can draw funds during a draw period, usually paying interest only, then repay principal and interest during the repayment period.
- How much can I borrow with a HELOC?
- Lenders typically allow a combined loan-to-value (CLTV) of 80% to 90% of home value, minus your existing mortgage balance. Our calculator uses your chosen CLTV cap to estimate maximum available credit.
- Why does my payment increase after the draw period?
- During the draw period, many HELOCs require interest-only payments. When repayment begins, you pay principal plus interest over the remaining term, which raises the monthly payment significantly.
- Are HELOC rates fixed or variable?
- Most HELOCs have variable rates tied to a benchmark like the prime rate. Some lenders offer fixed-rate conversion options. Enter your expected rate in the calculator to model payments.
