S&P 500 Average Annual Return: What History Actually Shows
The S&P 500's average annual return is approximately 10.7% (nominal) and 7.5–8% inflation-adjusted since 1957. Individual years range from −38% to +38%, but every 20-year holding period in history has been positive. Here is what that means for your portfolio.

The S&P 500's average annual return is approximately 10.7% (nominal) and 7.5–8% inflation-adjusted since the index was standardised in 1957. Individual years range from −38% (2008) to +38% (1995). Despite this volatility, every rolling 20-year period in S&P 500 history has been positive — a fact that makes the index the benchmark against which all other investments are judged.
S&P 500 historical returns: the actual numbers
The commonly cited "10%" figure is a long-run nominal average. Here is how returns have varied across different time frames:
| Period | Annualised nominal return | Annualised real return (inflation-adjusted) |
|---|---|---|
| Since 1957 (full history) | ~10.7% | ~7.5% |
| Last 30 years (1994–2024) | ~10.7% | ~8.0% |
| Last 20 years (2004–2024) | ~10.3% | ~7.5% |
| Last 10 years (2014–2024) | ~13.1% | ~10.0% |
| "Lost decade" (2000–2009) | −0.9% | −3.4% |
The 2000s are a critical reminder: a decade of flat or negative returns is historically possible. The response to that risk is time horizon and diversification, not trying to time the market in or out.
S&P 500 Average Annual Return by Decade (nominal, including dividends)
*2020s through 2024. Long-run average: ~10.7% nominal per year.
What $10,000 grows to at various time horizons
Using the long-run 10.7% nominal average:
| Years invested | $10,000 grows to | Total gain |
|---|---|---|
| 10 years | $27,600 | +176% |
| 20 years | $76,100 | +661% |
| 30 years | $210,000 | +2,000% |
| 40 years | $579,000 | +5,690% |
The 30-year and 40-year figures illustrate why starting early matters more than investing larger amounts later. A person who invests $10,000 at age 25 has more at 65 from that single investment than a person who invests $40,000 at age 45 — purely because of the additional 20 years of compounding.
The best and worst single years in S&P 500 history
| Year | Return | Context |
|---|---|---|
| 1954 | +52.6% | Post-Korean War recovery |
| 1995 | +37.6% | Early dot-com boom |
| 2013 | +32.4% | Post-financial crisis recovery |
| 2008 | −37.0% | Financial crisis / Lehman collapse |
| 1931 | −43.3% | Great Depression |
| 2022 | −18.1% | Rate hike cycle / inflation shock |
All major drawdowns fully recovered. The 2008 crash (−37%) fully recovered to new all-time highs by 2013. The 2022 decline (−18%) recovered fully in 2023. Every market crash in S&P 500 history has eventually been followed by new highs.
Does the S&P 500 return include dividends?
The "total return" of ~10.7% includes reinvested dividends. The price return alone (excluding dividends) is approximately 7–8%. The S&P 500 dividend yield has averaged around 1.5–2% in recent decades, with higher yields historically when valuations were lower. When you own an ETF like VOO or SPY, dividends are distributed quarterly — most brokerages allow automatic dividend reinvestment (DRIP).
What return should you use for planning?
For long-term financial planning, most evidence-based planners recommend:
- Conservative assumption: 6% nominal / 3–4% real (assumes lower future valuations or lower dividend reinvestment)
- Moderate assumption: 8% nominal / 5% real
- Historical average: 10.7% nominal / 7.5% real
The 10.7% historical average is real but not guaranteed. Using 7–8% nominal for planning provides a margin of error. Planning at 10% and the market delivers 7% is a retirement funding shortfall; planning at 7% and the market delivers 10% produces a pleasant surplus.
Key takeaways
- The S&P 500's long-run average annual return is ~10.7% nominal and ~7.5% inflation-adjusted since 1957.
- Individual years range from −43% to +53% — but every rolling 20-year period in history has been positive.
- The 2000s ("lost decade") returned −0.9% annually — a reminder that any single decade can underperform severely.
- For planning, use 7–8% nominal as a conservative assumption rather than the historical 10.7% peak.
- The total return figure includes reinvested dividends; price return alone is 7–8% historically.
Frequently asked questions
Is 10% per year from the S&P 500 realistic to expect?
The 10.7% nominal average is historically real but not guaranteed. Individual decades can significantly underperform. For planning purposes, most advisers use 7–8% nominal as a conservative long-term assumption to build in a margin of error.
What counts as a "good" annual return?
A return exceeding inflation (currently ~3%) is a positive real return. A return matching the S&P 500 index is "beating" about 80–90% of actively managed funds over 15-year periods according to the SPIVA scorecard.
What was the worst year for the S&P 500?
1931 returned −43.3% during the Great Depression. In modern history, 2008 returned −37%. Both fully recovered — 2008 reached new all-time highs by 2013.
Do S&P 500 returns include dividends?
The total return of ~10.7% includes reinvested dividends. Price return alone (excluding dividends) is approximately 7–8%. When you own an S&P 500 ETF, dividends are distributed quarterly and can be automatically reinvested.
Is it better to invest in the S&P 500 or a total market fund?
The S&P 500 covers 500 large-cap US companies (~80% of US market cap). A total market fund (VTI, FZROX) adds ~3,500 mid-cap and small-cap companies. Historically they have performed within 0.5% of each other annually. Either is an excellent long-term choice.
