Historical Stock Market Returns by Decade: Average Annual Returns, Benchmarks & How to Measure Your Portfolio

Why Historical Stock Market Returns Matter for Every Investor

"Stocks return 10% per year." You have probably heard this claim in financial media, from advisors, or in introductory investing books. The statement is rooted in fact—the S&P 500 has delivered approximately 10.0% nominal annualized total return (dividends reinvested) since 1928—but the shorthand obscures enormous variation. Some decades delivered nearly 20% per year; others produced outright losses. Investors who lack context for "normal" returns tend to make poor decisions: they chase unrealistic gains during bull markets and panic-sell during routine corrections. Understanding the full historical record is the first step toward disciplined, evidence-based investing.[1]

The SEC's Investor.gov emphasizes that understanding long-term market patterns helps investors set realistic expectations and avoid costly behavioral mistakes. Since 1926, the S&P 500 has posted positive calendar-year returns roughly 73% of the time. Yet the average intra-year drawdown has been approximately 14%, meaning even in years that ended profitably, investors experienced significant temporary declines along the way. These two facts—consistent long-term gains paired with frequent short-term volatility—form the central tension of equity investing.[3]

The Compound Annual Growth Rate (CAGR) is the most reliable lens for viewing this data because it accounts for compounding and volatility. Unlike simple arithmetic averages—which overstate returns when volatility is present—CAGR tells you the exact annualized rate that would have taken your money from a beginning value to an ending value over a given period. Throughout this article, we use CAGR to present historical returns so you can directly compare asset classes, decades, and your own portfolio on an equal footing.

To measure how your own portfolio stacks up against historical benchmarks, you need just two numbers: what you started with and what you have now. Our CAGR calculator does the rest, converting those inputs into an annualized growth rate you can compare against the benchmarks presented throughout this guide.

S&P 500 Returns by Decade: Nearly a Century of Data (1930s–2020s)

The table below shows the S&P 500 total return CAGR (with dividends reinvested) for each full decade since the 1930s. The variation is striking: the best decade delivered nearly twenty times the annualized return of the worst. No forward-looking forecast can reliably predict which type of decade lies ahead, which is exactly why long-term investors hold through cycles rather than attempting to time them.

1930s: -0.1% CAGR. The Great Depression wiped out nearly 86% of stock values from the 1929 peak to the 1932 trough. While a powerful recovery followed—the S&P 500 roughly tripled from the 1932 low by 1937—a sharp recession in 1937-38 sent stocks tumbling again. The net result was a decade of essentially zero annualized return, a stark reminder that even catastrophic declines can be followed by partial recoveries that still leave investors flat over a full cycle.[2]

1940s: +9.2% CAGR. World War II initially created uncertainty, but the massive industrial mobilization and post-war consumer boom lifted corporate earnings. The GI Bill, suburban housing expansion, and pent-up consumer demand following wartime rationing all fueled equity returns. By the end of the decade, the U.S. economy had transitioned from wartime production to peacetime prosperity.[2]

1950s: +19.4% CAGR. The post-war economic boom, rising middle class, and the dawn of television-era consumer culture made the 1950s the best decade for U.S. stocks in the modern era. Corporate earnings grew at a remarkable pace as new industries—electronics, aviation, petrochemicals—emerged. The Federal Reserve maintained relatively accommodative monetary policy throughout much of the decade.[2]

1960s: +7.8% CAGR. The early 1960s "Go-Go" years saw speculative enthusiasm and the rise of growth stock investing. But the latter half of the decade brought the Vietnam War, rising inflation, and tightening monetary policy. The market peaked in 1966, and while it recovered to new highs by decade's end, the overall CAGR reflected the more muted second half.[2]

1970s: +5.9% CAGR. Oil embargoes, stagflation (simultaneous high inflation and high unemployment), Watergate, and two recessions made the 1970s a challenging decade for equity investors. Headline inflation averaged roughly 7% per year, meaning the real (inflation-adjusted) return was actually negative. Investors who abandoned stocks during this period missed the explosive recovery that followed.[2]

1980s: +17.6% CAGR. Federal Reserve Chairman Paul Volcker's aggressive interest rate hikes in the early 1980s crushed inflation from 13.5% to below 4% by mid-decade. As rates fell from their 1981 peak of nearly 20%, both stocks and bonds rallied powerfully. Deregulation, tax cuts, and the early computing revolution further fueled corporate profits. The decade did include Black Monday (October 19, 1987)—a single-day 22.6% crash—but the market recovered fully within two years.[2]

1990s: +18.2% CAGR. The technology revolution, the rise of the internet, globalization, and a period of fiscal discipline (the U.S. federal budget actually ran surpluses in 1998-2001) produced the second-best decade for U.S. equities. The S&P 500 roughly quadrupled in value. Valuations reached extreme levels by 1999-2000, with the Shiller CAPE ratio peaking above 44—a level that foreshadowed the dot-com crash that opened the next decade.[2, 7]

2000s: -0.9% CAGR. The "lost decade" began with the dot-com crash (2000-2002, a -49% decline) and ended with the Global Financial Crisis (2007-2009, a -57% decline). Two devastating bear markets in a single decade produced the only negative-CAGR decade since the 1930s. Investors who held through both crashes and reinvested dividends still lost purchasing power after accounting for inflation. This decade is a powerful case study in why diversification across asset classes—not just U.S. equities—matters for long-term wealth preservation.[2]

2010s: +13.6% CAGR. The 2010s produced the longest bull market in recorded history, running from the March 2009 low through February 2020. Near-zero interest rates, massive quantitative easing by the Federal Reserve, share buybacks, and the dominance of technology mega-caps (Apple, Microsoft, Amazon, Alphabet, Meta) drove above-average returns. The decade ended with historically elevated valuations, but very few bear-market interruptions.[2]

2020s (through 2025): ~14.5% CAGR. The 2020s have already packed in a COVID-induced crash (-34% in 33 days), the fastest recovery in market history, an inflation spike to 9.1%, the most aggressive Fed rate-hiking cycle in four decades (0% to 5.50%), a -25% bear market in 2022, and a powerful AI-driven rally in 2023-2025 (S&P 500 returned +26.3%, +25.0%, and +17.9% in those three years respectively). With five years left in the decade, the ultimate CAGR remains uncertain—but the volatility so far underscores that even above-average decades are never smooth rides.[8]

Average Annual Returns Across Asset Classes: Stocks, Bonds, REITs, Gold & Cash

Stocks are not the only game in town. A complete picture of historical returns requires comparing equities against bonds, real estate, commodities, and cash. The data below draws primarily from NYU Stern's Aswath Damodaran dataset and the Ibbotson/Morningstar Stocks, Bonds, Bills, and Inflation (SBBI) Yearbook—two of the most widely cited sources in academic and professional finance.[5]

U.S. Large-Cap Stocks (S&P 500): ~10.0% CAGR since 1928. This is the most-cited benchmark in investing. It includes dividends reinvested and reflects the compounded growth of America's largest publicly traded companies. The standard deviation of annual returns has been approximately 19-20%, meaning returns have historically fluctuated widely around this average—ranging from +54% (1933) to -43% (1931) in individual years.[1]

U.S. Small-Cap Stocks: ~11.5% CAGR. Small-company stocks have historically outperformed large caps by roughly 1.5 percentage points per year—the so-called "small-cap premium." However, this premium comes with significantly higher volatility (standard deviation of ~30%) and longer periods of underperformance. Small caps tend to outperform during economic recoveries and lag during late-cycle slowdowns.[5]

International Developed Stocks (MSCI EAFE): ~8% CAGR since 1970. European, Australasian, and Far Eastern developed-market equities have underperformed U.S. stocks over the past several decades, but the gap has not been consistent. International stocks outperformed U.S. equities during the 2000s, for example. FINRA's investing education resources note that geographic diversification can reduce portfolio volatility even when one region lags.[4]

U.S. Aggregate Bonds: ~5.0% CAGR. The Bloomberg U.S. Aggregate Bond Index (formerly Barclays Aggregate) has delivered roughly half the return of stocks with about one-third the volatility. Bonds serve as portfolio ballast during equity downturns—during the 2008 financial crisis, U.S. Treasuries rallied while stocks fell 37%. The 10-Year U.S. Treasury has returned approximately 5.2% annualized since 1928, though the 2022 rate shock produced the worst bond losses in modern history.[5]

REITs (Real Estate Investment Trusts): ~9-10% CAGR since 1972, when the FTSE NAREIT index began tracking. REITs offer equity-like returns with income-oriented cash flows, as they are required to distribute at least 90% of taxable income as dividends. Their correlation with stocks is moderate, making them a useful diversifier. However, REITs suffered disproportionately during the 2008 financial crisis (roughly -37%) due to their real estate exposure.

Gold: ~7-8% nominal CAGR since 1971, when President Nixon ended the dollar's convertibility to gold (Bretton Woods). Gold is often viewed as an inflation hedge and crisis asset, but its returns have been highly volatile and it produces no income (no dividends, no interest). Gold's best decades coincided with high inflation (1970s) and financial crises (2000s, early 2020s).

Cash / Treasury Bills: ~3.3% CAGR since 1928. Cash is the safest asset class in nominal terms but has barely kept pace with inflation over the long run, delivering approximately 0.3-0.5% real return. Every year an investor holds cash instead of a diversified equity portfolio, they sacrifice roughly 6-7 percentage points of expected nominal return—a gap that compounds dramatically over decades.[5]

Bull Markets vs. Bear Markets: Historical Patterns Every Investor Should Know

A bear market is traditionally defined as a 20% or greater decline from a recent peak. According to Hartford Funds' analysis of bear markets since 1928, there have been 27 bear markets in the S&P 500 over that period. The average bear market has lasted approximately 9.6 months with an average decline of -35%. However, bear markets have become less frequent since World War II: between 1928 and 1945 there were 12 (roughly one every 1.5 years), while since 1945 there have been 15 (approximately one every 5.1 years).[6]

Bull markets, by contrast, last far longer and deliver far more. The average bull market has lasted approximately 2.7 years with an average cumulative gain of +112%. The longest bull market in history ran from March 2009 to February 2020—nearly 11 years—and produced a total return of approximately 400%. This asymmetry is the fundamental reason long-term equity investing works: bull markets are both longer and stronger than bear markets, so patient investors who hold through the downturns are rewarded with significant cumulative wealth creation.[6]

Key historical bear markets illustrate the range of severity: the Great Depression (1929-1932) saw an 86% decline over 34 months; the 1973-74 oil crisis produced a 48% decline; Black Monday in 1987 brought a sudden 34% crash; the dot-com bust (2000-2002) eroded 49%; the Global Financial Crisis (2007-2009) inflicted a 57% drawdown; the COVID crash of March 2020 delivered a 34% decline in just 33 days; and the 2022 inflation/rate shock created a 25% bear market. In every single case, the market eventually recovered to new all-time highs.

Recovery times vary considerably. A full recovery—the market returning to its previous peak—has taken an average of 2.5 years. The fastest recovery was in 2020, when the COVID crash bottomed on March 23 and the S&P 500 reached new highs by August. The slowest was after the Great Depression, which took over 25 years to fully recover in real terms. For post-WWII bear markets, recoveries have generally taken 1-4 years. This data is directly relevant to retirement planning: investors nearing retirement need to understand that a poorly timed bear market can delay their goals by several years.[6]

How to Benchmark Your Portfolio Performance Using CAGR

Knowing historical averages is useful, but the real value comes from measuring your own portfolio against them. Here is a step-by-step approach: Step 1 — Gather your beginning and ending portfolio values. Use account statements from your brokerage to find the total value on your start date and the total value today (or on your desired end date). Step 2 — Calculate your personal CAGR using our calculator. Enter your beginning value, ending value, and the number of years. Step 3 — Compare your result to the relevant benchmark. If your portfolio is 100% U.S. equities, compare to the S&P 500; for a balanced portfolio, compare to a 60/40 blend (roughly 8-9% nominal CAGR historically).

As of December 2025, here are the S&P 500 trailing CAGR benchmarks for common comparison periods: 10-year: 14.72%, 20-year: 11.89%, 30-year: 10.32%. The 10-year figure is notably above the century-long average of 10%, boosted by the post-pandemic tech rally and three consecutive years of double-digit gains. The 30-year figure, at 10.32%, sits much closer to the historical mean—illustrating a core principle: the longer the time horizon, the more reliably CAGR converges toward its long-run average.[1]

If your portfolio consistently underperforms its relevant benchmark by 2 or more percentage points per year, the SPIVA Scorecard data suggests the most common culprits are high fees, poor fund selection, or market-timing behavior. A portfolio charging 1% in annual fees starts every year with a 1-percentage-point handicap versus a no-fee benchmark—a drag that compounds into hundreds of thousands of dollars over a 30-year career of saving.[13]

One critical nuance: CAGR measures point-to-point growth and does not account for the timing and size of interim cash flows (contributions and withdrawals). If you have been adding money to your portfolio regularly, your actual experience differs from a simple beginning-to-ending CAGR. For a more precise personal return that accounts for cash flow timing, the Internal Rate of Return (IRR) or Money-Weighted Return (MWR) is the appropriate metric. However, CAGR remains the most useful tool for quick portfolio benchmarking, and our calculator makes the math instant.[14]

Time in the Market vs. Timing the Market: What the Data Shows

One of the most well-documented findings in finance is that investors who try to time the market—jumping in and out based on predictions—consistently underperform those who simply stay invested. J.P. Morgan's Guide to the Markets illustrates this with a striking analysis: an investor who stayed fully invested in the S&P 500 over a 20-year period earned roughly 10.4% annualized. Missing just the 10 best trading days during that period—days that often occur during or immediately after major sell-offs—cut the annualized return approximately in half. Missing the best 30 days reduced the return to roughly 2.1%, barely above inflation.[10]

Charles Schwab's market timing study reinforced this finding with a different methodology. They analyzed five hypothetical investors who each received $2,000 annually over 20 years: a perfect market timer (invested at each year's low), an immediate investor (invested on January 1), a dollar-cost averager (invested monthly), a poor timer (invested at each year's peak), and one who stayed in cash (Treasury bills). The results showed that even the worst timer—who invested at the absolute peak every single year—outperformed the investor who stayed in cash. The gap between perfect timing and immediate investing was relatively small, suggesting that the cost of waiting for the "right moment" almost always exceeds the benefit.[11]

The DALBAR Quantitative Analysis of Investor Behavior (QAIB) 2025 report puts hard numbers on the cost of poor timing. In 2024, the average U.S. equity fund investor earned 16.54%, while the S&P 500 returned 25.02%—an 848-basis-point gap that represents the second-largest investor underperformance of the past decade. Over the 20 years ending December 2024, the average equity investor achieved a 9.24% annualized return versus the S&P 500's 10.35%. While a 1.11 percentage point gap may sound small, over 20 years it means the S&P 500 portfolio is worth roughly 22% more than what the average investor achieved.[12]

Perhaps the most telling statistic from the DALBAR report: investors' "Guess Right Ratio"—the frequency at which they correctly timed inflows or outflows—fell to just 25% in 2024, tying a record low. Withdrawals from equity funds occurred in every quarter of 2024, with the largest outflows happening just before a major return surge. In other words, investors are not just failing to time the market—they are actively making it worse. The data overwhelmingly supports a simple strategy: invest consistently, stay invested, and let compounding work over time.[12]

Setting Realistic Return Expectations for 2026 and Beyond

Past returns do not guarantee future results—but they do provide context for what is statistically likely. Several factors suggest that the next decade may deliver lower returns than the past decade for U.S. equities. The Shiller Cyclically Adjusted Price-to-Earnings (CAPE) ratio stood at approximately 39.8-40.0 as of March 2026. This is only the second time in history the CAPE has surpassed 40—the first was during the dot-com bubble of 1999-2000. Historically, starting CAPE levels above 25 have been associated with below-average returns over the subsequent 10 years, though the relationship is far from a precise timing tool.[7]

Vanguard's Capital Markets Model (VCMM), updated quarterly based on December 31, 2025 data, projects U.S. equities to return 3.3% to 5.3% annualized over the next 10 years—well below the long-run historical average of 10%. The model suggests that the strongest risk-return profiles over the coming decade are in high-quality U.S. fixed income (projected around 4%), U.S. value-oriented equities, and non-U.S. developed markets equities. U.S. growth stocks—which drove much of the 2023-2025 rally—are projected to return just 1.9% to 3.9%.[9]

The current macro environment provides important context. The Federal Reserve held the federal funds rate at 3.50-3.75% at its January 2026 meeting after cutting 175 basis points from the September 2024 peak of 5.25-5.50%. Headline CPI for January 2026 was 2.4% year-over-year, approaching the Fed's 2% target. The 10-year Treasury yield stands at approximately 3.95%. These conditions—moderate but not ultra-low rates, declining but not vanquished inflation—create a different backdrop than the near-zero-rate environment that fueled the 2010s bull market.[15, 16]

None of this means investors should avoid stocks. It means expectations should be calibrated accordingly. If the next decade delivers 4-5% nominal returns for U.S. equities rather than 10-15%, your CAGR-based financial plan should account for that possibility. Diversifying across geographies (international equities may have higher expected returns from lower starting valuations), adding fixed income exposure, and maintaining a higher savings rate can all help bridge the gap between a potential lower-return environment and your long-term financial goals.

Key Takeaways

The S&P 500 has delivered approximately 10.0% nominal CAGR since 1928 with dividends reinvested—but decade-by-decade returns have ranged from -0.9% (2000s) to +19.4% (1950s). No two decades are alike, and extrapolating recent returns into the future is a recipe for disappointment.

Different asset classes offer different risk-return profiles. U.S. large-cap stocks (~10%), small-cap stocks (~11.5%), international stocks (~8%), bonds (~5%), REITs (~9-10%), gold (~7-8%), and cash (~3.3%) have all played different roles in investor portfolios over the past century. Diversification across these asset classes reduces the impact of any single category's bad decade.

Bear markets are painful but temporary. The average bear market lasts 9.6 months with a 35% decline; the average bull market lasts 2.7 years with a 112% gain. Every historical bear market has eventually been followed by a recovery to new all-time highs. The asymmetry between bull and bear markets is the fundamental engine of long-term equity wealth creation.

Market timing consistently destroys value. The DALBAR data shows average investors underperform the S&P 500 by roughly 1 percentage point per year over 20-year periods—a gap entirely attributable to poor timing decisions. Staying invested through volatility, rather than trying to predict market moves, is the single most impactful thing most investors can do to improve their long-term CAGR.

Forward-looking expectations for U.S. equities are below historical averages. With the Shiller CAPE at ~40 and Vanguard projecting 3.3-5.3% annualized returns for U.S. stocks over the next decade, investors should prepare for the possibility of lower returns and consider broader diversification.
