About this tool
What the Cloud Egress Cost Estimator does
Cloud providers charge for data leaving their network, usually in falling price tiers after a free allowance. This calculator applies a tiered price list to your monthly transfer volume and compares the bill with a flat CDN rate.
Formula
- Billable GB = monthly TB × 1,024 − free allowance
- Cost = sum over tiers of GB in tier × tier price
- Blended price = cost ÷ total GB
Worked example
Using the starting values in the calculator above:
| Input | Value |
|---|---|
| Data out per month | 20 TB |
| Free allowance | 100 GB |
| Price, first 10 TB | $0.09 |
| Price, next 40 TB | $0.09 |
| Price, next 100 TB | $0.07 |
| Price, above 150 TB | $0.05 |
| CDN price for comparison | $0.02 |
| Result | Value |
|---|---|
| Monthly egress cost | $1,784 |
| Annual egress cost | $21,402 |
| Blended price per GB | $0.09 |
| Same volume via CDN | $410 |
| Monthly difference | $1,374 |
How to read the result
The default tiers follow the shape of common public cloud list prices. Replace them with your provider’s current rates and region.
Serving static assets through a CDN, compressing responses and keeping traffic inside one region are the usual ways to cut egress bills.
