Autonomous consumption facts for kids
Autonomous consumption is when people spend money on things they need, even if they don't have any income coming in at that moment. Think of it as essential spending that happens no matter how much money you earn.
This type of spending is often for basic needs like food, shelter, or paying off important bills. If someone has no income and still spends, it's called dissaving. This means they are either using up their savings or borrowing money to cover their costs.
Autonomous consumption is different from induced consumption. Induced consumption changes directly with your income – the more you earn, the more you might spend on non-essentials. Autonomous consumption, however, stays fairly constant because it covers things you absolutely need.
Economists use a special idea called the consumption function to show how total spending is made up of both autonomous and induced consumption. It helps explain how households manage their money.

What is Autonomous Spending?
Autonomous spending is the part of your spending that doesn't change when your income changes. It's like a fixed cost you have to pay. This spending is crucial for survival and basic living.
Why Do People Spend Without Income?
People spend without income for several reasons.
- Basic Needs: Everyone needs food, a place to live, and clothes. These are essential expenses.
- Paying Debts: People might have loans or bills that need to be paid regularly.
- Emergencies: Unexpected events can require immediate spending.
When income is zero, this spending comes from other sources. It might come from money saved up over time. Or, people might borrow money from banks or friends.
Autonomous vs. Induced Consumption
It's helpful to understand the difference between these two types of spending.
- Autonomous Consumption: This spending happens regardless of your income. It's the minimum amount you need to spend to live.
- Induced Consumption: This spending changes with your income. If you earn more money, you might spend more on things like entertainment, new gadgets, or vacations. If your income drops, you might cut back on these.
Think of it this way: Autonomous consumption is like the base level of water in a pool. Induced consumption is the extra water you add when you're feeling rich!
How Economists See Spending
Economists use a simple idea to explain total spending. They call it the consumption function. It helps them understand how much people spend in total.
The idea is that total spending (C) is made up of two parts:
- Autonomous spending (c0): This is the essential spending that always happens.
- Induced spending (c1 Yd): This is the spending that changes with your income.
Here, Yd means your disposable income. This is the money you have left after taxes and other payments. The c1 part is called the marginal propensity to consume. It tells us how much more you spend for every extra dollar you earn.
