What Is the Regular Rate of Pay? How to Calculate It for Overtime

Ask most employees what their “regular rate of pay” is, and they’ll say their hourly wage. Ask many payroll operators the same question, and you’ll get a similar answer. Both are often wrong — and that gap between the assumed rate and the actual rate is one of the most common sources of overtime underpayment under the FLSA.

The regular rate of pay is a specific legal term. Under the Fair Labor Standards Act, it is not simply your hourly wage or your salary equivalent. It is the total straight-time compensation an employee earns in a workweek, divided by total hours worked — and it must include most forms of additional compensation beyond base pay.

This guide explains what the regular rate includes, what it excludes, how to calculate it when bonuses or commissions are involved, and why getting it wrong reliably leads to underpaid overtime.

What “Regular Rate of Pay” Really Means

The FLSA requires employers to pay overtime at 1.5 times an employee’s regular rate — not 1.5 times the base wage. The regular rate is defined in FLSA § 7(e) as all remuneration for employment in a workweek, with certain specific exclusions. The formula is straightforward:

The key phrase is “total straight-time pay.” If an employee earns anything beyond their base wage in the same workweek — a production bonus, a commission, a shift differential — that extra pay generally must be counted before dividing by hours. Using only the base wage as the denominator underestimates the regular rate and underpays overtime.

What Counts in the Regular Rate

Payments that are included

The FLSA takes a broad, inclusive approach. All remuneration for employment is included unless it falls into one of eight specific exclusions listed in § 7(e). Common forms of pay that must be included:

• Non-discretionary bonuses: Any bonus tied to performance criteria, productivity, attendance, safety, or quality set in advance. If the criteria are announced before the work is done, the bonus is non-discretionary and must be included. The DOL reaffirmed this in Opinion Letter FLSA 2026-2, issued January 5, 2026.
• Shift differentials: Extra pay for night shifts, weekend shifts, or other premium-rate shifts that compensate for undesirable hours (not for overtime itself).
• Commissions: Sales commissions earned during a workweek are part of total compensation and must be allocated to the hours worked to find the regular rate. This may require a retroactive adjustment once commissions are finalized.
• Most incentive pay: Piece-rate earnings, on-call pay, waiting time pay — all forms of compensation tied to work performed or time available.

Payments that are excluded

The following types of pay may be excluded from the regular rate — but only if they genuinely meet the conditions in FLSA § 7(e). The exclusions are specific and narrow:

• True gifts: Holiday bonuses or gifts that are not tied to hours, production, or efficiency, and are entirely at the employer’s discretion.
• Purely discretionary bonuses: Must meet the full discretionary standard — both the fact and amount decided solely by the employer, at or near the end of the period, with no prior promise or plan.
• Expense reimbursements: Payments that reimburse actual, reasonable business expenses (travel, meals, tools).
• Premium pay for overtime already computed: The extra half-time premium itself is not re-counted in the regular rate.
• Certain benefit plan contributions: Employer contributions to qualifying profit-sharing, thrift, or savings plans meeting specific FLSA criteria (29 C.F.R. § 778.214).

Worked Examples

Example 1 — Hourly employee with a weekly production bonus

Maria earns $16.00/hour and worked 45 hours this week. Her employer paid a $100 nondiscretionary production bonus (tied to units completed).

Example 2 — Salaried non-exempt employee with a nondiscretionary bonus

David is a salaried non-exempt employee earning $900/week (treated as a 40-hour salary). He worked 48 hours this week and received a $150 quarterly safety bonus allocated to this pay period.

Note: When bonus amounts cover multiple workweeks (e.g., a quarterly bonus), the regular rate adjustment method may differ. 29 C.F.R. § 778.209 describes how to allocate bonus amounts that span more than one pay period. This general information does not substitute for professional guidance on specific payroll situations.

Why Regular Rate Errors Break Overtime

Most overtime underpayment cases don’t result from an employer paying 0% overtime. They result from an employer calculating overtime on a rate that’s slightly too low — usually because a weekly bonus, commission, or shift differential wasn’t folded into the base wage before the math was done.

The consequence compounds over time. A $5 per week regular-rate error on one non-exempt employee’s overtime calculation can add up to hundreds or thousands of dollars in back wages over months. Multiplied across a workforce, the exposure grows quickly — and the FLSA allows employees to recover back wages for up to two years (three years for willful violations).

The January 2026 DOL Opinion Letter (FLSA 2026-2) reinforced that even performance-based bonus plans with judgment criteria — such as whether a task was completed to standard — do not convert a nondiscretionary bonus into a discretionary one. Employers with planned bonus programs should review whether those bonuses are being included in overtime calculations.

Common Mistakes to Avoid

• ✗ Using base hourly rate only. If an employee receives any additional compensation during an overtime week — a bonus, a commission, a shift differential — the overtime calculation must account for it. Using only the base wage understates the regular rate.
• ✗ Labeling bonuses "discretionary" without meeting the standard. Announcing a bonus plan in advance eliminates discretion, even if the exact amount varies. Any bonus tied to criteria set before the work was done is almost certainly nondiscretionary. The 2026 DOL opinion letter made this explicit.
• ✗ Forgetting to recalculate when pay components change. The regular rate is a weekly calculation. Any week an employee’s compensation includes more than their base wage — a bonus, an extra shift at a different rate — the regular rate must be recalculated for that week.
• ✗ Ignoring commissions in overtime weeks. Commission earnings must be included in the regular rate for the workweek in which they are earned (or allocated). If a commission covers multiple weeks, the employer must use the allocation method in 29 C.F.R. § 778.119.
• ✗ Assuming "no prior promise" is easy to establish. If employees were informed of a bonus plan — even informally — the employer may have already abandoned discretion. The DOL applies a facts-and-circumstances test, and announced plans nearly always fail the discretionary-bonus exclusion.
