Product development for a physical product runs $5K to $500K+. Here are the five real cost drivers, industry price ranges by complexity, and what tooling adds.
Developing a physical product — from sketch to a validated, manufacturable design — typically costs somewhere between $1,500 and $15,000, or more for products that include electronics, and the honest answer is "it depends" on five variables: part count and complexity, how many design iterations you need, which prototyping method proves the design, how much testing or certification the product requires, and who's billing the engineering hours. None of those variables are mysterious. Here's how each one moves the number, what the industry actually charges, and where tooling — a separate cost most people lump in by mistake — fits.
What actually drives the cost
Part count and complexity. A single-material bracket or enclosure is a few CAD hours. A multi-part assembly with moving joints, stacked tolerances, and mixed materials is a different job entirely — more analysis, more interference checks, more iterations before it's release-ready.
Design iterations. Every round of "build it, test it, fix it" costs engineering hours plus a new prototype. Two rounds is normal for a simple part; five or six is normal for anything with mechanisms or electronics.
Prototyping method. FDM 3D printing runs roughly $50–$500 per part and is fine for form/fit checks. SLA or SLS gets closer to production material properties for $100–$800 per part. CNC-machined prototypes, especially in metal, run $200–$3,000+ per part but behave like the real thing under load. Urethane casting from a soft tool ($1,500–$5,000 for the mold) gets you 10–50 production-like parts at $50–$300 each — useful for pilot runs before committing to hard tooling.
Testing and certification. A product with no electronics might need drop testing and not much else. Add a battery, an antenna, or a motor and UL, FCC, or CE testing is likely — often $5,000–$30,000 and several weeks of lead time on its own, stacked on top of the engineering.
Who's doing the work. Outsourced mechanical design and engineering is commonly billed in the $75–$250/hour range industry-wide, depending on the firm's overhead, location, and how specialized the work is. A fixed-fee quote is really that hourly range multiplied by an hours estimate — which is why scope creep, not the rate, is usually what blows up a budget.
Typical ranges by complexity
| Product type | Design & engineering | Prototype cost (per unit) | |---|---|---| | Simple, single-material part | $5,000–$25,000 | $50–$2,000 | | Multi-part mechanical assembly | $25,000–$100,000 | $200–$5,000 | | Electromechanical (electronics + firmware) | $100,000–$500,000+ | $2,000–$50,000 |
These are industry-wide figures, not a quote — actual numbers move with region, iteration count, and how tightly the spec is defined going in. CADmore's own product development engagements typically run $1,500–$3,000 for simpler parts, $3,000–$8,000 for standard products, and $8,000–$15,000 for complex products, plus $6,000–$9,000 more for most products that include electronics.
Tooling is a separate line item
Design and engineering gets you a validated, manufacturable design. It does not get you production — that's tooling: molds, jigs, fixtures — and it's usually the single biggest number in the whole process. A simple single-cavity prototype mold runs $1,000–$6,000. A production-grade, multi-cavity mold for a complex part can run $30,000–$100,000+. Tooling gets committed after the design is locked, which is exactly why the prototyping stage exists: a $2,000 mistake caught in a 3D-printed prototype is a $2,000 mistake. The same mistake caught after a $60,000 mold is already cut is a $60,000 mistake.
Why who does the design matters to the number
A design firm that also owns a factory has a built-in reason to spec designs around equipment it already owns, even when a different material or process would run cheaper for the customer. CADmore doesn't run production. Prototypes get built in-house to validate the design — using prototyping methods matched to what the design needs to prove out, priced as part of the overall product-development engagement rather than as a separate line item — and production then goes through the customer's own manufacturer or CADmore's partner network. That structure means DFM recommendations get made on cost and performance, not on keeping a production line full.
If you're starting from an existing part instead of a blank sheet — improving a competitor's product, or working from a legacy component with no drawings — CADmore's short-range 3D scanning starts at $260 and typically takes 8–10 business days to turn into usable CAD. Standard design engagements run as fast as 24 hours for small jobs, typically 6–8 business days for full projects. CADmore prices projects on a fixed fee scoped to the job rather than billing by the hour, with typical ranges running from $150–$300 for a straightforward 2D drawing conversion up through the complexity-based product-development tiers above for full projects. Tens of thousands of projects have been submitted through CADmore, spanning single brackets to full electromechanical assemblies — the same complexity range this article breaks down.
Getting an actual number
Ranges are useful for budgeting; they're not a quote. The fastest way to turn "it depends" into a real number is to put the actual part or CAD file in front of an engineer. CADmore's paid consultation ($100) reviews your concept or existing design and comes back with a scoped estimate instead of a range — start a project, book the consultation, or just reply with what you're building.
Frequently asked questions
How much does it cost to develop a physical product from idea to a working prototype?
Industry-wide, a simple single-material part typically runs $5,000–$25,000 in design and engineering, plus $50–$2,000 per prototype. A multi-part mechanical assembly runs $25,000–$100,000. An electromechanical product with firmware and certification testing often runs $100,000–$500,000 or more. Where a specific project lands depends on part count, iteration count, and testing scope.
What's the difference between product development cost and tooling cost?
Development cost covers design, engineering, and prototyping — the work that proves a design is manufacturable. Tooling cost is separate: it's what a manufacturer charges to build the molds, jigs, or fixtures needed to mass-produce that design, and it typically isn't paid until after the design is locked. Tooling can range from roughly $1,000 for a simple single-cavity prototype mold to $100,000+ for a complex, multi-cavity production mold.
Why do quotes from different design firms vary so much for the same product?
Two things move independently: rate and scope. Outsourced mechanical design is commonly billed in the $75–$250/hour range industry-wide. The bigger swing is scope — how many design iterations are included, whether DFM review and prototype builds are bundled in, and whether the firm is also trying to sell you its own manufacturing capacity.
Does a product development firm need to also manufacture the product?
No. A firm that also runs a factory has a built-in incentive to design around equipment it already owns, even when a different material or process would run cheaper for the customer. CADmore builds validation prototypes in-house but doesn't run production — that goes through the customer's own manufacturer or CADmore's partner network — so material and process choices get made on cost and performance, not on keeping a production line full.
What's the fastest way to get an actual cost number instead of an industry range?
Put the real part or CAD file in front of an engineer. CADmore's paid consultation ($100) reviews a concept or existing design and returns a scoped estimate instead of a range.
