Workforce planning value calculator

Build the business case for your planning function in one place. This tool implements the three-tier method from the white paper The Business Case for Workforce Planning — a conservative figure you can evidence, a likely figure you’re confident in, and an upside figure you name without over-claiming. Edit any input. Nothing leaves your browser.

A. Your operation

Number of agents (FTE)

Front-line headcount the plan covers.

Fully loaded cost per agent (£/yr)

Salary plus on-costs. Labour base = FTE × this.

Labour base: £—

B. Conservative tier — gains you can evidence

Recoverable staffing mismatch (% of labour base)

Over-staffed intervals + overtime premium you can recover. Evidence from interval occupancy.

Annual overtime spend (£)

From payroll.

Overtime reduction achievable (%)

Current attrition (%)

Attrition reduction (percentage points)

Points off the rate from better schedules / workload balance.

All-in cost per leaver (£)

Use the cost-of-attrition calculator for a defensible figure.

C. Likely tier — confident but harder to prove

Annual service protection value (£)

Avoided SLA penalties, abandoned/repeat contacts, churn. Estimate conservatively with finance.

D. Upside tier — named, not banked

Decision-quality value, one-off (£)

Magnitude of one bad capacity/sourcing decision good planning de-risks. Shown separately; not in the headline.

E. What planning costs

Annual planning function cost (£)

Fully loaded cost of the planning team (or the proposed hire/system) you’re justifying.

How to read this

Lead your business case with the conservative number — every component is independently checkable, so it survives scrutiny. Present the likely figure as the realistic expectation and the upside as what’s at stake, without folding it into the headline. If net value is positive on the conservative tier alone, the function pays for itself on the figure you can prove — the strongest position to argue from. Full method and worked example in the white paper.
