Capital in accounting refers to the owner’s financial interest in a business. It represents the residual value of assets after deducting liabilities. In simple terms, capital is what the business owes to its owner. This concept is crucial for all forms of business, whether a sole proprietorship, partnership, or corporation, and it plays a key role in funding operations, expanding business activities, and reflecting overall financial health.
Capital is the value of resources invested in a business by the owner or shareholders. It includes the initial investment and any subsequent profits retained in the business. The fundamental accounting equation that defines capital is:
Capital = Assets – Liabilities
This equation highlights that capital is what remains for the owner after all debts are paid. Capital can increase through profits, additional owner contributions, or revaluation gains. It decreases due to losses, withdrawals, or depreciation in asset value.
