Work Hours Calculator: Track Your Weekly Hours

Q: How is overtime pay calculated in the US?

Under the Fair Labor Standards Act (FLSA), non-exempt employees earn 1.5× their regular hourly rate for hours worked beyond 40 in a workweek. Some states require higher rates: California pays 2× for hours over 12/day and 1.5× for hours over 8/day.

Q: How do I convert annual salary to hourly rate?

Divide annual salary by total working hours per year. For a standard schedule: Annual Salary ÷ 2,080 = Hourly Rate. 2,080 = 52 weeks × 40 hours. For example, $50,000/year ÷ 2,080 = $24.04/hour.

Q: Does my lunch break count as work time?

In the US, bona fide meal breaks (typically 30+ minutes) where you're completely relieved of duties do NOT count as work time. Short breaks (5-20 minutes) DO count as work time. State laws vary — California requires a 30-minute meal break for shifts over 5 hours.

Q: What's the difference between exempt and non-exempt employees?

Non-exempt employees are entitled to minimum wage and overtime pay (1.5× after 40 hours/week). Exempt employees are not entitled to overtime, regardless of hours worked. Exemption depends on salary level ($684+/week) and job duties (executive, administrative, professional, computer, or outside sales).

Tracking your work hours accurately isn't just about getting paid correctly — it's a legal right, a financial necessity, and a key to maintaining work-life balance. Whether you're an hourly employee, a freelancer, or a salaried worker trying to understand your true hourly rate, this guide covers everything you need to know about work hour tracking, overtime calculation, and labor law requirements.

Why Tracking Work Hours Matters

Work hour tracking serves multiple critical purposes:

Accurate pay: Ensure you're paid for every hour you work, including overtime
Legal compliance: Meet FLSA and state labor law record-keeping requirements
Project billing: Freelancers and contractors need accurate records for client invoices
Productivity analysis: Understand where your time goes and identify inefficiencies
Work-life balance: Recognize when you're overworking and set boundaries
Tax documentation: Provide evidence for deductions and business expense claims

Understanding Overtime: A Complete Breakdown

US Federal Overtime Law (FLSA)

The Fair Labor Standards Act (FLSA) establishes the baseline for overtime in the United States:

Standard threshold: 40 hours per workweek
Overtime rate: 1.5× regular hourly rate ("time and a half")
Applies to: Non-exempt employees only
Workweek definition: A fixed, recurring period of 168 hours (7 consecutive 24-hour periods). It doesn't have to be Sunday–Saturday.

Example: Weekly Pay with Overtime

Employee earns $20/hour and works 48 hours in a week:

Regular pay: 40 hours × $20 = $800
Overtime pay: 8 hours × $30 (1.5×) = $240
Total weekly pay: $1,040

State Overtime Laws (Stricter Than Federal)

Several states have overtime rules that exceed federal requirements:

State	Daily Overtime	Weekly Overtime	Special Rules
California	1.5× after 8 hrs/day; 2× after 12 hrs/day	1.5× after 40 hrs; 2× after 8 hrs on 7th day	First 8 hrs on 7th day = 1.5×
Alaska	1.5× after 8 hrs/day	1.5× after 40 hrs	Daily OT applies
Colorado	1.5× after 12 hrs/day	1.5× after 40 hrs	Also after 12 consecutive hrs
Nevada	1.5× after 8 hrs/day (if <$15/hr)	1.5× after 40 hrs	Daily OT for lower-wage workers
Washington	None	1.5× after 40 hrs	Additional OT for certain industries

⚠️ Important: When federal and state laws differ, the employee is entitled to whichever provides greater benefit. Always check your state's specific labor laws.

Exempt vs. Non-Exempt Employees

Not all employees are entitled to overtime. Understanding the distinction is crucial:

Non-Exempt Employees

Entitled to minimum wage and overtime (1.5× after 40 hrs/week)
Typically paid hourly, but can be salaried
Must be paid for all hours worked

Exempt Employees

Not entitled to overtime, regardless of hours worked
Must meet salary threshold ($684/week or $35,568/year as of 2025)
Must perform exempt job duties (executive, administrative, professional, computer, outside sales)

Salary to Hourly Rate Conversion

Knowing your true hourly rate is essential for comparing job offers, negotiating pay, and understanding your time's value. Here's how to convert:

Standard Method (52 Weeks × 40 Hours)

Hourly Rate = Annual Salary ÷ 2,080

Where 2,080 = 52 weeks × 40 hours/week.

Conversion Examples

Annual Salary	Hourly Rate	Daily Rate (8h)	Weekly Rate
$30,000	$14.42	$115.38	$576.92
$50,000	$24.04	$192.31	$961.54
$75,000	$36.06	$288.46	$1,442.31
$100,000	$48.08	$384.62	$1,923.08
$150,000	$72.12	$576.92	$2,884.62

Adjusted Method (Accounting for Actual Work Days)

If you want a more realistic rate accounting for holidays and vacation:

10 holidays + 10 vacation days = 20 days off
260 work days − 20 = 240 actual work days
240 days × 8 hours = 1,920 hours
Adjusted Hourly Rate = Annual Salary ÷ 1,920

For $75,000: $75,000 ÷ 1,920 = $39.06/hour (vs. $36.06 standard — 8% higher).

Hourly to Salary Conversion

Reverse the calculation to estimate annual salary from an hourly rate:

Annual Salary = Hourly Rate × 2,080

Hourly Rate to Salary Examples

Hourly Rate	Annual Salary	Monthly (Gross)
$15	$31,200	$2,600
$25	$52,000	$4,333
$35	$72,800	$6,067
$50	$104,000	$8,667
$75	$156,000	$13,000

What Counts as "Work Time"?

The FLSA has specific rules about what activities count as compensable work time:

Counted as Work Time

All time spent performing principal work activities
Travel between job sites during the workday
Training required by the employer
On-call time where you're restricted from personal activities
Time spent at the workplace before/after your shift if performing work duties
Short breaks (5-20 minutes) — these are compensable
Checking work email or taking calls outside scheduled hours

NOT Counted as Work Time

Commuting to/from the primary workplace
Bona fide meal breaks (30+ minutes, completely relieved of duties)
Personal activities during travel (reading, sleeping on a flight)
On-call time at home where you're free to use your time as you wish
Voluntary attendance at training not related to your job

⚖️ Legal Note: Checking work email after hours, even briefly, may count as work time. If it pushes you over 40 hours, you may be entitled to overtime. Track these micro-moments.
