Quick answer: Business turnover is the total revenue a company generates from its core trading activities over a set period – usually a financial year. To calculate it, add up all sales of goods or services before any deductions. Turnover differs from profit, which accounts for costs.
Turnover is one of the most talked-about figures in business – and one of the most misunderstood. Ask two small business owners what it means, and you might get two different answers.
So let’s clear it up. This guide explains exactly what turnover means, why it matters, and a turnover calculator to work out yours.
Whether you’re filing a tax return, applying for a loan, or just trying to get a clearer picture of your finances, understanding turnover is a good place to start.
What is business turnover?
Turnover is the total amount of money your business brings in from selling goods or services during a specific period. It’s sometimes called revenue, income, or sales, and it’s typically measured over a financial year.
The key thing to remember is that turnover is calculated before any costs are taken out. That means it doesn’t account for expenses like wages, rent, or the cost of materials.
Here’s a simple way to think about it: if your business sells 500 products at £20 each, your turnover is £10,000 – regardless of what it cost you to make or sell those products.

How do you calculate turnover?
Want to work out your turnover on your own? The formula for turnover is straightforward:
Turnover = Number of units sold × selling price per unit
Or, if you offer multiple products or services:
Turnover = Total value of all sales made in the period
What to include in your turnover calculation
When working out your turnover, count:
- sales of products or goods
- fees charged for services
- income from contracts or projects completed during the period
What not to include
Don’t include:
- VAT collected on sales (this belongs to HMRC, not you)
- income from selling business assets, like equipment
- any refunds or returns (deduct these from your total)
- grants or investment income, which are usually recorded separately
What’s the difference between turnover and profit?
This is where a lot of people get confused. Turnover and profit are related, but they’re not the same thing.
- turnover is your total sales income before costs
- gross profit is turnover minus the direct cost of producing your goods or services (like materials or manufacturing)
- net profit is what’s left after all your costs – including overheads like rent, utilities, and wages – have been deducted
So a business can have high turnover and still make very little profit. If your costs are eating into your revenue, your net profit margin will be low – even if your sales figures look impressive.

“Let’s say there’s a product you can sell for £100, and you’ve got a product you could sell for £50. On a quick overview, we might think that you should go for the £100 product and sell as many of those as you can.
“But what if the margin on that is much lower? What if the profit you make on that £100 product is only £5 once you’ve covered all your costs? And the product that’s at £50 – what if your margin is huge on that and you’re actually making a huge £40 on every sale? That then adjusts where you’re going to place your efforts and can actually shape your whole business strategy.”

Turnover vs annual revenue: is there a difference?
In most cases, no. Turnover and annual revenue mean the same thing – the total income generated from sales during the year. The term “annual revenue” is more common in the US, while “turnover” is more widely used in the UK.
That said, in some industries – particularly retail and manufacturing – “stock turnover” refers to something different: how quickly a business sells through its inventory. So it’s always worth checking the context.
Why does turnover matter for small businesses?
Turnover affects your business in more ways than just showing how much you’ve sold. Here are some of the reasons it matters.
Tax obligations
Your turnover determines whether you need to register for VAT. The current VAT threshold in the UK is £90,000 a year (as of 2024). If your turnover goes above this, you must register with HMRC. You can keep track of the official Gov UK VAT registration thresholds here.
Self-employed people and sole traders also need to report their turnover when completing a Self Assessment tax return. HMRC uses this figure – alongside your expenses – to work out your taxable profit.
Business loans and funding
Lenders often look at your turnover when deciding whether to approve a loan or credit facility. A consistent or growing turnover can show your business is trading healthily – which makes you a lower-risk borrower.
Benchmarking performance
Tracking your turnover over time helps you spot trends. Is revenue growing year on year? Is there a quiet season that reliably dips? Knowing this helps you plan ahead, manage cash flow, and make smarter decisions about staffing, stock, and investment.
What is a good turnover for a small business?
There’s no single answer here, because it depends heavily on your industry, business model, and how long you’ve been trading. What matters more than the absolute number is your profit margin – how much of your turnover you actually keep after costs.
According to the Office for National Statistics (ONS), small businesses (those with between 0 and 49 employees) contributed £1,880,023 in turnover to the UK private sector.
Rather than chasing a specific turnover figure, focus on understanding your costs and making sure your revenue covers them – with enough left over to grow.
The bottom line: know your numbers
Turnover is a foundational business metric. It won’t tell you everything about your financial health – but it’s the starting point for understanding your profitability, your tax obligations, and how your business is growing over time.
Once you know your turnover, you can start to dig into your costs, calculate your margins, and make more confident decisions about where to take your business next.
And if you’re a small business owner looking to protect what you’ve built, it’s worth making sure your business insurance covers you as your revenue grows.

Frequently asked questions about business turnover
Is turnover the same as income?
Not exactly, turnover refers specifically to revenue from trading – selling goods or services. Income can be a broader term that includes other sources of money coming into the business, such as investment returns or grants.
Does turnover include VAT?
No, turnover is calculated excluding VAT. The VAT you collect on behalf of HMRC doesn’t belong to your business, so it’s not counted as part of your revenue.
How do I report turnover on my tax return?
If you’re self-employed or a sole trader, you report your turnover in the Self Employment section of your Self Assessment tax return. You then deduct allowable expenses to arrive at your taxable profit. Limited companies report turnover in their annual accounts filed with Companies House.
What’s the difference between turnover and cash flow?
Turnover measures the value of sales you’ve made, while cash flow tracks the actual movement of money in and out of your business. You can have high turnover but poor cash flow – for example, if customers are slow to pay their invoices.
Can turnover go down even if I’m selling more?
Yes – if you reduce your prices, you could sell more units but bring in less total revenue. This is why it’s important to track both your sales volume and your average selling price.
