Direct answer
Discount points break even only if cumulative rate-related savings exceed their upfront and financing cost before the mortgage is sold, refinanced, or repaid.
What this calculation tells you
The estimate identifies when one entered mortgage-pricing option overtakes another in cumulative cash flow.
It cannot predict how long the loan will be held, future refinance opportunities, tax treatment, or lender pricing.
Where it is used
Home buyers
Compare rate-and-fee options.
Refinancing
Test whether points can be recovered.
Mortgage advice
Show holding-period sensitivity.
Household planning
Assess upfront cash alternatives.
When this guide helps
- A lender quotes several point options.
- The household may move soon.
- Points would be financed.
- A refinance is plausible.
Compare complete offers
Use the same loan amount and term while including points, lender credits, other fees, and any effect of financing costs into principal.
Choose the realistic horizon
Savings after a sale, payoff, or refinance are not realized, so test the earliest plausible exit as well as a longer case.
Consider liquidity and uncertainty
Cash used for points is unavailable for reserves or other goals, and future rates or plans can change before the calculated break-even.
Common mistakes
Before relying on mortgage points: pay now for a lower rate?, test the stated assumptions and keep its decision boundary visible.
- Dividing points by first-month savings when savings change.
- Ignoring financed-point interest.
- Assuming the mortgage will be held to term.
Worked case: one point
Loan amount is 300,000; one point costs 1%; the lower-rate payment saves an entered 45 monthly.
Point cost=3,000. Simple break-even=3,000/45=66.67 months.
The payment-only break-even occurs around month 67.
Taxes, balance differences and opportunity cost are omitted from this simple screen.

Worked case: sell in four years
Expected holding period is 48 months.
Entered payment saving=48x45=2,160, which is 840 below the 3,000 point cost.
The point is not recovered by month 48 under the simple payment comparison.
Use actual loan schedules and exit balances for the final analysis.

mortgage points: compare assumptions, not just answers
Points can have different tax and disclosure treatment. Verify the quote, rate lock and jurisdiction rather than relying on a generic label.
| Scenario | Changed assumption | Result |
|---|---|---|
| Hold 67+ months | 45/month | Simple recovery |
| Exit month 48 | 2,160 saving | 840 unrecovered |

Practical questions
Frequently asked questions
Are points the same as all lender fees?
No. Points specifically relate to pricing in many markets; other origination and closing charges should be identified separately.
Do points always lower the rate?
Use the actual official quote; terminology and treatment vary by product and jurisdiction.
Can points reduce tax?
Tax treatment is jurisdiction- and circumstance-specific and requires current authoritative guidance.
