Excel formula for calculating stamp duty in South Australia (SA), Australia (that's where Adelaide is)

Because I'm a completionist, I feel the urge to write Excel formulas to calculate stamp duty for every state in Australia. Here's the formula for South Australia from Revenues SA.



Unlike other states, Revenues SA calcualate liablility to include cents. Hence, no ROUND() in this formula.

If you're trusting an internet stranger's formula without comparing it with the official SA stamp duty calculator, you're nuts. The intent of these formulas is to calculate ballpark stamp duty.
