Vector Database Cost Calculator accuracy and testing

Formula source

• Bytes per vector = Dimensions x Bytes per dimension + Metadata bytes. Total storage GB = Vectors x Bytes per vector / 1024^3. Storage cost = Storage GB x monthly price per GB. Query cost = Monthly queries / 1,000 x price per 1,000 queries.

Test cases

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

• Pricing is user-entered because provider plans and free tiers change.
• The estimate does not include replicas, indexing overhead, backups, or minimum plan fees unless you include them in your rates.
• Storage uses binary GiB conversion with 1024^3 bytes per GB.

Unit handling

• Vector DB Pricing Preset accepts one of the configured options.
• Vectors accepts numeric values.
• Embedding Dimensions accepts numeric values.
• Bytes per Dimension accepts numeric values.
• Metadata per Vector accepts values in bytes.
• Storage Price accepts values in $/GB-mo.
• Monthly Queries accepts numeric values.
• Price per 1,000 Queries accepts values in $.
• Total Monthly Cost is displayed as currency.
• Estimated Storage is displayed in GB.
• Storage Cost is displayed as currency.
• Query Cost is displayed as currency.

Rounding rules
