Can you retire at 55 with $1.5M?

With $1.5M at age 55, you can safely spend about $60,500/year after tax ($5,042/month) without running out over a ~40-year retirement — about a 4.0% withdrawal rate, right around the classic 4% rule of thumb. Whether that's enough comes down to your lifestyle; here's the full picture.

How long $1.5M lasts at different spending levels

The 4% rule is a starting point, not a guarantee — especially retiring at 55, when the money may need to last 40+ years. Here's what $1.5M supports, spending from age 55 to 95 at a 6% nominal return and 3% inflation:

Why the answer isn't just $1.5M × 4%

A back-of-envelope "$1.5M × 4% = $60,000" overstates what you can safely spend at 55, for two reasons this projection captures:

• Taxes. A dollar in a traditional 401(k) or IRA is taxed as ordinary income on the way out; taxable-brokerage gains are taxed too. Only Roth and cash are tax-free. So the safe spendable figure ($60,500) sits below the headline 4% draw.
• A long horizon. Retiring at 55 can mean 40+ years in retirement. The 4% rule was calibrated to about 30 years — stretch it further and a lower rate (nearer 4.0% here) is what actually survives a bad early market.

The portfolio, year by year

Spending the sustainable $60,500/yr from $1.5M at age 55, here's how the portfolio holds up in today's dollars (inflation-adjusted, so it reflects real spending power):

Assumptions: single filer, TX (no state income tax), 60% taxable / 30% traditional / 10% Roth split, 6% nominal return, 3% inflation, no Social Security. Add Social Security, a pension, part-time income, or a spouse in the calculator and the safe number rises — often substantially.

Bridging to Medicare while the conversion window is open

Retiring at 55 opens roughly a ten-year gap before Medicare, and how you fill your taxable income in those years does double duty. Marketplace health-insurance subsidies are keyed to income, so a year heavy with Roth conversions can raise premiums now — while a year kept deliberately low can lower premiums but waste cheap conversion space. The healthcare bridge and the conversion plan have to be solved together, not separately.

Withdrawal order still matters: drawing taxable accounts first, then traditional, then Roth, generally keeps lifetime taxes down and preserves tax-free growth the longest. But at this balance the early years also carry sequence-of-returns risk — a poor market run right after you stop earning can do lasting damage. Holding a cushion of stable assets to spend from during downturns lets equities recover instead of being sold at a loss.

The Rule of 55 gives penalty-free access to your final employer’s 401(k), so the bridge to 59½ need not lean only on taxable savings. Balancing conversions, subsidy thresholds, and sequence risk across these years is where the real optimization lives.
