percentage growth calculator - Savvy Calculator

Introduction

In today’s fast-paced world, understanding and calculating growth rates are essential in various fields such as finance, economics, and business. The Percent Growth Rate Calculator provides a straightforward solution to determine the growth rate of a value over a specified period. Whether you’re an investor analyzing financial data or a business owner projecting future revenues, this calculator can be a valuable tool in your decision-making process.

How to Use

To utilize the Percent Growth Rate Calculator, follow these simple steps:

Enter the initial value (x₀) into the designated field.
Input the final value (x(t)) to which the initial value has grown.
Specify the time frame in years (t) over which the growth occurred.
Provide the growth rate per year (r) as a percentage.

Once these values are entered, click the “Calculate Growth Rate” button to obtain the percentage growth rate.

Formula

The formula used by the Percent Growth Rate Calculator is: $x (t) = x_{0} \times (1 + r)^{t}$

Where:

$x (t)$ is the final value after time $t$ ,
$x_{0}$ is the initial value,
$r$ is the growth rate per year (expressed as a percentage),
$t$ is the time in years.

Example

Suppose you invested $1,000 (initial value) and after 5 years, your investment grew to $1,500. To find the growth rate, plug in the values:

Initial Value ( $x_{0}$ ): $1,000
Final Value $x (t)$ ): $1,500
Time ( $t$ ): 5 years

$x (t) = 1000 \times (1 + r)^{5} = 1500$

By rearranging the formula, you can solve for the growth rate ( $r$ ).
