Frequently asked questions
Egress is data transferred OUT of the cloud to the internet. Inbound (ingress) is usually free, but providers charge per GB for outbound traffic, which can dominate a bill for content-heavy apps.
Subtract any free-tier allowance from your total outbound data, then multiply the remainder by the per-GB egress rate. 1,000 GB with a 100 GB free tier at $0.09/GB costs about $81.
Use a CDN to cache content at the edge, compress responses, keep traffic within the same region/provider, and avoid unnecessary cross-region transfers.
Often within the same region it is free or cheap, but cross-region and cross-AZ transfer can incur charges. Always check the provider’s data-transfer matrix.
Double the traffic, more than double the bill
1,000 GB transferred out, a 100 GB free tier, at roughly $0.09/GB: billable GB is 1,000 − 100 = 900, so cost is 900 × 0.09 = $81 a month, about ₹6,966 at a ₹86/USD rate. Double the traffic to 2,000 GB with the identical 100 GB free allowance, and billable GB rises to 1,900 — pushing cost to $171, more than double the original bill. The fixed 100 GB free tier becomes a shrinking share of a larger total, so its discount effect fades as traffic grows.
The maths is simple — billable GB = total minus free tier, times the per-GB rate — but the impact on a real bill is large, and busy apps serving video, large downloads or media move far more than 1,000 GB in a month. Inbound traffic is typically free on every major provider; it is specifically the outbound direction that adds up on the invoice.
To cut egress, put a CDN in front of static and media content, compress responses, and keep traffic in-region. This tool estimates the egress component only; storage and compute bill separately, so pair this with the storage and instance-cost calculators to see the full monthly picture for an application rather than just its network line item.
Prices as of June 2026 and illustrative (first-tier egress, commonly published rates). Cloud pricing varies by region and changes frequently — always verify current rates on the provider's pricing page before budgeting.
