What is the Break-Even Point?
The break-even point (BEP) is the sales volume at which the company starts to generate profit. Below that point, every unit sold produces an operating loss; above it, every additional unit contributes to profit.
It's one of the most important metrics for any SME — especially in start-up or expansion phases, when it's crucial to know the minimum revenue needed to make operations sustainable.
The difference between selling price and variable cost (SP − VC) is called the unit contribution margin — it's the amount each unit sold "contributes" to covering fixed costs. Only when all fixed costs are covered does the business start to make a profit.
The difference between fixed and variable costs
This distinction is fundamental for calculating break-even correctly. A common mistake is to include variable costs among the fixed ones — which distorts the result and can lead to wrong pricing decisions.
| Type | Typical examples | Varies with sales? |
|---|---|---|
| Fixed Costs | Rent, base salaries, insurance, software licences, accounting, depreciation | No |
| Variable Costs | Raw materials, packaging, sales commissions, per-order shipping, processing fees | Yes — proportional to volume |
| Semi-variable Costs | Electricity, telecoms, flexible labour | Partially |
Practical tip: for semi-variable costs, estimate the fixed component (guaranteed minimum cost) and include it in fixed costs. The variable component can be allocated to the variable cost per unit.
Contribution margin explained
The contribution margin (CM%) is one of the most powerful indicators for pricing and scale decisions. It tells you what percentage of every pound of revenue is left to cover fixed costs and generate profit.
Example: if your selling price is £100 and the variable cost is £40, the unit CM is £60 and the CM% is 60%. That means out of every £100 invoiced, £60 stays with the company — and only £40 "goes out" to fund production.
A high CM% means each additional sale has a proportionally bigger impact on profit. Businesses with CM% above 60% (software, services, premium products) scale far more efficiently than businesses with CM% below 30% (volume retail, distribution).
3 ways to lower your break-even
-
1Reduce fixed costs
Every pound cut from fixed costs lowers break-even directly. Review annual contracts, negotiate rent during quiet periods, consider pay-per-use models instead of fixed licences, and outsource anything non-core into variable structures.
-
2Raise prices through repositioning
A 10% price increase with the same cost structure can reduce break-even by 15-25%. Premium positioning justifies higher prices — and the customers who stay are more profitable and loyal. Analyse where you sit relative to competitors.
-
3Improve margin on existing sales
Review your variable cost base: renegotiate with suppliers based on volume, drop low-margin SKUs that consume management resources, and focus commercial effort on the products or services with the highest CM%. Healthy cash flow helps you secure better purchasing terms — factoring can free up liquidity to pay early and capture discounts.
