Average Stock Market Return: Historical Data & What to Expect
⚡ Key Takeaways
- The S&P 500 has returned approximately 10% per year on average since 1926, or about 7% after inflation
- Nominal returns do not account for inflation; real returns reflect actual purchasing power growth
- Individual years vary wildly — the market has returned as much as +54% and as little as -43% in a single year
- Long-term averages smooth out short-term chaos, which is why time in the market matters more than timing the market
- Reinvesting dividends accounts for roughly 40% of total long-term returns
The Average Stock Market Return
The average stock market return is approximately 10% per year based on the S&P 500's performance from 1926 through 2025. This is the figure most commonly cited when discussing long-term equity returns, and it includes both price appreciation and reinvested dividends.
That 10% is a nominal return — it does not account for inflation. After adjusting for the historical average inflation rate of roughly 3%, the real return drops to approximately 7% per year. This 7% figure represents actual purchasing power growth and is the more meaningful number for long-term financial planning.
These averages are powerful. A $10,000 investment growing at 10% nominally becomes $174,000 over 30 years. At the inflation-adjusted 7%, it becomes $76,000 in today's purchasing power. Either way, the stock market has been the single most effective wealth-building vehicle available to ordinary investors.
Nominal vs Real Returns
The distinction between nominal and real returns is critical for financial planning.
Real Return ≈ Nominal Return - Inflation Rate| Period | Nominal Return (S&P 500) | Inflation | Real Return |
|---|---|---|---|
| 1926-2025 | ~10.0% | ~3.0% | ~7.0% |
| 1950-2025 | ~11.1% | ~3.5% | ~7.6% |
| 2000-2025 | ~9.5% | ~2.7% | ~6.8% |
| 2010-2025 | ~13.5% | ~2.9% | ~10.6% |
The 2010-2025 period was exceptional — driven by tech sector dominance from stocks like AAPL, MSFT, NVDA, AMZN, and GOOGL. Expecting 13%+ returns going forward would be unreasonably optimistic. The long-term 10% nominal / 7% real figures are more reliable for planning.
When projecting future portfolio values, always use real returns. Telling yourself "I will have $1 million at retirement" means little if inflation has eroded its value to the equivalent of $500,000 in today's dollars. Real returns keep your projections honest.
Pro Tip
Why Individual Years Vary So Much
The "average" of 10% is deeply misleading if you expect it to show up each year. The stock market rarely returns anything close to 10% in any given year.
Distribution of annual S&P 500 returns (1926-2025):
| Return Range | % of Years | What It Feels Like |
|---|---|---|
| Below -20% | ~6% | Panic, capitulation |
| -20% to -10% | ~8% | Fear, portfolio anxiety |
| -10% to 0% | ~12% | Mild discomfort |
| 0% to +10% | ~17% | Mediocre, impatient |
| +10% to +20% | ~24% | Satisfied |
| +20% to +30% | ~19% | Euphoric |
| Above +30% | ~14% | Irrationally exuberant |
The market delivers returns between 0% and +20% only about 41% of the time. In the other 59% of years, returns are either negative or above +20%. The "average" emerges only over long holding periods as strong years more than offset weak ones.
This volatility is the price of admission. The reason stocks return more than bonds or savings accounts is precisely because investors must tolerate gut-wrenching drops. The compound interest page shows how staying invested through volatility is what produces those long-term averages.
The Role of Dividends in Total Returns
A significant portion of the stock market's historical return comes from dividends, not just price appreciation.
From 1926 to 2025, dividends contributed roughly 40% of the S&P 500's total return. In earlier decades, when dividend yields were higher (4-5%), the contribution was even greater. Today, the S&P 500 yields approximately 1.3-1.5%, with more of the total return coming from price appreciation.
Total Return = Price Return + Dividend Return| Investment of $10,000 in S&P 500 | Price Only (No Dividends) | With Dividends Reinvested |
|---|---|---|
| After 10 years | ~$21,000 | ~$26,000 |
| After 20 years | ~$44,000 | ~$67,000 |
| After 30 years | ~$92,000 | ~$174,000 |
Reinvesting dividends through index funds that automatically reinvest is one of the easiest ways to capture the full market return. Every dividend reinvested buys more shares, which earn more dividends, which buy more shares — the compounding flywheel in action.
How Different Asset Classes Compare
The stock market's ~10% average return looks even more impressive when compared to alternatives.
| Asset Class | Historical Avg Annual Return | Risk Level |
|---|---|---|
| U.S. Large-Cap Stocks (S&P 500) | ~10% | High |
| U.S. Small-Cap Stocks | ~12% | Higher |
| International Developed Stocks | ~8% | High |
| U.S. Bonds (Aggregate) | ~5% | Low-Moderate |
| Treasury Bills (Cash) | ~3.3% | Very Low |
| Inflation | ~3% | — |
| Gold | ~5.5% | Moderate |
Stocks have outperformed every other major asset class over multi-decade periods. The gap is even wider after adjusting for inflation — cash and many bond strategies barely keep pace with inflation, meaning they preserve purchasing power but do not build real wealth.
This does not mean you should invest 100% in stocks. Bonds reduce portfolio volatility and provide rebalancing opportunities during downturns. But for any money you will not need for 10+ years, stocks have been the most reliable path to real wealth accumulation.
Time in the Market: What the Data Shows
The probability of positive returns increases dramatically with holding period.
| Holding Period | % of Periods with Positive Returns (S&P 500) |
|---|---|
| 1 day | ~53% |
| 1 year | ~73% |
| 5 years | ~88% |
| 10 years | ~94% |
| 15 years | ~100% |
| 20 years | ~100% |
There has never been a 15-year period where the S&P 500 delivered negative total returns (with dividends reinvested). The worst 20-year annualized return was still positive at roughly 6% nominal.
This is why dollar-cost averaging — investing a fixed amount monthly regardless of market conditions — works so well. You do not need to predict which years will be good. You just need to stay invested long enough for the averages to assert themselves.
Frequently Asked Questions
Does the 10% average include dividends?
Yes. The ~10% average annual return for the S&P 500 includes both price appreciation and reinvested dividends. Without dividends, the price-only return is closer to 7-8%. This is why dividend reinvestment is critical — skipping it means forfeiting roughly 2-3 percentage points of annual return, which compounds into massive differences over decades.
Should I expect 10% returns going forward?
No one can predict future returns with certainty. Many financial analysts project slightly lower returns (7-9% nominal) for the coming decade due to elevated stock valuations and interest rate dynamics. However, similar predictions have been made before and the market has often surprised to the upside. Use 7% real (inflation-adjusted) returns for conservative planning and treat anything above that as a bonus.
How does the average return apply to my specific investments?
The 10% figure is a broad market average for the S&P 500. Your individual portfolio may return more or less depending on what you own. A tech-heavy portfolio (QQQ, NVDA, AAPL) may outperform in some periods and underperform in others. A diversified portfolio tracking the total market (VTI) will closely mirror the overall average. The further your portfolio deviates from the broad market, the more your returns will differ from the historical average — in either direction.
