Retirement Planning for Singles: Building Wealth on One Income

The Structural Difference

Why Retirement Is Different When You Are Single

Married retirees have structural advantages that single retirees do not: spousal Social Security benefits (up to 50% of the higher earner’s benefit), survivor benefits (100% of the deceased spouse’s benefit if higher), shared housing costs, and a built-in caregiver during health crises. These are not minor perks — spousal Social Security alone can add $15,000–$20,000 per year to a married couple’s retirement income. As a single retiree, that income does not exist.

Long-term care is the largest financial risk specific to single retirees. The median cost of a private nursing home room exceeds $108,000 per year. Married couples can care for each other at home, deferring or avoiding facility costs. Single retirees must plan — and pay — for professional care from the start. Without a long-term care strategy, a single health event can consume decades of savings in under three years.

But single retirees also have advantages. No divorce risk — the single largest wealth-destruction event in retirement. No lifestyle compromise — you retire when your number is hit, not when a partner’s timeline allows. No survivor’s financial crisis — you never face the shock of losing a spouse’s income or navigating benefits alone. And lower total spending — one person’s retirement is structurally cheaper than two, even if per-person costs are higher. The key is planning for the right number and the right risks.

Social Security for Single Filers

Social Security was designed with married couples in mind. A married person can claim benefits on their own work record or up to 50% of their spouse’s benefit — whichever is higher. A surviving spouse can claim 100% of the deceased spouse’s benefit. An unmarried retiree gets none of this. You receive benefits based solely on your own 35 highest-earning years, period.

This means maximizing your earnings during your working years is doubly important. Social Security benefits are calculated from your top 35 years of inflation-adjusted earnings. Years with zero or low earnings pull the average down. Every year you earn at or above the Social Security wage base ($176,100 in 2025) is a year that maximizes your future benefit. Career breaks, part-time years, and low-earning years cost you more as a single filer because there is no spousal benefit to compensate.

Delay claiming to age 70 if you can. Your benefit increases roughly 8% for each year you delay past your full retirement age (67 for most current workers). Claiming at 62 permanently reduces your benefit by up to 30%. Claiming at 70 gives you the maximum possible benefit — and for a single retiree with no survivor benefits to fall back on, that higher monthly check is worth the wait. Bridge the gap between retirement and age 70 with taxable account withdrawals or Roth IRA distributions (which do not count as income for Social Security taxation purposes).

Long-Term Care Planning Without a Spouse

This is the conversation most financial advisors skip with single clients — and it is the one that matters most. Approximately 70% of people over 65 will need some form of long-term care. Married couples can provide informal care for each other, delaying or avoiding professional costs. As a single retiree, your first need for assistance means hiring a professional — home health aide ($30/hour), assisted living ($54,000/year median), or nursing home ($108,000/year median).

Three strategies to address this risk. Self-insure by building a dedicated long-term care fund — $200,000–$300,000 in today’s dollars, set aside in a conservative allocation separate from your retirement portfolio. Buy a hybrid life/LTC insurance policy in your 50s — these combine a death benefit with long-term care coverage, and unlike traditional LTC policies, you get your money back (as a death benefit) if you never need care. Plan your housing trajectory — continuing care retirement communities (CCRCs) allow you to enter while healthy and transition to higher levels of care as needed, often at locked-in rates.

The worst strategy is no strategy. Ignoring long-term care risk as a single person is the financial equivalent of driving without insurance — it works until it does not, and when it fails, it fails catastrophically. Address it in your 40s or 50s when premiums are manageable and your options are broadest.

Estate Planning for Unmarried Adults

Without a legal spouse, the law does not know who you want making your medical decisions, managing your finances if incapacitated, or inheriting your assets. Default intestacy laws distribute your estate to blood relatives — not your partner, not your best friend, not the person you actually trust. This is not a married-person problem. This is specifically and urgently a single-person problem.

Four documents every unmarried adult needs: a will (directs asset distribution), a durable power of attorney (designates someone to manage your finances if incapacitated), a healthcare proxy (designates someone to make medical decisions), and beneficiary designations on all financial accounts (these override your will — review them annually). Without these, a court decides everything. With them, your wishes are legally binding. An estate planning attorney can prepare all four for $500–$1,500.

Single adults also face higher estate tax exposure in one specific scenario: the unlimited marital deduction does not apply. A married person can leave unlimited assets to their spouse tax-free. An unmarried person’s estate above the federal exemption ($13.61M in 2025) is taxed at 40%. For most singles, this is not an issue — but if you are building significant wealth, consider strategies like irrevocable trusts, annual gifting, or donor-advised funds to manage estate tax exposure.

Summary

Key Takeaways

• Use a 3.5% withdrawal rate, not 4%. Without a spouse’s income as buffer, the more conservative rate adds a critical safety margin against sequence-of-returns risk.
• Delay Social Security to 70. Each year past full retirement age adds ~8% to your benefit permanently. With no spousal benefit to fall back on, maximizing your own record is essential.
• Long-term care is your biggest single-specific risk. Self-insure ($200K–$300K dedicated fund), buy a hybrid life/LTC policy in your 50s, or plan housing through a CCRC. Do not ignore this.
• Estate planning is not optional for unmarried adults. Without a spouse, the law does not know your wishes. Four documents — will, POA, healthcare proxy, beneficiary designations — cost $500–$1,500 and prevent catastrophe.
• Maximize earnings across 35 years. Social Security is calculated from your top 35 earning years. Low-earning years dilute your benefit. Career breaks cost singles more because there is no spousal benefit to compensate.
• Roth accounts create tax-free retirement income. Without a spouse’s deductions to offset traditional 401(k) withdrawals, single retirees face higher tax bills. Roth distributions are not taxed and do not trigger Social Security taxation.
