Retirement timing matters more than most people realize. Retire in 1982, and you surf the greatest bull market in history. Retire in 1929 or 2008, and you face a financial disaster. The difference isn't luck. It's sequence of returns risk.
Free retirement calculators assume smooth returns. They'll tell you "7% average return means you can spend $50,000 per year." But averages lie. A 60/40 portfolio that averages 7% can deliver anywhere from -30% to +40% in any single year. If you get the bad years early in retirement, your plan fails. If you get them late, you're fine.
This is why historical backtesting matters. Instead of guessing, you can test your plan against every historical retirement year from 1928 to today and see what actually happened.
The only way to know if your retirement plan survives a crash is to test it against real crashes. Run your numbers against 1929, 1973, 2000, and 2008. Test your plan now →
Why Retirement Timing Matters
During your working life, market crashes are good for you. You're buying shares at lower prices. A 30% crash means you buy 30% more units with the same dollar amount. You want volatility when you're accumulating.
In retirement, it's reversed. You're selling units to fund your lifestyle. A 30% crash forces you to sell 43% more units to get the same dollar amount. Lock in those losses, and you have fewer units left to benefit from the recovery.
This is sequence of returns risk. Two retirees with identical portfolios and identical average returns can have completely different outcomes based solely on the order those returns arrive.
Example: Retiree A gets +20%, -10%, +15% in years 1-3. Retiree B gets -10%, +15%, +20%. Same average return (8.3%), but Retiree B's portfolio is worth 12% less after 3 years because they sold into the crash in year 1.
The 5 Worst Years to Retire
Based on historical data from 1928 to 2025, these are the retirement years that caused the most damage. The numbers below are real data, not projections.
1973 — Stagflation & Oil Crisis (Worst)
What happened: The 1973 retiree faced falling markets and soaring inflation simultaneously. Markets dropped 14.8% in 1973, then another 26.5% in 1974. Meanwhile, inflation hit 16%, destroying purchasing power.
Why it was worse than 1929: At least 1929 had deflation, which meant your cash went further. The 1973 retiree faced the double whammy: portfolio value falling while living costs soared. A 60/40 portfolio lost about 38% in real (inflation-adjusted) terms over two years while you were withdrawing for living expenses.
Could you survive it? Yes, if you kept withdrawals conservative. Using our calculator's historical data, a $1M portfolio in 1973 with 5% initial withdrawals ($50K/year, inflation-adjusted) survives the full 30 years. At 6%, you run low but survive. At 7%, you fail around year 22.
Lesson: Inflation combined with market crashes is the absolute worst case. Free calculators that ignore inflation or use nominal returns won't show you this risk. Historical backtesting shows real (inflation-adjusted) outcomes.
Will YOUR plan survive a 1973-style crash? Most people don't know. Free calculators show average returns, not worst-case scenarios. Test your exact plan against 98 years of real market data (including crashes) with our Advanced calculator. See if you'd survive →
1969 — Start of the Stagflation Era
What happened: You retire in 1969 thinking you've timed it well. Markets had been strong through the 1960s. Then you immediately hit -8.6% returns. Markets partially recover in 1970-1972, but inflation is eating your purchasing power. Then 1973-1974 hits and your portfolio gets crushed.
The insidious nature: Your portfolio balance might look OK in nominal terms. But with 6-9% inflation every year, you need higher withdrawals just to maintain your lifestyle. By the time you reach 1974, you've been drawing down a portfolio that's growing slower than inflation for 5 years, then you hit the worst two-year stretch (1973-1974) with an already depleted portfolio.
Could you survive it? Yes, but it's tight. The 1969 start year is one of the worst in the rolling period analysis. A 5% withdrawal rate survives. A 6% rate is borderline. Anything above 6% and you're in serious trouble by the mid-1980s.
Lesson: Sometimes the worst retirement year isn't the year of the crash—it's a few years before, when you've already depleted your portfolio before the crash arrives.
1929 — The Great Depression
What happened: The 1929 retiree watched their portfolio collapse. Down 8.3% in 1929, down 25% in 1930, down 44% in 1931, down another 9% in 1932. By the end of 1932, a $1 million portfolio was worth about $170,000 — and you'd been withdrawing $50,000 per year to live. Do the math. Most 1929 retirees went broke.
The silver lining: Deflation meant your cash went further. While your portfolio was collapsing, living costs dropped by about 30% from 1929 to 1933. If you could cut spending in line with deflation and avoid panic-selling, you could survive.
Could you survive it? Barely. A 5% withdrawal rate ($50K from $1M, adjusted for deflation) survives 30 years. A 6% rate fails around year 24. Anything above 6% and you're broke before the recovery arrives.
Lesson: Even the Great Depression was survivable with conservative withdrawal rates. But you need to know your worst-case safe income before you retire—not discover it after.
2000 — The Dot-Com Crash
What happened: Three straight years of losses at the start of retirement. A 60/40 portfolio lost about 20% over three years while you were withdrawing. Then the recovery was interrupted by the 2008 GFC just as you were getting back on track.
The 2000 retiree's unique pain: You survive 2000-2002. Markets recover. By 2007, you're thinking you made it. Then 2008 hits and you're down 38% in a single year. Two major crashes in your first 9 years of retirement.
Could you survive it? Yes, more easily than 1929 or 1973. Inflation stayed low (2-4%), so your purchasing power wasn't destroyed. A 5% withdrawal rate survives comfortably. Even a 6% rate makes it through. The 2000 start year is bad, but not catastrophic.
Lesson: A diversified 60/40 portfolio with conservative withdrawals can survive even multiple crashes in a single retirement. The key is not panic-selling and not over-withdrawing early.
2008 — The Global Financial Crisis
What happened: The worst single-year crash since 1931. Australian shares dropped 40% in a single year. If you retired in early 2008 with $1 million, you watched it become $600,000 by March 2009 while withdrawing $50,000 to live. By the end of 2009, you had about $680,000 left.
The good news: The recovery was fast. By 2013, markets were back to 2008 levels. By 2020, well above. Low inflation (2-4%) meant your real purchasing power held up. The 2008 retiree faced a brutal first year but recovered.
Could you survive it? Yes, comfortably if your withdrawal rate was 5% or below. Even at 6%, you survive the full 30 years. The 2008 start year is one of the more survivable "bad" years because the recovery was strong and sustained.
Lesson: A single bad year—even -40%—is survivable if you don't panic-sell and if the recovery follows. What kills you is prolonged negative returns (1929-1932, 1973-1974) combined with high inflation.

What Free Calculators Don't Show You
MoneySmart, industry fund calculators, and basic online tools can't show you sequence of returns risk. Here's why:
| Feature | Free Calculator | Historical Backtesting |
|---|---|---|
| Data Source | Single average return (e.g., "7%") | 98 years of real market data (1928–2025) |
| Worst-Case Scenarios | Not shown | Shows actual 1973, 1929, 2008 outcomes |
| Sequence Risk | Ignored | Tested against real return sequences |
| Inflation Impact | Often uses nominal returns | Real (inflation-adjusted) outcomes |
| Safe Withdrawal Rate | Assumes 4-5% works | Shows what actually survived every period |
Free calculators tell you what works on average. Historical backtesting tells you what works in the worst case. There's a big difference.
How to Protect Yourself
You can't control when you retire. Sometimes it's forced by health, redundancy, or family circumstances. But you can control your risk:
1. Know Your Worst-Case Safe Income
Test your plan against 1973, 1929, and 1969. Find the withdrawal rate that survives even those periods. That's your "floor"—the income you can take no matter what. You might plan to withdraw more, but you know your absolute safe minimum.
2. Build a Cash Buffer
Keep 2-3 years of expenses in cash or short-term bonds. When markets crash, draw from the buffer instead of selling growth assets at a loss. Let your equities recover while you live off cash.
3. Accept You Might Need to Cut Spending
If you retire into a crash, you might need to reduce withdrawals for a few years. Historical data shows those who cut spending 10-20% during the worst years (1974, 1932, 2009) significantly improved their survival odds.
4. Don't Panic-Sell
Markets recovered from 1929. They recovered from 1973. They recovered from 2008. Those who panic-sold at the bottom locked in losses. Those who held on and stuck to their withdrawal plan eventually recovered.
5. Test Before You Retire
Don't wait until you're retired to discover your plan is too aggressive. Test it against historical worst-case scenarios now. If your plan fails in 1973 or 1929, adjust it while you still can.
The Real Lesson
The worst years to retire aren't a secret. They're documented: 1973, 1969, 1929, 2000, 2008. The data exists. What's remarkable is how few people test their retirement plans against this data before retiring.
Free calculators can't show you this. They use averages that hide the worst-case scenarios. They assume sequence risk doesn't matter. They ignore the difference between retiring in 1982 (perfect timing) and 1973 (disaster).
Historical backtesting tells you what actually happened to retirees in every historical period. It shows you what withdrawal rates survived and which ones failed. It removes the guesswork.
That's the value of historical data. Instead of guessing whether 6% is safe, you know. You've tested it against the actual worst periods in history.

Bottom Line
Retirement timing matters. But historical data shows that even the worst timing—1973, 1929, 1969—was survivable with conservative withdrawal rates and disciplined execution.
The key is knowing your worst-case scenario before you retire. Free calculators can't tell you this. They use averages that hide the risk. Historical backtesting shows you what actually happened and what actually works.
Test your plan. Know your floor. Retire with confidence that you've stress-tested against the worst periods in history.
