Object ingest, retained tiers, and replicated capacity
Object ingest, retained tiers, and replicated capacityDaily object volume fills the retention window before compression and stored copies determine forecast capacity and cost.
Cloud Object Storage Cost monthly costForecast month is horizontal and modeled storage, access, and egress cost is vertical.

How to use Cloud Object Storage Cost Calculator
- Enter measured daily object growth and the active retention policy.
- Use a realistic compression or deduplication ratio and total stored copies.
- Add known access and egress charges before comparing current and forecast run rate.
Calculator guide
Understanding Cloud Object Storage Cost Calculator
Object-storage cost is driven by retained data after compression and replication, then modified by access, retrieval, transaction, and egress charges.
Calculation method
How the calculation works
Translate daily cloud object storage creation into retained raw volume, apply compression and replica count, project monthly growth, and reconcile current and forecast storage capacity and run-rate cost. Daily raw volume times retention days gives retained raw data; divide by compression and multiply by copies; compound daily volume to the forecast month.

The visual separates daily ingest, retained raw volume, compressed copies, and forecast monthly cost.
Worked situations
Practical examples
- Two replicas double stored bytes after compression.
- A 4% monthly ingest increase compounds across the forecast horizon.
- Lifecycle tiering can reduce cost without reducing logical retained volume.
Better inputs
Useful tips
- Separate standard, infrequent-access, archive, and deep-archive pricing.
- Include request, retrieval, early-deletion, and egress fees where material.
- Reconcile billing units such as GB versus GiB.
Before relying on the result
Limitations and common mistakes
- The simplified price uses one storage rate.
- Lifecycle transitions, minimum object size, request counts, and regional pricing are not modeled separately.
- Vendor prices and retention policies can change.
Reference
Key terms
- Retained raw data
- Daily ingest multiplied by retention days before compression.
- Replica count
- Modeled stored copies represented in billable capacity.
- Run rate
- Forecast monthly storage plus entered access and egress cost.
Important note
Calculated from the entered technical values using the displayed model. Validate topology, workloads, capacity, security, redundancy, and observed performance before implementation.
Frequently asked questions
Does compression ratio include deduplication?
Use the combined observed reduction only if both are reflected in stored bytes.
Are replicas always separately billed?
It depends on the service and storage class; enter the billable copy basis.
Does the result include API requests?
Only if their estimated monthly cost is included in access and egress.
