Retirement planning isn’t just for the 40s or 50s — the earlier you start, the less stress on your future self. The magic comes from compounding interest: your money grows exponentially over time.

Let’s break it down step by step.

1 Set Your Goal: 1 Crore by Retirement

Assume:

  • Retirement age: 60 years
  • Current age: 30 years
  • Goal: ₹1 crore at 60

We’ll calculate how much you need to invest monthly or annually to reach this target.

2 Decide Your Expected Return

Common options for long-term wealth growth:

Investment Type

Expected Annual Return

Mutual Funds (Equity)

12%

Balanced Funds / ETFs

8–10%

Fixed Deposits / Bonds

5–6%

Let’s assume 12% annual return (equity mutual funds), which is reasonable for a 30-year horizon.

3 Use the Compound Interest Formula

Future Value (FV) = P × [(1 + r)^n - 1] / r

Where:

  • P = annual investment
  • r = annual rate of return (decimal)
  • n = number of years

Here:

  • FV = 1,00,00,000
  • r = 12% = 0.12
  • n = 60 − 30 = 30 years

4 Step-by-Step Calculation

FV = 1,00,00,000

P=FV×r(1+r)n−1P = FV \times \frac{r}{(1 + r)^n - 1}P=FV×(1+r)n−1r

(1 + r)^n = (1 + 0.12)^30

Step by step:

  • (1.12)^10 ≈ 3.10585
  • (1.12)^20 = (3.10585)^2 ≈ 9.645
  • (1.12)^30 = (9.645 × 3.10585) ≈ 29.93

(1 + r)^n - 1 = 29.93 − 1 ≈ 28.93

r / ((1 + r)^n − 1) = 0.12 / 28.93 ≈ 0.004146

P = FV × 0.004146 ≈ 1,00,00,000 × 0.004146 ≈ ₹41,460 per year

Annual investment needed: ₹41,500 per year (~₹3,460 per month)

5 Key Takeaways

  • Starting at age 30, you need to invest ~3,500/month at 12% returns to accumulate ₹1 crore by 60.
  • If you start later, the required amount increases drastically. For example, starting at 40 years, you’d need to invest almost 10,000/month to reach the same target.
  • Compounding works best with longer time horizons — even small investments today grow exponentially.

6 Tips for Smart Retirement Planning

Start Early – The earlier you start, the less you need to invest.

Invest in Equity Mutual Funds – Best for long-term growth.

Increase Contributions Over Time – Raise investments by 5–10% yearly with salary growth.

Diversify – Combine equity, debt, and PPF for safety and growth.

Review Annually – Adjust for inflation and returns.
