Mortgage Points vs. a Lower Interest Rate in 2026: How to Calculate the Breakeven Period
Mortgage points let you exchange a higher upfront closing cost for a lower mortgage rate. The offer may sound attractive, but a lower monthly payment does not automatically mean the points are a good deal. You first need to determine how long it will take for the payment savings to recover the upfront cost.
When comparing mortgage points vs. a lower interest rate, the key variables are the loan amount, the rate reduction, the price of the points, your available cash, and how long you realistically expect to keep the mortgage. Selling the home is not the only event that matters. Refinancing also ends the original loan and can prevent you from reaching the breakeven point.
The calculations below compare monthly principal-and-interest payments. Property taxes, homeowners insurance, homeowners association dues, mortgage insurance, and other housing expenses are excluded because they generally do not change when you purchase discount points.
Mortgage Points vs. a Lower Interest Rate: What You Are Paying For
Discount points are prepaid interest paid to a lender at closing in exchange for a lower mortgage rate. One discount point typically costs 1% of the loan amount.
- One point on a $250,000 mortgage typically costs $2,500.
- One point on a $400,000 mortgage typically costs $4,000.
- Two points on a $400,000 mortgage typically cost $8,000.
One point often reduces the interest rate by approximately 0.125 to 0.25 percentage points, but there is no universal rate reduction. A point might lower one lender’s rate by 0.25 percentage points while producing a smaller discount from another lender. Pricing can also change with market conditions, loan type, credit profile, property use, and the length of the rate-lock period.
For example, paying one point might reduce a quoted rate from 6.50% to 6.25%. That is a reduction of 0.25 percentage points, not a 25% reduction in the interest rate.
Discount points are not the same as origination fees
Discount points specifically purchase a lower rate. An origination fee compensates the lender for processing or making the loan. A lender may express both charges as percentages of the loan, so borrowers should not assume every fee labeled as a “point” reduces the rate.
Points are also different from a temporary buydown. Permanent discount points generally reduce the rate for the applicable life of a fixed-rate loan. A temporary buydown may reduce the borrower’s effective payment for only the first one, two, or three years, often using funds contributed by a seller, builder, or lender.
Review the lender’s Loan Estimate carefully. It should identify the loan terms and disclose points and other lender charges. Compare offers using the same loan amount, loan program, down payment, lock period, and estimated closing date. Otherwise, differences beyond the points may distort the comparison.
The Mortgage Points Breakeven Formula
The basic breakeven calculation is:
Cost of points ÷ monthly principal-and-interest savings = breakeven period in months
To convert the result into years, divide the number of months by 12:
Breakeven months ÷ 12 = breakeven period in years
Suppose discount points cost $5,000 and reduce the monthly principal-and-interest payment by $90. The calculation would be:
$5,000 ÷ $90 = 55.6 months
That is approximately 4.6 years. If the borrower sells or refinances after three years, the accumulated payment savings would not recover the $5,000 upfront cost. If the borrower keeps the loan beyond the breakeven month, the subsequent payment reductions begin producing gross savings under this simplified method.
Breakeven is a useful starting point, not a complete return analysis. The formula does not account for the potential return the upfront cash could have earned elsewhere, differences in the remaining loan balance, possible tax treatment, or the value of keeping additional cash available.
Worked Example: $400,000 Loan With and Without Points
Consider two offers for a $400,000, 30-year fixed-rate mortgage:
- Option A: 6.50% interest with no discount points.
- Option B: 6.00% interest with two points costing $8,000.
The estimated payments are as follows:
| Loan feature | No-points option | Two-point option |
|---|---|---|
| Loan amount | $400,000 | $400,000 |
| Loan term | 30 years | 30 years |
| Interest rate | 6.50% | 6.00% |
| Cost of points | $0 | $8,000 |
| Estimated monthly principal and interest | Approximately $2,528 | Approximately $2,398 |
| Estimated monthly payment savings | — | Approximately $130 |
The simplified breakeven calculation is:
$8,000 ÷ $130 = 61.5 months
Dividing 61.5 by 12 produces approximately 5.1 years. The borrower would generally need to keep the mortgage for slightly more than five years before the cumulative payment reductions exceed the $8,000 cost of the points.
The word “generally” matters. This result measures gross payment savings against the point cost. A more complete analysis would also compare the remaining principal balance under each rate and consider what else the borrower could have done with the $8,000.
How Loan Term, Refinancing, and Cash Affect the Decision
A planned three-year stay
Assume the borrower expects to sell after 36 months. At approximately $130 per month, the cumulative payment reduction would be:
36 × $130 = $4,680
That is $3,320 less than the $8,000 paid for points. Based on the simplified payment-savings method, the borrower would not reach breakeven before selling.
A planned 10-year hold
If the borrower keeps the same mortgage for 120 months, the estimated cumulative payment reduction would be:
120 × $130 = $15,600
After subtracting the $8,000 cost of the points, the simplified gross savings would be approximately $7,600. This does not include opportunity cost, tax effects, or differences in the outstanding balance, but a 10-year holding period is comfortably beyond the estimated 62-month breakeven point.
Refinancing resets the analysis
Points paid on the original mortgage do not transfer to a new loan. If the borrower refinances in year four, the original mortgage ends before reaching the estimated five-year breakeven point. The borrower must then evaluate any new rate and closing costs separately.
No one can know with certainty whether refinancing will become attractive. Future rates, property values, credit qualifications, and refinancing costs can all change. Borrowers who expect a reasonable chance of refinancing within a few years should account for that uncertainty before committing substantial cash to points.
Available cash may be more important than the rate
Paying points should not leave a buyer without adequate money for closing costs, emergency reserves, repairs, moving expenses, or near-term homeownership needs. A lower payment can help monthly cash flow, but the benefit may not justify using most of the borrower’s liquid savings at closing.
There is also an opportunity cost. Cash spent on points cannot simultaneously remain in a savings account, pay down higher-cost debt, fund a larger down payment, or be invested. Any potential alternative return is uncertain unless the money is held in a guaranteed account or instrument, so borrowers should compare reasonable scenarios rather than assume a particular investment return.
Larger loans do not automatically create a better deal
A larger loan can generate a larger dollar reduction in the monthly payment, but the points also cost more because they are calculated as a percentage of the loan. The breakeven period becomes shorter only when the lender’s combination of point cost and rate reduction is proportionally more favorable. Loan size alone does not guarantee a faster breakeven.
Important Details a Simple Breakeven Calculation Misses
Monthly savings are not the entire financial picture
Use an amortization schedule to compare the loans at the date you expect to sell or refinance. Each mortgage payment includes principal and interest, and the interest portion generally declines as the balance falls. Because a lower rate changes the allocation of each payment, two loans can have different remaining balances even if the simple payment comparison suggests a particular breakeven month.
A more detailed comparison should include:
- The upfront point cost.
- Cumulative principal-and-interest payments through the expected holding period.
- The remaining principal balance on each loan at that date.
- Any lender credits or other fees that differ between the offers.
- A reasonable estimate of the opportunity cost of the upfront cash.
Potential tax treatment depends on the borrower
Mortgage points may be deductible as mortgage interest in some circumstances, but eligibility and the timing of the deduction depend on factors such as whether the loan is for a primary residence, whether the borrower itemizes deductions, how the funds are used, and whether the transaction is a purchase or refinance.
Tax laws and individual circumstances can change. Review current IRS guidance and consult a qualified tax professional rather than treating a possible deduction as guaranteed. A tax deduction also does not reimburse the full cost of the points; it may only reduce taxable income when applicable.
Points on an ARM require additional scrutiny
With an adjustable-rate mortgage, points may primarily affect the introductory rate period. Borrowers should examine how long that initial rate lasts, the adjustment index, the lender’s margin, adjustment caps, and the maximum possible rate. A breakeven period extending beyond the initial fixed period may be less reliable because future payments can change.
Temporary buydowns require a different calculation
A temporary buydown does not necessarily change the underlying note rate. Instead, money is set aside to subsidize part of the early payments. For example, a 2-1 buydown may reduce the effective payment rate by two percentage points in the first year and one percentage point in the second year before payments rise to the full note-rate amount.
Ask who is funding the buydown and what happens to unused funds if the loan is refinanced or paid off early. Do not evaluate a temporary buydown using the permanent-points breakeven formula without reviewing its specific terms.
What to Do Next Before Choosing Points
-
Request comparable Loan Estimates.
Ask each lender for zero-point, one-point, and multiple-point options based on the same loan amount, loan type, down payment, lock period, and closing assumptions. -
Record the essential numbers.
Write down the interest rate, point cost, lender fees, monthly principal-and-interest payment, and annual percentage rate for each option. -
Calculate the simple breakeven period.
Divide the cost of the points by the monthly principal-and-interest savings, then divide the resulting months by 12. -
Compare breakeven with a realistic timeline.
Use the shorter of your expected time in the home and your expected time before refinancing. Include a margin for uncertainty rather than assuming your plans will occur exactly on schedule. -
Review an amortization schedule.
Compare cumulative payments and remaining balances at three, five, seven, and 10 years. -
Confirm whether the rate reduction is permanent.
Ask whether the quote represents permanent discount points or a temporary buydown and whether pricing could change before the rate is locked. -
Protect your cash reserves.
Confirm that paying points leaves enough money for the down payment, other closing costs, emergency savings, repairs, and near-term expenses.
The Bottom Line
Mortgage points can be worthwhile when the rate reduction is competitively priced, the borrower has sufficient cash, and the loan is likely to remain in place well beyond the breakeven period. They are less attractive when the buyer expects to sell or refinance soon, needs the cash for reserves, or receives only a small rate reduction for a substantial upfront charge.
For the $400,000 example, paying $8,000 to lower the rate from 6.50% to 6.00% saves approximately $130 per month and produces a simple breakeven period of about 62 months. That five-year threshold is the starting point for the decision—not the entire decision. Compare formal Loan Estimates, review the amortization results, and make sure the upfront payment fits your broader financial position before choosing points.
