Home Loan Package Fee: A Break-Even Worksheet

Short answer

A lower interest rate can be outweighed by an annual home loan package fee. For a rough one-year comparison with the same unchanged interest-bearing balance, multiply that balance by the rate difference, then subtract the extra annual fees.

Illustrative annual advantage = balance x rate difference as a decimal - extra annual fees.

This is a screening calculation, not a repayment schedule or product recommendation. For estimates that account for regular principal repayments, compare matching balances and terms in the Loan Comparison Calculator.

Start with two actual alternatives

Record the rate payable on each loan, not just a discount from one lender's advertised reference rate. A large advertised discount does not show whether the resulting rate is lower than an alternative offer.

ASIC Moneysmart's home loan guidance recommends comparing loan rates, fees and features using Key Facts Sheets. It also explains that a comparison rate combines interest and most fees. Ask which charges and features apply to the specific amount and term being considered.

A package can bundle several products. For example, Westpac describes an annual-fee package with eligible home loans and other products. That demonstrates the arrangement, not a recommendation or a statement that every package works the same way. The example below uses invented figures and no lender's quoted offer.

Worked example: a $400 annual fee and a 0.10 percentage point gap

Assume two hypothetical loans have the same $300,000 balance throughout a full year. Loan A charges 6.10% with no ongoing fee. Loan B charges 6.00% with a $400 annual fee. Assume no repayments, offset, compounding, other fees or rate changes for this simple comparison.

Loan B's lower rate saves $300 of interest in this scenario, but its fee is $400. Its combined annual amount is therefore $100 higher.

The rate gap is 0.10 percentage points, which is 0.001 as a decimal. Using 0.10 in the multiplication would overstate the benefit by a factor of 100.

Calculate the illustrative break-even balance

With only the rate and fee difference changing:

Break-even balance = extra annual fee / rate difference as a decimal.

For the example, $400 / 0.001 = $400,000. That is the unchanged interest-bearing balance at which the model's $400 interest difference equals the extra fee.

A positive final column means a lower combined amount for Loan B under these assumptions. It does not mean the package is suitable or that a lender will offer it.

If the rate gap is zero, dividing by zero has no meaning: there is no interest-rate saving to offset a positive fee. If the packaged rate is higher, this particular rate-discount calculation does not produce a useful positive break-even balance.

A worksheet for the details that change the answer

Where one package covers several loan splits, check how often the fee is charged. Do not automatically apply one whole package fee to every split, or assume all splits receive the same rate discount.

Give an unused bundled benefit a value of zero in this worksheet. An advertised fee waiver is not a saving against the alternative unless that alternative would actually incur the charge.

Take the comparison further

Use the Loan Comparison Calculator for a fuller loan scenario, checking how it handles fees and the selected term. The guide to comparison rates explains the wider cost measure. If changing lenders, also read the refinancing checklist before treating a recurring annual difference as a switching benefit.

A lower monthly repayment is not the same as a lower total cost when the remaining terms differ. Keep the term consistent, or explicitly show that it changed. The remaining loan term guide explains that input.
