Example 1
- Writing 6 h
- Sheets 4 h
- Customers 2 h
- Meetings 8 h
- Physical work 12 h
- Decisions 8 h
- Rise 5
12 / 40 = 30%. From 2026, the share reaches half the week in 2030.
AI task exposure calculator
The result is the percentage of the week's hours spent on writing, spreadsheets, and customer messages. Without the meetings box, the calculator divides those hours by the whole week you enter. 6 hours of writing, 4 hours of spreadsheets, and 2 hours of customer messages in a 40-hour week come to 30%. If you enter a rise of 5 percentage points a year and the calendar on this device shows 2026, a straight line from that rise reaches half the week in 2030. That line is not a forecast of the labor market, and 2030 is not a layoff date.

How the results are calculated
Writing, sheets, customers12 h
Week40 h
Share30%
With the meetings box unchecked, the calculator divides hours of writing and code, spreadsheets, and customer messages by every hour you enter. 6 + 4 + 2 = 12. Meetings take 8 hours, physical work 12, and decisions 8, so the week is 40 hours. 12 / 40 = 30%.
An empty hours field counts as zero. If all of the hour fields are empty, the calculator does not calculate. The calculator does not accept a negative number, or a number above 168 in one field, or a sum above 168 hours in the week.
A year appears only when you enter a rise. The calculator reads the year from the calendar on this device and adds the years needed for the share to reach 50%. At 30% and a rise of 5 points from 2026, that year is 2030. That year is a straight line from the rise you type. It is not a forecast of the labor market. When the share is already at least 50%, there is no future year. The currency and unit switches at the top of the page do not convert these hours. The meetings box starts unchecked. When it is checked, meetings count in the share, so 6 + 4 + 2 + 8 in a 40-hour week is 50%.
How to use
- Enter the hours in the same order as the fields, for example 6, 4, 2, 8, 12, and 8.
- Leave the rise empty if you only want the percentage, with no year.
- Click Calculate. With the meetings box unchecked, 12 of 40 hours is 30%.
- Enter 5 in the rise field when the share is below 50% and you want the year it reaches half the week.
- Check the meetings box only when meetings should count in the share.

Hours in the week
With the box unchecked, the percentage uses writing, spreadsheets, and customer messages. When the box is checked, meetings count in that share as well. Physical work and decisions are part of the full week, but not of the percentage.
- share
- These are the hours spent on writing, spreadsheets, and customer messages, plus meetings when the box is checked. The calculator divides them by the whole week you enter. With the box unchecked, 12 / 40 = 30%.
- rise
- The number of percentage points added to the share each year. At 5 points from 30%, half the week is 4 years away.
Examples
Example 2
- Writing 15 h
- Sheets 8 h
- Customers 5 h
- Meetings 6 h
- Physical work 2 h
- Decisions 4 h
- Rise 5
28 / 40 = 70%. The share is already above half, so there is no future year.
Example 3
- Writing 6 h
- Sheets 4 h
- Customers 2 h
- The other hours match example 1
- Rise left empty
The same week comes to 30%, and the result has no year. The rise field stays empty. The calculator does not insert 5 from the example.
Example 4
- Hours from example 1
- Meetings box checked
- Rise 5
20 / 40 = 50%. The share is already half the week, so there is no future year.
Common questions
Where does 30% come from?
It comes from the hours you enter. 6 + 4 + 2 = 12, and the example week is 40 hours. 12 / 40 = 30%.
Is 2030 a layoff date?
No. From the example's 30%, with a rise of 5 points a year and 2026 on this device's calendar, the share reaches 50% in 2030. That year is a straight line from the rise you type. It is not a forecast of the labor market.
What if the rise field is empty?
The calculator shows the percentage, with no future year. The field stays empty. The calculator does not insert 5 from the example.
Does an empty hours field count as zero?
Yes. An empty field is zero hours. If all of the hour fields are empty, the calculator asks for hours and does not calculate.
Does the calculator know my job title?
No. There is no list of occupations. Only the hours in the fields count.
Do the switches at the top convert the hours?
No. The currency and unit switches do not convert the numbers you typed.
What does the meetings box do?
When it is checked, meetings count in the share. 6 + 4 + 2 + 8 = 20, and the week is 40 hours, so the share is 50%. With the box unchecked, the share stays 30%.
