CDN Bandwidth Cost Calculator

CDN bandwidth charges can dominate costs for media-heavy and global traffic. Use this calculator to estimate monthly CDN bandwidth spend using your own $/GB assumptions.

Inputs

CDN bandwidth (GB / month)
CDN price ($ / GB)
Enter your provider’s effective $/GB for the region/path/tier.

Results

Estimated monthly cost
$240.00
Egress
4,000 GB
Price
$0.06 / GB

Example scenario

  • If your CDN serves 4,000 GB/month at $0.06/GB, estimated bandwidth cost is $240/month.

Included

  • Bandwidth-only CDN cost estimate from GB/month and $/GB pricing.
  • Use for planning and comparing pricing tiers/regions.

Not included

  • CDN request fees (use CDN Request Cost Calculator).
  • Origin egress and cache fill traffic (model separately if applicable).

How we calculate

  • Monthly cost = CDN egress GB × price per GB.
  • Enter your provider’s effective bandwidth $/GB (consider region/tier).
  • This page ignores tiered steps, free allowances, and per-request fees unless you model them separately.

FAQ

Is CDN bandwidth the same as origin egress?
Not necessarily. CDN providers bill bandwidth at the edge; origin egress may be separate if the CDN pulls from your origin.
What about request charges?
Many CDNs charge per request (e.g., per 10k). This calculator is bandwidth-only.
How do I estimate GB per month?
You can approximate from throughput or traffic analytics. Use the Units Converter for Mbps → GB/month estimates.
