CloudFront Cost Calculator (bandwidth + request fees)

This CloudFront cost calculator helps you estimate two common CDN line items: bandwidth and requests. Plug in your own $/GB and $ per 10k assumptions, then add them to get a monthly estimate.

1) Bandwidth

Use monthly GB delivered by the CDN edge to end users. If you start from Mbps charts, convert Mbps to GB/month using the Units Converter.

Inputs

CDN bandwidth (GB / month)
Avg throughput: 30.46 Mbps.
Avg throughput (Mbps)
Est 24,624 GB/month.
Pricing mode
Use tiered mode when pricing changes by volume.
CDN price ($ / GB)
Enter your provider's effective $/GB for the region/path/tier.

Estimated monthly cost
$600.00
Egress
10,000 GB
Price
$0.06 / GB

2) Requests

If your provider bills per request (often per 10k or per 1M), estimate monthly requests and apply the rate.

Inputs

Requests (per month)
Avg 114.22 req/sec.
Avg RPS
Est 315,187,200 requests/month.
Pricing unit
Per 1M is 100x per 10k.
Price ($ / 10k requests)
Effective rate: $0.75 / 1M requests
Scenario presets

Results

Estimated monthly request cost
$225.00
Requests
300,000,000
Cost per 1M requests
$0.75

How to get your inputs

  • Inputs: use billing exports, metrics, or logs to get real counts/GB where possible.
  • Units: convert throughput (Mbps) or rates (RPS) into monthly units when needed.
  • Scenarios: build a baseline and a high-usage scenario to avoid under-budgeting.

Result interpretation

  • If bandwidth dominates, focus on cache hit rate and content compression.
  • If requests dominate, review object size, caching strategy, and origin response headers.

Common mistakes

  • Using a single average and ignoring peak/incident scenarios.
  • Double-counting or missing adjacent line items (transfer, logs, retries).

Advanced inputs to capture

  • Bandwidth and request counts are separate cost drivers.
  • Use cache hit rate to estimate origin egress.
  • Apply an effective rate for your regional traffic mix.
  • Add log delivery and invalidations if you use them.

Scenario planning

Scenario Bandwidth Requests Cache hit rate
Baseline Expected Expected Current
Peak High High Lower under surge

Validate after changes

  • Compare your estimate to the first real bill and adjust assumptions.
  • Track the primary driver metric (requests/GB/count) over time.

Example scenario

  • Bandwidth: 10,000 GB/month at your $/GB + Requests: 400M/month at your $ per 10k -> estimate monthly CDN cost.
  • If your workload has many small objects, request fees can become a meaningful part of the bill.

Included

  • Bandwidth estimate from GB/month and $/GB pricing assumptions.
  • Request-fee estimate from requests/month and $ per 10k pricing assumptions.

Not included

  • Origin egress and cache fill costs (model separately if billed).
  • Tiered pricing by region unless you use a blended rate or model scenarios.

How we calculate

  • Total = bandwidth cost + request fees.
  • Bandwidth cost = GB/month x $/GB.
  • Request fees = (requests/month / 10,000) x $ per 10k.
  • If pricing is tiered, use a blended rate or run multiple scenarios and sum.

FAQ

Is this an official CloudFront quote?
No. It's a planning estimate based on the assumptions you enter. Always confirm pricing tiers, regions, and units in the official documentation.
What inputs do I need?
Monthly GB delivered to users and monthly request volume. If you only have throughput or RPS, convert them using the Units Converter and RPS-to-monthly tool.
