Introduction to Standard Costing for CA Intermediate
Updated 4 October 2026 · Fact-checked
Standard costing is a technique where you fix a predetermined cost for a unit of output, compare it with the actual cost, and analyse the differences (variances) to control cost. To answer questions, define the standard, set it for material, labour and overheads, then compare with actuals.
Understand Introduction to Standard Costing
A standard cost is a carefully predetermined cost of a product or service, worked out from expected quantities and expected prices under stated operating conditions. It tells you what a unit should cost, not what it did cost.
Standard costing is the technique of setting such standards, measuring actual cost, finding the difference (variance), and finding the reasons for it so that management can act. Without a standard, an actual cost of ₹50 a unit means nothing. With a standard of ₹45, you know there is an adverse gap of ₹5 to explain.
The main objectives are: to act as a yardstick for measuring efficiency, to control cost through variance analysis, to help in budgeting and price fixing, to apply management by exception, to value stock and work-in-progress at simple standard rates, and to motivate staff by giving clear targets.
There are different types of standards. An ideal standard assumes perfect conditions with no waste, idle time or breakdown. It is hard to reach and can demotivate. A normal standard is based on average past performance expected over a long period, such as a trade cycle. A current standard is based on present conditions and is set for a short period. A basic (bases) standard is fixed for a long time and not revised, so it works as an index base for comparing trends. An attainable (expected) standard is a tight but achievable target with normal allowance for waste and delay. It is the one most used in practice.
Standards are set for each element. For material you fix standard quantity (from product design, specification and allowance for normal loss) and standard price (from purchase quotations, market trends, and the pricing policy). For labour you fix standard time (from time and motion study, with allowance for fatigue and normal idle time) and standard rate (from wage agreements and policy). For overheads you fix the standard overhead rate as budgeted overhead divided by budgeted base (hours or units). Standards are revised when conditions change, such as a new process, price shifts or wage settlements, not for every small deviation.
Key rules to remember
- Standard cost of an element
- Standard cost = Standard quantity (or time) × Standard price (or rate)
- Applies to material and labour. Quantity is for actual output, adjusted for normal loss.
- Standard overhead rate
- Standard overhead rate = Budgeted overhead ÷ Budgeted base (units or hours)
- Compute separately for variable and fixed overheads when asked.
- Variance
- Variance = Standard cost for actual output − Actual cost
- For cost items, a positive result is favourable and a negative result is adverse. Always state F or A.
- Standard cost of one unit
- Standard cost per unit = Material + Labour + Variable overhead + Fixed overhead (per unit)
- Prepared as a standard cost card.
How to solve Introduction to Standard Costing questions
Theory questions on this topic ask for meaning, objectives, types, merits, limits or the setting of standards. Use the same structure each time.
- 1Read the verb: define, explain, distinguish, state or discuss. This decides your length and format.
- 2Start with a one-line definition of standard cost or standard costing in your own words.
- 3List points in order with a bold keyword for each, such as the objective or type, followed by one line of explanation.
- 4Add a short example with numbers where it helps, for instance a standard cost card.
- 5For distinction questions, use clear parallel points such as basis, purpose, scope, period and use of variances.
- 6For setting standards, cover each element in turn: material quantity and price, labour time and rate, overhead rate.
- 7Close with a one-line conclusion linking standards to variance analysis and management by exception.
Quickest way: Keyword-and-pairs method
When to use it: Use it for MCQs and for short written answers when time is tight.
- For MCQs, match the key phrase: no waste or idle time means ideal; average of past performance means normal; fixed for long period means basic; tight but achievable means attainable.
- If an option says standard costing needs no revision or suits every business, eliminate it as an overstatement.
- For written answers, write a heading line, then 4 to 6 numbered points with a bold keyword in each. Examiners award marks per point.
- For setting standards, remember the pairs: quantity and price, time and rate, budgeted overhead and budgeted base.
- For advantages and limitations, give at least three of each. Mention management by exception under advantages and costly, frequent revision under limitations.
Common mistakes in Introduction to Standard Costing
Treating ideal and attainable standards as the same.
Both are described as targets, so the difference in conditions gets missed.
Fix: Remember ideal assumes perfect conditions with no loss. Attainable allows normal waste, idle time and delays.
Saying standard costing and budgetary control are identical.
Both use predetermined figures and comparison with actuals.
Fix: State the difference: standards are unit-level cost targets for a product or operation, while budgets are total-level plans for a function or the whole business over a period. Standards are used mainly for cost control, budgets for overall planning and control of expenses and revenue.
Listing advantages only and forgetting limitations.
Students find advantages easier to recall.
Fix: Write at least three limitations: costly to install and maintain, needs revision in changing conditions, and difficult in firms with non-standard products or jobs.
Revising standards after every variance.
Students assume adverse variances mean the standard is wrong.
Fix: Revise only when there is a lasting change, such as a new process, permanent price change or new wage agreement. Otherwise investigate the variance.
Setting the material standard quantity without normal loss.
Students use only the finished output quantity.
Fix: Standard input equals output plus allowance for normal loss. Abnormal loss is not part of the standard.
Ignoring the direction of a variance in the answer.
Students calculate the number and stop.
Fix: Always label each variance as favourable (F) or adverse (A) and say what it signals.
Worked examples
Example 1
A company makes one unit of a product using 4 kg of material at a standard price of ₹50 per kg and 3 labour hours at a standard rate of ₹80 per hour. Budgeted fixed overhead is ₹1,20,000 for 6,000 labour hours. Prepare the standard cost per unit, and the standard cost for 500 units.
Show the solution
- Material: 4 kg × ₹50 = ₹200.
- Labour: 3 hours × ₹80 = ₹240.
- Fixed overhead rate: ₹1,20,000 ÷ 6,000 hours = ₹20 per hour.
- Fixed overhead per unit: 3 hours × ₹20 = ₹60.
- Standard cost per unit: ₹200 + ₹240 + ₹60 = ₹500.
- Standard cost for 500 units: 500 × ₹500 = ₹2,50,000.
Answer: Standard cost per unit is ₹500. For 500 units it is ₹2,50,000.
Example 2
Standard cost of a product is ₹500 per unit. In a month 500 units were made at an actual cost of ₹2,60,000. Find the total cost variance and state what the management should do. Also name the type of standard best suited if management wants a tight but achievable target.
Show the solution
- Standard cost for actual output: 500 × ₹500 = ₹2,50,000.
- Actual cost: ₹2,60,000.
- Variance: ₹2,50,000 − ₹2,60,000 = ₹10,000, which is negative, so it is adverse.
- Percentage of standard: ₹10,000 ÷ ₹2,50,000 = 4%.
- Under management by exception, management should find the cause by element (material, labour, overhead) and decide whether it is controllable.
- For a tight but achievable target, the suitable type is the attainable (expected) standard.
Answer: Total cost variance is ₹10,000 adverse (4% of standard cost). Investigate it element by element. Attainable standard suits the stated need.
Exam tips
- For a long theory question, write numbered points with bold keywords. Examiners give marks per point, so use clear headings you can scan.
- Learn the four types of standards with one trigger phrase each. MCQs usually test these phrases.
- Practise the standard cost card. Quantity × price and time × rate are the base of all later variance work.
- In distinction questions, use at least four parallel points and keep them in the same order on both sides.
- Since there is no negative marking, attempt every MCQ. Eliminate overstatements such as always or never first.

Introduction to Standard Costing: frequently asked questions
What is the meaning of standard costing in simple words?
It is a technique where you decide in advance what a unit should cost, compare it with what it actually cost, and study the difference. The difference is called variance. Management then acts on the variances that matter.
What is the difference between standard costing and budgetary control?
Standard costing sets unit-level cost targets and mainly controls cost through variances. Budgetary control sets total-level targets for functions or the whole business for a period and covers revenue as well as expenses. They work well together, but they are not the same.
Which type of standard is most used in practice?
The attainable or expected standard is most used, as it is tight enough to push efficiency but realistic enough to be reached. Ideal standards are rarely used for this reason. Current standards are common for short periods.
When should standards be revised?
Revise them when there is a lasting change, such as new methods, new machinery, a permanent change in material prices or a new wage agreement. Do not change them for a one-off variance. Frequent changes weaken the use of standards as a yardstick.
