How do you calculate the percentage change?

50. How do you calculate the percentage change?

1. PercentChange = (NewValue) OldValue x 100
2. PercentChange = (OldValue + NewValue) OldValue x 100
3. PercentChange = ((NewValue - OldValue) / OldValue) x 100
4. PercentChange = (OldValue - NewValue) NewValue x 100

Answer

The correct answer is: C) PercentChange = ((NewValue - OldValue) / OldValue) x 100

Explanation

To compute the percentage difference between an old and new value use the following formula: ((NewValue - OldValue) / OldValue) 100

Where:

• OldValue represents the initial or "before" value.
• The ultimate value, or "after" value, is NewValue.
• This formula computes the percentage difference between the old and new values. The outcome specifies whether the change is positive or negative, and by how much.
