On this page is a Wilshire 5000 Return calculator which gives the dividend reinvested return of the Wilshire between any two arbitrary dates since December of 1970. It can also be used to adjust returns for daily inflation. It uses data from Wilshire Associates, collated by the St. Louis Fed here and here.
The Wilshire 5000 is an index produced by Wilshire Associates which better measures the total United States stock market than other indexes, such as the S&P 500 which represents approximately 80% of the total market cap of public US companies (for comparison, our S&P 500 return calculator). As we went to press, the Wilshire 5000 contains around 3,700 market-weighted components (a little less, to be accurate), covering most of the publicly traded stocks in the United States.
Editor’s Note: The first time you hit ‘Calculate’, wait for the calculator to come back – it takes a few seconds on most computers (it downloads 2 massive, daily data sets) After the first run, calculations will be faster.
The Wilshire 5000 Dividend Reinvested Calculator
Just like our other calculators, we produced this calculator because we are bothered by the returns quoted in various forums when referring to various indexes. A long term investor would have to consciously spend or withdraw dividend money to avoid reinvesting it in some security, so any fair comparison would attempt to factor dividends into security returns.
- Total Wilshire 5000 Return, Dividends Reinvested – The overall non-annualized return you would have made if you invested your money ‘directly’ in the Wilshire 5000 over the dates given and reinvested your dividends
- Annualized Wilshire 5000 Return, Dividends Reinvested – The dividend reinvested Wilshire 5000 return annualized over the dates you gave in the input.
- Total Wilshire 5000 Return – The overall non-annualized return you would have made if you invested your money ‘directly’ in the Wilshire 5000 over the dates given.
- Annualized Wilshire 5000 Return, Dividends Reinvested – The Wilshire 5000 price return annualized over the dates you gave in the input.
- CPI Adjusted? – Once the calculator is finished, this box will reflect whether the above results are adjusted for inflation using CPI.
Methodology on the Wilshire 5000 Return Calculator
The data is from Wilshire Associates, and our calculator downloads new data every night at midnight Eastern Time, ensuring that you’ll always have data up until ‘yesterday’, in most cases. Both index levels are collated at the St. Louis Fed:
Daily inflation numbers we calculate ourselves from monthly levels. See our methodology on this page.
Quite a bit, actually. With both data points scaled to zero for December of 1970 (where the data begins), you can see the return that would have been ignored had we thrown out the dividends:
On the last day of observation (Dec 31, 1970 – Dec 28, 2013 if you want to try it), you’d be looking at 7917.0 vs. 2311.2.
So, yeah, it matters.
