Cost per hour saved on personal tasks

The calculator uses the numbers you enter: tools cost, hours saved, and fixes. 25 over 2.5 is 10 per net hour. The task share sits in the grid.

The calculator does not turn automation on and does not connect to an account. Fees: annual cost of late fees.

Input data

Enter tasks, hours saved, tools cost, and fixes. You can leave the hourly rate and the people count blank.

Optional context

These two fields are optional. The hourly rate compares the cost of a freed hour with the value of your time. The people count shows tools cost per person. A blank field skips that context and does not change the main result.

How it works

The calculator subtracts fix minutes over 60 from hours saved, then divides tools cost by that remainder. 25 over 2.5 is 10 per net hour.

The main result comes from cost, hours, and fixes. The automated-task share sits in the grid.

Second example: 40 over 6 is 6.67 per net hour. Third: 90 minutes minus 0.5 hours is 1 hour of fixes beyond the time saved.

The calculator does not turn automation on and does not connect to an account. A comma in 12.5 is read the same way as a period.

Formula

Result = cost ÷ (hours − minutes ÷ 60). At 25, 3 and 30: 25 ÷ 2.5 = 10 per net hour. When net hours are 0 or below, the calculator does not divide.

What these numbers mean

25 over 2.5 is 10 per net hour.

cost, hours, and fixes
Tools cost divided by hours saved minus minutes over 60. In the first example that is 25, 3 and 30.
automated tasks
They sit in the grid. Here 8 of 20 tasks give the share and do not change the cost per net hour.
rate and people
They are optional and sit in the grid. They do not change the main result.

How to use

  1. Enter 20 tasks.
  2. Add 8 automated tasks, 3 hours saved, tools cost 25, and 30 fix minutes.
  3. Click Calculate. The result is 10 per net hour.
  4. Second example: 12, 9, 6, 40 and 0 is 6.67 per net hour. Third: 15, 3, 0.5, 80 and 90 is 1 hour of fixes beyond the time saved.
  5. You can skip the rate and the people count. When you fill them, they appear in the grid and do not change the main result.

  • tasks 20
  • auto 8
  • saved 3 h
  • tools 25
  • fixes 30 min

10 per net hour

Example 2

  • tasks 12
  • auto 9
  • saved 6 h
  • tools 40
  • fixes 0 min

6.67 per net hour

40 ÷ (6 − 0) = 6.67 per net hour.

Example 3

  • tasks 15
  • auto 3
  • saved 0.5 h
  • tools 80
