How to Calculate the Value of Company Shares: 5 Methods Explained
When you need to sell a business, bring in investors, complete a merger, settle a legal dispute, or transfer shares between shareholders, one question sits at the centre of every negotiation: what is this company actually worth?
Share valuation is the process of determining a fair value for a company’s equity by analysing its financial performance, assets, and market position. Unlike listed companies where share price is determined by the stock market in real time, privately held companies require a structured methodology to arrive at a defensible number.
This guide explains the five primary methods used to calculate company share value, the formulas behind each, how to choose the right approach, and the specific regulatory and tax context that applies to businesses in Singapore.
What Is Share Valuation and Why Does It Matter?
Share valuation means evaluating the fair value of a company’s equity — either on a per-share basis or as a total equity value that is then divided by the number of shares outstanding. The result is used to inform financial decisions involving that company’s ownership.
Business valuation becomes necessary in a wide range of situations:
- Selling or acquiring a business — buyer and seller need an agreed basis for the transaction price
- Mergers and acquisitions — valuations are required to structure deal terms and assess whether the price paid is fair. Read more on the role of business valuation in mergers and acquisitions
- Raising equity financing — investors need to know what equity stake they are getting for their investment
- Share transfers between shareholders — particularly relevant for private companies with pre-emption rights under the company’s constitution
- Legal disputes and shareholder litigation — courts require independent valuations when disputes arise over fair value. See our guide on business valuation for legal disputes and tax planning in Singapore
- Stamp duty calculations — the Inland Revenue Authority of Singapore (IRAS) charges stamp duty on share transfers at 0.2% of the higher of the consideration paid or the Net Asset Value of the shares
- Employee share option schemes (ESOS) — fair value must be established to price options correctly
- Estate planning and succession — share value forms the basis for inheritance and gift tax considerations
The key challenge for most businesses — particularly startups and SMEs in Singapore — is that shares are not publicly traded. There is no transparent market price. Valuation must therefore be derived through methodology, and the method chosen materially affects the result.
Private vs. Public Company Share Valuation: Key Differences
For publicly listed companies on the Singapore Exchange (SGX), share valuation is straightforward: the share price is the market-determined value, and market capitalisation is simply the share price multiplied by total shares outstanding.
Private companies are fundamentally different:
- No market price exists — shares are not traded on any exchange, so there is no external reference point
- Limited financial disclosure — private companies in Singapore are not required to publish audited accounts publicly unless they exceed the thresholds under the Companies Act 1967 (revenue over SGD 10 million, assets over SGD 10 million, or more than 50 employees)
- Illiquidity discount — shares in private companies are harder to sell; buyers typically demand a discount of 20–30% to compensate for the lack of a ready market
- Control premium — a majority shareholder stake typically commands a premium over a minority stake, even within the same company
- Founder and key person dependency — many private companies have revenue or relationships that are dependent on specific individuals, which affects risk and therefore value
For a comprehensive overview of how these factors shape the valuation process, see our guide on how business valuation is done in Singapore.
The 5 Key Methods to Calculate Company Share Value
There is no single universally correct method. Professional valuers typically apply two or three methods and triangulate the results. The Institute of Valuers and Appraisers Singapore (IVAS), which governs the professional standards for business valuers in Singapore, recognises all five methods below as accepted practice under international valuation standards.
Method 1: Net Asset Value (NAV) — Assets Approach
The NAV method values a company based on the difference between its total assets and total liabilities. It reflects what shareholders would receive if the company were liquidated and all obligations settled.
Formula:
NAV = Total Assets − Total Liabilities
NAV per Share = NAV ÷ Total Shares Outstanding
Worked Example: A Singapore private company has total assets of SGD 8,000,000 and total liabilities of SGD 3,200,000, with 2,000,000 shares outstanding.
NAV = SGD 8,000,000 − SGD 3,200,000 = SGD 4,800,000
NAV per Share = SGD 4,800,000 ÷ 2,000,000 = SGD 2.40 per share
When to use it: The NAV method is most appropriate for capital-intensive businesses (property holding companies, investment companies, manufacturing businesses with significant fixed assets), and for companies in financial distress or undergoing liquidation. It is also the method IRAS uses as a reference point for stamp duty on share transfers.
Limitation: NAV does not reflect a company’s earning power or future potential. A growing technology business with minimal physical assets but strong revenue would be significantly undervalued by NAV alone.
Method 2: Discounted Cash Flow (DCF) — Income Approach
The DCF method values a company by projecting its future free cash flows and discounting them back to their present value using a risk-adjusted discount rate. This is widely regarded as the most theoretically rigorous valuation method because it captures the company’s economic substance — not just what it owns, but what it can generate.
Formula:
Share Value = [Σ (FCFt ÷ (1 + r)^t) + Terminal Value ÷ (1 + r)^n] ÷ Shares Outstanding
Where:
FCFt = Free Cash Flow in year t
r = Weighted Average Cost of Capital (WACC) or required rate of return
t = Year number
n = Final projection year
Terminal Value = FCFn × (1 + g) ÷ (r − g), where g = long-term growth rate
Worked Example (simplified 3-year projection):
A company projects free cash flows of SGD 500,000 (Year 1), SGD 600,000 (Year 2), and SGD 700,000 (Year 3), with a 10% discount rate and a terminal value of SGD 8,000,000 (already discounted).
Year 1 PV = SGD 500,000 ÷ (1.10)^1 = SGD 454,545
Year 2 PV = SGD 600,000 ÷ (1.10)^2 = SGD 495,868
Year 3 PV = SGD 700,000 ÷ (1.10)^3 = SGD 525,921
Terminal Value PV = SGD 8,000,000 ÷ (1.10)^3 = SGD 6,010,518
Total Enterprise Value = SGD 7,486,852
If the company has 2,000,000 shares and SGD 1,000,000 net debt:
Equity Value = SGD 7,486,852 − SGD 1,000,000 = SGD 6,486,852
Value per Share = SGD 6,486,852 ÷ 2,000,000 = SGD 3.24 per share
When to use it: DCF is appropriate for businesses with predictable, growing cash flows — established profitable companies, subscription-based businesses, and long-term service contracts. It is commonly used in business valuation for financial reporting purposes where fair value under SFRS 13 must be supported.
Limitation: DCF is highly sensitive to assumptions. A small change in the discount rate or long-term growth rate can significantly alter the output. It is not suitable for early-stage companies with no track record.
Method 3: Price-to-Earnings (P/E) Ratio — Market Approach
The P/E ratio method values a company by multiplying its earnings by an industry-appropriate earnings multiple. This multiple is derived from comparable listed companies or recent transaction data in the same sector.
Formula:
Share Value = Earnings Per Share (EPS) × P/E Multiple
EPS = Net Profit After Tax ÷ Total Shares Outstanding
Worked Example:
A Singapore food and beverage company generates SGD 1,200,000 in net profit after tax and has 3,000,000 shares outstanding. The industry P/E multiple for comparable listed F&B businesses is 12x.
EPS = SGD 1,200,000 ÷ 3,000,000 = SGD 0.40
Share Value = SGD 0.40 × 12 = SGD 4.80 per share
When to use it: The P/E method is best for businesses in industries with a rich set of comparable listed companies (consumer goods, retail, financial services). It is quick, transparent, and easy for counterparties to understand in a negotiation.
Limitation: P/E multiples can fluctuate significantly with market sentiment. A private company also typically applies a discount of 20–30% to listed-company P/E multiples to account for the illiquidity of its shares.
Method 4: EV/EBITDA Multiple — Enterprise Value Approach
The EV/EBITDA method values a company’s total enterprise value (equity plus net debt) as a multiple of its Earnings Before Interest, Tax, Depreciation and Amortisation. It is widely used in mergers and acquisitions because it is capital-structure neutral — it values the business independently of how it is financed.
Formula:
Enterprise Value (EV) = EBITDA × Industry Multiple
Equity Value = EV − Net Debt
Share Value = Equity Value ÷ Shares Outstanding
EBITDA = Net Profit + Interest + Tax + Depreciation + Amortisation
Net Debt = Total Borrowings − Cash and Cash Equivalents
Worked Example:
A Singapore logistics company has EBITDA of SGD 2,000,000. Comparable transactions in the sector have traded at 6x EBITDA. The company has SGD 3,000,000 in borrowings, SGD 500,000 cash, and 5,000,000 shares outstanding.
EV = SGD 2,000,000 × 6 = SGD 12,000,000
Net Debt = SGD 3,000,000 − SGD 500,000 = SGD 2,500,000
Equity Value = SGD 12,000,000 − SGD 2,500,000 = SGD 9,500,000
Share Value = SGD 9,500,000 ÷ 5,000,000 = SGD 1.90 per share
When to use it: EV/EBITDA is the dominant method in M&A transactions, private equity deals, and business acquisitions. It works well for capital-intensive businesses with significant debt or depreciation charges that distort net profit.
Limitation: EBITDA excludes capital expenditure requirements — a business that needs heavy ongoing investment to sustain its earnings will appear more attractive under EV/EBITDA than it truly is.
Method 5: Comparable Company Analysis (Market Comparables)
This method values a company by benchmarking it against similar companies that have recently been sold or are publicly traded. Valuation multiples (P/E, EV/EBITDA, Price-to-Book, Price-to-Sales) are derived from the comparables and applied to the subject company’s financial metrics, with adjustments for differences in size, growth rate, profitability, and market position.
Formula:
Share Value = (Subject Company Metric) × (Comparable Company Multiple × Adjustment Factor)
When to use it: Comparable company analysis is particularly useful when there is an active market of transactions in the same sector. It provides a market-grounded sanity check on DCF or NAV results, and is commonly used to support business valuations for financial reporting under SFRS 13 Fair Value Measurement.
Limitation: Finding truly comparable companies for a Singapore SME is often difficult. Differences in size, market, and business model require significant adjustments, and the reliability of the result depends on the quality of the comparables chosen.
Which Valuation Method Should You Use?
In practice, professional valuers do not rely on a single method. Comprehensive business valuations in Singapore typically apply two or three methods and present a valuation range. The weight given to each method depends on the purpose of the valuation and the nature of the business.
Business Type | Recommended Primary Method | Secondary Method |
|---|---|---|
Property holding company | NAV | Comparable transactions |
Established profitable SME | DCF or P/E | EV/EBITDA |
Manufacturing or capital-intensive | EV/EBITDA | NAV |
Technology startup | DCF (scenario-based) | Comparable company |
Company undergoing M&A | EV/EBITDA | Comparable transactions |
Insolvent or distressed company | NAV (liquidation basis) | — |
Financial reporting (SFRS 13) | Fair value hierarchy | DCF or market approach |
For businesses navigating a specific transaction — such as a merger, acquisition, or investor round — the method chosen must align with the counterparty’s expectations. Buyers and sellers often have different preferred methods precisely because different methods produce different results.
Share Valuation in Singapore: Regulatory and Tax Context
Singapore has a well-developed framework governing when share valuations are required and what standards apply.
IRAS Stamp Duty
When shares in a Singapore company are transferred between parties, IRAS charges stamp duty of 0.2% on the higher of:
- The actual consideration paid for the shares, or
- The Net Asset Value (NAV) of the shares at the time of transfer
This means that even if shares are sold below NAV (for example, in a distressed or intra-family transfer), stamp duty is calculated on the full NAV. A credible NAV calculation is therefore essential for every share transfer transaction.
ACRA and the Singapore Companies Act 1967
The Accounting and Corporate Regulatory Authority (ACRA) administers the Companies Act 1967, which contains several provisions that directly trigger the need for formal share valuations:
- Section 215 — Compulsory Acquisition: When a bidder has acquired 90% or more of shares in a takeover, remaining shareholders can be compulsorily acquired at “fair value.” Independent valuations are typically required to support the offer price.
- Section 216 — Minority Oppression: Courts hearing minority shareholder disputes can order that shares be bought out at fair value as a remedy. This frequently requires a formal independent valuation.
- Section 210 — Schemes of Arrangement: Court-sanctioned restructuring schemes require that shareholders be adequately informed of the value of their interests.
IVAS Accreditation
Singapore-based valuers who conduct business valuations are governed by the Institute of Valuers and Appraisers Singapore (IVAS), which issues two professional designations:
- CVA (Certified Valuation Analyst): The primary professional qualification for business valuers in Singapore
- AVI (Accredited Valuation Intermediary): A designation for practitioners with business valuation advisory experience
IVAS members operate under the International Valuation Standards (IVS) and Singapore Valuation Standards (SVS), which set minimum requirements for methodology, documentation, and independence. When a share valuation is required for litigation, M&A, or financial reporting purposes, engaging an IVAS-accredited valuer ensures the opinion will withstand professional scrutiny.
Financial Reporting: SFRS 13 Fair Value Measurement
Companies preparing financial statements under Singapore Financial Reporting Standards (SFRS) are required to measure certain assets and liabilities at fair value. SFRS 13, which aligns with IFRS 13, establishes a three-level hierarchy for fair value measurement:
- Level 1: Quoted prices in active markets (applicable to listed shares)
- Level 2: Observable inputs other than quoted prices (comparable transactions, market multiples)
- Level 3: Unobservable inputs (DCF models based on management assumptions)
For private company shares, Level 3 measurements are common and require robust documentation of the assumptions used. See our full guide on SFRS 13 Fair Value Measurement in Singapore.
Common Mistakes in Share Valuation
When Do You Need a Professional Share Valuation in Singapore?
Even experienced business owners make avoidable errors when approaching share valuation. The most common include:
Using a single method in isolation
Each method has limitations. A NAV-only valuation ignores earning power; a DCF-only valuation is only as reliable as its assumptions. Using two or three methods and comparing results produces a more defensible conclusion.
Failing to apply a discount for minority stakes
A 20% shareholding is not worth 20% of the company’s total equity value, because a minority shareholder cannot control decisions, declare dividends, or force a sale. Minority discount rates typically range from 20–40% depending on the rights attached to the shares.
Ignoring the purpose of the valuation
A valuation for IRAS stamp duty purposes follows different conventions from a valuation for an investor round or an M&A transaction. Engaging a valuer without being clear on the purpose can produce a number that is not fit for its intended use.
Relying on outdated financial statements
A valuation based on financial statements that are more than 12 months old may no longer reflect the company’s current condition. Valuers should always work from the most recently completed accounts.
Not considering off-balance-sheet items
Intellectual property, brand value, customer relationships, and key contracts may carry significant economic value that does not appear on the balance sheet. Ignoring them can substantially understate share value.
When Do You Need a Professional Share Valuation in Singapore?
There are many situations in which business valuation is essential — not just transactions. Some of the most common triggers include:
- Pre-IPO preparation — companies considering listing on the SGX require independent valuations to support the offer price
- Private equity or venture capital fundraising — investors require a credible pre-money valuation before they negotiate their equity stake
- Employee share option schemes — the Singapore Income Tax Act requires that ESOS grants be valued at fair market value for tax treatment purposes
- Business succession and estate planning — when shares pass between generations or are transferred under a will, IRAS requires stamp duty to be paid on NAV, and a family dispute about value can only be resolved by an independent opinion
- Joint venture agreements — partners entering or exiting a JV need an agreed methodology for valuing each party’s stake
- Cross-border transactions — Singapore companies involved in transactions with overseas parties may need valuations that comply with both Singapore standards and the standards of the other jurisdiction
All In All
Calculating the value of company shares requires more than picking a formula — it requires selecting the right method for the right purpose, applying it correctly to reliable financial data, and understanding the regulatory context in which the valuation will be used.
For Singapore businesses, share valuation intersects with IRAS stamp duty obligations, Companies Act provisions, SFRS financial reporting requirements, and increasingly with investor due diligence expectations. Getting the number wrong — or using a method that is not appropriate for your situation — can lead to overpayment in a transaction, underpayment of stamp duty, or a valuation that fails to hold up under challenge.

Frequently Asked Questions (FAQ)
The most common approach is to apply two or three valuation methods — typically NAV, DCF, and either P/E or EV/EBITDA — and triangulate the results into a valuation range. The method weighted most heavily will depend on the company’s industry, financial profile, and the purpose of the valuation. For IRAS stamp duty purposes, NAV is the required reference point. For M&A transactions, EV/EBITDA and comparable transactions tend to dominate.
There is no universally superior method. DCF is theoretically the most comprehensive because it captures future earning potential, but it is also the most assumption-dependent. For most Singapore SME transactions, a combination of DCF and EV/EBITDA with a comparable company cross-check produces the most credible and defensible result.
ACRA does not prescribe valuation in routine circumstances, but the Companies Act 1967 triggers formal valuations in specific situations: compulsory acquisition proceedings (Section 215), minority oppression disputes (Section 216), and schemes of arrangement (Section 210). In these cases, the valuation must typically be conducted by an independent IVAS-accredited professional.
Book value (or NAV per share) is derived from the company’s balance sheet — it reflects the accounting value of assets minus liabilities. Market value reflects what a willing buyer would pay in an arm’s-length transaction, which may be significantly higher or lower than book value depending on the company’s growth prospects, brand, and competitive position. For profitable growing companies, market value typically exceeds book value substantially.
For informal or internal purposes, a business owner or accountant may perform their own valuation. However, for any purpose that requires the valuation to withstand external scrutiny — litigation, M&A, financial reporting, regulatory submission, or investor negotiation — engaging an IVAS-accredited valuer is strongly recommended. An accredited opinion carries professional weight that an in-house estimate does not.
For a small to mid-sized Singapore private company with accessible financial records, a straightforward valuation typically takes two to four weeks. Complex valuations involving intangible assets, disputed assumptions, or cross-border considerations may take longer. Engaging a valuer early in a transaction timeline avoids delays at critical stages.
IRAS charges stamp duty of 0.2% on share transfers, calculated on the higher of the actual consideration paid or the NAV of the shares. This means that even if shares are transferred at a price below NAV — as can happen in intra-family transfers or distressed situations — stamp duty is assessed on the full NAV. Accurate NAV calculation is therefore essential before completing any share transfer.
