The Monthly page

What the file tells you every month

Every cost the car takes, every wear item and when it is due by kilometres or by date — and one number nobody knows about their own car: what it costs per kilometre over the last twelve months, with fuel consumption against what it should be and repairs as a share of the year.

01 · verdictMoney — this month vs budget, 12 months, how much was repairs

02 · verdictService — what is overdue by km or by date, what is due

03 · verdictFuel — litres per 100 km vs what it should get, fuel per km

Sheets in the workbook

✓Monthly · cost per km, three verdicts, three tasks

✓Costs · every cost; fuel lines with odometer and litres

✓Service · every wear item with km and month intervals — due computed against the odometer

✓Months · spent, fuel, repairs, litres per month

✓Settings · the car, today's odometer, budget, warning windows, expected consumption

How it works

1Set the car up — odometer, budget, warning windows, expected L/100 km — once; update the odometer monthly

2Log every cost — fuel with odometer and litres; the rest as it comes

3Open Monthly — cost per km, three verdicts, three tasks — ten minutes

Who it is for
