Data Egress Cost Calculator
Data egress can be a major driver of cloud spend. Use this calculator to estimate monthly egress cost with your own pricing assumptions.
Inputs
Data transfer (GB / month)
Price ($ / GB)
Enter your provider’s effective $/GB for the region/path/tier.
Results
Estimated monthly cost
$225.00
Egress
2,500 GB
Price
$0.09 / GB
Tips
- Model multiple scenarios: baseline month vs peak month.
- Consider a CDN: it can reduce origin egress and shift cost structure.
- Watch for tiering and minimum charges in provider pricing.
Example scenario
- If you send 2,500 GB/month and your effective price is $0.09/GB, estimated cost is $225/month.
Included
- Bandwidth-only cost estimate from transferred GB and $/GB pricing.
- Works for internet egress, service egress, or any scenario where you know an effective $/GB.
Not included
- Tiered pricing steps and free allowances (unless you reflect them in your effective $/GB).
- Per-request fees and other service-specific charges.
How we calculate
- Monthly cost = egress GB × price per GB.
- Enter your provider’s effective $/GB for the region/path/tier you expect.
- This page ignores free allowances, tiered steps, and rounding unless you model them in the inputs.
FAQ
Why does egress pricing vary so much?
Egress pricing often depends on destination (internet vs cross-region), tiered usage, service (CDN vs origin), and region.
GB vs GiB: which unit should I use?
Cloud billing often uses decimal GB (1 GB = 1,000,000,000 bytes). Some tooling shows GiB (binary). Use the Units Converter to translate.
Does this include request fees or CDN costs?
No. This tool estimates bandwidth-based egress only.
