Embedding Vector Storage Calculator
Raw embedding storage equals vector count multiplied by dimensions and bytes per component. One thousand 1,536-dimensional vectors at four bytes per component require 6,144,000 bytes before indexing overhead.
Formula & method
Raw bytes = vectors × dimensions × bytes per component; MiB = bytes ÷ 1,048,576.Worked example
| Input | Value |
|---|---|
| Number of vectors | 1,000 |
| Dimensions per vector | 1,536 |
| Bytes per component | 4 B |
| Result | Value |
|---|---|
| Raw vector payload | 6,144,000 B |
| Raw vector payload | 5.859375 MiB |
Compare scenarios
The first input changes while the other example inputs stay fixed. These are arithmetic scenarios, not forecasts.

| Example | 1,000 | 6,144,000 B | 5.859375 MiB |
| +20% | 1,200 | 7,372,800 B | 7.03125 MiB |
Assumptions & limits
This is a payload estimate, not a vector-database capacity quote. Index structures, metadata, IDs, alignment, replicas, backups and serialization can add substantial space. Four bytes is an illustrative representation size, not a requirement for every embedding format.
Displayed results are rounded. Calculations use unrounded JavaScript numbers; small floating-point differences are possible.

Convert a decimal GB amount into bytes and decimal or binary storage units. One GB is 1,000,000,000 bytes; one GiB is 1,073,741,824 bytes.
AI Token Cost Calculator
Token cost equals input tokens × input rate ÷ one million plus output tokens × output rate ÷ one million. Enter the rates for your actual provider and processing tier.
Request Transfer Volume Calculator
Estimated transfer bytes equal request count multiplied by average response size. Two million responses averaging 20 decimal KB contain 40 GB of payload.
Cached Input Cost Calculator
Mixed input cost equals cached tokens at the cache-read rate plus remaining tokens at the uncached rate. A cache hit fraction is an input assumption, not a guaranteed provider behavior.
