Federal employee overtime pay basics

What this calculation answers

A federal employee overtime calculation answers how many hours qualify as overtime, which rule controls the rate, and what gross overtime pay should be reviewed. The first input is FLSA status, recorded on Standard Form 50, box 35 as N for nonexempt or E for exempt. Actual duties control that status, not the job title alone.

For FLSA-nonexempt federal employees, OPM applies one and one-half times the hourly regular rate for hours of work over 8 in a day or 40 in a fixed 168-hour workweek, subject to listed federal exceptions. FLSA-exempt covered employees generally use title 5 overtime rules for officially ordered or approved work above 8 hours in a day or 40 hours in an administrative workweek.

Start with federal status

Do not calculate federal overtime from the job series alone. A GS employee, wage employee, law enforcement employee, firefighter, or other federal worker can fall under different overtime treatments. SF-50 box 35 gives the FLSA category, while the pay authority and duty rules decide whether FLSA overtime, title 5 overtime, or a special rule applies.

Title 5 adds caps that do not apply to FLSA overtime or prevailing-rate wage employees. For covered FLSA-exempt title 5 employees, overtime at or below GS-10, step 1 is 1.5 times the basic hourly rate. Above GS-10, step 1, the rate is capped at the greater of 1.5 times the GS-10, step 1 hourly rate or the employee's own basic hourly rate.

Run the pay formula

For FLSA overtime, OPM computes pay as straight-time pay for all overtime hours plus one-half of the hourly regular rate for those overtime hours. The hourly regular rate is total remuneration in the workweek divided by the hours for which it is paid, including applicable locality pay or special rate supplements.

Assume a federal FLSA-nonexempt employee earns a $31.20 hourly regular rate, including applicable rate supplements, and works 10 hours Monday, 9 Tuesday, 8 Wednesday, 8 Thursday, and 7 Friday. Total paid hours are 42, and daily overtime is 3 hours. Straight-time pay is 42 × $31.20 = $1,310.40. The extra half-time premium is 3 × $15.60 = $46.80, so gross pay is $1,357.20.

Move from check to record

A one-off calculation is enough when you need to verify a single timesheet, test a rate, or explain why daily hours changed the overtime count. It is not enough when overtime repeats across pay periods, employees use comp time, or title 5 caps must be reviewed against premium-pay limits.

Federal payroll review needs an approved record of hours, status, and exceptions. Everhour Reporting can surface overtime data in Team Hours and custom reports, then group, filter, export, or schedule those reports for review. That workflow is especially useful when managers need to compare approved time with payroll inputs without rebuilding the calculation by hand.

Frequently Asked Questions

Which federal overtime rule applies first?

Start with the employee's FLSA category on SF-50 box 35 and the actual duties behind that status. FLSA-nonexempt federal employees use OPM's FLSA overtime calculation. FLSA-exempt covered employees generally use title 5 overtime rules for officially ordered or approved work. Special groups, including federal firefighters covered by 5 U.S.C. 5545b, use separate thresholds.

How are daily and weekly federal overtime thresholds counted?

For federal FLSA-nonexempt employees, overtime applies after 8 hours in a day or 40 hours in a fixed 168-hour workweek, subject to listed federal exceptions. Title 5 also covers officially ordered or approved work above 8 hours in a day or 40 hours in an administrative workweek for covered FLSA-exempt federal employees. Do not average workweeks to avoid overtime.

Does locality pay belong in the federal FLSA regular rate?

Yes, for FLSA overtime, the hourly regular rate is total remuneration in the workweek divided by the hours for which it is paid, including applicable locality pay or special rate supplements. Excluding those supplements understates the regular rate and the half-time premium used in OPM's FLSA overtime calculation.

Can federal comp time replace overtime pay?

Federal compensatory time off is granted hour-for-hour for overtime and generally must be used within 26 pay periods. Unused FLSA-nonexempt comp time must be paid at the overtime rate in effect when earned. FLSA overtime cannot be waived by agreement, and comp-time treatment depends on the employee category and governing rule.

Are on-call hours counted for federal overtime?

Standby time counts as hours of work when official restrictions are so substantial that the employee cannot use the time personally. Ordinary on-call time with a phone or electronic device and a reasonable call-back radius is off duty. The mistake is treating every on-call rotation as paid work without checking the actual restrictions.

How does Everhour report federal employee overtime review data?

Everhour Reporting provides customizable reports with 45+ columns, grouping, filters, date ranges, exports, and scheduled email delivery. When overtime tracking is enabled, overtime and double-overtime data can appear in Team Hours and configurable reports for manager review before payroll handoff.

How can Everhour approvals support federal timesheet review?

Everhour Timesheets let users submit weekly project hours or working hours, then managers can approve, reject, or partially approve submitted time. Submitted and approved time is protected from regular member edits, which helps preserve the reviewed record used for payroll or billing checks.

Keep overtime records reviewable

Turn one-off federal overtime checks into recurring review reports. Everhour Reporting keeps approved overtime visible by person, project, date range, and export format for cleaner payroll handoff.
