I'm trying to figure out how to get the monthly gross income based on the annual net income. The net income is computed by multiplying the monthly gross by 12 and then subtracting the annual tax.
The annual tax varies depending on the annual income. There is a fixed amount and a variable amount which is a percentage of the annual income less the lower limit for that range. The table is shown below:
A B C D E F
1 Annual Income Fixed Tax Excess Tax Monthly Annual
2 0 5000 0 0 900 10800
3 5000 8000 0 20%
4 8000 16000 600 25%
5 16000 40000 2600 30%
6 40000 160000 9800 32%
7 160000 48200 35%
If a person's monthly gross income is 900, then
net income =F2 - (LOOKUP(F2, A2:B7, C2:C7) + LOOKUP(F2, A2:B7, D2:D7) * (F2 - LOOKUP(F2, A2:B7, A2:A7)))
= 10800 - (600 + 0.25 * (10800 - 8000))
= 9500
Is getting the monthly gross income based on the annual net income possible in Google Sheets?
P.S. Not really sure about the title/question. Please edit accordingly.
