How do I calculate percentage increase?

Subtract the original value from the new value to get the absolute change, divide that change by the original value, then multiply by 100. For example, going from 120 to 150 is a 30 increase, and 30 ÷ 120 × 100 = 25%.

What is the formula for percentage growth?

The standard formula is ((new value - original value) ÷ original value) × 100. It measures how much the new number grew compared with the starting number.

Can the result be negative?

Yes. If the new value is lower than the original value, the result becomes negative. That means the change is really a decrease, not an increase.
