Mortgage Discount Points: Should You Buy Down Your Rate?
Discount points let you pay upfront cash to lower your mortgage rate. One point costs 1% of the loan amount and typically reduces the rate by about 0.25 percentage point, though the exact trade varies by lender and market. Buying points can save real money over time — but only if you keep the loan long enough to recover the cost. This guide shows you how to decide.
How Points Translate to Rate
Each point is 1% of the loan. On a $400,000 loan, one point costs $4,000. The rate reduction per point is not fixed; in some markets a point buys 0.125%, in others 0.25% or more. Your Loan Estimate shows the cost and the resulting rate side by side with a zero-point option.
The Break-Even Math
Example: $400,000 Loan
0 points: 6.5% → $2,528/mo
1 point ($4,000): 6.25% → $2,462/mo — saving $66/mo
Break-even: $4,000 ÷ $66 ≈ 61 months (~5 years)
If you stay longer than five years, the points start saving you money; sell sooner and you lose the upfront cost.
When Buying Points Makes Sense
- You plan to stay in the home past the break-even point.
- You have cash to spare beyond the down payment and reserves.
- Rates are high and you want to lock a lower effective rate now.
- You need a slightly lower payment to qualify (buying points lowers the payment DTI).
When to Skip Points
If you expect to move or refinance within a few years, the upfront cost rarely pays back. Also, if your cash is better used for a larger down payment (to drop PMI) or an emergency fund, points are a low priority. Opportunity cost matters.
Points and Taxes
For a purchase, discount points are generally deductible in the year paid as prepaid interest, subject to limits. For a refinance, they are usually deducted ratably over the loan term. A tax preparer can confirm your specific treatment.
Negative Points and Lender Credits
The inverse exists: a lender credit (negative points) raises your rate in exchange for cash toward closing costs. It eases upfront cash needs but costs more over time. Points and credits are opposite levers on the same trade-off.
Comparing Offers
Always get multiple Loan Estimates and compare at the same rate, not the same points. One lender may show a low rate with points while another offers that rate with fewer points. Normalize to "cost for the rate you want" before choosing.
Points on a Refinance
Points work the same on a refinance as a purchase: you pay upfront to lower the new rate. The key question is break-even against how long you will keep the refinanced loan. If you refinanced to escape a high rate and plan to stay many years, points can deepen the saving; if you expect to move soon, a no-point refinance preserves flexibility. Model the refinance savings both with and without points before signing.
The APR Reveals the Trade
The APR on your Loan Estimate blends the rate with upfront costs, including points. A loan with points shows a lower note rate but a higher APR than a no-point loan at the same rate would; comparing APRs at the same rate tells you the true cost of the points. Use APR as the honesty check on whether the points are worth buying for your time horizon.
Points vs a Larger Down Payment
If you have extra cash, choose between buying points and increasing your down payment. More down payment lowers the loan amount (and may drop PMI), saving every month and building equity; points only lower the rate. For a borrower close to the 20% PMI threshold, the down-payment bump often beats points because it removes insurance. Run both scenarios with a calculator rather than guessing.
Tax Timing
On a purchase, points are generally deductible in the year paid; on a refinance, they are spread over the loan term. If you close near year-end, the purchase deduction lands in that tax year, which can matter for bracket planning. A tax preparer can confirm current treatment, since the rules have shifted in some years. Do not let a deduction alone drive the decision — the rate saving is the main event.
Worked Example: $250,000
Zero points at 6.75% costs $1,622/mo. One point ($2,500) at 6.5% costs $1,580/mo — a $42 monthly saving, break-even near 60 months. Two points ($5,000) at 6.25% saves $83/mo, break-even near 60 months too but ties up more cash. If you stay ten years, two points saves about $5,000 net; if you move in three, you lose roughly $2,500. The longer you stay, the more points pay.
Negotiating Points Away
Points are not always fixed; some lenders waive or reduce them to win your business, especially with strong credit. Ask each lender for their best no-point rate and their best rate with one point, then decide. Competition among lenders is your leverage, so get at least three quotes and use them against each other.
Points and the Break-Even on a Refinance
On a refinance, the break-even math compares the upfront points to the monthly saving versus your current loan, not versus a zero-point new loan. If your old rate is 8% and the new zero-point rate is 6.5%, you already save a lot; adding points to reach 6.25% may take many years to pay back, by which time you might refinance again. For refinances, the case for points is weaker unless you are certain you will keep the loan long. Let the break-even drive the decision, not the sales pitch.
How Lenders Quote Points
A lender's rate sheet lists several rate/point combinations: you can take a higher rate with a lender credit (negative points) or pay points for a lower rate. The par rate is the one with neither. Sales pressure sometimes pushes points, but they are optional. Tell the lender your planned stay and ask for the option that minimizes total cost over that window; a good loan officer shows the full menu rather than steering to one choice.
Points and the Monthly DTI
Because buying points lowers your rate, it lowers your monthly payment, which can help you qualify under DTI limits when you are close. Some buyers buy a fraction of a point purely to cross the qualifying threshold, not for long-term saving. If you are on the edge of approval, even a small rate reduction from points can be the difference between yes and no — a strategic use beyond pure investment return.
Discount Points vs Temporary Buydowns
A temporary buydown (like a 2-1 buydown) pays to lower your rate only for the first two years, then it returns to the note rate. Points lower the rate for the whole loan. Builders and sellers sometimes offer temporary buydowns to make payments look affordable early. Know whether you are buying a permanent reduction (points) or a short intro discount (buydown); they solve different problems and cost differently.
State Tax Notes on Points
The deductibility of points has changed in different tax years; currently, for a purchase, discount points are generally deductible as mortgage interest in the year paid, while refinance points are amortized. High-income buyers subject to limits should coordinate with a preparer. Do not let a potential deduction justify points you would not otherwise buy — the rate saving must stand on its own; the tax treatment is a secondary bonus.
A Practical Decision Rule
Use this rule: estimate your break-even in months by dividing the point cost by the monthly saving; if you will keep the loan longer than that, points likely pay; if shorter, skip them. Add a margin for uncertainty, because life rarely follows the plan exactly. This single calculation resolves most points questions better than any generic advice, and it keeps you from overpaying for a rate you will not enjoy long enough.
Points on a Second Home
Second-home and investment loans carry higher rates and often stricter point pricing than primary residences. Buying points on a rental may still pay if you hold the loan long, but the higher base rate and shorter intended hold usually argue against it. Model the break-even against your planned ownership; for a property you will flip or refinance soon, points on an investment loan rarely pay back. Reserve points for long-held, primary-residence loans where the math is cleanest.
The Par Rate Concept
The par rate is the interest rate at which the lender charges no points and gives no credit — the neutral price. Below par, you pay points; above par, you receive a credit. Knowing par lets you compare offers honestly: a lender advertising a very low rate is likely below par (you pay), while one with a credit is above par. Always anchor comparisons to par so you see the true trade between rate and upfront cost.
Points and a Seller-Paid Buydown
Instead of the borrower buying points, a seller or builder may buy down the rate as a concession, effectively paying points on your behalf. This lowers your payment without touching your cash and can be negotiated into the price. A seller-paid buydown is pure benefit to you if you stay; just confirm whether it is a permanent rate reduction (points) or a temporary buydown (returns to note rate), because the two solve different time horizons.
Points vs Paying Down the Loan
With extra cash, choosing between points and a larger down payment depends on PMI. More down payment lowers the loan and may remove PMI, saving every month and building equity; points only lower the rate. For a buyer near the 20% line, the down-payment bump usually beats points because it kills insurance. Run both scenarios with a calculator so the cash is deployed where it saves the most over your planned stay.
Points and the Break-Even Revisited
A quick way to sanity-check points: divide the cost by the monthly saving to get break-even months, then compare that to how long you will keep the loan. If break-even is 60 months and you will stay 10 years, points likely pay; if you will move in three years, skip them. This simple division resolves most points questions better than any generic rule, and it keeps you from overpaying for a rate you will not enjoy long enough to recover.
Points in a Rising-Rate Environment
When rates are climbing, locking a lower rate with points can feel urgent, but the same break-even logic applies — you still need to stay long enough to recover the cost. A rising market may also mean you are less likely to refinance soon, which actually improves the case for points if you will hold the loan. Let your planned tenure, not the rate trend, decide; points pay when the loan lasts, regardless of the direction rates move afterward.
Frequently Asked Questions
Are points refundable if I refinance?
Generally no. Points are paid for the life of that loan; refinancing starts a new loan. That is why break-even timing is critical.
How many points can I buy?
Lenders cap it, often at two to four points, and there are underwriting limits on how much credit/charge is allowed. More points mean a lower rate but more upfront cash.
Do points lower my monthly payment?
Yes, by lowering the rate they reduce the payment, which can also help you qualify under DTI limits.
