By adjusting the input data in this example, you can calculate for yourself how quickly your purchase returns. Apart from purely a matter of finances you will also buy for yourself sense of independence and that is for many people priceless.
Data contained in this model were obtained from one user In Czech Republic, for which I thank him. So this data correspond to this specific user, for another users it will be different because you will have another price for filling, another distances, another bottle volume, etc., etc. Each person value own time diferently , so I used only a statistical average wages ( in Czech republic ).
Price for filling bottles in filling station: = 0,72 USD/l x 7l =5,04 USD+ extra charges when filling up 7l 1,4 USD =
6,44 USD/per 7 liter bottle
5,96 Euro/per 7 liter bottle
Filling station is at a distance around 23Km x2 = 46km x 0,156 USD/km ( the average price per kilometer )
Transport cost =7,2 USD
Transport cost =6,67 Euro
Time need to get to filling station 40min = 1h 20min + 10 min spend at filling station = 1,5h x Median of net wages = 735,72/month / 160h/month = 4,56 USD/ hour approximately 4 USD per hour
Time spent 1,5 hour = 6 USD
Time spent 1,5 hour = 5,56 Euro
Price for filling is 6,44 USD / 5,96 euro
Transport cost is 7,2 USD / 6,67 Euro
Time cost 6 USD / 5,56 Euro
Total = 20 USD per bottle 18,5 Euro per bottle
Price for 7L bottle filling ( elektricity ) with Altaros 1,5 kW x 4hour x 0,16 USD/kWh = almost 1 USD
Otto had filled his bottle of 7 liters on average 3 times a month and used hand pump when needed.
With our compressor currently fills around 6 bottles per month.
Return of purchase cost for Otto if he fill 3 time per month is:
20 USD /bottle x 3 = 60 USD – 3x 1USD (electricity for altaros compresssor) = 57 USD/month
Compressor cost is 639 USD / 57 = 11,21 month.
From example is obvious that with performance of 3 filled bottles per month would be his purchase price for the compressor returned in less than one year.
If he fill 6 bottles per month like he do with compressor now then compressor cost would be back in half year.
