Next.js + Firebase Cost: What Should You Budget?
Understand the cost drivers when combining Next.js with Firebase services.
The important part
Firebase pricing is usage-driven across several products. Model reads, writes, storage, bandwidth and authentication rather than assuming a flat application price.
Cost categories
| Category | Typical behavior | Main driver |
|---|---|---|
| Web hosting | Variable | Hosting/bandwidth depending on setup |
| Firestore | Usage dependent | Reads, writes, storage and indexes |
| Auth | Usage dependent | Provider and authentication method |
| Storage | Usage dependent | Stored objects and downloads |
| Functions | Usage dependent | Invocations and compute |
What changes the bill?
- Firestore read/write volume
- Bandwidth and downloads
- Function invocations
- Authentication volume
- Storage and indexing
