Summary: Estimated monthly embedding spend is $4.00.
Summary: 10,000 documents × 8 chunks × 500 tokens estimates 40,000,000 tokens per run.
⚠️ Uses a constant average token count and rate. Retries, provider minimums, dimensions, storage, and vector database charges are excluded.

Formula & Mathematical Methodology: Embedding API Cost Calculator

Tokens/Run = Documents × Chunks/Document × Tokens/Chunk
Cost = Tokens × Rate ÷ 1,000,000 × Re-index Runs
Tokens/Run = Documents × Chunks/Document × Tokens/Chunk; Cost = Tokens × Rate ÷ 1,000,000 × Re-index Runs
  • : Documents
  • : Chunks per document
  • : Average tokens per chunk
  • : Embedding rate per million tokens

Rounding: Displayed values are rounded for readability; calculations retain full floating-point precision.

Worked Example: 10,000 documents, 8 chunks each, 500 tokens per chunk

Estimate one full indexing run using an entered $0.10 per million token rate.

  1. Estimate tokens in each document chunk.
  2. Multiply by document and chunk counts.
  3. Apply the embedding rate and re-index frequency.
Result: The initial run contains about 40 million tokens; monthly spend scales with re-index frequency.

Frequently Asked Questions

Does this include vector storage?

No. It estimates embedding API usage only. Storage and retrieval costs need separate inputs.

How to Use the Embedding API Cost Calculator: Practical Guide & Visual Analysis

Estimate API costs for initial indexing and scheduled re-indexing using the selected embedding model’s rate. Whether you are researching embedding token cost calculator, vector embedding api cost, document embedding cost, embedding pricing calculator, this interactive tool helps you estimate the token volume and API cost of embedding documents or chunks for a search system.

Interpreting the 3 Custom Visual Graphs & Key Outputs

As you adjust Display Currency, Documents, Chunks per Document, Tokens per Chunk, the calculator immediately computes Primary result, Supporting calculation metrics, Three calculator-specific visualizations and updates all three domain-specific SVG charts in real time. Instead of relying on a single static figure, you can inspect the primary domain diagram, component breakdown, and multi-point trajectory curve to see how changing your inputs shifts the final result. Use the Compare (up to 3 scenarios) button to evaluate side-by-side variations before making a decision.

Real-World Benchmark & Planning Tips (Global; user-entered values, assumptions and currency)

In our benchmark scenario (10,000 documents, 8 chunks each, 500 tokens per chunk), The initial run contains about 40 million tokens; monthly spend scales with re-index frequency. Keep in mind that document and chunk averages remain stable; all tokens are billed at one rate.
