The calculator evaluates standard percentage relationships using the fundamental formula: Percentage = (Part / Total) × 100. It also computes percentage increase: ((New - Original) / Original) × 100, and percentage discounts: Original × (1 - Discount / 100).
Divide the first number (the part) by the second number (the total) and multiply the result by 100. For example, (30 / 120) × 100 = 25%.
