Can This Business Actually Make Money?

Can This Business Actually Make Money?

Short answer: work out one number first. The contribution on a single sale, after everything it costs to deliver and everything it costs to acquire. Then divide your monthly fixed costs by it. That gives you the number of sales you need to break even. 

If that number is larger than the number of customers you could realistically serve or reach in a month, the business does not work, and no amount of marketing will change it.

Most people run this calculation after launching. It takes about forty minutes, and it belongs before you spend anything.

Three break-evens, not one

Founders talk about break-even as though it were a single milestone. There are three, and they arrive months apart.

Unit break-even. Does one sale make money after delivery costs? If it doesn’t, growth simply accelerates your losses.

Business break-even. Do total contributions cover fixed costs? This is what people usually mean by the term, and it’s the point where the business stops consuming cash.

Founder break-even. Does the business pay you enough to live on? This is the one that decides whether you can keep going. Businesses that reach business break-even but never founder break-even are jobs that pay less than a job, and they can persist for years because the accounts look perfectly healthy.

Plan for all three, and put a target date against each.

Building the model

Step 1: Revenue per sale

Not your price, but your realised price. Deduct discounts, promotional pricing, payment processing fees, marketplace commission and refunds.

A £50 product sold on a marketplace charging 15%, with 3% payment fees and a 6% return rate, realises roughly £50 × 0.85 × 0.97 × 0.94, which comes to £38.40. That’s a 23% reduction before you have made anything at all. It’s also where most e-commerce plans quietly go wrong.

Step 2: Cost of delivery

Everything that exists only because that sale happened:

• Materials, ingredients, components, wholesale cost
• Packaging and shipping
• Direct labour, including your own time, valued at what you would have to pay someone else to do it
• Subcontractors, and any per-job licence or software cost
• Consumables, travel, waste and spoilage
• Warranty, rework and support attributable to that sale

Include your own labour. A business that is only profitable because you work unpaid isn’t profitable, it’s subsidised, and it can never be delegated, sold or scaled.

Step 3: Contribution margin

Contribution margin = realised revenue minus cost of delivery Contribution margin %       = contribution ÷ realised revenue

This is what each sale contributes towards fixed costs and profit. Everything downstream depends on it.

Rough sector expectations, worth checking against your own market. Be suspicious if you land far above them.

If your model shows 80% margins in a 35% category, you have missed a cost somewhere. Go back and find it.

Step 4: Customer acquisition cost

Total spend on acquiring customers divided by customers acquired. Include ad spend, referral fees, any marketplace fees not already counted, sampling, the discount you offered to win the first order, and the item everyone leaves out: the value of your own time spent selling.

Contribution after acquisition = contribution margin minus acquisition cost

That figure is the real one. A £120 contribution with a £140 acquisition cost describes a business that loses money faster the better its marketing works.

Step 5: Fixed costs

Everything you pay whether or not you sell anything. Rent, insurance, software subscriptions, accountancy, phone and internet, vehicle costs, loan repayments, salaried staff, memberships, and your own minimum drawings.

Step 6: The break-even calculation

 Monthly sales needed = fixed costs ÷ contribution after acquisition

Worked example A: a small-batch bakery selling online and at markets

Fixed costs come to £1,105 a month: kitchen hire at £650, insurance £45, software £60, market pitch fees £280 and accountancy £70.

Break-even = £1,105 ÷ £5.53 = 200 orders a month, or about 46 a week.

 

Now ask the question the model exists to raise. Can this founder produce, pack and deliver 46 orders a week alongside two market days? At 0.6 hours of direct labour each, that’s 28 hours of production before any admin, buying, market attendance or marketing. It’s possible, but it is close to full time. And at break-even the founder is being paid only the £7.80 per order of direct labour, which comes to roughly £1,090 a month.

The model isn’t broken, but it is tight, and it points straight at the lever. Contribution sits at 30% because delivery is subsidised and labour per order is high. The options are to raise average order value through bundles or a subscription, to charge properly for delivery, or to cut labour per order through batching. Change any one of those and everything downstream moves, which you can only see because the model exists.

Worked example B: the same founder’s alternative, wholesale to cafés

 Break-even on £1,105 of fixed costs = 13 weekly orders, meaning 13 café accounts.

 

Thirteen accounts against two hundred consumer orders a month. Same kitchen, same product, radically different business. Wholesale trades a lower headline price for far lower acquisition and fulfilment cost per pound of revenue.

There is a serious catch, and it’s the 30-day payment terms. Thirteen accounts at £180 a week is roughly £10,140 a month of revenue, of which a full month may be outstanding at any moment. This version of the business needs around £10,000 of working capital simply to run at break-even. The direct-to-consumer version needs almost none, because customers pay before delivery.

Profit and cash are separate questions. Model both, every time.

How long until you make money?

Realistic ranges from launch to business break-even:

Founder break-even usually arrives six to eighteen months after business break-even. Build your personal runway against that second date rather than the first.

Three things compress the timeline more than anything else: selling before you build, taking pre-payment or deposits, and acquiring customers through referral and existing relationships rather than paid channels. All three are decisions available to you now, not matters of luck.

Stress-testing the model

Run four scenarios. It takes about ten minutes in a spreadsheet and prevents most disasters.

The fourth one surprises people. Growth consumes cash: more stock, more staff, more equipment, longer receivables. Businesses fail from growing too fast at least as often as from failing to grow.

Six ways plans overstate profit

Unpaid founder labour. Corrected by pricing your own hours into the model.

Assuming full utilisation. No service business bills every available hour. Assume somewhere between 55 and 70%, and be pleased if you beat it.

Ignoring the cost of acquiring the customer. The single most common error in the whole exercise.

Marginal costing on everything. “The next unit only costs materials” holds right up until you need another oven, another van or another person.

Forgetting tax and irregular costs. Tax, insurance renewals, equipment replacement and accountancy are annual costs that need dividing by twelve and carrying monthly.

Assuming your price holds. New businesses discount to win early work far more than they intend to. Model your realistic average, not your rate card.

The verdict

Your business plausibly makes money if all five of these hold:

• Contribution after acquisition is positive, and ideally above 25% of realised revenue
• Break-even volume is under half what you could realistically deliver at capacity
• Time to business break-even is shorter than your funded runway
• The pessimistic scenario is survivable rather than merely unpleasant
• The business reaches founder break-even within a period you can personally sustain

Failing one of those doesn’t necessarily mean no. It means you have found the specific thing that has to change: the price, the delivery cost, the channel, the customer or the model itself. That’s a far more useful output than a yes.

Frequently asked questions

What contribution margin is high enough?

Above 25% of realised revenue after acquisition costs is a workable floor for most small businesses, and above 40% gives you room to make mistakes. What matters more than the percentage is the absolute contribution per sale against how many sales you can physically handle. A 60% margin on a £12 product needs volume you may not be able to reach; a 30% margin on a £900 job may only need a handful of customers a month.

Should I really count my own time as a cost?

Yes, at the rate you would pay someone else to do the same work. Leaving it out produces a model that looks profitable and can never be handed over, which means you have bought yourself a job with unlimited hours rather than built a business. If including your labour turns the model negative, that is the finding, and it usually points at pricing or at how long delivery takes.

How do I estimate acquisition cost before I have any customers?

Use three rough proxies and take the worst. Look at what a comparable business spends per customer, calculate what a paid channel would cost using published click prices and a conservative 2% conversion, and price your own selling time at your hourly rate multiplied by the hours a typical sale takes. Then revise it after your first ten customers, because the real figure is almost always higher than the estimate.

What if my break-even volume looks impossible?

Then something structural has to change, and there are only four levers: raise the price, cut delivery cost, cut acquisition cost, or reduce fixed costs. Work out which single lever moves break-even furthest, since it is rarely the one founders expect. In the bakery example above, charging properly for delivery does more than any plausible increase in marketing.

Is a business that only breaks even worth continuing?

It depends on which break-even you have reached and where the trend is heading. Sitting at business break-even in month eight with rising volume and stable costs is normal and fine. Sitting there in month thirty with flat volume means the model has settled and will not improve on its own. The question to ask is whether anything in the next quarter will change the arithmetic, rather than whether you can hold on a bit longer.

How often should I rebuild the model?

Rebuild it monthly for the first year, then quarterly once the numbers stop moving much. Replace estimates with actuals as they arrive, one line at a time. Most founders build the model once, use it to justify launching, and never open it again, which wastes the thing it is actually good for: catching a cost drifting upward while there is still time to respond.

Why does my profitable business keep running out of cash?

Because profit and cash arrive on different schedules. You pay for stock, materials and labour before customers pay you, and any business offering payment terms is effectively lending money to its customers. Model a monthly cash position alongside the profit model, and hold enough working capital to cover the gap between when money leaves and when it returns. That gap closes businesses that are profitable on paper.

Does this model still work for subscription or repeat businesses?

The structure holds, with one addition: acquisition cost is recovered across the whole customer lifetime rather than a single sale. Calculate contribution per month, multiply by the average number of months a customer stays, and compare that total against acquisition cost. A useful rule of thumb is that lifetime contribution should be at least three times acquisition cost, and that you should recover the acquisition cost within twelve months.
