Example 1
- email 80
- tabs 20
- files 40
- pace 15 min / 10
- tidy-up 30
3 hours short
80 + 20 + 40 = 140. 15 ÷ 10 = 1.5. 140 × 1.5 = 210. 30 − 210 = −180 minutes, which is 3 hours.
The calculator uses the numbers you enter: unread emails, open tabs, unsorted files, and minutes to tidy 10 things. 140 things at 1.5 minutes need 210 minutes. 30 minutes is 3 hours short. Phone notifications sit in the grid.
The calculator does not open the inbox and does not clean files. Phone notifications are optional and do not change the main result. Screen time: non-work screen time.
Enter data and click Calculate.
The calculator adds emails, tabs, and files, multiplies the sum by minutes per thing from the pace for 10 things, then subtracts that time from tidy-up minutes. 80 plus 20 plus 40 is 140. 15 ÷ 10 = 1.5. 140 × 1.5 = 210. 30 − 210 = −180 minutes, which is 3 hours short.
The main result comes from emails, tabs, files, pace, and tidy-up minutes. Phone notifications are optional and do not change the main result.
Second example: 40 things at 1 minute and 60 minutes is 0.3 hours spare. Third: 320 things at 2 minutes and 20 minutes is 10.3 hours short.
The calculator does not open the inbox and does not clean files. A comma in 12.5 is read the same way as a period.
Result in hours = (tidy-up minutes − things × minutes for 10 ÷ 10) ÷ 60. At 80, 20, 40, 15 and 30: (30 − 210) ÷ 60 = −3. Notifications are optional.
140 things at 1.5 minutes and 30 minutes is 3 hours short.
3 hours short
80 + 20 + 40 = 140. 15 ÷ 10 = 1.5. 140 × 1.5 = 210. 30 − 210 = −180 minutes, which is 3 hours.
0.3 hours spare
20 + 8 + 12 = 40. 10 ÷ 10 = 1. 40 × 1 = 40. 60 − 40 = 20 minutes, which is 0.3 hours.
10.3 hours short
200 + 40 + 80 = 320. 20 ÷ 10 = 2. 320 × 2 = 640. 20 − 640 = −620 minutes, which is 10.3 hours.
80 + 20 + 40 = 140. 15 ÷ 10 = 1.5. 140 × 1.5 = 210. 30 − 210 = −180 minutes, which is 3 hours.
Result in hours = (tidy-up minutes − things × minutes for 10 ÷ 10) ÷ 60. At 80, 20, 40, 15 and 30: (30 − 210) ÷ 60 = −3.
40 things at 1 minute and 60 minutes is 0.3 hours spare.
320 things at 2 minutes and 20 minutes is 10.3 hours short.
The calculator does not open the inbox and does not clean files. Phone notifications are optional.
No. The main result comes from emails, tabs, files, pace, and tidy-up minutes. Phone notifications are optional.
The backlog is emails, tabs, and files times minutes per thing. Pace is minutes for 10 things. Tidy-up is the minutes you give in a week.
Yes. 12.5 and 12,5 are read the same way.
The result comes from the numbers you enter. This is spare time or a shortfall, not an inbox clean-up.
