With AWS X-Ray, there are no upfront fees or commitments. You pay only for what you use, based on the number of traces recorded, retrieved, and scanned. A trace represents a request to your application and may include multiple data points, such as for calls to other services and database access. The maximum size of a trace is 500 KB. Trace data is retained for 30 days from the time it is recorded at no additional cost.
Perpetual Free Tier
- The first 100,000 traces recorded each month are free.
- The first 1,000,000 traces retrieved or scanned each month are free.

Pricing example
If you have an application which receives 2,000 incoming requests per hour and you’re using a 10% sampling rate, then your cost would be calculated as follows:
Traces Scanned per Month = 100 queries x 200 traces per hour x 31 days = 620,000 traces
Traces Retrieved per Month = 100 queries x 50 traces per query x 31 days = 155,000 traces
Total Traces Retrieved/Scanned per Month = 155,000 traces + 620,000 traces = 775,000 traces
Billable Traces Retrieved/Scanned per Month = 775,000 traces - 1,000,000 traces in free tier = 0 traces
Monthly Traces Retrieved and Scanned Charges = 0 traces * $0.0000005 = $0
In addition, let’s assume you have enabled X-Ray Insights on any or all X-Ray groups.
X-Ray Insights Traces Processed
Traces Recorded per Month = 2,000 requests per hour x 24 hours x 31 days x 10% = 148,800 traces
Monthly Insights Traces Processed Charges = 148,800 traces * $0.000001 = $0.15
Your total cost per month for using AWS X-Ray equals $0.24+ $0.15 = $0.39.
