Understanding Salary vs. Hourly Pay
A salary is a fixed annual amount paid regardless of exact hours worked each week. An hourly wage is paid for each hour worked, with overtime (typically 1.5×) for hours over 40 per week. Converting between them requires knowing your hours per week and weeks per year. The standard is 40 hours × 52 weeks = 2,080 annual hours.
Pay Period Comparison
The same annual salary produces different amounts per paycheck depending on how frequently you are paid:
- Weekly (52 periods): Annual ÷ 52
- Biweekly (26 periods): Annual ÷ 26
- Semi-monthly (24 periods): Annual ÷ 24
- Monthly (12 periods): Annual ÷ 12
Biweekly is the most common in the US. Note that biweekly (every two weeks) is not the same as semi-monthly (twice a month). Biweekly produces two months per year with three paychecks.
Why Gross Pay and Take-Home Pay Differ
Gross pay is agreed compensation before deductions. Take-home (net) pay is what you receive after federal income tax, state income tax, FICA taxes (Social Security 6.2% + Medicare 1.45%), and benefit contributions. The combined effective rate is typically 18–35% for most US workers. Use the Take-Home Pay Calculator to model your specific situation.
Overtime
Under the federal Fair Labor Standards Act, non-exempt hourly employees earn at least 1.5× their regular rate for hours worked over 40 in a workweek. Some states impose stricter rules (California requires daily overtime after 8 hours). Salaried employees classified as exempt are generally not entitled to overtime. See the Overtime Pay Calculator for estimates.
