SIP Comparison: ₹50,000 Monthly For 15 Years vs ₹15,000 Monthly For 25 Years; Which Will Give You Higher Corpus

A simple way to understand the power of compounding is to place two SIP paths side by side. One commits a larger amount for a shorter period. The other commits a smaller amount for a longer period. Both assume 12% annualised returns. What A SIP Is and Why 12% Matters

A Systematic Investment Plan or SIP spreads contributions across time. The assumed 12% annualised return is a simple working figure used for illustration. Actual returns vary across funds and market cycles.

Case 1: ₹50,000 Monthly SIP For 15 Years At 12%

• SIP Amount: ₹50,000
• Estimated Returns: 12%
• No of Years: 15
• Total corpus after 15 years: ₹ 2,52,28,800
• Total amount invested: ₹ 90,00,000
• Estimated gains: ₹ 1,62,28,800

This path relies on a higher monthly outflow. The corpus grows well, but the time in the market is limited to 15 years.

Case 2: ₹15,000 Monthly SIP For 25 Years At 12%

• SIP Amount: ₹15,000
• Estimated Returns: 12%
• No of Years: 25
• Total corpus after 25 years: ₹ 2,84,64,526
• Total amount invested: ₹ 45,00,000
• Estimated gains: ₹ 2,39,64,526

This path uses a smaller monthly outflow over a longer tenure. The extended compounding window does more of the heavy lifting.

You can do the calculation using SIP Calculator. 

Corpus Comparison And Key Numbers

• Final corpus difference in favour of the longer tenure path: about ₹ 32,35,726
• Total investment outlay is lower in the longer tenure path by ₹ 45,00,000
• Estimated gains difference in favour of the longer tenure path: about ₹ 77,35,726

The longer runway allows compounding to amplify gains even when the monthly contribution is smaller. More periods mean more growth cycles at 12%.

Time In Market vs Size Of SIP

Amount and tenure both matter. A larger contribution speeds up corpus building. A longer tenure lets returns compound through more cycles. When the assumed return is the same, extra years often tip the scales.

Practical Reading Of These Results

• A higher monthly SIP for a shorter duration produces a strong corpus, but the investment burden is heavy.
• A modest monthly SIP for a longer duration can surpass the corpus of the larger SIP, with a lower total amount invested.
• The effect is driven by compounding at 12% across many more periods.
