What Is Inflation?
And why your money buys less stuff over time.
3 min read · Updated June 2026
Remember when your grocery bill didn’t make you question every life decision that led you to the checkout line? Or when concert tickets didn’t require a small personal loan?
That’s inflation.
Inflation is simply the gradual increase in prices over time. As prices rise, the same amount of money buys fewer things.
Inflation slowly reduces the buying power of your money over time.
A quick example
Let’s say you have $100. Today, that might buy you 10 pizzas. If inflation causes pizza prices to double over time, that same $100 will only buy five pizzas in the future. Your money didn’t disappear. It just doesn’t go as far as it used to.
That’s inflation in a nutshell.
Why does inflation happen?
There isn’t one single cause.
Sometimes demand for goods (the stuff you buy) and services (the things you pay people to do for you) increases.
Sometimes businesses face higher costs and pass them along to the people that buy their stuff (i.e. us). Sometimes governments make decisions that influence prices.
The important thing to understand is that a little inflation is normal. In fact, most economies expect prices to gradually rise over time.
Why investors care so much about inflation
Because inflation can quietly work against you. Imagine you stick $10,000 under your mattress. Ten years later, it’s still $10,000. Sounds great, right? Not exactly.
If prices have increased a lot during those ten years, that same $10,000 won’t buy nearly as much stuff as it used to.
Inflation doesn’t have to take your money away to make you poorer. It just has to make everything else more expensive.
How people fight inflation
One way is by earning interest on cash.
Simple things like savings accounts, money market accounts, CDs, and even certain bonds can help your money grow instead of sitting idle.
Another approach is investing. Historically, investments like stocks, real estate, and some others have often grown faster than inflation over long periods of time.
That’s one reason many people invest in the first place. They’re trying to grow their money faster than prices are rising.
What about high inflation?
Most of the time, inflation is pretty boring.
Then every once in a while, things get spicy. That’s what happened after the 2020 pandemic when inflation climbed much faster than normal. Suddenly everyone was talking about grocery prices, gas prices, and interest rates.
People who had never used the word “inflation” in their lives suddenly became amateur economists. And honestly, we can’t blame them. When prices jump quickly, it’s hard not to notice.
Is inflation always bad?
Not necessarily.
A small amount of inflation is considered normal and healthy for our economy. The real problems happen when inflation rises too quickly. That’s when people feel squeezed and businesses have trouble planning for the future.
Thankfully, periods of extremely high inflation tend to be the exception, not the rule.
Why it matters
Inflation is one of the biggest reasons people save and invest.
If prices were always the same, you could simply stash cash under your mattress and call it a day. But because prices tend to rise over time, your money needs a chance to grow too.
At Firreo, we think one of the best ways to combat inflation is by building investments that can grow in value and generate income over time.
The goal isn’t just to save money. It’s to make sure your money keeps up with the real world.
