The Regular Rate of Pay: The Number Behind Every Overtime Calculation

Almost every overtime mistake traces back to one number: the regular rate of pay. Employers assume it is the wage printed on the offer letter, multiply by 1.5, and move on. But under the FLSA the regular rate is a calculated figure that must fold in most of what an employee earns — and getting it wrong underpays overtime on every affected check. This is the concept the rest of wage-and-hour law is built on.

What the regular rate actually is

The regular rate is defined in 29 CFR §778.108 as the total remuneration paid to an employee in a workweek, divided by the total number of hours actually worked. It is an hourly figure, even for salaried non-exempt employees, and it is calculated per workweek — it can change from one week to the next as pay and hours change.

regular_rate = total_remuneration_for_the_week ÷ total_hours_worked

The phrase doing the work there is "total remuneration." It is much broader than base wages.

What must be included

Under 29 CFR §778.208–§778.210, the regular rate must include nearly all forms of compensation tied to the work:

Included in the regular rate	Why
Hourly wages	Base pay
Non-discretionary bonuses	Promised or expected — production, attendance, safety
Shift differentials	Extra pay for undesirable shifts
Commissions	Paid for sales performance
Piece-rate earnings	Pay tied to output
On-call pay	Compensation for restricted time
Retroactive pay increases	Allocated back to the weeks worked

The most common omission is the non-discretionary bonus. If an employer promises a $200 bonus for hitting a production target, that $200 is part of the regular rate for the weeks it was earned. Spreading it across the hours raises the rate, which raises the overtime premium. Paying overtime on the base wage alone, ignoring the bonus, underpays the employee — the single most frequent regular-rate error in DOL investigations.

What can be excluded

29 CFR §778.200–§778.224 lists the statutory exclusions. These may be left out of the regular rate:

• Discretionary bonuses — where both the fact and the amount are decided at the employer's sole discretion, with no prior promise
• Gifts on special occasions, not measured by hours or production
• Paid time off — vacation, holiday, and sick pay for hours not worked
• Expense reimbursements — travel, tools, and similar
• Premium pay already paid for daily or weekend overtime, in some cases
• Employer contributions to bona fide benefit plans

The exclusions are read narrowly. A "discretionary" bonus that employees have come to expect, or that follows a known formula, is not actually discretionary and cannot be excluded.

Worked example: an hourly employee with a bonus

An employee earns $18/hr, works 45 hours, and receives a $90 non-discretionary production bonus that week.

1. Straight-time earnings: $18 × 45 = $810
2. Add the bonus: $810 + $90 = $900 total remuneration
3. Regular rate: $900 ÷ 45 = $20.00/hr
4. Overtime premium: the extra half-time on the 5 OT hours is $20 × 0.5 × 5 = $50
5. Total pay: $900 + $50 = $950

Note the bonus pushed the regular rate from $18 to $20 — so the overtime is figured on $20, not $18. Our FLSA Overtime Calculator performs exactly this calculation, including the bonus step.

Salaried non-exempt employees

For a non-exempt employee paid a fixed salary, the regular rate is the salary divided by the hours it is intended to cover. If a $760 weekly salary is meant to cover 40 hours, the regular rate is $19/hr, and overtime is owed on top at 1.5× for hours past 40. If the salary is instead understood to cover all hours in a fluctuating schedule, the fluctuating workweek method and its 0.5× premium may apply. Either way, the regular rate is the starting point.

Employees who work at two or more rates

When an employee performs different jobs at different rates in the same week, the regular rate is the weighted average of those rates (29 CFR §778.115) — total straight-time earnings divided by total hours. It is not the higher rate, and not the simple average of the two. Our Blended Overtime Calculator handles this case.

Why this matters so much

Because the regular rate feeds every overtime calculation, an error in it repeats on every paycheck and across every affected employee. Combined with the FLSA's two- or three-year lookback and mandatory liquidated damages, a small per-hour understatement becomes a large liability. If you suspect overtime was computed on the base wage rather than the true regular rate, our Back Pay Calculator can size the exposure.

Key takeaways

• The regular rate is calculated, not assumed — total pay ÷ hours worked, per workweek.
• It must include non-discretionary bonuses, shift differentials, commissions, and most other earnings.
• Only the specific statutory exclusions may be left out, and they are read narrowly.
• Overtime is always 1.5× (or 0.5× under the fluctuating workweek) of the regular rate, never automatically the base wage.
