Question 1

How does inflation affect the value of money?

Accepted Answer

Inflation raises prices over time, so the same amount buys less in the future. If inflation averages 3% a year, something that costs $100 today costs about $134 in ten years, and $100 saved under a mattress buys roughly $74 worth of goods.

Question 2

How is the future cost calculated?

Accepted Answer

It compounds the amount by the inflation rate for each year: future cost = amount × (1 + rate)^years. Buying power is the reverse: amount ÷ (1 + rate)^years.

Question 3

What inflation rate should I use?

Accepted Answer

Many long-term plans use 2–3%, close to the target of most central banks. For a specific period you can enter the actual average rate you expect or have observed.

Question 4

Why does beating inflation matter for savings?

Accepted Answer

If your savings grow slower than inflation, you lose purchasing power even as the balance rises. That's why money is often invested rather than left in a zero-interest account.
