UK user here.
I have a spreadsheet to track sales and income and we have recently registered for VAT so I want to add a drop down box to mark yes or no for VAT purposes.
I've got the formula worked out to calculate VAT but how do I get Excel to work out if it should apply the formula.
In my simple brain I was thinking it would be something like;
IF(C2="yes",M2*0.2,=SUM(D2:L2), but that doesn't seem to work...........
Columns C-G are entries for expense amounts and it will extend over 25-30 rows.
=SUM(C40:G40)*0.2 (to work out VAT amount)
=SUM(C40:G40)-I40 (to work out NET total)
I want to put an extra column in with the drop down box of yes and no to activate the VAT calculate where applicable
