4 × 2 − 4 = 4. Distance this week is 4 × 6 = 24.
Trips saved by combining errands
The calculator uses the numbers you enter: trips this week and jobs on one outing. 4 trips with 2 jobs each is 4 saved versus 1 job per outing. Distance, planning minutes, and fuel sit in the grid.
The calculator does not plan the route and does not read a fuel meter. Distance, planning minutes, and fuel sit in the grid. An hourly rate is optional and does not change the main result. Shared car: extra cost of sharing one car.

How it works
The calculator multiplies trips by jobs per outing, then subtracts the trip count. 4 × 2 − 4 = 4 saved. Distance, planning minutes, and fuel sit in the grid.
The main result comes from trips and jobs per outing. Distance, planning, and fuel do not change the saved-trip count. An hourly rate is optional and does not change the main result.
Second example: 2 trips with 4 jobs each is 6 saved. Third: 8 trips with 1 job each is 0 saved.
The calculator does not plan the route and does not read a fuel meter. A comma in 12.5 is read the same way as a period.
Formula
Result = trips × jobs per outing − trips. At 4 and 2: 8 − 4 = 4. Distance, planning minutes, and fuel sit in the grid. An hourly rate is optional.
What these numbers mean
4 trips with 2 jobs each is 4 saved.
- jobs per trip
- Tasks finished on one outing. At 4 trips and 2 jobs that is 8 jobs this week. Versus 1 job per outing, 4 trips are saved.
- errand trips
- Outings in a week. The calculator subtracts them from the total job count. At 4 and 8 the result is 4.
- fuel
- Monthly transport cost. It appears in the grid and does not change the saved-trip count.
How to use
- Enter 4 trips and 2 jobs per outing.
- Add distance 6, planning 15, and fuel 90. Those numbers sit in the grid.
- Click Calculate. The result is 4 saved.
- Second example: 2, 4, 4, 20 and 50 is 6 saved. Third: 8, 8, 1, 5 and 180 is 0.
- You can skip the hourly rate. When you fill it, the value of planning time appears in the grid and does not change the main result.
