Week 11 Day 5: Your Number Is Closer Than You Think

If you need $50,000/year and Social Security provides $20,000/year, you only need your portfolio to cover $30,000/year. That is $30,000 x 25 = $750,000, not $1,250,000. Social Security, pensions, rental income, and other non-portfolio income all reduce the portfolio burden.

Here is how to calculate your personal number more precisely. Start with your estimated annual retirement spending: $X. Subtract Social Security estimate (check ssa.gov for your projected benefit): -$Y. Subtract any pension income: -$Z. Subtract any rental or other passive income: -$W. The remainder ($X - $Y - $Z - $W) is what your portfolio needs to fund. Multiply by 25 for your portfolio target. Example: $60,000 spending - $22,000 Social Security - $0 pension - $5,000 rental income = $33,000 from portfolio. $33,000 x 25 = $825,000. That is dramatically more achievable than $1,500,000. Most retirement calculators do not personalize this way, which is why generic '80% income replacement' numbers feel so overwhelming. When you account for your specific income sources and actual spending, the target often drops by 30-50%.

Social Security's role in retirement funding cannot be overstated. For retirees in the bottom income quintile, Social Security replaces approximately 82% of pre-retirement income (SSA Office of Research, 2023). For the median earner, it replaces about 40%. For high earners, about 27%. This makes Social Security the most effective anti-poverty program in U.S. history but a relatively small component of high-income retirement planning. The optimal Social Security claiming strategy (ideally delaying until age 70 for an 8% per year increase over the age-62 benefit) can increase lifetime benefits by $100,000-$300,000 for a married couple. This is the highest guaranteed, inflation-adjusted return available anywhere -- 8% per year of delay, guaranteed by the U.S. government. The decision of when to claim Social Security is arguably the most consequential single financial decision most Americans make, yet the majority claim at or before full retirement age, leaving significant money on the table.
