📖 Deep Dive: Inflation Calculator

How inflation erodes purchasing power

Inflation means the same amount of money buys less over time. The formula: future amount needed = current amount times (1 + inflation rate) to the power of years; conversely, a future amount's purchasing power today = future amount divided by (1 + inflation rate) to the power of years.

A clear example

Assume 3% annual inflation: today's 100000 will require about 180600 in 20 years to buy the same things; conversely, 100000 in 20 years is worth only about 55400 in today's money.

Three takeaways for personal finance

  • Cash has a cost: deposit rates are long below inflation, so idle cash slowly loses value.
  • Raises must beat inflation: a 3% nominal raise with 3% inflation means zero real income growth.
  • Long-term goals need future prices: planning 20-year retirement must use future price levels.
  • Limitations

    Real inflation varies a lot by category (medical and education often rise faster than average, electronics can even fall). This tool uses a single average rate and is for reference only, not investment advice.
