What this calculator helps you understand

A lumpsum calculator shows the effect of compounding on a one-time investment. It is useful for comparing a single investment with different return assumptions and time horizons.

How to use it

  1. Enter the amount invested today.
  2. Enter an assumed annual return.
  3. Choose how long the money remains invested.
  4. Compare the effect of a longer time horizon.
Important: Market-linked investments do not guarantee the assumed return. Actual outcomes can be higher or lower.

Frequently asked questions

What is a lumpsum investment?

It is a one-time investment rather than a series of periodic contributions.

Does this include taxes and fees?

No. Taxes, expense ratios, transaction costs and other charges can reduce actual returns.

Why does time matter so much?

Compounding gives earlier returns more time to potentially generate additional returns.
