Percentage increase measures how much a quantity has grown in terms of a percentage relative to its original amount.
Percentage Increase = ((New Amount – Original Amount) / Original Amount) × 100
If a product price goes from $100 to $120:
Yes. If the new amount is lower than the original, you’d have a percent change that’s negative, indicating a decrease.
If your monthly expenses increased from $500 to $600, you can see a 20% rise in costs. It helps identify areas to reduce spending.
