How much does mobile app maintenance cost?

 Mobile app maintenance typically costs 15–20% of the original development budget annually. If your app cost $100,000 to build, expect $15,000–$20,000 per year in maintenance, or roughly $1,250–$1,666 per month.

Cost by development budget:

• $20,000 app: $3,000–$4,000/year ($250–$333/month)
• $50,000 app: $7,500–$10,000/year ($625–$833/month)
• $100,000 app: $15,000–$20,000/year ($1,250–$1,666/month)
• $250,000 app: $37,500–$50,000/year ($3,125–$4,166/month)

Most businesses spend $500–$4,000/month overall, depending on complexity. This covers bug fixes, hosting, OS compatibility updates, security patches, and performance monitoring — not one-time app store fees ($99/year Apple, $25 one-time Google Play) or analytics tools, which businesses often forget to budget separately.

The first year post-launch is usually the most expensive, since it absorbs real user feedback, unexpected bugs, and early performance issues that don't surface in QA.
