How governments evaluate costs when considering privatization: focus on avoidable versus unavoidable expenses

When planning privatization, governments should separate avoidable from unavoidable costs to gauge true savings. This distinction informs budgeting, strategic planning, and the financial viability of outsourcing services, ensuring decisions rest on what can actually be eliminated.

When governments weigh privatizing a service, the hard math doesn’t just involve price tags and bids. It hinges on a clear-eyed view of the real money involved—what the state actually spends today, and what it would save tomorrow if a contractor took over. The most practical compass for that financial terrain is the distinction between avoidable costs and unavoidable costs. This isn’t a flashy gadget or a shiny new framework; it’s the kind of decision-relevant clarity that turns a fuzzy notion of “savings” into a trustworthy, numbers-backed plan.

Let’s unpack what these terms mean in everyday government budgeting, and why they matter for privatization decisions. Then we’ll look at how to identify them, how to present them to stakeholders, and how to avoid common missteps along the way.

Avoidable vs Unavoidable: The core idea

Think of a city’s public transportation service, say, a bus route managed by a municipal department. If the service is privatized, the private operator would typically pick up most of the labor and maintenance costs, and the city would stop paying for those items directly. Some costs, however, would stay no matter who operates the service. These are unavoidable costs.

• Avoidable costs: These are expenses that disappear or shrink substantially if the service is outsourced. They often include labor costs, overtime, certain procurement expenses, routine maintenance that the contractor will handle, and perhaps portions of energy use if the new operator uses different suppliers or efficiencies. If a service is privatized, these costs become the contractor’s responsibility, not the government’s.

• Unavoidable costs: These are the baseline expenses that the government would incur even after privatization. Think of core oversight and governance costs, specific statutory obligations, certain public safety protections, long-term financing or debt service tied to the asset, and regulatory or compliance costs that the government must bear regardless of who runs day-to-day operations.

Why this distinction is essential

Here’s the thing: simply tallying total costs before and after privatization can be misleading. A headline figure might show big savings, but without separating avoidable from unavoidable costs, you don’t know what’s realistic to cut or reallocate. That’s like judging a plant’s health by just looking at its leaves—ignore the roots, and you’ll miss the real story.

By focusing on avoidable costs, governments can:

• Get a clearer picture of true, implementable savings.

• Assess the scale of efficiency gains possible through privatization.

• Make more informed comparisons between in-house delivery and external provision.

• Better align budgeting and policy goals with the actual financial impact of the change.

If avoidable costs are small, privatization may still make sense for other reasons—efficiency, service quality, risk transfer, or strategic priorities—but the raw financial upside will be different from a scenario where millions of dollars in labor or procurement expenses could be cut.

A practical way to proceed

1. Map the current cost structure

Start with a transparent ledger of all costs tied to the service. Break them into categories: personnel, facilities, equipment and maintenance, energy and consumables, contracts with vendors, overhead, compliance, and governance. Don’t shy away from the granular stuff—the more specific, the better your downstream decisions will be.

2. Identify cash flow drivers

Ask: Which costs are tied to the ongoing operation of the service and would likely transfer to a private operator? Which costs exist due to the public sector’s institutional arrangements and would still need to be funded after privatization? This is where you separate the “what’s left on the government’s plate” from the “what the contractor would handle.”

3. Distinguish fixed versus variable in a practical sense

Be careful with the usual labels. In government accounting, “fixed” isn’t a guarantee that the cost will persist in any privatized arrangement. Some traditionally fixed costs may become variable under private management (for example, contract-based labor or scalable maintenance agreements). The key is to focus on whether the government can eliminate or significantly reduce the expense through outsourcing.

4. Model scenarios with care

Create scenarios that reflect different privatization models: full privatization, public-private partnership (PPP), or outsourcing of specific functions. For each model, re-calculate which costs are avoidable and which stay. The goal isn’t to force a single verdict but to illuminate the financial contours of each path.

5. Include non-financial but material considerations

Costs aren’t only dollars and cents. Consider risk transfer, service quality, attainment of public policy objectives, and the potential impact on citizens. A slightly higher avoidable cost in money terms might be worth it if it comes with better reliability, safety, or equity of access.

Tools and methods that help

• Activity-based costing (ABC) with a government twist

ABC helps assign costs to specific activities, making it easier to see which activities would vanish or persist under privatization. The trick is to adapt it to public-sector realities: service levels, regulatory overhead, and public accountability requirements should be baked in.

• Cost-benefit or cost-savings reconcilations

Rather than a single “savings” line, build a layered analysis: direct cost savings from outsourcing, transition costs, potential renegotiation of legacy contracts, and any contingencies. You want a living model, not a static snapshot.

• Sensitivity analysis

Test how sensitive the outcomes are to changes in key assumptions—volatility in labor costs, energy prices, or vendor performance. This helps avoid over-optimistic projections and highlights where the biggest financial uncertainties lie.

• Risk registers

Pair the financial analysis with a risk register that identifies what could go wrong in privatization and who bears the risk. This isn’t just risk for risk’s sake; it informs the cost side by attaching probabilities and potential financial impacts.

Common pitfalls to watch for

• Treating all costs as fixed in a blanket way

Not every cost will stay put or be unavoidable once a private operator enters the scene. Some costs might become variable, depending on performance metrics, service levels, or volume-based pricing in a contract.

• Ignoring the cost of oversight

Governments must still monitor, regulate, and ensure accountability. Oversight costs, while not tied to day-to-day operations, remain real and can be significant. Don’t bury them in the background.

• Over-relying on headline savings

Public services carry value beyond the bottom line—consistency, accessibility, and trust. A razor-thin financial gain might be offset by reputational risk or public dissatisfaction if service quality dips.

• Skipping a thorough stakeholder map

Different departments, unions, communities, and interest groups will weigh in with concerns and expectations. A robust analysis accounts for these voices and incorporates them into the financial narrative where possible.

A practical example in context

Imagine a city runs a municipal waste collection service. If privatized, the city would likely shed many labor and maintenance costs, and the contractor would bring in equipment and route optimization. However, there would still be unavoidable costs: regulatory compliance, certain environmental monitoring obligations, and some administrative governance functions. The city would need to evaluate whether the realized savings from outsourcing justify any transition costs, potential changes in service levels, and the ongoing need to maintain oversight.

The payoff is not merely a lower line on a spreadsheet. It’s a clearer understanding of what changes are truly within reach, what will require negotiation with vendors, and where the public interest must remain the guiding star.

Narratives that help communicate the idea

• The “before and after” picture

Describe the current cost mix, highlight the unavoidable anchors, and then present the anticipated shifts under privatization. People grasp stories that show moving pieces rather than abstract numbers.

• The cost-of-risk lens

Explain how predictable, contract-driven costs can reduce budget surprises, while outlining how risk transfer to a capable private provider might stabilize overall spending—if the governance framework is solid.

• The citizen-centered angle

Remind readers that efficient, well-managed privatization has a real impact on service continuity, accessibility, and fairness. When done thoughtfully, it can free up resources for urgent public needs.

A few closing reflections

Deciding how to structure government services in a world of tight budgets and rising expectations isn’t a purely mechanical exercise. It’s a balancing act between financial prudence, public accountability, and the practical realities of delivering essential services. The avoidable-versus-unavoidable cost framework acts like a lens that clarifies where savings genuinely lie and where compromises are baked into the deal.

As you walk through the numbers, keep the human element front and center. Consider the communities affected, the workers who rely on stable, fair terms, and the long tail of governance that keeps the public trust intact. The goal isn’t simply to privatize for the sake of a leaner budget; it’s to design arrangements that sustain service quality, financial health, and civic confidence for years to come.

If you’re mapping this for a project or policy brief, start with a clean inventory of costs, then isolate the avoidable bits. Let the unavoidable costs be your constant, and let the avoidable ones be your variable. That pairing—simple in concept, powerful in practice—often reveals the most honest, actionable path forward. And in the end, that honesty is what keeps public services resilient, responsive, and worthy of the public’s trust.
