The future value formula is a basic financial calculation used to determine the future worth of an investment after accounting for compound growth over time. It calculates the growth of an initial principal amount when interest or other gains are periodically added to the original investment. This formula is useful when evaluating a potential lump sum investment, as it allows you to estimate how much that investment could be worth at a future date after earning periodic returns. Read on to understand the concept of lump sum investments and how the future value formula can be your investment planning.

What is lump sum investment?

A lump sum investment refers to putting a large amount of money into an investment all at once, rather than spreading out investments over time. Lump sum investing is the opposite systematic investment plans, where smaller periodic investments are made on a regular schedule. The lump sum could come from an inheritance, sale of assets, accumulated savings, or other windfall source.

What is future value?

Future value is a financial concept that calculates the worth of an investment at a specified time in the future, considering the effects of compound interest. It helps you estimate how much your lump sum investment will grow over time, providing a clearer picture of its potential.

The future value formula:

The formula is



  • FV is the future value of the investment.
  • P is the principal amount (your initial investment).
  • r is the annual interest rate (expressed as a decimal).
  • t is the number of years the money is invested.

Consider you receive a lump sum of Rs 1,00,000 and decide to invest it at an annual interest rate of 8% for 5 years. Using the future value formula,

FV = 1,00,00(1+0.08)5

FV = 1,46,933

This means your initial lump sum could potentially grow by nearly 47% over the 5-year period.
