How to Calculate Time and a HalfEvery Scenario, Step by Step

First find the regular rate that applies to the workweek. For a single hourly wage, multiply that rate by 1.5 to get the overtime rate. Next count the qualifying overtime hours, usually hours actually worked above 40 in the employer's fixed workweek under the federal FLSA. Multiply the overtime rate by those hours to find overtime pay, then add regular pay for the hours below the threshold. For example, a $20 rate and 45 worked hours produce a $30 overtime rate, $800 regular pay, $150 overtime pay, and $950 gross weekly pay. This simple formula changes when compensation includes a nondiscretionary bonus, a shift differential, multiple rates, or a state daily-overtime rule. Those items can change the regular rate or move hours into overtime earlier. Paid holiday leave that was not worked usually does not count toward the federal 40-hour test. Use the calculator as an estimate, keep the workweek boundary visible, and compare each component with the earnings codes on the pay stub rather than checking only the final total.

A salary does not by itself answer the overtime question. If the employee is nonexempt, divide annual salary by 52 to find weekly salary, then divide by the agreed straight-time hours to find an equivalent hourly rate. Multiply that rate by 1.5 and by the overtime hours. A $41,600 salary produces $800 per week; with a 40-hour schedule, the equivalent rate is $20, the overtime rate is $30, and 10 overtime hours add $300 for an estimated $1,100 week. Some employers use a fluctuating workweek method in which a fixed salary covers all straight-time hours and only a half-time premium is added. The same 50-hour example would use $800 divided by 50, or $16, then $16 x 0.5 x 10 = $80, for $880. The FWW method has strict prerequisites and is not automatically lawful. Exempt status depends on salary basis, salary level, and actual duties, not a manager title. Check the current DOL guidance, the offer terms, deductions, and job duties before assuming a salary means no overtime.

A nondiscretionary bonus tied to production, attendance, performance, or a promised formula generally must be allocated across the hours in the period when it was earned. Add straight-time wages and the bonus, divide by total worked hours, and use the adjusted regular rate to calculate the additional half-time premium for overtime hours. For $18 per hour, 48 hours, and a $144 production bonus, straight-time wages are $864, total compensation is $1,008, and the adjusted regular rate is $21. Eight overtime hours require an additional $21 x 0.5 x 8, or $84. The estimated total is $1,092. The extra payment is a half-time adjustment because the employee already received the straight-time wage for all 48 hours; it is not another full 1.5x payment on top of the same hours. A discretionary bonus whose amount and timing are genuinely controlled by the employer may be excluded, as can certain gifts and reimbursements. Ask payroll which rule was applied, keep the bonus plan, and verify that the calculation did not use only the base wage.

Federal overtime generally uses a weekly threshold of 40 hours, while California generally adds daily thresholds. Hours above 8 and through 12 in a workday are usually paid at 1.5x, and hours above 12 are usually paid at 2.0x. California also has seventh-consecutive-day rules and industry-specific exemptions. Daily overtime hours are not counted again as weekly overtime hours, so the calculation removes premium hours before testing remaining straight-time hours against 40. In the guide example, a worker at $20 has 10 hours Monday, 8 Tuesday, 13 Wednesday, 8 Thursday, and 6 Friday. Daily premiums apply to 2 Monday hours, 4 Wednesday hours, and 1 Wednesday double-time hour. The daily result is $980, compared with $950 under the simplified federal weekly calculation. A weekly total alone cannot reproduce a California timecard because the distribution by day matters. Use the California tab for an estimate, keep a daily record, and confirm the current rule with the California Department of Industrial Relations. Collective bargaining agreements and industry wage orders can change the outcome.

Under the FLSA, overtime is calculated separately for each employer-defined workweek, even when the employer pays every two weeks or twice a month. An 80-hour pay period can contain 45 hours in week one and 35 in week two, which means five overtime hours in week one and none in week two. It cannot be averaged into 40 hours per week. The employer's fixed workweek may start Sunday, Monday, or another day, but it must remain a recurring seven-day period. A pay-period calendar is not a substitute for that workweek. State rules, collective bargaining agreements, and special public-sector arrangements can be more protective, so compare the timecard with the governing policy. When auditing a biweekly pay stub, split the dates at the workweek boundary, calculate regular and overtime hours for each week, and then add the two weekly totals. The calculator can scale a weekly estimate for planning, but it should not be used to hide the separate thresholds. Save the employer's written workweek definition because a missing or changed boundary can explain why a payroll total differs from your first calculation.

The fluctuating workweek, or FWW, is a method in which a fixed salary is intended to cover all straight-time hours, even though the number of hours changes from week to week. Because the salary already covers straight time, the overtime payment is generally an additional half-time premium based on the weekly salary divided by actual hours. In the guide's $41,600 example, the weekly salary is $800. At 50 actual hours, the FWW rate is $16 and 10 overtime hours add $80, producing $880. That is lower than the $1,100 result under a fixed 40-hour salary method. The lower result does not mean an employer can label any salary arrangement FWW after the fact. The salary must be fixed, hours must genuinely fluctuate, the parties must understand the arrangement, and applicable state law and agreements must permit it. Deductions or a promise that the salary covers only a fixed number of hours can undermine the method. Ask for the written compensation arrangement, verify the current DOL rules, and have payroll or a qualified wage attorney review unusual patterns before treating the FWW result as final.

When one employer pays two rates in the same workweek, a weighted regular rate is usually needed. Multiply each rate by the hours worked at that rate, add the straight-time earnings, and divide by all hours. For 24 hours at $16 and 20 hours at $20, the earnings are $384 plus $400, or $784. Divide by 44 hours to get a weighted rate of about $17.82. The 1.5x overtime rate is about $26.73, and four overtime hours create about $106.91 in overtime pay. The page displays the PRD example total of $890.91, while an employer may show straight-time and premium amounts under separate codes. If two jobs are for unrelated employers, each employer generally counts only its own hours. Thirty hours for Employer A and 20 for Employer B do not automatically create overtime for either one. Joint employers, staffing agencies, and shared supervision can change the analysis. Keep schedules, job assignments, rate notices, and both pay stubs. Ask HR which entity is the legal employer and which weighted-rate method it uses before comparing your result with payroll.

Start by preserving the evidence that explains the difference. Save schedules, clock records, corrected timecards, pay stubs, bonus plans, rate notices, the employee handbook, and any message about your classification or workweek. Reconstruct the employer-defined workweek rather than averaging a pay period. Identify the regular rate, including any compensation that should be included, separate daily and weekly overtime where state law requires it, and write down the formula that produced your result. Then send HR or payroll a focused written question with the dates, hours, rate, policy language, and the specific earnings code that appears wrong. Ask for the employer's calculation and a correction timeline. If the issue is not resolved, contact the U.S. Department of Labor Wage and Hour Division or your state labor agency. Union workers may need to use a grievance procedure with a short deadline. FLSA recovery commonly reaches two years, or three for willful violations, but facts and filing rules vary. Do not retaliate against coworkers or alter records. A wage-and-hour attorney can help when the dispute involves joint employers, arbitration, classification, multiple states, or a large amount of back pay.
