What Is Break-Even Point?
Break-even point is the level of sales at which your business covers all its costs and begins to make a profit. Every business owner should know this number.
Key Takeaways
- Break-even is the revenue level at which total costs equal total revenue — profit is zero.
- It is calculated by dividing fixed costs by the contribution margin ratio.
- Knowing your break-even helps you set realistic sales targets and price confidently.
- Every business decision that changes your fixed costs or pricing shifts the break-even.
What break-even means
Break-even point is the level of sales at which your business generates exactly enough revenue to cover all its costs — fixed and variable — leaving neither profit nor loss. Above the break-even, every additional unit sold generates profit. Below it, the business is loss-making. For a product business, break-even is often expressed in units sold. For a service business or multi-product company, it is typically expressed as a revenue figure. Knowing your break-even is essential for setting minimum sales targets, evaluating the viability of a new product or venture, and understanding how much of a revenue cushion you have in a downturn.
How to calculate it
The formulas are: Break-Even Units = Fixed Costs ÷ Contribution Margin per Unit, or Break-Even Revenue = Fixed Costs ÷ Contribution Margin Ratio. Contribution margin per unit is selling price minus variable cost per unit. Contribution margin ratio is contribution margin ÷ selling price, expressed as a percentage. Example: if fixed costs are £60,000 per year, selling price is £100, and variable cost per unit is £40, contribution margin per unit is £60 and the break-even is 1,000 units (£60,000 ÷ £60). That means you need to sell 1,000 units per year before making any profit — unit 1,001 onwards is profit.
How pricing and costs shift the break-even
Break-even analysis is most powerful when used to test decisions. Increasing your price (if demand supports it) lowers your break-even — fewer units needed to cover fixed costs. Reducing variable costs (better supplier terms, more efficient production) has the same effect. But adding fixed costs — a new member of staff, a bigger office, additional software — raises your break-even. Before committing to any material fixed cost increase, recalculate your break-even and confirm your current sales trajectory is comfortably above it. Many businesses make fixed cost commitments that raise break-even above current revenue, creating immediate pressure on performance.
Break-even and margin of safety
The margin of safety is the gap between your current revenue and your break-even: Margin of Safety = (Current Revenue − Break-Even Revenue) ÷ Current Revenue × 100%. A margin of safety of 30% means revenue could fall by 30% before the business becomes loss-making. A margin of 5% means you are operating very close to break-even and are highly vulnerable to any sales disruption. Use the margin of safety to calibrate how much risk your business can absorb, and to decide how aggressively to pursue growth versus how conservatively to manage costs. For businesses in volatile markets, maintaining a margin of safety of at least 20% is a reasonable target.
