Retirement Planning for Women — What I Wish I'd Known About the Longevity Gap

 

There's a conversation I keep having with women in their forties and fifties who are starting to take retirement seriously. They've been contributing to their 401(k), they have some savings, they broadly understand that they need to be prepared. And then we start looking at the actual numbers and something becomes clear: they've been planning for a retirement of roughly twenty years, because that's what the standard tools assume, and that assumption is probably wrong.

Women in the US live to an average of about 79. But averages are misleading for planning purposes. If you're a healthy 50-year-old woman, your probability of living to 90 or beyond is not negligible — it's substantial. Planning for a twenty-year retirement when you have a real possibility of a thirty-five-year one isn't conservative planning. It's planning with a gap that compounds over time into a serious problem.

The longevity gap is the reason why retirement planning for women requires a different framework than the standard one — not more aggressive investing necessarily, but longer time horizons, lower initial withdrawal rates, more attention to inflation protection over decades rather than years, and more deliberate planning for healthcare costs that accumulate significantly in later life.

But it's not just longevity. The career interruption problem is one I've seen affect a surprising number of women who would not have described themselves as having had "interrupted careers." Taking two years off for a first child. Shifting to part-time for several years during school-age years. Taking six months when a parent needed care. These feel like small pauses at the time. In retirement savings terms, they're permanent reductions to the contribution base and the compound growth that runs on top of it.

The Social Security implication alone is worth understanding clearly. Your Social Security benefit is calculated on your highest 35 earning years. If you have fewer than 35 working years, the missing years count as zeros in the calculation. Career interruptions that feel minor can meaningfully reduce a lifetime of Social Security income.

None of this is meant to be alarming. It's meant to be specific, because specific is what makes planning useful. The Retirement Strategy for Women Planner works through these specifics systematically — longevity modeling, career break impact analysis, Social Security optimization, healthcare exposure, and solo retirement planning for the significant percentage of women who will spend part of their retirement without a partner's income to rely on.

It's the kind of analysis that turns "I think I'm roughly on track" into "I know exactly where I stand and what I need to adjust." The planner is on Etsy here — instant download, printable PDF.
