The Role of Capital in Accounting and Business Finance

Updated Mar 2026 5 min read Reviewed by CA

Capital in accounting refers to the financial resources contributed by owners to fund a business, and to the residual ownership interest in the business after liabilities are settled. It appears differently depending on the business structure - as equity share capital in companies, as partner's capital in LLPs and partnerships, and as proprietor's capital in sole proprietorships.

Types of Capital in Business

TypeDefinitionWhere It Appears
Owners' equity / CapitalAmount introduced by owners; residual interest in assets after liabilitiesBalance sheet - equity section
Working capitalCurrent assets minus current liabilities; measures short-term liquidityDerived from balance sheet
Fixed capitalLong-term assets used in the business (land, plant, equipment)Non-current assets on balance sheet
Authorised capitalMaximum share capital a company can issue (stated in MOA)Notes to accounts; not on face of balance sheet
Paid-up capitalCapital actually received from shareholders for issued sharesBalance sheet - equity section
Reserve and surplusRetained earnings + statutory reserves + other reservesBalance sheet - equity section

Capital Account in Different Business Structures

Sole Proprietorship

There is one capital account for the proprietor. All profits increase it; all personal drawings reduce it. At year end: Closing Capital = Opening Capital + Profit − Drawings + Additional Capital Introduced.

Partnership / LLP

Each partner has a separate capital account. Profit allocation, interest on capital, and salary to partners (if stipulated in agreement) are credited; drawings are debited. Fixed capital accounts (capital stays constant) and fluctuating capital accounts (all transactions on one account) are both used.

Private Limited Company

Capital is split into authorised capital (stated in MOA), issued capital (offered to shareholders), subscribed capital (accepted by shareholders), and paid-up capital (actually paid). Retained profits go to reserves and surplus - not directly to the capital account.

Working Capital Management

Working capital = Current Assets − Current Liabilities. It is the single most important indicator of short-term financial health.

ComponentExamplesImpact on Working Capital
Current AssetsCash, debtors, inventory, prepaid expensesIncreases working capital
Current LiabilitiesCreditors, short-term loans, accrued expenses, advance from customersDecreases working capital

Working capital warning signs

  • Negative working capital: current liabilities exceed current assets - immediate liquidity risk
  • Working capital falling consistently over 3 years: deteriorating operational efficiency
  • Debtors turnover slowing: customers taking longer to pay - cash flow stress ahead

Capital Expenditure vs Revenue Expenditure

This distinction determines whether a cost is capitalised (added to a fixed asset and depreciated) or expensed immediately (charged to P&L in the current year).

TypeDefinitionExamplesTreatment
Capital expenditureSpending that creates a long-term asset or enhances its valueBuying machinery, building construction, legal fees for land acquisitionCapitalised; depreciated over useful life
Revenue expenditureSpending for day-to-day operations or to maintain existing assetsRent, salaries, repairs, utilities, stationeryExpensed in current year P&L

Misclassifying capital expenditure as revenue (or vice versa) directly affects your profit, tax liability, and balance sheet. Tax authorities scrutinise this area closely.

Capital Structure and Leverage

Capital structure refers to how a business finances its assets - through equity (owner funds) or debt (borrowed funds). The debt-to-equity ratio measures this balance.

  • High equity, low debt: financially stable; lower return on equity in good times
  • High debt, low equity: higher return on equity in good times; higher risk of default in downturns
  • Optimal capital structure: depends on industry, asset base, and cash flow predictability
  • Banks use D/E ratio in credit decisions - typically prefer D/E ≤ 2:1 for SME lending

QWhat is the difference between capital and revenue reserves?

Capital reserves arise from non-trading activities (share premium, capital profit on revaluation) and cannot be distributed as dividends. Revenue reserves come from operating profits and can be distributed as dividends.

QWhat are drawings and how are they treated?

Drawings are amounts taken out of the business by the owner for personal use. In a sole proprietorship or partnership, they reduce the capital account. In a company, the equivalent would be director remuneration or dividends - drawings as such do not exist in a company.

QDoes increasing authorised capital require RoC approval?

Yes. Increasing authorised share capital requires an EGM, ordinary resolution, amendment to the capital clause of MOA, and filing Form SH-7 with the RoC within 30 days. ROC charges additional fees based on the amount of increase.
