Sequence-of-Returns Risk Analyzer

Standard retirement math goes like this: “If your portfolio averages 7% returns and you withdraw 4% per year, your money lasts 30+ years.” The math is correct. The problem: retirement isn't a math equation. It's a sequence of years, in a specific order, with withdrawals happening every year. And the order matters more than the average.

The mechanics. When you withdraw money during a market downturn, you're selling shares at a low price. Those shares are gone — they don't come back when the market recovers. The shares you have left still recover, but you have fewer of them. Each year of bad-returns-plus-withdrawal compounds the damage. Conversely, withdrawals during a bull market are cosmetically painful but mathematically benign — you're still leaving most of the portfolio invested at high prices.

The danger zone. Sequence risk peaks in the 5-10 years around retirement. Before that, you're still contributing — bad returns mean buying shares cheap, which is good. After that, you've survived the opening years and the portfolio has time to recover from shocks. The window in between is where retirement plans actually fail. The 1929, 1973, and 2000 retirees with seemingly identical portfolios had wildly different outcomes purely because of when the bad years hit.

The mitigation toolkit. You can't control market sequences, but you can structure the portfolio to weather bad ones. The classic approaches:

• Bond tent / glide path. Raise bond allocation as you approach retirement, then lower it 5-10 years in. Sacrifices some upside for sequence protection.
• Cash + bond bucket. Hold 2-5 years of expenses in cash and short bonds so you never need to sell stocks during a downturn. Rebalance from stocks when they're up.
• Dynamic withdrawal (guardrails). Cut withdrawals 10% when the portfolio drops below a target, raise them when above. Keeps the success rate high without permanently underspending.
• Delay Social Security to 70. Each year delayed past FRA adds 8% inflation-protected income. Income from SS reduces portfolio withdrawals during the danger zone — the most powerful sequence hedge most retirees overlook.

None of this shows up in the standard calculator. Most tools quote a single “you'll have $X by retirement” number that papers over the entire risk. This tool surfaces it explicitly so you can plan around it.
