Budgets and Variance Analysis
A budget is a plan with numbers attached. A variance is the gap between that plan and what actually happened. The calculation takes seconds; the interesting part is working out why the gap appeared and what the business should do next.
What you need to know
A budget is a financial plan of expected costs and revenue for a set period, agreed in advance.
Budgets are set for the whole firm and for each cost centre or profit centre.
The master budget pulls all the delegated budgets together into one plan.
A variance is the difference between a budgeted figure and the actual figure.
Favourable (F) means the actual result is better than planned. Adverse (A) means worse.
For revenue and profit, higher is favourable. For costs, lower is favourable. That flip is the whole trick.
Why businesses budget
Reason
What it does in practice
Planning
Forces the firm to think ahead and spot problems before they arrive
Control
Regular monitoring means a manager can see overspending early and act
Coordination
Departments have to work as one whole, since their budgets connect
Motivation
A clear target to aim at, plus the responsibility of holding a budget
Efficiency
Senior managers are freed up because they do not approve every small decision
Two ways to build a budget
Historical budgeting. Start from last year’s figures and adjust for inflation, exchange rates and expected growth. Quick, familiar, and by far the most common. The weakness is that it carries last year’s waste forward without questioning it.
Zero-based budgeting. Every department starts at zero and must justify every dollar it wants. Nothing is assumed. It controls costs tightly but takes a lot of time, and it needs confident staff who can argue their case.
Zero-based budgeting is a great answer when a case study firm has rising costs and no idea where the money is going. It is a poor answer for a busy firm with no spare management time.
The master budget
Individual budgets are delegated to the departments that will spend them. The finance director then consolidates all of them into the master budget, which is the firm’s overall financial plan.
Change one delegated budget and the master budget changes with it, which is why negotiation between departments matters.
What shapes the numbers
Historical data. Last year’s performance is the usual starting point.
Availability of finance. A profitable firm, or one that can borrow, can afford a more generous budget.
Benchmarking. If a close rival raises its advertising spend, the marketing budget often follows.
Negotiation. Budget holders argue their case with the finance team, and departments compete for the same pot.
Favourable and adverse variances
This is the part students get wrong under pressure. The words favourable and adverse do not mean higher and lower — they mean better and worse. Whether higher is better depends on whether you are looking at revenue or costs.
Sketch this four-box grid in the margin before you label any variance. It takes ten seconds and stops the classic error.
Examples of favourable variances: actual wages below budget, sales volume above budget, raw material spending below budget. Adverse: fuel costs above budget, profit below budget, marketing spend above budget.
WORKED EXAMPLE
Total profit variance
Kabir Cycles budgeted for revenue of $840,000 and total costs of $610,000. Actual revenue was $802,000 and actual costs were $588,000. Calculate the total profit variance and state whether it is favourable or adverse. [4]
Step 1: budgeted profit840,000 − 610,000 = $230,000Step 2: actual profit802,000 − 588,000 = $214,000Step 3: compare actual with budget214,000 − 230,000 = −$16,000Step 4: label it$16,000 adverse (A)Look underneath the total. Costs were $22,000 favourable, but revenue was $38,000 adverse. The cost saving was real, and it still was not enough to rescue the profit.
Always break a total variance into its parts if the data lets you. “Profit missed by $16,000” is a fact. “Sales fell short by $38,000 and only tight cost control kept the gap to $16,000” is analysis.
Responding to variances
Variance found
Sensible response
Adverse cost variance
Look for alternative suppliers or investigate where efficiency is being lost
Adverse sales variance
Review the marketing, the pricing and whether the target was realistic
Favourable cost variance
Check quality has not slipped — returns, waste levels and complaints
Favourable sales variance
Recognise and reward the staff involved, and check stock can keep up
Adverse is not automatically bad. If demand jumped unexpectedly, the firm may have paid overtime, bought extra stock and spent more on delivery. Those adverse cost variances came from a good problem.
Difficulties with budgeting
Budgets are only as good as the data. Inaccurate or biased figures make the whole exercise pointless.
They take time and skill to set, monitor and review, which is a real cost for a small firm.
They encourage short-term thinking, because they are usually set year by year.
They cause conflict between departments competing for the same money.
Unrealistic targets damage motivation. A target nobody can hit stops being a target.
Budget setters have real power over which parts of the firm can grow.
How to answer a variance question
Work out budgeted profit and actual profit separately.
Subtract budgeted from actual, and keep the sign.
Label it F or A using the four-box grid.
Split the total into its revenue and cost parts if you can.
Explain the cause using the case study, then recommend one action.
Exam tip
Always write F or A after the number. A bare figure is an incomplete answer.
Show budgeted profit and actual profit as separate lines — each is usually worth a mark.
Never call a cost variance adverse just because the number went down.
Use the case study to explain the cause. Examiners reward the reason, not the arithmetic.
Remember variances can come from outside the firm: exchange rates, fuel prices, a recession.
When you evaluate a budgeting system, weigh better control against conflict, time and short-termism.
Common mix-up
Calling a lower cost figure adverse. Spending less than planned is favourable.
Mixing up the subtraction order. Actual minus budget, every time, then label the result.
Treating a budget as a forecast. A forecast predicts; a budget is a target the firm commits to.
Blaming the manager for every adverse variance. Many causes are external.
Ignoring favourable variances. They can hide cut corners or an unambitious target.
Confusing zero-based with historical budgeting. One starts from nothing, the other from last year.
