For a $320,000 loan at 7% annual interest for 30 years: Monthly P&I = $320,000 × [0.005833 × (1.005833)^360] / [(1.005833)^360 − 1] = $2,129/month
The principal is the amount you borrowed. The interest is the lender's charge for lending that money. In the early years of a 30-year mortgage, most of your payment goes toward interest — often 80–90% in year one. By year 25, the ratio flips and most goes to principal. This is why extra payments in early years have such a powerful impact.
Property taxes are collected by your local government and are typically escrowed — collected monthly by your lender and paid annually. Tax rates vary significantly by location: from under 0.3% in Hawaii to over 2.2% in New Jersey. On a $400,000 home in a mid-range area, expect $3,000–$6,000/year in property taxes.
Your lender requires homeowners insurance to protect the collateral. Average cost is $1,200–$2,500/year depending on home value, location, coverage amount, and claims history. Some high-risk areas (flood zones, hurricane zones) require additional coverage through FEMA's National Flood Insurance Program.
PMI protects the lender if you default, and is required when your down payment is less than 20%. It typically costs 0.5%–1.5% of the loan amount annually ($100–$250/month on a $200,000 loan). PMI is not permanent — you can request cancellation once your equity reaches 20% (78% LTV triggers automatic cancellation under federal law). Making extra principal payments can accelerate PMI removal significantly.
The choice between a 15-year and 30-year mortgage is one of the most important financial decisions you'll make. Here's a real comparison on a $350,000 loan:
The 30-year mortgage provides more monthly cash flow flexibility. The 15-year builds equity dramatically faster and saves hundreds of thousands in interest. A hybrid approach — take a 30-year mortgage but make additional principal payments equivalent to the 15-year payment — gives flexibility while reducing the payoff period.
Your down payment has a multi-layered impact on your mortgage:
Amortization front-loads interest payments. On a $300,000 mortgage at 7% for 30 years, your first payment of $1,996 breaks down as: $1,750 interest and only $246 principal. By year 15, it's more balanced. By year 25, you're paying mostly principal.
This structure means an extra $100/month payment in year 1 saves far more in future interest than the same payment in year 20. Even one extra payment per year can cut 4–6 years off a 30-year mortgage and save $50,000–$80,000 in interest.
Refinancing replaces your existing mortgage with a new loan, ideally at a lower rate. The general rule is that refinancing makes sense when you can lower your rate by at least 0.75–1%, you plan to stay in the home long enough to recoup closing costs (typically 2–5 years), and your credit has improved since the original loan. Use the calculator to compare your current payment vs. a refinanced payment to determine your monthly savings and break-even timeline.

Your mortgage is likely the largest financial commitment of your life. Understanding the true cost — not just the monthly payment — is critical. A $300,000 30-year mortgage at 7% costs $418,527 in total interest. Knowing this helps you make better decisions about loan term, down payment size, and whether to refinance or make extra payments.
Down payment: A 20% down payment eliminates PMI (Private Mortgage Insurance), saving $100–300/month. Loan term: 15-year mortgages have higher monthly payments but save massively on total interest. Credit score: A 760+ credit score vs. 620 score can mean 1–2% lower interest rate — saving $50,000+ over 30 years. Interest rate type: Fixed rate locks in your payment forever; ARM (Adjustable Rate) starts lower but can increase.
