Mortgage Points Explained: When Buying Down Your Rate Makes Sense
Mortgage points are one of the most misunderstood aspects of home financing. A discount point is simply prepaid interest — you pay a lump sum at closing in exchange for a lower interest rate over the life of the loan. The concept is straightforward, but the decision is not: whether buying points saves money depends on how long you keep the loan, your tax situation, and what else you could do with that money. Lenders love points because they get cash upfront. This guide helps you determine whether points benefit you or just benefit the lender.
What Mortgage Points Are
One discount point equals 1 percent of the loan amount. On a $300,000 loan, one point costs $3,000. Each point typically reduces the interest rate by 0.25 percent, though this varies by lender and market conditions. Some lenders offer fractional points — you can buy 0.5 points for $1,500 and get a 0.125 percent rate reduction.
Origination points are a separate concept. An origination point is a fee the lender charges for processing the loan — it is a cost, not a rate reduction. Some lenders charge origination points and some do not. When comparing offers, distinguish between discount points (which lower your rate) and origination points (which are just fees). Only discount points give you an ongoing benefit.
The Break-Even Calculation for Points
The break-even period is the key metric. Divide the cost of the points by the monthly savings they create. If one point costs $3,000 and reduces your monthly payment by $45, break-even is 67 months (about 5.5 years). If you keep the loan longer than 67 months, the points save you money. If you sell or refinance sooner, you lose money on the deal.
This calculation assumes you hold the original loan for the full break-even period. If interest rates drop and you refinance in 3 years, the points you paid on the original loan are lost. If you sell the home in 4 years, same result. The break-even calculation is only meaningful if your expected time in the home (and in the loan) exceeds the break-even period. Most homeowners refinance or move within 7 to 10 years, which means a break-even period of 3 to 5 years is the practical target.
When Buying Points Makes Sense
Points make the most sense when you are certain you will stay in the home and keep the loan for a long time — at least 7 to 10 years past break-even. A buyer who plans to live in the home for 20 years and is getting a 30-year fixed rate is an ideal candidate for points. The upfront cost is recovered in a few years and then generates pure savings for the remaining life of the loan.
Points also make sense when they allow you to qualify for the loan. If your debt-to-income ratio is borderline, buying a point to reduce the rate (and therefore the monthly payment) can bring your DTI under the qualifying threshold. In this case, the points serve a functional purpose beyond pure savings calculation — they make the purchase possible.
When Points Are a Bad Deal
Points are a poor choice if you expect to sell or refinance within 5 to 7 years. First-time buyers, in particular, often underestimate how likely they are to move — job changes, family growth, and lifestyle shifts frequently prompt moves within 5 to 10 years. If there is a reasonable chance you will not stay past break-even, the money spent on points is wasted.
Points are also a poor use of capital if the money could be deployed elsewhere more productively. Using $6,000 for points that save $90 per month (break-even in 67 months) means your capital earns an effective return of about 5 to 6 percent. If you could invest that $6,000 at 8 to 10 percent in a retirement account, the investment wins. The opportunity cost of capital matters when evaluating points.
- Bad for: first-time buyers who may move within 5-7 years
- Bad for: buyers in areas with frequent job relocations
- Bad for: borrowers who plan to refinance when rates drop
- Bad for: buyers who would deplete savings to pay for points
- Good for: long-term homeowners in stable locations
- Good for: buyers who need to reduce DTI to qualify
Negative Points: Lender Credits
Negative points work in reverse — the lender pays you (as a credit toward closing costs) in exchange for accepting a higher interest rate. One negative point might add 0.25 percent to your rate but give you a $3,000 closing cost credit. This reduces your upfront costs at the expense of higher monthly payments.
Lender credits make sense when you plan to sell or refinance within a few years, when minimizing cash needed at closing is a priority, or when you want to preserve cash for other investments or an emergency fund. The trade-off mirror images the points analysis: if you keep the loan past the break-even period, you lose money compared to the no-credit option. If you exit the loan before break-even, the credits saved you money.
Tax Implications of Mortgage Points
Discount points paid on a purchase mortgage are generally deductible in the year you buy the home, providing an immediate tax benefit. Points paid on a refinance must be deducted over the life of the loan (amortized). If you refinance a 30-year mortgage with $3,000 in points, you deduct $100 per year for 30 years — a modest annual benefit.
The tax deduction reduces the effective cost of points. If you are in the 24 percent tax bracket and pay $3,000 in points on a purchase, the deduction saves $720 in taxes, making the effective cost $2,280. This shortens the break-even period and makes points more attractive for buyers who itemize deductions. However, the standard deduction increase in recent tax reform means fewer homeowners itemize, potentially eliminating this benefit for many buyers.
Frequently Asked Questions
How much does one mortgage point cost?
One point costs 1 percent of the loan amount. On a $300,000 loan, one point is $3,000. On a $200,000 loan, one point is $2,000. You can buy fractional points (like 0.5 or 0.75) for a proportional cost and rate reduction.
How much does a point lower the interest rate?
One point typically reduces the rate by 0.25 percent, but this varies by lender and market conditions. Some lenders offer less reduction per point. Always ask the lender for the specific rate reduction per point and calculate the break-even based on the actual numbers, not the rule of thumb.
Are mortgage points worth it for a first-time buyer?
Usually not. First-time buyers have the highest likelihood of moving or refinancing within 5 to 7 years, which is often before the break-even point. The money spent on points would typically be better used for a larger down payment, closing costs, or a home repair fund. Consider points only if you are confident you will stay for 10 or more years.
Can I negotiate mortgage points?
Yes. Points are not fixed — they are part of the rate-cost tradeoff that lenders offer. You can negotiate the rate, the points, and the closing costs as a package. Getting Loan Estimates from 3 or more lenders gives you leverage to negotiate better terms with your preferred lender.
Is paying points the same as making a larger down payment?
No. A larger down payment reduces your loan amount, which reduces your monthly payment and may eliminate PMI. Points reduce your interest rate on the existing loan amount. Both reduce monthly costs, but a larger down payment also reduces total interest paid and increases your equity position. In most cases, a larger down payment provides more benefit than paying points.
