Introduction

Retirement planning answers one core question: How much money will I need to maintain my lifestyle after I stop working? Start early to harness compounding. This guide shows a practical method to estimate required corpus and recommended investment options.

Step 1 — Estimate future monthly expense

  • Current monthly expense: ₹50,000 (example).
  • Assume inflation at 6% p.a. for 25 years (you plan to retire in 25 years).

Future monthly expense calculation:

Future monthly = Current monthly × (1 + inflation)^years

= 50,000 × (1.06)^25 ≈ ₹2,14,594 per month

(Using (1.06)^25 ≈ 4.2919; 50,000 × 4.2919 ≈ 214,594.)

Annual expense at retirement = 214,594 × 12 ≈ ₹25,75,122.

Step 2 — Convert annual expense to required corpus

A common planning heuristic is the 4% safe withdrawal rule (withdraw 4% of corpus per year to sustain for 30+ years). Corpus = Annual expense / 0.04.

Corpus = 25,75,122 / 0.04 ≈ ₹6,43,78,061 ≈ ₹6.44 crore

This is a guideline. Use different withdrawal rates (3.5% for conservative, 4.5% for aggressive) to stress-test your plan.

Step 3 — How to build that corpus

  • Start early: The earlier you start, the lower the monthly SIP required.
  • Asset allocation by age (rule-of-thumb):
    • Early career (20s–30s): Higher equity allocation (70–90%).
    • Mid career (40s–50s): Gradually shift to 50–60% equity.
    • Pre-retirement (last 5–10 years): Increase debt & liquid assets to preserve capital.

Investment vehicles (roles)

  • Equity mutual funds / direct equity: Growth engine.
  • PPF / debt funds / govt bonds: Capital preservation & stability.
  • NPS: Tax-efficient retirement product with annuity options.
  • Emergency fund: 6–12 months expenses in liquid funds/FD.

Example: Monthly SIP needed (rough)

To reach ₹6.44 crore in 25 years at an assumed annual portfolio return of 10% (compounded monthly), you can compute the required monthly SIP using financial calculators.

(A site can host an embeddable SIP calculator with input fields for target corpus, years, and expected return—this is a useful lead magnet.)

Practical tips

  • Rebalance annually.
  • Increase SIPs with salary hikes.
  • Account for health insurance & long-term care.
  • Plan estate & wills—ensure smooth transfer of wealth.
