When procurement teams evaluate labour hire proposals, markup rate is almost always the primary comparison metric. It’s a single number, it’s easy to compare across providers, and it creates a clear ranking. The problem is that it measures one component of what labour hire actually costs your organisation — and it does a poor job of predicting whether a provider will be cheap or expensive in practice.
Total cost of workforce is the framework that captures what markup rate misses. It asks a different question: not what does the provider charge per bill hour, but what does the entire arrangement cost us — including the costs that never appear on an invoice. For organisations with significant contingent workforce spend, the gap between markup rate and total cost is where most of the value leakage occurs.
If your organisation is in the process of evaluating providers or restructuring how you manage contingent labour spend, Programmed’s MSP and people solutions team works with procurement and HR leaders to build visibility across exactly these cost drivers.
Key takeaways
- Markup rate covers the provider’s employment on-costs and margin — it does not capture the internal costs your organisation absorbs when things go wrong.
- Attrition, compliance failures, quality issues, and administrative burden are all real costs that a low-markup provider can generate at scale.
- A simple total cost model — even one using rough estimates — produces a materially different comparison than markup rate alone.
What markup rate actually covers
To understand what markup rate misses, it helps to understand what it includes. The provider’s markup covers their employment on-costs — superannuation, workers compensation insurance, payroll tax, annual and personal leave entitlements, and any allowances payable under the relevant award or enterprise agreement. It also covers the provider’s internal cost to run the account — sourcing, payroll processing, compliance management — and their margin.
In other words, markup rate is the price of employing a worker through an intermediary. It says nothing about the quality of the worker sourced, the likelihood that worker will stay, the compliance posture of the provider, or the internal burden placed on your team to manage the arrangement. Those are separate variables, and they are large ones.
The hidden costs markup rate obscures
Four cost categories consistently appear in organisations that examine their contingent labour spend rigorously:
Attrition and re-sourcing cost. Every time a worker leaves and is replaced, your organisation absorbs a re-sourcing cost — the administrative time involved, plus the productivity loss during the gap and the early ramp-up period of the replacement worker. A new worker, even an experienced one, is not fully productive from day one. In complex or specialised roles, it takes weeks to reach full output. Providers with high attrition in your role categories extend this cost continuously. A 2% lower markup with 40% six-month attrition is materially more expensive than a 2% higher markup with 15% six-month attrition.
Compliance failure cost. Non-compliance in a labour hire arrangement — underpayments, incorrect award classifications, failure to pay proper entitlements — creates exposure for both the provider and the host. Fair Work investigations, back-pay liability, and reputational damage are not theoretical. Hosts have faced adverse publicity and financial exposure because a provider was non-compliant. The cost of a compliance failure is not in the markup — it arrives separately and often unexpectedly.
Quality and rework cost. Poor-quality placements — workers who lack the skills they were represented as having, or who perform below the standard required — generate supervisor time, rework, and in safety-critical environments, incident risk. Quantifying this cost requires connecting placement quality to output quality, which most organisations don’t systematically do. But when it’s measured, it is rarely trivial.
Internal administration cost. Managing invoices with errors, handling onboarding disputes, chasing missing documentation, managing poor-performance processes for workers you don’t technically employ — all of this consumes internal time. For organisations with large contingent workforces managed through multiple providers without a vendor management system, the internal administration cost can run to the equivalent of one or more FTE positions annually.
The productivity curve: why the first weeks matter
Every placement starts with a productivity gap. The worker needs time to learn the environment, the team, the systems, and the specific requirements of the role before they reach full output. This is not a labour hire problem — it affects direct hires too. But in labour hire arrangements with high turnover, the productivity curve restarts continuously.
Consider a role where a new worker reaches full productivity at week three. If your attrition rate means the average tenure in that role is eight weeks, you are running at reduced productivity for roughly 37% of the time. If a different provider’s average tenure for the same role is twenty weeks, the same calculation drops to 15%. The difference in markup rate between those two providers almost certainly doesn’t compensate for that productivity gap.
This is why tenure data — not just fill rate — is one of the most useful questions to ask a provider during evaluation.
A simple total cost framework
You don’t need a sophisticated model to produce a more useful comparison than markup rate alone. The following framework uses five inputs, most of which can be estimated from existing data:
- Direct wage cost: Base rate plus applicable allowances and loadings. This is in the markup, but worth isolating.
- Provider margin component: The portion of markup above on-cost recovery. Ask providers to break this out.
- Internal administration cost: Estimated hours per week spent by internal staff managing the arrangement, times an internal cost rate.
- Attrition and replacement cost: Average cost per replacement (sourcing, re-induction, productivity ramp-up) times expected attrition rate over the contract period.
- Compliance risk cost: Probability-weighted exposure — the estimated cost of a compliance event, discounted by its likelihood given the provider’s compliance track record.
Even with rough estimates on the last two items, running this model for two providers with different markup rates and different quality profiles will typically produce a different ranking than markup rate alone. The exercise also clarifies which input has the most leverage — which is usually attrition or compliance, not the margin component.
Questions to ask providers that reveal total cost implications
Standard RFP questions focus on price and capability. The following questions are more diagnostic:
- What is your fill rate for this role category in our industry and region? Low fill rates indicate sourcing gaps that will create delays and substitutions.
- What is your average tenure for placements in organisations similar to ours? Tenure data is the most direct proxy for attrition cost.
- What does your quality assurance process look like — how do you screen for skill accuracy, not just availability? Providers who can describe a specific process here are more likely to deliver matched placements.
- What is your replacement guarantee, and what does it cover? A genuine replacement guarantee (within thirty days, at no additional charge) signals confidence in placement quality.
- What is your Fair Work compliance history — have you had any FWO findings, infringement notices, or back-pay events in the past three years? This question separates providers who take compliance seriously from those for whom it is a theoretical concern.

FAQ
Is total cost of workforce modelling only worth doing for large contingent spends?
The modelling overhead is low — even a simple spreadsheet-based version produces useful insight. For organisations spending $2M or more annually on contingent labour, the exercise almost always surfaces value leakage that exceeds the cost of doing it. For smaller spends, the most useful question is simpler: what has our attrition rate been, and what has each replacement event cost us? That single number often drives better procurement decisions than markup rate comparison.
How do I get providers to share tenure and attrition data honestly?
Include it in your RFP as a required response item with a defined format — average tenure at twelve months for the relevant role category, attrition rate by reason (voluntary, performance, client-initiated). Providers who can’t or won’t answer specifically are telling you something. Providers who answer with specific data are differentiating on a dimension they believe is competitive.
What is a reasonable markup rate for industrial or trades labour hire?
Markup rates vary significantly by role category, state, and market conditions. The more useful question is whether the markup is realistic for the compliance and service standard you require. Providers with very low markups in categories with significant award complexity or compliance obligations are either absorbing losses (unsustainable) or cutting corners on compliance (your problem eventually). A rate that’s competitive but not the lowest in the market, from a provider with strong compliance data and tenure performance, is typically better value than the lowest rate available.
How does a VMS help with total cost visibility?
A vendor management system creates a single data layer across all your contingent workforce activity — fill rates, time-to-fill, tenure, spend by category, attrition reasons, compliance status. Without it, total cost analysis relies on estimates. With it, the inputs are actual data. The improvement in decision quality is significant, particularly for organisations managing multiple providers across multiple sites.
