Calculation Formula
Year-over-Year Rate = (Current Year Value - Last Year Value) / Last Year Value × 100%
Where:

Example
Suppose a company's revenue last year was 1 million yuan, and this year's revenue is 800,000 yuan:
- Current Year Value: 800,000 yuan
- Last Year Value: 1,000,000 yuan
- Year-over-Year Decline Rate = (800,000 - 1,000,000) / 1,000,000 × 100% = -20%
This means the company's revenue declined by 20% year-over-year this year.
