Sales, revenue and costs

Fixed costs are costs that do not change with the level of output (1) — such as rent, salaries or insurance — and must be paid even if the business produces nothing (1).

Revenue = £10 × 3,000 = £30,000. Total costs = £10,000 + (£4 × 3,000) = £10,000 + £12,000 = £22,000 (Knowledge 1, formulae; Application 2, substitution). Profit = total revenue − total costs = £30,000 − £22,000 = £8,000 (Analysis 1).

Way 1 — reduce variable costs. Profit = revenue − costs, so lowering costs raises profit (Knowledge). SnackCo could negotiate bulk-buying discounts on raw ingredients and raise its factory capacity utilisation to drive down its unit production cost (Application). This widens the contribution margin between revenue and total costs, raising profit on every snack pack it produces and sells (Analysis).

Way 2 — increase revenue. Revenue can rise via price or volume (Knowledge). SnackCo could raise its price, exploiting the price-inelastic demand for its brand, or lift sales volume through promotion and wider distribution (Application). Higher revenue widens the gap over its fixed production overheads, increasing profit as each additional unit spreads those overheads further (Analysis).

Cutting costs would raise PremiumBite's contribution per unit and is quick to implement. However, for a premium brand, the obvious cost cuts — cheaper ingredients or lower-grade packaging — risk lowering quality, which could damage the brand's reputation and the premium price and loyalty it depends on. Cost-cutting that customers detect on the shelf could reduce revenue by more than it trims from unit production cost.

Raising revenue may fit PremiumBite better. As a premium brand, its customers are likely loyal and less price-sensitive, so PremiumBite could raise its price or extend its product range to lift revenue without harming its image — turning its brand strength into higher profit.

Which is more appropriate therefore depends on how PremiumBite can achieve each without harming its brand. Because cost-cutting on a premium product risks the quality and image that justify its prices, raising revenue is generally more appropriate for PremiumBite. That said, if it can cut costs invisibly — through greater production-line efficiency or better bulk-buying terms with suppliers that don't affect the finished product — then cost reduction could raise profit safely too. On balance, PremiumBite should prioritise revenue-raising that leverages its brand, using only quality-neutral efficiencies and supplier savings, to protect the premium positioning its profit ultimately rests on.

In a competitive, price-sensitive market, how CostCo improves profit matters, and cost-cutting is one route — but whether it is best depends on the trade-offs and alternatives.

The case for cutting costs. Because CostCo's market is price-sensitive, it cannot easily raise prices without losing sales (elastic demand), so cutting costs — negotiating bulk-buying discounts with suppliers, raising factory capacity utilisation, and trimming warehousing and overhead — directly widens its margin and raises profit without touching price. Lower unit production costs could even let CostCo cut prices to win share while protecting profit. For a price-competitive producer, cost efficiency is often the most realistic lever.

The case against / alternatives. However, cost-cutting has limits and risks. Cheaper components or under-investment in plant can lower quality, losing customers even in a price-sensitive market, and staff cuts can harm productivity and morale. There is also a floor — unit costs can only be squeezed so far. Alternatives include raising sales volume (through better marketing or new products), improving efficiency/productivity (cutting unit costs through economies of scale without cutting quality), or differentiating to escape pure price competition.

Judgement. On balance, cutting costs is likely among the best routes for CostCo given its price-sensitive market, because raising prices is hard, so efficiency-based cost reduction that lowers unit costs without harming quality is especially valuable. But it is not the sole answer: CostCo should combine quality-neutral cost-cutting with efforts to raise volume (spreading fixed factory overheads over more units) and, if possible, differentiate to reduce its exposure to price competition. So cost-cutting is best when it comes from efficiency rather than cutting corners, and works best alongside revenue-raising — the right emphasis depends on how much CostCo can cut unit costs without damaging quality.

Profit is revenue minus costs, so TradeCo can raise it by increasing revenue or reducing costs — but the most effective route depends on its market, its cost structure and the risks each carries.

Increasing revenue. TradeCo could raise revenue by raising price (only effective if demand is inelastic — a strong brand or few substitutes), increasing sales volume (lifting footfall conversion and average transaction value through marketing, new lines or new outlets), or adding value to justify higher prices. Revenue growth is powerful because it can lift profit substantially and supports the business's expansion. However, it has risks and costs: a price rise loses sales if demand is elastic; boosting volume usually needs spending on marketing and promotion (which may not pay off); and opening new outlets carries risk. Revenue-raising also depends heavily on market conditions TradeCo cannot fully control.

Reducing costs. TradeCo could cut variable costs (bulk-buying discounts on stock, cheaper supply terms) or fixed costs (lower rent and store overheads), or raise efficiency/productivity — improving inventory turnover so less capital is tied up in unsold stock — to cut unit costs. Cost reduction directly widens the margin and is often within TradeCo's control. But cutting costs by stocking lower-quality lines or under-investing in the shopfloor can damage the product range, brand and staff motivation, ultimately reducing revenue by more than it saves — and there is a limit to how far costs can fall.

Evaluation. The most effective way depends on several factors. It depends on TradeCo's market: in a price-sensitive, competitive market, raising price is hard, so efficiency-based cost reduction may be most effective; in a market where TradeCo can differentiate, raising revenue through added value may yield more. It depends on PED: inelastic demand favours a price rise; elastic demand favours volume or cost routes. It depends on which lever TradeCo controls and its cost structure — a high-fixed-cost retailer (rent, staff) benefits greatly from higher volume (spreading fixed costs across more transactions), a high-variable-cost one from cheaper stock. And it depends on the time horizon and risk — some routes pay off quickly, others need investment.

Conclusion. On balance, there is no single most effective way for TradeCo — the best approach is usually to combine quality-neutral cost efficiency with targeted revenue growth, matched to its market. Where demand is inelastic and TradeCo can differentiate, raising revenue (price/value/volume) is likely most effective; where the market is price-sensitive, efficiency-driven cost reduction that protects quality is likely most effective. The decisive factor is doing whichever route without damaging the other side of the equation — cutting costs without harming the range and service quality that drive footfall and revenue, or raising revenue without inflating costs. So TradeCo should pursue both levers carefully and in balance, prioritising the one its market and cost structure most reward, rather than relying on either alone.
