Inflation & purchasing power

Why money buys less over time and what that means for savers and investors.

The quiet tax

Inflation is the general rise in prices over time. At 3% annual inflation, money loses roughly half its purchasing power in 24 years. Cash sitting still isn't standing still — it's drifting backward.

Nominal vs. real returns

A 6% investment return during 3% inflation leaves roughly 3% of real growth — the part that actually buys more stuff. This is why long-term plans must clear the inflation hurdle, and why projections that ignore inflation flatter the future.

What you can do

  • Keep short-term money safe and accessible, even though inflation nibbles it.
  • Give long-term money a chance to outgrow inflation through productive assets.
  • Revisit plans when inflation shifts — fixed assumptions age badly.
  • Focus on what you control: how much you save, for how long, at what cost.
