What is a Lumpsum Investment?

A lumpsum investment is a one-time deposit — you put a significant chunk of money into an investment and leave it there to grow. It's the opposite of a SIP, where you invest smaller amounts on a regular schedule. People typically go this route when they've received a bonus, an inheritance, or have been sitting on savings and want to put them to work all at once.

How This Calculator Helps You Project Growth

Enter your initial amount, an expected annual return, and a time period, and you'll see what your investment could look like at maturity. Compounding does the rest.

• The projected maturity value tells you the estimated worth of your investment after the specified period — useful for understanding whether a given opportunity makes sense for your goals.
• The pie chart splits the final amount into your initial investment and the total gain. That visual is often more convincing than the numbers alone — you can see at a glance how much of your ending wealth came from market growth versus your own capital.
• Change the return rate, the time period, or the initial amount and the projection updates instantly. It's a practical way to compare scenarios — say, 10 years versus 15 years, or an 8% return versus a 10% one — without having to pull out a spreadsheet.

Who Can Benefit?

• If you're new to investing, this calculator is a good introduction to what a one-time investment in a mutual fund or fixed deposit might realistically become over time.
• If you've been investing for a while, it's a quick way to compare the potential returns on different opportunities side by side — no spreadsheet required.
• If you work in financial planning, it's a handy tool for showing clients what compounding actually looks like in practice, rather than explaining it in the abstract.
