Stamp Duty Calculation

[Pat_Burrows1970]

Hello,

I have a SUMPRODUCT formula to calculate stamp duty in the UK below where F2 = the purchase price of a property. 

=SUMPRODUCT(--(F2>{0;250000;925000;1500000}),(F2-{0;250000;925000;1500000}), {0.03;0.05;0.05;0.02})

I want to edit this formula so that if F2 is less than 40000 then the stamp duty = £0 regardless of the above formula.

Can anyone assist me please?

Thanks,

Pat

=IF(F2<40000,0,SUMPRODUCT(--(F2>{0;250000;925000;1500000}),(F2-{0;250000;925000;1500000}),{0.03;0.05;0.05;0.02}))

Does this return the expected result?

If anyone comes across this thread more recently, rates have now changed...

=IF(B4<40000,0,SUMPRODUCT(--(B4>{0;250000;925000;1500000}),(B4-{0;250000;925000;1500000}),{0;0.05;0.1;0.12}))

Very useful - thank you!

The correct formula incorporating rates as of March 2024 is as follows;

=SUMPRODUCT(--(F8>{0;250000;925000;1500000}),(F8-{0;250000;925000;1500000}),({0;0.05;0.05;0.07}))

Note, the rates are incremental so for although its 10% SDLT from £925k to £1.5m, we have to use 5% increment over the previous tier.
