How to measure the increase from one value to another? The Fold Increase Calculator can help you calculate how much one number has increased relative to another. You simply enter the Original Number A and Final Number B into the calculator to find the Fold Increase A.
What is Fold Increase?
Fold increase concisely conveys how much a final number has grown compared to an original. It shows the factor by which the latter exceeds the former. For example, if the ending amount doubles the starting figure, the fold increase expresses simply as 2. Whether tracking growth over time, this calculation distills amplification into a single interpret able number.
How to Use the Calculator?
1. Basic Calculator:
Enter both the original and final numbers, and the calculator will give you the fold increase.
Example: If your Original Number A is 10 and your Final Number B is 30, the calculator will tell you that the fold increase is 3.
2. Advanced Calculator:
Input the Initial Value, Rate of Increase (%), and Number of Periods to calculate the final value after the given periods.
Example: If your Initial Value is 100, the Rate of Increase is 5%, and the Number of Periods is 3, the calculator will give you the final value.
Formula for Fold Increase:
The formula for calculating Fold Increase is:
$\text{FA:B} = \frac{B}$
Variables in the Formula:
Variable  Description 

Original Number A  The starting value 
Final Number B  The ending value 
Fold Increase A

The ratio of final to original value 
How To Calculate Fold Increase
Example 1:
Foe example, the original number is 50, and the final number is 150.
Plug in the values:
$$\text{FoldIncrease}=\frac{150}{50}=3$$
The Fold Increase is 3, meaning the final number is 3 times larger than the original number.
Example 2: If the original number is 20 and the final number is 40:
Plug in the values:
$$\text{FoldIncrease}=\frac{40}{20}=2$$$$$$
The Fold Increase is 2, meaning the final number is twice the original number.
FAQs
How do I calculate percent change in Excel?
To calculate percent change in Excel, use the formula: ((New Value  Old Value) / Old Value) * 100
. This will give you the percentage change between two numbers.
What is the difference between percent difference and percent change?
Percent change measures the increase or decrease between two values, while percent difference compares the relative difference between two values, often in comparison or error analysis.
How do you calculate a 6fold increase?
A 6fold increase means multiplying the original value by 6. For example, if the initial value is 10, a 6fold increase would result in a value of 60.
What is fold change, and how is it calculated in biology?
Fold change refers to the ratio of a new value to an old value, often used in biology to measure gene expression. A 2fold increase means the new value is twice the original value.
How do you calculate a negative fold change?
Negative fold change occurs when the new value is lower than the original value. It’s often calculated as a ratio, but if using log2 fold change, a negative value indicates a decrease in expression or quantity.
Conclusion
I hope you found the Fold Increase Calculator is a quick and effective tool to measure growth or increase between two numbers. Thank you for using our tool
