๐Ÿง  Understanding Reverse CAGR

๐Ÿ” What is Reverse CAGR? Instead of finding the growth rate, Reverse CAGR calculates the initial investment amount given the final value, growth rate, and time period.

๐Ÿ“š Formula:

Starting Value = Final Value รท (1 + CAGR)n

๐Ÿ“ฆ Inputs:

  • Final Value: The amount you ended up with (e.g., โ‚น2,00,000).
  • CAGR: Annual growth rate as a percentage (e.g., 12% = 0.12).
  • Time Period: Number of years the investment grew.

โœ… Example:

If you have โ‚น2,00,000 after 5 years at a 12% CAGR, the starting value is:

Starting Value = 200000 รท (1 + 0.12)5 โ‰ˆ โ‚น1,13,514.88

Your investment started at approximately โ‚น1,13,514.88! ๐ŸŽ‰

๐Ÿ“ˆ Reverse CAGR Calculator: Uncover the Original Investment Behind Your Wealth

Have you ever tried to calculate how much money you originally invested to achieve your current wealth with a specific growth rate? You've come to the right place. The Reverse CAGR Calculator is your financial tool to crack this very enigma.

Here in this article, we will guide you through:

  • What is a reverse CAGR calculator? ๐Ÿง 
  • How to use it with examples and tables ๐Ÿ“Š
  • A real-life case study ๐ŸŒŸ
  • Why it's important for investors ๐Ÿ’ก
  • And a simple way to do it at no cost ๐ŸŽ‰

Let's begin.

๐Ÿ” What is a Reverse CAGR Calculator?

The Reverse CAGR Calculator assists you in determining the original investment amount with:

  • Your ending balance ๐Ÿ’ฐ
  • The CAGR (Compound Annual Growth Rate) ๐Ÿ“ˆ
  • The time period (or years) โณ

It's the reverse of a standard CAGR calculator. Rather than determining how much your investment increased, this tool tells you how much you initially invested to achieve your target.

๐Ÿ“š Reverse CAGR Formula

This is the straightforward yet effective formula that the Reverse CAGR Calculator employs:

Initial Investment = Final Value รท (1 + CAGR)n

Where:

  • Final Value = Ending value of the investment
  • CAGR = Annual growth rate (in decimal, i.e., 10% = 0.10)
  • n = Number of years

๐Ÿ“Š Reverse CAGR Examples Table

Here's a table illustrating how varying final amounts, CAGR percentages, and time frames influence the initial investment:

Final Amount (โ‚น)CAGR (%)YearsInitial Investment (โ‚น)
200,00010%5124,184.98
500,00012%7223,118.80
10,00,0008%104,63,193.70
150,0006%3125,973.78
300,00015%6126,231.06

This allows you to approximate how much you originally had to invest at a specific growth rate to achieve your desired financial objectives.
