This free calculator is the basic version; the real QuoteForge quote reads your actual CAD and drawing, so it is far more accurate.
- Reads your real STEP geometry and 2D drawing — tolerances and GD&T included, via AI
- Runs automated DFM (design-for-manufacturability) checks
- Prices from YOUR shop’s real machines, rates and margins — not generic defaults
- Produces a branded PDF quote in minutes, and handles multi-part RFQs
This basic estimator can’t see your part’s real geometry, tolerances or finish callouts — QuoteForge can.
Free trial includes 15 parts — no credit card required.
Frequently asked questions
How accurate is this free estimate?
It’s a ballpark range based on the material, dimensions, quantity and complexity you enter — typically the right order of magnitude, but it can’t see your actual part geometry, tolerances or drawing callouts. For an accurate, bindable quote, upload your STEP file and drawing to QuoteForge.
Do I need to create an account?
No. This estimator is completely free and requires no signup, login or file upload.
Why is the price a range instead of one number?
Machining cost depends on details this quick calculator can’t see — exact feature geometry, thin walls, deep pockets, thread callouts and more. The range reflects that uncertainty; QuoteForge’s full quote engine removes it by reading your actual files.
What happens when I click "Start your free trial"?
You’ll be taken to QuoteForge, where you can upload a STEP file and PDF drawing and get an accurate, machine-ready quote in minutes — your first 15 parts are free.
Does this replace getting a real quote from a machine shop?
No — treat it as a starting point for budgeting, not a binding price. For a quote you can actually order against, use QuoteForge or contact a shop directly.
