DOL Overtime Calculator: How to Use It

The DOL overtime calculator helps you figure out overtime pay under the U.S. Fair Labor Standards Act (FLSA). You enter an employee’s regular hourly rate and the number of overtime hours worked in a workweek, and it returns the overtime pay due at the required time-and-a-half rate.

Formula

The FLSA requires overtime pay of at least 1.5 times the employee’s regular rate for all hours worked over 40 in a workweek. The basic formula is:

Overtime Pay = Regular Hourly Rate × 1.5 × Overtime Hours

Where:

• Regular Hourly Rate – the employee’s standard hourly wage (in dollars per hour).
• 1.5 – the FLSA overtime multiplier (time-and-a-half).
• Overtime Hours – the number of hours worked beyond 40 in a single workweek.

For example, if an employee earns $20 per hour and works 45 hours, the overtime pay is $20 × 1.5 × 5 = $150. That $150 is in addition to the regular pay for 40 hours ($800), making total gross pay $950.

Worked Example

Using the calculator defaults: regular rate = $20.00, overtime hours = 5.

1. Multiply the regular rate by 1.5: $20.00 × 1.5 = $30.00 (overtime rate per hour).
2. Multiply the overtime rate by the number of overtime hours: $30.00 × 5 = $150.00.
3. For the total pay for overtime hours, add the straight-time pay for those hours ($20 × 5 = $100) to the overtime premium ($150) = $250.00.

The calculator shows overtime pay of $150.00 and total pay for those 5 hours of $250.00.

When to Use the DOL Overtime Calculator

Use this calculator when you need to determine overtime pay for a non-exempt employee under federal law. It’s most useful for:

• Payroll processing for hourly workers who exceed 40 hours in a week.
• Estimating labor costs for a project that may require overtime.
• Checking a pay stub to verify overtime was calculated correctly.
• Planning budgets for overtime-heavy periods like holidays or end-of-month rushes.

The calculator assumes a standard 40-hour workweek, which is the FLSA threshold. Some states have daily overtime rules (e.g., after 8 hours in a day) or require double time for certain hours; this calculator does not account for those variations.

How to Read the Results

The first output, Overtime Pay, is the extra amount owed for the overtime hours. The second output, Total Pay for Overtime Hours, is the sum of the straight-time pay for those hours plus the overtime premium. The distinction matters because some employees mistakenly think they only get the premium, but they also get their regular hourly wage for those hours.

For example, an employee who works 45 hours at $20/hour earns $800 for the first 40 hours plus $150 for the 5 overtime hours, totaling $950. The $150 is the overtime premium; the $100 straight-time for those 5 hours is already included in the $950 total.

Common Mistakes and Misconceptions

One frequent error is using the wrong base rate. Overtime is based on the regular rate, which includes most bonuses, commissions, and piece-rate earnings, not just the base hourly wage. For instance, if an employee earns $18/hour plus a $50 production bonus in a 50-hour week, the regular rate is ($18 × 50 + $50) ÷ 50 = $19/hour, so overtime is $19 × 1.5 × 10 = $285.

Another mistake is rounding hours incorrectly. The FLSA requires overtime to be paid for each hour over 40; partial hours must be counted. If an employee works 40 hours and 30 minutes, the overtime is 0.5 hours, not zero.

A common misconception is that salaried employees are always exempt. In fact, many salaried workers are non-exempt and entitled to overtime if they earn below a certain salary threshold or perform non-exempt duties. The DOL’s salary threshold changes periodically, so check current rules.

Limits of This Calculator

This calculator only handles the simple case: a single hourly rate and a single overtime rate. It does not cover:

• Multiple pay rates (e.g., different rates for different jobs in the same week).
• Bonuses or commissions that must be included in the regular rate.
• State-specific overtime rules (e.g., daily overtime, double time, or different thresholds).
• Exempt vs. non-exempt classification.
• Overtime for tipped employees or those paid on a salary basis.

For those situations, you need a more detailed calculation or advice from a labor law professional. The DOL’s official Fact Sheets and the Wage and Hour Division provide authoritative guidance.

Frequently Asked Questions

Q: What is the current federal overtime rate?
The FLSA requires overtime at 1.5 times the regular rate for hours over 40 in a workweek. Some states have different rates (e.g., double time for certain hours), but 1.5 is the federal minimum.

Q: Do I need to pay overtime for weekly hours over 40 or daily over 8?
Federal law only requires overtime for hours over 40 in a workweek. Some states (like California) require daily overtime after 8 hours, but this calculator follows the federal rule. Check your state’s labor department for daily rules.

Q: How do I calculate overtime if the employee gets a bonus?
Bonuses that are nondiscretionary must be included in the regular rate. Add the bonus to total earnings, divide by total hours worked, then use that as the regular rate for overtime. For example, a $100 bonus in a 50-hour week adds $2 to the regular rate ($100 ÷ 50).

Q: Are salaried employees ever entitled to overtime?
Yes. Salaried employees are entitled to overtime if they are non-exempt. The DOL sets a salary threshold (currently $684 per week as of 2020) and duties tests. If the salary is below the threshold or the duties are not executive, administrative, or professional, the employee must receive overtime.

Q: Can an employer give comp time instead of overtime pay?
In the private sector, no. The FLSA requires cash overtime pay at 1.5 times the regular rate. Public sector employers may offer compensatory time off under certain conditions, but private employers cannot substitute comp time for overtime pay.

Q: What if the employee works overtime but is not authorized?
Under the FLSA, the employer must pay for all hours worked, even if the overtime was not authorized. The employer can discipline the employee, but cannot withhold the overtime pay.
