How Much Does a SaaS Cost at 10,000 Users?
What changes when a SaaS grows to roughly 10,000 users and which infrastructure costs deserve attention.
The important part
At 10,000 users, usage patterns start to matter substantially. A quiet B2B SaaS can cost far less than a consumer product with heavy requests, media and realtime activity.
Cost categories
| Category | Typical behavior | Main driver |
|---|---|---|
| Hosting | Moderate | Requests, compute and bandwidth |
| Database | Moderate | Connections, storage, backups and workload |
| Moderate | Notifications and lifecycle messaging | |
| Observability | Moderate | Logs, traces and retention |
| AI | Potentially large | Inference can dominate the bill |
What changes the bill?
- Concurrent traffic rather than registered users
- Database workload and connection patterns
- Bandwidth and file delivery
- Log/observability retention
- Inference volume and model mix
