How To Calculate Percentage In Calculator?

 

Method 1: Using the percentage button (%):

This method is available on most basic calculators. Here's how to do it:

1. Enter the whole value (the total amount or quantity).
2. Press the multiply button (×).
3. Enter the percentage value (without the percent sign). For example, for 20%, enter 20.
4. Press the percentage button (% again).

The calculator will display the part representing the given percentage of the whole value.

Example:

• What is 15% of 500?

  1. Enter 500.
  2. Press ×.
  3. Enter 15.
  4. Press %.

The calculator will show 75, which means 15% of 500 is 75.

Method 2: Manual calculation:

If your calculator doesn't have a dedicated percentage button, you can still calculate percentages manually using this formula:

percentage = (part/whole) × 100

1. Divide the part value by the whole value.
2. Multiply the result by 100.

Example:

• What is 25% of 80?

  1. Divide 25 by 80: 25 ÷ 80 = 0.3125
  2. Multiply by 100: 0.3125 × 100 = 31.25

Therefore, 25% of 80 is 31.25.

Remember, regardless of your chosen method, enter the percentage value without the percent sign.
