Why it matters
At 3% inflation, money loses about a quarter of its value over a decade. Planning for a long-term goal means aiming past the sticker price of today — a reason to invest rather than hold cash.
Frequently asked questions
How does inflation reduce purchasing power?
Prices rise by the inflation rate each year, so a fixed sum buys less. Its real value is amount ÷ (1 + rate)^years. At 3% for 10 years, $1,000 is worth about $744 in today's money.
What does the other mode show?
The amount you would need in the future to preserve today's purchasing power: amount × (1 + rate)^years. At 3% for 10 years, you would need about $1,344 to match $1,000 today.
Is the rate compounded?
Yes, annually. Each year's inflation applies to the previous year's value, exactly like compound interest running against you.
