How to Use the Lambda vs Workers Calculator
-
STEP 01Input your projected monthly request volume (e.g. 25,000,000 requests) and average execution latency (e.g. 65 ms).
-
STEP 02Specify memory allocation (128 MB to 2,048 MB) and architecture (AWS Graviton2 ARM64 vs x86_64).
-
STEP 03Inspect side-by-side cost breakdown including request pricing, GB-seconds compute, and egress bandwidth.
-
STEP 04Export detailed JSON billing report or copy annual savings summary.
Frequently Asked Questions (Lambda vs Workers Calculator)
How does Cloudflare Workers eliminate egress bandwidth costs?
Unlike AWS Lambda which charges $0.09 per GB for data transfer out to the public internet beyond the first 100 GB, Cloudflare Workers operates directly on Cloudflare's global edge network with $0 egress fees. For data-intensive APIs and media streaming, this single difference often reduces infrastructure bills by 60%–90%.
What is the difference between AWS Lambda GB-seconds and Cloudflare Workers CPU time?
AWS Lambda bills for entire wall-clock execution duration rounded up to the nearest millisecond, meaning you pay for idle I/O time while waiting for external databases or third-party APIs. Cloudflare Workers Paid only bills for actual CPU execution time ($0.02 per 1M CPU milliseconds), allowing I/O-bound requests to wait at zero additional compute cost.
When does AWS Lambda make more sense than Cloudflare Workers?
AWS Lambda is advantageous when workloads require custom Linux binaries, Docker container images up to 10 GB, GPU acceleration, execution runtimes longer than 15 minutes, or native VPC integration with legacy internal AWS services.
