Formula 1: Finding a Percentage of a Number

Formula:

Percentage Value = (Percentage ÷ 100) × Number

(15 ÷ 100) × 800

= 120

Result:

15% of 800 = 120

Formula:

Percentage = (Part ÷ Total) × 100

Example:

40 out of 200:

(40 ÷ 200) × 100

= 20%

Result:

40 is 20% of 200

Formula 3: Percentage Increase

Formula:

Percentage Increase = ((New Value - Original Value) ÷ Original Value) × 100

Example:

Original value: 100

New value: 150

Increase:

((150 - 100) ÷ 100) × 100

= 50%

Formula 4: Percentage Decrease

Formula:

Percentage Decrease = ((Original Value - New Value) ÷ Original Value) × 100

Example:

Original value: 500

New value: 400

Decrease:

((500 - 400) ÷ 500) × 100
