Common pitfalls

  • Fees, penalties, inflation, and local rules can make real outcomes differ from simple formulas.
  • Treat results as guidance, not financial, tax, legal, or investment advice.

Frequently asked questions

How does it compute inflation-adjusted value?

It compounds an annual inflation rate over the number of years to show how purchasing power changes between two points in time.

What is the difference between nominal and real value?

Nominal is the face amount, while real value adjusts for inflation to reflect what the money can actually buy.

Does it use official CPI data?

It uses the inflation rate you supply, so results are only as accurate as that assumption. For precise history, plug in published CPI figures.

Why does a small rate compound to a big difference?

Inflation compounds, so even 3% a year roughly halves purchasing power in about 24 years.

Can I work backward to today's equivalent?

Yes. Enter a past amount and the rate to estimate its equivalent in today's money.

Is any data uploaded?

No. All calculations run locally in your browser.
