Next.js + Supabase Cost: What Should You Budget?
Understand the cost drivers of a Next.js and Supabase stack without relying on a single misleading monthly number.
The important part
Next.js and Supabase can be a cost-efficient starting combination, but the actual bill depends on hosting, database usage, storage, bandwidth and the paid tiers required by your workload.
Cost categories
| Category | Typical behavior | Main driver |
|---|---|---|
| Web hosting | Traffic dependent | Builds, bandwidth and compute |
| Database | Usage dependent | Database size, compute and backups |
| Auth | Usage dependent | Users and authentication volume |
| Storage | Usage dependent | Stored files and transfer |
| Separate provider | Transactional email is often separate |
What changes the bill?
- Active users and database workload
- File storage and transfer
- Build frequency and server execution
- Email volume
- Whether free tiers remain appropriate
