The Retirement Number Every Single Woman Needs to Know (and How to Calculate Yours)

If you’re a single woman, retirement planning can feel both empowering and overwhelming. On one hand, you call the shots. You get to decide where to live, how you spend and what kind of lifestyle you want in retirement. On the other hand, the full responsibility for funding that future falls on you alone.

That’s why knowing your retirement number matters. It’s the goalpost you aim for, even if it shifts over time. Without it, saving for retirement can feel like guessing in the dark.

Why you should know your retirement number

Most advice out there is written with couples in mind. That’s not our reality. We don’t have a partner’s 401(k) to double the savings rate or spousal Social Security benefits to stretch income. Every dollar of retirement security has to come from us.

We may also need to budget for different safety nets. Health care is a big one, especially if we retire before Medicare eligibility. Long-term care is another, since many of us won’t have children to help if we need support later in life.

At the same time, single women often enjoy more disposable income in their working years, and we get to design a retirement around what matters most to us, whether that’s travel, community, hobbies or all of the above.

Knowing your retirement number helps balance both sides: freedom and responsibility.

How do you figure out your target retirement number?

A common starting point is the rule of 25. Estimate your annual expenses in retirement, then multiply by 25. This comes from the generalized and often touted 4% guideline, which suggests you can safely withdraw 4 percent of your savings each year without running out. For example:

• If you think you’ll need $50,000 a year, the 25x rule puts your retirement number at $1.25 million.
• If you expect closer to $80,000 a year, your target would be $2 million.

It’s a helpful shortcut, but it’s not perfect. The rule doesn’t account for rising health care costs, market volatility or the fact that women tend to live longer than men. For single women, that longevity risk is especially important.

What do the experts say?

For years, a million dollars was the popular “magic number.” These days, experts push much higher figures. Suze Orman has said you may need $5 million to $10 million to retire comfortably. Fidelity’s guidance is different: save 10 to 15 percent of income and aim to have 10x your salary by age 67. Vanguard offers similar benchmarks.

Hearing $5 million can feel daunting, even paralyzing. Don’t let it stop you from setting your own target. The right number for you depends on your lifestyle, income and choices. For some, $1 million may be enough. For others, especially in high-cost cities, it might take $3 million or more.

How lifestyle shapes your number

Because you’re building retirement on your own, lifestyle choices carry even more weight. Consider two examples:

• One woman plans to live in a modest home in a low-cost state, budget about $45,000 a year and keep things simple. Her retirement number could be around $1.1 million.
• Another envisions retiring in a high-cost city, traveling regularly and maintaining her current lifestyle at $150,000 a year. She’d need closer to $3.75 million.

Neither choice is wrong. What matters is knowing what you want and planning accordingly.

Why inflation matters

Inflation is the sneaky factor that makes today’s dollars worth less tomorrow. Groceries, rent and health care all cost more as time goes on, and medical costs rise even faster. That means your retirement number can’t be a “set it and forget it” figure.

Plan to revisit your target every few years. If your expenses, salary or lifestyle plans change, your goal should adjust too.

Simple scenarios to bring it to life

Let’s say you start saving $500 a month at age 25. With a 7 percent return, you could end up with about $1.2 million by age 65.

If you wait until 40 to start but put away $1,200 a month, you’ll have closer to $750,000. Same effort, later start = very different outcome.

Or, think about expenses. Planning for $40,000 a year means a retirement goal of $1 million. Planning for $100,000 a year means a goal of $2.5 million. That’s why personalizing matters.

Making it specific for single women

As single women, we have unique considerations:

• Social Security: Our benefit will be based only on our earnings history, not a partner’s. That means maximizing earnings and delaying benefits if possible can be even more important.
• Health care: If we retire before 65, we need a bridge plan until Medicare. Even after that, supplemental insurance adds costs.
• Long-term care: We may need to plan for paid support, whether through insurance or savings.
• Flexibility: On the plus side, we can choose lower-cost places to live, design retirement around community with friends and focus spending on what brings us joy.

Your retirement number isn’t about hitting someone else’s benchmark. It’s about creating security and freedom for yourself. For some women, that number will be $1 million. For others, it could be $5 million or more. What matters is setting a goal that fits your life, then revisiting it as your circumstances evolve.

It’s not about chasing an intimidating figure. It’s about giving yourself the confidence to know that your future is funded, your independence is protected and your retirement reflects the life you choose.

To make this real, here’s what the 25x rule looks like at different spending levels. If you expect to spend more each year in retirement, your target grows quickly.

Annual Expenses in Retirement	Monthly Expenses (Approx.)	Target Retirement Number (25x Rule)
$50,000	$4,167	$1,250,000
$75,000	$6,250	$1,875,000
$125,000	$10,417	$3,125,000
$150,000	$12,500	$3,750,000
$200,000	$16,667	$5,000,000
