Maintenance Economics
App Maintenance Cost
Maintenance is not optional. It is only ever deferred.
Operating systems, SDKs, dependencies, and store policies all change on someone else’s schedule. The bill arrives either way.
Quick Answer
Updated August 22, 2026
How much does app maintenance cost per year?
App and software maintenance costs 15–20% of the original build cost per year — so $3,000–$8,000 annually on a $40,000 app, or ₹3–8 lakh on a ₹25 lakh build. That covers OS and SDK compatibility, dependency and security updates, store policy changes, bug fixes, and monitoring. It does not cover new features. Skipping maintenance does not save the money; it defers it into a larger remediation project, and unmaintained mobile apps typically break within eighteen months.
Annual cost
15 – 20% of build cost
Mobile retainer
$800 – $3,000 / month
Unmaintained app
Typically breaks within 18 months
Best for
- Products with real users who expect the app to keep working
- Companies that would rather budget than be surprised
- Apps in stores, where policy changes are enforced by removal
Not best for
- Prototypes and internal tools with a known end date
- Products being deliberately sunset
- Static sites with no dependencies to speak of
Price Bands
What app maintenance costs, by scope
Bands rather than a single figure, because a single figure without the assumptions behind it is a sales number rather than an estimate.
| Tier | Scope | INR | USD | Timeline | Team |
|---|---|---|---|---|---|
| EssentialStable products that mainly need to keep working | Security patches, dependency updates, critical bug fixes, uptime monitoring | ₹65,000 – ₹1,20,000 / month | $800 – $1,500 / month | Monthly rolling | Shared engineer |
| StandardLive products with active users and regular small changes | Everything above plus OS compatibility, store releases, small changes, support SLA | ₹1,20,000 – ₹2,50,000 / month | $1,500 – $3,000 / month | Monthly rolling | 0.5 engineer |
| Continuous deliveryProducts still growing, where the roadmap does not stop | Maintenance plus ongoing feature development and roadmap capacity | ₹2,50,000 – ₹5,00,000 / month | $3,000 – $6,000 / month | Monthly rolling | 1 engineer |

Cost Breakdown
Where the budget actually goes
| Phase | Share | What it covers |
|---|---|---|
| Dependency and security updates | 25 – 30% | Libraries ship security patches constantly; staying current is cheaper than catching up. |
| OS and platform compatibility | 25 – 30% | Annual iOS and Android releases, plus SDK deprecations with hard deadlines. |
| Bug fixes | 20 – 25% | Issues real users find that testing did not. |
| Monitoring and incident response | 10 – 15% | Alerting, crash triage, and responding when something goes wrong. |
| Small changes | 10 – 15% | Copy, configuration, and minor adjustments that do not warrant a project. |
Cost Drivers
What changes the price, and by how much
If two quotes for app maintenance differ wildly, the cause is almost always one of these being assumed in or out.
Mobile versus web
Two operating systems on annual release cycles, plus store policy enforcement.
Number of integrations
Every third-party API is another party who can change something without asking.
Age of the codebase
Deferred maintenance compounds. Catching up costs more than staying current.
Compliance requirements
Regulated products need documented patching, access reviews, and evidence.
Response time expectations
A four-hour SLA costs more than best-effort during business hours.

After Launch
What it costs to keep running
The line most quotes leave out, and the one that decides whether the product is still alive in two years.
| Item | Cost | Notes |
|---|---|---|
| Web application | 10 – 15% of build cost / year | One platform, slower change cadence than mobile. |
| Mobile application | 15 – 20% of build cost / year | Two operating systems, annual releases, and store policy enforcement. |
| Regulated product | 20 – 30% of build cost / year | Documented patching, access reviews, and periodic penetration testing. |
How We Quote
From a brief to a number you can plan against
Step 1
You send a written scope
A feature list, an existing product, or a problem statement. Anything we can read and ask questions about.
Step 2
We ask the questions that move the number
Roles, integrations, compliance, and volume. These change a quote far more than the interface does.
Step 3
You get a banded estimate, not a single figure
A range with the assumptions written next to it, so you can see which assumption to challenge.
Step 4
We recommend the lightest shape that works
Fixed-scope, phased, or a dedicated pod. We say when a smaller engagement would serve you better.
Prefer to work it out yourself first? The project cost estimator gives you a band in a couple of minutes, and the MVP scope planner helps you work out what to cut before you ask anyone for a quote.

FAQ
Pricing questions we get asked most
How much does app maintenance cost per year?
15–20% of the original build cost annually for mobile apps, 10–15% for web applications, and 20–30% for regulated products. On a $40,000 app that is $4,000–$8,000 a year.
What happens if we skip maintenance?
For mobile, the app typically breaks within about eighteen months — an OS release changes behaviour, an SDK is deprecated, or a store policy is enforced and the app is removed. For web, security vulnerabilities accumulate in dependencies. Neither saves money; both defer it into a larger remediation project.
Does maintenance include new features?
No. Maintenance keeps what exists working. New features are separate work, quoted separately. Any retainer claiming to include unlimited features is either underspecified or being priced for the worst case.
Can our in-house team handle maintenance?
Yes, if they have the platform knowledge and the capacity. Maintenance is unglamorous and gets deprioritised against feature work, which is precisely why it is often better as a separate retainer with its own budget.
Can we pause maintenance and resume later?
You can, and catching up costs more than continuous coverage would have. Six months of deferred dependency updates typically takes two to three times the effort of doing them as they arrived.
