Vector DB Cost - Pinecone vs Weaviate vs Qdrant vs pgvector

🚀 Open the calculator

Meet Vihaan Reddy. Backend Engineer choosing vector storage. "Pinecone is easiest. pgvector is cheapest. What does each actually cost at 5M vectors?"

🔥 Boss wants the cheapest option. Eng team wants Pinecone.

The story

Vector DB pricing has the biggest spread of any RAG component. Same workload (5M vectors, 1M queries/month) costs $1,400/mo on Pinecone Enterprise, $200/mo self-hosted Qdrant on a single VM, $50/mo pgvector on existing Postgres. The 28× spread between Pinecone hosted and pgvector is real - and the 'right' choice depends on operational maturity, not just unit cost.

Vihaan's choice: 5M vectors, ~1M queries/month, expecting 30% growth/year. Pinecone Serverless ($800/mo) is operationally trivial. Self-hosted Qdrant ($200/mo) saves real money but needs SRE attention. pgvector on existing Postgres ($50/mo extra) is cheapest - but locks performance to your Postgres setup and limits scale.

Three real choices, not nine. (1) Hosted SaaS (Pinecone, Weaviate Cloud) for fast-ship + ops-free. (2) Self-hosted dedicated (Qdrant, Milvus, Weaviate self-hosted) for cost-conscious + ops-capable. (3) pgvector for small-scale + Postgres-native. Don't overthink the 9 vendors - the architectural pattern matters more than the brand.

Vector DB Cost - Pinecone vs Weaviate vs Qdrant vs pgvector full size

🎛 Inputs you control

Each input shapes the cost. Click an input on the calculator to set it — explanations below match the live calculator field by field.

▸ Total vectors — Total vectors (chunks/embeddings) stored in the index.
How to choose: Docs times chunks per doc; e.g. 10K docs x 3 chunks = 30K vectors.
▸ Vector dimensions — Embedding dimensionality, which drives storage and RAM.
How to choose: Match your embedding model: 1024 Cohere/Voyage, 1536 OpenAI 3-small, 3072 3-large.
▸ Queries per second (peak) — Peak queries per second the index must serve.
How to choose: Use peak, not average; 5 QPS is about 13M queries per month.
▸ Vector writes per month — New vectors added per month via incremental indexing.
How to choose: Estimate ongoing ingestion; large spikes push managed-tier pricing up.
▸ Deployment preference — Filter results to managed, self-hosted, or all options.
How to choose: Managed means no ops; self-hosted is lowest dollar cost if you have the team.

About this calculator: Vector DB Cost - Pinecone vs Weaviate vs Qdrant vs pgvector

Vector DB pricing varies 10× between hosted SaaS and self-hosted. Storage cost + query cost + ops overhead. Real math for RAG production.

Reading your result

Pinecone Serverless ≈ $0.80-1.20/M queries + $0.30/GB-month storage. 5M vectors at 1536 dims = ~30GB = $9 storage. 1M queries = $1. Plus baseline = $40 minimum. Total ~$50-100/mo at this scale.

Self-hosted Qdrant ≈ $150-300/mo on a $200 VM. Add maintenance overhead (SRE time). Operationally meaningful at scale.

pgvector ≈ marginal cost on existing Postgres. Adds ~30GB to Postgres + a few CPU cycles per query. Often $20-100/mo extra on existing setup. Best for <10M vectors and simple use cases.

Weaviate Cloud is similar to Pinecone - premium hosted, slightly different pricing model (per-pod vs per-query). Comparable total at this scale.

What "good" looks like:
  • Hosted SaaS: $50-2K/mo at 5M vectors. Fast ship, ops-free, expensive at scale.
  • Self-hosted dedicated: $100-400/mo. SRE time required.
  • pgvector: $20-100/mo. Best for <10M, simple cases.
  • Switching cost: 2-4 weeks engineering, painful at scale.

$41.10 / month ≈ $493.18 / year

500K vectors, low query volume. Pinecone Serverless ~$25/mo. Setup: 1 hour. Don't optimize for cost yet - ship the feature.

Healthy range: <$30/mo - Pinecone wins on speed

Trade-offs

Cost isn't the only dimension. Click any constraint — see how recommendations change.

What matters most to you? Click any dimension — recommendations update.

Best fit for "cost":

  1. pgvector Cheapest for <10M vectors
  2. Qdrant self-hosted Cheapest for >10M vectors
  3. Pinecone Serverless Cheapest hosted

Cost ranking depends on scale. <10M vectors: pgvector wins. 10M-1B: Qdrant or Milvus self-hosted. Hosted SaaS only justifiable for fast-ship or sub-10M with no Postgres.

What this calculator can't tell you

Honest limitations — every model is wrong; some are useful. Where this one falls short:

For these, use: Embedding Cost for upstream. RAG Pipeline for downstream.

Where to go next

Cost the embedding side →

Indexing + query embedding costs.

 Full RAG architecture cost →

Embedding + vector DB + retrieval + LLM.

Same logic applies to vector DB self-host vs SaaS.

3 years of pricing history

Why this matters: pricing for major vendors has dropped 40-90% in the last 24 months. A budget set 12 months ago is probably wrong by 30%+.
