What is a Percentage? The Foundation of Proportions
A percentage is a way of expressing a number or a ratio as a fraction of 100. It’s denoted by the percent sign (“%”). For example, 50% means 50 out of 100, or 1/2. Percentages are fundamental in various aspects of life because they provide a standardized way to compare quantities and express proportions, making them easily understandable across different contexts.
Key Concepts:
- Whole (Base): The total amount or original value.
- Part: A portion of the whole.
- Rate (Percentage): The part expressed as a fraction of 100 of the whole.
Understanding these basic concepts is the first step to confidently using our ZYNTRA Percentage Calculator.

Understanding Percentage Calculations: Formulas & Examples
For those who want to delve deeper, here are the underlying formulas and more examples for each type of percentage calculation:
Example: To find 25% of 80: $(25/100) \times 80 = 0.25 \times 80 = 20.$
Real-world: A jacket costs $60 and is 15% off. Discount = $(15/100) \times 60 = $9. Final price = $60 – $9 = $51.
Example: To find what percentage 15 is of 60: $(15/60) \times 100 = 0.25 \times 100 = 25%.$
Real-world: You scored 45 out of 50 on a test. Your percentage score = $(45/50) \times 100 = 90%.$
Example (Increase): From 40 to 50: $((50-40)/40) \times 100 = (10/40) \times 100 = 0.25 \times 100 = 25\%$ increase.
Example (Decrease): From 50 to 40: $((40-50)/50) \times 100 = (-10/50) \times 100 = -0.2 \times 100 = -20\%$ (20% decrease).
Real-world: Your stock value went from $1000 to $1200. Percentage increase = $((1200-1000)/1000) \times 100 = 20%.$
Example (Add): Add 10% to 50: $50 \times (1 + (10/100)) = 50 \times 1.10 = 55.$
Example (Subtract): Subtract 10% from 50: $50 \times (1 – (10/100)) = 50 \times 0.90 = 45.$
Real-world: A product costs $80, and sales tax is 7%. Final price = $80 * (1 + (7 / 100)) = $80 * 1.07 = $85.60.
Example: If 60 is 20% of the original number: $60 / (20/100) = 60 / 0.20 = 300.$
Real-world: After a 20% discount, a shirt costs $40. What was the original price? $40 / (1 – (20 / 100)) = 40 / 0.80 = $50.
