1. What is Adding Percentage?

Adding a percentage to a number is a common mathematical operation used to calculate increases, markups, or growth rates. It's widely used in finance, economics, and everyday calculations.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( Number \) — The base value you want to increase
• \( Percentage \) — The percentage increase (as a decimal or whole number)

Explanation: The formula converts the percentage to a decimal, adds 1 to create a multiplier, then applies it to the original number.

3. Practical Applications

Details: This calculation is used for price markups, salary increases, investment growth, tax calculations, and many other financial operations.

4. Using the Calculator

Tips: Enter the base number and the percentage you want to add. The percentage can be entered as a whole number (e.g., 15 for 15%) or decimal (e.g., 0.15 for 15%).

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between adding percentage and percentage of?
A: Adding percentage increases the original number by that percentage, while percentage of calculates a portion of the original number.

Q2: How do I subtract a percentage instead?
A: Simply enter a negative percentage value (e.g., -10 for a 10% decrease).

Q3: Can I add multiple percentages?
A: This calculator handles a single percentage. For multiple percentages, you would need to chain calculations.

Q4: Does the order of operations matter?
A: Yes, percentages are applied sequentially. Adding 10% then 20% gives a different result than adding 20% then 10%.

Q5: How is this different from compound interest?
A: Compound interest applies percentage growth repeatedly over periods, while this is a single percentage application.
