Examples of Percentage Decrease Calculations

Car Depreciation Example

Given:

  • Original Price: 30,000 (2021)
  • Current Price: 24,000 (2022)

Calculation:

[(30,000 - 24,000) / 30,000] × 100
= (6,000 / 30,000) × 100
= 20%

Result: 20% decrease (depreciation)

Discount Price Example

Given:

  • Original Price: 150
  • Sale Price: 120

Calculation:

[(150 - 120) / 150] × 100
= (30 / 150) × 100
= 20%
