How Much Does It Cost to Maintain an App in 2025?

From bug fixes to server bills, app maintenance isn’t optional—it’s a budget you can’t ignore.

Launching an app is exciting—but it’s only the start. The real challenge lies in keeping your app running smoothly, secure, and competitive in an ever-changing digital landscape. That’s where mobile app maintenance comes in. From regular app updates and bug fixes to server costs, security patches, and customer support, maintenance is a continuous investment that can’t be ignored.

In 2025, app maintenance costs can vary widely. Small apps may require as little as $5,000 per year, while complex, high-traffic platforms can exceed $100,000 annually. On average, businesses should budget 15%–20% of their initial development cost for yearly maintenance (source). Early-stage apps may even see costs rise to 40%–50% in the first year as developers address initial bugs and user feedback.

Understanding your app’s running cost is crucial for long-term success. This guide breaks down the different types of maintenance, key cost factors, and practical tips to optimize your mobile app maintenance budget in 2025. So you can plan effectively and avoid costly surprises.

What is App Maintenance?

App maintenance is the continuous process of keeping your application in optimal condition after its initial release. It is fundamentally different from one-time development. While development is about building the product from the ground up, maintenance is about nurturing and improving it over time.

Skipping regular updates is a major risk. Your app can quickly become outdated, riddled with bugs, and vulnerable to security threats. This leads to poor user reviews, a high rate of uninstalls, and, ultimately, a significant drop in your return on investment (ROI). In the competitive app market, a neglected app is a dying app.

Example: Snapchat experienced a drop in daily active users when certain features weren’t updated promptly, highlighting the importance of consistent maintenance. (source)

Types of App Maintenance Costs

Maintenance costs are a mix of monthly and yearly expenses. They are typically broken down into four key categories:

Corrective Maintenance

This involves fixing bugs, errors, and crashes that appear after launch. This is often a reactive process, but it’s crucial for user retention.

Adaptive Maintenance

This is all about keeping your app compatible with the ever-changing tech landscape. It includes updates for new operating systems (future iOS and Android versions), new devices, and third-party APIs.

Perfective Maintenance

This involves proactive work to improve the app. It includes adding new features, enhancing the user interface (UI) and user experience (UX), and optimizing performance to keep your app competitive.

Preventive Maintenance

This involves backend tasks that prevent future problems. It includes code refactoring, system monitoring, and optimizing server usage.

Here’s a breakdown of the common expenses

Server Costs & Hosting

Your app’s infrastructure needs to be hosted on servers. This can include cloud services like AWS, Google Cloud, or Azure. Costs depend on the amount of data stored, bandwidth usage, and the number of active users. They can range from $70 to $350 per month for a moderate app, but scale up significantly for enterprise-level platforms.

App Updates & Bug Fixes

This is a continuous process. Minor bug fixes might cost a few hundred dollars, while a major feature overhaul could run into thousands. You’ll need to budget for regular releases to fix issues and stay current.

Backend Maintenance & Database Management

The “brain” of your app needs constant care. This includes managing databases, ensuring data integrity, and optimizing backend performance for speed and reliability.

Security & Compliance Updates

With increasing cyber threats, security is non-negotiable. You’ll need to regularly apply security patches, conduct audits, and ensure compliance with regulations like GDPR or HIPAA, especially if your app handles sensitive user data. This can add $2,000 to $20,000 per year to your costs.

Customer Support & Monitoring

Providing user support and monitoring your app’s performance with tools like Firebase Crashlytics or AppDynamics are essential. This helps you identify issues proactively and respond to user feedback.

Key Factors Affecting App Maintenance Cost

The final cost of app maintenance isn’t a fixed number. It’s determined by several key factors:

App Complexity & Tech Stack: A simple app built with a standard tech stack is far cheaper to maintain than a complex platform with advanced features like AI, augmented reality, or real-time data processing. The more integrations, functionalities, and lines of code you have, the more effort (and money) it takes to maintain.

Frequency of OS Updates: Apple and Google release new OS versions annually, which often require developers to make changes to ensure the app remains compatible. More frequent and drastic OS updates mean higher adaptive maintenance costs.

Size and Engagement of the User Base: A larger, more active user base means more server resources are needed, more customer support is required, and any bugs or outages will have a bigger impact, necessitating faster, more costly fixes.

Number of Features & Third-Party Integrations: Every third-party service (payment gateways, social media APIs, and map services) requires its own maintenance. When these services update their APIs, your app needs to be updated too, which adds to the cost.

Security and Compliance Requirements: Apps in regulated industries like healthcare (HIPAA) or finance (PCI DSS) have stringent security and compliance requirements. Regular audits, penetration testing, and security updates are mandatory and come with a hefty price tag.

Average App Maintenance Cost Breakdown in 2025

While exact costs vary, here’s a general cost breakdown based on app complexity in 2025. These figures are based on hiring a development team from a region with moderate rates (e.g., Eastern Europe or parts of Asia), which can be a highly cost-effective option without sacrificing quality.

1. Cost for Small Apps

Examples: Simple utility apps, informational tools, calculators, or a single-feature MVP (Minimum Viable Product).

Characteristics: These apps are often straightforward and standalone. They have a limited number of screens and features, require minimal user interaction, and typically don’t rely on complex server-side processing or third-party APIs like payment gateways or social logins. Their user base is generally small to moderate.

Maintenance Needs:

• Corrective Maintenance: Fixing minor bugs and crashes that appear after launch.
  
• Adaptive Maintenance: Updating the app to remain compatible with new operating system versions (future iOS and Android versions) and new device models.
