App Maintenance Costs in 2025 – The Full Breakdown
Contents
- 2 min read
Introduction: Launching Is Just the Beginning
In 2025, launching an app is only half the journey. The hidden cost many founders overlook is maintenance — the updates, bug fixes, compliance patches, hosting, and ongoing support that keep your app alive.
So how much does app maintenance cost in 2025?
The short answer: 15–25% of your initial build cost annually.
That means if your app cost A$100,000 to build, expect $15,000–$25,000 per year in ongoing expenses. For larger fintech or AI platforms, it can be significantly more.
This blog breaks down the numbers, what’s included, and how Digital One Agency makes app maintenance predictable with finance-backed support plans.
