See what your money will really be worth in the future — and why cash loses value over time.
Inflation erodes purchasing power over time. This calculator shows two things: what a fixed amount of money will actually buy in the future (its real value in today's purchasing power), and how much you'd need in the future to buy what that amount buys today.
The gap is often startling. At 3% inflation, money loses roughly half its purchasing power over about 24 years — meaning cash sitting idle isn't "safe," it's quietly shrinking.
This is the real reason to invest. Money held as cash loses value to inflation every year. To merely preserve purchasing power, your money has to grow at least at the inflation rate; to build real wealth, it has to beat inflation. That's why long-term savings usually belong in investments that historically outpace inflation, not in a checking account.
Use this to sanity-check long-term goals. If you're saving for something 20 years out, the sticker price today understates what you'll actually need. And money you won't touch for decades almost always belongs somewhere it can outgrow inflation rather than sitting in cash losing ground each year.
