Compression Ratio Savings 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

  • Compressed storage = original storage / compression ratio. Saved storage = original - compressed. Monthly savings = saved storage * redundancy multiplier * storage price.

Test cases

Default input regression check

Generated from the checked-in default inputs and calculate function.

Inputs

  • Original Storage: 100 TB
  • Compression Ratio: 2 :1
  • Redundancy Multiplier: 1.2 x
  • Storage Price: 18 $/TB-mo

Expected outputs

  • Monthly Savings: $1,080.00
  • Compressed Storage: 50 TB
  • Storage Saved: 50 TB
  • Annual Savings: $12,960.00

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

  • Compression ratio is effective across the whole dataset.
  • Storage pricing is entered by the user.
  • No imaging data is processed.

Unit handling

  • Original Storage accepts values in TB.
  • Compression Ratio accepts values in :1.
  • Redundancy Multiplier accepts values in x.
  • Storage Price accepts values in $/TB-mo.
  • Monthly Savings is displayed as currency.
  • Compressed Storage is displayed in TB.
  • Storage Saved is displayed in TB.
  • Annual Savings 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.
