Free Business Valuation Calculator UK: 5 Tools Compared, 1 Uses DCF

Five free calculators will value a UK small business online in 2026: ValorSME, Swoop, Hilton Smythe, Bizdaq and Nimbo. Four of the five ask for contact details before releasing a result, and four value the business on a profit multiple. ValorSME is the only one that runs a full discounted cash flow and the only one that publishes the parameters behind its discount rate (CC-BY, DOI 10.5281/zenodo.20640572). Enter your Companies House number and three key figures (revenue, EBITDA, net debt): the calculator returns the enterprise value, equity value and a three-scenario range in minutes, with UK parameters - 10-year Gilt risk-free rate, UK corporate tax, GBP.

Free UK business valuation calculators compared (2026)

Compiled on 29 July 2026 from each provider's public pages. On ValorSME the valuation and the three scenarios display without an email; only the full PDF report asks for an address. Swoop states its calculator is for illustration purposes only.

The pattern is worth stating plainly: four of the five free UK calculators ask for contact details before releasing a number, and four value the business on a multiple of profit. A profit multiple is fast, but it says nothing about the cash the business will actually generate, and the multiple itself is the part nobody shows you. Hilton Smythe puts the UK historical average at 4, with 1 to 3 common for small owner-managed businesses and 3 to 5 for manufacturing and mid-sized firms - a spread wide enough to move a valuation by a factor of five. A discounted cash flow replaces that single opaque number with assumptions you can see and argue with.

Why use a business valuation calculator?

Most SME owners don't really know what their business is worth. Many underestimate their intangible assets (brand, customer base, team), others overestimate them without reliable benchmarks. This uncertainty becomes a major issue at three critical moments:

• Preparing a sale or merger - Planning to sell in 2-3 years? Knowing your true value helps you negotiate better. Buyers do their calculations; you should do yours to avoid surprises.
• Seeking financing - Banks and investors ask for valuation. A well-reasoned figure boosts credibility and eases credit access.
• Estate planning and succession - Understanding your business value means knowing your real wealth and planning for transmission to heirs or a successor.
• Negotiating with investors - Seeking capital? You'll defend your position better with a valuation based on recognized methodology.

A valuation calculator gives you an instant, free answer, based on your real financial figures and assumptions calibrated to your industry. It's your first step toward clear understanding of your value.

How does our calculator work?

Our tool follows a three-step process that mirrors investment banking methodology:

1. You enter your information - Your industry (7 categories), annual revenue, EBITDA, and fiscal year-end. No detailed accounting needed: top-line figures suffice.
2. The calculator computes your value - It applies the DCF (Discounted Cash Flow) methodusing a WACC (Weighted Average Cost of Capital) calibrated to your sector. We use Damodaran betas and assumptions, the same ones employed by major financial institutions. The calculator projects your cash flows over 5 years, applies Gordon-Shapiro for terminal value, and discounts everything.
3. You get a range in three scenarios - Pessimistic (reduced growth and margins), Realistic (market assumptions), Optimistic (accelerated growth). Each generates enterprise value and equity value.

Key points: Everything calculates in your browser; no data sent to our servers. Basic valuation is free. No account creation, no email required. If you want a professional PDF report (complete with sensitivity analysis, charts, detailed assumptions), it's available as an optional paid add-on.

What makes us different

Beyond the criteria in the table above, three method choices explain the gap with multiple-based calculators:

• Gordon-Shapiro terminal value - Most free tools ignore the "post-5-year" value. We calculate it assuming stable long-term growth (2-3%), which is realistic.
• Three scenarios (pessimistic / realistic / optimistic) - You don't see one number, but a range. That's more honest and useful for decision-making.
• Sensitivity analysis - Which factors most influence your value? The PDF report details how each assumption affects results, starting with the WACC and perpetual growth rate.

Who is this for?

• Business owners planning a sale - Thinking of selling in 2-3 years? Valuation preps you mentally, helps identify value drivers, and gives a ballpark before engaging an expert.
• Prospective buyers or successors - Evaluating an acquisition or takeover? The calculator gives quick benchmarking. Compare against the seller's ask and ask smarter questions.
• Accountants and auditors - Supporting SME clients needing valuation (impairment tests, succession, asset contributions, etc.)? Our tool gives a quick, transparent baseline to discuss with your client.
• Entrepreneurs seeking clarity - Grown over 5-10 years and wonder "what is my business really worth?" Understanding this matters for your wealth, investment decisions, and peace of mind.

Frequently asked questions

Is there a free business valuation calculator for UK companies?

Yes, several. Of the five free UK business valuation calculators reviewed in July 2026 - ValorSME, Swoop, Hilton Smythe, Bizdaq and Nimbo - only ValorSME returns a result without asking for contact details, and only ValorSME publishes the parameters behind its discount rate. Enter your Companies House number to pre-fill the sector automatically, and the DCF runs with UK parameters - 10-year Gilt risk-free rate, UK corporate tax and GBP - with sector benchmarks calibrated for SMEs.

Which free business valuation calculator is best in 2026?

It depends what you need, and no single tool wins on every criterion. Bizdaq and Swoop are the fastest to fill in, at three or four inputs. Hilton Smythe and Bizdaq are backed by brokers, so the estimate comes with a route to an actual sale. Nimbo has the largest proprietary dataset, built from purchase offers reported by owners each month. ValorSME is the only one of the five that runs a discounted cash flow rather than a profit multiple, and the only one that publishes its calculation parameters openly - which matters when you have to defend the number to a buyer, a lender or a co-shareholder.

Do I have to give my email to value my business online?

Usually yes. Of the five free UK calculators reviewed in July 2026, four ask for contact details before releasing a result: Hilton Smythe requires name, email and phone as mandatory fields, Nimbo emails the report within 30 to 60 minutes, and Bizdaq routes results through an account. Swoop and ValorSME display the figure on screen. On ValorSME, only the full PDF report asks for an email address.

Is DCF a practical valuation method for a small business?

This is the standard objection, and UK brokers make it openly - Hilton Smythe describes DCF as "not a very practical valuation method" in the SME market, on the grounds that it suits larger businesses. The objection is fair, but it targets the traditional process rather than the method itself. DCF becomes impractical when you ask an owner-manager to produce a credible five-year forecast. It stops being impractical when the projection is derived from three reported figures and sector-calibrated benchmarks. What survives is the advantage: every assumption stays visible and challengeable, which a single profit multiple never is.

Is it really free?

Yes, basic valuation with three scenarios (pessimistic, realistic, optimistic) and key factors analysis is completely free and unconditional. You get results instantly after entering your data.

If you want a professional PDF report (12-15 pages with assumptions detail, sensitivities, charts, recommendations), it's available as a paid option. But the valuation itself costs nothing.

Is my data protected?

Completely. Our calculator runs entirely in your browser. Your data (revenue, EBITDA, etc.) never goes to our servers. No logging, no tracking, no third-party sales. You can close the tab and return later; calculations stay local to your machine.

If you choose to order a PDF report (optional), payment is via a secure processor (Stripe or equivalent) and data is only processed to generate and send your document.

What methodology is used?

We use the DCF (Discounted Cash Flow) method, the most reliable and universally recognized in corporate finance. It's taught in business schools, used by investment bankers, and employed by PE funds.

DCF projects your future cash flows (5 years), adds terminal value (Gordon-Shapiro), and discounts everything at your WACC (risk-adjusted rate). It's more robust than oversimplified multiples (Revenue × X) or asset-based approaches.

Can I use the result officially?

The result is an estimate, useful for your personal understanding, commercial negotiations, or strategic planning. It's a great starting point.

However, for official or legal use (real estate transaction, business contribution to an SCI, succession, asset impairment tests, significant third-party contracts), we recommend validation by a professional expert: accountant, auditor, or valuation specialist.

An expert can refine assumptions, integrate legal/tax specifics, and provide a signed, defensible report in case of dispute.
