How much does CosmosDB cost?

CosmosDB publishes 2 tiers, from Free for Free Tier up to Free for Serverless. The entry tier costs nothing.

Does CosmosDB have a free plan?

Yes. The Free Tier tier costs nothing and covers 1000 ru/s, 25gb storage, first 12 months.

What is the difference between Free Tier and Serverless on CosmosDB?

Serverless costs Free against Free, and adds pay per request, auto-scaling, event-driven workloads.

Does CosmosDB charge per user?

The record carries a price and a billing period for each of its 2 tiers, but not the unit that price is charged in. Per-seat and flat-rate billing look identical in this data, so check the vendor's page before budgeting for a team.

Are these CosmosDB prices current?

They are what the catalogue entry holds, refreshed when the entry is. Vendors change pricing without notice and nobody at Softwr re-verifies each tier by hand, so treat this as a structured summary and the vendor's own pricing page as the authority.

What should I compare CosmosDB against before paying?

Nothing else in this directory is filed close enough to CosmosDB to make a useful price comparison.

CosmosDB pricing

CosmosDB publishes 2 tiers. Below is each one, what it adds over the tier beneath it, and where the ladder stops being worth climbing for most people.

Entry price: Free
Model: Usage-based
Tiers: 2
Free tier: Yes

CosmosDB plans, side by side

Every published tier in ascending order of price, with the number of features each one lists. An absence here means the record does not itemise it, not that the tier lacks it.

Serverless	Free	3	+$0/month, 3 more features

What each tier adds

The set difference between each tier's feature list and the one beneath it. Where a tier lists nothing new, the vendor has either stopped repeating the inherited list or the tier raises limits rather than adding capability, the record does not distinguish the two, so this page does not either.

Azure support

People bring CosmosDB in for running a globally distributed multi model database on azure, serving low latency reads and writes from multiple azure regions, storing document, key value and graph data behind a managed service. If that is not the job you are buying for, the alternatives to CosmosDB are worth a look before you commit to a tier.

Before you pay for CosmosDB

Three things this page cannot tell you, and all three change the bill. The record carries a price and a billing period but not the unit - per-seat and flat-rate pricing are indistinguishable in this data, so a five-person team may be looking at five times the figure above. It carries no annual rate, so any discount for paying yearly is not something this page can quote. And it carries no trial length.

What it can tell you is the shape of the ladder: 2 tiers between Free and Free, with the jump itemised above. Because there is a free tier, the cheapest way to answer the rest is to use it before paying anything.

CosmosDB runs on web, azure, and is published by Microsoft Corporation of Redmond, Washington. The full record is on the CosmosDB review.
