Headcount Model
Definition
A financial model component that projects the number, role, start date, and fully loaded cost of every current and planned employee across all departments for each period of the forecast. The headcount model is the primary driver of personnel cost in the financial model. Personnel cost is typically the largest expense category for early-stage companies, and a headcount model that is incomplete or uses salary rather than fully loaded cost produces a financial model that materially understates operating expenses.
Common Misapplication
The most common misapplication is maintaining the headcount model as a separate document from the financial model rather than as an integrated component. A headcount model that is not connected to the financial model by formula requires manual reconciliation each time the headcount changes, which creates the risk that the two documents diverge.
