A VLOOKUP formula can be used to calculate a tax rate relative to income. After following a few simple steps, you will be able to quickly calculate Tax based on income levels.

Setting up the Data
- First, we setup our data so that the taxable income is in Column A and the Tax Rate in column B
- Enter the Income in cell E2 and leave cells E3 and E4 blank for now
- In this example, the Income used for the lookup is $100,000

Calculate Tax Rate Using VLOOKUP
The VLOOKUP function finds the adjacent value based on the specified lookup value
- The basic formula is =vlookup(lookup value, table array, column to return, Approximate Match [True/False])
- In cell E3 type this formula =VLOOKUP(E2,A3:B8,2,TRUE)
We can see in this example that the formula returned a Tax Rate of 22% because $100,000 falls between $82,000 and $158,000. If we were to put “False” in the Approximate Match piece of the formula, it would not have calculated properly since $100,000 doesn’t match any of the values in Column A exactly

*Now, all we have to do is apply the Tax Rate to the Income in order to calculate the Tax.
Calculate Tax Based on Rate
- The calculation for Tax is Income x Rate = Tax
- In cell E4 type this formula =E2*E3
