The calculator uses the basic percentage formula:

Where:

• \( Value \) — The original number or total amount
• \( Percentage \) — The percentage value you want to calculate
• \( Result \) — The calculated portion of the value

Example: To calculate 1% of 100:
\( 100 \times \frac{1}{100} = 100 \times 0.01 = 1 \)

5. Frequently Asked Questions (FAQ)

Q1: How do I calculate percentage of a number?
A: Multiply the number by the percentage divided by 100. For example, to find 15% of 200: 200 × (15/100) = 30.

Q2: What is the formula for percentage?
A: The basic formula is: (Part/Whole) × 100 = Percentage, or Value × (Percentage/100) = Result.

Q3: How do I calculate percentage increase?
A: [(New Value - Original Value) / Original Value] × 100. For example, from 50 to 75: [(75-50)/50] × 100 = 50% increase.

Q4: How do I calculate percentage decrease?
A: [(Original Value - New Value) / Original Value] × 100. For example, from 80 to 60: [(80-60)/80] × 100 = 25% decrease.

Q5: Can I calculate multiple percentages?
A: Yes, you can use this calculator for any percentage calculation by changing the input values accordingly.
