Week 48 Day 3: The Bridge Strategy: Using Savings to Delay Claiming

Example: You retire at 62 with $800,000 saved. Instead of claiming Social Security immediately ($1,400/month), you withdraw $40,000/year from your portfolio for 8 years ($320,000 total) and claim at 70 ($2,480/month). Your portfolio drops to approximately $600,000 (after some investment growth), but your guaranteed income is $2,480/month instead of $1,400/month -- $12,960/year more, for life, inflation-adjusted. By your mid-80s, the higher Social Security payments have more than repaid the $320,000 you withdrew, and you continue to receive the higher amount for the rest of your life.

The bridge strategy works because you are converting volatile portfolio assets into a guaranteed, inflation-indexed income stream at a highly favorable exchange rate (the 8% delayed retirement credits). The planning considerations: (1) Your portfolio withdrawal during the bridge years should come from cash, bonds, or conservative assets -- not from stocks that might be in a downturn. This is why the 'bond tent' concept (Week 44 Day 5) pairs perfectly with the bridge strategy. (2) The bridge years (62-70) are also prime Roth conversion years. With no Social Security income and potentially no employment income, your tax bracket is likely at its lowest. Converting traditional IRA money to Roth during these years reduces future RMDs and taxes while filling the income gap. (3) Health insurance during the bridge years (before Medicare at 65) is a real cost that must be planned for -- ACA marketplace plans with subsidies are the typical solution. (4) The bridge strategy is most valuable for the higher-earning spouse in a married couple. Even if the lower earner claims at 62, the higher earner's delay to 70 protects the surviving spouse with a larger benefit. Kitces (2013) estimated that the combination of delayed Social Security claiming, Roth conversions during the bridge years, and strategic bond tent allocation can add $100,000-$200,000 in lifetime after-tax retirement income for a typical household.

Pfau (2018) conducted Monte Carlo simulations comparing four strategies for a couple retiring at 62 with $1,000,000 in savings: (1) both claim Social Security at 62, (2) both delay to full retirement age (67), (3) lower earner claims at 62 and higher earner delays to 70, (4) both delay to 70 using portfolio bridge withdrawals. Strategy 4 produced the highest median remaining wealth at age 95 in 78% of simulations, despite the portfolio drawdown during the bridge years. Strategy 3 (the 'split' approach) was optimal in 18% of cases (primarily when early mortality reduced the value of delayed claiming for the lower earner). The counterintuitive finding: even though the portfolio shrinks during the bridge years, the reduced reliance on portfolio withdrawals after age 70 (because Social Security covers a larger share of expenses) allows the portfolio to recover and grow. Blanchett (2020) showed that a retiree who delays to 70 and uses the bridge strategy has a 92% probability of maintaining their lifestyle to age 95, versus 78% for a retiree who claims at 62 and preserves their portfolio. The bridge strategy also pairs with 'tax alpha' opportunities: Mahaney (2012) estimated that strategic Roth conversions during the low-income bridge years generate $50,000-$150,000 in lifetime tax savings for households with $500,000+ in traditional IRA balances, because conversions at the 12% bracket are far cheaper than future RMD-forced withdrawals at 22% or higher.
