Retirement Planning Playbook: Building a Lifetime Income

The Foundation: What is Your Retirement Number?

Your 'retirement number' is the corpus you need at retirement to fund your lifestyle without running out of money. The 4% rule (from the Trinity study) says: if you withdraw 4% of your corpus in year 1 and adjust for inflation each year, your money should last 30+ years with very high probability.

Retirement Number = Annual Expenses at Retirement ÷ 4%

Example: If you need ₹1.5 lakh/month at retirement (in today's money), adjust for inflation. At 6% inflation over 20 years:

Future monthly expense = ₹1.5 lakh × (1.06)^20 ≈ ₹4.8 lakh/month Future annual expense = ₹57.6 lakh Retirement Corpus Needed = ₹57.6 lakh ÷ 4% = ₹14.4 crore

NOTE: India-specific note: The 4% rule was derived from US data. Given higher Indian inflation and shorter bond history, a more conservative 3–3.5% withdrawal rate may be prudent, implying 28–33x annual expenses.

The Three Pillars of Retirement Savings

A robust retirement plan uses multiple instruments with different characteristics:

Instrument | Returns | Tax Treatment | Liquidity | Best For

EPF / VPF | 8.25% | Tax-free on withdrawal after 5 yrs | Low (till 58) | Stable fixed returns

PPF | 7.1% | EEE — fully tax-free | Very Low (15 yr lock) | Long-term debt allocation

NPS Tier 1 | 9–12% (equity portfolio) | Partial — 60% tax-free | Very Low (till 60) | Additional ₹50K deduction

Equity MF | 12–15% (historical) | 10% LTCG above ₹1L | High | Wealth creation engine

The Equity Glide Path

A glide path is the gradual reduction of equity exposure as you approach retirement. At 30, you can afford to have 80–90% in equity — market downturns will recover. At 60, a 40% fall in equity just before retirement is devastating. The glide path prevents this.

TIP: Don't go to zero equity at retirement. Inflation will erode purely debt-based retirement portfolios over 20–30 years. Maintain 25–35% equity throughout retirement.

Age | Equity % | Debt/Stable %

30–40 | 80–90% | 10–20%

40–50 | 65–75% | 25–35%

50–55 | 50–60% | 40–50%

55–60 | 35–45% | 55–65%

At retirement | 25–35% | 65–75%

Accumulation Phase: How Much to Save

Here's a simplified SIP target framework to accumulate ₹5 crore by 60 at 12% CAGR:

This illustrates the compound effect of starting early. Every 5-year delay roughly doubles the required monthly investment.

Age at Start | Monthly SIP Needed | Total Investment

25 | ₹8,500 | ₹30.6 lakh over 35 years

30 | ₹15,300 | ₹45.9 lakh over 30 years

35 | ₹27,900 | ₹67 lakh over 25 years

40 | ₹52,500 | ₹94.5 lakh over 20 years

Distribution Phase: Withdrawal Strategy

The withdrawal phase is as important as the accumulation phase. A popular strategy is the Bucket Approach:

**Bucket 1** (2–3 years of expenses): Liquid fund or short-duration FD. This is your immediate spending corpus — insulated from market volatility.

**Bucket 2** (3–7 years of expenses): Short to medium duration debt funds. Replenishes Bucket 1 over time.

**Bucket 3** (remaining corpus): Equity mutual funds. Long-term growth engine. Only withdraw when markets are up; never sell in a crash.

Planning for Healthcare in Retirement

Healthcare is the most underplanned component of retirement. Medical inflation runs at 12–14% per year. Build a separate health reserve:

• Maintain a dedicated health corpus of ₹20–30 lakh in liquid/debt investments, separate from main retirement corpus

• Buy comprehensive health insurance immediately — premiums rise sharply every 5 years after 60

• Super top-up plans (₹50–90 lakh additional cover) are essential for catastrophic illness coverage

• Consider critical illness cover before retirement to cover out-of-pocket expenses that health insurance doesn't cover
