Monitor your income with a spreadsheet

Besides, the spreadsheet will also provides the average, max and min income for the 1st and second half of the year.

2. Calculate average income.

4. Calculate min income.
   Repeat the same procedure as in step 1, but now use "MIN" instead of "SUM".
   


5. Calculate average income for the 1st half of the year.
   Repeat the same procedure as in step 1, but only select 6 rows of cells (B6 to B11), since we need to calculate the average of income for 6 months.
   


6. Calculate max income for the 1st half of the year.
   


7. Calculate min income for the 1st half of the year.
