The short answer
The interest rate excludes loan fees; APR is a broader borrowing-cost measure that includes points and certain other charges. Points exchange upfront money for a lower rate, but APR alone does not settle whether that exchange suits a short holding period.[1][2]
Read the rate and APR as different fields
The CFPB defines the interest rate as the annual cost of borrowing expressed as a percentage, without fees or other loan charges. APR includes the interest rate, points, mortgage broker fees and other borrowing charges, so it is usually higher—not necessarily always higher—than the interest rate.[1]
On a Loan Estimate, the interest rate appears on page 1 under Loan Terms, while APR appears on page 3 under Comparisons.[1] Copy both with their labels. Do not treat the gap between them as a fee in dollars, or multiply APR by the original balance to invent a monthly payment. This guide does not calculate APR: that would require the relevant fees, amounts and timing of the complete loan cash flows, rather than just a rate and one closing-cost figure.
One point is a price, not a promised rate cut
One discount point equals 1% of the loan amount, and fractional points are possible; these points are paid at closing.[2] For an invented $300,000 loan, one point costs $3,000 and 0.75 points costs $2,250. Neither statement says the interest rate falls by one percentage point or by 0.75 percentage points.
The CFPB says the actual rate reduction depends on the lender, loan type and mortgage market.[2] Ask for a zero-point version of the same loan as well as the points version. Also ask what a fee labelled points actually buys: the CFPB warns that some lenders use that word more broadly for percentage-based upfront fees, even though the points shown in the specified disclosure section must be connected to a discounted rate.[2]
Compare upfront dollars before doing recovery arithmetic
Consider two entirely hypothetical offers for the same $300,000 balance and term. Offer A has zero points and a $1,200 origination fee. Offer B has 0.75 points and a $1,000 origination fee. Assume all other costs are identical, no lender credits apply, and these fees are paid in cash rather than added to the loan.
The selected upfront charges are $1,200 for A and $2,250 + $1,000 = $3,250 for B. B therefore requires $2,050 more, not $2,250 more: its other fee is $200 lower. These are deliberately limited fee totals, not complete cash-to-close amounts. The $2,050 difference is an input for a comparison, not an APR, and it does not tell us the size of B’s rate reduction.
Use simple payback as a screen, not a verdict
Now assume, solely for this example, that B’s quoted principal-and-interest payment is $50 less each month. No interest rate is inferred from that assumed payment difference. Simple cash recovery is $2,050 ÷ $50 = 41 months. At 24 months, payment savings of $1,200 leave $850 of the extra upfront outlay unrecovered; at 60 months, $3,000 of savings exceed it by $950.
This screen ignores the time value of money, any difference in outstanding principal at payoff, and all charges excluded from the assumptions. It is not a full economic break-even calculation or a recommendation to buy points. The CFPB recommends asking for costs over several possible loan-holding periods when the timing of a move or refinance is uncertain.[2] Use the period you might keep this loan, not merely how long you might own a home.
Do not rank unlike loans by APR alone
The CFPB cautions against comparing fixed-rate and adjustable-rate mortgage APRs, and says an adjustable-rate loan’s APR does not reflect its maximum possible interest rate.[1] MyMortgageInsider likewise cautions that APR comparisons become problematic when loan terms differ.[5] Its editorial explanation is useful context, not a substitute for the actual disclosures.
Make a comparison sheet with the same loan amount, term, repayment structure and points or credits basis; request offers close together and record the quote date and any rate-lock conditions. The CFPB specifically recommends asking different lenders for the same amount of points or credits.[2] If those inputs cannot be aligned, retain the mismatch instead of announcing a winner from the smallest percentage.
Keep credits, cash needs and missing inputs visible
For rate-linked lender credits, the usual tradeoff runs opposite to points: less paid upfront in exchange for a higher interest rate. The CFPB also notes that some credits are unrelated to the interest rate, such as compensation for a problem.[2] Ask which kind appears in your offer rather than assuming every credit has the same price.
Before comparing, collect the Loan Estimates, itemized fees, points in both percent and dollars, credits, monthly principal-and-interest payments and expected holding periods. Keep other closing cash requirements separate from the selected fees used above. Ask the lender to explain any APR discrepancy and provide a holding-period comparison that includes payoff balances. Missing cash-flow inputs mean this worksheet cannot calculate a reliable APR or determine the cheapest loan for you.
