How Does a Percentage Calculator Work?
A percentage calculator applies specific formulas based on what you need to calculate. Here’s how it can handle various calculations:
1. Percentage of a Value
Formula: Result = (Percentage/100 )× Total Value
Example: Find 15% of 250.
Calculation: (15/100)×250=37.5
2. Percentage Increase
Formula: Result = Total Value +( Percentage/100 ×Total Value)
Example: Calculate a 20% increase on $300.
Calculation: 300 + (0.20 × 300) = 360
3. Percentage Decrease
Formula: Result = Total Value – (Percentage/100×Total Value)
Example: What is a 25% decrease from $400?
Calculation: 400 – (0.25 × 400) = 300
4. Percentage of a Percentage
Formula: Result = (Percentage/100 × (Additional Percentage/100×Total Value)
Example: Find 10% of 25% of 600.
Calculation: (0.10) × (0.25× 600) = 15
