The $220K Shadow on Every "Wait Until 70" Recommendation

Most advisors carry a number in their head. The number is 70.

Wait until 70. Get the bigger check. Tell that to enough clients enough times and it stops feeling like advice and starts feeling like math.

It isn't.

For high-net-worth households (HNW), "wait until 70" carries a number on the back of it that nobody puts on the slide. That number is roughly $220,000 — the after-tax capital advantage the affluent claimer who takes Social Security at 62 holds over the affluent claimer who waits, by the time both of them turn 70.

That is not a rounding error. That is the shadow on every default delay recommendation that hasn't priced the opportunity cost of capital.

Where the number comes from

The CFA Institute ran the comparison in 2026, modeled for an affluent retiree who does not need the early Social Security check to cover living expenses. Two paths. Same client.

Path A — Default delay. Skip the early benefit. Wait until 70. Collect the larger monthly check for life. From 62 to 70: zero Social Security income.

Path B — Claim at 62, invest the proceeds. Take the reduced benefit (about 30% smaller than the full retirement age amount). Run it through a conservative portfolio. Pay taxes. Reinvest what's left.

By age 70, Path B is sitting on roughly $220,000 in additional after-tax capital that Path A does not have. The early claimer's monthly check is permanently smaller. The early claimer's household balance sheet is permanently larger.

That trade-off doesn't show up in the standard claiming-strategy conversation because the standard conversation only looks at one variable. The check.

For affluent households, the check is the input. The output is what the money does once it lands.

Why the conventional advice misses this

"Delay to 70" is built for a household whose Social Security check is the central retirement-income variable. For most Americans, that's correct. The average lifetime cost of suboptimal claiming runs around $111,000 — and most of that loss lands on households where every dollar of monthly benefit matters.

HNW households are a different problem.

When the early Social Security income is not needed for spending, it doesn't disappear into a checking account. It compounds. Over eight years, with conservative assumptions and realistic taxes, that compounding produces a number that looks a lot like a strong portfolio's annual return rolling forward — because that's what it is.

The advisor who recommends delay without naming the $220,000 is not necessarily wrong. They are incomplete.

There is a difference.

The condition (because this is conditional)

Early claiming is not the new default. We are not advocating affluent clients claim at 62 and call it strategy. The cases where Path B wins on capital can still lose on other dimensions:

Survivor protection. If the higher earner dies first and the surviving spouse will rely on the larger benefit for the rest of their life, delay frequently wins on household terms even when it loses on early-claim capital terms.

Longevity insurance. If the client lives to 95, the bigger lifetime check earns its keep. Path A's monthly advantage compounds the other direction over a long life.

Tax interactions. Path B layers more taxable Social Security income into earlier years, which can compress Roth conversion windows, push MAGI into IRMAA territory, and complicate withdrawal sequencing. (More on that in the next two drops.)

This is exactly why HNW Social Security planning is a planning conversation, not a filing decision. Both paths can be defensible. Neither is automatic.

The work is in showing the household what each path actually buys — and what it costs.

The advisor takeaway

The better question is not "When should this client claim?"

The better question is: What does this household give up by waiting, and is that trade-off the right one for this plan?

If the answer is delay, that's a recommendation grounded in analysis. The larger check is real. The longevity protection is real. The survivor benefit reinforcement is real.

But if the answer is delay because that's what serious advisors say — the number on the table is bigger than the number on the page.

$220,000 is not a small number to leave unnamed.

The shadow is real. Price it.
