Mortgage Points Break-Even: How Long Must You Keep the Loan?
In this guide
A mortgage points break even analysis asks whether more cash at closing is recovered by a lower monthly payment. The CFPB explains that one point equals 1% of the loan amount, but there is no fixed rate reduction per point. The value depends on the lender, loan, and market.
The practical question is not whether the quoted rate is lower. It is whether you will keep the loan long enough for monthly payment savings to recover the upfront cost.
What one mortgage point costs
One point on a $400,000 mortgage costs $4,000. Half a point costs $2,000, and 1.375 points costs $5,500. Points appear as an upfront charge and should be connected to a discounted interest rate on the Loan Estimate and Closing Disclosure.
Do not assume one point always lowers the rate by 0.25 percentage point. A lender may offer a larger or smaller reduction depending on pricing that day. Compare actual offers with the same loan type, term, lock period, and features.
A concrete break-even example
Suppose a borrower compares two 30-year fixed mortgages for $400,000. Offer A has a 6.5% rate and no points. Offer B has a 6.125% rate and charges one point, or $4,000. Principal and interest are about $2,528 per month without points and $2,430 with points. The monthly savings are approximately $98.
Divide $4,000 by $98. The simple cash break-even is about 41 months, or 3.4 years. Before that month, the cumulative payment savings are smaller than the point cost. After that month, the borrower begins to have positive nominal savings, assuming the loan is still outstanding and the comparison does not change.
Net savings by holding period
Holding period makes the tradeoff visible. After three years, 36 months of savings total about $3,522, still roughly $478 short of the point cost. After five years, payment savings total about $5,870, producing approximately $1,870 of nominal net savings. After seven years, net savings are about $4,218. After ten years, they are roughly $7,740.
These figures do not discount future savings to present value, model investment opportunity cost, or include tax effects. They are a clear first-pass comparison. If the break-even is close to your expected exit date, a more complete analysis may reverse the conclusion.
Use the expected life of the loan
The relevant holding period is how long you expect to keep this mortgage, not just the house. Selling ends the loan, but so does refinancing. A borrower can remain in the property for 15 years and refinance after two. In that case, points bought on the first loan had only two years to generate savings.
Consider an early, expected, and long holding period. If points lose money in the early case and only barely win in the expected case, the zero-point offer may preserve flexibility. If you are highly likely to keep the loan for a decade and have adequate cash reserves, points may be more attractive.
Compare incremental costs, not every closing line
If both offers have the same appraisal, title, recording, and prepaid charges, those items do not decide whether to buy points. Compare the costs that change between offers. If the lower-rate offer also has an additional origination fee, add it to the point cost. If it has a lender credit elsewhere, subtract the relevant credit only after confirming the complete pricing.
Keep escrow deposits and prepaids separate. They affect cash needed at closing but may not represent a permanent cost difference. Ask the lender to explain any line that changes between Loan Estimates.
What about opportunity cost?
Cash used for points cannot simultaneously remain in emergency savings, reduce high-rate debt, or be invested. If paying points would leave you without a safe cash buffer, the rate reduction may not justify the liquidity risk. If the alternative is investing, investment returns are uncertain while mortgage payment savings are contractual as long as the loan remains in place.
A more conservative test is to require break-even comfortably before the expected holding period. That margin compensates for uncertainty and the value of keeping cash available.
Points versus a larger down payment
Both require cash but solve different problems. A larger down payment reduces the balance and may affect loan-to-value, pricing, or mortgage insurance. Points do not reduce principal; they purchase a lower rate. Ask the lender to quote both uses of the same cash. For some borrowers, reaching a loan-to-value threshold can be more valuable than buying points.
Points versus lender credits
Lender credits work in the opposite direction. You accept a higher rate and receive money toward closing costs. Credits may suit a borrower expecting to keep the loan briefly or needing to preserve cash. Points may suit a borrower with a long holding period. A middle or zero-point option often provides flexibility when the timeline is uncertain.
A disciplined comparison process
- Get same-day written offers for the same loan type and term.
- Confirm the rate, points, lender credits, and lock period.
- Calculate each principal-and-interest payment.
- Add every incremental upfront cost tied to the lower-rate option.
- Divide incremental cost by monthly savings.
- Compare break-even with early, expected, and long holding periods.
- Check whether paying points weakens your emergency reserve.
Bottom line
Mortgage points are not automatically good or bad. They are a holding-period decision. In the example, one point costs $4,000 and saves about $98 per month, producing a break-even near 41 months. Keeping the loan for two years loses money; keeping it for ten years produces meaningful nominal savings.

Holding-period checkpoint
On a $400,000, 30-year loan, paying $4,000 to move from 6.5% to 6.125% saves about $98 per month. Break-even is about 41 months; estimated nominal net savings are about $1,870 after five years and $7,740 after ten.
