A knowledge worker in Chicago enters 8 hours sleep, 9 hours work (including lunch), 1 hour commute, 2 hours screen time, and 0.5 hours exercise. Over an 80-year life, that adds up to 26.7 years sleeping, 30 years working, 3.3 years commuting, 6.7 years on screens, and 1.7 years exercising. The numbers make them reconsider their commute.
A freelancer in Berlin tracks their time for a week and discovers they spend 3.5 hours per day on social media and email. The calculator shows that is 11.7 years of their remaining life if they keep it up. They set a screen time limit the same day.
A new parent in Tokyo enters 6 hours sleep, 10 hours work, 1.5 hours commute, and 3 hours family time. The lifetime view shows 20 years working and only 6 years with family over the next 40 years. They decide to negotiate remote work to recover 2.5 years of commute time.
A retiree in Miami enters 7 hours sleep, 4 hours screen time, 2 hours exercise, and 3 hours social time. They see that 13.3 years of their remaining 20 will go to screens and only 6.7 years to social connection. They join a walking group the next week.
You enter how many hours per day you spend on each of 10 categories: sleep, work, commute, exercise, meals, family, screen time, personal care, social, and other. The calculator sums these to check if they total 24 hours.
For each category, the calculator multiplies daily hours by 365 to get annual hours, then by your life expectancy (default 80 years) to get lifetime hours. It converts lifetime hours to years by dividing by 8,760 (365 times 24).
The donut chart shows your daily breakdown as proportions of a 24-hour day. Each category gets a colored slice sized by its hours. The lifetime breakdown table shows the same data projected over your full life expectancy.
Benchmark indicators next to sleep and exercise show whether your allocation meets WHO guidelines. A green check means you are within the recommended range. A red X means you are outside it.

Things to keep in mind
How does the time budget calculator work?
You enter how many hours per day you spend on each category. The calculator multiplies by 365 to get yearly hours, then by your life expectancy to get lifetime hours. It converts those to years so you can see how much of your life goes to each activity.
What if my daily hours don't add up to 24?
The calculator shows a warning if your total is over or under 24 hours. You can adjust the sliders until the total equals 24, or leave it as is if your schedule varies day to day.
How are lifetime hours calculated?
Daily hours are multiplied by 365 to get annual hours, then by your life expectancy (default 80 years). For example, 8 hours of sleep per day over 80 years is 233,600 hours, which is 26.7 years of sleeping.
What are the benchmark recommendations based on?
Sleep benchmarks use WHO guidelines of 7 to 9 hours for adults. Exercise uses the WHO recommendation of 150 minutes per week, which is about 0.36 hours per day. Work uses the standard 8-hour workday.
Should I include weekends in my daily average?
Yes. Enter your average daily hours across the whole week. If you sleep 6 hours on weekdays and 10 hours on weekends, your average is about 7.1 hours per day. This gives the most accurate lifetime projection.
Can I use this for time management?
Yes. Seeing that you spend 10 years of your life on screens or 3 years commuting can motivate changes. Many users adjust their commute, reduce screen time, or increase exercise after seeing the lifetime numbers.
The lifetime projections assume your current daily routine stays constant for your entire life, which is unlikely. People change jobs, retire, and adjust habits. Use the numbers for perspective on your current allocation, not as a prediction of how you will spend every future year.
