What Is Share Capital? Meaning and Types

By Markets & Investing DeskUpdated Nov 10, 2026

Definition

Share capital is the part of a company's equity raised by issuing shares, measured as the number of issued shares multiplied by their nominal (par) value per share.

Key takeaways

Any amount investors paid above nominal value is recorded separately as APIC or share premium.
Paid-in capital equals share capital plus APIC, calculated separately for each share class.
Treasury shares from a buyback stay issued, so share capital does not change when they are repurchased.
Share capital sits in equity with a credit balance and is not an asset or cash on hand.

Share capital is the part of a company’s equity that comes from issuing shares, measured at the shares’ nominal value (also called par value or face value). In the strict accounting and legal meaning, it equals the number of shares issued multiplied by their nominal value per share. Any amount investors paid above that nominal value is recorded separately, as additional paid-in capital (APIC) in US reporting or share premium in UK and Commonwealth reporting.

In everyday use, “share capital” often means all the money a company raised by selling shares, so it is worth checking which meaning a figure refers to.

The legal and accounting meaning. Share capital is the nominal value of all issued shares, common and preferred. A company that issues 500 shares with a nominal value of £1 each has share capital of £500, whatever price those shares actually sold for. Nominal value is a figure fixed in the company’s constitution (the articles of incorporation or charter in the US, the articles of association in the UK). In many jurisdictions it is the minimum price at which the company can issue a share.

Companies usually set nominal value very low. Apple’s common stock, for example, carries a par value of $0.00001 per share. A low par value gives the company flexibility to issue shares at any realistic price and keeps the legal capital figure small. US states also allow no-par stock, in which case the company may record the full proceeds in the common stock account or assign a “stated value” that plays the role of par.

The everyday meaning. Outside accounting, share capital tends to mean the capital received in exchange for ownership in a business, that is, the full amount investors paid. That figure is closer to what accountants call paid-in capital. On a balance sheet, the two never appear as one number.

Companies fund themselves from three broad sources: earnings they retain, money they borrow and money they raise by selling ownership. Share capital belongs to the third. Unlike debt, equity has no maturity date, no fixed payment and no lender-imposed limit. The cost is control: new shareholders gain votes and a claim on future profits, which dilutes existing owners and can lead to disagreements over how the company is run.

Share capital = number of shares issued × nominal (par) value per share
APIC or share premium = number of shares issued × (issue price − nominal value)
Paid-in capital = share capital + APIC

These apply share class by share class. A company with common and preferred stock calculates each separately because each class can carry a different par value.

Authorized share capital is the maximum number (or total nominal value) of shares a company is permitted to issue, set in its constitutional documents. It is a ceiling, not money received. Management often keeps some authorized shares unissued as a reserve for future fundraising, employee stock plans or acquisitions. Raising the limit normally requires shareholder approval. Some jurisdictions, including the UK since the Companies Act 2006, no longer require companies to state an authorized share capital at all.

Issued share capital is the nominal value of shares the company has actually allotted to shareholders. It can never exceed the authorized amount where a limit applies.

Outstanding shares and treasury stock

Outstanding shares are issued shares currently held by investors. Usually issued and outstanding counts match. The main exception is a buyback: when a company repurchases its own shares and holds them as treasury stock, those shares remain issued but are no longer outstanding. This is why share capital is calculated on issued shares, while figures such as earnings per share use outstanding shares.

In UK and Commonwealth practice, shares can be issued with payment due in installments. Called-up share capital is the portion the company has asked shareholders to pay so far. Paid-up share capital is the portion actually received. Shareholders of a limited company are liable only for any unpaid amount on their shares, which is why fully paid shares carry no further liability.

Share capital can also be split by class. Equity (ordinary or common) share capital comes from shares that carry voting rights and a residual claim on profits and assets. Preference (preferred) share capital comes from shares that usually receive a fixed dividend ahead of ordinary shareholders and rank ahead of them in a liquidation, often with limited or no voting rights, depending on the terms of each issue.

Share capital is reported in the equity section of the balance sheet, below liabilities, labeled “shareholders’ equity” or “stockholders’ equity.” A typical US presentation includes:

Preferred stock: par value, shares authorized, shares issued
Common stock: par value, shares authorized, shares issued
Additional paid-in capital
Retained earnings (or accumulated deficit)
Treasury stock, shown as a deduction
Accumulated other comprehensive income

Lines 1 and 2 are share capital in the strict sense. Adding line 3 gives paid-in capital.

No. Share capital is a source of funds, recorded in equity. The cash it brings in is an asset; share capital is the matching claim that owners have on the company. Both sides of the accounting equation (assets = liabilities + equity) rise by the same amount when shares are issued for cash.

Yes. Share capital normally carries a credit balance and increases on the credit side. Under the traditional classification of accounts (personal, real and nominal), it is a personal account, representing amounts owed to shareholders as owners. It is not a nominal account, because nominal accounts hold income and expenses closed out at year end, while share capital is carried forward.

Journal entry for an issue of shares

When a company issues shares for cash above par, the double entry is:

Debit Cash (total proceeds)
Credit Share capital or common stock (shares × par value)
Credit APIC or share premium (the excess)

Issue costs such as underwriting and legal fees are generally deducted from the proceeds recorded in equity (often against APIC or share premium), rather than recognized as an asset.

Initial public offering (IPO). Going public lets a company sell newly created shares to investors on a public market for the first time. One or more investment banks price, market and underwrite the offering, and the proceeds from this primary-market sale go onto the company’s balance sheet. The shares then trade among investors on the secondary market.

Follow-on offerings. A listed company can issue additional shares later. These raise more share capital and APIC but dilute existing holders, so they can be controversial. For a heavily indebted company, issuing stock may be the only practical way to raise funds.

Rights issues and private placements. A company can offer new shares to existing shareholders in proportion to their holdings (a rights issue), or sell shares directly to selected investors. Private companies rely on these routes. In the UK, for example, the Companies Act 2006 prohibits a private company from offering its shares to the general public.

Whatever the route, share capital changes only when the company itself issues or cancels shares, not when investors trade existing shares or the share price moves.

Hypothetical example. Northfield Corp. has 10,000,000 common shares authorized with a par value of $0.01. It issues 2,000,000 shares in an IPO at $15 per share.

Share capital: 2,000,000 × $0.01 = $20,000
APIC: 2,000,000 × ($15.00 − $0.01) = $29,980,000
Paid-in capital: $20,000 + $29,980,000 = $30,000,000

The journal entry debits cash $30,000,000, credits common stock $20,000 and credits APIC $29,980,000, leaving 8,000,000 authorized shares unissued.

A year later, Northfield buys back 100,000 shares and holds them in treasury. Issued shares stay at 2,000,000, so share capital remains $20,000. Outstanding shares fall to 1,900,000, and the cost of the repurchase appears as a deduction from equity on the treasury stock line.

It says little about value. Share capital reflects an arbitrary nominal amount, not what the company is worth, what investors paid or the current share price. Market capitalization (shares outstanding × share price) answers a different question.
It is not cash on hand. The proceeds may have been spent years ago. Share capital records how equity was raised, not what the company holds now.
Terminology varies. “Share capital,” “capital stock,” “common stock,” “paid-in capital” and “paid-up capital” overlap, and different countries’ rules use them differently. Comparing companies requires checking which figure each line contains.
It ignores earnings. Total equity also includes retained earnings or accumulated losses, so a company with large share capital can still have weak or negative equity.

Term	What it measures
Share capital	Nominal value of issued shares
APIC / share premium	Amount received above nominal value
Paid-in capital	Share capital + APIC
Retained earnings	Cumulative profits kept in the business (shown with net income from the income statement)
Total shareholders’ equity	Paid-in capital + retained earnings + other equity items − treasury stock
Market capitalization	Shares outstanding × current share price

FAQs

What does share capital mean for a bank?

The accounting meaning is the same. In banking regulation, common shares and their related surplus form part of a bank's highest-quality regulatory capital, which supervisors require banks to hold relative to their risk-weighted assets.

The Bottom Line

Investors and students reading a balance sheet should treat share capital as a legal and accounting record of how equity was raised. It does not measure what a company is worth or what it holds today. Before comparing companies, check whether a figure shows nominal value only or full paid-in capital, and look at retained earnings and market capitalization for a fuller picture.
