Inflation
Convert buying power between years using a constant annual inflation rate.
Equivalent buying power later
12,800.85
10,000.00 at 2.5% for 10 years
How it works
Future value = amount x (1 + inflation rate) ^ years. Negative years run the same formula backward. The rate is constant. CPI in the real world is a changing basket with revisions.
Use it to sanity-check a cash pile or a long-dated target, not as an official statistics lookup.
Worked example
10,000 today at 3% for 20 years is about 18,061 of future buying power if inflation is actually 3% every year. Your rent, healthcare, and grocery mix will not match that 3%.
Limits
No country CPI series is loaded. Hyperinflation and deflation are just exponents. Personal inflation can be higher than headline when housing dominates.
