Question 1

What is a lumpsum investment?

Accepted Answer

A lumpsum investment is a one-time deposit of a fixed amount into an instrument such as a mutual fund, rather than investing gradually over time. The entire amount is invested at once and grows through compounding until maturity.

Question 2

How is lumpsum maturity value calculated?

Accepted Answer

Lumpsum maturity uses the future-value formula: FV = P × (1 + r)^t, where P is the initial investment, r is the expected annual return (as a decimal), and t is the investment period in years. Estimated returns = FV − P.

Question 3

What is the difference between lumpsum and SIP?

Accepted Answer

A lumpsum invests the whole amount at once, while a SIP (Systematic Investment Plan) invests a fixed amount at regular intervals. Lumpsum benefits fully from compounding over the entire period and tends to do better in steadily rising markets, whereas a SIP averages the purchase cost over time (rupee cost averaging) and reduces the impact of market volatility.

Question 4

Why does the calculator show CAGR equal to the expected return?

Accepted Answer

For a lumpsum growing at a constant annual rate, the Compound Annual Growth Rate (CAGR) is mathematically identical to the expected annual return: CAGR = (FV/P)^(1/t) − 1 = r. It is shown separately for clarity and to compare with market-linked, variable-return scenarios.

Question 5

Can a lumpsum investment show a loss?

Accepted Answer

Yes. If you enter a negative expected annual return, the calculator projects a loss — for example, a −10% annual return shrinks the investment each year. At −100% the entire investment is lost. Market-linked investments carry risk, and past performance is not indicative of future results.
