Overtime Pay: How to Calculate Exactly What You're Owed
The FLSA doesn't care about your offer letter, your job title, or your manager's policy. It cares about hours worked and how your pay is structured. Here's the exact formula — including regular rate, bonuses, and state rules — so you can verify every paycheck.
Paycheck lands. Hours worked: 54. Overtime shown: zero. Your manager told you salaried employees don't get overtime. Or that your role is exempt. Or that company policy doesn't pay OT for "unauthorized" hours.
Here's what your manager may not know — or may be hoping you don't: the Fair Labor Standards Act doesn't care about company policy. It doesn't care what your offer letter says. And in many cases, those blanket "you're exempt" claims are flatly wrong. Wage theft through misclassified overtime is one of the most common labor violations in the US, and it happens to white-collar workers just as often as it does on the factory floor.
The Federal Baseline: How FLSA Overtime Works
The Fair Labor Standards Act (FLSA) sets the floor for overtime in the US. The core rule is straightforward: non-exempt employees must receive 1.5 times their regular rate of pay for every hour worked beyond 40 in a workweek.
Not a pay period. Not a month. A workweek — any fixed, recurring period of 168 consecutive hours (seven 24-hour days). Your employer sets the workweek. Once set, it cannot be shifted week-to-week to dodge overtime liability.
What "Regular Rate of Pay" Actually Means
This is where employers — even well-intentioned ones — get it wrong. The regular rate isn't just your base hourly wage. Under the FLSA, it must include:
Shift differentials — extra pay for nights, weekends, or hazardous conditions
Non-discretionary bonuses — production bonuses, attendance bonuses, or any bonus tied to performance metrics that employees reasonably expect
Piece-rate earnings and most commissions
What's excluded: discretionary bonuses decided at the employer's sole discretion with no prior promise, gifts, vacation pay, and certain expense reimbursements.
The most common error: If you earn $20/hour base but receive a weekly $200 production bonus, your regular rate isn't $20 — it's higher. Your overtime must be calculated on the blended figure. Calculating OT only on base wage while excluding the bonus is a violation.
The Overtime Calculation: Step by Step
Maria is a warehouse supervisor earning $22/hour who received a $150 non-discretionary productivity bonus this week and worked 50 hours. Here's exactly how her overtime should be calculated:
Step 4: Total weekly pay$1,250 straight time + $125 OT premium
$1,375.00
The half-time method applies because all 50 hours were already compensated at straight time. Maria's employer owes an additional 0.5× her true regular rate for each of the 10 overtime hours — not 1.5× the base wage on just the OT hours. If the bonus was excluded from the calculation, her regular rate would be artificially low and her overtime underpaid.

Overtime Exemptions: Who Actually Qualifies
To qualify as exempt under the executive, administrative, or professional exemptions, an employee must meet all three of these conditions — not just one:
Test
Requirement
Where It Fails
Salary Basis
Paid a predetermined salary that doesn't vary based on hours worked
Docked pay for partial-day absences, hourly tracking
Salary Level
At least $684/week ($35,568/year) under current federal rules
Earning below this threshold — no exemption regardless of title
Duties Test
Primary duties must involve management, independent judgment on significant matters, or advanced professional knowledge
Title says "manager" but job is mostly non-managerial tasks
Job titles are legally irrelevant. Actual duties determine exemption status. The duties test is where most misclassifications are found — and where the most recoverable wages hide.
Common Misclassification Scenarios
These are the roles most frequently misclassified as overtime-exempt when they're likely not:
Likely non-exempt
Assistant Manager — Retail / Food Service
Often classified as exempt despite spending the majority of their time on non-managerial tasks like stocking, serving, or cashiering. Fails the duties test.
Likely non-exempt
Inside Sales Employee
The outside sales exemption doesn't apply to employees who primarily work from an office or remotely. Physical presence outside is required for that exemption.
Depends on duties
IT / Tech Worker
The computer employee exemption has specific requirements. Not every tech role qualifies — the work must primarily involve systems analysis, programming, or design at a senior level.
Likely non-exempt
Administrative Assistant
The administrative exemption requires genuine exercise of discretion on significant matters — not skilled clerical work performed under close supervision.
Unpaid Overtime: What You Can Recover
If your employer has been miscalculating or withholding overtime, the FLSA provides real remedies:
Recovery Type
Amount
Notes
Back wages
Up to 2 years of unpaid OT
3 years if violation was willful
Liquidated damages
Equal to back wages owed
Effectively doubles your recovery
Attorney's fees & costs
Paid by employer if you win
Many attorneys take these on contingency
State remedies (e.g. CA)
Waiting time penalties + more
Can exceed federal recovery significantly
⚠️ The clock is running: The statute of limitations runs from each pay period where a violation occurred — not from when you discover the problem. If you suspect underpayment, time matters.
How to Document Your Overtime Dispute
You don't need a lawyer to start building your case — but you do need records. Start keeping these now:
Keep
Your Own Time Records
Phone notes, calendar entries, badge swipe logs if accessible. Even informal records carry weight when cross-referenced against employer records. Start logging today — not after you decide to file.
Keep
Every Pay Stub
Save every pay stub for every period in question. Note any weeks where your hours exceeded 40 and compare your OT pay to what the calculation above says you were owed.
Screenshot
Electronic Time Entries
If your employer uses a digital timekeeping system, your entries can be altered after the fact — itself a documented violation if it results in underpayment. Screenshot your entries at the end of each week before logging out.
Do this
Raise It in Writing with HR First
Their written response — or non-response — becomes part of your documentation. A paper trail showing you raised the issue and were ignored strengthens a willful violation claim and extends the lookback period to three years.
Frequently Asked Questions
Does overtime apply to part-time employees?
Yes. If a part-time non-exempt employee works more than 40 hours in a workweek, they're entitled to overtime for those excess hours. Part-time status doesn't create an exemption — hours worked in that workweek do.
Can my employer average my hours across two weeks to avoid paying overtime?
No. Overtime is calculated on a single workweek basis under federal law. An employer cannot average 35 hours one week and 45 the next and claim no overtime is owed. Each workweek stands alone. Some states are even stricter on this point.
My offer letter says I'm salaried and not eligible for overtime. Is that enforceable?
Only if you genuinely meet all three criteria for an applicable exemption. An offer letter cannot override the FLSA. If you're misclassified, the letter is legally irrelevant — your employer still owes you overtime going back up to three years.
What if I worked overtime but my employer says it wasn't "authorized"?
The FLSA requires employers to pay for all hours they "suffered or permitted" an employee to work — including unauthorized overtime. The employer's remedy is discipline, not non-payment. Refusing to pay for hours worked is a wage violation regardless of any authorization policy.
How far back can I file an overtime claim?
Two years under the FLSA for standard violations, three years for willful violations. Many states allow longer periods — California and New York allow up to four years for wage claims. Filing a complaint with the Department of Labor or a private lawsuit starts the process.
