Overtime Pay Calculator US – FLSA-Compliant Weekly Pay Tool
Overtime Pay Calculator US – Overtime pay plays a critical role in the income of millions of workers across the United States. Yet despite its importance, overtime wages are one of the most misunderstood and frequently miscalculated parts of payroll. The Fair Labor Standards Act (FLSA) sets clear federal rules on when overtime applies, how it must be calculated, and who is eligible to receive it.

How Overtime Pay Works Under FLSA
The Fair Labor Standards Act requires that non-exempt employees receive overtime pay at no less than one and one-half times their regular rate of pay for all hours worked over 40 in a single workweek. The law applies regardless of how many hours are worked in a single day.
Who Qualifies for Overtime Pay
Most hourly workers qualify for overtime protection, but not all employees are covered. Some salaried employees are classified as exempt based on salary level, job duties, and industry. Misclassification is a common issue and can result in unpaid wages over time.
Common Overtime-Eligible Jobs
Retail associates, healthcare workers, warehouse employees, delivery drivers, manufacturing staff, and many service-based roles typically qualify for overtime pay under federal law.
Why Overtime Pay Errors Are Common
Overtime mistakes often happen because employers miscalculate regular rates, exclude bonuses improperly, or misunderstand eligibility rules. Even small errors can add up to thousands of dollars in lost income over a year.
Federal Labor Law Reference
Official overtime guidance is maintained by the U.S. Department of Labor. You can review detailed protections and enforcement rules directly from the Wage and Hour Division.

Understanding Regular Pay vs Overtime Pay in the US
Many employees often confuse regular pay with overtime pay, especially when work hours increase. However, under the Fair Labor Standards Act (FLSA), these two wage types follow very different rules. Therefore, understanding the difference helps you verify your paycheck and avoid underpayment.
In simple terms, regular pay applies to the first 40 hours you work in a standard workweek. Meanwhile, overtime pay applies only after you cross that limit. As a result, overtime earnings grow faster because employers must pay a higher hourly rate.
Key Differences Between Regular Pay and Overtime Pay
To make things clearer, the table below compares regular pay and overtime pay side by side. This comparison helps you quickly identify how your wages change once overtime begins.
| Category | Regular Pay | Overtime Pay |
|---|---|---|
| Applicable Hours | Up to 40 hours per week | More than 40 hours per week |
| Pay Rate | Standard hourly wage | 1.5× the regular hourly rate |
| Legal Requirement | Mandatory for all worked hours | Mandatory under FLSA (for non-exempt employees) |
| Typical Use Case | Normal weekly schedule | Extra shifts, extended hours, urgent deadlines |
| Calculation Method | Hourly rate × hours worked | Hourly rate × 1.5 × overtime hours |

Overtime Pay Calculator – Frequently Asked Questions
How does overtime pay work under U.S. labor law?
Under the Fair Labor Standards Act (FLSA), employers must pay eligible employees overtime wages when they work more than 40 hours in a single workweek. As a result, workers earn at least 1.5 times their regular hourly rate for overtime hours. Moreover, this rule applies nationwide unless a specific exemption applies.
Is overtime calculated daily or weekly?
Importantly, U.S. employers calculate overtime on a weekly basis, not daily. Therefore, working long shifts on individual days does not automatically trigger overtime pay unless your total weekly hours exceed 40. However, some states and union contracts follow stricter daily overtime rules.
Who qualifies for overtime pay?
Most hourly employees qualify for overtime pay. In contrast, certain salaried workers fall under exempt categories based on job duties and salary thresholds. Consequently, misclassification often causes unpaid overtime issues, which makes understanding eligibility extremely important.
Does overtime pay get taxed differently?
In practice, the IRS taxes overtime pay the same way it taxes regular wages. However, overtime pay may temporarily increase tax withholding because the paycheck amount appears higher. Ultimately, your annual tax liability remains based on total income.
Can employers offer double-time pay?
Yes, some employers offer double-time pay for extended overtime hours, holidays, or specific industries. For example, certain healthcare and manufacturing roles receive higher multipliers. Nevertheless, federal law requires only time-and-a-half unless state laws specify otherwise.
Why should I use an overtime pay calculator?
Simply put, overtime calculations often confuse workers. Therefore, this overtime pay calculator helps you estimate earnings accurately, verify paychecks, and plan monthly finances more confidently. Additionally, it allows you to spot underpayment issues early.
