How Much Does It Cost to Develop a Hardware Product?

A hardware product costs between roughly $75,000 and $300,000 to develop and reach a first production run through an outside engineering firm, on the figures published across the industry, with simple non-electronic products landing below that and anything cellular, medical or first-of-a-kind landing well above it. The spread is that wide because four independent variables (whether it has a radio, whether it has a battery, how complex the enclosure is, and whether it enters a regulated market) each move the number by tens of thousands of dollars.

Most published estimates answer a different question than the one you are asking. They budget a founder building it themselves, buying their own dev boards and doing their own CAD. This guide budgets an outsourced engagement, and structures every number the way it appears on a real quote.

What a hardware product actually costs, end to end

The distinction that makes a budget legible is the one between money you spend once and money you spend on every unit forever. Get that wrong and your spreadsheet will be out by a factor of ten in one direction or the other.

The four cost buckets

One trap inside NRE is worth knowing before you sign anything. Paying a supplier’s NRE line does not automatically give you transferable ownership of the tooling, fixtures or CAM data it produced. Founders routinely assume that a paid setup fee means they own the stencil and the fixtures and can move them to another factory. That is a contract term, not a default.

Why published ranges are so wide

Two real examples of the same job priced very differently, both from compliance firms selling the service:

• One puts a wireless CE marking job at roughly €1,500 to €3,000
• Another puts the equivalent Radio Equipment Directive work at €10,000 to €60,000

Neither is wrong. The first prices a simple consumer device built on a pre-certified module using harmonized standards and self-declaration. The second prices a complex multi-radio product that needs third-party involvement. Same regulation, same paperwork, twenty times the cost, because the products are not comparable.

Read every published range as a statement about a product you have not seen.

Cost tiers at a glance

Most products fall into one of three bands for an outsourced engagement taken to a first production run. The band is set by what the product contains, not by how big it is.

Cost by product type: IoT, AIoT, physical AI and more

The stage and discipline costs further down apply to every electronic product. What changes between product types is which extra lines appear on the quote, and which costs keep running after launch.

Custom PCB and electronics

Fabricating the board is rarely the expensive part, and manufacturers publish prototype prices openly. OSH Park charges $5 per square inch for a set of three two-layer boards and $10 per square inch for four-layer, so three 100 x 100 mm boards (about 15.5 square inches) come to roughly $78 or $155. Advanced Circuits lists two-layer prototypes at $33 each and four-layer boards at $66 each on its standard specials. The money sits elsewhere:

• Layer count. Moving from two to four layers roughly doubles the per-board price at both manufacturers above, and dense or high-speed designs need the extra layers.
• Board spins. In our experience at Inventornest, we usually need two PCB development iterations. Depending on complexity and the issues found, a project may require four or five.
• Design labor. Schematic, layout and firmware engineering dwarf fabrication cost, which is why the discipline table below carries the larger numbers. Our PCB design services page covers that work, and the factory side is explained in PCB fabrication and assembly.

Connected IoT devices

A radio turns a product into a service, and a service has running costs. A connected device carries every line above, plus these (the IoT product development process shows where each one enters the build):

• The radio path. A pre-certified module or a chip-down design, which changes certification cost more than any other single choice (see the certification table below).
• Companion app and cloud backend. Two software projects that are usually scoped and quoted separately from the hardware.
• Running costs per device. Published pricing gives the shape. AWS IoT Core lists $0.08 per million connection-minutes and $1.00 per million messages in its example region. Hologram lists cellular data at $1 per SIM per month plus $0.03 per megabyte. The Things Stack Cloud lists a LoRaWAN plan at €190 a month covering 1,000 devices. Check current pricing before budgeting.
• Security obligations. The UK’s PSTI regime has applied since 29 April 2024 (no default passwords, a way to report vulnerabilities, a stated update period). EU cybersecurity requirements under Delegated Regulation (EU) 2022/30 have applied to many wireless products since 1 August 2025, and the Cyber Resilience Act adds vulnerability reporting from 11 September 2026 and full application from 11 December 2027. These cost engineering and documentation time rather than fees.

At Inventornest, we advise against connectivity when it adds cost and complexity without solving a meaningful user problem. Where appropriate, we validate the core function first and consider connected features in a later phase. Our IoT device development page covers the connected work itself.

AIoT and edge AI devices

On-device AI adds a compute decision, a data problem and a power problem. The compute choice sets the hardware line, and published prices show how wide it runs:

Jetson figures are from NVIDIA’s published price list. Several of these prices rose during 2026 as memory costs climbed, so treat them as a snapshot. The hardware is usually the smaller part of the AI budget:

• Data and model work. Collecting, labeling and testing training data for your specific sensor and environment, then fitting the model to the chosen chip.
• Power and heat. More compute means a bigger battery or a thermal design, which ripples into the enclosure.
• Dev kit to custom board. A prototype on a development kit often needs a custom carrier board before it can be manufactured.
• Regulation. The EU AI Act applies to some AI systems sold in Europe, and several of its deadlines moved in 2026, so check the current timeline for your use case.

Whether a product needs AI at all is a separate question, covered in AI in IoT devices.

Physical AI and robotics

A product that moves adds three cost lines a static device does not have: actuation, perception and safety. If you are unsure whether your product counts, start with what physical AI means.

• Compute. NVIDIA lists Jetson AGX Orin modules at $1,799 (32GB) and $2,999 (64GB), and Jetson Thor T5000 at $4,999, all at 1,000-unit pricing.
• Perception. Depth cameras start in the low hundreds of dollars (Orbbec lists its Gemini 335 at $264 on its own store), and lidar is usually quote-based.
• Motion. Motors, drivers, encoders and gearboxes, plus the durability testing that anything with moving parts needs.
• Safety. Consumer service robots are addressed by ANSI/CAN/UL 3300, personal care robots by ISO 13482 (CHF 204 to buy), and functional safety by the IEC 61508 series. The standards are cheap to buy; the engineering evidence to meet them is not.

Our physical AI product development page covers how that work is scoped.

Wearables and health products

Small boards, small batteries and skin contact each add cost. The decision with the largest effect is whether the product makes a medical claim.

• Miniaturization. Tight space pushes toward more board layers, custom battery shapes and a custom PCB where a module will not fit.
• Battery. Lithium cells trigger UN 38.3 transport testing, priced in the certification section below.
• Medical or wellness. A wellness product follows consumer electronics rules. A medical device adds FDA filing and annual registration fees, itemized below.

Cost by stage, from idea to first production run

Proof of concept and feasibility

The cheapest stage and the one that saves the most money. Feasibility work runs from about $1,500 for a narrow question to $15,000 or more for a full assessment covering technical, regulatory and cost viability. What you are buying is the answer to whether the physics, the certification path and the target price can coexist. Our guide on assessing product feasibility covers what a proper one includes.

Skipping this stage is how projects discover in month nine that the battery cannot fit, and that discovery costs six figures rather than four.

Prototype and engineering builds

Prototypes split into two kinds that get confused constantly, and the difference between them is the difference between a prototype and an MVP.

• Looks-like models prove form, size and feel. Foam mock-ups start around $100. A finished appearance model runs from roughly $2,000 to $150,000 depending on finish quality.
• Works-like prototypes prove function, and carry your first custom circuit board. Published ranges run from about $2,000 to $250,000, and the spread is almost entirely about how much custom electronics is involved.
• 3D printed parts cost roughly $100 to $1,000 per iteration. Urethane casting costs $250 to $1,500 for the mold and $20 to $50 per part after that, which is why it beats printing past about twenty units. See our guide on how 3D printing is transforming product development for where each process stops making sense.

EVT, DVT and PVT

Nobody publishes credible dollar figures per validation gate, which is itself worth knowing when you read a guide that offers them. What is well documented is the shape of each stage, and you can construct your own number from unit counts and build cost.

Build size is set by the risks each gate has to uncover, not by a fixed count. The way to build your own estimate is unit cost at that volume, multiplied by units, plus the engineering time to analyze the results and respin. The third term is the one founders leave out, and it is usually the largest. Our prototype testing checklist sets out what actually gets tested at each gate.

Tooling and pilot production

Injection mold tooling is the single largest step change in a hardware budget, and the number depends heavily on where the tool is cut. Published figures from a Chinese molder:

Every figure in this section is a supplier’s own price list rather than a market survey, so treat them as the shape of the number and get your own quotes. The same molder reports its pricing runs 40% to 60% below Western equivalents, which is a self-interested claim and not an implausible one. Two cost drivers move these numbers more than anything else:

• Cavity count. Each added cavity adds somewhere between 15% and 50% to the tool, and the right count is set by your annual volume, not your ambition.
• Side actions. Every lifter or slider needed to form an undercut adds roughly $1,500 to $8,000, or 10% to 40% of the mold cost. A part with several can cost more than half again what a simple one costs.

Lead times are the part that wrecks schedules. Standard production tooling runs 45 to 65 days from order to first sample shots. A small four-cavity ABS part takes about five weeks. A large single-cavity part takes eight to nine. Expedite fees add 20% to 35% and buy back only a couple of weeks.

How long the budget takes to spend

Cost and calendar move together, because most of the budget is engineering time. In our experience at Inventornest, these are typical planning ranges:

They should not be read as the time to a first saleable unit, because commercial sale also depends on the remaining production and compliance work. Where the rest of the calendar goes is covered in how long it takes to develop a hardware product.

Cost by engineering discipline

Start from what the work is worth, because it explains the rates you will be quoted. US Bureau of Labor Statistics data for May 2025 puts the median wage for electrical and electronics engineers at $125,040 a year, about $60.12 an hour, and mechanical engineers at $104,110.

Design and engineering firms bill between roughly $100 and $450 an hour. That runs from a little under twice the underlying hourly wage to more than seven times it, and the multiple is not margin alone. It covers benefits, equipment, software licenses, unbilled time, project management and the fact that a firm carries several disciplines you would otherwise have to hire and coordinate yourself.

Offshore engineering runs about $20 to $25 an hour against the $100 to $450 band above. The rate gap is real and so is the coordination cost, and the projects that go badly wrong offshore are usually the ones where nobody owned integration. If you are a technical founder, firmware and electronics work is covered on our hardware engineering for technical founders page.

Inside a single first prototype the split looks different again. In our experience at Inventornest, the approximate allocation for a typical first-prototype program is:

• Industrial design: 15%
• Electronics schematics and PCB development: 30%
• Firmware development: 35%
• Testing and other activities: 20%

That allocation includes materials, labor charges and operating expenses for the first prototype. Shipping and taxes are excluded, the 20% is a combined category, and mechanical work, certification and manufacturing transfer are not separately measured within it or assumed to be included.

Connected products add two software projects the discipline table does not show: the companion app and the cloud backend. Both are priced as software engagements, and both carry hosting and maintenance after launch.

Certification, itemized

Certification is where founders find the largest gap between what they budgeted and what arrives, mostly because they budget government fees and pay private labs.

The FCC charges almost nothing. Under 47 CFR 1.1103, the FCC’s only material equipment-authorization charge is a one-time $35 fee for a grantee code, plus $50 if you file a confidentiality request. The testing is performed by private accredited labs and Telecommunication Certification Bodies, and that is where the money goes. Any guide quoting FCC certification fees in the hundreds or thousands is citing a schedule the FCC removed in its 2020 application-fee order. Certification moved to accredited third-party bodies in stages between 1999 and 2014.

Three things that get missed:

• Bluetooth is a separate bill, and a module does not cover it. The Bluetooth SIG restructured dues and fees effective 1 March 2026. Product qualification at Adopter level (free membership) is $12,000. A Contributing Adopter tier at $3,500 a year for a small company ($16,500 for a large one) discounts the first qualification each membership year to $8,000, which beats the Adopter route on your very first product, and Associate membership discounts every qualification to $6,000, which pays off across a portfolio. Later products reusing the same qualified design carry no further fee. Using a pre-certified radio module cuts your FCC testing cost, and your end product still needs its own Bluetooth qualification under your own membership. Check the current Bluetooth qualification fees before budgeting, because this schedule has moved twice in three years.
• UL is an annual cost, not a one-off. UL Solutions does not publish prices. Its published fee structure includes an annual data maintenance fee, a quarterly-billed certification fee for ongoing use of the mark, and follow-up services with onsite factory inspections. Your budget needs a recurring line.
• FDA filing fees are public and large. For fiscal year 2027 (1 October 2026 to 30 September 2027), a 510(k) submission costs $28,653, or $7,163 for a qualifying small business. A De Novo is $191,020, or $47,755 for a small business. Annual establishment registration is $13,785 regardless of size. Those are filing fees only, before any testing or quality system work, and they rise every October.

Budget a retest. EMC test labs commonly report that around half the products they see fail on the first attempt. No authoritative dataset sits behind that figure, and a failure still adds roughly $2,000 to $10,000 and four to twelve weeks whenever it happens. Pre-compliance scanning at $3,000 to $8,000 is the cheapest insurance in the whole program.

What drives your number up or down

1. A radio. The difference between a self-declared unintentional radiator and a custom chip-down radio is roughly $1,500 to $3,500 against $8,000 to $20,000, and Bluetooth adds its own qualification fee on top. Using a pre-certified module is the single largest cost lever available to you.
2. On-device AI or motion. A compute module, a model to train and a motor to make safe each add their own development lines, set out by product type above.
3. A battery. Lithium cells trigger UN 38.3 transport testing, which consumes samples destructively. Mains power triggers safety certification and its annual fees.
4. Enclosure complexity. Undercuts drive side actions, and side actions drive tooling. A design review before the tool is cut typically pays for itself several times over.
5. A regulated market. Medical, children’s products and anything touching skin or measuring a vital sign change the cost class entirely.
6. Volume. NRE amortization is brutal at low volume. A $600 assembly setup fee adds $120 per board across 5 units and $1.20 across 500.
7. First-of-a-kind versus reference design. Building on an existing reference design can halve the electronics engineering. Inventing something genuinely new cannot be shortcut.
8. Whether it works first time. This is the variable nobody budgets, and the next section is about it.

Costs founders routinely leave out of the budget

The forced redesign. A change after the design is frozen is the most expensive kind, because it lands on work already paid for. It arrives as engineering rework, then re-verification and compliance retesting on top, then whatever the schedule slip costs commercially. A single component going end-of-life late in a program can trigger all three at once.

Component obsolescence. Component sourcing firms report semiconductor lifecycles compressing from over ten years before 2020 to under five for consumer-grade parts, and put a six-layer board respin at $12,000 to $45,000 in engineering alone. Those are trade estimates rather than measured data, and the direction is not in dispute. A product designed today can face a forced redesign before it turns five, and a meaningful share of end-of-life notices never reach every affected customer.

Everything else that lands after the quote:

• Tooling modification after the first shots: $300 to $8,000 per change
• Certification retest following a design change, plus the schedule it costs
• Sustaining engineering and firmware maintenance, commonly 15% to 20% of build cost per year
• Cloud and connectivity for a connected product, as an ongoing per-device cost
• Packaging design, retail packaging, and the drop testing that validates it
• Safety stock, and the working capital tied up in it
• Freight, customs and duties. Rates on electronics have moved repeatedly, so check the current position with USTR and CBP at the time you import rather than trusting any figure published earlier

Where you can cut cost without breaking the product

Every item below lowers the number without removing the thing that proves the product works.

1. Use a pre-certified radio module. It narrows the certification bill toward the connected-device range in the table above, instead of the custom-radio one.
2. Prototype on a reference design or development kit. Move to a custom board once the function is proven, not before.
3. Launch with less connectivity. If the core function works without an app or cloud, a later phase can add it.
4. Stage the AI. Prove the model on a development kit before choosing production silicon.
5. Use soft or bridge tooling first. A single-cavity prototype mold costs a fraction of production steel, per the tooling table above.
6. Keep the enclosure simple. Fewer parts and fewer undercuts mean fewer side actions on the tool.
7. Run pre-compliance scans. Finding an emissions problem before the formal lab is far cheaper than a failed test and a respin.

What not to cut: feasibility, and testing of the product’s essential function. Those are the two places where a saving early becomes a redesign later.

Building it yourself versus budgeting an outsourced engagement

Most cost guides online budget a DIY build. That is a legitimate path and a completely different number, because the largest line in an outsourced quote is labor you are proposing to supply for free.

The honest comparison is not price against price. It is a lower cash number with your time and your risk absorbed invisibly, against a higher cash number with the risk transferred and the schedule enforceable. Founders who compare only the cash numbers consistently underestimate the first column by the value of a year of their own work.

How to turn this into a number you can raise against

Investors do not fund a range. They fund a plan with named line items and a stated point of proof.

1. Fix the specification first. Every unresolved requirement is an unpriced risk, and a firm quoting an unfixed spec is quoting a guess.
2. Price the stage, not the product. Raise to a defined gate (working prototype, or EVT complete) rather than to “launch.” Gates are estimable and launches are not.
3. Separate one-time from per-unit. Show NRE, tooling and certification as capital, and unit cost as the thing that determines whether the business works. Target costing works that unit cost backward from the shelf price, so the bill of materials has a budget before the design is frozen.
4. Carry contingency explicitly. A 20% to 30% contingency is a realistic plan rather than a padded one, and you can justify it from named lines: an EMC retest at $2,000 to $10,000, tooling modification at $300 to $8,000 per change, and the engineering time to analyze a failure and respin. Showing it makes a budget more credible, not less.
5. Name what you have not priced. Duties, sustaining engineering and obsolescence belong in the plan even before you can size them.

Frequently asked questions

How much does it cost to develop a hardware product?

Roughly $75,000 to $300,000 through an outside firm for a connected consumer product taken to a first production run. Simple non-electronic products can come in at $20,000 to $60,000, and cellular, medical or first-of-a-kind products commonly exceed $500,000.

What is NRE and why is it a separate line?

Non-recurring engineering is one-time design and setup cost that is not repeated per unit: engineering labor, CAM setup, fixtures, stencils and test programming. It is separated because it amortizes across volume, and at low volume it dominates your unit cost.

Why is certification so much more expensive for a wireless product?

An unintentional radiator can often self-declare after $1,500 to $3,500 of testing. A custom radio needs full certification through an accredited body at $8,000 to $20,000. A pre-certified module avoids most of that difference on the FCC side, though a Bluetooth product still needs its own qualification with the Bluetooth SIG.

How much does it cost to develop an IoT device?

Expect every engineering line of an electronic product, plus a companion app, a cloud backend and running costs per device for hosting and data. Building on a pre-certified radio module keeps certification nearer the ,000 to ,000 connected-device range than the ,000 to ,000 of a custom radio, and security rules such as the UK PSTI regime and the EU Cyber Resilience Act add engineering and documentation work.

What do most founders forget to budget?

The second attempt. Retesting after a failed EMC scan, tooling modifications after first shots, and the engineering time to analyze test results and respin. EMC labs commonly report around half the products they see failing first time, and that is a schedule cost as well as a cash one.

What does it cost to add AI to a device?

The hardware line is the compute. NVIDIA lists Jetson Orin Nano modules from 9 and the Orin NX 16GB at 9, and Raspberry Pi lists its AI HAT+ 2 accelerator at 0. Many products need only a microcontroller with a small neural processor, and choosing the AI chip for your product early keeps that line small. The larger costs are usually the data and model work, plus the power and thermal design that extra compute forces.

Where Inventornest fits

Inventornest begins with technical feasibility, defines the requirements and then quotes a fixed cost for the agreed development scope, which can cover industrial design, mechanical, electronics and firmware. Our proposals specify deliverables, exclusions, timelines and payment milestones. Our outsourced product development page sets out the full scope, and product design and prototyping covers the earlier stages on their own.
