3.6 Pricing Methods – Advantages & Disadvantages (AO1‑AO3)
| Method | Definition | When Most Appropriate | Advantages | Disadvantages |
| 1. Cost‑plus Pricing |
| Cost‑plus Pricing |
Add a standard markup to the unit cost. |
Stable cost structures; low competition. |
- Simple to calculate.
- All costs covered.
- Predictable profit margin.
|
- Ignores market demand & competition.
- May set price too high/low.
- Not responsive to consumer preferences.
|
| 2. Competition‑based Pricing |
| Competition‑based Pricing |
Set price relative to rivals (match, undercut, or price‑lead). |
Highly competitive markets (e.g., supermarkets). |
- Helps maintain market position.
- Reduces risk of price wars.
- Easy to benchmark.
|
- May ignore own cost structure.
- Can erode margins if rivals cut prices.
- Limits product differentiation.
|
| 3. Demand‑oriented (Price‑elasticity) Pricing |
| Demand‑oriented Pricing |
Set price based on how quantity demanded responds to price changes. |
When reliable elasticity data are available (e.g., airline tickets). |
- Maximises revenue if elasticity is accurate.
- Supports strategic discounts or premium pricing.
- Facilitates market‑segmentation.
|
- Requires accurate data – costly to obtain.
- Complex to calculate & monitor.
- Risk of mis‑estimation → lost sales or profit.
|
| 4. Psychological Pricing |
| Psychological Pricing |
Prices set to influence perception (e.g., £9.99 vs £10). |
Low‑involvement, fast‑moving consumer goods. |
- Creates bargain perception.
- Simple to implement.
- Effective for impulse purchases.
|
- Effect fades with savvy shoppers.
- Can appear manipulative → brand damage.
- Limited impact on high‑involvement products.
|
| 5. Penetration Pricing |
| Penetration Pricing |
Low introductory price to quickly gain market share. |
New entrants or mass‑market products. |
- Rapidly builds a customer base.
- Discourages rivals from entering.
- Creates economies of scale.
|
- Initial low profit margins.
- Risk of losing price‑sensitive customers when price rises.
- May damage perceived quality.
|
| 6. Skimming Pricing |
| Skimming Pricing |
High initial price, then reduced over the product life‑cycle. |
Innovative, luxury, or technology products with early adopters. |
- Recovers development costs quickly.
- Signals high quality/exclusivity.
- Allows price discrimination across stages.
|
- Limits market size at launch.
- Attracts competitors seeking high margins.
- Negative consumer reaction if price drops sharply.
|
| 7. Bundle Pricing |
| Bundle Pricing |
Sell a set of products/services together at a single price. |
Telecommunications, software suites, fast‑food meals. |
- Increases perceived value.
- Encourages purchase of additional items.
- Smooths demand across product lines.
|
- May reduce profit on high‑margin items.
- Complex to allocate fair price to each component.
- Customers may only want part of the bundle.
|
| 8. Dynamic (Yield) Pricing |
| Dynamic (Yield) Pricing |
Price varies with real‑time factors such as demand, time, or inventory. |
Airlines, hotels, online retailers with sophisticated data systems. |
- Optimises revenue per unit sold.
- Responds instantly to market changes.
- Can target different customer segments.
|
- Requires advanced IT & data analysis.
- Can frustrate customers if prices fluctuate widely.
- Potential regulatory scrutiny in some sectors.
|
3.7 Worked Examples (AO3)
Example 1 – Cost‑plus Pricing
Unit costs: Direct materials £12, Direct labour £8, Variable overhead £5, Fixed overhead (allocated) £3.
Unit cost = £12 + £8 + £5 + £3 = £28
Markup = 25 % → Selling price = £28 × 1.25 = £35
Example 2 – Demand‑oriented Pricing (Elasticity)
Ticket price £10 → 1,200 tickets/week; price £12 → 900 tickets/week.
E = (%ΔQ ÷ %ΔP) = [(900‑1,200)/1,200] ÷ [(12‑10)/10] = (‑0.25) ÷ 0.20 = ‑1.25
Since |E| > 1, demand is price‑elastic; raising price would reduce total revenue.
Example 3 – Competition‑based Pricing
Company A’s shampoo £8.00; rivals £7.50 and £7.80.
- Match lowest rival → £7.50
- Price‑lead → £7.40
- Premium positioning → keep £8.00 and stress quality.
Choice depends on cost, brand image, and target market.
Example 4 – Dynamic Pricing (Yield Management)
An airline monitors seat occupancy. When occupancy < 30 % 48 hours before departure, price drops 15 %; when > 80 % occupancy, price rises 20 %.
3.8 Mini‑Data Set – Choose the Best Pricing Method (AO3)
| Product | Unit Cost (£) | Competitor Price (£) | Elasticity (E) | Market Situation |
| Eco‑friendly water bottle | 3.00 | 4.20 | ‑0.8 (inelastic) | New entrant, niche eco‑market |
| Smartphone model X | 150 | 200 | ‑1.6 (elastic) | Highly competitive, rapid tech turnover |
| Monthly gym membership | 25 | 30 | ‑1.2 (elastic) | Established brand, price‑sensitive customers |
Task (AO3): Analyse each row and recommend the most suitable pricing method, justifying with cost, competition, and elasticity considerations.
3.9 Decision‑Making Flowchart (Suggested Diagram)
From cost analysis → market analysis (competition & elasticity) → product‑life‑cycle stage → legal/ethical checks → select appropriate pricing method (or combination).
Section 4 – Operations Management
4.1 Production Methods
- Job/Batch production – customised, low volume.
- Flow (mass) production – high volume, low variety.
- Lean production – minimise waste, continuous improvement.
4.2 Costs & Break‑Even Analysis (AO2)
Break‑even point (units) = Fixed Costs ÷ (Selling price per unit – Variable cost per unit).
| Fixed Costs | £50,000 |
| Selling price per unit | £25 |
| Variable cost per unit | £15 |
| Break‑even units | £50,000 ÷ (£25‑£15) = 5,000 units |
4.3 Quality Management
- ISO 9001 certification
- Six Sigma – reduce defects to 3.4 per million.
- Quality‑control checklist – specifications, inspection points, corrective action.
4.4 Location Decisions
- Factors: transport costs, labour availability, market proximity, government incentives.
- Methods: cost‑benefit analysis, break‑even for different sites.
Section 5 – Financial Information and Decisions
5.1 Sources of Finance (AO1)
| Source | Type | Typical Cost | Control |

| Current assets (stock) | 60,000 | Creditors | 30,000 |
| Cash | 20,000 | Owner’s capital | 100,000 |
| Total assets | Total liabilities & equity |
| £230,000 | £210,000 |
5.5 Key Financial Ratios (AO2)

- Current ratio = Current assets ÷ Current liabilities
- Return on capital employed (ROCE) = Profit before interest & tax ÷ (Capital employed) × 100 %
5.6 Pricing Methods – Recap (see Section 3.6)
Section 6 – External Influences on Business
6.1 Economic Cycle
- Expansion → higher consumer spending, demand‑pull inflation.
- Peak → capacity constraints, possible price rises.
- Recession → reduced demand, price‑sensitive buying.
- Recovery → gradual increase in demand.
6.2 Government Policy
- Fiscal policy – tax rates, subsidies, public spending.
- Monetary policy – interest rates, money supply.
- Regulation – health & safety, environmental standards, competition law.
6.3 Environmental & Ethical Issues
- Carbon footprints, waste reduction, sustainable sourcing.
- Corporate social responsibility (CSR) – philanthropy, ethical labour.
6.4 Globalisation & MNCs
- Opportunities: larger markets, lower production costs.
- Threats: exchange‑rate risk, cultural differences, competition from overseas.
6.5 Exchange Rates (AO1)
Appreciation of the home currency makes imports cheaper but exports more expensive; depreciation has the opposite effect.
How to Choose the Most Appropriate Pricing Method (AO4)
- Analyse the cost structure – are all costs known and stable?
- Assess the market conditions – level of competition, price sensitivity (elasticity), and consumer behaviour.
- Identify the product’s life‑cycle stage – introduction, growth, maturity, decline.
- Consider the brand positioning – premium vs. value‑oriented image.
- Check for any legal or regulatory constraints – price caps, competition law, sector‑specific rules.
- Determine the availability of data – can reliable cost, competitor, or elasticity information be obtained?
- Decide whether a single method or a combination (e.g., cost‑plus as a floor, then adjust for competition) best meets the business objectives.
Key Take‑aways
- No single pricing method fits all situations; the optimal choice depends on internal costs, external market forces, product life‑cycle, and strategic objectives.
- Understanding the advantages and disadvantages of each method enables managers to anticipate risks and align pricing with overall business goals.
- Combining methods (e.g., cost‑plus baseline plus competition‑based adjustments) often yields a balanced, flexible approach.
- Always verify that chosen pricing strategies comply with legal controls and consider the wider external environment (economic, social, environmental).
