How do you Value a Business Based on Turnover in the UK?

Knowing what your business is worth sounds like it should be straightforward. In practice, it's anything but. There are multiple methods of calculating it, each suited to different types of company, and the figure you land on can vary wildly depending on which one you choose.

Valuing a business based on turnover is one of the simpler approaches, and for many small businesses, it's a sensible place to start. This guide explains how it works, when it's useful, and where it falls short. And we’ll also touch on Wise Business account, an all-in-one payments solution ideal for companies of all sizes, especially if you have big plans to go global.

What does it mean to value a business?

A business valuation puts a financial figure on what your company is worth. You might need one if you're thinking about selling, bringing in investors, buying out a partner, or simply taking stock of where things stand.

There's no single correct number. Different methods weigh different factors: revenue, profit, assets, market conditions and the right approach depends on your industry, business size and why you need the valuation in the first place. ¹

What are the main ways to value a business in the UK?

Before diving into turnover-based valuation, it helps to understand the broader landscape. Here are the most common methods:¹

Each method tells a different story. A restaurant with modest profits but strong weekly sales might look very different under a turnover valuation than under a P/E approach.

How to value a business based on turnover

This method is popular because it's relatively quick and doesn't require complex financial modelling. Here's how to do it, step by step.²

Step 1: Calculate your average weekly turnover

Take your total turnover for the most recent financial year and divide it by 52 (the number of weeks). Leave out VAT.

If you have data for more than one year, you can combine the figures for a more representative average. Just remember to divide by the total number of weeks across both periods.

Step 2: Apply your sector multiple

The next step is to multiply your average weekly turnover by a sector-specific multiple. This multiple represents the number of weeks of turnover that's considered a fair value for businesses in your industry.

These multiples vary significantly by sector. A few examples:

• Hair salons and barber shops: typically 10–15 weeks
• Restaurants and cafes: around 20–30 weeks
• Retail shops: varies widely, often 15–25 weeks
• Professional services: can range from 25–50+ weeks depending on recurring revenue

Valuation by turnover formula

The calculation is:

(Annual turnover ÷ 52) × sector multiple = estimated business value

A worked example

Say you run a hair salon with an annual turnover of £75,000.

• Average weekly turnover: £75,000 ÷ 52 = approximately £1,442
• Sector multiple for a hair salon: 12 weeks
• Estimated business value: £1,442 × 12 = £17,307

That gives you a rough starting point. But as you'll see below, it's not the full picture.

Price to earnings (P/E) ratio: an alternative approach

If your business is profitable and has a track record of consistent earnings, a P/E valuation may give you a more accurate figure.

How P/E works

Choose an appropriate P/E ratio based on your business size, sector and growth prospects. Then multiply it by your post-tax profit.¹

The formula is: Post-tax profit × P/E ratio = estimated business value

Typical P/E ratios for small UK businesses:

• Owner-managed businesses: 0 to 2.5
• Small businesses with profits up to £500,000: 2 to 7
• Small enterprises with profits above £500,000: 3 to 10

A worked example

Using the same hair salon earning £75,000 in annual turnover — but this time, let's say post-tax profit is £75,000 (for simplicity) and we assign a P/E ratio of 2.

£75,000 × 2 = £150,000

That's a very different figure from the £17,307 turnover-based valuation. This is exactly why relying on a single method can be misleading.

Is turnover a good way to value a business?

It depends on what you're trying to achieve. Here's a breakdown of the advantages and limitations of this valuation method.

Turnover tells you how much money is coming in. It doesn't tell you how efficiently that money is being used. A business turning over £500,000 with razor-thin margins is worth far less than one turning over £300,000 with healthy profits.

For a more rounded picture, consider combining turnover-based valuation with at least one other method, particularly if you're planning to sell or seek funding, for example, venture capital or angel investment.¹

What affects how much a business is worth?

Beyond the numbers on a spreadsheet, several factors can push a valuation up or down:

• Industry and market conditions: some sectors command higher multiples than others. A tech business with recurring subscription revenue will typically be valued more highly than a traditional retail shop.⁴
• Customer base: a loyal, diversified customer base adds value. Heavy reliance on a handful of clients is a risk.
• Team and management: a strong team that can operate without the owner is more attractive to buyers.
• Reputation and brand: hard to quantify, but a well-known brand with positive reviews carries real weight.
• Growth trajectory: businesses on an upward trend are worth more than those plateauing or declining.
• Location and lease terms: for physical businesses, a prime location with a favourable lease can significantly affect value.

When should you get a professional valuation?

A DIY valuation is fine for getting a ballpark figure, but if you're selling your business, negotiating with investors to secure funding, or going through a legal process , it's worth paying for a professional valuation.

Chartered accountants, business brokers and specialist valuation firms can provide a detailed, defensible figure that takes into account factors a simple formula can't capture.

Frequently asked questions

What is the difference between turnover and profit?

Turnover is the total income your business generates from sales over a given period, before any costs are deducted. Profit is what's left after you subtract all expenses, including wages, rent, materials and tax. A business can have high turnover but low (or even negative) profit.

Can I value my business using turnover alone?

You can use it as a starting point, but it shouldn't be the only method you rely on. Turnover-based valuations don't account for costs, debts, assets or profitability. For a more accurate picture, combine it with other approaches like P/E ratio or asset valuation.

What P/E ratio should I use for my small business?

It depends on your sector, size and growth prospects. Owner-managed businesses typically use a P/E of 0 to 2.5, while small businesses with profits up to £500,000 might use 2 to 7. A qualified accountant or business broker can help you choose the right multiple.

How often should I value my business?

There's no set rule, but an annual valuation can help you track progress, identify areas for improvement and plan ahead. You should also get a fresh valuation before any major event, like selling, seeking investment or restructuring.

Where can I find sector multiples for UK businesses?

Industry bodies, business brokers and specialist valuation firms publish sector multiples. Your accountant may also have access to relevant benchmarking data. Keep in mind that multiples change over time and can vary significantly depending on business size and location.
