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, 292 variable loans anyone could take were read Friday 18 September. 178 of them list an offset account among their published features. Among those, the going rate is 5.89%, against 5.84% across every loan and 5.85% among loans whose feature list has no offset. So at the going rate, an offset costs 0.05 points this morning.
The going rate is the rate at which a third distinct lender appears in the sorted list. It is not the lowest rate anyone publishes. One lender's price is worth nothing to a borrower that lender says no to.
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 | 5.84% | 5.79% | 6.34% | 101 | 292 |
| Loans listing an offset | 5.89% | 5.79% | 6.49% | 88 | 178 |
| Loans listing features, but no offset | 5.85% | 5.84% | 6.13% | 69 | 114 |
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
- Every rate comes from the lender's own feed, published under the Consumer Data Right. Nobody types a rate in. The rates are read each morning, and the figures on this page are taken once, from that morning's read.
- A rate counts only if anyone could take it. Loans for a particular group only, by their published conditions or by their name, are left out. So is any lender the capture has stopped reaching.
- Each loan is counted once per profile, at its lowest advertised rate. A lender that prices five bands by how much you owe is one loan here, not five.
- 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
- These are advertised rates, not offers. The rate a lender writes for you depends on you and on the lender. It can say no.
- They are prices for a new customer. What a lender charges the customers it already has is published nowhere.
- The rate is not the cost. Fees sit outside it. What a comparison rate adds measures how far.
