Kubernetes Pricing

Worker nodes are charged per second.

For example, consider a cluster with:

• Three worker nodes that cost $100/month ($0.00004134/second)
• No autoscaling
• 27 days, 1 hour, and 20 seconds (2,336,420 seconds) of usage

The total cost would be 3 * $0.00004134/second * 2,336,420 seconds = $289.73.

At minimum, we charge node pools for 60 seconds of usage or $0.01 per node in the pool, whichever is greater. For node pools with varying number of nodes with different time spans, we aggregate the usage first.

For example, if a worker pool has 3 nodes with 20 seconds of usage each earlier in the month, then 15 seconds of usage later in the month, the aggregate usage is 35 seconds. For billing, we round this usage up to 60 seconds. If that results in a bill of less than $0.03 ($0.01 per node), we round the bill up to $0.03.

At most, we charge node pools for 28 days of usage per month. If there are more than 28 days in the month, we charge for the 28 days (672 hours) with the highest usage, and don’t charge for any additional usage.

For example, consider a cluster that:

• Runs continuously through a month with 31 days (744 hours)

• Has a node pool that varies between 10 and 25 nodes

• Uses worker nodes that cost $100/month ($0.00004134/second)

A node pool’s fixed size over a time is called a span. To calculate the total cost, we aggregate node pool spans with the same number of nodes over the month, and sort in descending order:

The 672 hours billing cap is reached in the second span with 10 nodes. While the usage is for a total of 744 hours (31 days), we bill you only for 672 hours (28 days). Thus, the total node pool cost is $372.06 + $297.65 + $223.20 + $223.24 + $223.24 + $148.82 + $107.15 = $1595.28.
