Sales may be coming in, customers may be buying, and your revenue may look healthy, but that does not always mean your business is making money.
If this sounds familiar, it could be a sign of what many businesses fall into: the growth trap. They see a surge in revenue and assume the growth strategy is working. But if fixed costs are rising faster than margins, or if your price point is too low, increased sales can still lead to a cash-flow crisis.
This is why the break-even point formula is such a useful tool. It helps you test whether your pricing strategy is strong enough to support growth, not just whether your business can generate a higher volume of sales.
Your break-even point shows how much you need to sell before your business starts making a profit. It is the point where your revenue matches your total costs. Once you move beyond that point, each additional sale starts contributing to profit.
For South African small and medium-sized businesses, a break-even analysis is a practical way to set prices, manage costs and make better business decisions.

What Is the Break-Even Point?
The break-even point is the point where your total revenue equals your total costs. At this even point, your business is not making a profit, but it is not making a loss either.
In simple terms, your business has reached break-even when sales revenue has covered all your costs.
A break-even analysis determines the minimum sales required to cover your fixed costs and variable costs. Once your sales move past the break-even point, the contribution margin from each additional sale starts contributing to net profit.
This makes the break-even point a useful pricing test. It shows whether your current sales price can support your cost structure, and whether your business can scale sustainably.
Knowing your business’s break-even point is especially useful when you plan to launch a new product, or are reviewing your selling price, preparing a business plan, setting sales targets, applying for business funding or planning production volume.
It is also useful for existing businesses because it shows whether current sales are safely above the break-even point, or whether a drop in sales volume could put the business under pressure.
The Components of the Break-Even Point Calculation
Before you calculate your business’s break-even point, you need to understand three key numbers: your total fixed costs, your total variable costs and your contribution margin.
Understanding fixed costs
Fixed costs are the costs that stay the same regardless of how many units you sell in a given period. These are also known as overheads.
Common fixed costs include:
– Rent,
– Payroll,
– Insurance,
– Internet and phone contracts
– Software subscriptions
– Loan repayments
– Accounting fees
– Basic utilities
For example, if a retail store pays R30,000 in rent every month, that amount stays the same whether the store sells 500 items or 5,000 items. The amount forms part of total fixed costs.
The higher your total fixed costs, the more sales you need to make to break even. This is why it is important to run a break-even analysis before committing to larger expenses in your business, like signing a bigger lease, hiring more staff or expanding into a new location.
Identifying variable costs
Variable costs change depending on how many units you produce or sell. These are the direct costs linked to each sale.
Common variable costs include:
– Raw materials,
– Stock purchases,
– Packaging,
– Delivery fees,
– Payment processing fees,
– Direct labour,
– Sales commissions and
– Production supplies.
For example, a bakery’s variable costs may include flour, sugar, eggs, packaging and delivery. A retailer’s variable costs may include the cost of buying stock from suppliers, plus packaging and courier fees.
To calculate the break-even point accurately, you need to know your variable cost per unit. This is the cost of producing or selling one unit.
If you sell a product for R200 and it costs R90 in stock, packaging and delivery to sell it, your variable cost per unit is R90.
Contribution margin
Contribution margin is the money left over from each sale after variable costs have been deducted.
The basic formula is:
Contribution margin = selling price – variable cost per unit
For example, if your selling price is R200 and your variable cost per unit is R90, your contribution margin is:
R200 – R90 = R110
This means each unit sold contributes R110 toward covering fixed costs. Once your fixed costs are fully covered, every cent of the contribution margin becomes profit.
You can also calculate the contribution margin ratio. This is useful when you want to calculate break-even sales in rand value instead of units.
Contribution margin ratio = contribution margin / selling price
Using the same example:
R110 / R200 = 55%
This means 55% of each sales rand is available to cover fixed costs and contribute to profit.
The Break-Even Point Formula
There are a few ways to determine a break-even point, and the best break-even point formula depends on the type of business and what you need to calculate.
The unit-based formula:
If your main question is, “How many must I sell?”
The unit-based formula is:
Break-even point = total fixed costs / contribution margin per unit
This formula is useful when you sell a specific product or service and want to know how many units must be sold to cover all your costs.
Let’s say you run a coffee shop. Your monthly total fixed costs are R55,000. Your selling price per coffee is R35. Your variable cost per unit is R15.
First, calculate contribution margin:
R35 – R15 = R20
Now calculate the break-even point:
R55,000 / R20 = 2,750 coffees
This means the coffee shop must sell 2,750 units of coffee per month to break even.
If the shop trades for 25 days per month:
2,750 / 25 = 110 units of coffee per day
So, the business needs to sell 110 coffees per day before it starts making a net profit from coffee sales.
The sales value formula:
If your main question is, “How much revenue do I need?”
The sales value formula is:
Break-even sales = total fixed costs / contribution margin ratio
This formula is useful for retail businesses with many different products. Instead of showing how many units must be sold, it shows the total rand value that needs to pass through the till to break even.
Let’s say a clothing store has total fixed costs of R120,000 and an average contribution margin ratio of 40% (0.40).
R120,000 / 0.40 = R300,000
This means the store needs R300,000 in monthly sales revenue to break even.
This is useful for retailers, wholesalers, restaurants and online stores that sell multiple products with different prices and margins.
Practical Examples for South African Small Businesses
Case study 1: The boutique manufacturer
A local clothing brand wants to increase production. The owner is considering renting a bigger factory space and investing in machinery.
Before committing to the new fixed costs, the owner uses the break-even point formula to test the pricing.
The business has:
- Total fixed costs of R150,000;
- A selling price of R750 per item; and
- Variable costs of R450 per item.
Contribution margin:
R750 – R450 = R300
Break even point:
R150,000 / R300 = 500 units
The business must sell 500 units per month before making a profit. If current demand is only 300 units, the owner knows the expansion may create cash-flow pressure unless they raise prices, reduce costs or secure more orders first.
Case study 2: The service provider
A small digital agency wants to hire another designer. The owner needs to know whether the business can cover the additional salary and office overheads.
The agency has:
- Total fixed costs of R90,000;
- An hourly billing rate of R900; and
- Variable costs of R150 per billable hour.
Contribution margin:
R900 – R150 = R750
Break-even point:
R90,000 / R750 = 120 billable hours
The agency needs 120 billable hours per month to break even. If the team can consistently bill more than this, hiring may make sense. If not, the owner may need to review pricing or delay the hire.
For more detailed planning, build your break-even analysis alongside a cash flow forecast template.
Strategic Application: Using Your Break-Even Point To Guide Pricing
The break-even point (BEP) formula is not just a calculation, it’s a useful pricing test.
If your BEP requires an impossible volume of sales, your price may be too low or your costs may be too high.
For example, if a business needs to sell 10,000 units a month just to break even, but current demand is closer to 3,000 units, the problem is not only sales volume. The business may need to review its sales price, variable cost per unit, supplier terms or fixed expenses.
This is why doubling sales does not always solve cash-flow pressure. If margins are too thin, higher sales can mean higher variable costs, more stock pressure and rising overheads without enough profit to support the growth.
Use your break-even analysis before committing to new fixed costs like a bigger office, more staff or higher stock levels. It gives you a clearer view of whether growth is financially sustainable.
For a deeper view of profitability, use your break-even analysis alongside a profit and loss statement.
Using the Break-Even Analysis To Scale
Your break-even point can also help you understand when it may be time to scale.
If your business is consistently selling above break even, and your cash flow is healthy, this can be a signal that you may be ready to increase production, hire another employee, buy more inventory or move into a larger space.
But this decision should be taken with great care and consideration. Growth often increases fixed costs before the extra revenue arrives. This is where cash flow planning becomes important.
You can use a cash flow projection to test whether your business has enough working capital to support higher sales volumes.
If your numbers show a clear and sustainable path to profitability, the right funding can help you move faster. Lula’s Cash Flow Facility can act as a reserve that gives your business access to capital when you need it, without building unnecessary pressure into your day-to-day running costs.
