Fold Change (FC) Calculator

Formula

The formula to calculate the fold change is:

\[ FC = \frac{\text{Final Value}}{\text{Initial Value}} \]

Where:

\( FC \) is the fold change
\( \text{Final Value} \) is the value at the end of the period
\( \text{Initial Value} \) is the value at the beginning of the period

What is Fold Change?

Fold change is a measure used in various fields such as finance, biology, and chemistry to describe how much a quantity changes between an original and a subsequent measurement. It is a ratio that compares the final value to the initial value, providing a simple way to express an increase or decrease. A fold change greater than 1 indicates an increase, while a fold change less than 1 indicates a decrease.

Example Calculation

Let's assume the following values:

Initial Value: 50
Final Value: 200

Step 1: Calculate the Fold Change (FC):

\[ FC = \frac{200}{50} = 4 \]

Therefore, the fold change is 4, indicating that the final value is 4 times the initial value.
