Income Tax Calculation Formula

The formulas on the column G calculates the taxes both based upon income K2 and the area It falls down (the column A).



I want a formula on the cell K4 which picks the tax calculated amount in the regarded area. (On eof the column A)



Since Income is 30000 (K2) (It falls the area of 53000, so the values up to 53000) the formula on the K4 has to return 8880.



How can I do this?
