Standard Costing: Meaning, Types and Setting Standards

Updated 10 October 2026 · Fact-checked

Standard costing is a technique where you fix predetermined costs for materials, labour and overheads for a unit of output, compare them with actual costs, and analyse the differences (variances). To set standards, you decide quantity, price and time for each element, then multiply them to get a standard cost per unit.

Understand Standard Costing: Concepts and Setting Standards

A standard cost is a carefully predetermined cost of a unit of output under stated operating conditions. Standard costing is the technique of using these standards, comparing them with actual costs, and finding the reasons for differences so that management can act.

Think of it as a target set before production starts. If the standard cost of a unit is ₹500 and the actual cost is ₹540, the ₹40 gap is an adverse variance. Standard costing makes you ask why. Was the material price higher, was more material used, or was labour slower?

The main objectives are: to give a yardstick for measuring efficiency, to control cost through management by exception, to help in fixing selling prices, to value stock and work in progress at a uniform standard rate, and to help in planning and budgeting.

Standards are of different types. An ideal standard assumes perfect conditions with no waste, no idle time and no breakdown. It is rarely achievable and can demotivate staff. A basic standard is fixed for a long period and not revised; it is used as a base to measure trends. A normal standard is based on average performance over a business cycle. A current standard (attainable standard) is based on present conditions and is expected to be achieved with reasonable effort. Current standards are the most practical for control.

Standard costing is not the same as budgetary control or estimated costing. Estimated costs are guesses of what a cost will be, often based on past records, and are not used as a tight yardstick. Standards are scientifically set targets of what cost should be. Budgets are financial plans for the whole business or a function. Standards relate to a unit of output; budgets relate to total activity.

Key rules to remember

Standard cost per unit: Standard material + Standard labour + Standard overhead (variable and fixed); Each element is built as standard quantity (or time) × standard price (or rate).
Standard material cost: Standard quantity per unit × Standard price per unit of material; Standard quantity includes normal loss or wastage allowed.
Standard labour cost: Standard hours per unit × Standard wage rate per hour; Standard hours include allowance for normal idle time and fatigue where applicable.
Standard overhead rate: Budgeted overheads ÷ Budgeted base (units or hours); Calculate separately for variable and fixed overheads.
Standard overhead cost per unit: Standard overhead rate × Standard hours (or units) per unit; Base must be the same one used to compute the rate.
Standard input for given output: Standard input = Standard output ÷ (1 − normal loss %); Use when the question gives output required and a normal loss percentage on input.

How to solve Standard Costing: Concepts and Setting Standards questions

Use this method for any question on setting standards or explaining the concept.

1Identify what is asked: a definition, a comparison, types of standards, or a calculation of standard cost per unit.
2For a calculation, list the three elements: material, labour and overheads. Split overheads into variable and fixed.
3For material, fix standard quantity (including normal loss) and standard price (purchase price plus carriage, less discounts).
4For labour, fix standard time per unit (including normal idle time allowance) and standard rate per hour.
5For overheads, compute the rate as budgeted overhead ÷ budgeted base, then multiply by standard base per unit.
6Add the elements to get the standard cost per unit; then compute standard cost for the actual or required output if asked.
7For theory, write point-wise with a heading for each point, and add a one-line example or use.
8State a short conclusion, such as which standard suits control best (current standard).

Quickest way: Build the standard cost card in a table of lines

When to use it: Use when a numerical asks for standard cost per unit or a standard cost card from given data.

Write three rows: Material, Labour, Overhead, and put quantity × price beside each.
Adjust quantity for normal loss first: input = output ÷ (1 − loss %).
Compute overhead rate once, then multiply by hours or units.
Total the rows and re-check that each rate was applied to the right base.
For comparisons, remember one line: standards are unit-based and scientific; budgets are total-based and plans; estimates are rough forecasts.

Common mistakes in Standard Costing: Concepts and Setting Standards

Calling ideal and current standards the same.
Both sound like targets of good performance.
Fix: Ideal assumes perfect conditions with no loss. Current is attainable with reasonable effort and allows for normal loss and idle time.
Ignoring normal loss when fixing standard material quantity.
Students use the output quantity directly.
Fix: Divide required output by (1 − normal loss %) to get the input, then price the input.
Treating standard costing as identical to budgetary control.
Both use predetermined figures and compare with actuals.
Fix: Say standards are per unit and used for cost control; budgets are overall plans for a period and cover sales, cash and more.
Using total overheads instead of a rate per unit or hour.
Students skip the budgeted base.
Fix: Always divide budgeted overhead by the budgeted units or hours, then apply the rate to the standard base per unit.
Mixing variable and fixed overheads into one rate when the question gives them separately.
It looks quicker.
Fix: Compute two rates; they feed different variances later and may be asked separately.

Worked examples

Example 1

A product needs 10 kg of material as net output. Normal loss is 20% of input. Material costs ₹60 per kg. Standard labour is 4 hours at ₹50 per hour. Budgeted variable overheads are ₹2,00,000 for 10,000 labour hours, and budgeted fixed overheads are ₹3,00,000 for 10,000 labour hours. Prepare the standard cost per unit.

Show the solution

Standard input of material = 10 ÷ (1 − 0.20) = 10 ÷ 0.8 = 12.5 kg.
Standard material cost = 12.5 × ₹60 = ₹750.
Standard labour cost = 4 × ₹50 = ₹200.
Variable overhead rate = ₹2,00,000 ÷ 10,000 = ₹20 per hour. Per unit = 4 × ₹20 = ₹80.
Fixed overhead rate = ₹3,00,000 ÷ 10,000 = ₹30 per hour. Per unit = 4 × ₹30 = ₹120.
Total = 750 + 200 + 80 + 120 = ₹1,150.

Answer: Standard cost per unit = ₹1,150.

Example 2

Explain the four types of standards used in standard costing and state which is best for cost control.

Show the solution

Ideal standard: set for perfect conditions with no waste, idle time or breakdowns. It is rarely achieved and may discourage staff.
Basic standard: fixed for a long period and not changed with prices or methods. It is used as a base for measuring trends.
Normal standard: based on average performance expected over a business cycle, covering seasonal and cyclical swings.
Current standard: based on present operating conditions and attainable with reasonable effort. It allows normal loss and idle time.
Conclusion: current standards are the most useful for control because staff accept them and variances show real inefficiency.

Answer: Ideal, basic, normal and current standards differ in the conditions assumed; the current (attainable) standard is best for day-to-day cost control.

Exam tips

In theory answers, write each type of standard as a separate point with a one-line definition; this earns step marks.
For MCQs, link keywords: 'perfect conditions' means ideal, 'not revised' means basic, 'present conditions' means current, 'average over cycle' means normal.
In setting-standard problems, always show normal loss working separately before pricing material.
For the comparison question, give at least four points of difference in a two-column style written as lines, with a heading for each.
Show the overhead rate calculation on its own line; examiners award marks for the rate even if later arithmetic slips.

Standard Costing: Concepts and Setting Standards: frequently asked questions

What is standard costing in simple words?

It is a method where you fix what a unit should cost before production, then compare it with what it actually cost. The difference is a variance, and you study its cause to control cost.

What is the difference between standard costing and budgetary control?

Standard costing sets cost per unit and focuses on cost control through variances. Budgetary control sets total targets for a period across functions and compares actual results with them. Standards are scientific and unit-based; budgets are plans for overall activity.

Which type of standard is best?

The current or attainable standard is usually best for control. It reflects present conditions and can be reached with reasonable effort, so it motivates staff and gives meaningful variances.

How is standard cost different from estimated cost?

Estimated cost is a forecast, often based on past data, of what a cost is likely to be. Standard cost is a carefully set target of what the cost ought to be, and it is used as a yardstick for control.
