Log Ingestion 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
- Monthly total cost = daily ingest GB x 30.4375 x ingest price per GB + retained TB x storage price per TB-month.
Test cases
Default input regression check
Generated from the checked-in default inputs and calculate function.
Inputs
- Log Sources: 120
- Events per Source per Day: 18,000
- Average Event Size: 900 bytes
- Index / Metadata Overhead: 20%
- Retention Period: 365 days
- Storage Multiplier: 1.2 x
- Ingest Price: 0.25 $/GB
- Retention Storage Price: 18 $/TB-mo
Expected outputs
- Monthly Total Cost: $33.26
- Daily Ingest: 2.17 GB
- Retained Storage: 0.93 TB
- Annual Total Cost: $399.11
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
- The calculators use transparent formulas rather than vendor-specific sizing or compliance models.
- Inputs are processed locally in the browser and are not stored by Calwarden.
- Log retention and audit coverage can be compliance-sensitive; confirm requirements before changing collection or retention policy.
Unit handling
- Log Sources accepts numeric values.
- Events per Source per Day accepts numeric values.
- Average Event Size accepts values in bytes.
- Index / Metadata Overhead accepts values in %.
- Retention Period accepts values in days.
- Storage Multiplier accepts values in x.
- Ingest Price accepts values in $/GB.
- Retention Storage Price accepts values in $/TB-mo.
- Monthly Total Cost is displayed as currency.
- Daily Ingest is displayed in GB.
- Retained Storage is displayed in TB.
- Annual Total Cost is displayed as currency.
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.
