A lumpsum calculator helps explain how a one time investment can grow over a long period when annualised returns are assumed. In this example, the target corpus is ₹5 crore after 30 years, with two return scenarios considered for better understanding.
In the first scenario, the expected annualised return is 12% over a period of 30 years. To reach a corpus of around ₹5 crore, the required lumpsum investment is ₹16,75,000.
The estimated total value after 30 years comes to ₹5,01,82,870. Out of this, the invested amount remains ₹16,75,000, while the estimated return is ₹4,85,07,870.
This shows the power of compounding over a long duration. Even though the initial investment is less than ₹17 lakh, the value grows substantially because the returns are assumed to compound over three decades.
In the second scenario, the expected annualised return is 15% over the same period of 30 years. Here, the required lumpsum investment falls to ₹7,60,000 to reach a corpus of around ₹5 crore.
The estimated total value after 30 years comes to ₹5,03,20,947. The invested amount is ₹7,60,000, while the estimated return is ₹4,95,60,947.
This scenario highlights how a higher assumed return reduces the initial investment required. The difference between 12% and 15% may look small on paper, but over 30 years, the impact becomes meaningful due to compounding.
At 12% annualised return, a lumpsum investment of ₹16,75,000 grows to ₹5,01,82,870 over 30 years.
At 15% annualised return, a lumpsum investment of ₹7,60,000 grows to ₹5,03,20,947 over the same period.
The gap in required investment is large because the assumed rate of return is higher in the second scenario. The longer the investment period, the stronger the effect of compounding becomes.
