Retirement Planner

Retirement planning is mathematically fascinating because it requires you to balance two opposing forces over extremely long time horizons: Wealth Accumulation vs. Wealth Depletion.

During your working years, you are fighting to outpace inflation. If your expenses are ₹50,000/month today, and inflation is 6%, those exact same expenses will cost over ₹1.6 Lakhs/month in 20 years. Your investments must grow significantly faster than this inflation rate to actually build a surplus corpus.

The hardest math in retirement isn't hitting your target number; it's surviving Phase 2. Once you retire, you stop adding new money to the pile, but inflation keeps going.

This creates the need for Inflation-Adjusted Withdrawals. If you retire with ₹5 Crores and withdraw ₹10 Lakhs in Year 1, you cannot just withdraw ₹10 Lakhs in Year 2. Because of 6% inflation, you must withdraw ₹10.6 Lakhs in Year 2, and ₹11.2 Lakhs in Year 3 just to buy the exact same amount of groceries.

If your retirement corpus is invested entirely in safe, low-yielding assets (like a 6% FD) while inflation is also 6%, your Real Return is exactly 0%. Because your withdrawals keep increasing every year while your real return is 0%, you will drain your corpus dangerously fast. This is why modern financial advisors recommend keeping a portion of your retirement corpus in growth assets (like equities) even after you retire.
