Why a 34% Market Drop Hurts More When You're Retired

Most retirement calculators ask for one number: your average yearly return. That single input quietly assumes the order of the years doesn't matter. It does. It might be the most important thing about your retirement that nobody puts on a spreadsheet.

So here is the useful part up front. If you are within five years of retiring, or already retired, your job is not to forecast the market. Your job is to make sure a bad year never forces you to sell shares at low prices, and to decide in advance which account you take money from first. Two levers, both in your hands. Everything below is about how to pull them.

The average return is a story we tell afterward

Take the actual record. From 2016 through 2025, the S&P 500's price return, dividends not included, averaged +13.9% a year and was up in 8 of 10 years. Best year: 2019, at +28.8%. Worst: 2022, at -19.5%.

Nobody who lived through that decade experienced +13.9%. They experienced a sequence, like a playlist shuffled by a toddler. An average is a number computed by someone who never had to live through the order.

Now picture two people who retire with identical portfolios, spend identically, and earn that same average return over 30 years. One gets a year like 2022 first. The other gets a year like 2019 first. Identical averages, different retirements. Not because the market treated them differently, but because the calendar did.

Selling in a hole makes the hole permanent

When you're working, a crash is a sale. Your 401(k) keeps buying and you keep contributing, and the recovery pays you back with interest.

When you're retired, a crash is a bill. Your portfolio is the paycheck. To cover groceries in a down year, you sell shares at low prices. Those shares are gone. They don't come back for the recovery. You sold future growth to buy groceries.

Look at how fast this bites. From Feb 19, 2020 to Mar 23, 2020, the S&P 500 fell 34.1% in 33 days, then returned to its old high 148 days after the bottom. The index healed. A retiree who sold through that stretch did not heal at the same speed, because pieces of the portfolio were already spent. The 2022 drop was the slow kind: 25.4%, 282 days of falling, then 464 days after the bottom before the old high came back. That is a long time to keep selling shares at bad prices.

Here's what compounding looks like when you leave it alone. Start with $1,000,000, add nothing, and grow it at 7% a year for 30 years, before taxes and fees and not adjusted for inflation. You end with about $8.1 million. About $1.0 million of that is money you put in. About $7.1 million is growth. The growth is the entire game, and every panicked sale hands a slice of it to somebody else.

The 4% rule was never a smooth ride

The rule everyone quotes comes from research in the 1990s: William Bengen in 1994, and the Trinity study in 1998. They found that withdrawing 4% of a stock-and-bond portfolio in your first year of retirement, then raising that amount with inflation each year, lasted at least 30 years in most historical periods. Flip it around: save 25 times your yearly spending. Spending $48,000 a year points to a portfolio of about $1.2 million.

Notice what the rule actually tested. Not an average return. Real historical stretches, including the ugly ones, checking whether the money lasted. The whole method is about sequence, which is exactly the part people skip when they quote it. And notice the phrase "most historical periods." Most is not all. The 4% rule is a planning tool with a margin of error, not a promise with your name on it.

Build the buffer, then pick the withdrawal order

Stop forecasting. You can't. Work on what you control.

The buffer. Keep a couple of years of spending in cash or short-term bonds. Not for the return, which is roughly the return on a firm handshake, but for the option it buys you. If the market falls 34.1%, you spend the buffer and touch nothing. When the market recovers, you refill it. You have turned a forced sale into a choice.

The withdrawal order. This is the part people leave to chance, and it is where the money hides. Traditional IRA and 401(k) money has never been taxed. Withdrawals count as income, and before age 59½ you usually owe income tax plus a 10% penalty, with some exceptions. Roth money was already taxed, so qualified withdrawals are tax free. Taxable brokerage money follows its own rules. Which account you tap first changes how much you keep, and it matters most right after a bad market, when your balance is down. Have an accountant run the order for your situation. It is a small cost that can pay off for years.

Do this before the next bad year

Write down your yearly spending, then 25 times that figure, which is your target portfolio by the 4% rule. Then write down how much of your spending sits in cash. If that last figure is nothing, that is your project: move a couple of years of spending into something boring and stable.

Next, write the order. Which account you draw from first, second, and last, and why. Put it somewhere you'll find it in a bad month.

The market will hand you good years and bad ones. You don't get to choose the order. You do get to decide whether a bad year forces your hand.
