How many work hours are in a year?

Almost every hourly-to-salary conversion you will see rests on one number: 2,080 hours. It is worth knowing where it comes from, because it is a convention rather than a measurement, and the gap between the two is where people get surprised.

Where 2,080 comes from

Forty hours a week, multiplied by fifty-two weeks:

40 × 52 = 2,080

That is the whole derivation. It assumes a full-time schedule, every week of the year worked, and no adjustment for holidays or leave.

Why it is not exactly right

A calendar year is 365 days, which is 52 weeks and one day — 52 weeks and two days in a leap year. So the count of actual weekdays in a year is 260 or 261, depending on which day the year starts on and whether it is a leap year.

At eight hours a day that is 2,080 or 2,088 hours. The convention rounds to the lower figure and ignores the drift, which is fine for comparing offers and slightly wrong for exact payroll.

More importantly, 2,080 counts paid hours, not worked hours. Two things pull those apart:

• Paid holidays and paid leave are paid but not worked. Ten paid holidays means the same salary buys 2,000 worked hours rather than 2,080 — so your real hourly rate is higher than the naive division suggests.
• Unpaid leave is neither paid nor worked. Two unpaid weeks takes 2,080 down to 2,000 paid hours, and the annual total down with it.

Those two move in opposite directions, and most salary calculators ignore both. The controls on every calculator page here let you set them.

Other schedules

Not every full-time job is forty hours. Common alternatives:

| Hours a week | Hours a year | | --- | --- | | 40 | 2,080 | | 37.5 | 1,950 | | 35 | 1,820 | | 30 | 1,560 | | 20 | 1,040 |

A 37.5-hour week — standard in a lot of office and public-sector work, usually from an unpaid half-hour lunch — is 130 hours a year less than a 40-hour week. On a $30 rate that is $3,900. It is the sort of difference that decides between two offers and never appears in either of them.

When the number stops being useful

For a contractor, 2,080 is close to meaningless. Nobody bills every working hour: selling, proposals, admin and the gaps between contracts are all real hours that no client pays for. A bill rate multiplied by 2,080 is the top line of a business, not a salary, and it has self-employment tax, unpaid leave and unbilled time still to come out of it.

For salaried exempt work, the number is only as good as the hours actually worked. A $120,000 salary is $57.69 an hour at 2,080 hours and $46.15 at 2,600 — a fifty-hour week. The salary does not change. The rate does.

The short version

Use 2,080 to compare like with like. Stop using it the moment paid leave, unpaid leave, a non-standard week, or self-employment enters the picture, and put the real numbers in instead.
