Many investors often wonder whether a lumpsum investment or a monthly SIP creates a larger corpus over a long period. A SIP and lumpsum calculator helps understand this difference clearly by showing how investment amount, time and compounding work together.
Both SIP and lumpsum investing are different ways of participating in market linked investments. In a lumpsum investment, the entire amount is invested at one time. In SIP, a fixed amount is invested every month over a chosen period.
For this example, we are looking at a 20-year period with an assumed annualised return of 12%. The aim is only to understand the numbers through a calculator-based approach.
In the 1st scenario, the investor invests ₹10,00,000 as a lumpsum amount for 20 years.
The assumed annualised return is 12%. Based on this, the investment may grow to around ₹96,46,293 after 20 years.
The total invested amount remains ₹10,00,000, while the estimated return comes to around ₹86,46,293. This shows the power of compounding when money stays invested for a long period.
In the 2nd scenario, the investor starts a monthly SIP of ₹20,000 for 20 years.
Over the full period, the total invested amount becomes ₹48,00,000. At an assumed annualised return of 12%, the final value may grow to around ₹1,99,82,958.
The estimated return in this case comes to around ₹1,51,82,958. Since the investor continues adding money every month, the total investment amount is much higher than the lumpsum example.
At first glance, the SIP value looks much larger than the lumpsum value. However, it is important to understand that both examples do not have the same total investment amount.
In the lumpsum case, the investor puts in ₹10,00,000 once. In the SIP case, the investor invests ₹20,000 every month, taking the total contribution to ₹48,00,000 over 20 years.
So, the larger SIP corpus is mainly because the investor contributes more money over time. The calculator helps present this difference in a simple and transparent way.

The lumpsum example highlights how one time investment benefits from staying invested for the entire 20 year period. The SIP example shows how regular monthly investing can build a much larger corpus when contributions continue steadily over time.
Both methods depend on the assumed return, investment period and total amount invested. Actual returns may vary as market linked investments do not move in a straight line.
A SIP and lumpsum calculator is useful for understanding how different investment styles may grow over time. In this example, the lumpsum investment of ₹10,00,000 grows to around ₹96.46 lakh, while a monthly SIP of ₹20,000 grows to around ₹1.99 crore over 20 years at 12% annualised return.
The comparison shows that compounding, time and total contribution all play an important role in wealth creation.
