Basic Utilities
A percentage calculator is a daily math utility designed to solve the three most common percentage problems encountered in business, retail, and everyday life. Whether you are trying to calculate a discount, figure out a profit margin, or determine tax rates, this tool handles the math instantly.
This tool provides three distinct calculation engines, each solving a different mathematical relationship:
This mode is primarily used for finding discounts or tax amounts. For example, if you want to find out what a 20% discount on a $150 item is, the answer is $30.
Result = (X / 100) × Y
Example: (20 / 100) × $150 = $30
This mode calculates proportions. If you scored 45 out of 60 on a test, you want to know what percentage that is.
Result = (X / Y) × 100
Example: (45 / 60) × 100 = 75%
This mode is crucial for business and finance. It tells you exactly how much a value grew or shrank relative to its starting point. If a stock goes from $50 to $60, it represents a 20% Increase.
Result = ((New Value - Old Value) / Old Value) × 100
Example: (($60 - $50) / $50) × 100 = 20%
