Variance analysis

Variance Analysis is the process of studying the differences between what a business planned and what actually happened. It helps companies understand where money, time, or resources went off track—or performed better than expected. By comparing budgets or standard costs to actual results, variance analysis gives management the insight needed to correct problems quickly and make smarter financial decisions.

In simple terms, it’s the comparison between what was expected (budgeted) and what was achieved (actual). The difference between the two is known as a variance.
Formula:

Variance = Actual − Budget (or Actual − Standard)

If actual results exceed the plan in a way that hurts performance, it’s an unfavourable variance. If results are better than planned—like lower costs or higher sales—it’s a favourable variance.

What Variance Analysis Means in Simple Terms

Variance Analysis compares planned performance against actual results to identify gaps.
It’s a key tool for managers to monitor efficiency, cost control, and profitability.

Key Terms You Should Know

  • Budget: The financial or operational plan.

  • Standard: The benchmark for cost, time, or quantity.

  • Actual: The real performance or cost incurred.

  • Favourable (F): Actual performance is better than the plan.

  • Unfavourable (U): Actual performance is worse than the plan.

  • Price (Rate) Variance: Difference between the price paid and price planned.

  • Quantity (Usage/Efficiency) Variance: Difference between the amount used and the amount planned.

  • Volume Variance: Difference between actual and planned sales or production output.

The Five Steps of Variance Analysis

  1. Set the Plan: Define the budget or standard.

  2. Record Actual Results: Gather real data from operations.

  3. Calculate the Variance: Find the difference between actual and planned figures.

  4. Break Down the Variance: Identify whether it’s due to price, quantity, rate, or time.

  5. Find the Cause and Act: Investigate the reason and take corrective action.

Main Types of Variances

  • Material Variance: Price and usage differences in materials.

  • Labour Variance: Rate and efficiency differences in workforce costs.

  • Overhead Variance: Variable and fixed overhead deviations.

  • Sales Variance: Differences in price and sales volume.

How to Calculate Variances  Formulas and Rules

Cost Variance Formulas

  • Price (Rate) Variance = (Actual Price − Standard Price) × Actual Quantity

  • Quantity (Usage) Variance = (Actual Quantity − Standard Quantity) × Standard Price

Sales Variance Formulas

  • Sales Price Variance = (Actual Price − Budget Price) × Actual Units Sold

  • Sales Volume Variance = (Actual Units − Budget Units) × Budget Price

Rules:

  • For costs, a positive variance means unfavourable (spent more than planned).

  • For sales, a positive variance means favourable (earned more than planned).

Variance Analysis Examples

Example 1: Material Variance

A shop makes 100 toy chairs.

  • Standard: 2 kg per chair at $5.00 per kg → 200 kg total = $1,000 standard cost.

  • Actual: 220 kg used at $4.80 per kg → $1,056 actual cost.

Calculations:

  • Material Price Variance: (4.80 − 5.00) × 220 = −$44 → $44 Favourable

  • Material Quantity Variance: (220 − 200) × 5.00 = $100 → $100 Unfavourable

  • Net Variance: −44 + 100 = $56 Unfavourable

Meaning: Saved on price, but used more material. Investigate causes like waste or poor cuts.

Example 2: Labour Variance

A factory produces 100 units.

  • Standard: 1.5 hours per unit at $10/hour → 150 hours = $1,500 standard cost.

  • Actual: 140 hours worked at $11/hour → $1,540 actual cost.

Calculations:

  • Rate Variance: (11 − 10) × 140 = $140 Unfavourable

  • Efficiency Variance: (140 − 150) × 10 = −$100 → $100 Favourable

  • Net Variance: +140 −100 = $40 Unfavourable

Meaning: Workers were faster but paid more. The trade-off slightly increased cost.

Example 3: Sales Variance

Budget: 1,000 units at $20 → $20,000.
Actual: 1,200 units at $18 → $21,600.

Calculations:

  • Sales Price Variance: (18 − 20) × 1,200 = −$2,400 → Unfavourable

  • Sales Volume Variance: (1,200 − 1,000) × 20 = +$4,000 → Favourable

  • Net Variance: +$1,600 Favourable

Meaning: Sold more at a lower price. Check if higher volume offsets lower margins.

Example 4: Overhead Variance

  • Standard Variable Overhead Rate = $2/hour

  • Standard Hours = 150; Actual Hours = 140

  • Actual Variable Overhead = $320

  • Budgeted Fixed Overhead = $1,000

Calculations:

  • Variable Overhead Spending Variance: 320 − (140 × 2) = $40 Unfavourable

  • Variable Overhead Efficiency Variance: (140 − 150) × 2 = −$20 → $20 Favourable

  • Fixed Overhead Volume Variance: (150 − 140) × 6.67 = $66.67 Unfavourable

Meaning: Slightly higher variable costs and lower production increased total cost.

In summary, Variance Analysis is more than just a calculation it’s a management tool for continuous improvement. By identifying where performance deviates from plans, businesses can take early corrective action, control costs, and boost profitability.

The key is not just computing the numbers but interpreting why those differences occur and how to fix them. Whether it’s material wastage, labour inefficiency, or pricing issues, understanding variances helps managers make smarter, data-driven decisions.
