Model egress spending with tiers, fees, and taxes. See totals instantly for any workload size. Export results, share budgets, and avoid surprise bills later.
| Scenario | Volume (GB) | Free (GB) | Rate / GB | Discount | Tax |
|---|---|---|---|---|---|
| Small app | 500 | 0 | 0.09 | 0% | 0% |
| Streaming burst | 6,000 | 100 | 0.08 | 5% | 10% |
| Global delivery | 25,000 | 0 | Tiered | 12% | 0% |
Egress cost begins with outbound data volume in gigabytes. The calculator derives billable data by subtracting any free allowance and applying a redundancy factor. Values above 1.00 model duplicated traffic from retries, mirroring, or multi-region delivery. Base cost is then estimated using a flat rate or tier bands, producing an effective price per GB.
Tiered pricing changes the blended rate when usage crosses thresholds. In this model, the first tier size is billed at Tier 1, the next equal block at Tier 2, and remaining usage at Tier 3. As volume grows, the blended rate often falls. Compare effective rate between flat and tiered scenarios to spot the breakpoints that matter.
Discounts reduce base charges before tax, so the subtotal equals base minus discount amount. Taxes or VAT are applied to that subtotal to produce the total monthly cost. If your invoices apply taxes differently, treat this estimate as directional. For budgeting, keep discount assumptions conservative and note that special routes, partner networks, or regions may price outside standard terms.
The 12-month projection compounds the current total using a monthly growth rate. With 0% growth, the projection equals twelve times the monthly total. Positive growth increases later months more than early months. This helps model migrations, new features, or expanding user bases, and it highlights when egress could overtake compute or storage as a primary operating expense.
Use outputs to prioritize engineering and procurement work. Lower billable GB through compression, caching, and CDN offload. Reduce redundancy by localizing delivery and limiting cross-region transfers. Track effective rate and total cost monthly, and export CSV or PDF snapshots for reviews, variance analysis, and audit-ready documentation. Recheck rates whenever contracts renew annually.
Data egress is outbound traffic leaving a provider’s network boundary, such as downloads to the internet or transfers to other regions. Providers typically price it per GB, with different rates by destination, region, and route class.
Redundancy models duplicated bytes caused by retries, mirroring, multi-region replication, or parallel delivery paths. If every GB is effectively sent twice, a factor of 2.00 approximates the increased billable volume and cost.
Use tiered inputs when your pricing sheet discounts higher usage levels. Enter the tier size and the three rates that apply as volume grows. The calculator will blend the bands into one effective rate for easier comparisons.
The projection sums monthly totals across 12 months. Month one equals today’s total, and each later month is multiplied by (1 + growth rate). With 0% growth, the projection becomes twelve times the monthly total.
Yes. The calculator subtracts the discount from base charges, then applies tax to the discounted subtotal. If your jurisdiction taxes differently, treat the output as a planning estimate and adjust assumptions to match invoices.
Common levers include caching and CDN offload, compressing payloads, minimizing cross-region transfers, and choosing cheaper routes or regions. Track effective rate and billable GB separately to see whether savings come from engineering or pricing.
