Salary Calculator
Calculate your annual salary and take-home pay
Convert between hourly, weekly, monthly, and annual salary. Our calculator also estimates your take-home pay after federal and state taxes.
🔬Salary Conversion Methodology
Based on standard full-time work: 40 hours/week, 52 weeks/year = 2,080 hours/year. This is the most common calculation method.
Formula
Hourly = Annual / 2080
Annual = Hourly × 2080
Monthly = Annual / 12
Bi-weekly = Annual / 26
Weekly = Annual / 52Where:
2080= Standard work hours per year52= Weeks per year26= Bi-weekly pay periodsLimitations:
- Assumes no paid time off
- Doesn't account for overtime
- Part-time schedules vary
📜 Historical Background
The 40-hour work week became standard in the United States through decades of labor struggle and legislative action. In the 19th century, 10-14 hour days, 6-7 days per week were common in industrial settings. Labor activists championed the 'Eight-Hour Day' movement, with the slogan 'Eight hours for work, eight hours for rest, eight hours for what you will.' Ford Motor Company voluntarily adopted the 40-hour week in 1926, finding that productivity actually increased. The Fair Labor Standards Act of 1938 codified the 40-hour week nationally, establishing overtime pay requirements beyond 40 hours. The resulting 2,080 hours per year (40 × 52) became the standard denominator for salary-to-hourly conversions. This number appears throughout HR systems, government statistics, and compensation analyses. While many workers today work more or fewer than 40 hours, and some countries have adopted shorter standard weeks (France's 35 hours, for example), the 2,080-hour assumption remains the global benchmark for full-time equivalent calculations.
🔬 Scientific Basis
The standard conversion assumes 40 hours per week for 52 weeks, yielding 2,080 annual hours. However, this doesn't reflect actual hours worked for most employees. Average Americans take 10-15 paid holidays and 10-20 vacation days, reducing actual work to approximately 1,900-1,950 hours annually. Exempt salaried employees often work more than 40 hours without additional compensation—surveys suggest many work 45-50+ hours weekly. The Bureau of Labor Statistics tracks actual hours worked: in 2024, full-time workers averaged 42.4 hours per week. For accurate comparison between salaried and hourly positions, consider: effective hourly rate = annual salary / actual hours worked. A $75,000 salary with 50 hours/week equals $28.85/hour effective rate; at 40 hours it's $36.06/hour. This 20% difference significantly affects job comparison, especially when evaluating positions that require extensive overtime.
💡 Practical Examples
- $75,000 annual salary: Hourly = $75,000 / 2,080 = $36.06/hour. Monthly = $6,250. Bi-weekly = $2,885. Weekly = $1,442.
- $25/hour full-time: Annual = $25 × 2,080 = $52,000. This helps compare hourly jobs to salaried positions.
- Part-time comparison: 30 hours/week at $20/hour = $20 × 30 × 52 = $31,200 annual. Compare to full-time offer at $35,000 for effective rate.
⚖️ Comparison with Other Methods
The standard 2,080-hour assumption works well for comparing like-to-like: two full-time salaried positions with similar hour expectations. It becomes problematic when comparing salaried positions with different hour norms (tech startup vs government job) or when comparing salary to hourly with overtime potential. For accurate comparison, calculate effective hourly rate using realistic hour estimates. Some employers use 2,000 hours (40 hours × 50 weeks, assuming 2 weeks unpaid time off) or 1,920 hours (treating 8 holidays as non-work). The 26 bi-weekly periods create an interesting quirk: in some years, there are 27 pay periods, giving employees an 'extra' paycheck (though annual salary doesn't change). For budgeting, understanding your specific pay frequency matters more than theoretical annual amounts.
⚡ Pros & Cons

Frequently Asked Questions
How do I convert hourly to annual salary?
Multiply hourly rate × hours per week × 52 weeks. $20/hr × 40 × 52 = $41,600/year.
What is take-home pay?
Gross salary minus all deductions: federal tax, state tax, Social Security, Medicare, benefits.
How much of my salary goes to taxes?
Typically 20-35% depending on income and location. Our calculator estimates this.
How do I calculate my effective tax rate?
Total taxes paid ÷ gross income × 100. This is usually lower than your marginal bracket.
Should I negotiate salary or hourly?
Salary provides stability, hourly may pay more with overtime. Consider your work patterns.
