Key takeaways
- A hardware crowdfunding budget has at least seven distinct cost lines: platform fees, payment processing, a pledge manager, tooling, certification, freight and duties, and a contingency, on top of whatever engineering is still ahead of you.
- Kickstarter, Indiegogo and Crowd Supply all take roughly 5 percent of funds collected plus separate payment processing, and all three charge nothing if the campaign fails to reach its goal.
- US, UK and EU import rules on reward shipments are all mid-change in 2026, so a budget built on last year’s duty-free thresholds can be wrong by the time rewards ship.
- Engineering fees and manufacturing costs are two different budget lines. A range quoted for first-prototype development is not the cost of reaching a shippable production run.
Crowdfunding a hardware product really costs the campaign’s platform fee (around 5 percent on Kickstarter, Indiegogo and Crowd Supply alike), payment processing on top of that, a pledge manager if you add one after funding, tooling and certification if you haven’t already paid for them, freight and import duty on every reward you ship, and a contingency for the pledges and shipments that don’t go as planned. Most first-time campaign budgets account for the first two and miss the rest.
This is the engineering and fulfillment side of that budget: what each line actually covers, where the published figures agree and disagree, and which figures change often enough that you should re-check them before you launch. It assumes you’re past validating whether to crowdfund at all; our guide to crowdfunding a hardware product covers that broader process.
The line items a first-draft budget usually misses
| Cost line | When it hits | Commonly missed because |
|---|---|---|
| Platform fee | On successful funding | Assumed to be the only fee |
| Payment processing | On successful funding | Quoted separately from the platform fee, easy to miss |
| Pledge manager | After the campaign ends | Not needed until fulfillment planning starts |
| Tooling | Before the first production run | Looks like a one-time cost, but often repeats across revisions |
| Certification | Before a product can ship | Treated as a formality rather than a budget line |
| Freight and duties | Per shipment, per region | Rules differ by destination and change year to year |
| Contingency | Throughout | Cut first when the goal looks tight |
Platform and payment processing fees
The three major hardware crowdfunding platforms price similarly, and all three charge nothing if a campaign fails to reach its goal:
- Kickstarter: 5 percent of funds collected on a successfully funded project, plus payment processing through Stripe, which Kickstarter’s own help pages describe as running roughly 3 to 5 percent depending on the backer’s location and card.
- Indiegogo: 5 percent of the amount collected, plus 3 percent and 20 cents per transaction in payment processing. Indiegogo’s own worked example: $10,000 raised across 100 transactions nets roughly $9,180 after both fees.
- Crowd Supply: a 5 percent crowdfunding fee plus 2.9 percent and 30 cents per transaction in card processing. Crowd Supply also charges a separate 10 percent fee on any post-campaign pre-orders, which a Kickstarter or Indiegogo campaign wouldn’t need to budget for.
These figures reflect each platform’s own fee pages as published in 2026. All three platforms revise fees periodically, so confirm the current rate on the platform’s own page before finalizing a goal.
The pledge-manager line item most budgets miss
A pledge manager is software run after a campaign ends: it collects final shipping addresses, processes add-on or upgrade purchases, re-attempts payment on pledges that failed to collect, and handles late pledges. It is a separate cost from the platform’s own fee, typically a small percentage of the funds it processes on top of whatever the platform already charged, and it is easy to miss in a first-draft budget because it isn’t needed until after the campaign is already funded. If you plan to run one, get its current pricing in writing before you set your goal rather than assuming it’s a rounding error.
Some pledges also never collect: a card expires, a backer changes their mind, or a payment simply fails when the platform attempts to charge it after the campaign ends. Budgeting a contingency for a portion of pledges not converting to shipped rewards is standard practice; treating every dollar pledged as a dollar you will actually collect is the more common mistake.
Engineering costs, if development isn’t finished yet
If your campaign goal still needs to cover finishing the product itself, that engineering cost is a separate line from everything above it, and it scales with how novel the product is. In our experience at Inventornest, for the recent group of first-prototype programs we discussed, the approximate development fee range was USD 8,000 to USD 30,000, with simpler products using established, off-the-shelf functions costing less and new mechanisms or several interacting systems within one product increasing the engineering effort and cost. These are working estimates rather than a calculated median, and they describe the engineering and prototyping phase specifically, not the full cost of reaching production or launch, which is the separate set of lines covered in the rest of this article.
Within that kind of program, our approximate allocation runs roughly 15 percent industrial design, 30 percent electronics schematics and PCB development, 35 percent firmware development, and 20 percent testing and other activities, covering materials, labor and operating expenses for the first prototype but excluding shipping and taxes. The 20 percent testing category is combined rather than broken out further, and it shouldn’t be read as including separately measured mechanical work, certification or manufacturing-transfer costs. A detailed breakdown of hardware development cost generally lives in our guide to hardware product development cost, rather than repeated here.
Tooling: the cost that lands right after a successful campaign
A successful campaign creates an order quantity that a single prototype unit was never built to satisfy, and that’s usually when injection-mold or other production tooling becomes a real line item rather than a future problem. Tooling cost is generally the single largest manufacturing setup expense in the jump from prototype to production, and it scales with cavity count, material and tolerance requirements rather than with any single standard figure. Get a current quote from a toolmaker for your specific part before you set a goal around it, rather than relying on a general industry number, which can be out of date within a year or two.
The number of physical units built during development is also not the number a funded campaign needs to produce. We usually build two physical prototype units during development, one for the client and one retained by our team, with simpler products sometimes allowing five or six and complex or expensive products sometimes limited to one. None of those figures describe a production run sized for hundreds or thousands of backers, which is a distinct manufacturing and tooling decision made after the campaign funds.
Certification
Certification, such as FCC testing for a wireless or electronic product, is its own budget line and one that’s commonly underestimated because it’s assumed to be a quick formality. It’s covered in depth, including current lab-cost ranges, in our guide to FCC certification cost rather than restated here; the short version for a campaign budget is to get a certification quote before setting your goal, not after.
Freight, duties and VAT on every reward you ship
Shipping a campaign’s rewards internationally runs into customs rules that are actively changing in 2026, which makes this the single most volatile line in a crowdfunding budget:
- United States: the de minimis exemption that previously let low-value shipments enter duty-free has been suspended for non-postal shipments under a 2026 Federal Register rule from US Customs and Border Protection, meaning most reward shipments now need a formal or informal customs entry rather than simplified release.
- United Kingdom: import VAT is charged on goods brought into the UK, generally at the same rate that would apply if the goods were sold domestically, per HM Revenue and Customs’ own guidance.
- European Union: the EU abolished its low-value VAT exemption in 2021, so VAT is due on commercial imports regardless of value; its Import One-Stop Shop lets a seller collect VAT at checkout for shipments up to €150, per the European Commission’s own guidance. Separately, the EU removed its own customs duty-free threshold for goods valued at €150 or less starting 1 July 2026, replacing it with a flat €3 per-item customs duty that runs through mid-2028, per the European Commission’s trade guidance.
All three regimes are subject to further change. Treat any duty or VAT figure in this section as a starting point to verify against the relevant customs authority shortly before you ship, not a number to lock into your budget months in advance.
A rough shape for the budget, not a template to copy
We prefer fixed-price proposals for the engineering portion of a program, because a clear financial commitment for a defined scope is more useful to a founder building a campaign budget than an open-ended hourly estimate. Our proposals specify deliverables, exclusions, timelines and payment milestones, and anything outside that agreed scope, including extra prototypes or late design changes, is quoted separately. The same discipline is worth applying to the rest of the campaign budget: price each line item specifically (platform fee, processing, pledge manager, tooling, certification, freight and duties, contingency) rather than folding them into a single round number and hoping it holds.
A related worked example, building a full funding-goal calculation from bill-of-materials cost and minimum order quantity, is covered in our Kickstarter funding goal guide; for proof that the underlying numbers are achievable, our guide to successful hardware Kickstarter campaigns looks at what delivered campaigns actually funded and shipped.
Frequently asked questions
What percentage of a crowdfunding campaign goes to fees?
Roughly 5 percent in platform fees on Kickstarter, Indiegogo and Crowd Supply alike, plus payment processing of about 3 to 5 percent depending on the platform and the backer’s card. A pledge manager, if you add one, is a separate line on top of both.
Is the engineering cost range the same as the full cost of launching a product?
No. A first-prototype engineering fee range covers the design and development phase. Tooling, certification, freight, duties and the campaign’s own fees are separate lines that come later and are not included in that range.
What’s the biggest hidden cost in a hardware crowdfunding budget?
Import duties and VAT on international reward shipments are the most likely to surprise a first-time campaign, because the rules differ by destination and have been actively changing through 2026.
Do I need a pledge manager?
Not every campaign uses one, but if you plan to collect add-on sales, late pledges or updated shipping addresses after funding, budget for its fee as a separate line rather than assuming it’s included in the platform’s own cut.
Should I set my goal to just cover manufacturing, or include fees and contingency too?
Include fees, certification, freight, duties and a contingency in the goal itself. A goal that only covers parts and assembly will fall short the moment any other line item appears.
Do platform fees change often?
They’re revised periodically by each platform, so confirm the current rate on the platform’s own fee page close to when you set your goal rather than relying on a figure from a prior campaign.
Where Inventornest fits
The engineering side of a crowdfunding budget, the first-prototype fee range, the allocation across design, electronics, firmware and testing, and the gap between development prototype quantities and a funded production run, is the part we work through directly with founders. We always prefer to begin with feasibility, whether the idea is simple or complex, because it helps identify risks, clarify the development scope and protect the budget before committing to full engineering. Our crowdfunding product development team can help size that part of the budget before you launch; see completed builds in our portfolio.
