Calculate Percentages Now! →Basic Percentage Calculation
At its core, a percentage represents a part of a whole, expressed as a fraction of 100. The basic formula for calculating a percentage is:
Percentage = (Part / Whole) * 100
For example, if you have a dataset of 200 students, and 30 of them are majoring in biology, the percentage of biology majors is calculated as:
(30 / 200) * 100 = 15%
This means 15% of the students are biology majors.
Finding What Percent of a Number Is
Sometimes, you need to determine what percentage one number represents of another. For instance, if a company's revenue increased from $100,000 to $120,000, you might want to know the percentage increase.
Using our calculator, this is easy! Input the initial and final values to quickly see the percentage change. No manual calculations needed!
Calculating Percentage Change: Increase and Decrease
Percentage change is a common statistical measure used to describe the extent to which a quantity changes over time. It can be either an increase or a decrease. The formulas are:
Percentage Increase = ((New Value - Original Value) / Original Value) * 100
Percentage Decrease = ((Original Value - New Value) / Original Value) * 100
Consider a scenario where the price of a product increases from $50 to $60. The percentage increase is:
((60 - 50) / 50) * 100 = 20%
Conversely, if the price decreases from $50 to $40, the percentage decrease is:
((50 - 40) / 50) * 100 = 20%
