Can you retire at 45 with $500k?

With $500k at age 45, you can safely spend about $18,000/year after tax ($1,500/month) without running out over a ~50-year retirement — roughly a 3.6% withdrawal rate, below the classic 4% rule — a longer horizon needs a more conservative rate. Whether that's enough comes down to your lifestyle; here's the full picture.

How long $500k lasts at different spending levels

The 4% rule is a starting point, not a guarantee — especially retiring at 45, when the money may need to last 50+ years. Here's what $500k supports, spending from age 45 to 95 at a 6% nominal return and 3% inflation:

Why the answer isn't just $500k × 4%

A back-of-envelope "$500k × 4% = $20,000" overstates what you can safely spend at 45, 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 ($18,000) sits below the headline 4% draw.
• A long horizon. Retiring at 45 can mean 50+ years in retirement. The 4% rule was calibrated to about 30 years — stretch it further and a lower rate (nearer 3.6% here) is what actually survives a bad early market.

The portfolio, year by year

Spending the sustainable $18,000/yr from $500k at age 45, 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.

At 45, think Coast FIRE rather than full stop

Retiring completely at 45 on this amount is a genuine stretch, and it is worth being honest about why: the horizon is long, and there is no Social Security and no Medicare for roughly two decades. That does not mean the number is useless. It means the goal shifts from never working again to never needing to work full time again.

The realistic version usually looks like Coast or Barista FIRE. If part-time or seasonal income covers even a modest slice of spending in the early years, the portfolio can keep growing instead of being drained at its most vulnerable moment. Two other levers do most of the heavy lifting:

• A much lower fixed-cost base, especially paid-off or low-cost housing, or relocating somewhere cheaper.
• A deliberate plan for health coverage before 65, typically through the ACA marketplace, where subsidies scale with modest income.

Frame it as a set of conditions that would need to be true, then test them here. The engine shows how much lighter part-time income and lower spending make the load across a 45-year horizon.
