Charts on Atlas is metered based on the volume of data
transferred from the Charts web server to web browser clients.
MongoDB provides each Charts instance with a free
1 GB of
data transfers per month. You can view your Charts instance's
monthly data usage in the Data Usage page.
The free usage tier provides approximately 500,000 chart renders over a month. However, this number may vary based on the types of charts being rendered. A number chart or a bar chart with few bars typically consumes less data, while a scatter chart with many data points or a large table could consume more.
1 GB of free data usage has been consumed, MongoDB bills
Charts data transfers at a fixed rate of $1.00 per GB.
In addition, any applicable Atlas data transfer fees apply, as per
the Data Transfer Fees section of the
Atlas Pricing page.
Charts is hosted on AWS
us-east-1 region, and
uses this region to calculate the fees.
The following examples show the expected monthly charge for different usage scenarios. Consider:
A Charts instance with 5 users, each of whom refreshes a 10-chart dashboard once an hour during business hours. This results in about 8,000 renders over the month, and easily falls within the
1 GBfree tier.
A dashboard on a large-screen display with 20 charts set to refresh every 5 minutes, all 24 hours of the day. This results in about 300,000 renders over the month. Assuming these charts are not abnormally large, this scenario also falls entirely within the
1 GBfree tier.
A large chart embedded on a web page that receives 10,000 views per day, resulting in 300,000 renders over the month. This chart takes roughly five times as much data to render compared to a typical chart, and consumes
3 GBof data over the month.
1 GBis free, and the remaining
2 GBis billed at $1.00 per GB, resulting in a total cost of $2.00 for the month.
