Inflation doesn't take your money. It does something worse. It makes your money worth less while leaving the number in your bank account unchanged.

What Is Inflation and Why Should You Care?
Inflation is the rate at which prices for goods and services increase over time. When inflation is 3%, something that costs $100 today will cost $103 next year. That sounds small - but over decades, the effect is devastating.
The Rule of 72 for Inflation
There's a simple shortcut: divide 72 by the inflation rate. The result is the number of years it takes for prices to double.
- At 2% inflation: Prices double in 36 years
- At 3% inflation: Prices double in 24 years
- At 5% inflation: Prices double in 14.4 years
- At 7% inflation: Prices double in 10.3 years
At 3% inflation, the groceries you buy for $200 today will cost $400 in just 24 years.

The Real Rate of Return
The real rate of return is your investment return minus inflation. This is the number that tells you whether your money is growing or shrinking.
Real Return = Nominal Return - Inflation Rate
Examples:
- Savings account at 1%, inflation at 3% → Real return: -2% (you're losing money)
- Government bonds at 4.5%, inflation at 3% → Real return: +1.5%
- Stock index fund at 8%, inflation at 3% → Real return: +5%
If your real return is negative, your wealth is eroding even though your bank balance looks the same.
What Actually Beats Inflation?
Amounts That Typically Beat Inflation
-
Equities (Stock Market) - Average 7-10% nominal returns. After inflation, 4-7% real returns. The most reliable long-term inflation hedge.
-
Real Estate - Property prices tend to rise with inflation (3-5% annually). Combined with rental income, provides strong inflation protection.
-
Inflation-Protected Bonds (TIPS/Linkers) - Designed to keep pace with CPI. Good for capital preservation.
Amounts That Typically Lose to Inflation
- Savings Accounts - In most periods, savings rates are below inflation.
- Cash - Loses purchasing power at the full inflation rate every year.
- Fixed-Rate Bonds (Long-Term) - Vulnerable when inflation rises above the coupon rate.
A Practical Example: $50,000 Over 20 Years
With 3% average inflation:
| Strategy | Value (Year 20) | Purchasing Power (Today's $) |
|---|---|---|
| Cash (0% return) | $50,000 | $27,684 |
| Savings (1.5%) | $67,293 | $37,263 |
| Bonds (4%) | $109,556 | $60,668 |
| Stocks (8%) | $233,048 | $129,074 |
Your $50,000 in cash loses nearly half its purchasing power over 20 years. You need at least a 3% return just to break even.
How to Protect Your Purchasing Power
- Never hold more cash than you need - Keep 3-6 months of expenses as emergency fund. Invest the rest.
- Invest in Amounts that grow faster than inflation - Low-cost global stock index funds are the simplest option.
- Consider inflation-linked investments - TIPS, I-Bonds (US), or Index-Linked Gilts (UK).
- Review annually - Check whether your real returns are positive.
- Use real numbers for planning - $50,000/year in retirement needs will be ~$90,000 in 20 years at 3% inflation.
Frequently Asked Questions
Is 2-3% inflation normal?
Yes. Most central banks target around 2% inflation. This level is considered healthy. The concern is when inflation exceeds this significantly (as in 2022-2023) or turns negative (deflation).
How does inflation affect my salary?
If your salary doesn't increase by at least the inflation rate each year, you're effectively taking a pay cut. A 2% raise with 3% inflation means a 1% real pay decrease.
Should I pay off debt during high inflation?
Counterintuitively, moderate inflation helps borrowers. Fixed-rate debt is effectively reduced in real terms as inflation erodes the value of what you owe.
How do I know if my investments are beating inflation?
Subtract the current inflation rate from your investment returns. If positive, you're growing real wealth. Our SIP Calculator projects investment growth alongside this inflation calculator.
