15-Year Wealth Creation Illustration

Problem: An investor plans to build a dividend growth portfolio using a disciplined long-term approach.

He starts with a monthly investment of ₹20,000 in a diversified portfolio of high-quality dividend-paying stocks.

Every year, he increases his monthly investment by 10% to match income growth.

The portfolio is expected to generate a long-term average return of 12% per annum.

After 15 years, estimate:

1.     The total amount invested

2.     The future value of the portfolio

3.     The annual dividend income if the portfolio yields 3% at the end of 15 years.

Let us solve this step-by-step in a simple and logical manner.

Solution:

✅ Given Data

• Monthly SIP (Year 1) = ₹20,000
• Annual Step-Up Rate (g) = 10%
• Annual Portfolio Return (r) = 12%
• Time Period (n) = 15 years
• Dividend Yield at end = 3%

PART 1 – Total Amount Invested

Since SIP increases every year, we calculate year-wise:

Each year investment rises by 10%.

Year	Monthly SIP (₹)	Annual Investment (₹)
1	20,000	2,40,000
2	22,000	2,64,000
3	24,200	2,90,400
4	26,620	3,19,440
5	29,282	3,51,384
6	32,210	3,86,520
7	35,431	4,25,172
8	38,974	4,67,688
9	42,871	5,14,452
10	47,158	5,65,896
11	51,874	6,22,488
12	57,061	6,84,732
13	62,767	7,53,204
14	69,044	8,28,528
15	75,948	9,11,376

🔹 Total Invested

Sum of all annual investments:

Total Invested ≈ ₹65,25,000 ≈ ₹65 lakh

PART 2 – Future Value of Step-Up SIP

We use Future Value of Growing Annuity Formula:

FV= [P× (1+r) ⁿ−(1+g) ^n​]/ (r−g)

Where:

• P = First year annual investment = ₹2,40,000
• r = 12% = 0.12
• g = 10% = 0.10
• n = 15

Plug Values

FV=2,40,000× [(1.12)¹⁵−(1.10)^15​]/(0.12-0.10)

FV=2,40,000× (5.47−4.18)/0.02

FV = 2,40,000x1.29/0.02

V=2,40,000×64.5

FV≈₹1,54,80,000

🔹 Portfolio Value

Allowing rounding and market variation:

Portfolio Value ≈₹1.4 – ₹1.5

PART 3 – Annual Dividend Income

Dividend=Portfolio Value × Dividend Yield

Dividend Yield = 3%

Dividend Income = Portfolio Value x 3%

If portfolio value = ₹1.45 crore:

1,45,00,000 x0.03 = ₹4,35,000

✅ FINAL ANSWER

Item		Result
Total Invested		≈ ₹65 lakh
Portfolio Value After 15 Years		≈ ₹1.4 – ₹1.5 crore
Annual Dividend Income		≈ ₹4 – ₹5 lakh

 

Monthly Income= ₹33,000-₹42,000

Bonus: If Dividends Grow at 8%

After 5 more years:

4.35 lakh× (1.08)⁵

4.35×1.47=₹6.39 lakh

Without adding new money, income crosses ₹6 lakh/year.

Key Insight

You invested only ₹65 lakh,
but time + compounding + step-up + dividend growth created:

👉 ₹1.5 crore wealth
👉 Lifelong rising income

Interpretation

• Only ₹20,000 per month growing gradually
• Creates crore-level wealth
• Generates lifetime passive income

This is the power of step-up SIP + compounding + dividend growth.

Learning Objective

This problem demonstrates how step-up investing combined with compounding returns can create a large retirement corpus and sustainable income without relying on speculation or market timing.
