App maintenance costs: What companies should plan for each month after the launch

Short answer: You should expect these app maintenance costs

Realistic running budgets for B2B apps in Germany:

• MVP App: 300 to 1,500 euros per month
• Business App: 1,500 to 5,000 euros per month
• Enterprise App: 5,000 to 12,000 euros per month

These corridors typically include hosting, monitoring, security updates and minor developments.

Which cost components drive the monthly effort?

1. Hosting and infrastructure: Cloud, database, storage, backups
2. Monitoring and incident handling: Logging, alerting, troubleshooting
3. Maintenance and updates: Framework updates, store requirements, OS compatibility
4. Security and Compliance: Patches, rights concepts, technical documentation
5. Continuous product work: small improvements, conversion optimization, new features

Monthly maintenance models in comparison

MVP Operation

• Low number of users, few integrations, clear core process
• Updates and security fixes at predictable intervals

Typical frame: 300 to 1,500 euros per month

Business app operation

• Multiple roles, relevant integrations, higher usage frequency
• Regular release cycles and active monitoring

Typical frame: 1,500 to 5,000 euros per month

Enterprise operation

• Critical processes, high load, strict SLA requirements
• 24/7 monitoring, security routines, structured incident management

Typical frame: 5,000 to 12,000 euros per month

Three common post-launch budget mistakes

• Only hosting to be calculated: Personnel costs for maintenance and operation are then completely missing.
• No budget for store updates: iOS and Android requirements change regularly.
• To separate maintenance and feature expansion: In practice, stability and product work are intertwined.

FAQ: App maintenance costs

Conclusion: Running costs can be planned if the operation is taken into account early on

Those who treat app maintenance costs as an integral part of the product strategy have fewer failures and more development speed. What is crucial is a realistic monthly framework instead of a starting calculation that is too tight.
