Social Security at 62 vs. 70: The Math Most People Get Wrong

Last month a client sat across from me — 61 years old, still working, no pressing need for income — and told me he was planning to claim Social Security at 62. His reason: "I want to get something out of it before they change the rules."

That's not a strategy. That's anxiety dressed up as a plan.

The claiming decision is genuinely the most consequential financial move most of your clients will make in retirement. Getting it right — or helping them understand why "right" depends heavily on their specific numbers — is one of the clearest ways you demonstrate your value as an advisor.

Here's how to actually run this analysis.

The Numbers First

Your client's full retirement age (FRA) is the anchor. Born in 1960 or later, that's 67. Every month they claim before FRA, their benefit gets permanently reduced. Claim at 62 and they're looking at a 30% haircut. Every year they wait past FRA, they earn an 8% delayed credit — maxing out at 70.

So from 62 to 70, the difference in monthly benefit is roughly 54%. That's not a rounding error. That's a fundamentally different retirement income floor for the rest of their life.

Put real numbers on it. Say the FRA benefit is $2,000/month. Claiming at 62 gives them $1,400. Waiting until 70 gives them $2,480. That's a $1,080/month difference — $12,960 per year — for as long as they live.

The Breakeven Math (And Why It's Only Half the Picture)

The standard breakeven calculation asks: how long until the higher monthly benefit makes up for all the checks you didn't collect?

If they claim at 62 instead of 70, they collect 96 months of $1,400 checks before the person who waited gets their first dollar. That's $134,400 head start.

Divide that by the $1,080/month advantage of waiting: $134,400 ÷ $1,080 = 124 months, or about 10.3 years past age 70. Breakeven age: roughly 80.

Live past 80 and waiting paid off. Die before 80 and early claiming put more total money in their pocket.

Simple enough. But stop here and you're leaving out the part that actually matters for most advisors' clients.

What the Breakeven Misses

The breakeven assumes the money collected early is just sitting there doing nothing. It isn't.

If your client invests those early checks — even conservatively — the math shifts. At a 4% real return, the breakeven age pushes out to 83 or 84. At 6%, it might be 87. For clients in good health with longevity in the family, that's still a clear case for waiting. For a 62-year-old with serious health issues and no family history of making it to 80, the calculus looks different.

The other variable people underweight: the spouse. For married couples, the higher earner's benefit becomes the survivor benefit. When one spouse dies, the surviving spouse keeps the larger of the two checks. A husband delaying to 70 isn't just optimizing for himself — he's buying the highest possible floor for his wife if she outlives him by 10 or 15 years. That changes the analysis entirely.

The IRMAA Wrinkle High-Income Clients Need to Know

Here's one most advisors miss. Clients doing Roth conversions in their 60s — between retirement and Social Security claiming — are often deliberately keeping their MAGI low to avoid IRMAA surcharges on Medicare.

Adding Social Security income changes that calculation. Depending on how much of the benefit is taxable (up to 85% for higher-income clients), claiming early can push income over an IRMAA threshold and trigger $800 to $5,000+ per year in Medicare surcharges. For a couple, double that.

If your client is doing meaningful Roth conversions, model the combined impact before assuming early claiming is the low-tax option.

What to Actually Do With This in Client Meetings

Stop asking "when do you want to start?" and start running scenarios. Specifically:

• Model at least three claiming ages: 62, FRA, and 70
• Show total lifetime benefits at different mortality assumptions (80, 85, 90)
• For married couples, show the survivor benefit outcome for each scenario
• If they have meaningful other income, layer in the IRMAA impact
• Show how the claiming date interacts with their Roth conversion window

When a client sees the actual numbers — not a gut feeling about "getting something out of it" — the conversation changes. Most of them, when they see that waiting from 67 to 70 locks in $12,000+ more per year for life, start asking the right question: "How do I bridge the income gap until 70?"

That's the planning opportunity. That's where the work is.

Key Takeaways

• The 62-to-70 benefit range is roughly 54% — this is the biggest permanent financial lever most clients have.
• Breakeven age is ~80 without investment returns; pushing out past 83-84 when early checks are invested.
• For married couples, the higher earner's delay is really about maximizing the survivor benefit.
• Early claiming can trigger IRMAA surcharges that wipe out some of the perceived "head start."
• Run at least three scenarios with mortality assumptions — the numbers change the conversation more than any explanation will.
