Share capital is the legal or accounting capital represented by issued shares, usually measured at nominal or stated value rather than market value.
Share capital is the legal or accounting capital represented by shares a company has issued. In a nominal-value system, it is generally the aggregate nominal value of those shares, not the shares’ market value, the company’s valuation, or necessarily all cash contributed by shareholders.
For issued share classes with nominal value:
The formula does not apply mechanically to no-par shares. It also does not measure total contributed equity when shareholders paid more than nominal value.
A company issues 500,000 ordinary shares with a $1 nominal value for $6 per share.
| Measure | Calculation | Amount |
|---|---|---|
| Issued shares | Given | 500,000 |
| Nominal share capital | 500,000 x $1 | $500,000 |
| Gross issue proceeds | 500,000 x $6 | $3,000,000 |
| Excess over nominal value | $3,000,000 - $500,000 | $2,500,000 |
The share-capital amount is $500,000. Before issuance costs and subject to the accounting framework, the $2.5 million excess is generally recorded in share premium or additional paid-in capital. Neither amount indicates what the company is worth in the market.
| Measure | What it represents | Typical unit |
|---|---|---|
| Authorized capital | Maximum share or nominal-capital capacity where authorization applies | Shares or currency |
| Issued share capital | Nominal or stated capital attached to issued shares | Currency |
| Subscribed capital | Shares or capital investors agreed to take | Shares or currency |
| Called-up capital | Amount made payable under calls or payment terms | Currency |
| Paid-up capital | Amount paid or validly credited as paid | Currency |
| Uncalled capital | Subscribed amount not yet made payable | Currency |
| Share premium or APIC | Contribution above nominal or stated value | Currency |
These amounts can coincide when every issued share is fully paid at nominal value. They diverge when shares are issued at a premium, partly paid, held in treasury, redeemed, or classified differently for accounting purposes.
GOV.UK company-formation guidance illustrates share capital as the total nominal value of issued shares and expressly distinguishes it from company value. Companies House guidance describes the statement of capital as a snapshot showing issued shares, aggregate nominal value, class rights, and unpaid amounts.
IAS 1 calls for disclosures by class, including shares authorized, issued and fully paid, issued but not fully paid, par value or no-par status, and an opening-to-closing reconciliation of shares outstanding.
A legal instrument called a share is not automatically accounting equity. Redemption obligations, mandatory distributions, or other contractual terms can result in liability or compound-instrument classification under the relevant accounting standard.
Share capital helps readers evaluate:
It is not a standalone measure of solvency, liquidity, profitability, enterprise value, or financial strength.
