Where 2,080 comes from
The math is simple:
- 40 hours per week x 52 weeks = 2,080 hours
This assumes a five-day, eight-hour workday with no time off. The 2,080 figure has been the standard payroll benchmark for decades and is the number most private-sector employers use when converting between annual salary and hourly rate.
The US Office of Personnel Management (OPM) uses 2,087 hours for federal pay calculations, because it averages the actual number of workdays across a 28-year calendar cycle that includes leap years. Private employers almost universally round to 2,080, since the seven-hour difference has a negligible effect on an individual paycheck, about 0.3%. Another route to the same number is counting workdays: a year holds about 260 weekdays (52 weeks x 5), and 260 x 8 hours also equals 2,080 before any holidays come out. Employers often use 2,080 as the basis for accruing paid time off and for prorating a partial year, so the figure shapes more than just your hourly rate.
Adjusted hours after holidays and PTO
No full-time worker actually logs 2,080 hours unless they take zero days off. Here is how common time-off patterns change the total. There are 11 federal holidays, and each eight-hour day away subtracts 8 from the baseline:
| Scenario | Days off | Hours off | Actual work hours |
|---|---|---|---|
| Baseline (no time off) | 0 | 0 | 2,080 |
| Federal holidays only | 11 | 88 | 1,992 |
| Holidays + 10 vacation days | 21 | 168 | 1,912 |
| Holidays + 15 vacation + 5 sick | 31 | 248 | 1,832 |
To find your own number, use this formula: 2,080 minus (total paid days off x 8). Count every holiday, vacation day, and typical sick day you actually take.
Worked example: suppose you use all 11 federal holidays, 12 vacation days, and 4 sick days. That is 27 days, or 216 hours, away from work. Your actual hours are 2,080 minus 216, which equals 1,864 for the year. Dividing a $65,000 salary by 1,864 gives a real rate of about $34.87 per hour, well above the $31.25 the flat 2,080 figure implies. The more paid time off you take, the wider that gap grows.
Part-time and non-standard schedules
If you work fewer than 40 hours per week, multiply your weekly hours by 52:
- 30 hours/week: 30 x 52 = 1,560 hours/year
- 20 hours/week: 20 x 52 = 1,040 hours/year
- Four-day week (32 hours): 32 x 52 = 1,664 hours/year
Some industries use different baselines. Healthcare workers on 36-hour weeks log about 1,872 hours; firefighters on 24/48 rotations can exceed 2,900. Compressed schedules such as four 10-hour days, or a 9/80 arrangement, still total 2,080 annual hours but spread them across fewer workdays, which changes PTO accounting and overtime eligibility under some state laws.
A few more common totals: 25 hours a week is 1,300 hours a year, and 35 hours a week is 1,820 hours. Multiply any weekly figure by 52 for the annual total, then subtract paid days off the same way full-time workers do. Job-share arrangements split one 2,080-hour role between two people, so each books roughly 1,040 hours, and shift workers on rotating schedules should average their weekly hours across a full rotation before multiplying by 52.
Using 2,080 to convert salary to hourly
Divide your annual salary by 2,080 to get your equivalent hourly rate:
- $50,000 / 2,080 = $24.04/hour
- $75,000 / 2,080 = $36.06/hour
- $100,000 / 2,080 = $48.08/hour
Going the other direction, multiply your hourly rate by 2,080 to get the annual figure. This is the same formula the salary-to-hourly calculator and the annual salary calculator use. It is a fast estimate, not an exact contract figure, because it ignores paid time off.
One caution when weighing a salaried offer against contract or self-employed work: as an employee you pay 7.65% in FICA and your employer pays the other half, but a self-employed person owes the full 15.3% self-employment tax on net earnings. A contract hourly rate therefore has to sit well above the salaried equivalent, often 20% or more, just to leave the same amount in hand after taxes and lost benefits.
Common mistakes and edge cases
The 2,080 shortcut is fine for quick math, but a few mistakes distort real numbers:
- Ignoring PTO when pricing your time. An employee earning $60,000 who works 1,912 hours after holidays and two weeks of vacation effectively earns $31.38 per hour, not the $28.85 that the flat 2,080 formula suggests.
- Treating 2,080 as a legal definition. It is a payroll convention, not a full-time mandate.
- Assuming semi-monthly periods hold exactly 86.67 hours. Some periods span more workdays than others.
Edge cases to keep in mind:
- Hourly vs. salaried on semi-monthly pay: hourly workers see fluctuating pay because workdays per period vary; salaried workers receive the same amount each period.
- Leap years and federal work: the OPM 2,087 figure exists precisely to smooth out leap-year variation across decades.
- Comparing offers: a job with 20 PTO days cuts real hours to about 1,920, raising your true hourly rate by roughly 8% versus the 2,080 baseline. Factor benefits and PTO into any offer comparison, not just the headline salary.
Work hours by pay-period type
The number of hours behind each paycheck depends on your pay frequency:
| Pay frequency | Pay periods/year | Hours per period (40 hr/wk) |
|---|---|---|
| Weekly | 52 | 40 |
| Biweekly | 26 | 80 |
| Semi-monthly | 24 | 86.67 |
| Monthly | 12 | 173.33 |
The biweekly figure of 80 hours is the most common in US payroll. Because months differ in length, the hours behind a monthly or semi-monthly paycheck are not identical from period to period; salaried employees are paid the same amount regardless, while hourly employees on these schedules see pay rise and fall with the number of workdays.

Frequently asked questions
Is 2,080 hours the legal definition of full-time?
There is no single federal legal definition of full-time hours. The FLSA does not define full-time. The ACA treats 30 hours per week as full-time for benefits eligibility. The 2,080 figure is a payroll convention, not a legal mandate.
Do salaried employees work more than 2,080 hours?
Many do. Exempt salaried employees are not entitled to overtime pay under the FLSA, so hours above 40 per week are not separately compensated. A salaried worker who averages 45 hours per week logs about 2,340 hours per year.
How many work hours are in a month?
The standard estimate is 173.33 hours per month (2,080 divided by 12). The actual number varies by month because months have different numbers of weekdays; February can have as few as 20 workdays (160 hours) while some months have 23 (184 hours).
Why does the federal government use 2,087 instead of 2,080?
OPM uses 2,087 because it averages the actual weekdays across a 28-year calendar cycle that includes leap years. The seven-hour difference has a negligible effect on individual paychecks but matters at scale for federal budgeting.
How do I calculate my real hourly rate including PTO?
Subtract your total paid days off (holidays, vacation, sick) times 8 from 2,080, then divide your annual salary by that adjusted number. The fewer hours you actually work, the higher your true hourly rate.
