Half-Time Premium: Simple Overtime Guide

A Super-Simple Guide for Small Business Owners

If your employees earn commissions or bonuses and also work overtime, federal rules from the U.S. Department of Labor may require you to pay an extra amount called the half-time premium. Here is the simplest possible explanation without overcomplicating anything.

1. Discretionary vs. Non-Discretionary Bonuses

Discretionary Bonus (NOT included in overtime)A discretionary bonus is a true surprise, not promised ahead of time, and given at the employer’s sole discretion.Examples: unexpected holiday bonus, random appreciation bonus, one-time reward with no prior mention.

Non-Discretionary Bonus (MUST be included in overtime)A non-discretionary bonus is promised or expected and tied to performance, sales, production, attendance, or goals. Examples: sales commissions, safety bonuses, attendance bonuses, production bonuses, anything promised in writing or verbally.

2. Why Non-Discretionary Bonuses Must Be Included

Overtime must be based on the employee’s regular rate of pay, which must include non-discretionary bonuses and commissions. These increase their actual earnings, so the overtime amount must be adjusted.

3. Federal Overtime Rule

Employees who work over 40 hours in a workweek must receive overtime at 1.5 × the regular rate of pay. Because straight-time pay has already been paid for all hours (including overtime hours), only the extra half is still owed. Half-Time Premium Formula: 0.5 × Regular Rate × Overtime Hours

4. What the DOL Calls This Overtime Adjustment

When bonuses or commissions change the regular rate, the DOL requires payment of the Half-Time Premium for Overtime Hours. This is the extra half of overtime pay owed after recalculating the regular rate to include bonuses or commissions. Plain English: you already paid the straight-time portion, so now you add the extra half to complete overtime.

5. Bonus/Commission Must Tie to the Same Workweek

The half-time premium applies only when the overtime hours and the non-discretionary bonus or commission were earned in the same work week. If a bonus covers multiple weeks (like a monthly commission), it must be allocated correctly across the weeks it applies to.

6. Simple Real-World Examples

Example 1: Weekly Commission

Hourly rate: $20

Hours worked: 50 (10 overtime)

Commission: $200

Total earnings: 40×20 = 800; 10×20 = 200; +200 commission = 1,200

Regular rate: 1,200 ÷ 50 = 24

Half-time premium: 0.5×24×10 = 120

Total pay: 1,320

Example 2: Non-Discretionary Production Bonus

Hourly rate: $18

Hours worked: 45 (5 overtime)

Bonus: $100

Total earnings: 40×18 = 720; 5×18 = 90; +100 bonus = 910

Regular rate: 910 ÷ 45 = 20.22

Half-time premium: 0.5×20.22×5 = 50.55

Total pay: 960.55

When It Does Not Apply

No half-time premium is owed when the bonus is discretionary, cannot be tied to a specific week, or is paid quarterly/annually without a week-level breakdown.

7. Why You Can’t “Let It Slide”: Real-World Consequences

Even small payroll mistakes involving the half-time premium can become expensive.

A. Back Wages for Up to 3 Years - The employer may be required to repay all unpaid overtime adjustments across up to three years and for all affected employees.

B. Liquidated Damages - Amounts owed can be doubled through liquidated damages.

C. Civil Money Penalties - Repeated or serious issues can trigger fines.

D. Attorney Fees - In wage disputes, employers may end up paying both their legal fees and the employee’s legal fees.

E. Increased Scrutiny - Payroll practices, timekeeping, and worker classification may receive more attention going forward.

F. Reputation and Trust Issues - Payroll errors spread quickly among employees and damage morale.

8. Key Things to Remember

Non-discretionary bonuses and commissions must be included in the regular rate. The correct overtime adjustment is the half-time premium. Regular rate calculations must include all non-discretionary pay. Bonuses must relate to the same work week. Documentation matters. State laws may be stricter than federal law.
