Surplus
**Surplus** means having more than you need — an excess. In everyday use, it’s leftover stock, extra money, or unused capacity. In economics, it usually refers to: - **Consumer surplus** — the gap between what buyers would pay and what they actually pay - **Producer surplus** — the gap between the price sellers receive and the lowest price they’d accept - **Budget surplus** — when revenue exceeds spending If you had a specific sense in mind (economics, business, something else), say which one and I can go deeper.
