Datadog DBM pricing in 2026: a real-world calculator (and what teams actually pay)

Datadog DBM list price says $35/DB-instance. The bill you get says $9,400/month. We break down host + DB-instance + APM + Infra + retention overages so you can model your actual number — and compare it line-by-line.

Every demo we run starts with the same conversation. The prospect tells us they pay Datadog DBM somewhere between $4k and $40k a month, and the next sentence is some variant of “but I can’t actually explain how we got there.” Datadog’s per-instance number on the pricing page is $35. The bill that lands in your inbox is doing something else.

This post breaks down the six line items, builds a real calculator for three fleet sizes, and gives you the number to take to procurement.

The headline number is one of six

Datadog’s DBM page lists $35 / database instance / month, annually billed. That’s real. It also covers approximately 25% of what the bill ends up being. The rest is in five other places.

The six line items

#Line itemList price (annual)Why it shows up
1DBM per DB-instance$35 / instance / moThe published DBM number. Per database, not per host.
2Infrastructure (Pro)$15 / host / moRequired. The agent that ships DBM data is the Datadog Agent.
3APM$31 / host / moRequired for the trace-to-query linking that makes DBM useful.
4Log retention$1.27 / mil log events ingested + $1.06 / GB / mo retentionDBM emits query events into Logs. Even on the ‘DBM only’ plan they show up.
5Custom metrics$0.05 / metric / mo over 100DBM creates per-query-digest metrics. A busy fleet trips this on day one.
6Long-term retention overageTieredDefault DBM retention is 15 months for queries / 1 hour for live activity. Extending it bills separately.

Calculator: three fleet sizes

We’ll model three configurations every Series A–C team we’ve talked to falls into. Per Datadog’s public list price, annually committed. All numbers per month.

Three line items teams forget

  • Custom metrics from DBM digests. Every distinct query digest becomes a metric. The 100-metric free tier vanishes the moment you have real traffic.
  • Log events from DBM samples. Slow-query samples land in Logs. The ingest + retention bill shows up under Logs, not DBM, which is how it slips past the DBM-cost review.
  • Required APM + Infra.You cannot buy DBM standalone. The Datadog Agent is APM’s agent, and the per-host APM and Infra modules are mandatory.

What the same fleet costs on Obsfly

FleetDatadog DBM (real)Obsfly (Team $39/DB)Annual savings
Small (20 DBs)$1,308 / mo$780 / mo~$6,300 / yr
Mid (50 DBs)$3,680 / mo$1,950 / mo~$20,800 / yr
Growth (200 DBs)$15,450 / mo$7,800 / mo~$91,800 / yr

Obsfly is one line item: $39 / DB / mo on Team, $89 on Business. No required APM. No per-host Infra. No log-event meter on slow queries. Same coverage of Postgres, MySQL, Mongo, Redis, ClickHouse, Oracle, SQL Server, Cassandra, Elasticsearch — plus BYOC.

How to actually negotiate

  • Ask for the “DBM-effective per-instance rate” including Infra + APM. Make them write it down. That’s your apples-to-apples comparator.
  • Demand a custom-metrics cap commitment. DBM’s per-digest metric explosion is the single biggest reason renewals balloon.
  • If you’re in regulated industries, get the BYOC quote from us. Datadog doesn’t sell it. Walking in with that quote tends to compress Datadog’s negotiation by 20–30%.

FAQ

Does the $35 DBM price include the agent host?+
No. The Datadog Agent is billed under Infrastructure ($15/host/mo Pro) and APM ($31/host/mo). Both are required.
Can I buy DBM without APM?+
Not in practice. The DBM SKU technically exists standalone but loses its core value (trace-to-query linking) without APM. Datadog AEs route every serious DBM deal through the APM + Infra bundle.
What's the actual per-DB number Obsfly customers pay?+
$39 / DB / month on Team, $89 on Business. No hosts, no APM dependency, no per-metric meter. BYOC adds a $5k/mo platform fee and drops the per-DB to $59.
How accurate is this calculator?+
These are public list prices applied to real fleet shapes from our pilot conversations. Your numbers will differ by ±20% based on log volume, custom-metric explosion, and negotiated discounts. The structural cost shape — five line items stacked on the headline — is the same for everyone.
