About CDN Cost Calculator: Bandwidth, Requests & Cache Hits
Estimate CDN bandwidth, request, origin-traffic, monthly, and annual costs using editable rates.
Change the example inputs to match a scenario and review the methodology and limitations before using the result in a decision. Calculations run locally in your browser.
How the calculation works
Origin traffic
Delivered bandwidth × (1 − cache-hit ratio).
Monthly total
CDN bandwidth cost + request cost + estimated origin egress cost.
How to use this tool
- 1Replace the example values with internally consistent inputs.
- 2Review all result cards and any not-applicable state.
- 3Compare multiple scenarios and verify important assumptions independently.
Understanding the result
Higher cache hit ratios reduce the modeled origin traffic but not necessarily CDN delivery charges.
A 100% cache-hit input produces zero—not negative—origin traffic.
Important limitations
- Outputs are planning estimates and do not include every provider, accounting, financing, tax, legal, or operational factor.
- Invalid divisions are shown as not applicable rather than NaN or Infinity.
- Tiered regions, revalidation, purge, shielding, compute, and provider-specific billing are excluded.
