A small business should make enough profit to pay the owner fairly, cover tax and unexpected costs, reinvest in the business and still leave a financial buffer. There isn’t one profit percentage that every UK business should aim for.
As a practical planning guide, you might model what your business looks like at 5%, 10% and 20% net profit margins. A 10% net margin means you keep £10 as profit from every £100 of sales after your business expenses have been paid.
But the right target depends on your industry, pricing, overheads and stage of growth. A grocery shop, café, takeaway and mobile phone shop can all have very different cost structures.
The important question isn’t simply, “How much money did we take this month?” It’s how much was left after the real cost of generating those sales?
Key Takeaways
| Question | Simple answer |
|---|---|
| How much profit should a small business make? | Enough to reward the owner, cover risk, fund growth and maintain healthy cash reserves |
| Is 10% profit good? | A 10% net margin can be a useful planning target, but whether it’s good depends on your business |
| Is revenue the same as profit? | No. Revenue is your sales before costs; profit is what’s left afterwards |
| Which profit figure matters most? | Both gross and net profit are useful, but net profit gives a clearer picture of overall performance |
| Should the owner’s wage be counted as a cost? | Usually yes when assessing whether the business itself is genuinely profitable |
| How can businesses improve profit? | Review pricing, stock, staffing, wastage, supplier costs, payment fees and operating expenses |
What Is a Good Profit for a Small Business?
There isn’t a universal number that automatically makes a small business profitable or successful.
One business might generate £500,000 in annual sales and struggle to make £20,000 in profit. Another might turn over £150,000 and produce a much healthier return for its owner.
That’s why profit margin is usually more useful than looking at profit alone.
For planning purposes, consider three scenarios:
- A 5% net profit margin means £5 remains from every £100 of sales.
- A 10% net profit margin means £10 remains.
- A 20% net profit margin means £20 remains.
These aren’t rules or industry guarantees. They’re useful benchmarks for understanding what different levels of profitability would mean for your own business.
A business making a smaller percentage can still be perfectly viable if it has high sales volume and controlled costs.
What Is a Profit Margin?
A profit margin shows how much of your sales revenue remains as profit.
The basic formula is:
Profit margin = Profit ÷ Revenue × 100
For example, imagine your shop generates £30,000 in sales during one month and has £27,000 of total costs.
Your profit is:
£30,000 − £27,000 = £3,000
Your net profit margin is:
£3,000 ÷ £30,000 × 100 = 10%
So for every £1 your business generates in sales, around 10p remains as profit.
That’s much more useful than simply saying, “We made £30,000 this month.”
Gross Profit vs Net Profit
One reason business owners can become confused about profitability is that there are several different profit figures.
The two most useful for most small businesses are gross profit and net profit.
Gross profit
Gross profit is your sales minus the direct cost of the products or services you’ve sold.
For a convenience store, that could mean:
Sales revenue − cost of stock sold = gross profit
If you sell £10,000 of products that originally cost you £6,000:
£10,000 − £6,000 = £4,000 gross profit
Your gross profit margin would be 40%.
Net profit
Net profit goes further.
It takes other operating expenses into account, such as:
- Rent
- Business rates
- Wages
- Utilities
- Insurance
- Software
- Card processing costs
- Marketing
- Accountancy
- Repairs
- Delivery costs
- Other business expenses
A business can have an impressive gross profit margin but still produce very little net profit if its overheads are too high.
That’s why you need to understand both.
How to Calculate Your Small Business Profit Margin
Here’s a straightforward example.
Suppose a small UK retailer has the following monthly figures:
| Item | Amount |
|---|---|
| Sales | £40,000 |
| Cost of stock sold | £24,000 |
| Gross profit | £16,000 |
| Rent, wages and other operating costs | £12,000 |
| Net profit | £4,000 |
The gross profit margin is:
£16,000 ÷ £40,000 × 100 = 40%
The net profit margin is:
£4,000 ÷ £40,000 × 100 = 10%
So the business may appear to make a 40% margin when looking at products alone, but its actual operating profit is much closer to 10%.
If you’re unsure how much you need to sell before your business starts making money, our guide to how to calculate the break-even point for a small business is a useful next step.
Imagine a grocery shop generates £60,000 in monthly sales.
After purchasing its stock, it has £15,000 of gross profit remaining. Rent, wages, electricity, card fees, insurance and other operating costs total £11,500.
That leaves:
£3,500 monthly profit
Its net margin would be approximately:
£3,500 ÷ £60,000 × 100 = 5.8%
The percentage isn’t huge, but because the shop processes a relatively high volume of sales, it may still produce a worthwhile cash profit.
Let’s take an example of a café generates £25,000 in monthly sales.
Ingredients and other direct costs come to £9,000, leaving £16,000 of gross profit.
Its staff, rent, utilities, delivery commissions and other expenses total £14,000.
Net profit:
£2,000
Net margin:
8%
The owner could improve that figure without necessarily finding more customers. Reducing wastage, reviewing menu pricing or controlling staffing costs could make existing sales more profitable.
Or suppose a mobile shop produces £18,000 in sales and finishes the month with £2,700 of profit after its operating expenses.
Its net margin is:
£2,700 ÷ £18,000 × 100 = 15%
The business generates less revenue than the grocery shop, but it retains a larger percentage of each pound sold.
These examples show why turnover alone doesn’t tell you whether a business is healthy.
How Much Profit Should You Aim For?
Rather than choosing an arbitrary percentage, start with what your business actually needs.
Your target profit should ideally allow you to:
- Pay yourself appropriately.
- Cover all normal operating costs.
- Deal with quieter trading periods.
- Replace equipment when necessary.
- Build cash reserves.
- Reinvest in stock, marketing or expansion.
- Handle unexpected expenses.
You can then work backwards.
For example, suppose you want the business to produce £60,000 of annual operating profit.
If your expected annual sales are £600,000, you would need a:
£60,000 ÷ £600,000 × 100 = 10% net margin
You can then examine your pricing and costs to see whether that target is realistic.
Revenue Is Not the Same as Profit
This sounds obvious, but it’s one of the most important distinctions in small-business finance.
Imagine a takeaway generates £20,000 this month compared with £17,000 last month.
Sales are up £3,000. Great.
But what if food costs, staff overtime, delivery commissions and discounts increased by £3,500?
The business has increased its turnover while actually becoming less profitable.
That’s why growing revenue shouldn’t be your only objective.
You need to watch what each sale contributes towards your bottom line.
Our guide to how to reduce business costs without hurting sales covers practical ways to improve this balance.
Should You Pay Yourself Before Calculating Profit?
This is an important point.
If you’re actively working in your business, don’t assume that all the money left at the end belongs to you as profit.
Ask yourself what it would cost to employ someone else to do the work you’re currently doing.
Suppose a business produces £45,000 a year before paying its owner anything. If replacing the owner’s day-to-day work would cost £30,000, the underlying business may only be producing around £15,000 beyond the value of that labour.
This gives you a much more realistic picture of whether the business itself is performing well.
The exact accounting and tax treatment of what you take from the business depends on your business structure, so speak with an accountant if you’re unsure.
What Can Reduce Your Profit Margin?
You don’t always need a dramatic problem for profit to disappear.
Small increases across several costs can gradually eat into your margin.
For example:
- Stock prices increase but retail prices stay unchanged.
- Staff hours aren’t matched to busy periods.
- Products regularly expire or get damaged.
- Portion sizes aren’t controlled.
- Discounts are given without tracking their impact.
- Card processing charges aren’t reviewed.
- Slow-moving stock ties up cash.
- Utility costs rise unnoticed.
- Items are being sold at incorrect prices.
One cost might not seem significant.
Together, they can make a major difference.
If you sell VATable products or services, you also need to understand how VAT affects the money your business actually retains. See our guide on how to calculate VAT for your business for a straightforward explanation.
How to Improve Small Business Profit
More sales can help, but improving profit isn’t always about selling more.
Sometimes the quickest opportunities are already inside the business.
Review your pricing
Costs change.
If suppliers have increased their prices but yours haven’t moved for two years, your margin may be quietly shrinking.
Look at prices product by product rather than applying the same percentage increase to everything.
Reduce unnecessary costs
Review recurring expenses regularly.
That includes software subscriptions, utilities, merchant services, delivery providers and suppliers.
Don’t cut something simply because it costs money. Ask whether you’re receiving enough value from it.
Control stock properly
Overstocking uses cash that could be used elsewhere.
Understocking creates another problem because customers can’t buy the products they want.
Good stock management helps you understand what’s selling, what isn’t and where money is being tied up.
Watch wastage
This matters particularly in cafés, restaurants, takeaways and grocery businesses.
If £300 of stock is being wasted every week, that isn’t simply a stock issue.
It’s a profit issue.
Review your payment costs
Card payments are a normal part of running many modern businesses, but the cost still needs monitoring.
Small differences in payment charges can become more noticeable as transaction volume grows.
Track performance regularly
Don’t wait until the end of the financial year to discover whether you’ve made money.
Review sales, gross profit, expenses and stock performance throughout the year.
The earlier you spot a problem, the easier it usually is to investigate.
How EPOS Can Help You Understand Profit
A modern EPOS system should do more than process transactions.
It can give you better visibility over what’s happening inside your business.
For example, an EPOS system can help you track:
- Daily and weekly sales
- Product performance
- Stock movement
- Gross profit
- Discounts
- Refunds
- Staff activity
- Busy trading periods
- Slow-moving products
- Sales across different locations
Suppose your total sales look healthy but one product category has a very poor margin.
Without product-level reporting, you might not notice.
With better sales and stock data, you can investigate individual categories, products or trading periods instead of relying on guesswork.
If you’d like to understand the technology in more detail, read our guide explaining what an EPOS system is and how it works.
When Is a Low Profit Margin a Problem?
A low profit margin doesn’t automatically mean your business is failing.
Some businesses deliberately operate on smaller margins because they sell large volumes. Others accept lower profit temporarily while opening a new location, purchasing equipment or building their customer base.
The warning sign is when there isn’t enough profit to support the business comfortably.
For example, you may have a problem if:
- Cash is regularly running short.
- You can’t pay yourself properly.
- Supplier payments are continually delayed.
- Unexpected bills cause serious difficulty.
- Sales are growing but cash isn’t.
- There’s no money available to reinvest.
- You rely on borrowing to cover normal operating expenses.
Look at the trend as well as the percentage.
A business moving from a 3% margin towards 7% may be improving. Another moving from 12% towards 7% may need attention even though both businesses currently have the same margin.
Focus on Profitable Sales, Not Just More Sales
So, how much profit should a small business make?
There’s no single percentage that works for every business. Your target should reflect your industry, cost structure, workload, growth plans and the return you expect from running the company.
Instead of asking whether your sales are high enough, look at what happens after the sale.
How much did the stock cost?
How much did you spend making the sale?
What overheads need covering?
And most importantly, how much is actually left?
Once you understand those numbers, you can make much better decisions about pricing, staffing, stock and future growth.

Frequently Asked Questions
What is a good profit margin for a small business in the UK?
There isn’t one profit margin that’s suitable for every UK small business. Your ideal margin depends on your sector, operating costs, pricing and sales volume.
Instead of relying on a universal benchmark, calculate your current net margin and compare it with your previous performance and your financial goals.
Is a 10% profit margin good for a small business?
A 10% net profit margin can represent a useful planning target.
For example, a business generating £300,000 in sales with a 10% margin would produce £30,000 in profit. Whether that’s sufficient depends on how much time, capital and financial risk are required to operate the business.
Is 20% profit good for a small business?
A 20% net margin would mean retaining £20 from every £100 of revenue after relevant business expenses.
That can represent strong profitability for many business models, but you should still consider cash flow, tax, owner remuneration and future investment requirements.
What’s the difference between gross profit and net profit?
Gross profit is your sales minus the direct cost of producing or purchasing what you’ve sold.
Net profit takes wider business expenses into account, such as wages, rent, utilities, insurance and other operating costs.
How do I calculate my small business profit margin?
Use:
Profit ÷ Revenue × 100
If your business makes £5,000 profit from £50,000 of revenue:
£5,000 ÷ £50,000 × 100 = 10%
Your profit margin is 10%.
Can a business have high sales but low profit?
Yes.
A company may generate substantial revenue while having high stock costs, wages, rent or other expenses. That’s why turnover should always be considered alongside profit and cash flow.
How can I increase my business profit without increasing sales?
Start by reviewing pricing, supplier costs, wastage, staffing, slow-moving stock, card processing costs and unnecessary operating expenses.
Improving the margin on the sales you’re already making can sometimes have as much impact as increasing revenue.
