| Step 3: Convert that to a percentage (by multiplying by 100 and adding a "%" sign) |
| Note: when the new value is greater then the old value, it is a percentage increase, otherwise it is a decrease. |
Method 2:
| Step 1: Divide the New Value by the Old Value (you will get a decimal number) |
| Step 2: Convert that to a percentage (by multiplying by 100 and adding a "%" sign) |
