Inflation

This simple gem makes it easy to calculate how much different amounts of money would be worth in certain years. Years from 1800 - 2012 are supported.

Add this line to your application's Gemfile:

gem 'inflation'

And then execute:

$ bundle

Or install it yourself as:

$ gem install inflation

require 'inflation'

# Return the value (rounded to 2 decimal points)
1.from(1800).to(2012)

# Or, if you like more English sounding method chaining...
1.from_1800.to_2012

# Even better, you can use from_now and to_now instead of the year
1.from_now.to_2010
1.from_1898.to_now

# Return true if the year is supported.
1840.year?
=> true

1784.year?
=> false
