Surplus refers to something that is extra or more than what is needed. For example, if a farmer grows more crops than he needs, the extra crops are called a surplus. Similarly, if a company produces more goods than it can sell, the excess goods are called surplus. In short, surplus means having more of something than you need or can use. It is often used in economics, trade, and finance to describe a situation where there is an excess of supply over demand or a surplus of funds available for investment.
