How Much Does CNC Machine Monitoring Cost?
Subscription price is only part of the cost. Here is how monitoring is priced, what hardware and setup add, how many machines to start with, and a simple way to decide whether it is worth it for your shop.
The honest answer is: it depends on your machines more than on the software. A shop with modern controls that already speak MTConnect can monitor for little more than a subscription. A shop with older controls needs adapters or sensors first, and that is where costs grow.
This guide breaks the cost into its parts so you can estimate your own number — and decide whether it is worth it.
The real cost of monitoring is not the subscription. It is the hardware your machines need to share data, plus the time your team spends turning data into changes.
The five parts of monitoring cost
1. Software subscription
Most vendors charge per machine per month. Some charge per user or by plant. Many do not publish prices and require a sales call.
2. Connectivity hardware
- MTConnect already available: often nothing beyond a network connection and a PC.
- MTConnect available as a control option: may require purchasing or enabling the option through your dealer.
- Older or proprietary controls: an adapter, edge gateway, or sensor kit per machine.
3. Setup and onboarding
Some vendors include it. Others charge onboarding or installation fees, sometimes significant ones. Self-install products shift this to your own time.
4. IT and network
Network drops to machines, VLAN or firewall changes, and — for cloud platforms — security review for outbound connections.
5. Your team's time
The cost most often ignored. Someone has to review the data daily and drive changes. Without that, everything else is wasted.
Typical cost scenarios
| Scenario | What drives cost | Rough shape |
|---|---|---|
| Modern controls with MTConnect, self-install, local software | Subscription only | Lowest. Can start free. |
| Mixed fleet, some adapters needed | Subscription plus adapters per older machine | Moderate, grows with older machines |
| Cloud platform with gateways and onboarding | Subscription plus hardware plus fees, often with an annual contract | Highest upfront |
| Sensor-only monitoring on legacy machines | Sensor kit per machine plus subscription | Low data depth for the money |
Ask every vendor for the total first-year cost at your machine count, including hardware, onboarding, and contract length.
What FEAI Machine Monitor costs
FEAI publishes its prices. You pay by machine, with unlimited users, no installation fee, and no required hardware when machines already provide MTConnect.
| Plan | Machines | Monthly | Annual | Effective per machine per month |
|---|---|---|---|---|
| Free | 2 | $0 | $0 | $0 |
| Shop | 5 | $99 | $990 | about $20 |
| Growth | 10 | $199 | $1,990 | about $20 |
| Scale | 25 | $399 | $3,990 | about $16 |
| Pro | 50 | $699 | $6,990 | about $14 |
| Enterprise | 50+ | Contact | Contact | — |
Is CNC machine monitoring worth it?
Use a simple break-even test:
- Estimate the value of one spindle hour on your busiest machines. Your shop rate is a reasonable proxy.
- Estimate recoverable hours. First-week monitoring data commonly reveals hours of waiting and gaps per machine per week. Assume you recover only a fraction.
- Compare with total monthly cost.
Example: a 10-machine shop at a $95 shop rate. If monitoring helps recover just one hour per machine per week, that is 10 hours × $95 × about 4.3 weeks = roughly $4,100 a month in capacity against a $199 subscription. Even with far more conservative assumptions, the subscription is rarely the deciding factor — follow-through is.
Put your own numbers into the downtime cost calculator and the utilization calculator.
When monitoring is not worth it (yet)
- Machines cannot expose data, and adapters are not in the budget
- Nobody will review data or act on it
- The shop is not capacity-constrained and machines wait for work anyway
How many machines should you monitor first?
Start small and deliberate:
| Shop size | Start with | Why |
|---|---|---|
| 1–5 machines | 2 machines | Prove the data, build the habit |
| 6–20 machines | Bottleneck plus 2–4 others | Find the constraint and compare |
| 20+ machines | One cell or department | Contain rollout, then expand by area |
Choose machines that connect easily, carry the most load, or cause the most arguments. Expand when supervisors start asking for the other machines — that is the signal the habit has formed.
Questions to ask any vendor
- What is the total first-year cost for my machine count, including hardware and onboarding?
- Is there a contract term, and what happens to my data if I leave?
- Which of my specific controls can you read today, and how?
- Do you charge per user?
- Can I start with two machines without a contract?
- Where is my data stored?

FAQ
How much does CNC machine monitoring software cost per machine?
Pricing varies widely by vendor and model. Many cloud platforms quote per machine per month, often with hardware and onboarding fees, and many require a sales call for a quote. FEAI Machine Monitor publishes its prices: free for 2 machines, then $99 per month for 5 up to $699 per month for 50.
Are there hardware costs?
If your machines already provide MTConnect, often none beyond a Windows PC. Older machines may need adapters, sensors, or gateways, which add cost per machine.
Is CNC machine monitoring worth it?
Compare the value of recovered spindle hours with the total cost. If monitoring helps recover even one hour per machine per week on busy machines, the math usually works. Verify with a pilot.
How many machines should I monitor first?
Start with two to five, including your bottleneck. Expand once the data is trusted and someone reviews it daily.
Should I monitor every machine?
Eventually most shops monitor every machine that has meaningful load, but there is no need to start there. Prioritize bottlenecks and high-value machines.
What hidden costs should I watch for?
Integration and IT time, adapters for older controls, onboarding fees, multi-year contracts, and the internal time to review data and act on it.
