Percentage Calculation Formulas Explained
The Percentage Calculator uses standard mathematical formulas.
Percentage Formula
Percentage = (Part ÷ Total) × 100
Percentage Increase Formula
Percentage Increase = ((New − Original) ÷ Original) × 100
Percentage Decrease Formula
Percentage Decrease = ((Original − New) ÷ Original) × 100
Percentage Added or Subtracted
Final Value = Base Value ± (Base Value × Percentage ÷ 100)

- Discount: 15%
Discount = $200 × 15 ÷ 100 = $30
Final price = $170
