The percentage change calculator is designed to calculate the percent (%) change (increase or decrease) between two given numbers.
The percentage change calculator is a free tool that determines the percent increase or decrease between the starting and final values. Also, it gives the difference between two given values and calculation steps.
It's a percent increase or decrease measured between two values. For example, if the final value increases X% from the starting value, we can say there is an X% change. Similarly, if the final value decreases Y% from the starting value, we can say there is a Y% change. The positive change denotes an increase and the negative change denotes a decrease.
The percentage change is calculated using the following formula.
Percent Change = 

× 100 
Where,
X_{1} = Starting value,
X_{2} = Final value.
Let's take some examples.
Suppose, the starting value is $9500 and the final value is $12000. Calculate the percentage change between given values.
Here,
Starting value (X_{1}) = $9500,
Final value (X_{2}) = $12000.
Now, place the above values in the percentage change formula.
Percent Change = 

× 100 
= 

× 100  = 26.31% 
So, the final value is 26.31% increased from the starting value.
Suppose, a product cost is $45 and there is a flat discount of $10 on the selling price. Calculate how much percent you saved.
Here,
Starting value (X_{1}) = $45,
Final value (X_{2}) = $45  $10 (flat discount) = $35.
Percent Change = 

× 100 
= 

× 100  = 22.22% 
Therefore, you saved 22.22% from the original price.
Suppose, the starting value is $100 and a percentage change is 20%. Calculate the final value based on the given parameters.
Here,
Starting value (X_{1}) = $100,
Percent Change = 20%.
Percent Change = 

× 100 
20% = 

× 100 
X_{2} = 20 + 100 = 120
So, after a 20% change, the final value would be $120.
Also, you can use the following formula to directly calculate the final value.
Final Value(X_{2}) = 

= 

= 120
