Multiple Hacks to Forecast Expenses in Excel

1. Using the TREND Function

   • 1. Input Historical Data: Begin by entering your historical expense data into Excel.
     2. Select the Range: Highlight the range of cells containing your historical expenses.
     3. Apply the TREND Function: Use the formula =TREND(known_y’s, known_x’s, new_x’s) to forecast future expenses. The known_y’s are your historical expenses, known_x’s are the time periods, and new_x’s are the future time periods for which you want to forecast expenses.

     3. Forecast Future Expenses: Use the trend from the moving averages to predict future expenses by extending the trend line.

3. Using Excel’s Forecast Sheet

   • 1. Enter Historical Data: Input your historical expense data in two columns—one for the dates and one for the expenses.
     2. Highlight Data: Highlight the data range.
     3. Create Forecast Sheet: Go to the Data tab, select Forecast Sheet, and choose your forecast options. Excel will automatically generate a forecast based on your historical data.

4. Using Scenario Analysis

   • 1. Create Scenarios: List your expenses under different scenarios (e.g., best-case, worst-case, and most likely).
     2. Apply Scenario Manager: Go to the Data tab, click on What-If Analysis, and select Scenario Manager. Input your different scenarios and forecast accordingly.
