Hi @MrFlinstone
Azure VPN Gateway is billed on an hourly basis, depending on the gateway type and SKU that you use. It's important to note that the cost of a VPN Gateway is based on the gateway type and the amount of time that gateway is provisioned and available.
For Point-to-Site (P2S) VPNs specifically, there are additional charges for VPN gateway hours, data transfer out, and the maximum number of concurrently connected devices (tunnels). However, idle sessions shouldn't significantly impact your costs, as they are not actively transferring data.
Up to 128 connections you will not be charged, after that you will need to pay : $0.01/hour per connection per connection
