Understanding Retirement Planning
Retirement planning is about calculating how much money you need to save to live comfortably after you stop working. It accounts for inflation, investment returns, and your desired lifestyle. The key is starting early - compound interest becomes your best friend when you have 20+ years to save.
Start Early Advantage
Time is your biggest asset. Starting retirement saving 10 years earlier can reduce required monthly contribution by 50%+ due to compound interest working longer.
Inflation Impact
Inflation erodes purchasing power. Your ₹1L today becomes ₹50K in real value over 14 years at 5% inflation. Retirement corpus must account for this rising expense.
4% Withdrawal Rule
You can safely withdraw 4% of corpus annually. If you need ₹3L/year, save ₹75L corpus. This ensures money lasts 30+ years without running out.
Regular Progress Review
Track progress annually. Adjust contributions if needed, increase with salary, and rebalance portfolio as you approach retirement for risk reduction.
Retirement Corpus Calculation Components
| Component | Description | Calculation |
|---|---|---|
| Monthly Expenses | Your planned monthly spending in today's rupees | Input value directly |
| Inflation Adjustment | Rising costs over years to retirement | Expenses × (1 + inflation rate)^years |
| Annual Needs | Monthly expenses × 12 months | Monthly × 12 |
| 4% Rule | Safe withdrawal rate from corpus | Required Corpus = Annual Needs ÷ 0.04 |
| Corpus Growth | Investment returns over accumulation period | Savings × (1 + return rate)^years |
Real-World Retirement Examples
Example 1: Early Planner (Age 30)
Scenario: Start early, benefit from 30 years of compounding
Details: Age 30 → 60, ₹0 current savings, ₹15K/month contribution, 10% return, 5% inflation, ₹50K monthly expenses
Required Corpus: ₹1.85 Cr (inflation-adjusted)
Expected Corpus: ₹2.10 Cr → On Track! Your ₹54L contributions become ₹2.10 Cr due to compound interest.
Example 2: Mid-Career Saver (Age 40)
Scenario: Start late, need higher contributions
Details: Age 40 → 60, ₹25L current savings, ₹30K/month contribution, 10% return, 5% inflation, ₹60K monthly expenses
Required Corpus: ₹3.12 Cr (inflation-adjusted)
Expected Corpus: ₹2.95 Cr → Close but Short! May need to increase contributions or work 2-3 more years.
Example 3: Late Starter Impact Comparison
| Starting Age | Years to Retirement | Monthly Contribution (₹K) | Retirement at 60 | Status |
|---|---|---|---|---|
| Age 25 | 35 years | ₹10K | ₹1.50 Cr | ✅ Comfortable |
| Age 30 | 30 years | ₹15K | ₹1.60 Cr | ✅ On Track |
| Age 35 | 25 years | ₹25K | ₹1.55 Cr | ⚠️ Tight |
| Key: Starting 10 years later requires 2.5x monthly contribution for similar corpus! | ||||
Time is money - starting early dramatically reduces the burden of saving for retirement.
Retirement Corpus Formula
Key Formulas:
1. Required Corpus (4% Rule):
Required Corpus = Annual Expenses × 25 (or Annual Expenses ÷ 0.04)
2. Inflation-Adjusted Annual Expenses:
Adjusted Expenses = Current Expenses × (1 + inflation rate)^years
3. Expected Corpus (Growth of Savings):
FV = Current Savings × (1 + return)^years + Monthly Contribution × [((1 + r)^n - 1) / r] × (1 + r)
Step-by-Step Example:
Problem: Age 35, want to retire at 60. ₹10L saved, ₹20K/month contribution, 10% return, 5% inflation, ₹50K monthly expenses needed. Calculate retirement corpus needed and expected corpus.
Step 1: Years to retirement = 60 - 35 = 25 years
Step 2: Calculate inflation-adjusted annual expenses
- Current monthly = ₹50K
- Current annual = ₹50K × 12 = ₹6L
- Inflation-adjusted = ₹6L × (1.05)^25 = ₹20.48L per year
Step 3: Calculate required corpus using 4% rule
- Required Corpus = ₹20.48L ÷ 0.04 = ₹5.12 Cr
Step 4: Calculate expected corpus from savings + contributions growth → Compare with required corpus to determine if on track
