Again you think of your workbook as a lot of tables to print out The sheet Forecast_Budget is OK to show to boss, but a disaster for calculations. P.e.
1. You need to add jan.20. You have to redesign ALL your formulas which refer to range G : CO;
2. You decided to employ a new analyst/designer/whatever. You have to edit formulas for 'Forecasted Spend based on Burn Chart' in all 3 tables, and the whole Total table;

It looks like all values you calculate on sheet Forecast_Budget, you can calculate directly from TimeSheet. The only exceptions are:
1. Rate, which is best to enter into Employees table, or into separate Rates sheet, when an employee can have different rates in different situations;
2. Total Budget, for which you need also a separate sheet, p.e. Projects.

And how are those analysts, designers, etc. connected with timesheet? Must there be a column Employee instead of Analyst, and every employee has an appointment/role?

At last, which records from Timesheets are connected to which table on Forecast_Budget? The total one must be obviously the sum of other 2, but how aren't rates there neither same as in other tables, neither sums from other tables?
