Future Value Calculator

Estimate the future value of your investment.

What is it?

Future value estimates how much a current lumpsum investment will grow to after a given number of years, based on a fixed expected rate of return and compound interest.

Formula

FV = PV × (1 + r)^t

Formula Explanation

This is the fundamental compound growth formula in finance — a present amount grows by a factor of (1 + rate) for every year it compounds. It's the building block behind most other investment calculators, including SIP, lumpsum, and retirement projections.

Example Calculation

$300,000 invested today at 12% annual return grows to about $931,754 after 10 years — a gain of roughly $630,000.

How to Use

  1. Enter the present value of your investment.
  2. Enter the expected annual interest rate.
  3. Enter the number of years.
  4. View the projected future value and profit earned.

Benefits

  • The simplest, most direct compounding calculation — no monthly contributions to track.
  • Forms the basis for understanding every other compounding calculator on this site.
  • Quick to use for a single "what if I invest X today" question.

Use Cases

  • Projecting the growth of an existing lumpsum investment.
  • Understanding the raw mathematics behind compound growth.
  • Quick sanity checks before running more detailed calculations.

What Your Result Means

The future value is what your present investment is projected to become after the given number of years, assuming the return rate holds steady annually. The profit figure isolates the compounding gain from your original amount.

Tips

  • This is the same math used inside the Lumpsum Investment calculator — use whichever framing matches your question.
  • For monthly contributions instead of a single amount, use the SIP calculator instead.
  • Use a conservative return estimate to avoid overstating your projection.

Common Mistakes

  • Confusing future value (nominal) with real, inflation-adjusted value — pair with the Inflation calculator for that.
  • Using an unrealistically high rate that inflates the projected result.
  • Applying this single-lumpsum formula to a situation involving monthly contributions.

FAQs

What is the difference between future value and present value?

Future value tells you what today's money will grow to in the future; present value works the other way, telling you what a future amount is worth today.

Does this account for inflation?

No, this calculates nominal future value. To estimate real (inflation-adjusted) value, use an inflation-adjusted rate of return instead.

Why does a longer time period increase the future value so much?

Because of compounding — returns are earned not just on the principal but also on previously accumulated growth, which accelerates over time.

Can I use this for monthly compounding instead of yearly?

This calculator compounds annually — for monthly compounding on a lumpsum, use the Compound Interest calculator, which lets you choose the compounding frequency.
