Pricing Examples
Monthly compute charges
The monthly compute price is ¥0.000113477 for every GB-second used and the free tier provides 400,000 GB-s.
Total compute (seconds) = 3M * (1s) = 3,000,000 seconds
Total compute (GB-s) = 3,000,000 * 512MB/1024 = 1,500,000 GB-s
Total compute – Free tier compute = Monthly billable compute GB- s1,500,000 GB-s – 400,000 free tier GB-s = 1,100,000 GB-s
Monthly compute charges = 1,100,000 * ¥0.000113477 = ¥124.82
Monthly request charges
The monthly request price is ¥1.36 per 1 million requests and the free tier provides 1M requests per month.
Total requests – Free tier requests = Monthly billable requests
3M requests – 1M free tier requests = 2M Monthly billable requests
Monthly request charges = 2M * ¥ 1.36/M = ¥2.72
Total monthly charges
Total charges = Compute charges + Request charges = ¥124.82 + ¥2.72 = ¥127.54 per month
Monthly compute charges
The monthly compute price is ¥0.000113477 per GB-s and the free tier provides 400,000 GB-s.
Total compute (seconds) = 30M * (0.2sec) = 6,000,000 seconds
Total compute (GB-s) = 6,000,000 * 128MB/1024 = 750,000 GB-s
Total Compute – Free tier compute = Monthly billable compute seconds
750,000 GB-s – 400,000 free tier GB-s = 350,000 GB-s
Monthly compute charges = 350,000 * ¥0.000113477 = ¥39.72
Monthly request charges
The monthly request price is ¥1.36 per 1 million requests and the free tier provides 1M requests per month.
Total requests – Free tier request = Monthly billable requests
30M requests – 1M free tier requests = 29M Monthly billable requests
Monthly request charges = 29M * ¥1.36/M = ¥39.44
Total compute charges
Total charges = Compute charges + Request charges = ¥39.72 + ¥39.44 = ¥79.16 per month
Function 1
128MB of memory, executed 25M times in one month, runs for 200ms each time
Total compute (seconds) = 25M * (0.2sec) = 5M seconds
Function 2
448MB of memory, executed 5M times in one month, runs for 500ms each time
Total compute (seconds) = 5M * (0.5sec) = 2M seconds
Function 3
1024MB of memory, executed 2.5M times in one month, runs for 1 second each time
Total compute (seconds) = 2.5M * (1sec) = 2.5M seconds
If you ran these functions, your charges would be calculated as follows:
Monthly compute charges
Amazon Lambda normalizes the total compute time to GB-s and then sums the total across all functions
Function 1 (GB-S) = 5M seconds * (128MB/1024) = 625,000 GB-s
Function 2 (GB-S) = 2.5M seconds * (448MB/1024) = 1,093,750 GB-s
Function 3 (GB-S) = 2.5M seconds * (1024MB/1024) = 2,500,000 GB-s
Total monthly compute usage (GB-S) = 4,218,750 GB-s
The monthly compute price is ¥0.000113477 per GB-s and the free tier provides 400,000 GB-s.
Monthly charged compute usage = Total monthly compute usage – Free tier usage
Monthly charged compute usage = 4,218,750 – 400,000 = 3,818,750 GB-s
Monthly compute charges = 3,818,750 * ¥0.000113477 = ¥433.34
Monthly request charges
The monthly request price is ¥1.36 per 1 million requests and the free tier provides 1M requests per month.
Total requests – Free tier requests = Monthly billable requests(25M+5M+2.5M) requests – 1M free tier requests = 31.5M Monthly billable requests
Monthly request charges = 31.5M * ¥1.36/M = ¥42.84
Total Monthly Charges
Total charges = Compute charges + Request charges = ¥433.34 + ¥42.84= ¥476.18 per month
Provisioned Concurrency Pricing
You can enable Provisioned Concurrency for your Lambda functions for greater control over the performance of your serverless applications. When enabled, Provisioned Concurrency is designed to keep functions initialized and hyper-ready to respond in double-digit milliseconds. You only pay for the amount of concurrency that you configure and for the period of time that you configure it. When Provisioned Concurrency is enabled for your function and you execute it, you pay for Requests and Duration based on the prices below. If the concurrency for your function exceeds the configured concurrency, you will be billed for executing the excess functions at the rate outlined in the Amazon Lambda Pricing section above. To learn more about Provisioned Concurrency, visit the documentation.
Provisioned Concurrency is calculated from the time you enable it on your function until it is disabled, rounded up to the nearest 5 minutes. The price depends on the amount of memory you allocate to your function and the amount of concurrency that you configure on it.
Duration is calculated from the time your code begins executing until it returns or otherwise terminates, rounded up to the nearest 1ms. The price depends on the amount of memory you allocate to your function.
The Lambda free tier, if available, does not apply to functions that have Provisioned Concurrency enabled. If you enable Provisioned Concurrency for your function and execute it, you will be charged for Requests and Duration based on the price below.
| Price in Amazon Web Services China (Beijing) region, operated by Sinnet | Price in Amazon Web Services China (Ningxia) region, operated by NWCD | |
|---|---|---|
| Provisioned Concurrency | ¥ 0.0000407741 for every GB-second | ¥ 0.000030536 for every GB-second |

| Duration | ¥ 0.0000951387 for every GB-second | ¥ 0.0000712498 for every GB-second |
The prices for Duration and Provisioned Concurrency depend on the amount of memory you allocate to your function. You can allocate any amount of memory to your function between 128MB and 10,240MB, in 1MB increments. The table below contains a few examples of the price per 1ms associated with different memory sizes.

Monthly compute charges
The monthly compute price is ¥0.000113477 per GB-s and the free tier provides 400,000 GB-s.
Total compute (seconds) = 70M * 1 second = 70M secondsTotal compute (GB-s) = 70M * 256MB/1024MB = 17.5M GB-s
Total compute – Free tier compute = Monthly billable compute GB- s17.5M GB-s – 400,000 free tier GB-s = 17.1M GB-s
Monthly compute charges = 17.1M GB-s * ¥0.000113477 = ¥1940.46
Total charges
Total charges = Provisioned Concurrency charges + Total Request charges + Total Compute charges
Total charges = ¥340.78 + (¥40.8 + ¥93.84) + (¥851.08 + ¥1940.46) = ¥3266.96
Example 4: Let’s assume you allocated 1024MB to your function and enabled Provisioned Concurrency on it for two hours. The concurrency that you configured was 1,000. Due to a burst in demand, the function reached a concurrency level of 1,200 several times during these two hours. For the remainder of the time, the concurrency stayed under 1,000. You executed the function 1.2M times during the two hours and it ran for 1 second each time. Of the 1.2M executions, 1M used Provisioned Concurrency and 200,000 did not. Let’s also assume that you have already used up all available requests and duration included in the free usage tier. Your charges would be calculated as follows:Amazon Web Services China (Ningxia) region, operated by NWCD
Provisioned Concurrency charges
The Provisioned Concurrency price is ¥0.000030536 per GB-s
Total period of time for which Provisioned Concurrency is enabled (seconds) = 2 hours = 7,200 seconds
Total concurrency configured (GB): 1000 * 1024MB/1024MB = 1000 GB
Total Provisioned Concurrency amount (GB-s) = 1000 GB * 7,200 seconds = 7.2M GB-s
Provisioned Concurrency charges = 7.2M * ¥0.000030536 = ¥219.86
Request charges for Provisioned Concurrency when usage is under 1,000 concurrency
The monthly request price is ¥1.36 per 1 million requests.
Monthly request charges = 1M * ¥1.36/M = ¥1.36
Compute charges for Provisioned Concurrency when usage is under 1,000 concurrency
The compute price is ¥0.000113477 per GB-s
Total compute duration (seconds) = 1M * 1 second = 1M seconds
Total compute (GB-s) = 1M seconds * 1024MB / 1024MB = 1M GB-s.
Total compute charges = 1M GB-s * ¥0.000113477 = ¥113.48
Monthly request charges for requests over the 1,000 concurrency level
The monthly request price is ¥1.36 per 1 million requests.
Monthly request charges = (1.2M – 1M) * ¥1.36 / M = ¥0.27
Monthly compute charges for compute over the 1,000 concurrency level
The monthly compute price is ¥0.000113477 per GB-s.
Total compute (seconds) = 200,000 * 1 second = 200,000 seconds
Total compute (GB-s) = 200,000 seconds * 1024MB/1024MB = 200,000 GB-sMonthly compute charges = 200,000 GB-s * ¥0.000113477 = ¥22.7
Total charges
Total charges = Provisioned Concurrency charges + Total Request charges + Total Compute charges
Total charges = ¥219.86 + (¥1.36 + ¥0.27) + (¥113.48 + ¥22.7) = ¥357.67
* Duration charges apply to code that runs in the handler of a function as well as initialization code that is declared outside of the handler. For more details, see the Lambda Programming Model documentation.
Additional Charges
You may incur additional charges if your Lambda function utilizes other Amazon Web Services services or transfers data. For example, if your Lambda function reads and writes data to or from Amazon S3, you will be billed for the read/write requests and the data stored in Amazon S3.
For details on Amazon Web Services service pricing, see the pricing section of the relevant Amazon Web Services service. Links to pricing for some of the commonly used services are listed below.
