How to Use the Percentage Calculator

Using the Percentage Calculator is very straightforward. It includes three simple sections depending on the kind of percentage calculation you want to perform. Here’s a step-by-step guide on how to use each section of the tool:

1. Calculate: What is X% of Y?

This is one of the most common percentage calculations.

Example:

You want to find out what is 25% of 300.

Steps:

• Enter 25 in the first input box labeled “What is”.
• Enter 300 in the next box labeled “% of”.
• Click the CALCULATE button.
• The result will appear in the result box (in this case, 75).

This is useful for calculating:

• Discounts (e.g., 15% off a product price)
• Taxes (e.g., 5% GST on an invoice)
• Commissions, tips, or any proportionate amount

2. Calculate: X is what percent of Y?

This calculation helps you find what percentage one number is of another number.

Example:

If you want to know 75 is what percent of 300.

Steps:

• Enter 75 in the first box.
• Enter 300 in the second box.
• Click CALCULATE.
• The result will show 25%.

This is commonly used in:

• Exam scores (e.g., 40 out of 50 marks is what percent?)
• Performance metrics
• Business reporting (e.g., profit margin or productivity)

3. Calculate: Percentage Increase/Decrease

This section calculates how much one value has increased or decreased compared to another, expressed as a percentage.

Example:

Let’s say a product’s price increased from 200 to 250.

Steps:

• Enter 200 in the first box (original value).
• Enter 250 in the second box (new value).
• Click CALCULATE.
