Mini Case · Assured
Ruth and Carlos each have a $1 million investable balance. One needs $44,000 from it next year; the other needs $16,000.
Why doesn't $1 million mean the same retirement for Ruth and Carlos?
Ruth's fictional household spends $80,000 and has $36,000 of stated retirement income. Carlos's spends $56,000 and has $40,000 of income. Each starts with the same $1 million balance.
The tension
A round savings target promises certainty, but neither household spends the target. Their portfolios must cover the gap left after income meets spending—and those gaps are nowhere near equal. The balance is meaningful only after the life around it becomes visible.
What the math clarifies
In these fictional first-year snapshots, the same $1,000,000 balance faces a $44,000 annual gap for household A and a $16,000 gap for household B. That is 4.4% versus 1.6% of the same balance—not a conclusion about either household's safe withdrawal rate.
How to think it through
- Start with each household's annual spending and reliable income instead of treating $1 million as a complete retirement plan.
- Compare the first-year dollar gap and its share of the same balance without calling either percentage a safe withdrawal rate.
- Then test taxes, inflation, longevity and portfolio risk separately; this snapshot explains the gap, not whether either retirement is secure.
What the calculation can—and cannot—settle
A balance does not explain a retirement plan by itself. The limited comparison makes spending and specified income visible, while leaving investment returns, taxes, inflation, longevity and portfolio allocation outside the calculation.
Check the calculation
| Shared fictional investable balance | $1,000,000 |
|---|---|
| Household A annual essential spending | $80,000 |
| Household A stated annual retirement income | $36,000 |
| Household A annual gap | $44,000 · 4.4% of balance |
| Household B annual essential spending | $56,000 |
| Household B stated annual retirement income | $40,000 |
| Household B annual gap | $16,000 · 1.6% of balance |
| Household B gap after equalizing income | $20,000 |
What could change the answer
If household B's stated retirement income is changed to the same $36,000 as the supplied comparison, its gap becomes $20,000. A $24,000 difference remains because the fictional spending levels differ.
