Mortgage Comparison Calculator

Use this mortgage comparison calculator to compare two mortgage offers side by side. Enter the home price, down payment, interest rate, loan term, closing costs, and upfront fees for each offer to estimate monthly principal and interest payments, total interest, and overall borrowing costs. Compare the results to understand how different loan terms and fees can affect your budget.

Enter the home price and down payment for each mortgage option. The calculator estimates the loan amount after subtracting the down payment, then calculates the monthly principal and interest payment using the interest rate and repayment term you select.

Compare the monthly payments to see which option may fit your budget more comfortably. A larger down payment generally reduces the amount borrowed, while a lower interest rate can reduce borrowing costs. You can also use the down payment calculator to estimate how different upfront contributions affect your loan.

Even a small difference in mortgage interest rates can affect monthly payments and total interest over time. The loan term matters, too: a shorter term usually means higher monthly payments but less total interest, while a longer term generally spreads repayment over more months.

Enter the rate and term for both offers to compare their estimated payments and interest costs. For a more informed decision, compare similar loan types and repayment periods whenever possible. The 30-year vs. 15-year mortgage comparison can help you understand the trade-off between payment size and repayment time.

A mortgage offer should not be judged by its interest rate alone. Closing costs and upfront charges can change the total cost of borrowing, even when one lender offers a lower rate.

Enter the estimated closing costs and upfront fees for each mortgage option. The calculator adds these amounts to the estimated interest cost to compare total borrowing costs over each loan’s full term. It does not include every possible expense, so check each lender’s Loan Estimate for a complete breakdown of charges.

The calculator estimates the total interest paid over the selected loan term and combines it with the entered closing costs and upfront fees. This helps you see whether a lower monthly payment also corresponds to a lower estimated cost over the full repayment period.

The total-cost comparison assumes you keep each mortgage for its entire term. If the offers have different loan terms, the comparison covers different time periods and may not represent the cost of selling or refinancing earlier. To evaluate the offers more thoroughly, review the APR vs. interest rate guide and compare the annual percentage rate, lender fees, and repayment conditions.

Use the side-by-side results to weigh monthly affordability against long-term interest and upfront costs. The lowest monthly payment may not be the least expensive option overall, and paying more upfront may not be worthwhile if you expect to move or refinance soon.

This calculator estimates principal and interest, total interest, and selected upfront costs. It does not include property taxes, homeowners insurance, mortgage insurance, HOA fees, or other ongoing housing expenses. Before choosing an offer, confirm the final loan terms and compare the complete costs using each lender’s official disclosures.
