Glen, When I use your calculator, I get Tony's results ($277.17). The following is copied directly from the web page results using initial year "1970", initial amount "50.00", and desired year "2009":
"Current data is only available till 2008. In 2008, $50.00 from 1970 is worth: $277.17 using the Consumer Price Index" What numbers are you using with the calculator? I followed up with a "sanity check" on the numbers to make sure the results are reasonable. The $277 figure corresponds to an average compounded annual inflation rate of 6.3% over 28 years. Your $3300 figure corresponds to an average compounded annual inflation rate of 16.1% over 28 years. $50 * (1+0.063)**28 = $276.63 $50 * (1+0.161)**28 = $3,267.93 Since I don't believe we've averaged 16% annual inflation for the past 28 years, I believe the $277 is closer to the right answer.
