1. What is Add a Percentage to a Number Calculator?

Definition: This calculator computes a new number after adding a specified percentage to an original number.

Purpose: It helps in financial calculations, price adjustments, statistical analysis, and any scenario where you need to increase a value by a percentage.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• Number — The original value you want to increase
• Percentage — The percentage amount to add to the original number
• New Number — The resulting value after the percentage increase

Explanation: The percentage is converted to a decimal (divided by 100), multiplied by the original number to get the increase amount, which is then added to the original number.

3. Practical Applications

• Calculating price increases (e.g., adding 15% to a product cost)
