Standard Costing and Variance Analysis Basics for CMA Final

Updated 11 October 2026 · Fact-checked

Standard costing sets a predetermined cost for each unit of output, compares it with the actual cost, and explains the difference as variances. A variance is favourable if it raises profit and adverse if it lowers profit. To solve questions, compute standard, compute actual, find the difference, and label its nature.

Understand Standard Costing and Variance Analysis Basics

Standard costing is a technique where you fix a predetermined cost for material, labour and overheads for one unit of output under stated conditions. You then record the actual cost and compare the two. The gap is a variance. The aim is control, not just calculation.

A standard is a carefully prepared estimate of what a cost should be. It is built from technical studies, past data, current prices and expected efficiency. The same standard is used for costing output, pricing, valuing stock and judging performance.

Standards differ by how tight they are. An ideal standard assumes perfect conditions with no waste, idle time or breakdown. A normal standard reflects the average level over a long period, including a business cycle. An expected (attainable) standard is what you can reach with efficient but realistic working, allowing for normal losses. A basic standard is fixed for a long time and not revised, so it serves as a base for index comparison. A current standard is set for a short period and is tied to present conditions.

A variance is favourable (F) when actual results are better than standard: lower cost or higher revenue or profit. It is adverse (A) when actual results are worse: higher cost or lower profit. For sales, direction depends on the effect on profit, not on whether the number is bigger or smaller.

Variances are classified in several ways. By element: material, labour, overhead and sales. By controllability: controllable (management can influence, such as usage) and uncontrollable (such as a government price hike). By nature: price/rate/expenditure variances and quantity/efficiency/volume variances. Standard costing is not the same as budgetary control, as the formulas and tips below show.

Key rules to remember

General variance rule (cost): Cost variance = Standard cost for actual output − Actual cost; Positive means Favourable, negative means Adverse. Always use standard for actual output, not budgeted output.
General variance rule (sales/profit): Sales or profit variance = Actual − Standard (or budgeted); Positive means Favourable, negative means Adverse. The sign convention is reversed from cost.
Price-type variance: (Standard price − Actual price) × Actual quantity; Applies to material price, labour rate and overhead expenditure style variances.
Quantity-type variance: (Standard quantity for actual output − Actual quantity) × Standard price; Applies to material usage and labour efficiency. Valued at standard price.
Standard cost of a unit: Standard cost = Standard quantity × Standard price (for each element), summed; Prepare a standard cost card for material, labour, variable and fixed overheads.
Standard cost for actual output: Standard cost for actual output = Standard cost per unit × Actual units produced; This is the flexed standard used for comparison.

How to solve Standard Costing and Variance Analysis Basics questions

Use this order for any basic standard costing or variance question.

1Read what is asked: concept, standard-setting, or a numerical variance with its nature.
2Write the standard cost card per unit: quantity, price and cost for each element.
3Find actual output and scale the standard: standard quantity for actual output = standard per unit × actual units.
4Write the actual quantity, price and cost for each element from the data.
5Apply the cost rule: standard minus actual. Compute price and quantity parts separately if asked.
6Label every answer F or A. Positive in a cost variance is F; negative is A.
7Check that the parts add up to the total variance, then add a short comment on cause and responsible person.

Quickest way: Standard minus actual, then label

When to use it: Use for MCQs and for short numerical parts where only the variance and its nature are needed.

Ask: did actual cost more than it should have? If yes, it is Adverse; if less, Favourable.
For price: compare the two prices and multiply by actual quantity.
For quantity: compare actual quantity with standard quantity for actual output and multiply by standard price.
Do the sign check by logic, not by arithmetic. Paying more or using more is Adverse.
For concept MCQs, recall the standard types: ideal, normal, expected, basic, current.

Common mistakes in Standard Costing and Variance Analysis Basics

Comparing actual cost with standard cost of budgeted output
Students use the original budget figures because they are given first.
Fix: Always flex the standard to actual output before comparing.
Marking a variance F or A by the sign of the number alone
The rule differs for costs and for sales or profit.
Fix: Ask whether profit rises or falls. Higher cost is A; higher sales or profit is F.
Valuing the quantity variance at actual price
Students mix the price and quantity parts.
Fix: Price variance uses actual quantity; quantity variance uses standard price.
Treating ideal and expected standards as the same
Both are called targets.
Fix: Ideal assumes no losses at all. Expected allows normal wastage and idle time, so it is attainable.
Confusing standard costing with budgetary control
Both use predetermined figures and variances.
Fix: Standards are unit-level cost figures; budgets are total-level plans for a function or period. Standard costing is a cost-control technique for output; budgetary control is a wider control of income and expense.
Stopping at the number without a comment
Students think the calculation is the whole answer.
Fix: Add one line on likely cause and who is responsible, since written answers reward interpretation.

Worked examples

Example 1

Standard material for one unit of Product P is 4 kg at ₹50 per kg. In a month, 1,000 units were produced and 4,200 kg were used at ₹48 per kg. Find the material price variance, usage variance and total material cost variance with their nature.

Show the solution

Standard quantity for actual output = 1,000 × 4 = 4,000 kg.
Standard cost for actual output = 4,000 × ₹50 = ₹2,00,000.
Actual cost = 4,200 × ₹48 = ₹2,01,600.
Price variance = (₹50 − ₹48) × 4,200 = ₹8,400 F.
Usage variance = (4,000 − 4,200) × ₹50 = ₹10,000 A.
Total variance = ₹2,00,000 − ₹2,01,600 = ₹1,600 A.
Check: ₹8,400 F + ₹10,000 A = ₹1,600 A.

Answer: Price variance ₹8,400 F; usage variance ₹10,000 A; total material cost variance ₹1,600 A.

Example 2

A manager says: 'We will set a standard that needs no wastage and no idle time, so staff aim for perfection.' Name this standard, state one drawback, and say which standard would be better for cost control and for stock valuation.

Show the solution

A standard assuming no wastage, idle time or breakdown is an ideal standard.
Drawback: it is almost never achieved, so variances are always adverse and staff may lose motivation.
The measure used for cost control and valuation should be attainable, so use an expected standard that allows for normal losses.
Expected standards give variances that point to real inefficiency, so action can be targeted.

Answer: The standard is an ideal standard. Its drawback is that it is unattainable and demotivating. An expected (attainable) standard is better for control and stock valuation.

Exam tips

Practise the F/A label until it is automatic. Many marks in MCQs are lost on direction, not calculation.
For theory answers, list the types of standards with a one-line distinction each, then add attainability and motivation.
In a case-based question, state the standard cost card first. It anchors every later variance.
Write a short interpretation for each variance in descriptive questions, naming the likely cause and the responsible manager.
When asked to differentiate standard costing and budgetary control, use points like unit versus total level, cost versus overall plan, and use for pricing and valuation.

Standard Costing and Variance Analysis Basics: frequently asked questions

What are the types of standards in standard costing?

The main types are ideal, normal, expected (attainable), basic and current standards. They differ in how demanding they are and how long they stay fixed. Expected standards are the most useful for day-to-day control.

What is the difference between standard costing and budgetary control?

Standard costing sets cost per unit and analyses variances by cost element. Budgetary control sets targets in total for departments or periods and compares actual with budget. Standards are used for costing and valuation as well, while budgets focus on planning and control of income and expenditure.

How do you set cost standards?

You study the product and process to fix material quantities, labour hours and overhead allocation. Prices and rates come from supplier quotes, wage agreements and budgeted overheads. You then record these on a standard cost card and revise them when conditions change.

How do I know if a variance is favourable or adverse?

Ask what the variance does to profit. If it increases profit, it is favourable; if it reduces profit, it is adverse. For costs, spending less than standard is favourable; for sales, selling more or at a higher price is favourable.
