How this estimate is built

Storage size is computed as vector count times dimensions times 4 bytes (float32 precision), converted to gigabytes and multiplied by the provider's per-GB monthly storage rate. Query cost is your monthly query volume divided by one million and multiplied by the provider's per-million read-unit rate.

It doesn't account for metadata storage overhead, index type (HNSW vs IVF), replication factor, write-unit costs (Pinecone charges ~$2/1M write units separately), or free-tier allowances. Qdrant Cloud actually bills by node-hour rather than per-GB — the rate shown here is a GB-equivalent approximation for comparison, not Qdrant's real invoice line item. Real-world vector database bills commonly run 2.5-4x higher than the sticker estimate once reranking, backups, and data transfer are added — treat this as a floor, not a ceiling.

Frequently asked questions

How is vector database cost calculated?

Storage cost is based on vector count times dimensions times 4 bytes (float32), converted to GB and multiplied by the provider's per-GB monthly rate. Query cost is your monthly query volume multiplied by the provider's per-read-unit rate.

Why do dimensions matter so much for cost?

Each dimension adds 4 bytes per vector at float32 precision, so a 1536-dimension embedding model stores 6x more data per vector than a 256-dimension model, directly multiplying your storage bill.

Can I reduce vector database costs without losing accuracy?

Yes. Techniques like quantization (int8 or binary), dimensionality reduction, and deleting stale vectors can cut storage cost significantly, often with a small and testable accuracy tradeoff.
