[SOLVED] Excel Formatting Recap

[bradenterpstra01]

I am a student wanting to make an Excel sheet for finding how many dining dollars (money on student ID card) I can spend each week. I know I could just use a calculator but wanted to make an Excel sheet for practice. Here is what I need it to do:



I have 200 dining dollars to spend this semester. There are 15 weeks remaining in the semester. That means I can use ~$13.33 each week on extra food. Now, I don't eat much extra, so I won't spend 13 a week. So, each week, the total would need to be recalculated by dividing the current amount remaining by the number of weeks remaining.



So, in other words, at 15 weeks, I can spend 13.33 a week. If I only spend 5 dollars that week, that means the new total is 195 and at 14 weeks remaining, I can spend 13.92 a week from that point on and so on and so on.



How can I automate that in Excel?

Clunky, but it works

Column A: Week # (Static)
Column B: Dining Dollars spent each week (manually entered)
Column C: Dining Dollars Remainder (=sum(C2, -B3) Incremented for each week)
Column D: Weekly Average Remaining (=C3/14 incremented weekly so the next row reads =C4/13, =C5/12, and so on) You can calc this as well.

Once the formulae are set, all you need to do is enter the weekly dollars spent and the rest calculates.

Another idea

Column A = week number or week ending/start date
Column B = weekly budget
Column C = actual spend
Column D = (Total of column B - Total of column C) / CountA of remaining weeks in column A.

To count remaining weeks and be able to copy the formula down use for example A4:A$15 where row 4 is the current row and row 15 is the end week/row.

Is it a one time influx of $200, or is it a weekly addition of $13.33?
Daily expenditure or weekly tracking? (do you remember what you spent last Wednesday?)

The next Col/Row 6 = the Previous Col/Row 10.

Can you provide an example file or something? I could not get the formulas to work properly. Thanks!
