How Overtime Pay Is Calculated

Overtime Pay = Overtime Hours × Hourly Rate × Overtime Multiplier

Under the basic federal rule, covered nonexempt employees generally receive overtime at no less than 1.5 times the regular rate after 40 hours in a fixed workweek. This estimate does not average hours across weeks or treat weekend and holiday work as automatic overtime.

What Is Overtime Pay?

Overtime pay is additional compensation for eligible employees who work beyond the overtime threshold. Under the basic federal rule, eligible overtime is paid at no less than 1.5 times the regular rate.

Some employees may be exempt from federal overtime requirements, and state or local laws may provide greater protections. Payroll teams should verify job classification, plan rules, and applicable law.

Regular Rate vs Base Hourly Rate

The base hourly rate is an employee's standard rate of pay. The regular rate can include eligible nondiscretionary bonuses and shift differentials, which may change the overtime premium. Complex compensation arrangements may require payroll or legal review.

Frequently Asked Questions

When does federal overtime begin?

For covered, nonexempt employees, federal overtime generally begins after 40 hours worked in a fixed workweek. This calculator uses that threshold by default.

Is weekend or holiday work automatically overtime?

No. Federal overtime is generally based on hours worked in a workweek, not the day of the week. Saturday, Sunday, holiday, or rest-day work is not automatically overtime under the federal rule.

Can I average hours across two weeks?

No. Federal overtime is calculated separately for each fixed workweek. This calculator does not average hours across two or more weeks.

What is the regular rate?

The regular rate can include eligible compensation such as nondiscretionary bonuses and shift differentials. The advanced mode estimates the regular rate using the compensation you enter.

Does this calculate taxes or take-home pay?

No. It estimates gross earnings only and does not calculate taxes, deductions, benefits, or net pay.

Do state laws use the same overtime rule?

Not always. State and local rules may provide greater worker protections. This first version estimates the federal rule and does not calculate state or local overtime requirements.
