Mortgage points are an upfront payment for a lower interest rate in US home lending. Australian borrowers need to assess their lender’s own fee and discount terms because the US points model does not establish what a local offer buys.
A lower rate can save less than the fee costs if you refinance early. Compare the total cost over the time you expect to keep the loan, including any ongoing charges.
Understand Mortgage Discount Points
A US mortgage discount point is prepaid interest, with one point costing 1% of the loan amount. The borrower pays it at settlement in exchange for a lower rate.
The Consumer Financial Protection Bureau’s explanation of discount points says the rate reduction depends on the lender, loan and market. One point does not guarantee a particular reduction.
A basis point measures a rate difference. One basis point is 0.01 percentage points, so a fall from 6.00% to 5.75% is 25 basis points. Buying one discount point and receiving a one-percentage-point rate cut are different things.
Correct interpretation: a fee of one point costs 1% of the loan amount. Incorrect interpretation: that fee automatically cuts the interest rate by 1%. An upfront charge for arranging a loan also needs its own explanation, because a setup fee alone does not establish a rate discount.
Separate Australian Loan Pricing From the US Model
Australian home-loan pricing needs a product-by-product comparison of the quoted rate and fees. A package discount, an application fee and a negotiated discount each have different terms.
For example, CommBank’s Wealth Package lists an annual fee of $395 for benefits that include interest rate discounts on eligible loans. That is an ongoing package charge, with eligibility conditions, rather than a standard US point priced at 1% of the loan.
An application fee is an upfront establishment cost. Do not assume it buys a lower rate unless the lender expressly ties the payment to that reduction. A negotiated discount is the rate concession in your written quote, which can exist without a separately purchased point.
These distinctions do not rule out an Australian lender proposing an upfront fee for a lower rate. They mean you need the actual offer’s terms before applying the points calculation. Compare equivalent loan amounts and repayment structures, including the treatment of any fixed-rate period.
Compare an Upfront Cost With Interest Savings
An upfront fee breaks even when the accumulated savings exceed the extra costs. Use the difference between the offers’ fees, since costs charged equally by both offers cancel out.
Consider a hypothetical $500,000 interest-only loan kept for five years. Offer A charges 6.00% a year with no extra upfront fee. Offer B charges 5.80% with an extra $3,000 upfront fee.
Assume the balance and rates stay unchanged for the full five years. The fee is paid from savings, both offers have identical other fees and there is no offset balance. Tax effects and the return forgone on that cash are excluded.
| Measure | Calculation | Result |
|---|---|---|
| Annual interest saving | $500,000 × 0.20% | $1,000 |
| Simple break-even | $3,000 ÷ $1,000 | 3 years, or 36 months |
| Net saving after two years | $2,000 less $3,000 | $1,000 behind |
| Net saving after five years | $5,000 less $3,000 | $2,000 ahead |
If Offer B also costs an extra $200 each year, its net annual saving falls to $800. Break-even then takes 3.75 years, or 45 months. A fee that looks affordable over five years can be expensive if you refinance after two.
A falling balance changes the result. Extra repayments or money in an offset reduce the interest charged, so the same rate gap produces fewer dollars of savings. If the interest-bearing balance falls to $400,000, a 0.20-percentage-point gap saves $800 a year before extra fees.
For principal-and-interest repayments, model both loans over the same remaining term. Compare interest and fees, then compare the balances still owed at your planned exit. A smaller monthly repayment is not, by itself, the full measure of the saving.
If a variable rate discount changes or a fixed period ends, recalculate from that point. If you add the upfront fee to the loan, include interest on the financed fee. Include discharge costs and any applicable fixed-rate break cost when testing a refinance date.
Ask the Right Questions About a Local Offer
Ask your broker or lender for written offers that show exactly what the fee buys and when the discount ends. A quote needs enough detail to compare the same borrowing scenario without relying on the label “points”.
Moneysmart’s guide to choosing a home loan recommends comparing loan rates, fees and features using the lender’s Key Fact Sheet. Its comparison rate combines interest with most fees, but your own holding period still needs a separate cost comparison.
- Record the rate with the fee and the rate without it for the same loan amount, purpose and repayment type.
- List upfront, recurring and exit charges. State whether the payment is refundable and whether it is paid in cash or added to the debt.
- Identify the discount’s duration and eligibility conditions. Establish what happens after refinancing, switching products or ending a package.
- Compare costs at your likely exit and an earlier exit. Include the projected balance, offset use and any fixed-rate break costs.
If a fee buys several package benefits, value only the benefits you expect to use. Keep the written quotes beside the calculation so you can see which assumptions produce the saving before you agree to pay.
