Azure Functions pricing
Microsoft Azure · FaaS (Consumption / Flex Consumption) · snapshot captured June 2026
Azure Functions is priced as faas (consumption / flex consumption). Classic Consumption: $0.20 per 1M executions + $0.000016/GB-s (1M + 400k GB-s free). Flex Consumption: $0.40 per 1M executions + $0.000026/GB-s (250k + 100k GB-s free) and adds always-ready instances priced separately. It scales to zero, so you pay nothing while idle. Egress: First 100 GB/month outbound free, then standard Azure bandwidth rates.

Worked example
A small API doing 1,000,000 requests/month, each running ~200 ms at 256 MB of memory (≈50,000 GB-seconds/month):
On Azure Functions this works out to about $0/month of compute after the free tier — the whole workload fits inside the free allowance. Egress and any platform minimum are extra (first 100 gb/month outbound free, then standard azure bandwidth rates.).

Cost pros & cons
Where Azure Functions saves money
- Deep Azure + Microsoft 365 / Entra integration
- Two free grants (Consumption and Flex Consumption)
- Flex Consumption adds always-ready instances and faster scaling
Watch-outs
- Two different consumption models (classic vs Flex) with different rates and free grants
- Always-ready instances on Flex have no free grant and bill separately
- Egress beyond 100 GB billed separately

|---|---|---|---|---|
| Azure Functions (this platform) | FaaS (Consumption / Flex Consumption) | $0.20 / 1M | $0.000016 / GB-s | varies |
| AWS Lambda | FaaS (request + GB-second) | $0.20 / 1M | $0.0000167 / GB-s | $0.09/GB |
| Scaleway Serverless Functions | FaaS + containers (EU, request + GB-s) | $0.17 / 1M | $0.0000055 / GB-s | varies |
| Cloudflare Workers | Edge FaaS (request + CPU-ms) | $0.30 / 1M | n/a | Free |
| Google Cloud Run | Serverless containers (vCPU-s + GiB-s + request) | $0.40 / 1M | $0.0000025 / GB-s | varies |
| Google Cloud Functions | FaaS (now on Cloud Run model) | $0.40 / 1M | $0.0000025 / GB-s | varies |
Frequently asked questions
How much does Azure Functions cost?
Classic Consumption: $0.20 per 1M executions + $0.000016/GB-s (1M + 400k GB-s free). Flex Consumption: $0.40 per 1M executions + $0.000026/GB-s (250k + 100k GB-s free) and adds always-ready instances priced separately. Snapshot June 2026 — verify on the vendor's pricing page.
Does Azure Functions have a free tier?
Yes — and it renews every month, not just for the first year. Consumption plan free grant: 1,000,000 executions + 400,000 GB-s/month. Flex Consumption free grant: 250,000 executions + 100,000 GB-s/month, then $0.000026/GB-s + $0.40/1M executions.
Does Azure Functions scale to zero?
Yes — Azure Functions scales to zero, so you pay nothing while it is idle (you are billed only for actual usage). Consumption plan: 1M executions + 400,000 GB-s/month free. Flex Consumption: 250,000 executions + 100,000 GB-s/month free.
What does Azure Functions charge for egress?
First 100 GB/month outbound free, then standard Azure bandwidth rates. Egress is one of the most overlooked serverless costs, so model your outbound data when comparing platforms.

Source & accuracy
Figures are a dated snapshot from Microsoft Azure's pricing page (snapshot captured June 2026). The worked example is a transparent calculation over those inputs (see methodology). Serverless pricing is volatile and varies by region, memory tier and discounts — verify current prices on the vendor's page before relying on them. This is an informational comparison, not a quote.
