Before you can do this exercise, you'll need to download and unzip this file (if you have any problems doing this, click here for help).

You need a minimum screen resolution of about 700 pixels width to see our exercises. This is because they contain diagrams and tables which would not be viewable easily on a mobile phone or small laptop. Please use a larger tablet, notebook or desktop computer, or change your screen resolution settings.

You have been commissioned  by a famous celebrity (definitely A list) to model their expenditure and income, to see why they keep running into debt.  Open the workbook in the folder above to begin.

Create the following inputs:

  • A basic living allowance of £20,000 for each of the first 3 months followed by £30,000 for each of the remaining 9 months
  • An amount for the star's overseas homes starting at £10,000 for the first month and rising by £1,000 a month to £21,000 in the last month
  • An amount for sex, drugs and rock and roll of £5,000 for each of the first two months, then £6,000 for each of the remaining 10 months

Your spreadsheet should now look something like this:

Your formatting will look different

Add a revenue section to the Inputs sheet.  This consists of two separate inputs:

  • A month-by-month fee, beginning at £10,000 in month 1 and rising in equal £5,000 amounts to £65,000 in month 12
  • A single-cell input for a multiplier for guest appearances, etc, initially equal to 150% (this should go in column D)

Calculate the star's revenue, costs and "profit" on the calculations sheet - here is what it might look like, with suitable number formatting applied:

Notice that the positive and negative numbers line up neatly
