Direct answer: at Azure Bandwidth pricing and the Retail API on 10 November 2026 (USD, excluding tax and discounts), North America/Europe internet egress gives 100 GB free per month; via transit ISP: $0.08/GB for the next 10 TB, $0.065 for 10–50 TB, $0.06 for 50–150 TB and $0.04 beyond 150 TB; via Microsoft Premium Global Network: $0.087 / $0.083 / $0.07 / $0.05. Asia (excluding China)/Australia/MEA ISP is $0.11 / $0.075 / $0.07 / $0.06, South America $0.12 / $0.085 / $0.08 / $0.075. Inter-region: North America/Europe intra-continental $0.02/GB, Asia/Oceania/MEA $0.08, South America $0.16; inter-continental $0.05 / $0.08 / $0.16. At the official 1 TB = 1,000 GB: 10 TB North America $792.00 (premium $861.30), 150 TB $9,392.00 (premium $11,181.30), 500 TB $23,392.00 (premium $28,681.30); South America 10 TB $1,188.00 (premium $1,791.90). Front Door edge egress is separate ($0.083 first 10 TB, $0.066 10–50 TB, $0.057 50–150 TB), and Azure origin-to-Front Door is free; VNet peering, Private Endpoint and ExpressRoute/VPN are different meters.
This guide is for teams responsible for cloud egress, CDN/edge, cross-region data, FinOps, procurement and finance. It separates official prices, editorial calculations and exclusions, covering internet egress tiers, routing preference, Asia/South America premiums, inter-region/inter-continental rates, 1/10/50/150/500 TB TCO, CDN/Front Door/peering/PE comparisons, hidden costs and a 90-day checklist. Prices come from the Bandwidth pricing page, Azure Retail Prices API and Front Door pricing page (10 November 2026). This is not procurement advice.
(1) After 100 GB free, rates vary by region/route: North America/Europe $0.08, Asia $0.11, South America $0.12/GB (ISP); premium routing costs more. (2) Cross-region is not a flat $0.08: North America/Europe intra $0.02, Asia $0.08, South America $0.16; inter-continental $0.05/$0.08/$0.16. (3) CDN/Front Door origin egress is free, but edge egress bills; VNet peering/Private Endpoint/ER are separate meters—don't mix them.
Internet egress: North America/Europe tiers and routing preference
North America/Europe egress gives 100 GB free per month; via transit ISP: $0.08/GB for the next 10 TB, $0.065 for 10–50 TB, $0.06 for 50–150 TB and $0.04 beyond 150 TB. Via Microsoft Premium Global Network: $0.087/$0.083/$0.07/$0.05. At 150 TB, ISP is $9,392 vs premium $11,181.30, a $1,789.30 (19%) gap; at 500 TB the gap is $5,289.30 (22.6%). Routing preference is a performance/path choice, not a free switch—confirm premium is really required.

Asia and South America: same volume, higher price
Asia (excluding China)/Australia/MEA: ISP $0.11/$0.075/$0.07/$0.06, premium $0.12/$0.085/$0.082/$0.08. South America: ISP $0.12/$0.085/$0.08/$0.075, premium $0.181/$0.175/$0.17/$0.16. At 10 TB: Asia ISP $1,089, premium $1,188; South America ISP $1,188, premium $1,791.90. At 150 TB: Asia ISP $11,089, premium $12,788; South America ISP $12,588, premium $25,791.90. User location and source continent matter more than total volume.
| Region/volume | ISP 10 TB | Premium 10 TB | ISP 150 TB | Premium 150 TB |
|---|---|---|---|---|
| Asia/Australia/MEA | $1,089.00 | $1,188.00 | $11,089.00 | $12,788.00 |
| South America | $1,188.00 | $1,791.90 | $12,588.00 | $25,791.90 |
Editorial calculation: official tiers, 1 TB = 1,000 GB, first 100 GB free; excludes tax and discounts. Asia excludes China; other regions follow the official table.
Cross-region/inter-continental: $0.02, $0.08, $0.16
Intra-continental cross-region: North America/Europe $0.02/GB, Asia/Oceania/MEA $0.08, South America $0.16. Inter-continental: North America/Europe to other continents $0.05, Asia/Oceania/Africa to other continents $0.08, South America to other continents $0.16.

TCO: 1/10/50/150/500 TB in North America
North America/Europe ISP: 1 TB $72.00, 10 TB $792.00, 50 TB $3,392.00, 150 TB $9,392.00, 500 TB $23,392.00; premium: $78.30/$861.30/$4,181.30/$11,181.30/$28,681.30. Premium is only $69.30 (8.75%) more at 10 TB, but $1,789.30 (19.0%) more at 150 TB and $5,289.30 (22.6%) more at 500 TB. The larger the volume, the more routing preference costs; confirm premium is necessary, then estimate at the 10/50/150 TB tiers.
| Traffic/month | ISP | Premium | Delta |
|---|---|---|---|
| 1 TB | $72.00 | $78.30 | +$6.30 |
| 10 TB | $792.00 | $861.30 | +$69.30 |

Editorial calculation: official tiers, 1 TB = 1,000 GB, first 100 GB free; excludes tax and discounts. Above 500 TB contact sales.
CDN/Front Door/peering/PE: different paths, different bills
Direct egress uses the tiers above; Front Door edge egress is separate ($0.083 first 10 TB, $0.066 10–50 TB, $0.057 50–150 TB in Zone 1), and Azure origin-to-Front Door is free—useful for acceleration and WAF; CDN is similar, with origin-to-CDN free in specific cases. VNet peering is separate: $0.02/GB intra-region end-to-end, $0.07–0.32 global; Private Endpoint is $0.01/hour + $0.01/GB; ExpressRoute/VPN bills circuits/gateways separately. Decide whether traffic goes to the public internet, another VNet, or PaaS, then pick the meter.
| Path | Rate | Fit | Note |
|---|---|---|---|
| Direct internet egress | $0.04–0.12/GB | Public clients | Region/routing tiers |
| Front Door edge | $0.083/$0.066/$0.057 | Acceleration/WAF | Origin-to-FD free |
| VNet peering | From $0.02 intra | VNet to VNet | Both ends bill |
| Private Endpoint | $0.01/h + $0.01/GB | PaaS private access | Not a public egress replacement |
| ExpressRoute/VPN | Circuit/gateway fees | Hybrid | Egress separate |

Selection matrix and hidden costs
Choose by destination: public clients use direct egress or Front Door/CDN (static-heavy/WAF uses edge); VNet-to-VNet uses peering; PaaS private access uses Private Endpoint; hybrid uses ER/VPN. Seven hidden costs: 100 GB free only once, regional rate differences, premium routing premium, cross-region backup/logs, CDN/FD edge fees, peering at both ends, and ER/VPN circuit fees. 90 days: weeks 1–2 inventory egress volume, source/destination, region and routing preference; weeks 2–4 price direct egress vs FD at 10/50/150 TB; weeks 4–6 identify cross-region backup/log/media; weeks 6–8 add cache/compression/image formats; weeks 8–10 verify FD/peering/PE boundaries; weeks 10–12 reconcile egress, cross-region and edge fees against the bill.
| Scenario | First choice | Check first |
|---|---|---|
| Public static/download | CDN/Front Door | Cache hit, edge fee |
| Public dynamic API | Direct egress/FD | Region, premium routing |
| VNet to VNet | Peering | Intra/global, both ends |
| PaaS private access | Private Endpoint | Hourly + GB |
| Cross-region backup/logs | Local retention/tiering | $0.02–0.16/GB |
| Hybrid connectivity | ER/VPN | Circuit/gateway fees |

FAQ
How is Azure egress billed?
Internet egress gives 100 GB free per month; North America/Europe ISP is $0.08/$0.065/$0.06/$0.04 in tiers, premium $0.087/$0.083/$0.07/$0.05; Asia/South America are higher. Ingress is generally free; cross-region is $0.02–0.16/GB.
What does 10 TB of egress cost?
North America/Europe ISP $792.00, premium $861.30; Asia ISP $1,089, premium $1,188; South America ISP $1,188, premium $1,791.90. 1 TB = 1,000 GB, first 100 GB free.
Why is the 150 TB gap so large?
Because of tiers: ISP 150 TB is $9,392, premium $11,181.30, a $1,789.30 (19%) gap; at 500 TB the gap is $5,289.30 (22.6%). Premium routing buys path/performance, not a required feature.
How is cross-region traffic billed?
Intra-continental: North America/Europe $0.02, Asia/Oceania/MEA $0.08, South America $0.16; inter-continental: $0.05/$0.08/$0.16. 10 TB is $200/$800/$1,600 (intra) and $500/$800/$1,600 (inter-continental).
Is Front Door/CDN cheaper?
Not necessarily. Front Door edge is $0.083 for the first 10 TB, $0.066 for 10–50 TB, $0.057 for 50–150 TB—slightly above direct egress at the first tier, but origin-to-FD is free and it adds caching/acceleration/WAF; it pays off for static-heavy or edge-security workloads.
How does it differ from VNet peering?
Peering is a separate meter for VNet-to-VNet traffic (from $0.02/GB intra-region end-to-end, $0.07–0.32 global), not the internet egress/inter-region data transfer in this article; don't mix them.
Can Private Endpoint eliminate egress?
It provides private PaaS access ($0.01/h + $0.01/GB), keeping supported service traffic private; public internet access still needs egress/NAT, so it is not a blanket replacement.
How do I reduce cost?
Five steps: (1) compress/images/cache to cut bytes; (2) serve static via CDN/FD and place dynamic workloads near users; (3) move only necessary cross-region data and keep local copies; (4) avoid premium routing unless required; (5) reconcile the 100 GB free tier, region/routing and cross-region tiers against the bill.
