AWS Lambda pricing
Amazon Web Services · FaaS (request + GB-second) · snapshot captured June 2026
AWS Lambda is priced as faas (request + gb-second). $0.20 per 1M requests + $0.0000166667 per GB-second (x86). Arm/Graviton2 is ~20% cheaper. Billed per 1 ms. Memory is configurable 128 MB-10 GB and sets the GB-second rate. It scales to zero, so you pay nothing while idle. Egress: Standard AWS egress: first 100 GB/month free, then ~$0.09/GB.

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 AWS Lambda 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 (standard aws egress: first 100 gb/month free, then ~$0.09/gb.).

Cost pros & cons
Where AWS Lambda saves money
- Mature, deepest AWS ecosystem (API Gateway, SQS, DynamoDB, EventBridge)
- Generous perpetual free tier (1M req + 400k GB-s/mo)
- Arm/Graviton2 runtime is ~20% cheaper per GB-second
Watch-outs
- Egress, API Gateway and NAT gateway costs add up fast and are billed separately
- Cold starts on infrequently-hit functions
- Per-request + per-GB-second model is hard to predict for bursty traffic
AWS Lambda vs similar platforms
How AWS Lambda compares with related serverless platforms on the headline rates:
| Platform | Model | Per 1M req | Per GB-s | Egress |
|---|---|---|---|---|
| AWS Lambda (this platform) | FaaS (request + GB-second) | $0.20 / 1M | $0.0000167 / GB-s | $0.09/GB |
| Azure Functions | FaaS (Consumption / Flex Consumption) | $0.20 / 1M | $0.000016 / GB-s | varies |
| 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 AWS Lambda cost?
$0.20 per 1M requests + $0.0000166667 per GB-second (x86). Arm/Graviton2 is ~20% cheaper. Billed per 1 ms. Memory is configurable 128 MB-10 GB and sets the GB-second rate. Snapshot June 2026 — verify on the vendor's pricing page.
Does AWS Lambda have a free tier?
Yes — and it renews every month, not just for the first year. 1,000,000 requests/month + 400,000 GB-s/month, perpetual (does not expire after 12 months).
Does AWS Lambda scale to zero?
Yes — AWS Lambda scales to zero, so you pay nothing while it is idle (you are billed only for actual usage). 1M requests + 400,000 GB-s every month, forever (not just 12 months).
What does AWS Lambda charge for egress?
Standard AWS egress: first 100 GB/month free, then ~$0.09/GB. 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 Amazon Web Services'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.
