Loan comparison

Two quotes, side by side — with the part most calculators leave out. A lower rate is usually bought with points, and the cheaper monthly payment is often the more expensive loan. This shows true cost and tells you how long a buy-down takes to pay for itself.

Loan A is $992/month cheaper to carry. They disagree — the cheaper monthly payment is not the cheaper loan here, usually because it runs longer.

Principal and interest only. Excludes property tax, homeowner's insurance, HOA dues, and mortgage insurance, so it is not a full monthly payment. Rates and points come from your lender's Loan Estimate — compare that document, not an advertised rate. Not financial advice.
