Calculation Example

Let's work through some sample percentage calculations:

Example 1: What is 20% of 150?
Given Values:
Value = 150
Percentage = 20%
Formula:
Result = (Value × Percentage) ÷ 100
Step-by-Step Solution:
Step 1: 150 × 20 = 3,000
Step 2: 3,000 ÷ 100 = 30
Answer: 30
Example 2: What is the percentage change from 80 to 100?
Given Values:
Original Value = 80
New Value = 100
Formula:
Percentage Change = ((New - Original) ÷ Original) × 100
Step-by-Step Solution:
Step 1: 100 - 80 = 20
Step 2: 20 ÷ 80 = 0.25
Step 3: 0.25 × 100 = 25%
Answer: 25% increase
