A small food producer in Georgetown has spent months developing a new range of sauces. Retailers like the samples, and several want to place regular orders. The founder is ready to rent more production space and hire staff, but one question should come before the expansion: how many cases must the business sell each month before the new operation pays for itself?
That is a break-even question. It is not the same as asking whether customers are interested, or whether an individual sale brings in more than the ingredients cost. A business must cover the expenses that continue even when sales are slow. Break-even analysis gives the founder a clear sales threshold against which to test the opportunity.
The point where revenue catches up with cost
A business breaks even when revenue equals the costs included in its model for a defined period. At that point it has neither an operating profit nor an operating loss on those assumptions. Beyond it, additional sales may contribute to profit; below it, the operation is not covering the costs modelled.
For a single product, the calculation begins with the contribution from each sale. Contribution is the selling price minus costs that vary with the number of units sold. If a case sells for G$10,000 and ingredients, packaging and other variable costs amount to G$6,000, each case contributes G$4,000 towards fixed costs. If the operation’s relevant fixed costs are G$800,000 per month, it must sell 200 cases to cover them: G$800,000 divided by G$4,000.
At 200 cases, sales would be G$2 million. Variable costs would be G$1.2 million, leaving G$800,000 to meet fixed costs. The illustrative operating result is zero. At 250 cases, contribution rises to G$1 million and the result becomes a G$200,000 operating profit. At 180 cases, contribution is only G$720,000 and the business falls G$80,000 short of its fixed costs.
The G$4,000 contribution is 40% of the G$10,000 selling price. On the same assumptions, G$800,000 of fixed costs divided by that 40% contribution margin gives a G$2 million monthly break-even sales value, matching 200 cases. This sales-value view is useful when an investor has a revenue forecast but cannot immediately see the unit threshold behind it. It should not be used as if every product or sales channel earns the same 40%: a change in mix changes the amount left from each dollar of sales.
The U.S. Small Business Administration’s break-even guidance sets out the same core relationship: fixed costs divided by selling price less variable cost per unit. The arithmetic is simple. The harder work is choosing figures that reflect how the business will actually operate.
What belongs in the calculation?
Fixed costs are those that do not change directly with each additional case sold within the period and capacity being modelled. Rent, certain salaries, insurance and a baseline of utilities may fall in this group. Variable costs rise with output: ingredients, packaging, some freight, commissions and other per-case expenses. Some costs have both fixed and variable elements, so the founder may need to separate them rather than place the whole bill in one category.
The time period must also be consistent. A monthly sales target should be compared with monthly fixed costs. A yearly insurance premium may need an appropriate monthly allocation for planning. A one-off investment in equipment should not simply be treated as if the entire purchase price recurs every month. The model should say whether it is measuring an operating result before financing costs and tax or a broader profit measure, and include costs accordingly.
The founder must also ask whether the proposed price is realistic. A contribution of G$4,000 per case assumes the business actually receives G$10,000 and keeps variable costs at G$6,000. If retailers demand a G$1,000 discount while variable costs stay the same, contribution falls to G$3,000. The business would then need to sell at least 267 cases, rounding up from 266.7, merely to cover G$800,000 of fixed costs. A modest price change can therefore move the threshold substantially.
Those calculations assume the same fixed costs and sufficient production capacity across the volumes compared. A new shift, refrigerated vehicle or larger premises might become necessary above a particular output. Such a step cost raises the threshold just when sales appear to be improving. Similarly, a supplier’s price may rise with imported inputs, or a retailer may take a promotional discount. The SBA guidance notes that mixed costs should be separated where possible. A credible model identifies the range over which its costs and price assumptions hold, rather than extending one neat formula indefinitely.
Break-even is a test, not a forecast
The calculation tells the producer what must happen; it does not prove that it will happen. A forecast that assumes 250 cases each month should be tested against retailer commitments, repeat-purchase behaviour, seasonality, production capacity and distribution. If the equipment can produce only 220 cases, a break-even point of 267 is not an achievable target without changing the operation.
The timing of reaching the threshold matters too. Break-even for one month means that month’s modelled revenue covers that month’s modelled costs. It does not automatically recover losses accumulated during the first months of production or repay the founder’s original equipment investment. If sales ramp slowly, the business needs enough funding to absorb the early deficit before the first break-even month. An investor therefore needs both a steady-state threshold and a credible path to reaching it; the first profitable month is not the same thing as an investment payback date.
The distance between expected sales and break-even sales is often called the margin of safety. At a forecast of 250 cases and a break-even point of 200, the business has a buffer of 50 cases. That buffer may look comfortable until the founder considers a delay in obtaining stock, a retailer returning unsold product or a rise in ingredient costs. Testing a slower-sales case is more useful than presenting one optimistic number.
Where a business sells several products, the calculation becomes more sensitive to the mix. Cases with different prices and variable costs contribute different amounts. A single break-even volume can mislead if the forecast quietly assumes that the highest-margin product will dominate sales. The assumptions should be made visible and revisited when the mix changes.
For example, if the producer adds a second sauce with only G$2,000 contribution per case, a month of 100 cases of each product yields G$600,000 in total contribution: G$400,000 from the first sauce and G$200,000 from the second. That is G$200,000 short of the illustrative G$800,000 fixed cost, even though 200 cases were sold. The earlier 200-case break-even point applies to the original G$4,000-contribution case, not to any combination of 200 cases. With a stable half-and-half mix, average contribution would be G$3,000 and at least 267 cases would be needed to cover G$800,000; actual whole-case mix determines the precise result.
A profitable model can still run short of cash
Break-even analysis focuses on the relationship between revenue and cost for a period. It does not show precisely when customers will pay or when suppliers and staff must be paid. The producer could reach its sales threshold yet have cash tied up in inventory and unpaid invoices. Our Working Capital Explainer examines that timing problem, while the paired Break-Even Calculation Guide turns this concept into an expansion decision.
For an investor, the threshold is most useful when it is connected to evidence. How many units can the plant make? What sales are supported by orders rather than hope? Which costs have been omitted? What happens when price or input cost changes? The answer to those questions matters more than the elegance of a spreadsheet.
The quality of the evidence should match the decision. A signed purchase commitment says more than a retailer’s favourable reaction to samples, while a supplier quotation says more than last year’s ingredient price. Returns, spoilage and unsold cases can make realised contribution lower than the production estimate. If the model relies on every case leaving the plant and being paid for at full price, the apparent buffer may not exist. Break-even analysis is strongest when management shows the assumptions that would change its conclusion and how soon it would know those assumptions were wrong.
Return to the Georgetown producer. The retailers’ interest is encouraging, but it is not yet a business case. At G$10,000 per case, G$6,000 in variable cost and G$800,000 in monthly fixed cost, the operation needs 200 cases to break even. The founder can now compare that target with credible demand, capacity and a downside scenario before signing a lease or buying equipment.
Break-even is not a verdict on whether to invest. It is the point at which a promising idea becomes a question that can be tested.
