What you're referring to is known as equity. In accounting terms, equity represents the ownership value in an asset after all liabilities have been subtracted. It can be calculated using the formula:
\[ \text{Equity} = \text{Assets} - \text{Liabilities} \]
In a business context, equity is often referred to as shareholders' equity, and it represents the net assets attributable to the owners or shareholders of the company. In personal finance, it can refer to the net worth of an individual, which is the difference between their total assets and total liabilities.
