How overtime pay is calculated

What this calculation answers

An overtime calculation answers one practical question: how much gross pay is due when a covered nonexempt employee works more than 40 hours in one fixed FLSA workweek. On Firefox, the browser does not change the math; it only gives you a convenient place to keep the calculator open beside timesheets, payroll notes, or source schedules.

The United States federal baseline uses a fixed 168-hour workweek made of seven consecutive 24-hour periods. Under the FLSA, covered nonexempt employees must receive overtime pay for hours worked in excess of 40 in that workweek at not less than 1.5 times the regular rate. More protective state rules, contracts, or policies can require a greater benefit.

Use the correct workweek

The workweek is the unit that controls the calculation. Each FLSA workweek stands alone, so you cannot average two weeks together to avoid overtime. If a covered nonexempt employee works 36 hours in week one and 46 hours in week two, the second week still has 6 overtime hours even though the two-week average is 41 hours.

Federal law does not create daily overtime or automatic weekend or holiday premium pay as such. Saturday, Sunday, holiday, or rest-day work counts like any other hours worked unless those hours push the covered nonexempt employee over 40 in the fixed workweek, or a state law, employer policy, union contract, or employment agreement provides a different premium.

Apply the overtime formula

For a single hourly rate, split total hours into regular hours and overtime hours. Regular hours are capped at 40 under the federal baseline, and overtime hours are hours over 40. Multiply regular hours by the regular rate, multiply overtime hours by 1.5 times the regular rate, then add both amounts.

Example: a covered nonexempt payroll assistant works 45 hours in one fixed FLSA workweek at a $29.20 regular hourly rate. Regular pay is 40 × $29.20 = $1,168.00. Overtime pay is 5 × $43.80 = $219.00. Total gross pay for the week is $1,387.00 before taxes, deductions, reimbursements, or any additional state-required premium.

Keep Firefox inputs clean

Firefox is useful for a quick overtime check when the source data is already open in another tab. Keep the payroll period, timecard, and calculator in the same window, then use print or save-to-PDF for the calculation record if your review process needs an attachment. Autofill can speed up repeated names or rates, but it should not replace checking the actual workweek hours.

The common browser-side mistake is carrying over a prior employee's hours or rate into a new calculation. Before relying on the result, confirm four items: worker status, fixed workweek dates, hours actually worked, and the regular rate. The regular rate is total compensation for the workweek, excluding statutory exclusions, divided by total hours actually worked in that workweek.

When records need workflow

A one-off calculator is enough when you are checking one employee, one fixed workweek, one regular rate, and no special state, contract, or policy rule changes the result. It is also enough for a fast estimate before payroll review, as long as the final payroll record comes from verified time and pay data.

A managed workflow is the better fit when overtime repeats across a team, managers need an approval trail, or payroll needs durable records. Everhour Overtimes supports daily and weekly overtime limits, 1.5x and 2x tiers, Team Hours overtime visibility, and payroll calculations based on employee hourly cost and tracked time.

Frequently Asked Questions

Does Firefox change the overtime calculation?

No. Firefox does not change the federal overtime formula, the FLSA workweek, or the 1.5x multiplier. The browser only affects your workflow: where you keep the calculator, source timesheets, payroll notes, and saved PDF or print records while you review the numbers.

Which hours count before overtime starts?

Under the federal FLSA baseline, covered nonexempt employees earn overtime for hours worked in excess of 40 in one fixed workweek. Paid vacation, holiday pay for time not worked, and similar paid leave are not federally required as hours worked under the FLSA unless another policy, contract, or applicable law treats them differently.

Can two short weeks be averaged together?

No. Each FLSA workweek stands alone for overtime calculations. Hours may not be averaged over two or more workweeks to avoid overtime. A 34-hour week followed by a 46-hour week still produces 6 overtime hours in the second week for a covered nonexempt employee under the federal baseline.

What is the regular rate in the formula?

The regular rate is total compensation for the workweek, excluding statutory exclusions, divided by total hours actually worked in that workweek. For a simple hourly employee with no other includable compensation, the regular rate is usually the hourly rate. Bonuses, shift differentials, or other compensation can change the regular rate when they are includable.

Is weekend or holiday work automatically overtime?

No. The FLSA does not require overtime pay merely because work occurs on Saturdays, Sundays, holidays, or regular days of rest. Under the federal baseline, the trigger is hours worked over 40 in the workweek unless a more protective state law, employer policy, union contract, or employment agreement applies.

How does Everhour calculate overtime for teams?

Everhour Overtimes lets admins set daily and weekly overtime limits, review regular, 1.5x overtime, and 2x double overtime tiers, and see overtime in Team Hours. The Payroll dashboard calculates overtime pay and gross pay from employee hourly cost and tracked time.

How does Everhour support overtime reporting?

Everhour Reporting can surface overtime and double-overtime data in Team Hours and configurable reports. Admins can add columns, group data by member or project, filter date ranges, and export reports in CSV, Excel/XLSX, or PDF for payroll review.

Move overtime into payroll review

Track approved hours, apply overtime limits, and review payroll totals in Everhour when repeated manual checks need team-level visibility and overtime pay from tracked time.
