How Much Does App Maintenance Cost Per Year?
Launch is not the finish line; it is the point where the meter starts. Founders who budget only for the build get surprised in month four. Here is what maintenance really costs and what it buys.

The 15–25% rule
Across the products we run for clients, annual maintenance lands between 15% and 25% of the original build cost. A $40k MVP costs roughly $6k–$10k a year to keep healthy — before any new features.
The low end applies to simple apps on managed infrastructure with few integrations. The high end applies to apps with payments, many third-party APIs, mobile apps on both stores, or AI features whose models and prompts need re-evaluation.
What the money buys
| Item | What it covers | Share |
|---|---|---|
| Hosting & services | Servers, database, email, storage, monitoring | 20–35% |
| Dependency & OS updates | Framework upgrades, iOS/Android releases, store policy changes | 20–30% |
| Bug fixes & support | Issues found by real users, small tweaks | 20–30% |
| Security | Patches, audits, certificate and key rotation | 10–15% |
| AI upkeep | Model version changes, eval re-runs, prompt tuning | 0–20% |
How to keep it at the low end
- Choose boring, popular technology. Obscure frameworks cost more to upgrade and to hire for.
- Use managed services for databases, auth and email instead of self-hosting.
- Ship with automated tests and CI from day one — they make every future update cheaper.
- Keep integrations behind a thin adapter layer so a vendor change touches one file.
- For AI features, keep an eval suite so model upgrades are a test run, not a gamble.
Retainer or pay-as-you-go?
A monthly retainer buys guaranteed response times and a team that already knows your code. Pay-as-you-go is cheaper for quiet apps but slower when something breaks. Most of our clients start with a small retainer in the first six months after launch — when most issues surface — and scale it down once the product settles.
Frequently asked questions
Can I skip maintenance for a year?
You can, but deferred updates compound. Skipping a year of framework and OS updates often turns a routine upgrade into a mini-rebuild.
Is maintenance included in your build price?
Every build includes a warranty period for defects. Ongoing maintenance is a separate, optional retainer.
Do app store updates really force work?
Yes. Apple and Google raise minimum SDK and privacy requirements regularly; apps that fall behind can be blocked from updating.
