Most Couples Make the Same Assumption

Many married couples make a simple Social Security plan:

Primary: claim at 67.
Spouse: claim at 67.

It feels logical.

But for some households, claiming at the same age may leave meaningful income on the table.

The better question is not:

When should each person claim?

The better question is:

What claiming strategy creates the strongest household income plan?

Why Social Security Is a Household Decision

Social Security is often treated like an individual benefit.

For married couples, it is usually a household strategy.

Claiming decisions can affect:

  • Monthly retirement income
  • Portfolio withdrawals
  • Survivor benefits
  • Lifetime household benefits
  • Retirement income coverage

The highest benefit for one person does not always create the best outcome for the couple.

A Simple Example

A couple may start with this plan:

Primary: claim at 67.
Spouse: claim at 67.

After testing different options, a better strategy may be:

Primary: claim at 65.
Spouse: claim at 70.

That may sound surprising.

But one spouse claiming earlier can help cover near-term income needs, while the other spouse delaying can increase future guaranteed income.

Why Different Claim Ages Can Increase Retirement Income

Many couples assume both spouses should claim Social Security at the same age.

Often, that is not the best strategy.

When one spouse claims earlier and the other delays benefits, the household may receive:

  • More income throughout retirement
  • Higher survivor benefits
  • Fewer portfolio withdrawals
  • Greater lifetime Social Security benefits

Example Impact

Current Strategy:

Primary: claim at 67.
Spouse: claim at 67.

Optimized Strategy:

Primary: claim at 65.
Spouse: claim at 70.

Potential Impact:

Monthly Income: +$2,800/month
Coverage: 79% → 105%
Lifetime Benefit: +$101,000+

The goal is not to maximize one person's benefit.

The goal is to maximize the household's retirement income.

Why This Works

A coordinated strategy can help in three simple ways.

1. It can improve early cash flow

If one spouse claims earlier, that income may help cover spending needs in the first years of retirement.

That can reduce the amount withdrawn from savings.

2. It can improve later income

If one spouse delays benefits, that benefit may be larger later in retirement.

That can help protect the household if retirement lasts longer than expected.

3. It can improve survivor protection

If the higher benefit is delayed, the surviving spouse may have a stronger income base later.

That can matter a lot if one spouse outlives the other by many years.

The Biggest Mistake Retirees Make

The biggest mistake is not always claiming too early.

It is not always claiming too late.

The biggest mistake is never comparing options.

Many households never test:

  • Both claim at 67
  • One claims at 65 and the other at 70
  • One claims at 67 and the other at 70
  • Both delay to 70
  • One claims early to reduce portfolio withdrawals

Without comparing strategies, it is hard to know which option actually improves the plan.

What Couples Should Ask Before Claiming

Before deciding when to claim, ask:

  • Do we need income immediately?
  • Which spouse has the larger benefit?
  • What happens if one spouse lives much longer?
  • How much will we need from our portfolio before Social Security starts?
  • Does delaying one benefit improve long-term income?
  • Which option gives us the best household outcome?

These questions are more useful than simply choosing a popular claiming age.

Key Takeaways

  • Married couples should treat Social Security as a household decision.
  • Claiming at the same age is not always the best strategy.
  • One spouse claiming earlier while the other delays can improve retirement income.
  • Coordinated claiming may reduce portfolio withdrawals.
  • A delayed benefit may improve survivor protection.
  • Testing multiple claiming strategies can reveal better outcomes.
