-
Multiply the decimal by 100:
To transform the decimal to a share, merely multiply it by 100. This gives you the % change.
-
Interpret the consequence:
The results of this multiplication is the % change between the 2 values. This share represents the relative change between the 2 values.
-
Add the % signal:
After getting the numeric worth of the % change, add the % signal (%) to point that it’s a share.
-
Interpret the signal of the % change:
A optimistic % change signifies a rise, whereas a adverse % change signifies a lower.
By following these steps, you possibly can precisely calculate the % change between two values and specific it as a share.
Interpret the consequence
After getting calculated the % change, the ultimate step is to interpret the consequence.
-
Optimistic % change:
A optimistic % change signifies a rise. Because of this the ultimate worth is bigger than the preliminary worth.
-
Destructive % change:
A adverse % change signifies a lower. Because of this the ultimate worth is lower than the preliminary worth.
-
Zero % change:
A zero % change signifies that there isn’t a change between the 2 values. Because of this the ultimate worth is identical because the preliminary worth.
-
Magnitude of the % change:

When decoding the results of a % change calculation, it is essential to think about the context and the precise values being in contrast. The % change can present helpful insights into tendencies, development charges, and adjustments over time.
Optimistic: Enhance
A optimistic % change signifies a rise. Because of this the ultimate worth is bigger than the preliminary worth. To calculate a optimistic % change, observe these steps:
- Discover the distinction: Subtract the preliminary worth from the ultimate worth. If the result’s a adverse quantity, take absolutely the worth.
- Divide by the unique worth: Divide absolutely the worth of the distinction by the unique worth.
- Multiply by 100: Multiply the results of the earlier step by 100 to transform it to a share.
- Interpret the consequence: A optimistic % change signifies a rise. The magnitude of the % change tells you the extent of the rise.
For instance, as an example you have got an organization that had gross sales of $100,000 in January and $120,000 in February. To calculate the % change in gross sales from January to February, you’d observe these steps:
- Discover the distinction: $120,000 – $100,000 = $20,000
- Divide by the unique worth: $20,000 / $100,000 = 0.2
- Multiply by 100: 0.2 * 100 = 20%

A optimistic % change can be utilized to characterize development, enchancment, or a rise in worth. It’s generally utilized in enterprise, economics, and finance to trace efficiency, analyze tendencies, and make knowledgeable selections.
Destructive: Lower
A adverse % change signifies a lower. Because of this the ultimate worth is lower than the preliminary worth. To calculate a adverse % change, observe these steps:
- Discover the distinction: Subtract the ultimate worth from the preliminary worth. If the result’s a adverse quantity, take absolutely the worth.
- Divide by the unique worth: Divide absolutely the worth of the distinction by the unique worth.
- Multiply by 100: Multiply the results of the earlier step by 100 to transform it to a share.
- Interpret the consequence: A adverse % change signifies a lower. The magnitude of the % change tells you the extent of the lower.
For instance, as an example you have got an organization that had gross sales of $100,000 in January and $80,000 in February. To calculate the % change in gross sales from January to February, you’d observe these steps:
- Discover the distinction: $100,000 – $80,000 = $20,000
- Divide by the unique worth: $20,000 / $100,000 = 0.2
- Multiply by 100: 0.2 * 100 = 20%
- Interpret the consequence: The gross sales decreased by 20% from January to February.
A adverse % change can be utilized to characterize a loss, decline, or a lower in worth. It’s generally utilized in enterprise, economics, and finance to trace efficiency, analyze tendencies, and make knowledgeable selections.
Zero: No change
A zero % change signifies that there isn’t a change between the 2 values being in contrast. Because of this the ultimate worth is strictly the identical because the preliminary worth.
To calculate a zero % change, you’d observe the identical steps as for calculating a optimistic or adverse % change. Nevertheless, while you divide the distinction by the unique worth, the consequence will probably be zero.
For instance, as an example you have got an organization that had gross sales of $100,000 in January and $100,000 in February. To calculate the % change in gross sales from January to February, you’d observe these steps:
- Discover the distinction: $100,000 – $100,000 = $0
- Divide by the unique worth: $0 / $100,000 = 0
- Multiply by 100: 0 * 100 = 0%
- Interpret the consequence: The gross sales remained the identical from January to February.
A zero % change can be utilized to characterize stability, consistency, or the absence of change. It’s generally utilized in enterprise, economics, and finance to trace efficiency, analyze tendencies, and make knowledgeable selections.
