1. Longevity Risk — Outliving Your Money
The risk that you (or your spouse) live longer than your savings. A 65-year-old healthy non-smoking female has a meaningful chance of reaching 95 or beyond. Joint life expectancies for healthy 65-year-old couples often run to age 92+ for at least one spouse. Plans built around the "average" outcome leave half of households short.
2. Inflation Risk — The Quiet Erosion
At 3% annual inflation, the same fixed dollar amount loses about 26% of its purchasing power over 10 years and 59% over 30 years. Pensions without COLAs, level annuity payouts, and bond ladders all face this risk. See our Pension & Lump-Sum Decisions page for more.
3. Sequence-of-Returns Risk — The Order Matters
Two retirees with identical average returns can have very different outcomes if one happens to retire just before a bear market. Withdrawing from a falling portfolio early in retirement can cause permanent impairment to the plan's longevity that the same withdrawals from a rising portfolio would not. This is why "average return" assumptions can mislead.
4. Healthcare and Long-Term-Care Risk — The Variable That Wrecks Plans
Most retirement plans assume routine healthcare costs. The plans that fail are usually the ones blindsided by extended care — multiple years of memory care, in-home aides, or nursing home stays. See our Long-Term Care page for what care actually costs.
5. Behavioral Risk — The Hardest to Quantify
The risk that you panic-sell in a bear market, give too much to family members, fall for a fraud, or simply make decisions in your 80s that your 60-year-old self would not have made. The right plan accounts for cognitive decline as a real possibility, not a worst-case.
A retirement income plan that fails to address all five of these risks is incomplete — even if the math looks good on paper.
