In this simple example, the fixed fee is $1000. The entire amount is invoiced and work has not yet begun.
Complete % is the same as earned %, it is your stage progress as indicated by your project manager expressed as a percentage. As a value, however, these two are slightly different- complete % is multiplied by the fee, while earned % is multiplied by budget.
Like in a spreadsheet, when an amount is in parentheses ( ), this amount has been deducted from the stage.
