Break-Even and Working Capital: When Will Your Business Pay for Itself, and How Much Cash Does It Need?

After "will people buy?", the most important question a new business owner asks is "when will the business pay for itself?". The answer is not a guess. It is a simple calculation once you know three numbers: the selling price, the variable cost per unit and the monthly fixed costs. This article walks through the calculation step by step, with a calculator you can run on your own figures, then turns to the question many owners skip: how much money has to stay tied up in the business for it to keep running, which is what working capital means.

What is the break-even point?

The break-even point is the sales volume at which revenue equals total costs, so there is neither profit nor loss. It rests on the idea of contribution margin: what is left of a unit's selling price after its variable cost, which is the amount each unit contributes first to covering fixed costs and then to profit¹.

Variable costs are everything paid with each sale: materials, packaging, delivery if you pay for it, and the payment gateway's or platform's commission. Fixed costs are what you pay every month even if you sell nothing: rent, wages, the employer's share of social insurance, utilities, ongoing marketing and accounting. The most common mistake is putting an item in the wrong bucket, for example treating the wages of a permanent team as a variable cost, which makes break-even look lower than it really is.

Put each cost in the right place

Some items are obvious; others sit in between. The table below shows the practical classification we use in studies, and the rule behind it is simple: ask yourself "if I sold twice as much next month, would this item double?". If yes, it is variable; if it stays the same, it is fixed; if it rises by less, it is semi-variable.

Semi-variable items are handled by splitting them: the part paid no matter what goes into fixed costs, and the part that rises with sales goes into the unit cost. If the business will need an extra worker at a certain volume, break-even jumps at that volume, and the study should show this clearly rather than hide it in an average.

Calculate it on your numbers

The calculator below is filled in with the coffee kiosk example from our feasibility study guide for Egypt 2026. Replace the figures with your own and the results update instantly.

Example: a single product

In the coffee kiosk example, a cup sells for EGP 45 and its variable cost is EGP 18, so the contribution margin is EGP 27, or 60% of the price. Monthly fixed costs are EGP 45,000 including the employer's social insurance share. So:

• Break-even = 45,000 ÷ 27 ≈ 1,667 cups a month, roughly 56 cups a day.
• Break-even revenue = 45,000 ÷ 60% = EGP 75,000 a month.
• If expected sales are 3,000 cups a month, the margin of safety = (3,000 − 1,667) ÷ 3,000 ≈ 44%. Sales could fall by about 44% before the business starts losing money each month.
• Monthly operating profit at 3,000 cups = 3,000 × 27 − 45,000 = EGP 36,000.

You will notice the calculator shows the investment costs (EGP 310,000) paid back after about 9 months, while the guide shows payback in month 15. That is not an error. The calculator assumes sales are steady from day one, whereas the monthly table includes a set-up period with no sales, then months where sales start low and build up gradually, and adds the losses of those months to what has to be recovered. That is why we treat the calculator's figure as the optimistic minimum and the monthly table's figure as the realistic one.

Example: a service with almost no direct cost

In services the owner delivers personally, such as consulting or design, variable cost can be close to zero, so almost the whole price is contribution margin. Take a consulting session priced at EGP 1,500 and monthly fixed costs of EGP 30,000 (the owner's pay, social insurance, a co-working desk, marketing, accounting and software):

• If the owner delivers each session: break-even = 30,000 ÷ 1,500 = 20 sessions a month.
• If a freelance consultant is paid EGP 600 per session: the contribution margin is EGP 900, and break-even = 30,000 ÷ 900 ≈ 34 sessions a month.

The lesson is that services are not cost-free. If your time is what you sell, your monthly capacity sets the ceiling. Twenty sessions a month may be achievable for one person; thirty-four may not. The choice between delivering yourself and bringing in others changes break-even considerably.

Example: more than one product

Most businesses sell more than one product. In that case you use the average contribution margin weighted by each product's share of sales. Suppose the kiosk sells coffee (margin EGP 27, 70% of units sold) and pastries (price 30, variable cost 15, so margin EGP 15, 30% of units):

• Weighted contribution margin = 70% × 27 + 30% × 15 = 18.9 + 4.5 = EGP 23.4 per unit.
• Break-even = 45,000 ÷ 23.4 ≈ 1,923 units a month, about 1,346 cups of coffee and 577 pastries.

Notice that adding a lower-margin product raised break-even from 1,667 to 1,923 units, even though it adds revenue. The extra product helps when it brings in new customers or raises the average bill, not when it replaces a higher-margin product.

Three points not to confuse

The simple formula gives you the sales volume needed to break even, but it does not tell you when you will get there. New businesses start with a set-up period and then a gradual build-up in sales, so pinning down the break-even month and the capital required needs a monthly cash flow table, not a single formula.

Accounting break-even and cash break-even

Another difference appears when the business has equipment that wears out or a loan being repaid. Depreciation, which spreads the cost of equipment over its useful life, is an accounting cost but does not leave as cash each month. Conversely, the monthly loan instalment leaves as cash, but the part that repays principal does not appear as an expense in the income statement; only the interest does.

An illustration: a workshop has accounting fixed costs of EGP 60,000 a month, including EGP 5,000 of depreciation, and repays EGP 4,000 of loan principal each month. Cash fixed costs = 60,000 − 5,000 + 4,000 = EGP 59,000. With a contribution margin of EGP 100 a unit, accounting break-even is 600 units and cash break-even is 590. The gap is small here, but it grows in equipment-heavy businesses or those financed with large instalments, and cash break-even can exceed accounting break-even when principal repayments are larger than depreciation. A bank cares about cash break-even, because its question is whether cash will cover the instalment. We cover this in detail in our guide to feasibility studies for bank loans.

How to lower your break-even

There are only three levers, and it helps to compare their effect on your numbers before choosing. In the kiosk example (original break-even 1,667 cups):

In businesses with a high contribution margin, price has a bigger effect than variable cost, because every pound added to the price goes straight to the margin. But price increases have limits set by competitors and customers, so read this table together with the competitor section of your study. Cutting fixed costs has a certain effect, but it can cost quality or capacity, for example starting with one employee instead of two.

What if? Test how sensitive your numbers are

Break-even alone is not enough, because the numbers behind it are estimates. The more important question is what happens to profit if one of them turns out worse than expected. In the kiosk example, base monthly profit is EGP 36,000 at 3,000 cups:

The discount is the striking row. Cutting the price by 10% cuts profit by 37.5%, and to make up for it you would need to sell 3,600 cups instead of 3,000, a 20% increase in sales. That is why any promotion or discount should be costed before launch: will it bring in more extra sales than it needs to cover the margin it gives away?

The third scenario is not far-fetched in Egypt, because material prices move with inflation and the exchange rate. If your inputs are imported or priced in dollars, test a larger rise in variable cost, and write down in your study how you will respond: will you pass it on in your price, and after how many months?

Working capital: the money tied up in the cycle

Working capital is the difference between current assets, such as cash, stock and amounts customers owe you, and current liabilities, such as amounts owed to suppliers². In a business owner's terms, it is the money that has to be available so you can buy goods today, wait until you sell them, and then wait until the customer pays.

Businesses that sell to consumers for cash, like the kiosk, need little working capital: a few days of stock, and the customer pays immediately. Businesses that sell to companies on credit or hold large stocks, such as distribution, supply contracts and manufacturing, can need more working capital than the set-up costs themselves.

The cash conversion cycle

The simplest way to work out how many days your money stays locked up is the cash conversion cycle: inventory days + customer collection days − supplier payment days².

An illustration for a distribution business: monthly sales of EGP 300,000 with cost of goods of EGP 240,000. Goods sit in the warehouse for 45 days on average, customers pay after 60 days, and suppliers are paid after 30 days:

The cash conversion cycle here is 75 days (45 + 60 − 30). More importantly, the working capital required, EGP 720,000, is more than two full months of sales. A business with these numbers can be profitable on paper and still stall if this amount is not set aside from the start, because money goes out to suppliers before it comes back from customers.

How to reduce working capital

• Shorten collection: in the example, cutting customer collection from 60 to 30 days lowers working capital by EGP 300,000. A small early-payment discount can be cheaper than financing that amount.
• Ask suppliers for longer terms: every extra 15 days from suppliers frees EGP 120,000 in the example.
• Cut inventory days: order smaller quantities more often, and clear slow-moving lines.
• Start with customers who pay cash or in advance until your capital grows, then extend credit gradually.

How much funding do you really need?

When you ask "how much capital do I need?", the answer is not the set-up cost alone. The funding that must be available before opening has four parts:

1. Investment costs: equipment, fit-out, decoration, licences and the rent deposit.
2. Set-up period expenses: rent and wages paid before the first sale.
3. Early-month losses: the gap between expenses and sales until operating break-even.
4. Working capital: the stock and customer balances that grow as sales grow.

Together these show up in the cash flow table as the deepest point of the cumulative balance. In the kiosk example, investment costs are EGP 310,000 but the deepest point is EGP 386,500, so the business needs about EGP 76,500 more to cover the set-up period and early losses. It is wise to add a reserve on top for sales arriving later than expected; in the guide we suggested a reserve of two months of fixed costs (EGP 90,000), bringing the funding required to EGP 476,500, about 54% more than the investment costs. An owner who raises only EGP 310,000 will run out of cash before the business reaches its deepest point, even if the idea works.

Egyptian factors that raise working capital needs

Inflation: annual urban headline inflation was 13.9% in September 2026³. When prices rise, you need more money to buy the same quantity of stock, so working capital rises even if sales do not. Build this into years two and three of the study.

E-invoicing for business-to-business sales: the Egyptian Tax Authority defines an e-invoice as a signed electronic document validated in real time, and the system was rolled out to companies in phases by successive decisions⁴. If you will sell to companies, check early where your activity stands, set up invoicing from the start, and count the time to issue and review invoices as part of your collection cycle.

Deferred payment in supply contracts: selling to companies and large institutions usually comes with long payment terms. Before accepting a large contract, work out how much of your money it will lock up and for how many days, and whether your capital can carry it. Do not count on late-payment interest to compensate you: statutory delay interest under the Civil Code is 4% in civil matters and 5% in commercial matters⁵, while the Central Bank's overnight deposit rate is 19%³. Financing a late payment will cost you far more than any delay interest you might collect, so agreeing payment terms in writing before you deliver matters most.

Common mistakes in break-even and working capital

1. Treating fixed wages as a variable cost, which makes break-even look lower than it is.
2. Forgetting the employer's social insurance share in fixed costs.
3. Using a simple average contribution margin instead of one weighted by each product's share of sales.
4. Confusing operating break-even with payback, and assuming the business has "recovered its capital" just because it has started making a monthly profit.
5. Treating capital as equal to set-up cost, and ignoring working capital in businesses that sell on credit or hold stock.
6. Assuming customers always pay on time, with no allowance for delays.
7. Ignoring capacity: a break-even above what you can produce or deliver means the business cannot make a profit in its current form.

How these numbers appear in a Kleverz study

The detailed Kleverz study calculates everything explained here on your own project's numbers: monthly break-even revenue and the number of units of each product or service you need to sell, then a month-by-month cash flow for the first 12 months and a yearly summary over three years, identifying the operating break-even month, the deepest cash point and the payback month. The study tests optimistic and pessimistic scenarios and sets out every assumption behind the calculation so you can review and adjust it. If you enter your price, direct cost and expected sales volume in the form, the figures are built on your project rather than on general averages.
