How the lumpsum calculator works

A lumpsum investment is a single, one-time deposit of capital into a fund or asset. It is ideal for investing a windfall, inheritance, or bonus. This calculator assumes annual compound interest, showing you how a single lump sum grows over your chosen investment horizon without any additional monthly contributions.

How to Use: 1. Input the "Total investment" principal amount you wish to grow. 2. Specify your expected "Annual return rate". 3. Set the "Time period" in years. All calculations update dynamically as you drag the sliders.

Understanding the Results: The "Projected value" indicates your final maturity amount. The difference between this final value and your original principal represents the "Est. returns" (net interest growth). Use this tool to compare one-time investing gains against systematic monthly plans.

The formula

FV = P × (1 + r)^t

  • P: the amount invested once
  • r: the annual return as a decimal
  • t: the number of years

Growth is compounded once a year.

A worked example

Investing ₹1,00,000 once for 10 years at 12% a year grows to about ₹3,10,585: ₹2,10,585 of growth on what you put in.

Questions people ask

How is the future value of a lumpsum calculated?

The amount grows once a year at the annual rate for the number of years you choose: future value = amount × (1 + rate)^years. The difference between that and what you put in is the estimated return.

Is the projected lumpsum value guaranteed?

No. It assumes the same return every year. Market-linked investments rise and fall, so use the result to compare scenarios, not as a promise.

When does a lumpsum make more sense than a SIP?

When the money is already in hand, for example a bonus or a maturing deposit, and you can stay invested through falls. If the money arrives monthly, a SIP is the natural fit.
