Frequently asked questions
What is purchasing power?
It is how much your money can buy. With 5% inflation a year, $100 sitting idle buys less and less: after 10 years, it is worth about $61 in today's money.
What inflation rate should I use?
Use the average you expect for the coming years. The US Federal Reserve targets 2% a year, but actual inflation can vary a lot from one year to the next.
