How this calculator works
Enter number of vectors, dimensions per vector, bytes per component, index and metadata overhead (%). Select Calculate to apply the displayed formula and review the labeled results.
Formula / method
Storage = vectors × dimensions × bytes per component × (1 + overhead ÷ 100)
Worked example
One million 1,536-dimensional float32 vectors use 6.144 GB raw and about 7.99 GB with 30% overhead.
Assumptions and limitations
All vectors have equal dimensions and use the selected fixed-width representation.
Vector databases vary widely in index structure, compression, replicas, metadata, alignment and temporary build space.
