Cost a Standard Load Balancer from its rule count, processed data and the public IP addresses attached to it.
A Standard Load Balancer bills a flat hourly rate that covers the first five rules, an incremental rate for every rule beyond that, and a per-GB charge on all data processed. Inbound NAT rules and health probes are free, but each Standard public IP attached to the frontend is a separate hourly meter. Rule sprawl is the hidden cost here — a per-port rule set for a hundred services costs far more than one HA-ports rule doing the same job, and the per-GB data charge makes the load balancer a real line item at scale; confirm the current rates for your region in the Azure pricing calculator.
