(X / Y) × 100. So 45 out of 60: (45 / 60) × 100 = 75%.

New value = original × (1 + percentage / 100). A salary of ₹50,000 with a 12% raise: ₹50,000 × 1.12 = ₹56,000.

((new − old) / old) × 100. Revenue went from ₹80,000 to ₹95,000: ((95,000 − 80,000) / 80,000) × 100 = 18.75% increase.

Percentage change has a direction — it measures how much one value changed from another. Percentage difference is symmetric — it measures how far apart two values are without implying which came first.
