The following assumptions were used and are for illustration only:
  • You are assumed to be vested in both the traditional benefit (5 years of credited service) and the new sustainable income benefit (3 years of service) when you retire (if not already). You must be vested to receive retirement benefits.
  • We have estimated your contribution rate to be $2.50 and it will grow by $0.25 per year for 5 years under the rehabilitation plan.
  • To the extent the actual rate contributed is different, your benefit at retirement will be different. Actual benefits will depend on actual hours worked, actual hourly contribution rate, and actual plan investment returns.
Investment return assumptions: The tool includes historical returns from 1927 through 2015. If the projection to age 85 extends beyond the 2015 historical data, the tool uses an assumed 6% rate of return. For example, if you enter 1990 for the starting year but your projection goes out 50 years, the tool will assume historical returns for the first 25 years and 6% for the second 25 years.

Investment mix assumptions: We assumed the funds are invested in a 50% stock / 50% bond mix, using:
  • Stocks – the S+P 500 Index, and
  • Bonds – from 1955 to 1979 a mix of 40% 3-Month Treasury Bills and 60% 10-Year Treasury Bonds, and from 1980 to 2015 the Barclays Aggregate Bond Index.

Helpful Hints:
  • The modeling tool works best with Google Chrome or Windows Internet Explorer.
  • To reset the modeling tool to its original settings, refresh the browser by pressing the F5 key (Chrome) or Ctrl F5 (Internet Explorer).
