How Much Does a SaaS Cost at 1,000 Users?
A practical framework for estimating monthly infrastructure costs for a SaaS with around 1,000 users.
The important part
There is no single infrastructure bill for 1,000 users. Activity, database size, bandwidth, email volume, observability and AI usage matter more than the raw user count.
Cost categories
| Category | Typical behavior | Main driver |
|---|---|---|
| Hosting | Low to moderate | Web traffic and compute |
| Database | Low to moderate | Queries, storage and backups |
| Low to moderate | Transactional volume | |
| Storage/CDN | Variable | Media and downloads |
| AI | Optional / highly variable | Tokens and model choice |
What changes the bill?
- Monthly active users and requests per user
- Database size and query complexity
- File/media bandwidth
- AI requests and token volume
- Third-party paid plans
