If you've ever wondered whether investing in the stock market actually works over the long run — the historical data gives a clear answer. The average stock market returns over the last 50 years show consistent long-term growth despite crashes, recessions, and periods of extreme volatility.
This guide breaks down those average stock market returns decade by decade, explains what the numbers really mean for your investment plan, and shows you how to use historical data to set realistic return expectations.
Quick Answer: What is the average stock market return over the last 50 years? The S&P 500 has delivered an average annual return of approximately 10.5% nominally over the last 50 years (1975–2024). After adjusting for inflation, the real average return is approximately 6.5–7% per year. Despite major crashes in 2000, 2008, and 2020, long-term investors who stayed invested were consistently rewarded.
Why Historical Returns Matter for Investors
Historical stock market returns are the foundation of almost every long-term financial plan. They're used to:
- Set realistic expectations for portfolio growth
- Model retirement savings projections
- Compare investment options against each other
- Decide how aggressively to invest based on time horizon
The key insight from 50 years of data: short-term volatility is normal, long-term growth is consistent. Understanding this distinction is what separates investors who stay the course from those who sell at the worst possible time.
S&P 500 Average Annual Returns: Decade by Decade
The S&P 500 is the most widely followed benchmark for U.S. stock market performance. Here's how it performed each decade over the last 50 years:
| Decade | Average Annual Return (Nominal) | Key Events |
|---|---|---|
| 1975–1984 | ~14.8% | Recovery from 1973–74 bear market, high inflation |
| 1985–1994 | ~14.6% | Bull market, Black Monday crash (1987) |
| 1995–2004 | ~12.1% | Dot-com boom and bust, 9/11, early 2000s recession |
| 2005–2014 | ~7.7% | 2008 financial crisis, slow recovery |
| 2015–2024 | ~13.1% | Long bull market, COVID crash and recovery |
| 50-year average | ~10.5% | Nominal return before inflation |
Even the weakest decade — 2005–2014, which included the worst financial crisis since the Great Depression — still delivered positive average returns.
Nominal vs. Real Returns: What You Actually Earned
The 10.5% figure is a nominal return — it doesn't account for inflation. In real purchasing power terms, your gains were lower.
Average inflation rate over the last 50 years: approximately 3.8% per year (U.S. CPI)
| Return Type | 50-Year Average |
|---|---|
| Nominal return (S&P 500) | ~10.5% |
| Average inflation (CPI) | ~3.8% |
| Real return (after inflation) | ~6.5% |
This means a dollar invested in the S&P 500 in 1975 grew to roughly $117 in nominal terms by 2024. In real (inflation-adjusted) terms, that same dollar's purchasing power grew to approximately $22 — still a remarkable result over 50 years.
For planning purposes: Use 7% as your real return assumption for long-term stock market projections. This is the figure most financial planners rely on, and it conservatively reflects the historical record.
Best and Worst Years in the Last 50 Years
The average tells one story — the year-by-year data tells another. The stock market is anything but smooth.
Best single years (S&P 500):
| Year | Annual Return |
|---|---|
| 1995 | +37.6% |
| 1997 | +33.4% |
| 2013 | +32.4% |
| 2019 | +31.5% |
| 1989 | +31.7% |
Worst single years (S&P 500):
| Year | Annual Return |
|---|---|
| 2008 | −37.0% |
| 2002 | −22.1% |
| 1974 | −25.9% |
| 2001 | −11.9% |
| 2022 | −18.1% |
The swing between best and worst years is enormous — nearly 75 percentage points between 1995 (+37.6%) and 2008 (−37%). This is why time in the market matters far more than timing the market.
What Happens If You Stay Invested Through Crashes
One of the most powerful lessons from 50 years of data is what happens to investors who hold through downturns versus those who sell.
The 2008 financial crisis — a case study:
| Action | Result by 2013 |
|---|---|
| Sold in March 2009 (market bottom) | Locked in ~50% loss |
| Held through the crash | Recovered all losses + gained ~130% |
| Added monthly contributions through crash | Bought shares at discounted prices, higher gains |
The COVID-19 crash (2020):
The S&P 500 dropped 34% in 33 days (February–March 2020) — the fastest crash in history. By the end of 2020, it had returned +18.4% for the year. Investors who sold at the bottom missed one of the fastest recoveries ever recorded.
The pattern repeats across every major crash in the last 50 years: markets recover, and patient investors are rewarded.
$10,000 Invested in 1975: What It Would Be Worth Today
To make the 50-year averages concrete, here's what a lump sum investment would have grown to:
$10,000 invested in the S&P 500 in 1975, with no additional contributions:
| Scenario | Value in 2024 |
|---|---|
| S&P 500 (nominal) | ~$1,170,000 |
| S&P 500 (real, inflation-adjusted) | ~$220,000 |
| High-yield savings at 4% | ~$71,000 |
| Under the mattress (cash) | ~$10,000 (lost ~85% in purchasing power) |
The difference between investing and not investing is staggering over 50 years. Even the inflation-adjusted return of $220,000 on a $10,000 investment represents a 22x increase in real purchasing power.
Average Stock Market Returns With Monthly Contributions
Most people don't invest a lump sum — they invest regularly over time. Here's what consistent monthly investing would have produced historically:
$500/month invested in the S&P 500 from 1975 to 2024 (50 years):
| Amount | |
|---|---|
| Total contributed | $300,000 |
| Estimated final balance | ~$4,200,000+ |
| Estimated gain from returns | ~$3,900,000 |
Over 90% of the final balance came from investment returns — not from the money you put in. This is the compounding effect at work over a full lifetime of investing.
The Formula Behind Long-Term Investment Growth
These results are driven by compound growth — the same principle behind every long-term investment projection. The core formula is:
FV = P × (1 + r)^t
Where FV is the future value, P is your starting amount, r is the annual return rate, and t is the number of years. Each year's growth is calculated on a larger base than the year before — which is why time in the market has such a dramatic effect on the final balance.

International Stock Market Returns: How the U.S. Compares
The U.S. market has been an exceptional performer — but it's not the only benchmark worth knowing.
| Market | Approximate 30-Year Average Annual Return (Nominal) |
|---|---|
| U.S. (S&P 500) | ~10.7% |
| Developed markets (MSCI EAFE) | ~6–7% |
| Emerging markets (MSCI EM) | ~8–9% |
| Global (MSCI World) | ~8–9% |
| U.K. (FTSE 100) | ~6–7% |
The U.S. has outperformed most other markets over the last 30 years. However, diversifying internationally reduces concentration risk — if U.S. growth slows, other markets may outperform.
How to Use Historical Returns in Your Investment Plan
Historical averages are a starting point — not a guarantee. Here's how to use them responsibly:
Use 7% for conservative long-term projections This reflects the real, inflation-adjusted historical average and accounts for fees and periods of underperformance.
Use 10% for nominal projections If you want to see raw growth without adjusting for inflation, 10% reflects the long-term S&P 500 average.
Don't use recent peak returns as your baseline The 2010s were an unusually strong decade (+13% average). Planning based on 13–15% returns leads to underestimating how much you need to save.
Plan for volatility Your portfolio will drop 20–40% at some point. This is normal. Plan your asset allocation and contribution schedule so you can hold through downturns without being forced to sell.
Adjust for your time horizon With 30+ years ahead, a stock-heavy portfolio and 7–10% return assumption is reasonable. With 5 years or less, a lower return assumption and more conservative allocation is appropriate.
Frequently Asked Questions
What is the average stock market return per year?
The S&P 500 has averaged approximately 10.5% per year nominally over the last 50 years. After adjusting for inflation, the real average annual return is approximately 6.5–7%. For planning purposes, most financial advisors use 7% as the long-term real return benchmark.
Is the stock market reliable over the long term?
Based on 50 years of data, yes — the U.S. stock market has delivered positive returns in every 20-year rolling period in its history. Short-term results vary enormously, but long-term investors have consistently been rewarded for staying invested through volatility.
What was the worst decade for stock market returns?
The decade from 2000–2009 — often called the "lost decade" — saw the S&P 500 return approximately −0.95% per year due to the dot-com crash and the 2008 financial crisis. This is the strongest argument for diversification and for not retiring at the start of a bear market.
How does the stock market compare to inflation over 50 years?
The S&P 500's nominal return (~10.5%) has outpaced U.S. inflation (~3.8%) by approximately 6.5–7 percentage points per year over the last 50 years. Stocks have been one of the most effective long-term inflation hedges available to individual investors.
Should I use historical returns to plan my retirement?
Historical returns provide the best available baseline for planning. Use 6–7% as a conservative real return assumption for a diversified portfolio, build in a buffer for sequence-of-returns risk near retirement, and revisit your assumptions every few years as conditions change.
What return should I enter in the investment calculator?
For long-term stock market investing, enter 7% for a conservative real-return estimate or 10% for a nominal projection. For a balanced portfolio (stocks + bonds), use 5–6%. For high-yield savings or CDs, use 4–5% based on current rates.
