S&P 500 historical return calculator (1928–2024)

Enter an amount and a start year — see what a lump sum in the S&P 500 would be worth today with dividends reinvested and inflation stripped out. Data goes back to 1928, so you can model the Great Depression, the 1970s stagflation, 2000-dot-com, 2008-GFC, or the 2020 COVID crash.

Uses annual S&P 500 total return (with dividends reinvested) and CPI-U inflation, 1928–2024. Source: Damodaran (NYU Stern) + Shiller CAPE + BLS. Excludes fees, taxes, and bid/ask. Real return = nominal ÷ cumulative CPI.

The S&P 500 total return series (price change plus reinvested dividends) is the single most-cited investment benchmark in the world. But most "historical return" tools drop the dividend piece — inflating the negative message on price alone and understating what shareholders actually earned. This calculator uses total return, then subtracts CPI-U to show real (inflation-adjusted) growth in the initial year's purchasing power.

The compounding math is applied year-by-year to the actual annual return, not to a smoothed average. This matters because sequence-of-returns risk is real — a 1929 investor and a 1935 investor had wildly different first decades even though both eventually recovered. Our year-by-year chart lets you see the drawdowns instead of hiding them in an "annualized" number.

Long-run averages are misleading if you start near a peak or a trough. The 1970s stagflation cost investors most of a decade in real terms. Anyone who bought at year-end 1999 was under water in real terms until 2013. Anyone who bought at year-end 2008 got the fastest bull market in history. Pick your start year and see the actual path — not just the endpoint.

Frequently asked

How far back does S&P 500 data go?

+
The modern S&P 500 index dates to 1957, but back-tested versions using the same methodology exist from 1928 (Standard Statistics 90-stock composite). Damodaran's dataset covers 1928 forward; Shiller's CAPE dataset goes to 1871 using earlier composites. This calculator uses the 1928–2024 window because it's the longest series that includes dividend data cleanly.

Are dividends reinvested?

+
Yes. The return series is "total return" — price change plus dividends reinvested at each year-end. Skipping dividends understates historical S&P 500 performance by ~2 percentage points per year, which compounds to a huge gap over decades. If you invested $10,000 in 1928, price-only would show ~$700K today; total return with dividends shows ~$70M.

What is the average annual return of the S&P 500?

+
Nominal annualized total return from 1928–2024 is approximately 10% (geometric mean, dividends reinvested). Real (CPI-adjusted) is approximately 7%. These are the widely-cited "10% and 7%" figures. Forward-looking models often use 6-7% nominal because current valuations are above long-run averages.

How much would $10,000 invested in the S&P 500 in 1990 be worth today?

+
A $10,000 lump-sum invested in the S&P 500 at the start of 1990, with dividends reinvested and held through end of 2024, would be worth approximately $301,000 nominal ($150,000 in 1990-equivalent purchasing power after CPI inflation). That's a 10.31% annualized nominal return, or 6.71% real return, over the 35-year holding period.

Does this include fees?

+
No. Real-world ETFs (VOO 0.03%, SPY 0.09%, IVV 0.03%) shave the actual return by their expense ratio. Effect over 30 years at 0.09%: about 2.6% of the final balance. Also excludes taxes and bid/ask spread.
