Example 1
- plan 6 h
- time 4 h
- interruptions 8
- interrupt 10 min
- empty days 6
3.3 hours below
4 − (8 × 10 ÷ 60) − 6 = −3.3, so 3.3 hours below. Empty days sit in the grid.
The calculator uses the numbers you enter: creative hours, interruptions, and the plan. 4 minus 8 times 10 over 60 minus 6 is 3.3 hours below. Empty days sit in the grid.
The calculator does not score idea quality and does not lock the calendar. Focus: focus time after interruptions.
Enter data and click Calculate.
The calculator subtracts interruptions times minutes over 60 from creative hours, then subtracts the plan. 4 minus 1.3 minus 6 is 3.3 hours below.
The main result comes from hours, interruptions, and the plan. Days without a creative block sit in the grid.
Second example: 5 minus 0 minus 5 is 0. Third: 3 minus 3 minus 8 is 8 hours below.
The calculator does not score idea quality and does not lock the calendar. A comma in 12.5 is read the same way as a period.
Result = hours − (interruptions × minutes ÷ 60) − plan. At 4, 8, 10 and 6: 4 − 1.3 − 6 = −3.3, so 3.3 hours below.
4 minus 8 times 10 over 60 minus 6 is 3.3 hours below.
3.3 hours below
4 − (8 × 10 ÷ 60) − 6 = −3.3, so 3.3 hours below. Empty days sit in the grid.
0 hours versus the plan
5 − 0 − 5 = 0.
8 hours below
3 − (12 × 15 ÷ 60) − 8 = −8, so 8 hours below.
4 − (8 × 10 ÷ 60) − 6 = −3.3, so 3.3 hours below. Empty days sit in the grid.
Result = hours − (interruptions × minutes ÷ 60) − plan. At 4 hours, 8 interruptions of 10 minutes and a plan of 6 the result is 3.3 hours below.
5 − 0 − 5 = 0.
3 − (12 × 15 ÷ 60) − 8 = −8, so 8 hours below.
The calculator does not score idea quality and does not lock the calendar. The hourly rate is optional.
No. The main result comes from hours, interruptions, and the plan. Empty days and the rate sit in the grid.
Hours are creative time you keep. Interruptions are cuts into that time. The plan is the threshold you set.
Yes. 12.5 and 12,5 are read the same way.
The result comes from the numbers you enter. This is hours after interruptions versus the plan, not a creative-protection score.
