For years, conventional wisdom has suggested that you need at least 25–33 times your annual expenses as a retirement corpus to live comfortably for 25–30 years post-retirement. But new research and withdrawal strategies challenge this idea, showing that you may not need as much as previously thought.
The Traditional Rule Of Thumb
The old-school retirement model assumes:
- Withdrawals increase annually to match inflation
- A fixed percentage (commonly 4%–4.5%) is withdrawn from the corpus each year
- A balanced portfolio of equity and debt (50:50) sustains growth
By this calculation, retirees are advised to aim for ~33x annual expenses. For example, if you expect ₹15 lakh annual expenses post-retirement, the traditional model demands a corpus of about ₹4.65 crore.
But here’s the problem:
- It assumes inflation-adjusted withdrawals every single year.
- It ignores market cycles, downturns, and periods where a pause in withdrawals may be more sustainable.
- It risks over-saving and delaying retirement unnecessarily.
Alternative Withdrawal Strategies
1. Bengen’s Floor-and-Ceiling Strategy
- Withdrawals stay fixed after the first year.
- Adjustments are capped: never increase more than 20%, never fall below 15%.
- Provides a balance between inflation protection and capital preservation.
💡 Corpus required: ~27x expenses (~₹4.05 crore)
✅ Upside: Withdrawal volatility is controlled.
✅ Downside: Requires discipline and flexibility in spending.
2. Forego Inflation Strategy
- If portfolio returns are negative, skip the inflation-linked increase for that year.
- Resume inflation hikes when markets recover.
💡 Corpus required: ~21x expenses (~₹3.15 crore)
✅ Upside: Needs the lowest corpus, making retirement more achievable.
❌ Downside: Higher volatility in withdrawals, potential lifestyle adjustments.
Case Study: Retiree In 1994 With ₹1 Crore Corpus
A simulation for a 30-year retirement period (1994–2024) showed:
- Traditional model: Corpus depleted before the period ended.
- Forego inflation model: Corpus survived but with some spending dips.
- Bengen’s strategy: Withdrawals remained smoothest, preserving balance between lifestyle and capital longevity.
This demonstrates that strategy matters as much as corpus size.

Key Insights For Indian Retirees
- Flexibility beats rigidity – Retirement is not a straight line. A fixed “inflation + X% withdrawal” isn’t always realistic.
- Smaller corpus is feasible – With smart withdrawal rules, even 21–27x annual expenses can work.
- Lifestyle alignment is key – Be ready to adjust spending during downturns, instead of blindly increasing withdrawals.
- Equity allocation is essential – Pure debt portfolios will struggle against inflation. Balanced equity-debt helps sustain growth.
- Personalization matters – Medical costs, family support, longevity, and risk appetite vary. A one-size-fits-all number doesn’t work.
FAQ – Can You Retire With Less Corpus?
1. What is retirement corpus?
It’s the total savings/investments you build to fund your life after retirement.
2. Can I retire with a smaller corpus?
Yes, if you manage lifestyle, expenses, and investments wisely.
3. What factors decide how much I need?
Lifestyle, inflation, healthcare, life expectancy, income sources, and debts.
4. How can I reduce the required corpus?
Cut expenses, delay retirement, invest smartly, create passive income, or move to lower-cost locations.
5. What strategies work best in India?
Diversify investments, use schemes like PF/NPS, get health insurance, and review plans regularly.
6. When should I start planning?
The earlier, the better—ideally in your 20s or 30s.
7. How often should I review my plan?
At least once a year or after major life changes.
Final Word
You may not need 33x annual expenses to retire securely. With strategies like Bengen’s floor-and-ceiling or forego inflation adjustments, retirees can start earlier, with smaller corpus targets, while still enjoying stability.
The key is discipline, flexibility, and smart asset allocation.
So, instead of waiting forever to hit a “magic corpus number,” ask yourself:
👉 Am I ready to manage my withdrawals smartly?
That’s the real secret to sustainable retirement.
