Understanding Percentage Calculations
Percentages are a fundamental concept in mathematics and everyday life. They represent a proportion out of 100, making it easier to compare different quantities.
Percentage Of a Number
This calculation finds what a certain percentage of a number is. The formula is:
Result = (Percentage / 100) × Number
For example, to find 20% of 500:
Result = (20 / 100) × 500 = 0.2 × 500 = 100
Percentage Change
This calculation determines the percentage increase or decrease between two values. The formula is:
Percentage Change = ((Final Value - Initial Value) / Initial Value) × 100
For example, if a product's price increases from $400 to $500:
Percentage Change = ((500 - 400) / 400) × 100 = (100 / 400) × 100 = 25% increase
Percentage Difference
This calculation finds the relative difference between two numbers as a percentage of their average. The formula is:
Percentage Difference = (|Value1 - Value2| / ((Value1 + Value2) / 2)) × 100
For example, comparing 300 and 400:
Percentage Difference = (|300 - 400| / ((300 + 400) / 2)) × 100 = (100 / 350) × 100 ≈ 28.57%
Reverse Percentage
This calculation finds the original value before a percentage change occurred. The formula depends on whether it was an increase or decrease:
For increase: Original Value = Final Value / (1 + (Percentage / 100))
For decrease: Original Value = Final Value / (1 - (Percentage / 100))
For example, if a price after a 20% increase is $120:
Original Value = 120 / (1 + (20 / 100)) = 120 / 1.2 = 100
Percentage Points
This calculation finds the absolute difference between two percentages. Unlike percentage change, this is a simple subtraction:
Percentage Points = Percentage2 - Percentage1
For example, if one candidate gets 40% of votes and another gets 60%:
Percentage Points Difference = 60 - 40 = 20 percentage points
