Which Mortgage Offer Actually Costs Less?

Two lenders may advertise different interest rates, closing costs, discount points, and lender credits. The offer with the lowest interest rate is not necessarily the least expensive option.

Mortgage Maniac OS helps you compare two hypothetical or quoted mortgage scenarios using the numbers you enter.

The calculations run in your browser. This page does not request your name, email address, Social Security number, or credit report.

Step 1: Enter Your Homeownership Costs

These housing expenses apply equally to both mortgage scenarios.

Step 2: Compare Mortgage Offers

How to Understand Your Results

Monthly Mortgage Payment

The calculator combines principal and interest with your entered property taxes, insurance, mortgage insurance, and HOA fees.

Cash Needed at Closing

The calculator estimates the down payment plus entered lender and closing fees, discount points, and lender credits. It does not include prepaid taxes, initial escrow deposits, earnest money already paid, or other transaction-specific adjustments.

Five-Year Borrowing Costs

The report estimates interest paid, mortgage insurance, and entered financing fees over your selected comparison period. It separately shows principal paid and the remaining mortgage balance.

Break-Even Analysis

When one offer has higher upfront financing costs but lower monthly financing expenses, the engine estimates how long it may take for the monthly savings to recover the higher upfront expense.

Why Remaining Loan Balance Matters

A loan with a shorter term may have a higher monthly payment but pay down principal faster. Comparing payments alone can therefore produce misleading conclusions.

Important: This Is an Educational Comparison

The engine models fixed-rate, fully amortizing mortgages. It does not automatically apply FHA, VA, USDA, or conventional program rules.

Mortgage insurance is assumed to remain constant throughout the selected period. Real mortgage insurance may change or terminate, depending on the loan program and circumstances.

For a meaningful comparison, enter the same purchase price and ensure that fees are categorized consistently between the offers. Do not enter discount points twice.

The lower modeled cost is not necessarily the best mortgage for every borrower. Consider liquidity, affordability, loan eligibility, risk, and future plans.

Frequently Asked Questions

Can I compare two different mortgage lenders?

Yes. Enter the information from each lender's Loan Estimate to explore differences in monthly payments, points, fees, and borrowing costs.

Does a lower mortgage rate always save money?

No. A lower rate may require additional discount points or other upfront expenses. The expected length of time you keep the mortgage can influence whether those costs are recovered.

Can I compare a 15-year and 30-year mortgage?

Yes. The engine models different loan terms and displays the remaining balances at the end of the comparison period.

Are these current mortgage rates?

No. The example rates are hypothetical. Enter actual rates from lender quotes for a more relevant comparison.

Does this tool determine mortgage approval?

No. Mortgage approval requires a lender's verification and underwriting process.
