America’s Most Underrated Retirement Move

Every week, someone in their late 50s or early 60s asks: what is the single highest-return thing I can do to make my retirement work? They expect the answer to be a location, a Roth conversion schedule, or a clever annuity. It is almost never any of those. The most underrated retirement move in America is deciding when to turn on Social Security, and specifically, using portfolio dollars to buy your way to age 70. It is boring, unglamorous, and quietly outperforms most moves people spend years agonizing over.

The 8% Coupon Almost Nobody Buys

Here is the mechanic. Claim at 62, and your benefit is cut by up to 30% versus your full retirement age amount. Wait past full retirement age, and for each year you don’t draw on benefits up to age 70, your checks go up by about 8%. That increase is locked in for life, adjusted every year by the COLA, which for 2026 came in at 2.8%. No annuity on the market offers a real, inflation-linked, government-backed 8% simple annual increase on a joint-life payout. It exists only inside Social Security, and the only way to buy it is to not claim.

The reason so few people take it is behavioral. Waiting feels like leaving money on the table, especially when headlines constantly remind you that in 2033, our spending will still be increasing, our income will continue to fall, and our surplus will be gone. That headline risk is real, but it does not change the math on delay for anyone with average or better longevity. Reduced payouts, if they ever materialize, would apply to claimants and delayers alike.

What the Bridge Actually Costs

Take a couple retiring at 65 with a target of $95,000 a year in current dollars, roughly consistent with the services-heavy spending pattern the BEA reports, where housing and healthcare alone account for 34.8% of total spending. Assume their combined benefit at full retirement age would be $58,000, and delaying to 70 pushes it toward roughly $77,000. Medicare handles the healthcare bridge, so no ACA subsidy game to play.

The bridge to 70 requires five years of self-funded spending at $95,000, or about $475,000 in nominal outlays, before Social Security turns on. A five-year Treasury ladder built today yields 4.41%, which more than covers the Core PCE running around 130.08 on the index, comfortably above the Fed’s 2% target but stable enough to plan around. A dedicated bridge sleeve of roughly $450,000 in short-to-intermediate Treasuries covers the entire gap without touching equities.

Once age 70 hits, that $77,000 in permanent income means the portfolio only has to fund the remaining $18,000 gap in current dollars. At a 4% withdrawal rate, that gap requires $450,000. Add the depleted bridge sleeve back in as if it were still there, and the couple’s total portfolio target lands near $900,000 to fully support the plan. Delay collapses the number they need to have saved.

The RMD Side Door Most Planners Skip

The move most articles miss is what happens to the tax-deferred account during the bridge years. Spending down the 401(k) between 65 and 70 shrinks the balance that RMDs will eventually be calculated on. Every dollar pulled at, say, a 12% or 22% marginal bracket during the bridge is a dollar that never gets pushed into a higher bracket later, when combined RMDs, the full $77,000 Social Security check, and IRMAA thresholds pile on top of each other. This is the same problem Robert, who is past 70.5 years old, asks what to do with required minimum distributions from his three retirement accounts since he doesn’t need the money to live on. The bridge years are the cheapest tax window a retiree ever gets, and delaying Social Security is what creates it. Layering Roth conversions on top, up to the top of the 12% bracket, turns the bridge into a lifetime tax reduction alongside income optimization.

What It Actually Takes

The number that supports this plan for a couple targeting $95,000 in current dollars is roughly $900,000 by age 65, split into a five-year Treasury bridge of about $450,000 and a growth-oriented sleeve of roughly the same size withdrawing at 4% once Social Security kicks in at 70. It assumes a modest 4% to 4.5% real return on the growth sleeve, a 2.8% COLA continuing on benefits, and the discipline to actually leave the claim alone through your 60s while the market does whatever it does. The move is the patience, not the portfolio composition. That is why almost nobody makes it, and why it remains the most underrated decision in American retirement planning.
