A SIP calculator can make long term financial planning easier to understand. It shows how time, monthly contribution, and compounding work together.
When the target is a ₹2 crore corpus by the age of 60, the age at which an investor begins plays a major role in deciding the monthly SIP amount required.
When an investor starts at the age of 30, they have 30 years to build the target corpus. This gives the investment a long runway to grow.
Details of the scenario:
Monthly SIP amount: ₹5,670
Investment period: 30 years
Estimated return: 12% annualised
Total corpus at 60: ₹2,00,14,611
Total invested amount: ₹20,41,200
Estimated returns: ₹1,79,73,411
This example shows the strength of time in wealth creation. The invested amount is relatively modest, yet the final corpus crosses ₹2 crore because the money remains invested for three decades. A large part of the final value comes from estimated returns rather than the actual capital invested.
When the starting age shifts to 40, the investment period falls to 20 years. As a result, the monthly SIP requirement rises significantly.
Details of the scenario:
Monthly SIP amount: ₹20,050
Investment period: 20 years
Estimated return: 12% annualised
Total corpus at 60: ₹2,00,32,916
Total invested amount: ₹48,12,000
Estimated returns: ₹1,52,20,916
This scenario highlights how a 10-year delay changes the picture. Even though the target remains the same, the required monthly investment rises by more than three times compared to the first case. The investor still benefits from compounding, but the shorter duration reduces its overall impact.
Starting at 50 leaves only 10 years to build the same ₹2 crore corpus by 60. This puts far more pressure on the monthly contribution.
Details of the scenario:
Monthly SIP amount: ₹86,090
Investment period: 10 years
Estimated return: 12% annualised
Total corpus at 60: ₹2,00,02,071
Total invested amount: ₹1,03,30,800
Estimated returns: ₹96,71,271
This case makes the effect of delay very clear. The required monthly SIP becomes extremely high because there is much less time for growth. The invested amount itself crosses ₹1 crore, while the estimated returns contribute a comparatively smaller share than in the earlier scenarios.

A side by side comparison makes the difference even more striking.
At 30, the required SIP is ₹5,670 per month.
At 40, the required SIP rises to ₹20,050 per month.
At 50, the required SIP jumps to ₹86,090 per month.
A SIP calculator helps investors estimate how much they need to invest every month to reach a financial target within a fixed time period. In this case, the goal is to accumulate a corpus of ₹2 crore by the age of 60.
The numbers clearly show one simple truth. The earlier a person starts, the lower the monthly burden tends to be. This happens because investments made earlier get more time to grow through compounding. On the other hand, delaying the start means the investor has fewer years, which increases the monthly SIP required quite sharply.
Many people assume that a short delay may not make a big difference, but this comparison shows otherwise. Waiting from 30 to 40 increases the monthly SIP requirement sharply. Waiting until 50 makes the amount even more demanding.
This SIP calculator based comparison of starting at 30, 40, and 50 shows how age can influence the monthly SIP needed to build a ₹2 crore corpus by 60. With a 30-year horizon, the required SIP is far lower, and compounding does much of the heavy lifting. With 20 years, the monthly amount rises substantially. With only 10 years left, the required SIP becomes very high.
