Compare Two Fixed-Rate Mortgage Quotes

Tool methodology

How the fixed-rate quote comparator works

This workspace compares two fixed-rate amortizing scenarios on a common time horizon. It keeps borrowing cost, monthly cash outflow and remaining balance separate so one low headline payment does not hide a longer term or financed fees.

For each scenario, the model starts with the net principal, adds financed fees to the amortizing balance, solves the fixed monthly principal-and-interest payment, and builds a monthly schedule. Over the common comparison horizon it totals scheduled payments, tracks remaining debt and adds cash-paid fees once. Other monthly housing costs are reported as cash outflow but are not included in borrowing cost. Unequal net principal amounts trigger a comparability warning rather than pretending the quotes are like-for-like.

Starting amortizing balanceNet principal + financed fees

Financed fees affect the balance and interest but are not added again as cash fees.

Borrowing cost over horizonInterest paid + financed fees + cash-paid loan fees

Other housing costs remain outside borrowing cost.

Cash outflowScheduled loan payments + cash fees + entered other monthly housing costs

Shows a broader cash view while keeping categories distinct.

1Set the context

Enter the same net borrowing need for both scenarios when you want a like-for-like comparison.

2Apply the rules

Enter note rate, term, financed fees and cash-paid fees exactly as shown in the written terms you are reviewing.

3Review the output

Choose a horizon that matches how long you expect to keep the financing.

4Verify before acting

Review payment, balance, interest, fees and cash outflow separately before drawing a conclusion.

Best used for

Comparing two fixed-rate Loan Estimate scenarios
Seeing whether lower rate/high fees or higher rate/lower fees fits a holding period
Checking how a longer term changes monthly payment and remaining debt

What this tool does not answer

It is not a legal APR calculator.
It does not model ARM resets, HELOC draws, balloon payments, interest-only structures or prepayment penalties.
Different loan amounts are not directly comparable without adjusting the scenario.

Practical example

How to interpret the output

Example: if two quotes borrow the same net amount but one finances more fees, that quote begins with a larger amortizing balance. The tool counts the financed fee through the balance and borrowing-cost output once—not again as a cash-paid fee.

Enter the same net amount

Loan amount means the amount before newly financed fees. Enter financed charges separately so they increase the starting balance once. Cash-paid fees are counted once as an upfront cost. Different net loan amounts produce a warning.

Read the outputs separately

Borrowing cost includes modeled interest and cash-paid/financed fees. Other monthly expenses remain separate. Principal is part of cash outflow and reduces the outstanding balance; it is not counted as interest cost.

Scope and exclusions

The tool does not model ARM resets, interest-only periods, balloons, HELOC draws, reverse mortgages, changing mortgage insurance or prepayment penalties. It does not calculate a disclosure APR. Other monthly costs are assumed constant over the selected horizon, including after loan payoff.
