How Much Do I Actually Need to Retire Alone?

The financial industry is built for pairs. Every retirement calculator asks for "Your Spouse's Income." Every stock photo shows a silver-haired couple walking on a beach. If you're planning for one, the math looks different—and in some ways, it's actually more straightforward.

Let's talk about the "Solo Tax" and the "Solo Strategy." Yes, it costs more to live alone per person. But you also have 100% control over the burn rate.

The Realities of Solo Math

The standard retirement rule is that you need about 70-80% of your pre-retirement income to maintain your lifestyle. For solo women, that number might be closer to 90% if you plan to stay in a house with a mortgage. You don't have the "economies of scale" of sharing a kitchen, utility bills, or car insurance.

If you're starting at 45, or 50, or 55

You're not late. You're motivated. A few things work strongly in your favor:

• •

  Catch-up contributions. From age 50, you can put an extra $8,000 a year into a 401(k) and an extra $1,100 into an IRA (2026 limits). From 60 to 63 the 401(k) catch-up rises to $11,250.

• •

  Delaying Social Security. Every year you wait past full retirement age (67 for most), your check grows 8 percent, permanently, up to age 70, for a maximum bump of 24 percent. It pays off if you expect a long life. Single women often do.

• •

  Working one or two years longer. Painful to hear, powerful in effect. Fewer years to fund, more years to save.

Where to start

In this order: build a three-to-six-month emergency fund (you're the whole safety net). Grab any employer 401(k) match (it's free money). Pay off high-interest debt. Then fill the retirement accounts, and keep the investments boring: broad, low-cost index funds beat stock-picking for almost everyone.

The non-money part

Two things solo planning needs that couple planning skips. Look at long-term-care insurance in your 50s (it gets expensive fast after 60), or earmark savings for care. And do the paperwork: a will, a durable power of attorney, and a healthcare proxy, so the people you choose can act for you. Our Resources page has fee-only planners and simple estate-planning services vetted for exactly this.

One last thing. The research on single women and money keeps finding the same pattern: we're better savers and investors than we think, and worse at believing it. You don't need a husband to retire well. You need a number, a boring portfolio, and time. Two of those you can start on tonight.
