Is $400,000 Enough to Retire? A Realistic Assessment

2026-03-206 min read

$400K puts you in a more comfortable position than you might think, especially with Social Security. Here is what the numbers show.

What Does the Analysis Show for $400K?

Portfolio income at 4%: $16,000/year. Add Social Security for a couple (average: $42,000/year combined) = $58,000/year total.

Monte Carlo results for a 65-year-old couple: 87% success rate at $55,000/year spending, 92% at $50,000/year. The success rate is driven primarily by Social Security optimization — delaying the higher earner to 70 adds $8,000-$12,000/year in guaranteed income.

At $400K, the portfolio's role is supplemental — filling the gap between SS/pension and spending. This is actually a comfortable position if spending is moderate.

What Are the Key Optimization Strategies at $400K?

1. Delay Social Security: At this portfolio level, SS is the dominant income source. Every year of delay adds 6-8% to that income.

2. Roth conversion window: With a relatively small tax-deferred balance, the conversion window is short — you can convert most of it at 10-12% rates before RMDs begin.

3. Keep housing costs under 30% of income: At $55,000/year, that's $1,375/month. If your mortgage is paid off, you're well within this.

4. Part-time work in early years: $10,000-$15,000/year for 3-5 years reduces portfolio dependence during the critical early period.
