With AWS IoT SiteWise, you only pay for what you use with no minimum fees or mandatory service usage. You are billed separately for usage of Messaging, Data Processing, Data Storage, and SiteWise Monitor. This approach provides you with billing transparency because you only pay for the specific AWS IoT SiteWise resources you use.
Estimate your monthly bill using the AWS IoT SiteWise Calculator.
Pricing Detail
Messaging
Messages transport equipment data and computed data to, from, and within AWS IoT SiteWise. Messaging is metered by number of messages ingested and retrieved by querying or publishing. A message can be ingested through a PUT API, or generated by a computation over equipment data. A message can be retrieved by a property update notification published to AWS IoT Core, or as a response to a query request.
Data Processing
You can create production metrics such as Operational Equipment Efficiency (OEE) using mathematical and statistical computations in AWS IoT SiteWise. Data Processed is metered by number of computations run.
Transforms and metrics: You can use a built-in library of operators and functions in AWS IoT SiteWise to create two different types of custom computations - transforms and metrics. AWS IoT SiteWise continuously computes each transform and metric whenever the underlying data is updated.
Auto-computed aggregates: AWS IoT SiteWise automatically computes a set of commonly used aggregates such as average, sum, and count over multiple time periods (e.g., 1 min, 1 hour) for equipment data, transforms, and metrics. For each message ingested, these aggregates are metered as a single computation.
Data Storage
Once data is in the cloud, AWS IoT SiteWise stores equipment and computed data in a managed time series database which automatically scales with your data usage and storage. AWS IoT SiteWise monitors the size of your storage continuously to determine your storage charges.
SiteWise Monitor
SiteWise Monitor provides managed web applications for interacting with operational data from devices and equipment that send data to AWS IoT SiteWise.

Example 1
An industrial production line is sending data to AWS IoT SiteWise in US East (Virginia) region. The production line includes 10 pieces of equipment, each of which reports 1 measurement every second. You configure AWS IoT SiteWise to collect this measurement data and upload to AWS Cloud. The monthly AWS IoT SiteWise charges are estimated as follows:Usage SummaryMessagingNumber of measurements per equipment = 1 measurement per equipment
Frequency of message ingestion = 1 message per second per measurement
Number of messages ingested in a month = 1 message / second / measurement * 1 measurement / equipment * 10 equipment * 86,400 seconds / day * 30 days / month = 25,920,000 messages per monthTotal number of messages ingested per month = 25,920,000 messages per month = 25.92 million messages per month
Data Processing
Auto-computed aggregates
Number of aggregate computations per message = 1 computation per message ingested
Total number of messages ingested per month = 25,920,000 messages per month
Total number of aggregate computations per month = 1 computation / message * 25,920,000 messages / month = 25,920,000 computations = 25.92 million computations per monthTotal computations per month = 25.92 million computations per month
Data Storage
Equipment data
Number of measurement messages per month = 25,920,000 messages per month
Size of each message = 150 bytes per message (assuming each message ingested is 150 bytes)
Storage per month = 25,920,000 messages per month * 150 bytes / message * 1 GB / (1024^3 bytes) = 3.62 GB per month*Auto-computed aggregates
SiteWise stores all auto-computed aggregates. The storage used by auto-computed aggregates depends on the number of aggregates and time-intervals over which they are calculated. In the example above, six auto-computed aggregates calculated over three time intervals (1-minute, 1-hour, 1-day) will result in 0.37 GB per month of data stored. To learn more about how storage used by auto-computed aggregates is estimated, see this calculator.Storage from auto-computed aggregates = 0.37 GB per month*
Total data stored per month = 3.62 GB (from Equipment data) + 0.37 GB (from Auto-computed aggregates) = 3.99 GB per month*
* This data reflects the data storage volume at the end of the first month.

Example 4
To the Example 3, you now add a dashboard using SiteWise Monitor which shows 10 graphs to help monitor equipment performance. Each graph shows 1 measurement aggregate (aggregated over a 1-minute interval) and 5 of your plant operators monitor these graphs during their 8-hour shifts. The additional monthly usage and charges are estimated as follows:Usage Summary
Messaging
Your SiteWise monitor dashboard automatically refreshes every 5 seconds to help ensure that you are visualizing data close to real-time. Assuming that you are monitoring graphs over a 1-hour window, whenever the dashboard refreshes, all data points plotted on that 1-hour window get refreshed. So, for each graph showing a 1-minute aggregate, 60 total data points get fetched upon every refresh through messages. As each of these messages can carry 50 data points, the total messages retrieved can be estimated as follows:Number of messages retrieved per refresh per graph = ceiling((60 data points / refresh / graph) / (50 data points / message)) = 2 messages per refresh per graph
Number of messages retrieved across all graphs per refresh = 2 messages / refresh / graph * 10 graphs = 20 messages per refresh
Number of messages retrieved across all users per month = (20 messages / refresh) * (1 refresh / 5 seconds) * 3600 seconds / hour * 8 hour shift / day / user * 30 days / month * 5 users = 17,280,000 messages per month
Additional number of messages retrieved per month = 17,280,000 messages per month = 17.28 million messages per month
SiteWise Monitor
Number of unique active users per month = 5 plant operators = 5 users per monthBilling Summary
Messaging
Additional messaging usage from SiteWise monitor per month = 17.28 million messages
Monthly charges for messaging = 8.64 million messages * $1.00 per million messages = $17.28 per monthSiteWise Monitor
SiteWise Monitor charges = $10.00 per active user per month
Number of active users per month = 5 users
Monthly charges for SiteWise Monitor = 5 users * $10.00 per active user per month = $50 per monthAdditional Monthly Bill for SiteWise Monitor
Additional monthly charges = $17.28 + $50.00 = $67.28 per month
