Inflation: Why Money Loses Value
Short answer
Inflation is the rise of prices over time. The same goods cost more, which means the same amount of money buys less. Money doesn’t disappear — it loses purchasing power.
A simple example
In 2020 you could buy 20 pounds of rice for $10. In 2025 — only 12 pounds. Same bill, less stuff.
Calculate it yourself
Enter an amount, inflation rate, and time period — see what your money will actually be worth:
| Year | Nominal | Real value | Lost |
|---|---|---|---|
| 1 | $10,000 | $9,259 | −$741 |
| 2 | $10,000 | $8,573 | −$1,427 |
| 3 | $10,000 | $7,938 | −$2,062 |
| 4 | $10,000 | $7,350 | −$2,650 |
| 5 | $10,000 | $6,806 | −$3,194 |
| 6 | $10,000 | $6,302 | −$3,698 |
| 7 | $10,000 | $5,835 | −$4,165 |
| 8 | $10,000 | $5,403 | −$4,597 |
| 9 | $10,000 | $5,002 | −$4,998 |
| 10 | $10,000 | $4,632 | −$5,368 |
In 10 years your $10,000 will be worth the same as today's $4,632. You will lose $5,368 in purchasing power.
Why prices rise
More money — same goods. When governments print money (or ease credit), there’s more money in the economy. The amount of goods hasn’t changed — so prices rise.
Demand exceeds supply. Everyone wants to buy, but production can’t keep up. Sellers raise prices.
Rising costs. Raw materials got more expensive, wages went up, currency exchange rates shifted — businesses pass it on to prices.
Inflation isn’t always bad
Low inflation (2–4% per year) is considered normal. It encourages people to spend and invest rather than hoard cash under the mattress.
The problem is when inflation is high and unpredictable:
| Inflation | What happens |
|---|---|
| 2–4% | Normal. Economy grows |
| 5–10% | Noticeable. Savings lose value |
| 10–20% | Painful. Wages can’t keep up with prices |
| 50%+ | Hyperinflation. Money loses meaning |
How to protect your money
- Don’t keep everything in cash. Money under the pillow is guaranteed to lose value.
- Invest. Stocks, bonds, and real estate have historically outpaced inflation.
- Bank deposits — at minimum. A savings account at least partially offsets inflation.
- Index your income. If your salary doesn’t grow at the rate of inflation — you’re getting poorer every year.
Remember
Inflation is an invisible tax on your savings. Money that just sits there loses a little value every day. The only protection is to make your money work.
