Discount Points:
Buying Down Your Mortgage Rate

Discount points are prepaid interest paid at closing to reduce the mortgage interest rate. One point equals 1% of the loan amount and typically reduces the rate by about 0.25%. The decision to pay points depends on the break-even period, which is the time it takes for monthly payment savings to exceed the upfront point cost.

Key Takeaways

  • One discount point costs 1% of the loan amount and typically reduces the rate by approximately 0.25%, though the exact reduction varies by lender and market conditions.
  • The break-even period is calculated by dividing the point cost by the monthly payment savings. If the borrower holds the loan longer than the break-even period, points are profitable.
  • Discount points are different from origination points: discount points buy a lower rate, while origination points compensate the lender for processing the loan.
  • Points are most advantageous for borrowers who plan to hold the loan long-term, have excess cash at closing, and are locking in a favorable rate.
  • Discount points on a purchase mortgage are generally tax-deductible in the year paid, which reduces the effective cost and shortens the break-even period.
  • Points on a refinance typically must be amortized over the loan term for tax purposes rather than deducted upfront.
  • Borrowers should avoid paying points if they may sell or refinance within the break-even period, or if the cash would produce a higher return elsewhere (such as paying off high-interest debt).

How It Works

How the Rate Sheet Works

Every mortgage lender publishes a daily rate sheet (updated based on secondary market pricing) that lists the available interest rates and the corresponding points or credits for each rate. The sheet is structured around the par rate, which is the rate at which the lender charges zero discount points and offers zero lender credits. Rates below par require the borrower to pay discount points. Rates above par generate lender credits that can offset closing costs.

A simplified example of a rate sheet might look like this: 6.75% with a 0.50% lender credit, 6.625% with a 0.25% lender credit, 6.50% at par (zero points), 6.375% with 0.375 discount points, 6.25% with 0.75 discount points, 6.125% with 1.125 discount points, 6.00% with 1.50 discount points. Each step represents a tradeoff between upfront cost and long-term rate savings.

The rate sheet is not linear. The cost per 0.125% rate reduction may increase as the rate moves further below par. This means the first quarter-point reduction might cost 0.75 points, but the next quarter-point reduction might cost 1.0 point. Borrowers should evaluate each incremental rate reduction independently to ensure the additional points are still producing an acceptable break-even period.

Detailed Break-Even Analysis

The basic break-even formula is: Break-Even Months = Point Cost / Monthly Payment Savings. However, a more sophisticated analysis accounts for the time value of money. The $4,000 paid in points today has an opportunity cost: it could have been invested and earned a return. A borrower who can earn 5% annually on invested funds should compare the mortgage rate reduction to this alternative return.

If paying $4,000 in points saves $64 per month ($768 per year), the annual return on the point investment is $768 / $4,000 = 19.2%. This far exceeds the 5% opportunity cost, making points a strong financial decision. If the same $4,000 only reduced the payment by $25 per month ($300 per year), the return would be 7.5%, which is still favorable but less compelling. Borrowers should frame the point decision as a rate of return question: does the return on paying points exceed the return available on the best alternative use of that cash?

Tax effects also modify the analysis. If the borrower deducts the points in the year paid (purchase) or amortizes them (refinance), the effective cost is reduced by the borrower's marginal tax rate. A borrower in the 24% bracket paying $4,000 in points has an after-tax cost of $3,040, shortening the break-even period from 63 months to approximately 48 months in the example above.

Fractional Points and Custom Rate Reductions

Borrowers are not limited to paying whole points. Lenders offer pricing at fractional increments, typically in eighths or quarters of a point. A borrower who wants to reduce the rate by only 0.125% might pay 0.375 points ($1,500 on a $400,000 loan). This allows the borrower to fine-tune the upfront cost and rate combination to match their budget and holding period expectations.

Some lenders also offer temporary buydowns, which are distinct from permanent discount points. A temporary buydown reduces the rate for the first one to three years of the loan, after which the rate reverts to the note rate. The cost of a temporary buydown is paid upfront (often by the seller or builder) and does not permanently reduce the rate. Temporary buydowns are a separate concept from discount points and should not be confused with them.

How Points Interact with Lender Credits

Points and lender credits sit on opposite ends of the same pricing spectrum. Paying points means the borrower is buying a below-par rate by paying the lender cash. Accepting a lender credit means the borrower is accepting an above-par rate, and the lender pays the borrower (as a credit toward closing costs) from the premium it earns selling the loan at the higher rate.

The optimal position on this spectrum depends entirely on the borrower's situation. A borrower who is cash-constrained and needs help covering closing costs may benefit from accepting a lender credit at a slightly higher rate. A borrower with abundant cash who plans to hold the loan for 15+ years may benefit from paying multiple points to secure the lowest possible rate. Most borrowers fall somewhere in between, and the break-even analysis helps identify the best position for each individual.

Key Factors

Factors relevant to Discount Points: Buying Down Your Mortgage Rate
Factor Description Typical Range
Expected Holding Period The number of years the borrower plans to keep the loan. Longer holding periods increase the value of paying points because savings accumulate over time. Break-even periods for discount points typically fall in the range of four to seven years based on prevailing market pricing, though the exact timeline depends on the cost per point, the rate reduction achieved, and the total loan amount.. Holding periods beyond the break-even point generate net savings.
Available Cash at Closing Points require upfront cash. Borrowers should ensure they retain adequate reserves and emergency funds after paying points. One point on a $300,000 loan costs $3,000. Two points cost $6,000. This is in addition to the down payment and other closing costs.
Rate Reduction per Point The amount of interest rate reduction offered for each point varies by lender and market. Smaller reductions per point lengthen the break-even period. Commonly 0.125% to 0.375Each discount point, equal to 1% of the loan amount, traditionally reduces the rate by approximately 0.25 percentage points, per established industry practice. The exact reduction varies by lender and market conditions
Tax Deductibility Points on a purchase mortgage are generally deductible in the year paid, reducing the effective cost. Points on a refinance are amortized over the loan term. Tax savings equal the point cost multiplied by the borrower's marginal tax rate (e.g., 24% bracket saves $960 on $4,000 in points).

Examples

Long-Term Homeowner Paying One Point

Scenario: A borrower takes a $350,000 30-year fixed mortgage. The par rate is 6.50% with zero points (monthly P&I: $2,212). The lender offers 6.25% with 1 point ($3,500). The monthly payment at 6.25% is $2,155, saving $57 per month.
Outcome: Break-even period: $3,500 / $57 = 61 months (approximately 5.1 years). The borrower plans to stay in the home for at least 15 years and does not anticipate refinancing. Over 15 years (180 months), the total savings from the lower rate are $57 x 180 = $10,260, minus the $3,500 upfront cost, for a net benefit of $6,760. If the borrower is in the 24% tax bracket and deducts the points, the effective cost drops to $2,660, improving the net benefit to $7,600.

Borrower Likely to Relocate Within Five Years

Scenario: A borrower takes a $300,000 30-year fixed mortgage and is offered 6.75% at par or 6.50% with 1 point ($3,000). The payment difference is approximately $50 per month. The borrower's employer may transfer them in 3-4 years.
Outcome: Break-even period: $3,000 / $50 = 60 months (5 years). Since the borrower may sell within 3-4 years (36-48 months), they are unlikely to reach the break-even point. Over 42 months (midpoint estimate), they would save $50 x 42 = $2,100, but they paid $3,000 upfront, resulting in a net loss of $900. This borrower should not pay points and should consider the par rate or even accept a lender credit.

Evaluating Incremental Points on a Jumbo Loan

Scenario: A borrower with a $750,000 jumbo loan is offered 6.375% at par, 6.25% with 0.50 points ($3,750), or 6.00% with 1.25 points ($9,375). Monthly payments: $4,681 at 6.375%, $4,625 at 6.25%, and $4,497 at 6.00%.
Outcome: First increment (par to 6.25%): saves $56/month for $3,750 cost. Break-even: 67 months. Second increment (6.25% to 6.00%): saves additional $128/month for additional $5,625 cost. Break-even: 44 months. The second increment actually has a shorter break-even period, making it more attractive per dollar spent. Total savings going to 6.00%: $184/month for $9,375 total cost. Combined break-even: 51 months. This demonstrates why evaluating each increment separately provides better insight than just looking at the total.

Common Mistakes to Avoid

  • Paying points without calculating the break-even period

    Without the break-even calculation, the borrower has no way to know whether paying points is a good financial decision for their situation. The break-even period tells the borrower exactly how long they must hold the loan to recover the upfront cost. Skipping this calculation means making an uninformed decision that could cost thousands of dollars.

  • Paying points when cash reserves are thin

    Discount points require cash at closing. If paying points depletes the borrower's reserves below a comfortable level or below lender requirements, the borrower is trading long-term savings for short-term financial vulnerability. Adequate emergency reserves should be maintained after all closing costs, including any points, are paid.

  • Confusing discount points with origination points

    Origination points are a lender fee; discount points are optional prepaid interest. A lender quoting '1 point' might mean 1 origination point (a fee) rather than 1 discount point (a rate buydown). Borrowers should verify which type of point is being quoted and understand that only discount points reduce the interest rate.

  • Assuming the point-to-rate-reduction ratio is always the same

    The rate reduction per point varies by lender and market conditions. Assuming a fixed 0.25% reduction per point without checking the actual rate sheet can lead to incorrect break-even calculations. Always request the specific rate at each point level from the lender.

Frequently Asked Questions

What exactly is a discount point?
A discount point is prepaid interest equal to 1% of the loan amount, paid at closing to reduce the interest rate. For example, on a $300,000 loan, one point costs $3,000. The rate reduction per point varies but is typically around 0.25%. Points can be purchased in fractional amounts.
How do I calculate the break-even period for paying points?
Divide the total cost of the points by the monthly payment savings. For example, if 1 point costs $3,000 and saves $50 per month, the break-even period is 60 months (5 years). If you expect to keep the loan longer than 5 years, paying points is financially beneficial.
Are discount points tax deductible?
On a purchase mortgage, discount points are generally deductible in full in the year paid, provided IRS requirements are met. On a refinance, points typically must be amortized over the loan term. Consult a tax professional for guidance specific to your situation .
Can the seller pay for discount points?
Yes, the seller can pay discount points as part of a seller concession, subject to the maximum concession limits for the loan program. On conventional loans, the maximum seller concession depends on the LTV ratio. On FHA and VA loans, separate concession rules apply. See the page on seller concessions and credits for detailed limits.
Is it better to pay points or make a larger down payment?
It depends on the borrower's situation. A larger down payment reduces the loan amount (and therefore the total interest paid) and may eliminate or reduce mortgage insurance. Points reduce the rate but do not affect the loan amount. If the larger down payment crosses a PMI threshold (such as reaching 20% equity), it may be more valuable than paying points. A borrower already above 20% down would evaluate points purely on the break-even analysis.
What happens to my points if I refinance?
Discount points are a sunk cost once paid. If you refinance before reaching the break-even period, you have not recovered the upfront cost of the points. Any remaining unamortized points from a previous refinance may be deductible in the year the old loan is paid off . This is why the expected holding period is critical to the point decision.
How many points can I buy?
There is no universal limit on the number of discount points a borrower can purchase, but practical limits exist. Most lenders offer rate reductions for up to 2-4 points, beyond which the incremental rate reduction per point diminishes. Lender policies and investor guidelines set the maximum. Additionally, the IRS may scrutinize extremely high point payments as potentially exceeding what is customary for the area.
