What Is Overtime Pay Base?
Definition
Under China's Labour Law Art. 44, overtime pays 150% (weekday overtime), 200% (rest days without compensatory leave) or 300% (statutory holidays) of the wage. The base is the contractual monthly wage (not below local minimum wage), converted to a daily rate using 21.75 paid days per month ((365-104)÷12) and an hourly rate (÷8). Note: 21.75 is the monthly paid-days factor used for conversion, not your actual attendance count.
Formula
Hourly = monthly ÷ 21.75 ÷ 8; weekday overtime = hourly × 1.5 × overtime hours
Worked Example
Monthly wage 8700 → hourly 8700÷21.75÷8 = 50 CNY. A month with 10 weekday overtime hours plus one statutory holiday (8h): overtime = 50×1.5×10 + 50×3×8 = 750 + 1200 = 1950 CNY.
Common Misconception
Assuming rest-day overtime always pays double — the employer may substitute compensatory leave first. Assuming bonuses and allowances enter the base — most jurisdictions use "regular working-hours wages"; meal/transport allowances and one-off bonuses are typically excluded.
