FAQs
How do I calculate a percentage increase?
Subtract the original value from the new value, divide by the original value, then multiply by 100. For example: price goes from $80 to $100 — increase = (100 - 80) / 80 × 100 = 25%.
How do I find X% of a number?
Multiply the number by the percentage divided by 100. For example, 15% of 200 = 200 × (15/100) = 30. Or simply: 200 × 0.15 = 30.
What is the difference between percentage and percentage points?
Percentage is relative; percentage points are absolute. If an interest rate rises from 2% to 5%, it increased by 3 percentage points but by 150% as a relative change. This distinction matters in finance and economics.
