A rolling return is the compound annual growth rate for a series of specific time periods. It can be useful when examining returns over specific holding periods. For instance, if you wanted to know the lowest 5 year CAGR for a REIT index you would use a rolling return calculator.
INSTRUCTIONS: The start year and end year inputs are the years between which we shall test and must be between 1972 and 2008. The rolling year is the length of the holding period before moving on to the next year group. For example if testing between years 1990 and 2000, with a 5 year holding period, the year groups would be 1990-95, 1991-96, 1992-97, 1993-98, 1994-99, and 1995-00. Each of these year groups will result in a unique CAGR.
