Filament is only one part of the sum
A part can look cheap when you only count the grams it uses. Electricity, printer wear, working time and finishing all come out of your pocket too.
To work out the cost of PLA or PETG filament, divide the price per kilo by one thousand and multiply by the grams used. The 3D printing calculator does this for every filament you enter.
Gestor 3D brings these expenses together in a single result, so you are less likely to sell without noticing that your margin has disappeared.
