Google Sheets, one distinct cell to calculate multiple values for multiple cells

Question

I'll try my best to explain the issue,

So I have created a spreadsheet which calculates my working hours, breaks, fortnightly pay and fortnightly tax automatically.

The problem I am having is, I need to copy/paste the fortnight schedule/listing every fortnight, which is fine because everything still works perfectly, except the tax section. No matter how much extra I earn the second fortnight, it will still reference the first fortnight and apply the same tax.

SAMPLE SHEET

https://docs.google.com/spreadsheets/d/1kEBNssfw_hSoJ8DQZ6oSym7PHf5tJYEgNnaW3zYijbo/edit?usp=sharing

explained in dot points first, just as an example:

• sheet1!a2 = fortnight1 earnings
• sheet1!a16 = fortnight2 earnings

• sheet1!a31 = fortnight3 earnings

  • Sheet2!a5 = referenced earnings from a2,a16,a31

  • Sheet2!b5 = tax calculator, calculates tax separately for all references in Sheet2!a5

  • Sheet1!b2 = fortnight1 calulated tax from sheet2!b5 for sheet1!a2

  • Sheet1!b16 = fortnight2 calulated tax from sheet2!b5 for sheet1!a16
  • Sheet1!b31 = fortnight3 calulated tax from sheet2!b5 for sheet1!a31

This is essentially what I'm trying to achieve.

Basically...

I want the tax for a2,a16 and a31 earnings to be calculated from the the same sell in sheet2 (cell b5) . I don t want to make duplicates of the calculator in sheet2 for each fortnight.

Answer 1

In B2 type:

=IF(ISNUMBER(A2)=FALSE,"-",VLOOKUP(A2,'Fortnight Tax'!$A$6:$B$15,2))

And then copy paste it in B16 , B31 and etc. If you copy the cell instead of the formula, it will adjust to A16 , A31 etc.
