WI² Temporary Workforce Cost Calculator

Could your recruitment agency effectively pay for itself?

One client told us that our connected workforce technology removed enough administration for it to avoid recruiting an additional administrator — a reported annual cost avoidance of approximately £35,000, including employer on-costs.

Client-reported example. The amount is approximate and will not apply to every operation.

Use your own figures to compare the potential value of reduced administration, avoided headcount and lower early attrition with the agency margin you pay.

A Fair Reaction

£35,000 sounds like a bold number.

You may be thinking this is simply another recruitment company using a large figure to get your attention.

“That would be a fair reaction.”

The figure is not the promise. The method is.

The £35,000 is not a promise that every business will achieve the same result. It is the approximate annual cost one client told us it avoided.

This calculator does not use an assumed saving or generic industry average. You provide the figures. It shows you the financial implication.

The Commercial Question

The calculation most agencies never show you

Most businesses compare agencies solely by the hourly margin charged. WI² compares the margin against the total costs removed from the wider operation:

Temporary Hours25,000annual hours
Agency Margin£25,000at £1.00 per hour
Potential Value£65,000£35k admin + £30k retention
Return Per £1 Margin£2.60for every £1 margin paid

“Your agency can tell you what it charges. Can it tell you what it saves?”

Illustrative example only. Actual results depend on the figures entered, operational circumstances and changes successfully implemented.

Interactive Calculator

Calculate the potential value in your operation

Start with administration and headcount. Early attrition is added separately where you have enough data to test it.

What does temporary-workforce administration cost you?

Include bookings, shift changes, worker communication, attendance, replacements, timesheets, payroll queries and reporting.

What could early attrition be costing you?

Administration is only the first potential saving. Every worker who leaves early creates repeat inductions, supervisor time and productivity loss.

Operational Value

Where can the value come from?

Not by cutting a few pence off an hourly margin, but by eliminating friction, time loss and turnover across the operation.

01

Avoid additional headcount

Reduce manual work associated with bookings, worker communication, attendance, replacements, hours processing and reporting — removing or delaying the need for extra administrative resource.

02

Release management time

Give supervisors, managers, payroll teams, HR and administrators fewer spreadsheets, calls, messages and queries, freeing capacity for productive operational focus.

03

Reduce repeat inductions & attrition

Identify patterns associated with shift times, departments, supervisors and assignment length so you can address the root causes of avoidable early leavers.

04

Improve workforce decision-making

Move beyond standard fill-rate reporting to understand who attends, who returns, where workers leave and where targeted intervention is required.

Operational Analysis

Administration is only the first cost.

Every worker who leaves early creates another recruitment process, another induction, additional supervisor time and reduced team productivity.

How shift intelligence protects retention

At another operation, workforce analysis indicated a relationship between a shift start time and early worker retention.

Following a change to the start time, the available data suggested that retention improved — meaning fewer potential replacements, repeat inductions and management interventions.

The precise financial value of a similar change will vary by operation. That is why the calculator asks you to use your own induction, replacement and management costs.

Questions & Answers

What this calculation does — and does not — claim

Is the £35,000 a guaranteed saving?

No. It is an approximate, client-reported example of annual role capacity released or additional employment cost avoided. Every calculator result is based on the visitor's own figures and assumptions.

Does released capacity count as cash?

Not automatically. It represents capacity that may allow an administrator to be redeployed elsewhere, a role to focus on higher-value work or additional headcount to be avoided. The calculator presents potential operational value, not a guaranteed cash saving.

How is the retention saving calculated?

Current early leavers equal annual inductions multiplied by the current attrition rate. Prevented early leavers equal that result multiplied by the selected percentage reduction. The retention saving equals prevented early leavers multiplied by the cost per early leaver. WI² Mentor coaches workers and Connect supports and engages them, but the selected reduction is a test scenario, not a guaranteed result.

Why is attrition optional?

Many businesses do not know their annual inductions or four-week attrition rate. The calculator does not invent those figures. Instead, it identifies the information gap and gives the client questions to ask their current agency.

Why compare savings with agency margin?

Agency margin is visible and easy to compare. The wider cost of administering and repeatedly replacing temporary workers is often less visible. Comparing the two helps a business consider the net value of the whole service, not only the hourly rate.

This calculator provides an illustrative estimate based solely on the information and assumptions entered by the user. It is not a guarantee of savings, retention improvement or financial performance. Actual outcomes depend on operational circumstances, implementation, workforce behaviour and verified baseline data. Released capacity may create value through redeployment, higher-value work or avoided additional headcount; it does not necessarily represent a direct cash saving.
