Mortgage points are upfront charges expressed as a percentage of the loan amount; discount points specifically purchase a lower offered interest rate.
Mortgage points are upfront charges expressed as a percentage of the mortgage amount. One point equals 1% of the loan amount. Discount points specifically mean points paid in exchange for a lower offered interest rate; percentage-based origination charges may also be informally called points but do not necessarily reduce the rate.
Points shift part of a mortgage’s cost to closing. Whether paying discount points lowers the borrower’s total cost depends on the exact rate reduction, cash required, loan term, prepayment, sale or refinancing date, and alternative use of the money. There is no universal rate reduction per point.
1% of the mortgage amount, so the dollar cost changes with loan size.If P is the mortgage principal and d is the number of points, the point cost is:
For a $400,000 mortgage:
| Points | Percentage of loan | Dollar cost |
|---|---|---|
| 0.25 | 0.25% | $1,000 |
| 0.50 | 0.50% | $2,000 |
| 1.00 | 1.00% | $4,000 |
| 1.50 | 1.50% | $6,000 |
Points can be fractional. The point percentage measures the charge, not the interest-rate reduction. A lender might offer one point for one rate change on one day and a different change for another loan or market date.
| Feature | Discount points | Origination points or fees |
|---|---|---|
| Main purpose | Obtain a lower offered interest rate | Pay a charge associated with originating, processing, underwriting, or funding the loan |
| Rate effect | Should be explicitly connected to a lower rate | No rate reduction should be assumed |
| Common calculation | Percentage of loan amount | Percentage or flat dollar amount |
| U.S. Loan Estimate | Points reducing the rate are separately itemized in Origination Charges | Other lender charges can appear as separate items |
| Break-even analysis | Compare added upfront cost with payment and interest savings | Treat as a loan-acquisition cost when comparing lenders |
Some market participants use points loosely for any charge equal to a percentage of the loan. That language can hide the distinction. Ask the lender to identify the interest rate with and without discount points and separately itemize every origination charge.
Loan origination fee is the clearer term for a lender charge that does not purchase a lower rate.
Assume a borrower compares two hypothetical 30-year fixed-rate offers from the same lender on the same $400,000 mortgage:
| Offer | Interest rate | Discount points | Point cost | Monthly principal and interest |
|---|---|---|---|---|
| A | 6.50% | 0 | $0 | $2,528.27 |
| B | 6.25% | 1.00 | $4,000 | $2,462.87 |
The standard fixed-payment formula is:
where:
M is monthly principal and interest;P is principal;r is the monthly interest rate; andn is the number of monthly payments.Offer B lowers monthly principal and interest by $65.40:
The simple payment break-even period is:
Under this simplified view, cumulative payment savings overtake the point cost after about 62 monthly payments. If the borrower sells, refinances, or repays the loan before then, the points do not break even through scheduled payment savings.
This is not a recommendation or live rate quote. Actual offers can use different rates, terms, fees, payment dates, and point pricing.
The basic calculation is useful but incomplete. It can omit:
A more complete comparison models cash flows through several plausible holding periods and includes remaining loan balance. The economic break-even date may differ from the simple payment break-even date.
For each offer, record:
If one offer has a lower remaining balance, that difference is borrower equity and should not be counted as a financing cost. Comparing total payments alone can be misleading because part of each payment repays principal.
Points and lender credits generally move mortgage pricing in opposite directions.
| Pricing choice | Upfront effect | Rate and payment effect | Main risk |
|---|---|---|---|
| Pay discount points | More cash at closing | Lower rate and scheduled payment | Loan ends before upfront cost is recovered |
| Zero-point structure | Neither point cost nor rate-linked credit | Middle pricing option for that rate sheet | May not minimize cost for the actual holding period |
| Receive lender credit | Less cash needed for eligible closing costs | Higher rate and scheduled payment | Higher ongoing cost if loan remains outstanding |
A lender credit is not free money. In a rate-linked structure, the borrower accepts a higher rate than the comparable zero-credit offer. Some credits can arise for other reasons, so the disclosure and lender explanation should identify what the credit offsets and whether it changes the rate.
A permanent mortgage buydown commonly uses discount points or other pricing to obtain a lower rate for the loan term.
A temporary buydown is different. Funds subsidize scheduled payments for an initial period, while the note rate can remain unchanged. The source of funds, underwriting payment, subsidy schedule, and unused balance treatment should be reviewed separately.
Do not describe every seller contribution, lender credit, temporary subsidy, or origination charge as a discount point.
For many U.S. closed-end mortgages covered by the integrated disclosure rules, points paid to reduce the interest rate appear in the Origination Charges section of the Loan Estimate and Closing Disclosure. Lender credits appear separately and reduce disclosed cash to close.
Review:
A point quote on an informal worksheet should be reconciled to the official transaction documents. Other jurisdictions and excluded loan types can use different disclosures.
Points cannot be compared in isolation if the underlying offers differ. Ask each lender for pricing based on the same:
Then compare the interest rate, APR, lender charges, third-party costs, credits, monthly payment, cash to close, and cost over realistic holding periods. A lower rate with expensive points can cost more over a short period; a higher-rate lender-credit option can cost more when held longer.
The same rate-versus-cash tradeoff can appear in purchase and refinancing transactions. The expected remaining loan period is central.
For a refinance, include:
Restarting a long amortization can lower the payment while increasing total interest. A points analysis should not use monthly savings alone when principal, term, or cash-out amount also changes.
Do not assume points are deductible. In the United States, IRS Publication 936 contains conditions for whether qualifying points may be treated as home-mortgage interest and whether they are deducted in the year paid or over time. Purchase, improvement, refinance, property use, secured-debt, itemization, loan-limit, payment, and local-practice facts can matter.
Origination or service charges do not become deductible interest merely because they are expressed as points. Seller-paid points and financed points also require rule-specific analysis.
Tax rules differ by jurisdiction and change over time. Use the current official publication and qualified tax advice for a specific return.
