Macbank ups the incentive

Macbank (Macquarie) have the highest advertised savings account rate in the market at this time - 4.85%. It is a level far better than any term deposit.

But it is a "welcome" rate - you only can get it for the first four months, and after that it reverts to 4.50%.

And also there is a limit of $250,000. For amounts $250,00 to $1,000,000 the 4.50% rate applies.

These are attractive offers.

But they have today (August 1, 2025) made them even more attractive. They have raised the upper limit to $2,000,000. 

That means a lot. 

Previously, above $1 mln the rate reverted to 2.25%. Now it doesn't revert to $2.25% until your funds in the account exceed $2 mln.

By our calculations, if you had $2 mln and accessed their "welcome rate" the extension will have improved your before tax interest earnings by $22,500 per year. It is an improvement of an overall effective rate from 3.39% to 4.51%.
