Model storage, retrieval, operations, and egress precisely. Review classes, locations, retention, and transfer impacts clearly. Plan budgets confidently using transparent inputs, outputs, and examples.
Results appear above this form after submission. Use your own contract or SKU values when your billing account differs from list pricing.
| Scenario | Class | Location | Stored GB | Retrieval GB | Egress GB | Class A | Class B |
|---|---|---|---|---|---|---|---|
| Web app media | Standard | Regional | 5000 | 300 | 800 | 250000 | 5000000 |
| Backup vault | Coldline | Dual or multi-region | 20000 | 100 | 150 | 50000 | 400000 |
| Archive records | Archive | Regional | 80000 | 20 | 50 | 10000 | 80000 |
Storage cost = Stored GB × storage rate.
Class A cost = (Class A operations ÷ 1000) × Class A rate.
Class B cost = (Class B operations ÷ 1000) × Class B rate.
Retrieval cost = Retrieval GB × retrieval rate.
Egress cost = Sum of tiered transfer bands for destination region.
Tag cost = Number of tags × 0.005.
Early deletion estimate = Stored GB × storage rate × remaining minimum-duration share.
Monthly total = Storage + operations + retrieval + egress + tags + Autoclass + early deletion.
Next month forecast = Current total − current storage cost + forecast storage cost.

These inputs reflect common list-pricing patterns. Exact billed rates can differ by location, negotiated contract, destination, feature usage, and invoicing currency.
It estimates monthly and annual object storage spending using stored volume, request counts, retrieval volume, transfer out, tags, retention, and a simple growth forecast.
Each class balances price and access speed differently. Frequent access usually favors Standard, while long-term data can benefit from Nearline, Coldline, or Archive.
Class A usually covers writes, listings, copies, and changes. Class B usually covers reads, metadata checks, and similar lower-cost access requests.
Nearline, Coldline, and Archive often carry minimum storage durations. Removing data too early can trigger a charge for the unused portion.
This model treats retrieval as free when Autoclass is enabled, but adds a small management charge. Review your exact bill settings before approving budgets.
No. Multi-region and dual-region storage usually costs more because the service provides broader geographic placement and resiliency benefits.
Yes. You can change the currency symbol in the form. The calculator still uses USD list-rate assumptions unless you customize the source code.
Use it for planning, comparisons, and internal review. Official invoices can differ because of SKUs, discounts, taxes, transfer paths, or contract pricing.
