Concept
Theoretically, Operating Cost is the cost incurred in the routine delivery of goods or services during normal organisational activities. It represents the recurrent resources consumed to operate a healthcare service or intervention and excludes capital investment costs unless these have been annualised.
Mathematically, Operating Cost is represented as the sum of all recurrent cost components associated with ongoing operations over a specified period. It provides the total operating expenditure used in budgeting, costing studies and economic evaluations.
In practice, Operating Cost is measured by identifying and aggregating recurrent expenditures, including labour, consumables, utilities, maintenance, administration and other operating expenses from financial records, cost accounting systems or hospital information systems. In health economics, operating costs are estimated using micro-costing, gross costing or activity-based costing methods depending on the level of detail required.
Purpose
Used to estimate the recurrent cost of delivering healthcare services, support economic evaluation, inform budgeting and resource allocation, evaluate efficiency, and monitor organisational performance.
Mathematical Formulae
Primary Formula
Operating Cost = Labour Cost + Material Cost + Overhead Cost + Other Operating Expenses
Supporting Formulae
Operating Cost = � Operating Cost Components
Related Mathematical Methods
- Micro-costing
- Gross costing
- Activity-based costing
- Bottom-up costing
- Top-down costing
Example
A hospital outpatient clinic incurs annual staff costs of �820,000, consumable costs of �135,000, utilities of �48,000 and administrative expenses of �97,000.
Operating Cost = �820,000 + �135,000 + �48,000 + �97,000 = �1,100,000 per year
This operating cost can subsequently be divided by annual patient activity to estimate the operating cost per consultation.
Excel Implementation
| Function | Example Formula | Health Economics Application |
|---|---|---|
| SUM | =SUM(B2:E2) | Calculates total operating cost by summing recurrent cost components. |
| SUMIFS | =SUMIFS(C:C,A:A,"Operating") | Aggregates operating costs by expenditure category. |
| PivotTable | Cost Category ? Sum of Cost | Summarises operating costs across departments or programmes. |
VBA (Optional)
Automate the aggregation of operating cost categories across multiple departments to produce standardised cost reports for economic evaluation.

Frequently Asked Questions (6)
What is an operating cost?
The recurring cost of an organisation's ongoing operations, such as staffing, supplies, and utilities, as distinct from one-off capital investment.
Source: Horngren, Datar & Rajan 2015
What does an operating cost include?
It covers the recurring resources consumed in running a service: pay for the staff employed, medicines, consumables and other supplies, utilities and premises running costs, maintenance, service contracts, and the share of corporate functions supporting delivery. It also includes the depreciation charged on assets in use, which is the operating consequence of past capital spending. What it excludes is the purchase of assets themselves, which falls to capital. Financing charges on borrowing sit alongside these, and although they arise from past capital decisions they fall on the operating position for as long as the borrowing is outstanding.

Where is the boundary between operating cost and capital drawn?
The boundary is set by whether the spending buys something used across more than one period, and organisations apply a monetary threshold below which items are treated as operating regardless of their life, since capitalising small purchases costs more in administration than the accuracy is worth. Maintenance that keeps an asset in its existing condition is operating; work that extends its life or increases its capacity is capital. The distinction is a convention and is applied inconsistently in practice.
Source: Gapenski 2015
Why does the operating cost boundary matter for decisions?
The two are usually funded from separate budgets under different rules, so a proposal can be affordable in one and not the other, and organisations facing an operating constraint have an incentive to structure spending as capital or the reverse. Leasing rather than purchasing equipment converts capital into operating cost, which changes where the pressure falls without changing the resources consumed. Decisions taken on this basis optimise against the budget structure rather than against cost.

How does operating cost relate to the total cost of an asset?
The purchase price is usually a minority of what an asset costs over its life once staffing to operate it, consumables, maintenance, training, utilities and eventual disposal are counted. A capital appraisal considering only the acquisition therefore understates the commitment substantially, and the operating consequences continue for as long as the asset is in service. Any capital proposal should quantify the operating cost it creates, and its absence is the most common defect in business cases.

How is operating cost controlled?
Most of it is committed rather than discretionary in any given year, since staffing, contracts and premises cannot be altered quickly, so short-run control acts on a small margin covering agency staffing, discretionary supplies and deferrable maintenance. Sustained reduction requires changing what the service does or how it is configured. This is why repeated in-year cost control efforts concentrate on the same few lines and why they deliver diminishing amounts.
