  6. Click Reset to clear all fields and start a new comparison.

Formula and Logic

This tool uses standard mortgage calculation formulas to compute accurate GFE comparisons:

  • Monthly Principal & Interest (P&I): Calculated using the formula: M = P * (r(1+r)^n) / ((1+r)^n - 1), where P is the loan amount, r is the monthly interest rate (annual rate / 12), and n is the total number of monthly payments (loan term in years * 12).
  • Total Interest Paid: (Monthly P&I * total number of payments) - loan amount.
  • Discount Points Cost: (Points paid / 100) * loan amount (1 point equals 1% of the loan amount).
  • Total Loan Cost: Total P&I + total closing fees + discount points cost.

All results are rounded to two decimal places for accuracy. Offers are automatically sorted by total loan cost to highlight the most affordable option.

Practical Notes

When comparing GFEs, keep these finance-specific tips in mind:

  • GFEs are required by law for most mortgage loans, but lenders may present fees differently—always verify that closing fees include all origination, appraisal, and title fees.
  • Lower interest rates may come with higher discount points: calculate whether paying points upfront saves money over the full loan term.
  • Loan term significantly impacts total cost: a 15-year term has higher monthly payments but far less total interest than a 30-year term.
  • GFEs are valid for 10 business days—use this tool to compare offers quickly before rates change.
  • Always check for prepayment penalties or adjustable-rate clauses not listed in the standard GFE fee section.

Why This Tool Is Useful

Comparing GFEs manually is time-consuming and prone to errors, especially when lenders use different fee structures or formatting. This tool eliminates guesswork by:

  • Standardizing calculations across all offers to ensure apples-to-apples comparisons.
  • Highlighting hidden costs like discount points and closing fees that may not be obvious at first glance.
  • Quantifying total savings between the cheapest and most expensive offer to help you negotiate better terms.
  • Providing a shareable, copyable summary you can use when discussing options with financial planners or family members.

Frequently Asked Questions

What is a Good Faith Estimate (GFE)?

A GFE is a standardized document lenders are required to provide within 3 days of a mortgage application. It lists all estimated loan terms, interest rates, and closing fees, so you can compare offers from different lenders without hidden surprises.

How many GFEs can I compare at once?

This tool supports up to 3 GFE comparisons at a time, which covers most homebuyers’ needs. If you have more than 3 offers, run multiple comparisons or prioritize the lenders with the most competitive initial rates.

Do discount points affect my monthly payment?

No, discount points are a one-time upfront cost that lowers your interest rate, which in turn lowers your monthly P&I payment. This tool automatically factors points into your total loan cost, so you can see if the upfront cost is worth the long-term savings.

Additional Guidance

For the most accurate results, use the final GFE provided by each lender, as initial estimates may change after underwriting. If you’re working with a financial planner, share the copied results from this tool to get personalized advice on which offer fits your long-term budget. Remember that the cheapest total loan cost may not always be the best option if it requires higher upfront closing costs you can’t afford—balance total savings with your current cash flow needs.
