The break-even point is the level of sales at which total revenue equals total cost. Below it, the business loses money. Above it, each additional sale contributes toward profit, assuming prices and costs behave as expected.
The calculation starts by separating costs into two broad groups.
Fixed costs do not normally change directly with each unit sold over the period being examined. Rent, core administrative salaries and some licences are common examples. Variable costs rise as output or sales increase, such as direct materials, transaction fees or packaging.
The difference between the selling price of one unit and its variable cost is the contribution per unit. Dividing total fixed costs by that contribution gives the break-even volume.
For example, if a product sells for G$10,000 and has G$6,000 in variable cost, it contributes G$4,000 toward fixed costs and profit. If monthly fixed costs are G$800,000, the simplified break-even point is 200 units.
This is a management estimate, not a tax calculation or audited result. Real businesses may sell several products, offer discounts, face step-changes in staffing or capacity, and experience cost movements. A useful model should therefore state its assumptions and test more than one scenario.
World Bank SME financial-management material places financial analysis and investment assessment among the capabilities that support stronger planning. Break-even analysis helps answer practical questions:
- Can the expected market support the required sales volume?
- What happens if a supplier increases its price?
- How much room is available for a discount?
- When would an additional employee or piece of equipment become affordable?
- How far can sales fall before the business starts losing money?
The margin of safety is the difference between expected sales and break-even sales. A narrow margin means that a small disruption could remove the projected profit.
Break-even analysis does not measure cash timing, financing costs or every risk. It works best alongside a cash-flow forecast and sensitivity analysis. Its value lies in making the economics visible before a business commits money.
