The 4% rule (Bengen, 1994) was revolutionary for its time. It was also built on data from 1926–1992, when bond yields were structurally higher and valuations were lower on average.
In 2026, with starting valuations near all-time highs and bond yields still compressed, blindly using 4% is no longer prudent for most people.
Used by 68% of EarlyFIRE members who retired 2022–2025.
Set a conservative base (3.0–3.25%) + bonus withdrawals when markets perform well.
Time-based buckets with dynamic rebalancing.
| Framework | Success Rate | Best For |
|---|---|---|
| Classic 4% Rule | 65–75% | Simple plans |
| Variable % with Guardrails | 92–96% | Most retirees |
| Floor + Upside | 88–93% | Conservative + growth |
Recommendation: Most EarlyFIRE members now use Framework 1 (Variable % with Guardrails) as their primary method.
