Sometimes in our day to day we want to know about percentage in different ways for instance percentage increase or decrease or a percetange withing a percentage.
For percentage increase this is where numbers can get a little complex and we may even try to use a calculator for this.
But before we do let’s lok at what the formula is and how it looks like on paper (ahum screen):
1. Find the Difference: Subtract the original value from the new value (New – Original).
2. Divide by Original: Divide the difference by the original value.
3. Multiply by 100: Convert to a percentage.
Example: A price goes from $35 to $45.50. ($45.50 – $35) / $35 \* 100 = 30% increase.
Here is another example of how to get a percentage increase: Price increases from $5 to $15. We do 15 – 5 then divide by 5 and multiply by 100 or mathetmatically this looks like: (15 – 5) / 5 * 100. This equals to 200 or a 200% increase from 5 to 15.
