8 Investing Numbers That Shape Whether Your Nest Egg Outlives You

Full analysis

Taylor Schulte, host of the Stay Wealthy Retirement Show, walks through eight historical return figures — from cash to small-cap value stocks — and explains what each one means for a portfolio that has to last 30-plus years. The central argument: the asset that feels safest (cash) is historically the one most likely to erode your purchasing power over a long retirement, while the asset that feels riskiest (stocks) has been the most reliable way to stay ahead of inflation.

What was covered

• Inflation as the hurdle rate. Schulte opens with the 100-year average inflation rate of 3% per year, noting it doubles the cost of living roughly every 24 years. A lifestyle costing $100,000 a year at retirement could cost $240,000 a year by age 90.
• T-bills and cash equivalents (3.3% nominal). Treasury bills — a proxy for CDs, money market funds, and high-yield savings accounts — have returned 3.3% annually over 100 years, barely clearing the 3% inflation hurdle. Real (after-inflation) return: roughly 0.3%.
• Short-term bonds (4.8% nominal). Five-year Treasury notes have returned 4.8% historically, about 1.5 percentage points more than cash. Schulte frames these not as growth assets but as a "war chest" — two to five years of living expenses held so retirees can avoid selling stocks during a downturn.
• Long-term bonds and the duration trap (5% nominal). Twenty-year Treasuries have returned only about 0.2 percentage points more than five-year notes (5% vs. 4.8%), yet carry roughly three times the interest-rate sensitivity. Schulte uses this to warn that taking more risk does not automatically produce more return — it depends on which risk.
• Broad US stocks (10.5% nominal / ~7.5% real). A total US market index has returned 10.5% annually over 100 years, translating to roughly 7.5% real purchasing-power growth — the engine Schulte argues makes a 30-year retirement financially survivable.
• Small-cap value stocks (14.3% nominal). Smaller companies trading at low prices relative to fundamentals have returned roughly 4 percentage points more per year than the broad market over 100 years. Schulte cautions this outperformance arrives in bursts, has gone through decade-long droughts vs. the S&P 500, and requires conviction to hold.
• The 60/40 portfolio (~9% nominal). Blending 60% stocks and 40% bonds has historically returned roughly 9%, capturing most of the stock market's gain at lower volatility. Schulte illustrates the 2000–2009 decade: the S&P 500 lost about 9% per year total, while a plain 60/40 turned in a roughly 33% cumulative gain — but only about 3% annualized, barely ahead of the roughly 2.5% inflation of that period.
• International diversification as a supplement. Since 1974, in every year US stocks returned less than 4%, international stocks outperformed by an average of 2.4%. Schulte cites this to argue that owning assets that don't move together means a retiree drawing income always has something to sell that isn't down.

Notable claims & predictions

• Taylor Schulte: "At 3% inflation, the cost of living roughly doubles every 24 years. A lifestyle that costs $100,000 a year on the day you retire could cost around $240,000 a year near the end." — A concrete planning anchor for anyone projecting 25–30 years of spending.
• Taylor Schulte: "Cash historically did a good job preserving purchasing power but very little to increase it — roughly 0.3% real return over 100 years. Meanwhile, stocks have increased investors' purchasing power by about 7.5% per year." — Framing cash not as safe but as the slow drain.
• Taylor Schulte: "Extending from five years all the way to 20 years only earned you about 0.2% more per year, but a 20-year Treasury could decline 12–14% if yields rise 1 percentage point versus 4–5% for a five-year note — roughly three times the interest-rate sensitivity for a small fraction of the extra return."
• Taylor Schulte, quoting Brian Portnoy: "Diversification means always having to say you're sorry." Applied to small-cap value, which has underperformed the S&P 500 for stretches of a decade or more even with superior long-run numbers.
• Taylor Schulte: "Since 1974, in every single year when US stock returns were less than 4%, international stocks outperformed by an average of 2.4%." — Offered as a practical reason to hold international exposure during retirement, not just for long-term growth.
• Taylor Schulte: "The safest-feeling choice can end up being the riskier one" — the framing that underpins the whole episode: the risk of outliving your money is just as real as the risk of a market loss.

Fact check

The 3% long-run US inflation figure is consistent with commonly cited historical data and is a reasonable planning assumption, though the actual century-long average depends on the start and end dates used. Not misleading.

The 10.5% long-run nominal US stock return is in the range typically cited for broad US equities using data going back to the 1920s (Ibbotson/Morningstar series). Widely reported and plausible, though exact figures vary by data source, time period, and whether dividends are reinvested. Schulte does not name his data source, so readers should treat this as an approximation consistent with mainstream historical research, not a precise verified number.

The 14.3% return for small-cap value stocks is a frequently cited figure from academic factor research (Fama-French). That research is real and peer-reviewed. However, Schulte does not name the data source, and it's worth knowing that the small-cap value premium has been debated since it was published — partly because awareness of the premium may reduce it going forward, and partly because the outperformance has been weak in the US over the past decade-plus. Schulte acknowledges the drought but presents the 100-year figure without flagging that more recent data is considerably less favorable. Readers should treat 14.3% as a historical data point, not a forward projection.

"In every single year since 1974 when US stocks returned less than 4%, international stocks outperformed by an average of 2.4%" — This is a specific empirical claim Schulte attributes to his own past episode (Episode 260). It cannot be independently verified from the transcript alone. The directional point — that international stocks have at times cushioned poor US years — is supported by general diversification research, but "every single year" is an unusually strong claim. Take it as a useful illustration of the diversification argument, not a verified historical law.

Duration sensitivity example (5-year Treasury down 4–5% vs. 20-year down 12–14% on a 1-point yield rise) — These are rough approximations consistent with standard bond duration math. Schulte appropriately flags they depend on coupon and other factors. Not misleading; the directional point is sound.

No incentive conflict to flag: Schulte is a fee-based financial adviser (Define Financial) who runs a podcast. He is not selling a specific product in this episode. His firm offers a "Total Retirement System" consultation, mentioned briefly. The investment philosophy he describes — broad diversification, low-cost index funds tilted toward factors — is consistent with academically mainstream advice rather than a product pitch.

Why this matters for you

• The inflation math is a concrete planning check. If you are 60–65 and expect to live into your late 80s or 90s, Schulte's 3% compounding framework gives you a specific reason to stress-test whether your portfolio — not just its dollar balance but its real purchasing power — holds up over 25–30 years. Ask your adviser: what is our projected real (after-inflation) return, and does it fund the spending plan through age 90?
• Heavy cash positions carry a hidden cost. If you are holding significantly more than two to three years of living expenses in CDs, money markets, or high-yield savings, the episode's numbers suggest that excess cash is likely earning little to nothing in real terms over time.
