Planning as a Couple: Two Ages, Two Claiming Decisions, One Portfolio

Two People Are Not One Bigger Person

The easiest way to plan for a couple is to add everything together: one combined portfolio, one combined Social Security check, one retirement date. It's also the most flattering way, and it misses three things that make a couple's plan different:

1. Two ages. Partners rarely retire, reach Medicare, or claim Social Security in the same year.
2. Two claiming decisions. Each partner chooses when to start Social Security, and the choices affect each other.
3. The survivor years. One partner will very likely outlive the other, often by many years, on noticeably less income.

The third one is where combined plans go most wrong. To show how much it matters, this guide works through a single example household in the RetireOps calculator.

The Example Household

• Ages: 58 and 55. Both plan to stop working when the older partner turns 62.
• Portfolio: $1.5M in total: $400k taxable, $900k tax-deferred (401(k)/IRA), $200k Roth. They save $50k a year until they retire.
• Spending: $86,400 a year in today's dollars, plus healthcare.
• Healthcare: $900 a month per person before Medicare, $425 a month per person after.
• Social Security at 67: $3,200 a month for the older, higher-earning partner and $1,500 for the younger partner.
• Life expectancy: 88 for the older partner, 93 for the younger.

Step 1: Add Your Partner

Open Social Security & Medicare in the sidebar and turn on Include a spouse or partner. Four inputs appear: your partner's current age, the age they'll claim Social Security, their monthly benefit at that age, and their life expectancy.

Once your partner is added, the calculator changes how it runs the plan:

• The plan runs until the last survivor. Here that's the younger partner's 93rd birthday, eight years after the older partner's projected death at 88. The age column in the yearly table always shows the older partner's age, so the plan ends at "96".
• Healthcare is charged per person, on each person's own clock. When the older partner turns 65 and moves to Medicare, the younger one is still 62 and still buying private coverage for three more years.
• Taxes use married-filing-jointly brackets while both partners are alive.

Step 2: The Survivor Years

After the first death, three things change at once, and none of them help:

1. One Social Security check stops. The survivor keeps the larger of the two benefits, not both. Our household loses the $1,500 check, permanently.
2. Spending barely moves. The house, the car, the property tax and the utilities stay mostly the same. The calculator keeps the spending target unchanged and drops only the deceased partner's healthcare.
3. Tax filing switches to single. Single brackets are roughly half the width of joint brackets, so the same income is taxed at a higher rate, at exactly the moment income has dropped.

Planners call this combination the survivor's penalty (or "widow's penalty"). You can see it in the Yearly Financial Projection table. Click any row to see that year's breakdown.

Compare the last year with both partners alive (88) to the first survivor year (89):

• Social Security: $56,400 → $38,400
• Healthcare: $21,017 → $10,765
• Estimated taxes: $10,058 → $14,831
• Drawn from the portfolio (before tax): $51,017 → $58,765

The survivor has $18,000 less Social Security income, and their tax bill goes up by almost half. The deceased partner's healthcare costs go away, but that saving doesn't make up for the lost benefit and the higher tax bill. The portfolio has to make up the difference every year for the rest of the survivor's life.

Step 3: Why Combining Everything Overstates Your Confidence

Here's how the same household scores when planned as one person versus two:

• Planned as one person, with the combined $4,700 benefit and the older partner's life expectancy: 95% confidence.
• Still one person, but with both partners' healthcare bills and a plan long enough for the younger partner: 85%.
• Modelled as two people with the survivor rules: 80%.

That's 15 points of confidence that don't really exist. The one-person plan looks finished at 95%. The real plan sits well below the 90% target that professional benchmarks use.

The panel's second number, If you reach 100, reruns the plan as if both partners live to 100. For couples this matters more than for single people: the chance that at least one of you lives into your late 90s is much higher than the chance that either of you does.

Step 4: Use the Claiming Decision That Protects the Survivor

The survivor keeps the larger benefit, so the higher earner's claiming age decides the survivor's income for life. That makes it the biggest lever a couple has.

Our household's results already suggest this: the Adjust Your Social Security Timing card recommends the older partner wait three more years, to 70, which raises their benefit from $3,200 to $3,968 a month. Here's how that compares with other claiming choices:

• Both claim at 62: 76% confidence, 71% if you reach 100. The survivor receives $26,880 a year.
• Both claim at 67: 80% and 77%. The survivor receives $38,400 a year.
• Higher earner at 70, lower earner at 62: 83% and 79%. The survivor receives $47,616 a year.
• Higher earner at 70, lower earner at 67: 84% and 80%. The survivor receives $47,616 a year.

Three things stand out:

• Delaying the higher earner raises the survivor's income by $9,216 a year compared with claiming at 67, for as long as the survivor lives. Confidence rises 4 points, and 3 if you both reach 100.
• The lower earner's claiming age barely matters for the survivor. Their check stops at the first death no matter what, so claiming it early mainly provides cash during the years before the larger benefit starts. Here that costs just one point of confidence.
• Claiming both benefits early is the worst option on every measure. It locks the survivor into the smallest check.

Delaying is not free. While it waits for the larger check, our household draws about $38,400 more from the portfolio each year from 67 to 70, roughly $115,000 in total. For more on funding that gap, see our guide to Social Security Bridging.

Step 5: Close the Rest of the Gap

Delaying gets this household to 84%. The calculator's Any One of These Reaches 90% cards show the remaining options, and each one is a conversation to have together:

• Work a little longer. One or two more years of saving and not drawing down can close a gap that the claiming decision alone can't.
• Plan for the survivor's spending, not just the couple's. If you would sell the house or move somewhere cheaper after the first death, enter the sale as a One-Time Income at that age. If you're unsure, leave it out: a plan that only works if the survivor moves isn't a plan the survivor chose.
• Use the gap years for Roth conversions. A survivor filing single with a large tax-deferred balance faces higher brackets and required minimum distributions. Converting while you still file jointly, in the low-income years before Social Security starts, moves that tax to a year when the brackets are twice as wide.

What the Calculator Doesn't Model

Social Security's family rules have more detail than any planning tool captures. Keep these in mind when you enter your numbers:

• Spousal benefits aren't added automatically. A lower earner can receive up to half of the higher earner's full-retirement-age benefit if that's more than their own. If that applies to you, enter the spousal amount from your Social Security statement as your partner's benefit.
• Survivor benefits are simplified. The calculator gives the survivor the larger of the two benefits you entered. Real survivor benefits can be lower if the survivor claims before their own full retirement age, or if the deceased claimed early.
• The partner who dies first is set by the life expectancies you enter. Swap them and rerun the plan. If the lower earner outlives the higher earner by a long time, the survivor years cost more.

The Takeaway

A couple's retirement plan has to work for two people and then for one. The one-person phase is where combined plans fail: a lost benefit, a narrower tax bracket, and a spending target that barely moves.

1. Model both partners, each with their own age and life expectancy.
2. Check the survivor years in the yearly table, not just the headline score.
3. Let the higher earner delay if the portfolio can fund the wait. It's the cheapest protection for the survivor.
