The Mathematics of Retirement: The 4% Rule & Capital Preservation
A globally respected retirement benchmark is the 4% Safe Withdrawal Rule (derived from the Trinity Study), which states that withdrawing 4% of your starting retirement portfolio in Year 1 (adjusted for inflation thereafter) gives you a 95%+ probability of never running out of money over a 30-year retirement.

Structuring a Multi-Tier Retirement Income Bucket Strategy
To balance liquidity, stable monthly income, and capital growth during retirement, financial planners recommend the 3-Bucket Strategy:
- Bucket 1 (Immediate Cash - Years 1 to 3): Liquid funds, bank FDs, and short-term debt instruments covering 3 years of living expenses to avoid selling equities during market downturns.
- Bucket 2 (Income Generation - Years 4 to 10): Corporate bond funds, Post Office Monthly Income Scheme (POMIS), SCSS, and NPS annuity plans generating stable, predictable payouts.
- Bucket 3 (Long-Term Growth - Years 11+): Diversified equity mutual funds, index funds, and blue-chip stocks compounding above inflation to fund the latter half of retirement.
