- Those with no other income sources
- 40+ year retirement horizons
The classic “4% rule” amount

- Traditional 30-year retirement
- Diversified portfolios
- Those comfortable with some volatility
- Flexibility to adjust spending
Lower investment, higher risk
Best for:
- Those with other income sources

Quick example #
Target: $3,000/month passive income
| SWR Rate | Investment Needed | Risk Level |
|---|---|---|
| 3% | $1,200,000 | Conservative |
| 4% | $900,000 | Standard |
| 5% | $720,000 | Aggressive |
The difference between conservative and aggressive is $480,000. That’s why understanding your risk tolerance matters.
Tips for best results #
Key considerations:
- Start conservative — If retiring early (before 50), lean toward 3-3.5% SWR
- Include taxes — Your withdrawal may need to be higher depending on your country’s tax rules
- Check multiple scenarios — Look at both “minimum viable” and “comfortable” income levels
- Revisit annually — Recalculate as your expenses and goals change
