“Time and a half” is usually explained as one and one-half times your hourly wage. That shortcut works only when the wage is the whole pay story. Under the federal Fair Labor Standards Act, the multiplier applies to the regular rate, and that rate must be computed from the workweek’s includable pay.
The difference is visible in a week with a bonus. Take an employee paid $20 per hour who works 45 hours and receives a $100 nondiscretionary weekly bonus. The familiar shortcut puts the week at $1,050.00: it treats the stated wage as the regular rate, prices each of the five overtime hours at $30, and sets the bonus beside that calculation rather than inside it. The regular-rate method puts the same week at $1,055.56.
That is $5.56 more for a single workweek. The hours did not change and neither did the stated wage. The answer changed because the bonus belonged in the rate before the overtime premium was calculated.
The U.S. Department of Labor’s Fact Sheet #23 states the federal rule directly: covered, non-exempt employees must receive overtime for hours over 40 in a workweek at not less than one and one-half times their regular rates of pay. The words “regular rate” carry the calculation.

The regular rate is a weekly calculation
An hourly wage is a stated amount for an hour of work. The regular rate is the average hourly rate produced after the workweek’s includable remuneration and worked hours are known. Those two rates often happen to match, but they are not interchangeable definitions.
Start with the straight-time remuneration that belongs in the federal calculation. Then divide it by the hours actually worked. 29 CFR 778.109 supplies that general hourly-rate method, while 29 U.S.C. §207(e) defines the regular rate by beginning with remuneration for employment and then identifying statutory exclusions.
When base wages are the only includable remuneration, the calculation returns to the stated wage. A plain week at $20 per hour illustrates why the shortcut sometimes appears universal even though it is not.
- Straight time for 45 hours
- $900.00
- Regular rate
- $20.00
- Premium for 5 overtime hours
- $50.00
- Total pay
- $950.00
The straight time already pays all 45 worked hours. The additional overtime amount is one-half of the regular rate for the 5 hours over 40.
The last point prevents a common double count. Total straight-time remuneration already contains the ordinary pay for the overtime hours. After that total produces the regular rate, the federal method adds a half-time premium for the hours over the weekly threshold. Together, the straight time already paid and the added half produce time and one-half for those hours.
A nondiscretionary bonus changes the answer
Now add the weekly bonus from the opening example. Straight-time wages are $900 and the bonus is $100, so the numerator is $1,000 across the same 45 worked hours.
Dividing that remuneration by the worked hours produces an unrounded regular rate of $22.222…, not the stated wage. The five overtime hours receive an additional premium equal to half of that unrounded rate, computed before rounding, which comes to $55.56.
- Straight time for 45 hours
- $900.00
- Nondiscretionary weekly bonus
- + $100.00
- Regular-rate numerator
- $1,000.00
- Hours actually worked
- 45
- Unrounded regular rate
- $22.222… per hour
- 5-hour additional half-time premium
- $55.56
- Total pay for the week
- $1,055.56
The regular rate is rounded here only for display. The premium is computed from the unrounded rate, then rounded to cents.
The shortcut fails because it prices the five overtime hours from the wage alone, then places the bonus beside that calculation as though it could not affect the rate. That sequence yields the lower total from the opening. The FLSA sequence is different: put the includable bonus into remuneration, divide by hours worked, and only then compute the overtime premium.
Calling a payment a bonus does not by itself settle its treatment. The calculator’s classification guide follows 29 CFR 778.211(c) for nondiscretionary bonuses and §778.211(d) for the limits of an employer-applied “discretionary” label. A genuinely discretionary bonus is among the statutory exclusions; a nondiscretionary bonus belongs in remuneration.
Two straight-time rates produce a weighted average
The same distinction appears without a bonus when one employee works at two straight-time rates in the same workweek. The federal regular rate is the weighted average of those rates, not whichever rate appears most often and not automatically the rate attached to the overtime hours.
Take a week in which 30 hours are paid at $20 an hour and the remaining 15 at $16. The first block contributes $600 in straight-time remuneration and the second $240.
- 30 hours at $20 an hour
- $600.00
- 15 hours at $16 an hour
- $240.00
- Straight-time remuneration
- $840.00
- Unrounded regular rate
- $18.666… per hour
- 5-hour additional half-time premium
- $46.67
- Total pay
- $886.67
The premium is computed from half of the unrounded weighted-average rate. The displayed rate is not multiplied back out.
This example shows why “What is your hourly rate?” may not provide enough information. When two rates apply, the regular-rate numerator holds the straight-time earnings from both. The divisor holds all hours actually worked. Only after those amounts are combined does the overtime rate emerge.
The same average-hourly-rate structure applies when pay is based on piece rates, a salary, commissions, or another basis. Under the Department of Labor’s stated method, total pay less the statutory exclusions is divided by hours actually worked. Whatever the pay basis, the resulting regular rate cannot be less than the applicable minimum wage.
Overtime belongs to a fixed workweek
The federal trigger is not a weekend shift or the total on a multiweek paycheck. It is more than 40 hours in one workweek for a covered, non-exempt employee.
A workweek is a fixed and regularly recurring period of 168 hours: seven consecutive periods of 24 hours. It does not have to match a calendar week. It may begin on any day and at any hour, and an employer may establish different workweeks for different employees.
“Fixed” is the important word. Once the recurring workweek identifies which hours belong together, each week receives its own federal overtime test. The Department of Labor expressly says that averaging hours over two or more weeks is not permitted.
That is why “I worked 30 hours, then 50, so I averaged 40” does not answer the federal question. The two workweeks cannot be merged into one average. Each fixed workweek stands on its own, even when both appear in the same pay period.
Federal law also places no general limit on the number of hours an employee aged 16 or older may work. The FLSA rule described here is a pay requirement for covered, non-exempt work after the weekly threshold, not a general maximum-hours rule for that age group.
Weekends and holidays do not create federal overtime by themselves
Fact Sheet #23 is equally direct about timing that does not trigger the premium. The FLSA does not require overtime pay merely because work occurs on a Saturday, Sunday, holiday, regular day of rest, or another particular day.
Those hours still belong in the fixed workweek and can contribute to crossing 40. Their place on the calendar does not, by itself, make them overtime hours under the federal rule. A Saturday hour is tested like another worked hour in that workweek; it becomes part of the federal overtime calculation when the weekly total crosses the threshold, not because its name is Saturday.
Holiday time creates a second distinction. Pay for a period when no work is performed, including qualifying vacation, holiday, or illness pay, is among the listed exclusions from the regular rate. Actual hours worked on a holiday remain worked hours, but the holiday label alone does not create the federal premium. Our federal holidays guide covers the separate question of statutory holidays, observed days off, and private-employer holiday policies.
An employer’s own plan may promise weekend or holiday premium pay, and state law may require more. 29 U.S.C. §218(a) is explicit that nothing in the FLSA excuses noncompliance with a state law setting a maximum workweek lower than the federal one, which is what lets a state add a daily trigger the federal rule has no equivalent for.
California is the clearest case. Labor Code §510 requires time and a half after eight hours in a workday and double time after twelve, on top of the weekly test. Those sources still matter, but they do not change what the general federal rule itself requires “as such.”
Included pay and excluded pay must stay separate
The regular rate begins broadly with remuneration, then removes payments that satisfy a statutory exclusion. That order is safer than beginning with the wage and adding only whatever happens to look wage-like.
Common included amounts in the calculator’s verified table are base hourly wages, a night-shift differential, and a promised production or attendance bonus that is nondiscretionary. A second straight-time rate also enters through the weighted-average calculation. Each changes, or helps form, the remuneration divided by worked hours.
The Department of Labor’s verified exclusion list includes qualifying expense reimbursements, true overtime, weekend, or holiday premiums, discretionary bonuses, gifts, and pay for periods when no work is performed because of vacation, holiday, or illness. 29 U.S.C. §207(h) and 29 CFR 778.202 also address the treatment and crediting of qualifying premium payments.
The word “qualifying” matters. This article cannot classify a particular reimbursement, bonus, gift, or premium from its name alone. The calculator’s reference table is a starting guide to the general treatment and controlling provisions, not a determination for a compensation plan.
Do
- Start with all remuneration for the workweek, then apply the statutory exclusions.
- Include a night-shift differential and a nondiscretionary weekly bonus in the regular-rate calculation.
- Combine two straight-time rates through the weighted-average method.
- Test every fixed workweek separately.
Don't
- Assume the stated hourly wage is always the regular rate.
- Treat a payroll label as proof that a bonus is discretionary.
- Average hours across two or more workweeks.
- Assume Saturday, Sunday, holiday, or rest-day work automatically earns a federal premium.
Use the federal result as a floor, not a personal determination
This guide states the general federal method for covered, non-exempt employees. It does not determine whether a particular employee is covered or exempt, whether a payment satisfies an exclusion, or how a state rule applies to a particular schedule.
Check the employer’s fixed workweek, the actual terms of every payment, the employer’s pay plan, and any applicable state law. A state can require more than the federal weekly rule, including daily overtime or a different threshold, and an employer’s own plan can promise premium pay that the FLSA does not require by itself.
The durable sequence is simple. Identify the fixed workweek. Total the hours actually worked. Classify the remuneration under the federal inclusions and exclusions. Divide included straight-time remuneration by worked hours to obtain the regular rate. Then add the half-time premium for hours over 40 because straight time for those hours is already present.
If extra pay exists, do not reach for one and one-half times the wage as the first step. Build the regular rate first. That is the difference between a familiar shortcut and the federal calculation the words “time and a half” actually describe.
