Embedding Storage 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

  • Vectors = documents * chunks per document. Raw storage GB = vectors * (dimensions * bytes per dimension + metadata bytes) / 1024^3. Billable GB = raw GB * (1 + overhead percent / 100) * replicas.

Test cases

Default input regression check

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

Inputs

  • Documents: 50,000
  • Chunks per Document: 4
  • Embedding Dimensions: 1,536
  • Bytes per Dimension: 4
  • Metadata per Chunk: 768 bytes
  • Index Overhead: 35%
  • Replicas: 1
  • Storage Price: 0.25 $/GB-mo

Expected outputs

  • Billable Storage: 1.74 GB
  • Vectors: 200,000
  • Raw Storage: 1.29 GB
  • Monthly Storage Cost: $0.43

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

  • Uses 1024^3 bytes per GB.
  • Pricing and overhead are user-entered.
  • No document or embedding data is uploaded.

Unit handling

  • Documents accepts numeric values.
  • Chunks per Document accepts numeric values.
  • Embedding Dimensions accepts numeric values.
  • Bytes per Dimension accepts numeric values.
  • Metadata per Chunk accepts values in bytes.
  • Index Overhead accepts values in %.
  • Replicas accepts numeric values.
  • Storage Price accepts values in $/GB-mo.
  • Billable Storage is displayed in GB.
  • Raw Storage is displayed in GB.
  • Monthly Storage 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.
