Start with separate numbers, then combine them

Retirement planning with a spouse means building one financial picture from two separate work histories, two different ages, and two sets of accounts. The first step is not to merge everything — it is to write down what each of you has right now: your current age, your expected retirement age, your salary, your 401(k) or 403(b) balance, your IRA balance, any pension, and your Social Security statement (which you can request free at ssa.gov). Do this separately, even if one spouse has not worked recently.

Once you both have your numbers, add them together to see your household retirement picture. This is the only number that matters for planning: your combined savings, your combined income sources, and your combined time until retirement. Many couples discover at this stage that one person's retirement account is much larger than the other's, or that one spouse will receive a pension while the other will not. These differences are not problems — they are facts that shape your strategy.

Key Takeaways

  • Write down each spouse's age, retirement date, current savings, and Social Security statement separately before combining them into one household plan.
  • Decide together whether you will retire at the same time or stagger your retirements, because this changes how much you need to save and when you can stop working.
  • Coordinate your 401(k) contributions and IRA accounts so you are not duplicating employer matches or missing tax deductions available to married couples.
  • Review your beneficiary designations on every account — 401(k)s, IRAs, life insurance, and bank accounts — because they override your will and must name each other or your children explicitly.
  • Plan for Social Security as a household decision, not two individual ones, because one spouse's claiming age affects the other's survivor benefits.

Decide whether you retire together or one at a time

The biggest choice couples make is whether both spouses stop working in the same year or whether one retires first. This decision changes your savings target and your cash flow for years. If you retire together, you need enough saved to cover both of you from that date forward. If one spouse retires early while the other keeps working, the working spouse's income covers household expenses and lets the retired spouse's savings grow longer.

Staggered retirement is common when spouses are different ages or when one person has a pension that starts at a specific age. For example, a spouse with a military pension might retire at 42 while the other spouse works until 65. The pension covers living expenses, the working spouse's salary funds retirement accounts, and both accounts grow until the second retirement date. Write down both scenarios — same-year retirement and staggered retirement — and calculate how much you need to save under each one. The scenario that requires less total savings is usually the one that makes sense, unless other factors (like health, job satisfaction, or caregiving) point elsewhere.

Coordinate your employer retirement accounts to avoid waste

If both spouses work, you likely have two 401(k)s or 403(b)s. The most common mistake is to contribute to both accounts without checking whether you are both getting an employer match. An employer match is information programs — it is the employer's contribution to your account, usually 3 to 6 percent of your salary. If your employer matches and you are not contributing enough to capture it, you are leaving money on the table.

The strategy is straightforward: make sure each spouse contributes enough to their own plan to capture the full match. If one spouse's employer does not offer a match, or if you have extra money to save beyond the match, direct that money to the spouse with the better plan — lower fees, better investment options, or a Roth option if you want tax-free growth. You can also use a spousal IRA if one spouse has little or no income. A spousal IRA lets a non-working or low-earning spouse contribute to an IRA based on the working spouse's income, which is useful if one of you took time out for caregiving.

Name each other as beneficiary and review it every few years

Beneficiary designations on 401(k)s, IRAs, life insurance policies, and some bank accounts override your will. If you name your spouse as beneficiary and then divorce without updating the form, your ex-spouse may still inherit that account. If you do not name anyone, the account goes through probate, which is slow and costly. The rule is straightforward: name your spouse as the primary beneficiary on every account that allows it, and name your children or a trust as the contingent beneficiary in case your spouse dies before you do.

Review these designations every three to five years or after any major life change — a marriage, a divorce, a birth, or a death in the family. Many people fill out the beneficiary form once when they open an account and never look at it again. Your employer's HR department or your bank can tell you who is currently named on each account. If the form is old or blank, update it when ready. This is one of the few financial tasks that takes 15 minutes and can save your family thousands in probate fees.

Plan Social Security as a couple, not as individuals

Social Security is not just your own benefit — it is a household income source that depends on both spouses' work histories and both spouses' claiming ages. The most common strategy is for the higher earner to delay claiming until 70 (when the benefit is largest) while the lower earner claims at 62 or 67. This maximizes the household's lifetime benefit because the higher earner's larger check grows for eight more years, and the surviving spouse gets a larger survivor benefit if the higher earner dies first.

If both spouses earned similar amounts, you have more flexibility. You might both claim at 67, or one might claim early at 62 while the other waits. The math depends on your life expectancy, your other savings, and your household expenses. The Social Security Administration publishes a free online calculator at ssa.gov that shows how different claiming ages affect your household benefit. Run the numbers for several scenarios — both claim at 62, both claim at 67, one claims at 62 and one at 70 — and see which one produces the most household income over your lifetime.

Account for the spouse who took time out of the workforce

If one spouse spent years out of work for caregiving, that gap shows up in a lower Social Security benefit and smaller retirement savings. Social Security credits are based on 35 years of earnings, so years with zero income count as zeros in the calculation. A spouse who worked 25 years instead of 35 will have a smaller benefit, even if they earned the same amount per year as their partner.

You cannot change the past, but you can plan for it. The working spouse should prioritize saving in a spousal IRA (if the non-working spouse has little income) or in a regular taxable account in the non-working spouse's name. This builds retirement savings outside the 401(k) system and gives the non-working spouse their own assets at retirement. You should also discuss whether the working spouse will work longer to make up for the household's lower total savings, or whether you will retire on a smaller income. These are not straightforward conversations, but they are necessary ones.

Decide how to handle debt before retirement

Debt in retirement is harder to manage because you have no paycheck to cover the payment. If either spouse has a mortgage, car loan, student loan, or credit card balance, decide together whether to pay it off before retirement or carry it into retirement. A mortgage at 3 percent might make sense to carry if your retirement savings earn more than 3 percent. A credit card balance at 18 percent should be gone before you stop working.

Run the numbers both ways: one scenario where you pay off all debt before retirement (which means saving less in retirement accounts), and one where you carry some debt and make payments from retirement income. The scenario that leaves you with the most total assets at retirement is usually the right one. If you have a large mortgage and limited savings, you might need to work longer, downsize your home, or both.

Create a written plan and update it annually

After you have done all this work, write it down. Your retirement plan should include: both spouses' current age and target retirement age, combined household savings, combined household income sources (Social Security, pensions, part-time work), annual spending target, and the year you plan to retire. Add one page that shows what happens if one spouse dies early or becomes unable to work — how would the surviving spouse's income change, and is there enough life insurance to cover the gap?

Review this plan once a year, usually around tax time or on an anniversary. Update it with your new account balances, any raises or job changes, and any changes to your retirement date. If the numbers have shifted — if you saved more than expected or if one spouse got a promotion — recalculate whether you can retire on schedule or whether you need to adjust. Retirement planning is not a one-time event; it is a conversation you have with your spouse every year until you retire, and then occasionally in retirement to make sure you are on track.

Frequently Asked Questions

What if one spouse is much older than the other?

Age gaps change the timeline but not the strategy. The older spouse may retire first while the younger one keeps working, or you may plan for a staggered retirement where the older spouse retires at 65 and the younger at 70. Run the numbers for both scenarios and see which one gives you the most household income. You will also want to coordinate Social Security claiming — the older spouse might claim at 62 while the younger waits until 70.

Can we split a 401(k) in a divorce?

Yes, but only with a may have access to Domestic Relations Order (QDRO), a court document that tells the plan administrator how to divide the account. Without a QDRO, you cannot split a 401(k) without penalties. If you are going through a divorce, ask your lawyer to prepare a QDRO and make sure both spouses update their beneficiary designations afterward. This is one of the few times you should involve a lawyer in retirement planning.

What if one spouse has a pension and the other does not?

A pension is a may provide income source, so it changes your retirement math. If one spouse has a $2,000-per-month pension starting at 65, that covers part of your household expenses and reduces how much you need to save. The other spouse should focus on building their own retirement accounts. You might also decide that the spouse without a pension works longer to build more savings, or that the spouse with the pension retires first and the other keeps working.

Should we have joint or separate retirement accounts?

Most couples keep their 401(k)s and IRAs separate because they are tied to individual employers and individual work histories. You can have a joint savings account or joint taxable brokerage account for extra retirement savings. The advantage of joint accounts is simplicity; the disadvantage is that they go through probate if one spouse dies. Name each other as beneficiary on individual accounts instead, which avoids probate and is simpler than joint ownership.

What happens to my spouse's Social Security if I die first?

Your spouse can receive a survivor benefit based on your earnings record, even if they have not yet claimed their own benefit. The survivor benefit is usually 75 to 100 percent of what you were receiving or may have access to to receive. This is why delaying your own claim can help your spouse — a larger benefit for you means a larger survivor benefit for them. Discuss this with your spouse and factor it into your claiming strategy.
