Percentage Formula
Percentage = (Part / Whole) × 100
To find the part: Part = (Percentage / 100) × Whole
Percentage Formula
The basic percentage formula is:
Percentage = (Part / Whole) × 100
For finding a part when the percentage and whole are known:
Part = (Percentage / 100) × Whole
In our example:
- Percentage = 15%
- Whole = 28000
- Part = (15 / 100) × 28000 = 4200
Practical Examples
Here are some real-world scenarios where calculating percentages is useful:
Discount Calculation
If an item costs $28000 and has a 15% discount, the discount amount is 4200. The final price would be 28000 - 4200 = 23800.
Tax Calculation
If a product costs $28000 and has a 15% sales tax, the tax amount is 4200. The total cost including tax would be 28000 + 4200 = 32200.

If an employee's salary is $28000 and receives a 15% raise, the increase amount is 4200. The new salary would be 28000 + 4200 = 32200.
| Scenario | Calculation | Result |
|---|---|---|
| Discount | 28000 × 0.15 = 4200 | Final price: 23800 |
| Tax | 28000 × 0.15 = 4200 | Total cost: 32200 |
| Salary Increase | 28000 × 0.15 = 4200 | New salary: 32200 |
