Transfer volume & rates

Directional egress model — edit rates to match your provider price list.

Cross-cloud transfer (GB/month) Replication, ETL, or chatty APIs between clouds.

2,500

Internet egress (GB/month) Public internet egress from cloud to users or partners.

8,000

CDN egress (GB/month) Edge delivery volume (often cheaper than origin egress).

20,000

Region pair profile Presets adjust default $/GB — you can still edit rates below. Cross-cloud rate ($/GB) Internet egress rate ($/GB) CDN rate ($/GB) Monthly cloud spend ($) — optional If known, shows egress as % of bill.

Directional estimate only — not a provider quote. Edit rates to match contracts.

How the model works

Category cost = GB/month × editable $/GB for that category.
Region pair preset updates default rates (same / cross-region / multicloud).
Monthly total = cross-cloud + internet + CDN costs.
% of bill = monthly total ÷ known cloud spend × 100 (when spend > 0).

All math runs in your browser. Validate with a pilot month of metering.

FAQ

How does the egress cost estimator work?

Enter monthly GB for cross-cloud transfer, internet egress, and CDN. Pick a region-pair profile (or keep defaults) and edit unit rates. The model sums monthly egress dollars and optionally shows % of your known cloud bill.

Why do region pairs matter?

Inter-region and inter-cloud transfer rates vary widely. Same-region private peering is cheaper than public internet across continents. The preset adjusts default $/GB for a typical pair class.

Are the default rates accurate?

Defaults are directional averages for planning — not a quote. Edit unit rates to match your provider price list or negotiated contract.

What about ingress?

Most hyperscalers do not charge ingress the same way as egress. This estimator focuses on egress and CDN egress, which usually dominate surprise bills.

How do I reduce egress spend?

Colocate chatty services, cache at the edge, compress payloads, prefer private interconnects, and avoid chatty cross-cloud sync. Architecture tips appear in the results panel.

Is this a binding cost forecast?

No. Use it to catch hidden transfer costs before architecture lock. Validate with provider pricing calculators and a pilot month of metering.
