## AQA A-Level Accounting (7127) Syllabus

For the AQA A-Level Accounting (7127), you are expected to understand sales variances within standard costing and variance analysis, with a focus on the following syllabus points:

- Know that a variance is the difference between standard cost or revenue and actual cost or revenue
- Calculate **sales price variance** using actual quantity sold and the difference between actual and standard selling price
- Calculate **sales volume variance** and identify whether the question requires a revenue basis or a contribution basis
- Identify whether a sales variance is **favourable** or **adverse**
- Derive the **actual selling price per unit** from actual revenue and actual units sold when needed
- Use sales variances in a **sales reconciliation statement** from budgeted revenue to actual revenue
- Explain likely causes of sales variances without confusing revenue effects with profit effects
- Understand that a favourable sales volume variance does not always mean higher overall profit

## Test Your Knowledge

_Attempt these questions before reading this article. If you find some difficult or cannot remember the answers, look more closely at that area during your revision._

1. What is the formula for **sales price variance**?
2. Why does sales price variance use **actual quantity sold** rather than budgeted quantity?
3. How do you calculate **sales volume variance** on a revenue basis?
4. If actual revenue and actual units are given, how do you find the actual selling price?
5. Why might a favourable sales volume variance fail to improve profit as much as expected?

## Introduction

Sales variances are part of standard costing and variance analysis. They help a business compare what it expected to earn from sales with what it actually earned. In AQA A-Level Accounting, this is a high-value topic because it combines calculation skill with interpretation.

You need to be precise. Students often get the arithmetic right but use the wrong formula basis, or they identify a variance as favourable or adverse incorrectly. The safest approach is to know exactly what each variance isolates: **price** isolates the effect of charging a different selling price, while **volume** isolates the effect of selling a different quantity.

> **Key Term: sales variance**
> The difference between standard sales revenue and actual sales revenue.

### What sales variances measure

Sales variances analyse the difference between budgeted and actual sales performance. The overall sales variance can be split into two parts:

- **sales volume variance**
- **sales price variance**

This split matters because the causes are different. A sales manager may explain a lower selling price through discounting or competitive pressure, while a lower sales volume may be linked to weak demand, supply issues, or poor promotion.

> **Key Term: favourable variance**
> A variance that improves the result compared with the standard or budget.
>
> **Key Term: adverse variance**
> A variance that worsens the result compared with the standard or budget.

For sales, the logic is straightforward:

- **higher revenue than expected** is favourable
- **lower revenue than expected** is adverse

So:

- if actual selling price is above standard selling price, the **sales price variance** is favourable
- if actual selling price is below standard selling price, the **sales price variance** is adverse
- if actual quantity sold is above budgeted quantity, the **sales volume variance** is favourable
- if actual quantity sold is below budgeted quantity, the **sales volume variance** is adverse
  > **Test Tip:** In a sales variance question, write F or A only after checking the business effect. Higher sales price or higher quantity is favourable. Lower sales price or lower quantity is adverse.

### Sales price variance

Sales price variance measures the effect of selling at a different price from the standard price.

Formula:

$$
\text{Sales price variance} = (\text{Actual selling price} - \text{Standard selling price}) \times \text{Actual quantity sold}
$$

This can also be seen as:

$$
\text{Actual revenue} - (\text{Actual quantity sold} \times \text{Standard price})
$$

The use of **actual quantity sold** is important. The price difference only applies to the units actually sold, not the units that were budgeted.

> **Key Term: sales price variance**
> The sales revenue difference caused by the actual selling price being different from the standard selling price.

#### Worked example: sales price variance

A business budgeted to sell a product at **£26** per unit. It actually sold **8,600 units** for total revenue of **£219,300**.

Step 1: Calculate actual selling price per unit

$$
\text{Actual selling price} = \frac{£219,300}{8,600} = £25.50
$$

Step 2: Apply the formula

$$
\text{Sales price variance} = (£25.50 - £26.00) \times 8,600
$$

$$
= (-£0.50) \times 8,600
$$

$$
= -£4,300
$$

So the sales price variance is **£4,300 adverse**.

Reason: the business sold each unit for **50p less** than standard.

#### Common student errors

- using **budgeted quantity** instead of **actual quantity**
- forgetting to calculate actual selling price from revenue and units
- writing £4,300 favourable because total revenue still looks high
  > **Test Tip:** If actual revenue is given instead of actual price, divide revenue by actual units before doing anything else.

### Sales volume variance

Sales volume variance measures the effect of selling a different number of units from the budget.

The textbook treatment often uses a **revenue basis**:

$$
\text{Sales volume variance} = (\text{Actual quantity sold} - \text{Budgeted quantity sold}) \times \text{Standard selling price}
$$

However, in AQA questions you may also see a **contribution basis**:

$$
\text{Sales volume variance} = (\text{Actual quantity sold} - \text{Budgeted quantity sold}) \times \text{Standard contribution per unit}
$$

Some wider accounting courses also use a profit basis with standard profit per unit. The key exam rule is simple: **use the basis required by the question**.

> **Key Term: sales volume variance**
> The difference caused by selling more or fewer units than budgeted.

#### Revenue basis vs contribution basis

| Basis              | Formula multiplier              | What it measures        |
| ------------------ | ------------------------------- | ----------------------- |
| Revenue basis      | standard selling price per unit | change in sales revenue |
| Contribution basis | standard contribution per unit  | change in contribution  |

If the question asks for a **sales reconciliation statement**, revenue basis is usually appropriate.

If the question is focused on profit effects in a marginal costing setting, contribution basis may be required.

#### Worked example: sales volume variance on a revenue basis

Budgeted sales = **5,000 units**  
Standard selling price = **£75**  
Actual sales = **6,000 units**

$$
\text{Sales volume variance} = (6,000 - 5,000) \times £75
$$

$$
= 1,000 \times £75
$$

$$
= £75,000
$$

The sales volume variance is **£75,000 favourable**.

Reason: 1,000 more units were sold than planned.

#### Worked example: sales volume variance on a contribution basis

Budgeted sales = **10,000 units**  
Actual sales = **10,800 units**  
Standard contribution per unit = **£6**

$$
\text{Sales volume variance} = (10,800 - 10,000) \times £6
$$

$$
= 800 \times £6
$$

$$
= £4,800
$$

The sales volume contribution variance is **£4,800 favourable**.

#### Common student errors

- using **standard selling price** when the question needs **standard contribution**
- using actual price in the volume formula
- assuming a favourable volume variance means profit definitely rose by that full amount

AQA examiners often stress that extra units sold may bring extra variable costs. So a favourable sales volume variance does not by itself prove a strong profit outcome.

### Using sales variances in a reconciliation statement

A common exam task is to reconcile **budgeted sales revenue** to **actual sales revenue**.

Structure:

$$
\text{Budgeted revenue} \pm \text{Sales volume variance} \pm \text{Sales price variance} = \text{Actual revenue}
$$

#### Worked example: full revenue reconciliation

Budget: **1,000 units at £20**  
Actual: **1,200 units at £18**

Step 1: Budgeted revenue

$$
1,000 \times £20 = £20,000
$$

Step 2: Actual revenue

$$
1,200 \times £18 = £21,600
$$

Step 3: Sales volume variance

$$
(1,200 - 1,000) \times £20 = £4,000 \text{ F}
$$

Step 4: Sales price variance

$$
(£18 - £20) \times 1,200 = -£2,400
$$

So **£2,400 adverse**

Step 5: Reconciliation

| Item                      |      £ |
| ------------------------- | -----: |
| Budgeted revenue          | 20,000 |
| Add sales volume variance |  4,000 |
| Less sales price variance |  2,400 |
| Actual revenue            | 21,600 |

This is a good check. If your reconciliation does not reach actual revenue, one of the variances is wrong.

### How to interpret sales variances in written answers

AQA does not only want the number. You also need a short explanation of what the variance means.

Good interpretation includes:

- whether the variance is **favourable** or **adverse**
- what changed: **price**, **volume**, or both
- a realistic possible cause if the question context supports it

Examples:

- “The sales price variance is **adverse** because the actual selling price was below the standard selling price.”
- “The sales volume variance is **favourable** because actual units sold exceeded budgeted units.”
- “An adverse sales price variance may indicate discounting to maintain demand in a competitive market.”

Be careful not to invent causes. If the question gives no context, use cautious wording such as “may indicate”.

### How to structure an evaluative answer

If sales variances appear in a longer discussion question, structure your answer around both **financial evidence** and **limits of that evidence**.

Use financial evidence such as:

- size of the price variance
- size of the volume variance
- net effect on revenue
- whether volume gains offset price reductions

Discuss non-financial factors such as:

- competition
- customer demand
- product quality
- marketing effectiveness
- supply problems

Then discuss limitations:

- a favourable volume variance may still leave profit weak if extra sales required discounting
- a higher sales revenue figure may hide lower margin or contribution per unit
- one month’s variance may not show the long-term pattern

A good judgement does not say “favourable is good” and stop. It explains whether the overall outcome is genuinely strong once both price and quantity are considered.
