Rate vs. APR: Reading a Mortgage Quote Like a Skeptic
Two lenders quote the same rate; the APRs differ by a third of a point — that gap is fees, expressed as interest. What APR includes, where the measure breaks down, and how to compare offers when you will not keep the loan 30 years.

Every mortgage advertisement shows two percentages: the rate, and a slightly larger APR. The gap between them is the advertisement's most informative pixel — it is the lender's fees, converted into interest-rate form — and reading it correctly is the fastest way to spot an expensive loan wearing a cheap rate.
What each number is
The note rate is what your monthly payment is computed from — interest on the balance, nothing else. The APR re-solves the loan as if the finance charges — origination fees, points, and certain closing costs — were additional interest spread over the full term. Same payment stream, plus the fees, expressed as a single yearly percentage. A 6.5% rate with an 6.9% APR is carrying meaningful fees; a 6.5% rate with a 6.55% APR is nearly fee-free. Between two quotes at the same rate, the lower APR is the cheaper loan — that comparison is exactly what the number was mandated for.
Where APR misleads
- It assumes you keep the loan to maturity. Fees in the APR are spread over 30 years — but the median mortgage lives far shorter before a sale or refinance. Front-loaded fees hurt a 6-year borrower much more than the 30-year APR admits. High-fee/low-rate loans look better in APR terms than they perform for short holders.
- Lenders differ on inclusions. The regulation leaves edge cases, so two APRs are not always computed from identical fee sets — the Loan Estimate's line items are the ground truth.
- ARM APRs are projections built on index assumptions that will not survive contact with the future.
The skeptic's method
Collect Loan Estimates from two or three lenders within a short window (rates move daily). Compare total lender fees directly from the forms, and compute a personal break-even: the extra fees of the lower-rate offer divided by its monthly saving, in months — then judge against how long you honestly expect to hold this loan. The APR calculator shows how any fee load converts to an effective rate over the horizon you choose — your APR, not the 30-year fiction — and the loan comparison tool puts the finalists side by side.
