Learn › Inflation

In short: Inflation lowers your money's purchasing power: at 2 % cash loses half its value in about 35 years. Real assets like broadly diversified stocks often beat it long term.

Understanding inflation – why money loses value

Inflation means money loses purchasing power. What buys 100 € today costs more tomorrow – cash in the bank is worth less in real terms.

  • Think in purchasing power: even 2 % inflation roughly halves money's value in about 35 years.
  • Keep an emergency fund – but don't leave all your wealth sitting in cash earning nothing.
  • Real assets (broadly diversified stocks/ETFs, possibly property) often beat inflation long term.
  • Plan provision using real, i.e. inflation-adjusted, returns.

What matters

Inflation is the quiet erosion you don't see on your statement: the balance stays the same, but it buys less. At 2 % a year, €10,000 has only about €6,700 of purchasing power left after 20 years. That doesn't mean investing everything – your emergency fund stays safely liquid, even if it loses a little in real terms. But for long-term money, real assets usually protect against inflation better than a savings account.

ExampleAt 2 % inflation, €1,000 has only about €820 of purchasing power in 10 years – without you spending a cent.
Think long term – the FIRE calculator helps put it in context. (Not advice.)

Checklist

  • Keep the emergency fund liquid (despite a real loss)
  • Put long-term money into real assets
  • Calculate with real, inflation-adjusted returns
  • Don't leave all your wealth in cash

Common myths

Myth: My money in the account is safe.

Reality: Nominally yes – in real terms it loses purchasing power at low interest.

Myth: Inflation only affects shop prices.

Reality: It also erodes your savings year after year.

Frequently asked questions

What does inflation mean for my savings?

Cash loses real value when interest is below inflation. Only the emergency fund belongs in cash, not all your wealth.

How do I protect myself from inflation?

With real assets: broadly diversified stocks/ETFs and possibly property usually offset the loss of purchasing power over long periods.
