Standard costing sounds simple on paper: fix a cost in advance, compare it with the actual cost, and act on the difference. In practice, this technique only works if certain groundwork is done first. Skip the groundwork, and the variances you calculate will mislead rather than guide you. This post walks through the essential pre-requisites that make standard costing reliable – cost centres, account classification, the type of standard you choose, and the process used to set and maintain those standards.

Why the groundwork comes before the numbers
Standard costing is a control technique that compares actual costs against pre-set benchmarks so management can act on the gaps between them. Before any benchmark is fixed, an organisation needs a clear structure for where costs are incurred, how they are recorded, and who is accountable for them. Without this structure, variances get attributed to the wrong department, and corrective action ends up targeting the wrong people.
Establishing cost centres
A cost centre is a location, person, or piece of equipment for which costs are separately identified and traced back to units of output. According to IGNOU’s study material on standard costing, a centre built around people is called a personal cost centre, while one built around a location or a machine is called an impersonal cost centre. Cost centres exist so that costs can be pinned down and controlled at the point where they actually happen, rather than lumped together at the level of the whole factory.
Matching accountability with authority
While setting up cost centres, it has to be clear who is responsible for the costs incurred in each one. A supervisor who has no control over how materials are purchased should not be held accountable for a material price variance. ICAI’s study material also distinguishes standard cost centres, where output can be measured and input requirements clearly specified, from discretionary cost centres such as an advertising department, where the input-output relationship is harder to define. Standard costing applies most cleanly to the first type.
Classifying accounts systematically
Once cost centres are in place, the accounting system needs a matching structure. Every cost centre and cost object should be coded so that related expenses can be assigned to it automatically and consistently. This coding is what allows an organisation’s cost information to be pulled quickly and compared period after period, instead of being reconstructed manually each time.
The Cost Accounting Standard on classification of cost issued by the Institute of Cost Accountants of India lays out the dimensions along which costs are usually sub-classified: by nature of the expense, by traceability to a specific cost object, by function or activity, and by behaviour – fixed, variable, or semi-variable. A standard costing system needs accounts classified along these lines because the standards for direct materials, direct labour, and overheads are set and monitored separately, and each behaves differently as output changes.
Deciding what type of standard to set
This is where many organisations run into trouble. A standard is only useful if the people being measured against it consider it fair and achievable. Four broad categories are commonly used, and each sends a different signal to the shop floor.
| Type of standard | What it assumes | Typical use |
|---|---|---|
| Ideal standard | Best possible prices, best equipment, maximum efficiency, no wastage or idle time | Rarely used for control; mainly a long-term aspirational benchmark |
| Normal standard | Average performance achievable over a full trade cycle, covering both peak and slack periods | Useful for long-term planning, less useful for day-to-day efficiency checks |
| Basic (bogey) standard | A fixed benchmark from a chosen base year, kept unchanged for years | Used mainly to study cost trends over time, not for current control |
| Expected (attainable) standard | Efficient but realistic operating conditions, allowing for normal wastage and downtime | The most widely used standard for actual cost control |
Ideal standards
An ideal standard is fixed at the level of cost achievable only under perfect conditions – no scrap, no breakdowns, no rest periods, and the best possible use of every resource. Educational material on cost accounting notes that very few companies actually use ideal standards for routine control, because they generate adverse variances almost every single period, regardless of how well the workforce actually performs. Constant adverse variances tend to demotivate staff rather than push them toward improvement.
Normal standards
A normal standard is set at the average level of performance expected over a longer period, ideally long enough to smooth out one full business cycle of peaks and troughs. Study material on standard costing explains that normal activity is defined as the number of standard hours needed, at normal efficiency, to meet average sales demand over a run of years. This makes normal standards useful for broad planning, though they are too static to catch short-term inefficiencies.
Basic or bogey standards
A basic standard is fixed once, using a chosen base year, and is deliberately left unrevised for a long stretch of time – the way a statistician might use a fixed base year for a price index. Because prices and methods drift over the years, variances calculated against a basic standard mostly reflect the passage of time rather than current efficiency, so this type is used more for tracking long-run trends than for controlling today’s costs.
Expected or attainable standards
An expected standard, sometimes called an attainable or currently attainable standard, is pitched at a level that a reasonably efficient worker or machine can reach under normal working conditions, including allowances for ordinary wastage and downtime. Because a mix of favourable and adverse variances is expected under this standard, it gives management a genuinely useful picture of where performance is slipping, which is why most organisations rely on it as the working standard for day-to-day control.
Setting standard costs through a defined procedure
Choosing the right type of standard is only half the job. The standard also has to be calculated correctly, and this calls for a structured process rather than a guess by a single manager.
The role of a standard costing committee
Most organisations that run standard costing set up a dedicated committee to fix standards, typically made up of the production manager, purchase manager, personnel manager, and other relevant functional heads, as noted in commerce department study material on standard costing. Bringing these functions together matters because material standards depend on purchasing conditions, labour standards depend on staffing and skill levels, and overhead standards depend on production planning – no single department has full visibility into all three on its own.
Building standards on technical data, not guesswork
ICAI’s chapter on standard costing describes how physical standards for material quantity and labour time are usually derived from technical specifications supplied by the engineering or production department, factoring in the method of production, the skill level of workers, and relevant external constraints such as labour law. Standards built this way, on documented technical inputs, hold up far better under scrutiny than standards guessed from memory or copied from a previous year without review.
Keeping standards accurate and reliable over time
A standard costing system is only as good as its ongoing maintenance. Markets, wage rates, and technology all move, and a standard that was realistic two years ago can quietly become useless. As summarised discussions of standard costing’s limitations point out, rapid shifts in market conditions and technology can make old standards obsolete, leading to inaccurate benchmarks and weaker decisions if they are not revisited regularly.
Beyond periodic revision, the system needs the genuine cooperation of the staff who work with it every day. University study material on costing systems highlights that an effective costing system needs the full cooperation of staff, needs to be simple enough to operate consistently, and needs to stay closely linked with financial accounting so that cost figures and financial results can be reconciled without friction. A technically perfect standard that the shop floor does not trust or understand will not deliver reliable control, no matter how carefully it was calculated.
Taken together, these four pre-requisites – cost centres, account classification, the right type of standard, and a disciplined setting procedure – decide whether a standard costing system produces variances worth acting on, or numbers that nobody trusts.
What do you think? If you were setting up standard costing for a small Indian manufacturing unit with limited technical staff, would you lean toward normal standards or expected standards, and why? And how much damage do you think a poorly defined cost centre can do to the accuracy of an otherwise well-calculated standard?
