Cloud PACS Storage Cost Calculator accuracy and testing
This page documents how Calwarden builds trust for this calculator: source notes, regression-style default tests, limitations, assumptions, unit handling, rounding, and visible change history.
Formula source
- Total monthly cost = storage TB * redundancy multiplier * storage price + retrieval GB * retrieval price + egress GB * egress price + platform fee.
Test cases
Default input regression check
Generated from the checked-in default inputs and calculate function.
Inputs
- Storage Vendor Preset: pacs_vendor_archive_planning
- Stored Archive Size: 250 TB
- Storage Price: 18 $/TB-mo
- Redundancy Multiplier: 1.2 x
- Monthly Retrieval: 2,500 GB
- Retrieval Price: 0.01 $/GB
- Monthly Egress: 1,000 GB
- Egress Price: 0.05 $/GB
- Monthly Platform Fee: $750
Expected outputs
- Total Monthly Cost: $6,225.00
- Storage Cost: $5,400.00
- Retrieval Cost: $25.00
- Egress Cost: $50.00
- Billable Storage: 300 TB
Known limitations
- This page documents the checked-in calculator logic and does not certify results for every real-world edge case.
- Use the result as a planning estimate unless the calculator page states a stricter purpose.
Assumptions
- All prices are user-entered because provider and PACS vendor pricing changes.
- The estimate does not include taxes, implementation, migration labor, network circuits, or support terms unless entered as a platform fee.
- Results are for budget planning only and are calculated locally.
Unit handling
- Storage Vendor Preset accepts one of the configured options.
- Stored Archive Size accepts values in TB.
- Storage Price accepts values in $/TB-mo.
- Redundancy Multiplier accepts values in x.
- Monthly Retrieval accepts values in GB.
- Retrieval Price accepts values in $/GB.
- Monthly Egress accepts values in GB.
- Egress Price accepts values in $/GB.
- Monthly Platform Fee accepts values in $.
- Total Monthly Cost is displayed as currency.
- Storage Cost is displayed as currency.
- Retrieval Cost is displayed as currency.
- Egress Cost is displayed as currency.
- Billable Storage is displayed in TB.
Rounding rules
- Number displays use up to 2 decimal places in the calculator UI.
- Currency outputs are displayed with standard US dollar formatting.
- Input precision follows configured step values where provided.
