A startup valuation estimates how much a business may be worth at a particular time. It can help founders prepare for fundraising, share negotiations, business sales and long-term financial planning.
Unlike established companies, startups may have limited trading history or inconsistent profits. Their valuations therefore depend on assumptions about revenue, growth, profitability, market opportunity and risk.
The Startup Valuation Calculator provides an indicative estimate using:
The result is a general benchmark rather than a formal business valuation or guaranteed investment price.
Annual Revenue (£)
Enter the business’s total revenue for the latest 12-month period.
Annual Growth Rate (%)
Enter the percentage by which revenue increased compared with the previous year.
EBITDA Margin (%)
Enter EBITDA as a percentage of annual revenue.
Valuation Multiple (x)
Enter a multiple supported by comparable businesses, recent transactions or professional research.
Estimate an indicative startup valuation using annual revenue, growth, EBITDA margin, and a chosen valuation multiple. This tool gives a quick benchmark for planning, fundraising discussions, and scenario testing.
Use current or realistic figures. You can choose a revenue-based or EBITDA-based multiple.
Based on a revenue multiple of 4.0x applied to annual revenue.
This startup may be valued at around £2,000,000 using the selected method. Estimated EBITDA is £75,000, and the business shows strong growth with a healthy operating margin.
Annual revenue is the total income generated from sales before business expenses are deducted.
Formula:
Annual revenue = total sales during the year
Founders should use current financial records where possible. Forecast revenue may be used for scenario planning but should not be presented as achieved income.
The annual growth rate measures how quickly revenue has increased.
Formula:
Annual growth rate =
[(Current revenue − previous revenue) ÷ previous revenue] × 100
Strong growth may support a higher valuation, but investors will also consider whether that growth is sustainable and profitable.
EBITDA means earnings before interest, tax, depreciation and amortisation. The EBITDA margin provides an indication of operating profitability.
Formula:
EBITDA margin = EBITDA ÷ revenue × 100
EBITDA is not the same as net profit or cash flow. It does not automatically account for tax, debt repayments, capital expenditure or working-capital requirements.
A valuation multiple is applied to revenue or EBITDA to estimate the business’s value.
Revenue valuation:
Annual revenue × revenue multiple
EBITDA valuation:
EBITDA × EBITDA multiple
Revenue and EBITDA multiples are not interchangeable. The selected multiple should reflect the company’s industry, size, growth, profitability, business model and level of risk.
Three common valuation approaches are used.
This method applies a multiple to annual revenue. It is often used for early-stage or rapidly growing companies that are not yet consistently profitable.
This method applies a multiple to operating earnings. It may be more appropriate for established startups with stable profitability.
A discounted cash flow valuation estimates the present value of expected future cash flows.
This calculator does not perform a complete discounted cash flow calculation because it does not request detailed cash-flow forecasts, a discount rate or a terminal value.
A pre-money valuation is the company’s estimated value before receiving new investment.
A post-money valuation includes the new investment.
Formula:
Post-money valuation = pre-money valuation + investment
For example, a £2 million pre-money valuation plus a £500,000 investment produces a £2.5 million post-money valuation.
Factors that may support a higher valuation include:
Factors that may reduce a valuation include:
Investors will normally assess the overall balance between growth potential and commercial risk.
The calculator can help founders:
Users should test several assumptions instead of relying on one result. Startup valuations are rarely represented accurately by a single fixed number.
The Startup Valuation Calculator is provided for general information and illustrative purposes only. It does not constitute financial, investment, accounting, tax or legal advice.
The result should not be used as the sole basis for fundraising, buying or selling a business, issuing shares, tax reporting or making an investment decision.
Founders and investors should obtain advice from a qualified accountant, financial adviser, solicitor or business valuation specialist before making material financial decisions.
