Filament Length and Cost Calculator
Your slicer tells you the grams a print uses. Enter it with your spool price to get length and cost.
Result
- Filament length
- 40.2 m
- Material cost
- $2.4
- Full spool length
- 335 m
Densities are typical values and vary slightly by brand and colour. Add failed prints and purge lines to your real cost.
How this calculator works
Length = mass / (density x cross-section area). The cross-section of a filament is pi x (diameter / 2) squared. Cost = grams used / spool grams x spool price.
