What an offset account costs
An offset account is a bank account tied to your loan. Money in it counts as if you had paid it off the loan, for as long as it sits there. I measured what lenders charge for one.

For a home you live in, paying it down, 316 variable loans anyone could take were read Monday 2 November. 198 of them list an offset account among their published features. Among those, the going rate is 5.89%, against 5.85% across every loan and 5.89% among loans whose feature list has no offset. So at the going rate, an offset costs 0.04 points this morning.
The going rate is where a third distinct lender appears in the sorted list, so one lender's odd price cannot set it.
A feature list is what the lender published, not everything it sells. A loan whose list has no offset may still come with one when you ask. So this page reads the lists as written. The comparison, for a borrower who needs an offset, leaves out a loan whose list has no offset. A loan that publishes no list at all is kept, in a second run shown beside the first. The two are never averaged.
Three ways of counting
| Loan | Going | Lowest | Middle | Lenders | Loans |
|---|---|---|---|---|---|
| Every loan anyone could take | 5.85% | 5.69% | 6.54% | 104 | 316 |
| Loans listing an offset | 5.89% | 5.69% | 6.69% | 91 | 198 |
| Loans listing features, but no offset | 5.89% | 5.85% | 6.34% | 70 | 118 |
What an offset is worth to you
That depends on one number: how much you keep in it. Money in an offset earns you your loan rate, tax free, for as long as it is there. Keep little in it and a loan without one at a lower rate wins. Keep a lot in it and the offset wins. Work it through on how fast to pay it off.
How this is worked out, and what it does not tell you
How it is worked out
- Rates come from each lender's own feed under the Consumer Data Right, read each morning. Nobody types one in.
- A rate counts only if anyone could take it. Loans for particular groups, and lenders the capture cannot reach, are left out.
- Each loan counts once per profile, at its lowest advertised rate.
- Variable loans for a home you live in, paying it down only. An offset on an interest-only or investment loan is priced the same way and can be read off the comparison for that loan.
- "Lists an offset" means the lender's published feature list for the loan names one. A lender that offers an offset and leaves it off the list is counted as listing none.
What it does not tell you
- Advertised rates, not offers. A lender can say no.
- New-customer prices. What existing customers pay is published nowhere.
- The rate is not the cost. Fees sit outside it. What a comparison rate adds.

Free, and not advice. It knows only what the lender publishes, not what you could negotiate. A licensed broker does this for a living. Who made this. What this site collects.
