Work Facts

Work is one of the largest single consumers of human time. According to the Bureau of Labor Statistics American Time Use Survey, the average employed American works about 7.7 hours per day on days they work — equating to roughly 1,800 hours per year.

The 90,000-hour figure

The widely cited "90,000 hours at work" figure assumes 40 hours per week, 50 weeks per year, over a 45-year career from age 22 to 67. That equals exactly 90,000 hours — roughly 10.3 full years of continuous 24-hour days, or about 13% of an 80-year life.

Work and well-being

Research consistently shows that the relationship between work hours and well-being is non-linear. A study in Nature Human Behaviour found that working around 25 hours per week is associated with peak cognitive performance for adults over 40 — more than that actually reduces performance. The OECD's Better Life Index consistently ranks work-life balance as one of the most important factors in overall life satisfaction.

💡 If you work 40 hours per week from 22 to 67, you'll spend more time at work than you will on weekends during that same period — because weekends only account for 2/7 of each week.

Average Working Hours by Country

How much people work varies dramatically by country. Here's data from the OECD annual hours worked statistics.
