Estimate data transfer and egress costs
Cloud providers and content networks charge for outbound data transfer, often called egress, by the gigabyte, and these charges can become a significant part of a bill. This calculator estimates the cost from the volume of data, the price per gigabyte, and any free allowance that is deducted before billing. It shows the billable amount, the monthly cost and an annualised figure so you can gauge the yearly impact.
Enter the data in megabytes, gigabytes or terabytes, and the tool converts to a common unit before applying the price.
Why egress costs matter
Egress pricing is a frequent source of surprise cloud bills, especially for media-heavy sites, backups that leave a provider, and applications that move data between regions. Estimating the cost up front helps with budgeting, comparing providers, and deciding whether a content delivery network or caching layer would pay for itself by reducing transfer.
Real pricing often uses tiers, where the per-gigabyte rate falls as volume rises, and rates differ between regions and destinations. Use a representative average rate for a quick estimate, and check your provider's tiered pricing for an exact figure. All calculation happens locally in your browser.

Frequently Asked Questions
What is data egress?
Egress is outbound data transfer leaving a cloud provider or network. Most providers charge for it per gigabyte, while inbound transfer is often free.
How is the cost calculated?
The free allowance is subtracted from the total data, and the remaining billable gigabytes are multiplied by the price per gigabyte.
Does it account for pricing tiers?
It uses a single flat rate for a quick estimate. Real bills may use tiers where the rate drops at higher volumes, so check your provider for exact figures.
What is a typical price per GB?
Rates vary widely by provider, region and destination, commonly from a few cents to around ten cents per gigabyte. Use your provider\'s published rate.
Why is reducing egress important?
Egress can dominate cloud costs for data-heavy workloads, so caching, compression and content delivery networks that cut transfer can save significant money.
