# Find Growth Decay Percentage Calculator – How To

Are you looking for a calculator which solves your all problems? If yes, then you are in the place, where you can easily get information to find Growth/Decay percentage calculator.

This calculator is used for dual purposes, which means it is designed to give you information about your required details, whether it is about growing or shrinking, in both cases, it will give results. So, let’s dive into depth details!

## What is the difference between Growth percentage and Decay percentage?

These words are different from each other, and these two words are the core things that give you overall details of your queries. Where Growth is known as the ‘appreciation’ which means it adds some value. In simple terms, growth means an increase in value.

Where Decay is known as the shrinking, which is referred to as a ‘depreciation’ when searching results for something. But if you use it in mathematics, then both growth and decay can be put together, by keeping in mind that growth can be negative or positive.

## What is the benefit of the Growth and Decay percentage calculator?

Keep in mind that the process of measuring the reproduction pattern is no easy task, to get the best results you need an accurate calculation of growth. The use of resources and estimate of growth can be predicted by utilizing the core concept of exponential growth.

With the help of exponential growth, you can also calculate the results by estimating the reproduction cycle of different species. Exponential ‘e’ is used to determine the continuous growth of the various species, especially the bacteria and radioactive decay.

Keep in mind that ‘e’ is the universal constant that indicates the speed of growth and with this, you can easily include the time factor. The purpose of the time factor will give you the idea that how much it will increase in a specific time.

## How you can find a growth/decay percentage calculator by formula?

Using the below formula, you can easily find the growth/decay percentage,

•  For Exponential Growth

y = a(1 + r)x

•  For Exponential Decay

y = a(1 – r)x

• Keep in mind that growth “rate” (r) is only determined as b = 1+ r
• The decay “rate” (r) is only determined as b = 1 – r

Where a = is the initial value (it is the amount before measuring decay or growth)

Where r = is the decay rate or growth rate ( represented as the percentage and expressed as a decimal)

Where x = is the time intervals, which are passed.

### 1. How can I calculate growth and decay percentage?

Answer. Exponential decay is the process of overall reducing an amount by a given percentage rate, in a specific period. You can use the formula y = a(1-b)x, where a is the original amount, y is the final given amount, b is the factor of decay, and x is the specific time that passed.

### 2. How can I find the percent decay?

Answer. All you need to do is simply divide the result from the last given step, by the total number of times.
