Adjusting stock market return for inflation

The nominal return on investment of $100000000 is $35,459,322,444.85, or 35,459.32%. This means by 2026 you would have $35,559,322,444.85 in your pocket.

However, it's important to take into account the effect of inflation when considering an investment and especially a long-term investment. You can convert S&P returns to their real (inflation-adjusted) value using an inflation calculation based on the U.S. Bureau of Labor Statistics Consumer Price Index (CPI).

In the case of the returns described above, the CPI in 1971 was 40.500 and the CPI in 2026 was 333.952.

The ratio between these CPIs describes how relative buying power of a dollar has changed over 55 years.

Adjusted for inflation, the $35,559,322,444.85 nominal end value of the original $100000000 investment would have a real return of roughly $4,212,453,762.87 in 1971 dollars. This means the inflation-adjusted return is 4,212.45% as opposed to the original 35,459.32%.

Remember, returns are based on the average closing price across the entire month. Some losses are offset by dividend returns.

Dollar-cost averaging

Dollar-cost averaging is an alternative to investing the full lump-sum of $100,000,000.00 up-front. Instead, the capital is invested over a period of time.

Consider a strategy in which $100,000,000.00 was invested in the S&P 500 over a period of no more than 24 months beginning in 1971. This would result in a final amount of $31,191,297,887.77, including dividend reinvestments. In this particular case, dollar-cost average returns are less than the returns of a lump-sum investment (which ends with $35,559,322,444.85).
