📖 The Financial Foundations
Every business needs to understand three core financial concepts: how much money comes in (revenue), how much goes out (costs), and what's left over (profit or loss).
Revenue = Selling Price × Quantity Sold
Profit = Total Revenue − Total Costs
Loss = Total Costs − Total Revenue (when costs exceed revenue)
💰 Revenue (Turnover)
Revenue is all the money flowing INTO the business from sales. It is also called turnover or sales revenue.
Revenue (also called turnover or sales revenue) is the total amount of money received by a business from selling its goods or services, before any costs are deducted.
Revenue = Selling Price × Quantity Sold
🧮 Revenue Calculations — Worked Examples
Example 1: Bakery
£2.50 × 80 = £200
Example 2: Phone Shop
£450 × 120 = £54,000
📈 How to Increase Revenue
- Increase selling price — more revenue per unit sold (risk: may reduce demand)
- Sell more units — through better marketing, new products, new markets
- Enter new markets — reach new customer groups
- Launch new products — additional revenue streams
⚠️ Important: High revenue does NOT mean profit. A business can have huge revenue but still make a loss if its costs are even higher.
📊 Costs
Costs are all the money flowing OUT of the business. Understanding the difference between fixed and variable costs is essential for calculations and exam questions.
🔒 Fixed Costs
Costs that stay the same regardless of how much the business produces or sells. They must be paid even if output is zero.
- Rent / mortgage payments
- Manager and staff salaries
- Insurance premiums
- Loan repayments
- Marketing / advertising contracts
Example: A gym pays £3,000/month rent whether 10 or 1,000 members visit.
📈 Variable Costs
Costs that change with output — they rise as production increases and fall as it decreases.
- Raw materials and ingredients
- Packaging
- Hourly wages / piece-rate pay
- Delivery and postage costs
- Electricity used in production
Example: A bakery spends more on flour and eggs the more loaves it bakes.
Total Costs = Fixed Costs + Variable Costs
This is the total amount of money flowing out of the business in a given period.
🧮 Worked Example: Total Costs
A small clothing manufacturer per month:
📈 Profit, Loss & Break Even
Profit is what remains after all costs are paid. It's the ultimate measure of a business's financial health.
📈 Profit
Profit = Total Revenue − Total Costs
When revenue is greater than total costs, the business makes a profit. This money can be:
- Kept by the owner as personal income
- Reinvested to grow the business
- Paid to shareholders as dividends
- Saved as a financial cushion
📉 Loss
Loss = Total Costs − Total Revenue
When costs exceed revenue, the business makes a loss. This is:
- Common (and acceptable) for new businesses
- Funded by savings, loans or investment
- Dangerous if it continues long-term
- A signal to cut costs or increase revenue
⚖️ Break Even
Break even is the point at which total revenue exactly equals total costs — the business makes neither profit nor loss. This is an important milestone, especially for new businesses.
Break-Even Output = Fixed Costs ÷ (Selling Price − Variable Cost per Unit)
The bottom part of this formula (Selling Price − Variable Cost per Unit) is called the contribution per unit.
🧮 Break-Even Worked Example
A candle business:
The business must sell 100 candles per month to break even. Every candle sold beyond 100 generates £6 of profit.

Sunrise Café — Monthly Figures
❌ Loss Example
New Florist — Month 1
A loss in month 1 is common — it takes time to build a customer base. The owner must fund this shortfall from savings or a loan.
✅ Improve Profit — Options
- Increase revenue: raise prices, sell more, add new products
- Reduce fixed costs: move to cheaper premises, renegotiate contracts
- Reduce variable costs: find cheaper suppliers, reduce waste
- Both together — most effective approach
🏢 Revenue, Costs & Profit in Real Business
Understanding how real businesses manage their finances brings these concepts to life.
☕ Case Study: Starbucks — Revenue vs Profit
- Starbucks generates approximately $35 billion in annual revenue globally
- Yet its net profit margin is only around 10–12% — meaning most of the revenue is consumed by costs
- Major costs: staff wages (largest cost), rent on thousands of locations worldwide, ingredients, marketing
- Key lesson: high revenue ≠ high profit — cost management is just as important as sales
- Starbucks charges premium prices precisely to maintain profit margins despite high fixed costs
💡 Even a $35bn revenue business can have thin profit margins if costs are not controlled.
🚀 Case Study: Amazon — Years of Losses Then Profit
- Amazon made a loss for its first 7 years of trading (1994–2001)
- Jeff Bezos deliberately kept prices low and reinvested all revenue into growth — prioritising market share over profit
- Fixed costs were enormous: warehouses, technology infrastructure, staff
- Once scale was achieved, revenue grew faster than costs — profit followed
- In 2023, Amazon made over $30 billion net profit
✅ Sometimes making a loss short-term is a deliberate strategy — but it requires funding (investment) to survive.

Financial calculations are guaranteed in Paper 1. Here's how to score every mark.
⚠️ Common Mistakes
- Forgetting the revenue formula — it's Price × Quantity, not just "money received"
- Confusing profit and revenue — high revenue does NOT mean profit
- Not showing working — even a wrong answer gets method marks if working is shown
- Mixing up fixed and variable costs — fixed stay the same; variable change with output
- Forgetting to include ALL costs when calculating total costs
In calculation questions, 2 marks are awarded. Writing the correct answer gets you both marks. It is good practice to write the full workings e.g: "Revenue = £8.50 × 1,200 = £10,200" — that way, if you accidentally round the answer wrong on the final line, the examiner can still find you a mark within your workings.
Always include the £ sign in financial answers and check whether the question asks for daily, monthly or annual figures. Many students lose marks by giving monthly profit when the question asks for annual.
Ask yourself: "Would this cost change if the business produced nothing?" If yes → variable. If no → fixed. Rent stays the same whether you make 0 or 10,000 products → fixed. Materials go to zero if you make nothing → variable.
📝 Model Calculation Answer
Question: "Calculate the monthly profit for a business with the following data: sells 500 units at £12 each; fixed costs £2,400; variable costs £5 per unit." (4 marks)
Revenue = £12 × 500 = £6,000
Variable Costs = £5 × 500 = £2,500
Total Costs = £2,400 + £2,500 = £4,900
Profit = £6,000 − £4,900 = £1,100
