Constructive: Enhance
A optimistic % change signifies a rise. Which means that the ultimate worth is bigger than the preliminary worth. To calculate a optimistic % change, comply with these steps:
- Discover the distinction: Subtract the preliminary worth from the ultimate worth. If the result’s a destructive 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 proportion.
- Interpret the consequence: A optimistic % change signifies a rise. The magnitude of the % change tells you the extent of the rise.
For instance, for instance you will have 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’ll comply with these steps:
