Formulas for Calculating Earnings Monthly Salary Monthly Salary = Annual Salary ÷ 12 (Converts yearly income to monthly) Weekly Salary Weekly Salary = Annual Salary ÷ 52 (Converts yearly income to weekly)
Formulas for Calculating Earnings Hourly Wage Hourly Wage = Total Pay ÷ Total Hours Worked (Used to find the rate per hour) Overtime Pay Overtime Pay = Hourly Rate × Overtime Hours × Multiplier (Common multipliers: 1.25 or 1.5)
Formulas for Calculating Earnings Commission Commission = Sales × Commission Rate (Pay based on a percentage of sales) Piecework Pay Piecework Pay = Num of Items × Rate per Item ( Pay based on productivity )
Formulas for Calculating Earnings Gross Pay Gross Pay = Regular Pay + Overtime + Commission + Piecework ( Total earnings before deductions ) Net Pay Net Pay = Gross Pay − Deductions (Final take-home pay after taxes and other deductions)
