The Stock Market Averaged WHAT? What Did Your Money Actually Earn?

You have probably heard someone say the stock market has averaged 8%, 10%, or even 12% over the years. But here is a question everyone should ask: What did my money actually earn?

Average returns are useful, but they do not always tell the complete story. There is an important difference between the simple average of annual market returns and the compounded growth of an investment.

That difference becomes especially important when you are approaching retirement and preparing to live on your savings.

Let us examine the mathematics, compare historical Dow Jones Industrial Average and S&P 500 performance, and consider what happens when a retiree needs to withdraw $30,000 every year.

1. How can a positive average return leave you with no profit?

Imagine investing $100,000. During the first year, your investment gains 25%, growing to $125,000. The following year, however, it loses 20%.

You might think a 25% gain followed by a 20% loss leaves you ahead by 5%. But that is not how compounding works.

The simple average annual return is (25% − 20%) ÷ 2 = +2.5%. But the actual compounded annual growth rate is 0%. You started with $100,000 and ended with $100,000. You did not earn a dollar.

Why? Because the 20% loss was calculated on $125,000, not your original $100,000.

• Simple average return: What was the arithmetic average of the annual percentage returns?
• Compounded annual growth rate (CAGR): What constant annual growth rate would produce the same ending value over the investment period?

When you are evaluating how an investment actually grew, the compounded return is especially useful.

2. Historical market performance: 2000–2007

Between 2000 and 2007, investors experienced the bursting of the dot-com bubble, followed by several years of recovery. The results reveal an important difference between average and compounded performance.

These figures represent price changes in the indexes and exclude dividends.

The S&P 500’s simple average annual return was positive, approximately 1.12%, but its compounded annual price return was slightly negative. A hypothetical $100,000 investment tracking the index’s price changes at the beginning of 2000 would have ended 2007 with approximately $99,900.

That is eight calendar years, a positive simple average, and essentially no price growth—and that is before considering inflation.

Investors may also receive dividends. Including reinvested dividends would produce a different, more favorable total-return result. Nevertheless, the mathematical lesson is clear: a positive simple average does not necessarily mean your investment grew at that rate.

3. Historical market performance: 2008–2014

This seven-year period included the global financial crisis and the subsequent market recovery. In 2008 alone, the Dow declined approximately 33.84%, while the S&P 500 price index declined approximately 38.49%.

Again, these are price-only returns, excluding dividends. The Dow’s simple average was approximately 6.1%, yet its compounded growth rate was only about 4.3%. The S&P 500 showed a similar difference.

Why market losses are difficult to recover from

Consider a hypothetical $100,000 investment that loses 33.84%. Its value falls to $66,160. To recover to $100,000, it now needs to grow approximately 51.2%—not 33.84%.

That is because the recovery percentage is calculated on the smaller remaining balance. This is one reason significant market declines can have a lasting effect on compounded returns.

4. Historical market performance: 2015–2021

From 2015 through 2021, both the Dow and S&P 500 experienced substantial overall gains, despite periods of volatility.

The difference between simple and compounded returns was smaller during this period, but it still existed. When returns fluctuate, the arithmetic average will generally exceed the compounded growth rate. The more significant the fluctuations, the greater that difference can become.

Strong average returns are not the same thing as consistent annual returns.

5. What if you invested $100,000 at the beginning of 2000?

Suppose you invested $100,000 at the beginning of 2000 and left it invested through October 30, 2026. During that time, investors experienced the dot-com decline, the 2008 financial crisis, the COVID-19 market decline, inflation, changing interest rates, and multiple strong market recoveries.

*The simple averages include 2026 through October 30 as a partial-year observation. The compounded rates are annualized over the elapsed investment period. Values are rounded.

These figures are based on price-only index performance and do not include dividends, investment expenses, taxes, or inflation.

Both indexes delivered substantial long-term price appreciation, but notice the difference between the simple averages and annualized compounded growth. Those differences matter when estimating future investment balances.

What about dividends?

Dividends are an important part of an investor’s total return. Investors who receive and reinvest dividends can accumulate additional shares, potentially increasing their long-term returns.

Price-only index performance should not be presented as the complete return an investor would have earned. The figures above deliberately exclude dividends so that the historical price-return comparisons use a consistent methodology. They illustrate index price growth, not the complete experience of someone investing through a particular fund or brokerage account.

6. What happens when you retire and need $30,000 every year?

Everything examined so far assumes you invested your money and left it alone. Retirement changes the equation. You have bills to pay, may no longer be contributing to investment accounts, and instead may be withdrawing money from them.

Your bills do not stop coming just because the stock market had a bad year.

A hypothetical $500,000 retirement portfolio

Suppose you retire with $500,000 invested and need to withdraw $30,000 annually to supplement other retirement income. That is $2,500 a month, or an initial withdrawal rate of 6%.

Someone might say that if the market historically averaged 8%, then $500,000 should earn $40,000 and cover the $30,000 withdrawal. The problem is that the stock market does not deliver its historical average every year.

What if your first retirement year looked like 2008?

For simplicity, assume the market loss occurs before the year’s $30,000 withdrawal and apply the Dow’s historical 2008 price decline to this hypothetical portfolio.

After one difficult market year and the withdrawal needed for living expenses, approximately $300,800 remains—a reduction of nearly 40% from the starting balance.

To grow that $300,800 back to $500,000 would require approximately a 66.2% investment gain, assuming no additional withdrawals. But a retiree may still need another $30,000 the next year and the year after that.

This example is hypothetical. It uses the historical 2008 Dow price decline to illustrate the mathematics and is not a simulation of a diversified retirement portfolio. Actual outcomes would depend on asset allocation, dividends, withdrawal timing, fees, taxes, and other factors.

7. Understanding sequence-of-returns risk

Sequence-of-returns risk refers to the effect the timing and order of investment gains and losses can have on a portfolio, particularly when money is being withdrawn.

Two investors could experience the same annual returns in a different order. If neither contributes or withdraws money, both can finish with the same ending balance. But when withdrawals enter the equation, their results can differ.

A simple example

Imagine two retirees, each starting with $500,000 and withdrawing $30,000 at the end of each year. Both experience a 20% gain and a 20% loss, but in a different order.

Both retirees experienced the same two annual returns, had a simple average annual return of zero, and withdrew $60,000. Yet Retiree A finished with $12,000 less because the market loss arrived before the recovery while money was also being withdrawn.

8. What should you consider before retirement?

Does this mean you should not invest in the stock market? Absolutely not. Historically, stock-market investing has offered opportunities for substantial long-term wealth creation. But there is a difference between accumulating retirement savings and depending on those savings for income.

• How much income will you need? Identify essential expenses and discretionary spending, then determine how much must come from the portfolio.
• How will you handle market downturns? Consider how a significant decline early in retirement could affect withdrawals.
• Do you have sufficient liquidity? Cash reserves or other accessible assets may reduce the need to sell investments during unfavorable conditions, although cash has inflation and opportunity costs.
• Is your portfolio appropriately diversified? Diversification does not eliminate the possibility of losses.
• How will inflation affect withdrawals? A fixed withdrawal buys less over time if living costs rise.
• Have you considered taxes, fees, and expenses? These can reduce the amount available for spending.
• Do you understand available income strategies? Approaches can involve different levels of flexibility, market exposure, guarantees, costs, and restrictions.

No single strategy is appropriate for everyone. The goal is to understand the options and how they fit individual circumstances.

9. The bigger picture: What can your money do for you?

The purpose of this discussion is not to discourage anyone from investing. It is to encourage better questions.

The next time someone tells you the market averaged 10%, ask whether that is the simple average or the compounded annual return. Ask whether it includes reinvested dividends or only price changes. If you are preparing for retirement, ask how withdrawing money during a market decline could affect your savings.

Once you retire, the conversation changes. It is no longer only about accumulating money. It is about understanding how that money can help support your lifestyle throughout retirement.

At Beyond the Credit Score, we believe financial education should help people understand the information before making important decisions. We are not here to tell you what financial decisions to make. We are here to help you ask better questions and understand your options.

It is not just about what your money averaged. It is about what your money actually earned—and what that money can do for you.
