Object storage cost calculator
Work out the money first, then pick a provider: drag the ruler for storage, drag across the chart for monthly data traffic, and every provider’s monthly cost is drawn on the same axes.
Archive classes include their retrieval fee and minimum storage duration; uploads and traffic inside the same provider are usually free.
How to read the chart
Basis and sources
Prices were captured on 2026-10-05/06 from each provider’s official pricing page or price API. Every provider name in the Data and assumptions table links to its source.
That table lists each class’s unit price, retrieval fee, free allowance, minimum spend and the formula used. Anything that could not be confirmed from an official page is marked “Not confirmed” and stays off the chart.
Prices change, and a provider’s overseas regions may differ from its base region — always check the official page before you buy.
