Political Calculations Political Calculations is the blogosphere's toolchest! Unlike other blogs dedicated to analyzing current events involving business, investing and economics topics, we create easy-to-use, simple tools to do the math related to them so you can get in on the action too. At present, we've created well over 100 different tools to address topics such as stock market investing, income taxes, the probability of recession, business ownership, personal finance and life in general.
Our most popular tool is The S&P 500 at Your Fingertips, which makes it possible to find the historic rate of return for an investment in the S&P 500, with and without the effects of reinvesting dividends, as well as with and without the effects of inflation, between any months since January 1871.
