Can I retire at 50 with $750,000 as a single person?

Retiring as a single person at 50 with $750,000 is a 50-year planning problem — possibly the longest single financial decision you'll ever make. The math is dominated by one variable: sequence-of-returns risk in the first decade of withdrawals. Get hit by a 2008-style drawdown in your first three years and your worst-case path looks materially different from someone retiring into a calm decade.

The four levers, in priority order

Spending. The classic Bengen 4% rule on $750,000 gives you $2,500/mo of inflation-indexed portfolio withdrawal. Layered with Social Security at FRA, that's enough to fund a household spending plan around $7,000/mo for most retirees. Households at this savings tier typically have meaningful flexibility — what kills the plan is silent lifestyle drift in the first five years of retirement.

Asset allocation. At 50, a 70/30 or 80/20 stocks/bonds tilt is defensible — the horizon is long enough to ride out almost any historical drawdown, and the variance reduction from a heavy bond allocation costs more in expected return than it gains in downside protection. The risk you're managing isn't market volatility; it's behavioral: a steep early drawdown plus panic selling has wrecked more retirement plans than poor allocation alone.

Social Security. You're 17 years from full retirement age — long enough that your household-income trajectory between now and 67 affects your eventual benefit (top 35 indexed earning years rule). For a single retiree at 50, the breakeven against delaying to 70 lands around age 82; if family longevity history is below average, claiming at 62 is mathematically defensible.

Common pitfall: single retirees consistently underestimate healthcare cost variance. Long-term care alone has a median lifetime cost around $172,000 (Genworth, 2025) and roughly 1-in-3 single retirees will need it for over a year. Yearfold's calculator doesn't model LTC explicitly — set aside ~$200K-$400K outside the simulated portfolio if you're self-funding that risk.

Why a single number isn’t an answer

A bank calculator might tell you “Yes, you can retire — your $750,000 will last.” A Monte Carlo simulation tells you the share of plausible futures in which it lasts, the share in which it doesn’t, and what specifically goes wrong in the failure cases. The 10–25% of paths that don’t work are the part you’d actually want to defend against — by trimming spending, raising allocation, delaying Social Security, or working a couple of years longer.
