Break even analysis is a key financial planning tool that helps businesses understand at what level of production or sales they will neither make a profit nor incur a loss. This point is called the break even point.
The level of output at which total revenue equals total costs, resulting in zero profit and zero loss.
Understanding the break even point is essential for business planning. It tells a business the minimum level of sales needed to cover all costs. Knowing this figure helps managers set realistic sales targets and make informed decisions about production levels and pricing.
Before calculating break even, it is important to understand the concept of contribution. Contribution is the amount of money each unit sold puts towards paying off fixed costs. Once enough units have been sold so that total contribution covers all fixed costs, the business reaches break even. Every unit sold after that point generates profit.
The selling price of one unit minus the variable cost of producing that unit. It represents how much each unit sold "contributes" towards covering fixed costs and eventually generating profit.
This tells you how much money from each sale is left over after covering the direct costs of making that product.
A bakery sells cakes for 12 pounds each. The ingredients and packaging cost 4 pounds per cake. Contribution per Unit = 12 − 4 = 8 pounds. So every cake sold contributes 8 pounds towards paying fixed costs like rent and salaries.
Total contribution shows the combined amount all units sold have contributed towards fixed costs. If total contribution exceeds fixed costs, the business is making a profit. If it falls short, the business is making a loss.
The bakery sells 500 cakes in a month. Total Contribution = 8 × 500 = 4,000 pounds. If the bakery's fixed costs are 3,000 pounds per month, then Profit = 4,000 − 3,000 = 1,000 pounds.
The word "contribution" is very specific in business. It does not mean profit. Contribution is what each unit puts towards fixed costs first. Only after all fixed costs are covered does contribution become profit. Make sure you use the term correctly in your answers.
Contribution is directly linked to break even because the break even formula uses contribution per unit as its denominator. The higher the contribution per unit, the fewer units a business needs to sell to cover its fixed costs.
Since Contribution per Unit = Selling Price − Variable Cost per Unit, the formula can also be written as: Fixed Costs / (Selling Price − Variable Cost per Unit).
Fixed costs are 50,000 pounds, selling price is 25 pounds per unit, variable cost is 10 pounds per unit. Contribution per Unit = 25 − 10 = 15 pounds. Break Even Output = 50,000 / 15 = 3,333 units (rounded). The business must sell at least 3,334 units to start making a profit.
The difference between the expected sales level and the break even point, showing how much sales can fall before the business starts making a loss.
This can also be expressed as a percentage: (Margin of Safety / Expected Output) x 100.
If expected output is 5,000 units and break even output is 3,333 units, then Margin of Safety = 5,000 - 3,333 = 1,667 units. As a percentage: (1,667 / 5,000) x 100 = 33.4%.
A break even chart visually represents the relationship between output and profit. It shows total revenue and total costs as lines, with their intersection point indicating the break even point. The area above the total revenue line shows profit, while the area below shows loss.
A McDonald's franchise owner must know their break even point to determine how many meals they need to sell daily to cover costs. With fixed costs like rent, staff salaries, and utilities, and variable costs for food and packaging, understanding break even helps franchisees set realistic profit targets and decide on pricing strategies.
When a question asks about margin of safety, remember it shows the cushion a business has before it starts making losses. A larger margin of safety means lower business risk.

TechStart Ltd is a software startup founded in 2022 by two university graduates, James and Priya. The company develops mobile apps for small businesses, helping them manage bookings, payments, and customer communication. The business has grown from 3 to 15 employees in just two years. Revenue has increased from £50,000 in the first year to £320,000, representing 540% growth. However, cash flow remains tight because developers must be paid monthly while clients often pay 60 days after project completion. The founders are now considering whether to seek £500,000 venture capital investment to speed up growth, or continue growing organically through retained profits. Staff turnover has recently increased, with three developers leaving in the past six months for higher-paying jobs at larger tech firms.
There are many factors that TechStart should consider when deciding its growth strategy. One important factor is finance. Finance is the money that a business uses to fund its activities. TechStart needs to decide whether to get venture capital or use retained profits. Venture capital means getting money from investors who want a return on their investment. This would give TechStart £500,000 to spend on growth. Retained profits means using the money the business has already made. This is safer because you do not owe anyone anything.
Another factor is human resources. Human resources is the management of people within a business. When a business grows, it needs more employees and this can be difficult to manage. TechStart has gone from 3 to 15 employees which is a lot of growth.
However, there are risks with growing too fast. If a business grows too quickly it can run into cash flow problems. This is called overtrading.
In conclusion, I think the most important factor is finance because without money a business cannot do anything.
≈ 6/20 marks (Level 2). This answer reads like a textbook. The application is shallow and each point is stated but never built into a chain of reasoning.
PBLI 1 + Balance: [P] The source and speed of funding is a key factor, as venture capital provides quick access to large amounts of money, and in a competitive market speed of growth can determine whether a business survives or fails. [B] TechStart's founders are considering £500,000 of VC funding, which would be a huge amount for a business that has only grown from £50,000 to £320,000 revenue in two years. [L] This leads to the ability to hire specialist developers, invest in marketing, and take on larger client projects at the same time rather than one after another, [I] meaning the VC funding question is really a question about speed, and the cost of slow organic growth is not just missed revenue but the risk of being overtaken entirely in a fast-moving market.
However, [P] VC investors usually want board seats, regular reports, and a plan for how they will get their money back, and rapid expansion also carries the risk of overtrading. [B] As two university graduates who built TechStart from scratch, James and Priya may not have the experience to deal with professional investors. Their cash flow is already "tight" despite strong revenue growth, and clients take 60 days to pay. [L] This could lead to business decisions being driven by what investors want rather than what is best for the product, while aggressive growth could make the cash flow gap worse.
PBLI 2 + Balance: [P] Managing people becomes much harder during rapid growth, and the ability to recruit, train and keep skilled staff is essential, particularly in an industry where the product depends entirely on the quality of the workforce. [B] TechStart has expanded from 3 to 15 employees in just two years, and three developers have already left in the past six months for higher-paying jobs at larger tech firms. [L] This leads to pressure on the founders' time and management capacity, and each developer who leaves takes knowledge of TechStart's code and client relationships with them, [I] which risks lower productivity, lost clients, and a damaged reputation if projects are delayed or quality drops.
However, [P] not investing in competitive salaries could be just as damaging, because in a knowledge-based industry losing key staff can set a business back more than any financial loss. [B] The tech industry is described as "highly competitive and fast-moving", meaning TechStart's remaining developers are likely being approached by larger, better-paying employers regularly. [L] This means without growth capital to fund competitive pay and training, the turnover problem will only get worse.
Conclusion (MOPS: Market): Overall, the most important factor is the competitive nature of TechStart's market, because this is what makes every other decision so urgent. In a fast-moving technology sector where larger competitors could copy their products within months, the window to build a strong market position is narrow. In the short term, accepting VC investment will create pressures around control and culture. In the long term, however, growing too slowly could threaten the survival of the business entirely.
