Income is money that comes to you regularly, usually from working or from investments. When your parents go to work each day, the money they earn is their income. A teacher's income comes from their salary, a store owner's income comes from selling products, and a writer's income might come from royalties when people buy their books.

Income can come from many sources. Someone might have income from a job, from renting out a house they own, or from money invested in stocks or bonds. A young person's first income might be an allowance for doing chores, or payment for mowing a neighbor's lawn.

The word appears in many important contexts. When adults talk about household income, they mean all the money coming into a family. Annual income means the total earned in one year. Governments collect taxes based on people's income: the more you earn, the more you typically pay.

Understanding income matters because it affects what people can afford and how they plan their lives. A family's income influences where they can live, what activities they can enjoy, and how much they can save for the future. Learning to manage income wisely by spending less than you earn and saving the difference helps people build security and achieve their goals over time.
