Charts on Atlas Pricing

    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 Charts Settings 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.

    Once the 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:

    1. 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 GB free tier.

    2. 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 GB free tier.

    3. 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 GB of data over the month.

      The first 1 GB is free, and the remaining 2 GB is billed at $1.00 per GB, resulting in a total cost of $2.00 for the month.
