How this mortgage comparison calculator works

1. Enter each offer

Add a row per lender straight from page 1 and page 2 of the Loan Estimate: loan amount, term, rate, APR, points, lender credits, closing costs and mortgage insurance.

2. See the comparison

Every offer is lined up on monthly payment, upfront cost, break-even point and lifetime cost, so a low rate bought with heavy points can't hide.

3. Weight what matters

Slide the weighting toward cash at closing, lowest payment or lowest total cost and the ranking updates. Export the comparison as a CSV when you're done.

Comparing mortgage offers fairly means comparing the same loan shape — same lien position, same purpose, same term and roughly the same loan amount — on estimates dated within a few days of each other. This calculator enforces the lien and purpose match for you, and the guide on how to compare mortgage loan estimates walks through the rest line by line.
