Step by step

Values used
Load-balancing and outbound rules = 8 rules; Rules included in the base charge = 5 rules; Base rate for the included rules = 0.0250 USD/hour; Rate per additional rule = 0.0100 USD/hour; Data processed = 5,000 GB/month; Price per GB processed = 0.0050 USD; Standard public IP addresses = 2 addresses; Price per public IP = 0.0050 USD/hour; Billed hours per month = 730 hours
Azure Load Balancer
monthly = base rate × 730 for the first five rules + additional rules × per-rule rate × 730 + data processed × per-GB rate + public IPs × per-IP rate × 730.

How it works

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.

Formula

Azure Load Balancer

monthly = base rate × 730 for the first five rules + additional rules × per-rule rate × 730 + data processed × per-GB rate + public IPs × per-IP rate × 730.

included rules: First five load-balancing or outbound rules covered by the base rate
data processed: Inbound plus outbound bytes handled by the load balancer
public IP: Standard SKU static address, billed hourly even when idle

Frequently Asked Questions

How is Azure Load Balancer calculated?

monthly = base rate × 730 for the first five rules + additional rules × per-rule rate × 730 + data processed × per-GB rate + public IPs × per-IP rate × 730.

Why does Azure Load Balancer matter?

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.
