Estimating Reference
CNC Machining Cost Calculator
Your machine rate, cycle time, setup, material, and margin. The per-part arithmetic every machining quote runs on, with setup amortized over the batch.
The arithmetic of a machining quote
Every machining quote reduces to the same structure: machining time × loaded machine rate, plus setup spread over the batch, plus material, plus tooling, then margin. The number that dominates small batches is setup: two hours of setup on a single part can cost more than the machining itself, which is why per-part price falls so steeply with quantity and why quotes carry quantity breaks.
The loaded rate is the number shops get wrong most often, it must carry the machine (depreciation or lease), the operator fully burdened, power, consumables, maintenance, floor space, and a share of overhead, divided by realistic billable hours, not theoretical ones. And it is per work center: the 5-axis cell and the saw do not share a rate.
This calculator is deliberately your-numbers-in, your-numbers-out: it applies no cost models of its own, the same philosophy behind Mavlon's AI estimating, where AI reads the RFQ package and your own pricing logic produces the quote.
The arithmetic takes seconds. Reading the RFQ takes the day.
Mavlon reads the drawings, specs, and emails, structures every requirement, and drafts the quote from your existing rates and rules.
