A 3 h 10 m print on a 5000 mm/s² printer that a slicer predicts at 3 h 02 m comes out at 3 h 08 m with the Prusa MK4 preset; with 62 g of PLA at $22/kg, 120 W at $0.15/kWh and a 40% markup the sale price lands near $9.20.Open the G-code Print Time & Filament Cost Estimator

What is the G-code Print Time & Filament Cost Estimator?
Most G-code time estimators simply divide distance by feed rate, which is far too optimistic because a printer constantly accelerates and brakes. This tool runs a Marlin-style look-ahead planner over every move: it computes junction speeds from the corner angle (junction deviation), applies your acceleration, and integrates the real trapezoidal speed profile of each segment. Choose a preset for your printer class or enter your acceleration, and the estimate lands much closer to the real clock.
Enter the actual time of a similar print once and it computes a personal correction factor, saved in your browser for next time. From the same file you get exact filament length and weight, volumetric flow statistics, and a full cost breakdown: filament, electricity (watts × hours × price), machine wear, labour, a failure allowance and a suggested sale price with markup.

What you get
Junction-deviation planner with your acceleration — not a naive distance ÷ speed.
See the slicer's own estimate and derive a correction factor from a real print.
Length, weight and cost computed from every extrusion move.
Electricity, machine hours, labour, waste and markup in one table.

Questions people ask
How does it estimate time?
A look-ahead planner: junction speeds from corner angles and a trapezoidal profile per segment using your acceleration.
Why differ from my slicer?
Slicers model acceleration/jerk and sometimes your printer's real limits more precisely; use the calibration to align them.
Does it include heating time?
No — only motion and dwell times in the file.
Is my G-code uploaded?
No — parsing runs in a background thread in your browser.
How do I use the G-code Print Time & Filament Cost Estimator?
1. Drop in your .gcode file. 2. Pick a printer preset or enter acceleration and junction deviation. 3. Set filament price, power draw and any labour or markup. 4. Read the time, filament and cost breakdown.
