Bonus or Shift Differential Left Out of Your Overtime Pay? The Regular Rate Rules: key takeaways
A visual summary of this post's main points. Read the article for context and limits.
Key point 1
Overtime under the FLSA is at least one and one-half times your regular rate of pay, which is not always the same as your base hourly wage
Key point 2
Nondiscretionary bonuses, such as attendance, production or retention bonuses promised in advance, generally must be included in the regular rate
Key point 3
Shift differentials and other extra pay for working certain hours generally count toward the regular rate
Overtime is not simply 1.5 times your base hourly wage. Under the FLSA, it is at least one and one-half times your regular rate of pay, and that rate can be higher than your base wage when you also earn certain bonuses or extra pay.

Key takeaways
Overtime under the FLSA is at least one and one-half times your regular rate of pay, which is not always the same as your base hourly wage
Nondiscretionary bonuses, such as attendance, production or retention bonuses promised in advance, generally must be included in the regular rate
Shift differentials and other extra pay for working certain hours generally count toward the regular rate
Truly discretionary bonuses, where the employer decides both whether and how much to pay at or near the end of the period, can be left out
What the Regular Rate Is
The 29 CFR 778.109 regular rate is generally all pay for the workweek, with certain statutory exclusions, divided by the hours actually worked. If you work 45 hours, the extra pay that counts is spread across all 45 hours, and the 5 overtime hours are owed at one and one-half times that figure. Our guide to overtime pay covers who is owed it in the first place.
Pay That Usually Counts
Nondiscretionary bonuses
Attendance, safety, production, quality or retention bonuses that were promised or announced in advance to encourage work generally count. See 29 CFR 778.208.
Shift differentials
Extra hourly pay for night, weekend or holiday shifts is part of what you earn for working, so it generally goes into the regular rate.
Hazard or on-site pay
Added pay for difficult, dangerous or remote assignments generally counts as well.
Production and piece-rate pay
Earnings that rise with output are part of the total used to find your rate.
Bonuses an Employer May Leave Out
A bonus can be excluded only if the employer keeps full discretion over whether to pay it and how much, decides this at or near the end of the period, and made no earlier promise or agreement. 29 CFR 778.211 explains this exception. Calling something a "gift" or "discretionary" does not decide the question; the facts do. Also see DOL Fact Sheet 56C on bonuses.
A Simple Example
Suppose you earn $20 an hour, work 45 hours and were promised a $90 attendance bonus. Straight-time pay is $900 plus the $90 bonus, or $990. Divided by 45 hours, the regular rate is $22. Overtime for the 5 extra hours is half of $22, or $11 more per hour, on top of the straight-time pay already counted. Paying overtime at $30 (1.5 times the base wage) alone would leave out the bonus effect.
Signs Your Overtime May Be Short
Overtime is exactly 1.5 times your base wage
If you also got bonuses or differentials in those weeks, the figure on your pay stub may be too low.
Bonus lines with no overtime adjustment
A bonus paid in a week or period with overtime hours should usually change the overtime owed.
Differentials missing from the overtime rate
Night or weekend premiums that stop applying once you pass 40 hours are worth a closer look.
Bonus rules in writing
Emails, plan documents or handbooks that describe the bonus as earned by meeting set goals suggest it is nondiscretionary.
What to Save
Pay stubs for overtime weeks
Keep stubs showing hours, rates, bonuses and differentials.
Bonus and incentive plans
Handbooks, offer letters, emails and posted announcements describing how the extra pay is earned.
Your hours
Schedules, timesheets or your own daily notes of the hours you worked.
Time Limits and Next Steps
The FLSA generally has a 2-year limit for unpaid overtime, extended to 3 years for willful violations, and state law may give more time. You can contact the Department of Labor or bring a private claim, and it is illegal to retaliate against you for asking. See our guides on recovering unpaid wages and unpaid commissions and bonuses, and time clock rounding for another way hours and pay go missing.
Free Case Review
Whether a bonus or differential should have raised your overtime depends on how it was promised and paid. Our team can review your situation at no cost, if you are eligible.
Do bonuses count toward my overtime rate?
Often yes. Nondiscretionary bonuses promised in advance generally must be included in the regular rate. Truly discretionary bonuses can be excluded.
Do shift differentials increase my overtime pay?
Generally yes. Extra pay for working certain shifts is part of the regular rate used to calculate overtime.
How long do I have to file a claim for underpaid overtime?
The FLSA has a 2-year limit, or 3 years for willful violations. State law may give more time.
