Free job shop calculators for machining rates and quotes.



ShopQuote Flow is a collection of browser-based calculation utilities designed for small machine shops and CNC job shops. Estimating machining work often relies on messy spreadsheets or opaque commercial quoting software, making it hard to see which assumptions drive the final bid. ShopQuote Flow addresses this issue by presenting clear, visible calculations for job pricing without requiring software demonstrations or subscriptions.
The platform focuses on transparent shop economics. Instead of using automated black-box pricing, it helps machinists and owners structure their own rates, cycle times, setup costs, and scrap allowances. All computations run directly inside the browser, meaning private cost data and operational numbers never leave the local machine.
By standardizing how shops handle capacity, target margins, and batch sizes, the tool allows estimators to replace broken spreadsheets with consistent formulas. It also includes methods to compare initial estimates against completed work so shops can adjust future bids based on actual run data.
ShopQuote Flow is built for precision manufacturing businesses that need practical bidding numbers without complex software overhead:
A CNC machine shop owner uses the tool to figure out an accurate hourly rate. By entering building rent, utility bills, employee overhead, and machine capacity, the calculator gives a baseline break-even rate alongside a profitable billable rate based on 70 percent machine utilization.
An estimator working on an aerospace part RFQ calculates quantity breaks for 10, 50, and 250 units. The tool separates upfront programming and fixture setup from the recurring unit run time, helping the shop offer realistic volume discounts without giving away machine time.
A fabrication shop reviews a completed manufacturing run that failed to meet profit expectations. By checking the initial quote against the actual hours logged on the mill, the team pinpoints whether the margin loss came from slow cycle times or unbudgeted tooling wear.
ShopQuote Flow is completely free to use. There are no paid subscription tiers, paid upgrades, or usage limits, and all calculators and templates can be accessed without creating an account.
Do I need to create an account to use the calculators?
No registration or sign-up is required. You can load the site and use every calculation tool immediately.
Is my shop data uploaded to a server?
No. All calculations run strictly inside your web browser, ensuring your private rates, costs, and customer quantities stay on your device.
How does the platform determine a shop rate?
The system evaluates your total annual cost pool, expected machine hours, and billable capacity utilization to generate a break-even rate and a recommended rate with a profit margin allowance.
Can I export my quotes into my own files?
Yes. The platform provides an editable spreadsheet template with visible formulas that you can download and modify for internal job tracking.
