Mortgage Points in Plain English: The Break-Even Test Every Loan Officer Should Show
A lower rate is not automatically the better deal. This simple comparison shows borrowers when paying mortgage points may recover its upfront cost.
By Christopher Salem · 4 min read
A borrower sees two choices: a lower mortgage rate with points or a higher rate with less cash due at closing. The lower rate may look better, but the right comparison is how long it takes the monthly savings to recover the upfront cost.
That is the break-even test. It gives loan officers a clear way to explain the tradeoff without promising that one option is best for everyone.
Start with what a point actually costs
One discount point equals 1% of the loan amount. On a $400,000 loan, one point costs $4,000. The Consumer Financial Protection Bureau explains that points trade a higher upfront cost for a lower interest rate.
One point does not buy a fixed rate reduction. The change depends on the lender, loan program, borrower profile, lock period, and market pricing at that time. A point might produce a larger rate improvement on one rate sheet and a smaller one on another.
Lender credits reverse the tradeoff. The borrower accepts a higher rate and receives a credit that reduces closing costs. A credit is not free money. Its value must be compared with the higher monthly payment.
The simple break-even calculation
Use the extra upfront cost of the lower-rate option and divide it by the monthly principal-and-interest savings:
Break-even months = extra upfront cost ÷ monthly payment savings
Consider this hypothetical comparison for the same $400,000, 30-year fixed loan. It is an illustration, not a current rate quote.
| Option | Rate | Points | Monthly principal and interest |
|---|---|---|---|
| No points | 6.75% | $0 | $2,594.39 |
| Pay one point | 6.25% | $4,000 | $2,462.87 |
| Difference | 0.50 percentage point | $4,000 upfront | $131.52 less per month |
Dividing $4,000 by $131.52 produces a simple break-even period of about 30.4 months. If the borrower expects to sell, refinance, or pay off the loan before then, the monthly savings may not recover the point cost. Keeping the loan longer gives the lower payment more time to exceed the upfront expense.
The calculation is a starting point. It does not account for the value of keeping cash available, possible tax treatment, investment returns, or differences in other loan fees. Avoid giving tax advice and encourage the borrower to consult a qualified tax professional when that issue matters.
Compare complete offers, not isolated rates
The CFPB's Loan Estimate explainer shows discount points on page 2, Section A, and lender credits on page 2, Section J. Page 3 also includes comparison figures such as the annual percentage rate, or APR.
For a clean comparison, keep the loan amount, term, product, lock period, occupancy, and borrower profile the same. Then show the borrower the rate, point cost or lender credit, monthly principal and interest, total cash to close, and break-even period side by side. The CFPB also recommends comparing offers with the same amount of points or credits when shopping between lenders.
A borrower-friendly explanation
A loan officer can say: “The lower rate costs more today. We will divide that extra cost by the monthly savings to see how long you need to keep this loan before the lower rate comes out ahead.”
That keeps the conversation centered on the borrower's likely timeline and available cash. It also avoids the two common mistakes: selling the lowest rate without explaining its cost, or assuming points are never worthwhile.
