What is capital?
Capital is the money and assets a business uses to build, run, and grow its operations. The term can also refer to a business's net worth, which is the value of its assets minus its liabilities (sometimes called book value).
In practice, capital includes cash on hand, inventory, equipment, property, and any other resources that contribute to generating revenue. For small business owners, capital represents the financial foundation that supports everything from paying suppliers to expanding into new markets.
Capital vs money
While all capital involves money or monetary value, not all money is capital. Money becomes capital when you put it to productive use in your business to generate returns. For example, cash sitting in a personal savings account is money, but cash invested in inventory or equipment that helps your business earn revenue is capital.
Types of capital
Businesses use different types of capital depending on their needs and stage of growth.
- Working capital: the funds available for day-to-day operations, calculated as current assets minus current liabilities.
- Debt capital: money borrowed from lenders such as banks, which must be repaid with interest over time.
- Equity capital: funds raised by selling ownership shares in the business to investors.
- Trading capital: the funds a business uses to buy and sell goods or securities.
- Fixed capital: long-term assets like buildings, machinery, and vehicles that support ongoing operations.
Sources of capital
Businesses can raise capital from internal and external sources, depending on their needs and circumstances.
Internal sources include retained earnings (profits reinvested into the business) and personal funds from the owner. These options keep you in full control but may limit how much you can raise.
External sources offer more options for growth. In the Philippines, small businesses often tap into personal savings, bank loans, SME lending programs, and government grants or support. You might also consider bringing in investors, whether friends and family or angel investors and venture capitalists, or crowdfunding platforms to raise equity capital. Understanding your options is a key part of business finance.
Why capital matters for your business
Capital keeps your business running smoothly. It funds day-to-day operations like paying staff and suppliers, covers unexpected expenses, and lets you invest in new opportunities when they arise. Without adequate capital, even profitable businesses can struggle to meet their obligations.
Working capital is especially important for staying solvent. Keeping enough liquid resources on hand helps you manage cash flow and avoid disruptions that could hurt your operations or reputation.
Example of capital
Consider a small retailer in Manila. Their capital might include the cash in their business bank account, the inventory on their shelves, and the display fixtures and point-of-sale equipment they use to serve customers. If the retailer took out a bank loan to purchase that inventory, the loan represents debt capital, while the owner's initial investment is equity capital. Together, these resources form the financial base that allows the business to operate and grow.
