To calculate percentage increase: ((New Value - Original Value) / Original Value) × 100. For example, if a price increases from $100 to $120, the percentage increase is ((120-100)/100) × 100 = 20%.
Percentage change compares a new value to an original value, while percentage difference compares two values without considering which is the "original." Percentage difference uses the average of the two values as the base.
Yes! Percentages can exceed 100%. For example, if something doubles in size, that's a 100% increase. If it triples, that's a 200% increase. Percentages over 100% are common in growth calculations.
