Cost per kilometre

Type consumption and the litre price. 7 L/100 km and 6.50 give 0,46 zł per km. 6 and 6.20 give 0,37 zł. 9 and 6.50 give 0,59 zł. Standard mode, no A/B compare.

Not TCO and not the other spend-over-mileage card. Here only fuel: (L/100) × price. Service, insurance, and depreciation sit outside the formula.

How it works

Cost per kilometre in this calculator is L/100 km times the litre price, over 100. 7 × 6.50 / 100 = 0.455. The result is 0,46 zł. 6 × 6.20 / 100 = 0.372, the result 0,37 zł. 9 × 6.50 / 100 = 0.585, the result 0,59 zł. Two decimal places.

Consumption is L/100 km and price is per litre with a metric header. This is not mpg and not a gallon. The neighbour gold card divides a receipt by mileage. There is no receipt amount and no odometer here. Fuel for one km only.

A/B compare, reverse mode, and annual km stay off in the examples. Standard mode and two fields remain. Type a % correction or annual km and a note grows beside 0,46 zł. The examples do not do that.

TCO is ownership. Trip fuel cost multiplies litres on a stretch. Here one kilometre of fuel. 0,46 zł times 100 km is 46 zł, but this calculator does not show that product until you type an annual distance.

Type 7 and 6.50, then Calculate. A comma in 6.50 parses. Zero price or zero consumption leaves the result blank. A station sketch, not the full cost of the car.

7 and 6.50 give 0,46 zł. 6 and 6.20 give 0,37 zł. 9 and 6.50 give 0,59 zł. Another price at the same 7 changes the result.

Formula

cost per km = consumption × price / 100

How to use

  1. Leave standard mode on. Do not tick A/B compare.
  2. Type consumption, for example 7. Type price, for example 6.50.
  3. Click Calculate. The result is 0,46 zł.
  4. 6 and 6.20 give 0,37 zł. 9 and 6.50 give 0,59 zł.
  5. Spend over mileage lives on the neighbour card. TCO is separate.

7 L/100 km and 6.50 = 0,46 zł

Cost per km = consumption × price / 100. 7 and 6.50 give 0,46 zł. This is not TCO.

kilometre
The result unit. 7 and 6.50 show 0,46 zł per km. Not the whole stretch.
fuel
The only term in the formula. 6 and 6.20 give 0,37 zł. Service does not enter.
TCO
Full ownership lives on another calculator. 9 and 6.50 give 0,59 zł of fuel only.
