What is the 4% Rule and How Does It Work?

5 min read

The 4% rule is a retirement guideline suggesting you can withdraw 4% of your savings in the first year, then adjust for inflation annually, with high likelihood your money lasts 30 years. Developed in 1994 using US data, we'll examine how it applies to Indian investors facing higher inflation and different market conditions. You'll learn when the 4% rule works, when to adjust it, and alternative withdrawal strategies for our economic environment.

Original 4% Rule Mechanics

How it works: ₹5Cr portfolio × 4% = ₹20L first-year withdrawal. Next year: ₹20L + 6% inflation = ₹21.2L. The rule assumes: 1) 50-60% equity portfolio, 2) 30-year retirement, 3) 2-3% inflation (US context). Historical success rate: 95% in US markets. Indian context challenges: 1) Higher inflation (6% vs 3%), 2) More volatile markets, 3) Longer lifespans (plan for 35+ years). Modified 3.5% rule may be safer here: ₹5Cr × 3.5% = ₹17.5L first year. This increases success rate to ~85% for Indian conditions.

When the Rule Fails

The 4% rule struggles during: 1) Early retirement (40+ year horizons need 3-3.5%), 2) High inflation periods (1970s-style 8%+ inflation), 3) Market crashes in first 5 retirement years (sequence risk). Example: Retiring in 2008 with 50% equity would have seen portfolio drop 35% just as withdrawals began. Alternative approaches: 1) Dynamic withdrawals (reduce spending 10% in bad years), 2) Bucket strategy (3 years cash, 5 years bonds, rest equities), 3) Floor-ceiling method (ensure ₹10K/month minimum regardless). For Indian retirees: Combining 4% rule with ₹20-30K/month pension/Senior Citizen Scheme provides safety buffer.

India-Specific Adjustments

1) Healthcare inflation adjustment: Withdraw 4% + 2% extra for medical (6% total first year). 2) Home ownership advantage: Without rent, 4% may suffice. 3) Currency risk: If children abroad, account for exchange rate swings. 4) Cultural factors: Account for family support/gifts. Practical example: ₹6Cr portfolio, ₹24K/month first year (4%). But add: ₹5K for healthcare inflation, subtract ₹8K for no rent = ₹21K sustainable. Better yet: Take 3.5% (₹17.5K) initially, allowing increases later if portfolio grows. Always review withdrawals annually - rigid adherence is riskier than flexible spending.

Key Takeaways

The 4% rule provides a helpful starting point but isn't a set-and-forget solution for Indian retirees. Treat it as a flexible guideline rather than a strict limit - some years take less (market downturns), some years more (medical emergencies). Combine it with guaranteed income sources (pension, rental) for stability. Most importantly, revisit your withdrawal rate annually based on portfolio performance and inflation - this adaptability is key to making your savings last a lifetime.
