Inflation Explained: Why Your Money Is Getting Worse
Inflation isn't just a news headline. It's the silent tax that cuts your purchasing power every year. Larry explains what inflation actually is, how to calculate it, and what to do about it.

In 1994, $100 could fill your grocery cart. Today, that same $100 gets you about $61 worth of the same groceries. Nobody stole from you. Nobody passed a special tax. Inflation just quietly did its thing for 30 years.
This is what nobody explains properly: inflation is the slow death of cash.
What Is Inflation?
Inflation is the rate at which prices increase over time — which is the same as saying it’s the rate at which the value of your money decreases.
When the central bank says “inflation is 3%,” they mean: things that cost $100 last year now cost $103. Your paycheck is worth 3% less in real purchasing power, even if the number is the same.
The US Federal Reserve targets 2% annual inflation as “healthy.” At 2%, prices double roughly every 36 years. At 3%, they double every 24 years.
Larry’s Reality Check
A savings account paying 0.5% interest while inflation runs at 3% is not “saving money.” It’s losing money at 2.5% per year, silently, with a smiley face on the bank’s app. If you have $10,000 in a regular savings account for 10 years at this rate, you’ll have lost roughly $2,200 in real purchasing power. Congratulations on your loss.
The Rule of 72
The Rule of 72 is a quick way to calculate how long it takes for something to double (or halve).
Divide 72 by the annual rate = years to double.
Examples:
- Inflation at 3%: your money’s purchasing power halves in 72 ÷ 3 = 24 years
- Investment returning 7%: your money doubles in 72 ÷ 7 ≈ 10 years
- Savings account at 0.5%: your money doubles in 72 ÷ 0.5 = 144 years (you will be dead)
Why Investing Beats Inflation
The S&P 500 has returned an average of ~10.7% annually (nominal) or ~7.7% after inflation over the long term.
This means:
- Savings account: you lose purchasing power every year
- S&P 500 index fund: you beat inflation by roughly 5-7% per year on average
This is the core mathematical argument for investing. Not that the stock market is great. Just that doing nothing with cash is worse.
What Causes Inflation?
Three main drivers:
- Demand-pull: More money chasing the same goods (like pandemic stimulus + supply chain chaos = 2022 inflation spike)
- Cost-push: Production costs rise (energy, labor), companies pass it to consumers
- Monetary expansion: Central banks print money, more dollars chasing same goods
Understanding causes helps you recognize when high inflation might be temporary versus structural.
How to Protect Against Inflation
In order of effectiveness:
- Index funds / equities: Historically beat inflation by 5-7% annually
- Real estate: Generally keeps pace with inflation long-term
- I-Bonds (US): Government bonds that adjust with CPI — safe but capped
- High-yield savings accounts: Better than 0.5%, but still often below inflation
- Cash under the mattress: Guaranteed inflation loss. Do not do this.
The single most practical thing you can do: invest in low-cost index funds consistently.
Frequently Asked Questions (FAQ)
Is inflation always bad?
Low, stable inflation (around 2%) is considered healthy. It encourages spending and investment rather than hoarding cash, and gives central banks room to cut rates in a recession. The problem is high inflation (5%+) which erodes savings and wages faster than they can be replenished, disproportionately hurting people with fixed incomes and little wealth.
Does gold protect against inflation?
In theory, yes. In practice, barely. Gold has roughly kept pace with inflation over very long periods (decades), but its short-term price is highly volatile and emotionally driven. From 1980 to 2000, gold lost 70% of its value in real terms. The S&P 500 outperforms gold over any 20+ year period in history. Gold is a store of value, not an investment.
What is “real return” vs “nominal return”?
Nominal return is the raw percentage gain. Real return subtracts inflation. If your investment gained 8% and inflation was 3%, your real return is 5%. Always think in real returns when planning for retirement — $1,000,000 in 30 years sounds great until you realize it might only buy what $400,000 buys today.
