A rough monthly estimate from how you actually use the equipment: enter each device's power, the hours it runs, and a duty cycle (the share of that time the elements or burner are firing to hold temperature). Start from the presets, then tune to your bill. Nothing is sent anywhere — this runs entirely in your browser.
These are ballpark estimates. Real draw depends on insulation, ambient temperature, and how hard you're working the glass. Use your actual utility bill to calibrate the duty cycles until the total matches, then trust the mix.

Documenting your shop's components and part numbers makes these numbers easy to fill in — the power draw is on the nameplate.
