Current workforce per department or role

Historical attrition rates

Projected business growth metrics

Use Excel’s table features to make data dynamic and easier to manage.

Step 2: Calculate Future Workforce Needs

Use formulas that adjust current manpower based on growth projections and expected

attrition. For example:

`Future Workforce = Current Workforce × (1 + Growth Rate) - (Current Workforce ×

Attrition Rate)`

This formula can be applied across different departments and roles to forecast headcount

over upcoming periods.

Step 3: Scenario Analysis with Excel’s What-If Tools

Excel’s What-If Analysis, including Data Tables and Goal Seek, allows you to test various

scenarios, such as:

What if sales grow by 10% instead of 5%?

How would a higher attrition rate affect staffing needs?

This helps in preparing flexible workforce plans that account for uncertainties.
