How do I calculate percentage increase?

Subtract the original value from the new value, divide by the original value, and multiply by 100. Example: from 500 to 650 → (150 ÷ 500) × 100 = 30%.

What if the new value is smaller?

Then the value decreased, and the result will be negative — use the percentage decrease calculator for a clearer breakdown.
