FAQ

How do I calculate percentage?

Percentage = (Part / Whole) × 100. Example: 25 out of 200 = (25/200) × 100 = 12.5%.

How do I calculate percentage increase?

% increase = ((New − Old) / Old) × 100. If a price went from $50 to $65: ((65−50)/50) × 100 = 30% increase.

What is percentage off?

Multiply the original price by the discount percentage and subtract. $80 at 25% off: 80 × 0.25 = $20 discount → $60 final price.
