How much does it cost to maintain an app? As an industry rule of thumb, budget 15–25% of the original build cost per year for ongoing maintenance. So an app that cost $80,000 to build typically costs $12,000–$20,000 per year to keep running well. That number surprises a lot of business owners — but an app isn’t a one-time purchase. It’s more like a car: the purchase price is just the beginning.
This guide breaks down what app maintenance actually includes, why the costs exist, what happens if you skip maintenance, and how to budget for it realistically in 2026.
How Much Does It Cost to Maintain an App? The 15–25% Rule
The 15–25% figure is a widely cited industry rule of thumb, not a law of physics. Where you land in that range depends on complexity:
- ~15%/year: Simple apps with few integrations, stable requirements, and modest user bases. Mostly OS updates, minor fixes, and hosting.
- ~20%/year: Typical business apps — backend with a database, payment processing, a couple of third-party integrations, regular small improvements.
- ~25%/year: Complex apps with many integrations, real-time features, high security needs, or active feature development alongside maintenance.
To put it in dollars, using typical build costs:
- $40,000 MVP → roughly $6,000–$10,000/year to maintain
- $80,000 business app → roughly $12,000–$20,000/year to maintain
- $150,000+ complex app → roughly $22,000–$37,500+/year to maintain
Remember: these are typical ranges. Your actual cost depends on what’s in the app and how actively it’s developed after launch.
What App Maintenance Actually Includes
“Maintenance” sounds like doing nothing, but it’s active work. Here’s where the money goes:
1. OS and device compatibility
Apple and Google release major OS updates every year, and each one can break things — deprecated APIs, changed permissions, new screen sizes, new hardware. Someone has to test your app against every release and fix what breaks. Skip this and your app starts crashing on new phones within a year or two.
2. Bug fixes
No app launches bug-free. Real users find edge cases that testing missed. Ongoing maintenance includes a steady stream of small fixes — the unglamorous work that keeps ratings up.
3. Security updates
Libraries and frameworks get security patches constantly. An unmaintained app accumulates known vulnerabilities — a real liability if you handle user data or payments. This isn’t optional; it’s the cost of operating safely.
4. Backend, hosting, and third-party services
Servers, databases, push notification services, analytics, payment processor fees, SSL certificates, domain renewals — the infrastructure bill runs whether or not you touch the code. Third-party APIs also change: when Stripe or Google Maps updates their API, your integration needs updating too.
5. App store compliance
Apple and Google periodically change their requirements — privacy manifests, target SDK versions, permission disclosures. Fall behind and your app can be removed from the store until it’s updated.
6. Small improvements
The best-maintained apps also evolve: minor UX tweaks, copy changes, small features requested by users. This is technically “development,” but in practice it blends into maintenance.
What Happens If You Skip App Maintenance
We’ve seen what happens to unmaintained apps, and it’s never “nothing”:
- Year 1: Mostly fine. A few minor glitches on the newest OS version.
- Year 2: Noticeable problems — crashes on new devices, broken integrations as third-party APIs change, security warnings.
- Year 3: The app may not install or run on current phones at all. App Store removal becomes a real risk. At this point, “maintenance” often means an expensive rebuild.
The cruel math: skipping $15,000/year in maintenance for three years doesn’t save $45,000 — it often leads to a $60,000+ rebuild, plus the lost users and revenue in between. Maintenance is the cheaper option.
An app is not a product you finish. It’s a product you operate. Budget for it like one.
What You Can Handle Yourself vs What Needs a Developer
Not all maintenance requires paying a developer. Here’s a realistic split:
- You can do yourself: Updating app store listings and screenshots, responding to user reviews, basic content updates (if you have an admin panel), monitoring analytics, renewing domains and certificates on time.
- Needs a developer: OS compatibility updates, security patches, bug fixes, API integration updates, performance issues, anything involving code changes or server configuration.
This is why a care plan makes sense for most small businesses: the developer-side work is non-negotiable and ongoing, while the business-side work stays in your hands. Trying to skip the developer side to save money is exactly how apps end up broken and unusable within a couple of years.
How Much Does It Cost to Maintain an App After the First Year?
Maintenance costs aren’t flat. Year one tends to run highest — you’re fixing launch bugs, responding to initial user feedback, and making the first round of adjustments. Years two and three usually settle toward the lower end of the 15–25% range as the app stabilizes.
Expect periodic spikes: major iOS or Android releases, a payment provider changing their API, or a security issue in a core library can each trigger a focused round of work. A care plan smooths these spikes into a predictable monthly cost instead of surprise invoices — which is precisely why we recommend one.
How to Budget for App Maintenance
- Use the 15–25% rule when planning your build. If you can’t afford the maintenance, you can’t afford the app — scale the build down until the total cost of ownership works.
- Prefer a care plan over ad-hoc fixes. A fixed monthly plan (like ours below) is predictable and ensures small issues get handled before they become big ones. Paying hourly for emergency fixes is always more expensive.
- Keep a small improvement budget. Even 2–3 hours of development per month keeps the app evolving and users happy.
- Review integrations annually. Every third-party service is a dependency and a potential bill. Once a year, check you’re still using — and needing — all of them.
Our App Care Plans
This is exactly what our care plans are for. Our published app pricing includes ongoing care plans from $49–$149/month — covering updates, compatibility fixes, security patches, and small improvements, so the 15–25% rule doesn’t become a surprise line item. For smaller apps and MVPs, a care plan is almost always cheaper than paying for fixes ad hoc.
The honest pitch: we’d rather maintain your app for a predictable monthly fee than rebuild it in two years after neglect. Your users — and your budget — will thank you.
