Lumpsum vs SIP and how compounding works

A lumpsum investment is a single, one-time deposit, while a SIP (Systematic Investment Plan) spreads smaller amounts across many months. A lumpsum benefits from the full power of compounding from day one because the entire amount is invested upfront. The growth follows FV = P × (1 + r/100)years, where P is the amount you invest, r is the expected annual return as a percentage, and years is how long you stay invested. Because each year’s returns are added back and earn returns themselves, the curve gets steeper over time — this is why staying invested longer matters so much.

For example, ₹1,00,000 invested at a 12% annual return for 10 years grows to roughly ₹3,10,585, of which about ₹2,10,585 is the gain. Equity returns are not fixed, so use the calculator to compare optimistic and conservative rates rather than relying on a single number. The figures here are estimates to help you plan and are not a guarantee of future returns.

Frequently asked questions

What is a lumpsum investment?
A lumpsum investment is a single, one-time amount you invest all at once, instead of spreading it over many months. The whole amount starts compounding from day one, which is why lumpsum works best when you have a large sum ready to invest for the long term.
How is the future value of a lumpsum calculated?
The calculator uses the compound growth formula FV equals P times (1 plus r divided by 100) raised to the number of years, where P is your investment, r is the expected annual return and years is how long you stay invested. Returns are simply the future value minus the amount you invested.
Is lumpsum better than SIP?
Neither is always better. A lumpsum can earn more when markets rise steadily because the full amount is invested upfront, while a SIP averages your cost and reduces timing risk in volatile markets. Many investors use a lumpsum when they have a large sum ready and a SIP for regular monthly savings.
Are the returns shown guaranteed?
No. The returns are estimates based on the annual rate you enter. Actual mutual fund and equity returns vary year to year and are not guaranteed, so treat the result as a planning guide rather than a promise.
Is my data stored anywhere?
No. The entire calculation runs locally in your browser. Your investment amount and other details are never uploaded to any server.
