Objective. Students will calculate regular and overtime gross pay for hourly and salaried non-exempt employees using FLSA rules, including weighted-average overtime for employees earning multiple pay rates.
This lesson, its worked examples and its practice questions has not yet been verified by a credentialed professional in the field or by a certification or approval body. It is a study draft and may contain errors. Do not use it as instructions for work on a job site or on live equipment. Always follow your instructor, your supervising professional, and current official references and regulations.
VoTechWorks program approval and accreditation are still in progress. Credentials are issued only by the certifying bodies named in each program, after their own exams.
Gross pay is the total amount an employee earns before any taxes or deductions are subtracted. Calculating it correctly is the first step in every payroll cycle. Errors at this stage ripple through withholding, employer taxes, and the employee's paycheck, so accuracy is not optional.
An hourly employee's regular gross pay equals the hourly rate multiplied by the number of hours worked during the pay period. For example, an employee who earns $15.00 per hour and works 40 hours earns $600.00 in regular pay. Keep all intermediate figures to at least four decimal places and round only the final dollar amount.
A salaried employee receives a fixed amount per pay period regardless of the exact hours worked—up to a point. Under the Fair Labor Standards Act (FLSA), an employee who is classified as non-exempt must receive overtime pay even if they are paid a salary. To find their regular rate of pay for a given workweek, divide the weekly equivalent of the salary by the total hours actually worked that week. This is called the regular rate of pay and it must be recalculated whenever hours vary.
The FLSA defines a workweek as any fixed, regularly recurring period of 168 consecutive hours—seven 24-hour days. An employer chooses the start day and it must remain consistent. Overtime is triggered when a non-exempt employee works more than 40 hours in a single workweek.
Never average hours across two workweeks to avoid overtime. Each workweek stands alone.
A piece-rate employee is paid a fixed amount per unit produced (pieces cut, forms processed, etc.). Gross pay for regular hours = piece rate × total pieces. The FLSA still requires overtime on piece-rate work. The most common method is the weighted-average (regular rate) method:
1. Calculate total piece-rate earnings for the workweek.
2. Divide total earnings by total hours worked to find the regular rate.
3. Pay the overtime premium (the additional 0.5 × the regular rate) for each hour over 40.
This is often called the "half-time" overtime method because the employee has already received the "straight-time" portion through piece-rate earnings.
When a non-exempt employee works at two or more pay rates in the same workweek, the FLSA requires the weighted-average method to find the correct regular rate:
1. Add all earnings from every rate together (total compensation).
2. Divide total compensation by total hours worked → weighted-average regular rate.
3. Multiply that rate by 0.5 × overtime hours worked for the overtime premium.
This ensures no rate is used alone to calculate overtime in a way that underpays the employee.
The FLSA permits employers to round employee time to the nearest 5 minutes, one-tenth of an hour, or quarter hour, provided the policy is neutral and does not consistently favor the employer. A rounding practice that always rounds down—always shortchanging employees—violates the FLSA regardless of written policy.
Missed punches must be resolved by using the best available evidence: supervisor records, security logs, or employee attestation. Document every correction in writing. Never alter a time record without a written explanation and authorization. Falsifying payroll records is a federal violation.
Underpaying overtime is one of the most common FLSA violations found in Department of Labor audits. Back wages, liquidated damages, and civil penalties can result. Overpaying creates budget problems and is difficult to recover. Both errors damage trust. Check your arithmetic twice, verify hours against source documents, and follow the employer's written policies—unless those policies would violate federal or state law, in which case the law governs.
This lesson uses only paper forms and calculators. No physical hazards apply. However, treat all sample employee data—even fictional names—with the same confidentiality habits you will use with real payroll data. Payroll records are sensitive; in a real workplace they are protected by company policy and, in some cases, by law.
Answer each question, then check it. Nothing is recorded; this is your own practice.
