Datadog Pricing in 2026: A Complete Guide to Plans, Costs, and Optimization
Datadog uses per-product, per-host pricing rather than a single platform fee. Infrastructure monitoring starts at $15/host/month on an annual commitment ($18 on-demand), while APM costs $31/host/month and requires a paired Infrastructure plan. Logs are billed separately at $0.10 per ingested GB plus $1.70 per million indexed events, making ingestion and indexing the biggest cost drivers. The main pricing pitfalls are excess custom metrics, higher-cost on-demand usage, and enabling more products than necessary. For steady, predictable workloads, annual commitments typically save 20–50% compared to on-demand pricing, but it’s best to commit only to your baseline usage rather than peak demand.
Datadog is one of the most powerful observability platforms out there, but its billing can catch teams off guard. Unlike traditional software with a single plan price, Datadog charges per product, per host, and per GB, meaning the moment you enable Infrastructure, APM, and Logs together, costs start stacking up fast. This breakdown covers exactly how Datadog pricing works in 2026, what the real per-host cost looks like beyond the $15 headline, and the three traps-custom metrics, on-demand usage, and product sprawl, that quietly inflate most bills.
How Much Does Datadog Cost in 2026?
Datadog pricing is a per-product model billed mostly per host per month, with logs billed per GB and per indexed event. There is no single plan price — the total is the sum of every module you turn on (Infrastructure, APM, Logs, RUM, Synthetics, and more), billed either annually or at a higher on-demand rate.
Here are the headline list prices for the products that drive most bills, as published on Datadog's pricing page:
| Product | Tier | Annual Price | On-Demand |
|---|---|---|---|
| Infrastructure | Pro | $15 / host / month | $18 |
| Infrastructure | Enterprise | $23 / host / month | $27 |
| APM | Standard | $31 / host / month | $48 |
| APM | Enterprise | $40 / host / month | $60 |
| Logs – Ingestion | — | $0.10 / GB | $0.10 |
| Logs – Indexing (15-day) | — | $1.70 / million events | $2.55 |
STAT: On-demand Datadog usage costs roughly 20 to 50 percent more than the same product billed annually ,APM jumps from $31 to $48 per host, and log indexing from $1.70 to $2.55 per million events.
How Does Datadog Per-Host Pricing Work?
A "host" is any physical or virtual machine, or equivalent compute instance, running the Datadog agent. Infrastructure and APM both bill per host per month. Two details catch teams out:
- Hosts are counted hourly, billed on a high-water mark. Datadog bills the 99th-percentile host count over the month, so a few hours of autoscaling spikes can raise the whole month's bill.
- Annual commitments lock a host floor. You commit to some hosts at the annual rate; usage above that floor bills at the higher on-demand rate. Commit to your baseline, not your peak.
STAT: Datadog bills infrastructure hosts on the 99th-percentile (high-water-mark) count for the month, not the average, so transient autoscaling can inflate the bill well beyond steady-state host count.
How Much Does Datadog APM Cost?
Datadog APM is $31 per host per month, billed annually (APM Pro $35, APM Enterprise $40), or $48 per host on-demand. The structural catch: APM cannot be purchased standalone; every APM host needs a paired Infrastructure plan, so the real per-host cost of adding tracing is Infrastructure plus APM, or roughly $46 per host per month at the Pro and Standard tiers.
Each APM host includes 150 GB of ingested spans and 1 million indexed spans per month at 15-day retention. Span volume above that allotment bills separately, which is where APM bills quietly grow on high-throughput services.
How Much Does Datadog Log Management Cost?
Logs are the most misunderstood line on the Datadog bill because ingestion and indexing are billed separately:
| Log Cost | What It Covers | Price |
|---|---|---|
| Ingestion | Every GB collected or scanned | $0.10 / GB |
| Standard Indexing | Events made searchable (15-day retention) | $1.70 / million events |
| Flex Storage | Long-retention, lower-cost storage | $0.05 / million events |
The lever is decoupling the two. You can ingest everything for $0.10 per GB to keep it available for search and archiving, then index only the events you actually query. Moving high-volume, low-value logs to the Flex tier instead of standard indexing is one of the largest single savings in any Datadog account.
STAT: Standard log indexing costs $1.70 per million events while Flex Storage costs $0.05 per million, a 34x difference that makes indexing-tier choice the biggest single lever in Datadog log cost.
Why Are Datadog Bills So High?
The $15-per-host headline is real, but few teams pay anything close to it. Three traps drive the gap:
- Custom metrics overage. Pro includes 100 custom metrics per host, Enterprise 200. Past that, custom metrics bill individually, and a single misconfigured high-cardinality tag can generate thousands of custom metrics overnight.
- On-demand usage. Anything above your annual commitment bills at the on-demand rate, 20 to 50 percent higher. Under-committing to "stay flexible" quietly costs more.
- Product sprawl. Infrastructure plus APM plus Logs plus RUM plus Synthetics stacks into a per-host figure several times the headline rate before anyone notices.
How Do You Reduce Datadog Costs?
Six levers, in rough order of payback:
- Cap and audit custom metrics. Find high-cardinality tags and drop the metrics nobody queries. Usually the fastest large win.
- Tier your logs. Index only what you search; move the rest to Flex or archive. See the 34x indexing gap above.
- Right-size APM retention and sampling on high-throughput services.
- Downgrade dev and staging hosts to a lower tier or turn off products they do not need.
- Commit annually to your baseline host count, keep bursts on-demand.
- Give the bill an owner. Track Datadog spend alongside cloud cost so it is allocated, not orphaned.
Conclusion
Datadog's pricing isn't complicated once you know the structure, but it rewards teams that actively manage it and quietly punishes those that don't. Capping custom metrics, tiering your logs, committing annually to your baseline, and giving the bill a clear owner are the moves that separate a predictable Datadog spend from one that surprises you every invoice. The $15-per-host headline is real, it's just rarely the number that shows up at the end of the month.
FAQs
Datadog is billed per product. Infrastructure starts at $15 per host per month (Pro, annual) or $18 on-demand; Enterprise is $23. APM adds $31 per host, log ingestion is $0.10 per GB, and indexing is $1.70 per million events. A typical infrastructure + APM + logs host runs $40 to $70+ per month before custom metrics.
Per-product, mostly per-host pricing billed annually (cheaper) or on-demand (20 to 50 percent more). Infrastructure and APM bill per host; logs bill per ingested GB plus per million indexed events; custom metrics bill beyond a per-host allotment. The total is the sum of every product you enable.
$31 per host per month billed annually (APM Pro $35, Enterprise $40), or $48 on-demand. APM requires a paired Infrastructure plan, so the real cost of adding tracing is roughly $46 per host. Each APM host includes 150 GB of spans and 1 million indexed spans at 15-day retention.
Ingestion is $0.10 per GB. Standard indexing is $1.70 per million events at 15-day retention ($2.55 on-demand). Flex Storage is $0.05 per million events stored. Ingestion and indexing are billed separately, so index only what you query.
Custom metrics past the per-host allotment, on-demand usage priced 20 to 50 percent above annual, and product sprawl across Infrastructure, APM, Logs, RUM, and Synthetics. The $15 headline is the floor, not the typical per-host cost.
Cap custom metrics, tier logs to Flex, right-size APM retention, downgrade non-production hosts, commit annually to your baseline, and allocate Datadog spend to the teams driving it in a unified FinOps platform.
