Work Hours Per Year
Quick answer: A standard full-time year is 2,080 hours (40 hours × 52 weeks). Your true number is lower once time off is subtracted: for example, 40 hours a week with 3 vacation weeks and 10 paid holidays gives 40 × 49 − 10 × 8 = 1,880 work hours per year.

Your salary is really an hourly rate in disguise — but only if you know how many hours you actually work. This work hours per year calculator turns your weekly schedule, vacation weeks, paid holidays, and unpaid days off into your true annual work hours.

Estimate only. Assumes a 5-day week, so each day off counts as weekly hours ÷ 5, and hours spread evenly across the year.
How to use this calculator
Enter the hours you actually work each week (excluding unpaid lunch breaks), then your vacation weeks, paid holidays, and unpaid days off for the year. The result updates instantly as you type.
Worked example: 40 hours/week, 3 vacation weeks, 10 paid holidays, 0 unpaid days. Daily rate = 40 ÷ 5 = 8 hours. Annual = 40 × 52 − 3 × 40 − 10 × 8 = 2,080 − 120 − 80 = 1,880 hours per year — 90.4% of the 2,080-hour standard year.
How it works
Annual work hours = (hours/week × 52) − (vacation weeks × hours/week) − ((paid holidays + unpaid days) × hours/week ÷ 5). Whole days off are valued at one-fifth of the weekly hours, which assumes a 5-day work week. If you work compressed shifts (for example four 10-hour days), each day off is really worth more than hours ÷ 5, so the result will read slightly high.

Method & sources
The method is exact arithmetic on your inputs: gross scheduled hours minus time-off hours, with each day off valued at weekly hours ÷ 5. It is an estimate because it assumes hours are spread evenly and all time off falls on would-be workdays. Figures are rounded to one decimal.

Frequently asked questions
How many work hours are in a year?
A standard full-time schedule is 2,080 hours per year (40 hours × 52 weeks). Your actual number is lower once vacation, holidays, and unpaid time off are subtracted — for example, 40 hours a week with 3 vacation weeks and 10 holidays works out to 1,880 hours.
Do lunch breaks count as work hours?
Only if you are paid for them. Enter the hours you actually work: if your day runs 8:30 to 5:00 with an unpaid 30-minute lunch, that is 8 hours a day, or 40 hours a week — not 42.5.
Can part-time workers use this calculator?
Yes — enter your actual weekly hours. For example, 24 hours a week with 1 vacation week and 5 holidays gives 24 × 52 − 24 − 5 × 4.8 = 1,200 hours per year.
Why is each day off worth weekly hours ÷ 5?
This calculator counts each paid holiday or unpaid day as one full day — a fifth of a 5-day work week. If you work four 10-hour shifts, a day off is really worth 10 hours, so treat the result as a slight overestimate.
What is the difference between this and 2,080 hours?
2,080 is the gross figure for a full-time schedule before any time off. This calculator subtracts your vacation weeks, paid holidays, and unpaid days to show the hours you actually work.
