Using your entered rate
Important: the default rate is illustrative. Check the provider’s official pricing page and add indexes, backups, query compute, ingestion, network, and minimums.
Formula
vectors = documents × chunks per document
vector bytes = vectors × dimensions × bytes per dimension × replicas
metadata bytes = vectors × metadata KB × 1,024 × replicas
monthly cost = total decimal GB × your rate
This is a transparent baseline. A production vector database can use more space for indexes, replicas, compaction, backups, and operational metadata.
