How is the monthly mortgage payment calculated?

The monthly payment is calculated using the loan amount (home price minus down payment), interest rate, and loan term. The formula accounts for both principal and interest, ensuring the loan is fully paid off by the end of the term. This calculator uses the standard amortization formula used by banks and lenders.

What is included in the monthly payment?

The calculated monthly payment includes only principal and interest (P&I). It does not include property taxes, homeowners insurance, HOA fees, or PMI (private mortgage insurance). Your actual monthly housing cost will be higher when these are included.

How much should I put down as a down payment?

Conventional wisdom suggests 20% down to avoid PMI and get better interest rates. However, many loans allow 3-10% down. A larger down payment reduces your loan amount, monthly payments, and total interest paid. Consider your savings, emergency fund, and other financial goals when deciding.

Should I choose a 15-year or 30-year mortgage?

A 15-year mortgage has higher monthly payments but you'll pay significantly less interest overall and build equity faster. A 30-year mortgage has lower monthly payments, providing more flexibility in your budget. Choose based on your income stability, other financial goals, and how long you plan to stay in the home.

How does the interest rate affect my payment?

The interest rate has a major impact on both monthly payments and total interest paid. Even a 0.5% difference can mean tens of thousands of dollars over a 30-year loan. Shop around with multiple lenders to get the best rate, and consider paying points to lower your rate if you plan to stay long-term.

What is an amortization schedule?

An amortization schedule shows the breakdown of each monthly payment into principal and interest, plus the remaining loan balance. Early payments are mostly interest, while later payments are mostly principal. This schedule helps you understand how your loan balance decreases over time.

Can I pay off my mortgage early?

Most mortgages allow early payoff without penalties, but check your loan terms. Making extra principal payments can significantly reduce total interest and shorten your loan term. Even small extra payments can save thousands in interest over time.

What is PMI and when is it required?

PMI (Private Mortgage Insurance) is typically required when your down payment is less than 20%. It protects the lender if you default. PMI usually costs 0.5-1% of the loan amount annually. Once you reach 20% equity, you can request PMI removal.

How accurate is this calculator?

This calculator provides accurate estimates for principal and interest payments using standard mortgage formulas. However, your actual payment may vary based on lender-specific terms, fees, and additional costs like taxes and insurance. Use this as a planning tool and consult with lenders for exact quotes.

Should I refinance my mortgage?

Consider refinancing if current rates are at least 0.5-1% lower than your rate, you plan to stay in the home long enough to recoup closing costs, or you want to change your loan term. Use this calculator to compare your current mortgage with potential refinance scenarios.
