Mortgage Calculator
- How is a monthly mortgage payment calculated?
- Your monthly payment typically includes principal and interest (P&I), property taxes, homeowners insurance, PMI if your down payment is under 20%, and HOA fees if applicable. Principal and interest follow a standard amortization formula based on loan amount, interest rate, and term length.
- 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.
- What is the difference between a 15-year and 30-year mortgage?
- A 15-year mortgage has higher monthly payments but far less total interest paid over the life of the loan. A 30-year mortgage spreads payments over a longer period, lowering the monthly cost but increasing total interest. Use our comparison tool to see the tradeoff for your numbers.
- 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.
- Do property taxes and insurance affect my monthly payment?
- Yes. Most lenders escrow property taxes and homeowners insurance, adding them to your monthly payment. Even if you pay them separately, they are part of your true housing cost and should be included when comparing homes or budgets.
- 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.
