A quick post of how to calculate the Stamp Duty of a property with Excel, in my example I am using the Western Australia Residential Rate Dutiable value.

Stamp Duty
Cutoff [$]  Rate [%]  Duty [$]  Formula
0           1.9       0    0
120000      2.85      2280      =C3+(A4-A3)*B3/100
150000      3.8       3135      =C4+(A5-A4)*B4/100
360000      4.75      11115     =C5+(A6-A5)*B5/100
725000      5.15      28452.5   =C6+(A7-A6)*B6/100

Property Value        500000    
Duty                  17765     =VLOOKUP(C9,A:C,3,TRUE) + (C9-VLOOKUP(C9,A:C,1,TRUE))*VLOOKUP(C9,A:C,2,TRUE)/100

Update, next day
This also works for Individual income tax rates;

Tax Rates
Cutoff [$]  Rate [%] Tax [$]  Formula
0           0        0        0
6000        15       0        =C3+(A4-A3)*B3/100
37000       30       4650     =C4+(A5-A4)*B4/100
80000       37       17550    =C5+(A6-A5)*B5/100
180000      45       54550    =C6+(A7-A6)*B6/100

Income               100000
Tax                  24950    =VLOOKUP(C9,A:C,3,TRUE) + (C9-VLOOKUP(C9,A:C,1,TRUE))*VLOOKUP(C9,A:C,2,TRUE)/100

In Excel, find the value on the last row as a function, not VBA
