Why MakerCalc

Most 3D-printing cost tools stop at filament by the gram. MakerCalc prices a print the way a workshop does — material, electricity and machine wear by the hour, your own labor, hardware and packaging, a failure-rate allowance and a real profit margin. Features competitors put behind a monthly PRO tier — filament library, printer profiles, quote history, batch pricing — are free here, because they are just storage.

Everything is computed locally in your browser: your filament library, printer profiles and saved quotes live in local storage, the whole app works offline once loaded, and a quote can be shared as a single link that opens fully editable on any device.
