What's the best retirement withdrawal strategy?

There is no single best strategy. Most real retirement plans combine multiple frameworks: Social Security and pensions as a guaranteed floor, a 3.5-4% safe withdrawal rate on the portfolio for upside, and sometimes late-life annuitization for longevity protection. The right mix depends on your portfolio size, time horizon, income flexibility, and risk tolerance.

What's the difference between the 4% rule and the Trinity Study?

Bengen (1994) found that 4.15% was safe for 30-year retirements using a 50/50 US stock/bond portfolio. The Trinity Study (1998) extended this across multiple allocations and horizons, confirming 95–100% success rates for 4% withdrawals over 30 years. Same math, different presentations. Both assume US data and 30-year horizons.

What's the fastest way to calculate my FIRE number?

Multiply your annual expenses by 25 (for a 30-year retirement) or 30 (for a 40+ year early retirement). If you spend $50,000/year, you need roughly $1.25-1.5M. This is the 25× rule, the inverse of the 4% withdrawal rate. Run detailed scenarios in our FIRE Calculator.

How do I access retirement funds before 59½?

Three main strategies: (1) Rule of 55 — access current employer's 401(k) penalty-free starting at 55, (2) 72(t) SEPP — equal periodic payments from IRA at any age (5-year commitment), (3) Roth Conversion Ladder — convert traditional IRA to Roth over 5 years, then withdraw converted amounts tax-free. Most early retirees use the Roth ladder.
