S&P 500 Rarely Hits 10% Annual Return in Single Years

The S&P 500 almost never delivers its long-term average return in a single calendar year. According to data compiled by NYU Stern professor Aswath Damodaran, only four of the 69 years from 1957 through 2025 saw total returns with dividends reinvested fall between 8% and 12%.

Despite a long-run compound return of approximately 10.6% annually over that period, the typical year deviates significantly from this figure. Of the 69 years analyzed, 15 resulted in losses, while 25 delivered gains exceeding 20%. Only the four years of 1968, 1993, 2004, and 2016 landed within the 8% to 12% band. When the range is widened to 5% to 15%, the count rises to just 14 years, or roughly one in five.

The distribution of returns is skewed by extreme outcomes. The best year in the dataset was 1958, with a return of around 44%, while the worst was 2008, which fell about 37% during the financial crisis. The median annual return for the period was approximately 15%, well above the long-term average. This discrepancy arises because large losses require disproportionately large gains to recover; for instance, the 37% drop in 2008 would have required a gain of nearly 58% just to break even. Such severe downturns pull the compounded long-term return down to the 10.6% level.

Recent history mirrors this volatility. Following an 11.8% return in 2016, the index climbed at least 18% in seven of the next nine years, with declines occurring only in 2018 and 2022. The index also posted gains over 20% for five consecutive years from 1995 to 1999 before dropping in each of the subsequent three years.

Extending the time frame narrows the spread of results, making the long-term average more representative. In rolling five-year periods, only 10 of 65 instances produced annualized returns between 8% and 12%. Over rolling 10-year periods, the range was hit in 13 of 60 cases, or about 22% of the time. For rolling 20-year periods, the frequency increased to 27 of 50 cases, and over rolling 30-year periods, it reached 30 of 40 cases.

Even over longer horizons, results vary by entry point. The worst rolling decade, spanning 1999 through 2008, lost approximately 1.4% annually due to the dot-com crash and financial crisis. However, the worst rolling two-decade stretch, from 1999 through 2018, still returned about 5.6% annually. Every rolling 30-year period in the dataset yielded annualized returns between approximately 9.6% and 13.6%. As of recent reporting, the S&P 500 is up around 14% for 2026 with dividends reinvested, placing it above the central range with about ten weeks remaining in the year.
