Classification of Budgets in Cost Accounting

Updated 10 October 2026 · Fact-checked

Classification of budgets means grouping budgets by a common basis. The main bases are function (functional and master), time (long-term and short-term), flexibility (fixed and flexible) and capacity (normal, full or partial). To answer, name the basis first, then the type, its meaning and a short example.

Understand Classification of Budgets

A budget is a financial or quantitative plan for a future period, prepared in advance and approved by management. Because firms plan for different purposes, budgets are grouped in different ways. Each grouping answers one question.

By function: which part of the business is planned? A functional budget covers one function, such as sales, production, purchase, cash or capital expenditure. The master budget combines all functional budgets into one summary plan. It is usually shown as a budgeted profit and loss account and balance sheet, and it is approved by top management.

By time: how far ahead does the plan look? A long-term budget covers a number of years, often for capital expenditure, product development or expansion. A short-term budget usually covers a year or less and is broken into months or quarters. Some books add a current budget, which covers a very short period and is tied to present conditions.

By flexibility: does the budget change with activity? A fixed budget is prepared for one level of activity and is not adjusted even if actual activity differs. A flexible budget is prepared for several activity levels, or recast to the actual level, so that actual cost is compared with the budget allowed for that same level.

By capacity: which capacity is assumed? Budgets can be based on normal, full or partial capacity. Related labels such as basic budget (a long-term standard) or zero base budget are covered under their own topics. Always state the basis you are using when classifying.

Key rules to remember

Classification by function
Functional budgets (sales, production, purchase, cash, capital expenditure) → combined into the Master budget
The master budget is the summary of all functional budgets, not another functional budget.
Classification by time
Long-term (several years) | Short-term (up to about one year) | Current (very short period)
Long-term budgets are usually in physical or broad terms; short-term ones are detailed in money.
Classification by flexibility
Fixed budget = one activity level | Flexible budget = several activity levels
A flexible budget separates fixed and variable costs. Variable cost moves with activity; fixed cost stays constant within the relevant range.
Flexed budget cost
Budget allowed = Fixed cost + (Variable cost per unit × Actual units)
Use this to compare actual cost with the budget at actual activity.
Capacity basis
Budgets may assume normal, full or partial capacity
State the capacity assumed; it changes the fixed cost per unit.

How to solve Classification of Budgets questions

Use this method for both theory questions and short numerical questions on types of budgets.

  1. 1Read the question and identify the basis of classification asked: function, time, flexibility or capacity.
  2. 2Name each type under that basis and give a one-line definition in your own words.
  3. 3Add a short business example, such as a Pune auto-parts maker preparing a sales budget.
  4. 4For a difference question, write points side by side: meaning, activity level, cost behaviour, comparison use and suitability.
  5. 5For a numerical question, split costs into fixed and variable and compute the budget for the required activity level.
  6. 6Compare actual cost with the flexed budget, not the original fixed budget, and label each difference favourable or adverse.
  7. 7Close with one line on usefulness, for example that flexible budgets suit firms with changing demand.

Quickest way: Basis-first memory grid

When to use it: Use this for MCQs and for the opening lines of a descriptive answer.

  1. Write four labels: Function, Time, Flexibility, Capacity.
  2. Attach the types: Functional/Master, Long/Short term, Fixed/Flexible, Normal/Full/Partial.
  3. If the option says one activity level only, choose fixed. If it says changes with activity, choose flexible.
  4. If the option says combines all functional budgets, choose master.
  5. In a numerical, compute flexed cost first: fixed + variable per unit × units.

Common mistakes in Classification of Budgets

  • Calling the master budget a functional budget.

    Both words sound like parts of the same plan.

    Fix: Remember that functional budgets are the parts and the master budget is the combined whole.

  • Comparing actual cost with a fixed budget at a different activity level.

    Students use the original budget figure without adjusting it.

    Fix: Flex the budget to actual activity before finding variances.

  • Treating fixed cost as changing in total in a flexible budget.

    The word flexible suggests every cost moves.

    Fix: Only variable cost changes in total. Fixed cost stays constant within the relevant range.

  • Mixing up bases, such as listing long-term budgets as a type of functional budget.

    Students memorise names without the basis.

    Fix: Always write the basis as a heading before listing types.

  • Saying a fixed budget is useless.

    Textbooks stress its limits.

    Fix: Say it suits stable conditions or fixed-output activities, but is unreliable when actual activity varies.

Worked examples

Example 1

Distinguish between a fixed budget and a flexible budget (five points).

Show the solution
  1. Meaning: a fixed budget is prepared for one expected activity level; a flexible budget is prepared for a range of activity levels or adjusted to actual activity.
  2. Cost behaviour: a fixed budget does not separate costs by behaviour; a flexible budget separates fixed and variable costs.
  3. Adjustment: a fixed budget is not changed when actual activity differs; a flexible budget is recast.
  4. Comparison: a fixed budget gives a poor comparison if activity differs; a flexible budget compares like with like.
  5. Suitability: a fixed budget suits stable conditions; a flexible budget suits changing demand.

Answer: A fixed budget is rigid and set for one activity level, while a flexible budget changes with activity and gives a fair basis for control.

Example 2

Ganga Textiles budgeted for 10,000 units: variable cost ₹40 per unit and fixed cost ₹2,00,000. Actual output was 12,000 units and actual total cost was ₹6,95,000. Find the flexed budget cost and the variance.

Show the solution
  1. Original fixed budget cost = 2,00,000 + (40 × 10,000) = 2,00,000 + 4,00,000 = ₹6,00,000.
  2. Flexed variable cost = 40 × 12,000 = ₹4,80,000.
  3. Fixed cost stays at ₹2,00,000.
  4. Flexed budget cost = 4,80,000 + 2,00,000 = ₹6,80,000.
  5. Variance = actual 6,95,000 − flexed 6,80,000 = ₹15,000, which is adverse because actual cost is higher.
  6. Against the fixed budget the gap would show ₹95,000 adverse, which is misleading.

Answer: Flexed budget cost is ₹6,80,000; the true variance is ₹15,000 adverse.

Exam tips

  • In MCQs, first spot the basis in the stem: one activity level, many levels, whole business, or time span.
  • For difference questions, write at least four points in two columns; step marks follow clear points.
  • Always flex before comparing in numericals, and mark each variance as favourable or adverse.
  • Give a short example with every type; it shows understanding and fills a 14-mark answer.

Classification of Budgets: frequently asked questions

What is the difference between a fixed budget and a flexible budget?

A fixed budget is made for one activity level and is not changed. A flexible budget is made for several levels or adjusted to actual activity. Flexible budgets give better control because actual cost is compared with the budget at the same activity.

What is the difference between functional and master budgets?

A functional budget covers one function, such as sales or production. The master budget combines all functional budgets into one overall plan, often as a budgeted profit and loss account and balance sheet.

What are the main bases for classifying budgets?

The main bases are function, time, flexibility and capacity. Each basis has its own types, so name the basis before you list the types.

Is a long-term budget the same as a master budget?

No. Long-term describes the time span, while master describes the combined nature of the plan. A master budget is usually prepared for the short term.
