Purchasing power facts for kids
Purchasing power is a super important idea in economics! It's all about how much stuff you can buy with your money. Think of it like this: if you have $10, how many candy bars can you buy? If each candy bar costs $1, you can buy 10. But if the price goes up to $2, you can only buy 5. Your money can buy less, so your purchasing power has gone down.
This idea helps us understand how much value our money really has. It's not just about how many dollars you have, but what those dollars can actually get you in terms of goods (like food, clothes, or toys) and services (like a haircut or a bus ride).

What is Purchasing Power?
Purchasing power tells us the amount of goods and services that a certain amount of money can buy. For example, if you earn $100, your purchasing power is all the things you can buy with that $100. If prices for things you want to buy go up, your $100 will buy less, and your purchasing power goes down. If prices go down, your $100 will buy more, and your purchasing power goes up.
Adam Smith, a famous economist, explained that purchasing power is about how much "labor" your money can command. This means how many goods or services made by other people you can get with your money.
Why is Purchasing Power Important?
Purchasing power is really important for everyone, from families to governments. Here's why:
- For Families: It affects how much food, clothing, and housing a family can afford. If purchasing power drops, families might struggle to buy the things they need.
- For Businesses: Businesses care because if people have less purchasing power, they might buy fewer products. This can hurt sales and profits.
- For Governments: Governments watch purchasing power to understand the health of the economy. They try to keep it stable so that people can live comfortably and businesses can thrive.
What Affects Purchasing Power?
Several things can change how much your money can buy:
Inflation
The most common reason purchasing power changes is something called inflation. Inflation happens when the prices of goods and services generally go up over time.
- How it works: Imagine a video game that cost $50 last year. This year, because of inflation, it costs $60. If you still have $50, you can no longer buy that game. Your money buys less, so your purchasing power has decreased.
- Why it happens: Inflation can happen for many reasons, like when there's a lot of money in the economy, or when it costs more for businesses to make things.
Deflation
The opposite of inflation is deflation. This is when the prices of goods and services generally go down.
- How it works: If that video game that cost $50 last year now costs $40, your $50 can buy even more than before. Your purchasing power has increased!
- Why it happens: Deflation is less common but can happen if people aren't buying much, or if there's too much supply of goods.
Income and Wages
Your own income also plays a big role in your personal purchasing power.
- More money: If your allowance or your parents' wages increase, you have more money to spend. This means your personal purchasing power goes up, even if prices stay the same.
- Less money: If your income decreases, you have less money to spend, and your personal purchasing power goes down.
Exchange Rates
If you travel to another country, exchange rates affect your purchasing power.
- Strong currency: If your country's money is "strong" compared to another country's money, your money will buy more there. For example, if 1 US dollar can buy 15 Mexican pesos, you can buy more in Mexico with your dollars.
- Weak currency: If your money is "weak," it will buy less in another country.
How is Purchasing Power Measured?
Economists use special tools to measure changes in purchasing power. One common tool is the Consumer Price Index (CPI).
- What it is: The CPI tracks the average prices of a "basket" of common goods and services that people buy, like food, housing, transportation, and healthcare.
- How it helps: By comparing the CPI over time, we can see if prices are going up (inflation) or down (deflation), and how that affects the average person's purchasing power.
Understanding purchasing power helps us make smart choices about our money and understand what's happening in the economy around us!
