App Maintenance Cost Calculator (2026)

01

Cost at a glance

Typical monthly Aalpha prices for three common plans, next to what a US agency usually charges for the same hours.

Complexity	Typical scope	Aalpha	Monthly hours	US agency
Essential	One web app: bug fixes, security patches, backups, uptime monitoring and a monthly report	$500 – $1,000	44 h / month	$4,500 – $8,000
Growth	Web and mobile apps with hosting, store releases, small enhancements and extended-hours support	$2,000 – $3,500	135 h / month	$13,500 – $24,000
Enterprise	Several products, 24/7 critical support, performance work and regulated-data controls	$4,500 – $7,000	288 h / month	$29,000 – $52,000

Estimates. The final cost depends on the scope of work we agree.

How the estimate is calculated

We count hours first and then price them at one blended rate. The four steps below use the options you picked in the calculator, so the numbers match your estimate.

Per month44 h / month

Formula. Cost = [ Build × (1 − AI) + Design + Discovery + QA + Launch ] × 1.10 × Rate, where Build = (Scope × 0.6 × App support + Scope × 0.4 × Codebase) × Compliance. The result is a monthly retainer; Review is a fixed 4 hours and Releases are 4 hours per platform factor.

Where AI saves time

Our engineers use AI coding assistants for scaffolding, repetitive UI, API boilerplate, unit tests and documentation. A senior engineer reviews every AI-generated change before it is merged. On our projects this cuts hands-on build time by about 40%, and your estimate includes that saving.

We don't discount incident response, release decisions, client communication and account management, because people still do that work in full.

What affects the cost

Six things move the price of app maintenance. Each one maps to a step in the calculator.

What we support

App-side work is about 60% of monthly hours. Each extra platform adds its own updates, testing and releases.

× 1.00 web · × 1.25 mobile · × 1.60 web + mobile · × 2.20 multiple products

Services

Each service has a monthly hour benchmark. Every plan includes 12 hours a month of monitoring and health checks.

From 3 h (backups, reports) to 24 h (enhancements) a month

Support hours

Faster response times need engineers on standby outside business hours, priced as a share of engineering hours.

5% business hours · 15% extended · 35% 24/7

Codebase condition

Codebase and infrastructure work is about 40% of hours. Code we built is fastest to support. Legacy or undocumented code takes longer to change safely.

× 0.80 Aalpha-built · × 1.00 documented · × 1.35 legacy

Integrations

Each monitored integration is checked for failures, expiring credentials and API version changes.

3 h per integration a month

Compliance

Regulated data adds access reviews, audit evidence and stricter change control every month.

Cost in India compared with other countries

The same 44 monthly hours, priced at typical agency rates in each region. Only the hourly rate changes.

Region	Typical rate	Monthly cost	vs Aalpha
Aalpha (India)	$15–$25/h	$500 – $1,000	Baseline
Eastern Europe	$35–$60/h	$1,500 – $2,500	2.4× the cost
Latin America	$35–$65/h	$1,500 – $3,000	2.5× the cost
Australia	$90–$150/h	$4,000 – $6,500	6.0× the cost
Western Europe & UK	$70–$130/h	$3,000 – $5,500	5.0× the cost
United States	$100–$180/h	$4,500 – $8,000	7.0× the cost

Why India costs less

Operating and living costs are lower, so rates are lower at the same seniority.
India has one of the largest pools of software engineers in the world.
The outsourcing industry is well established, with standard delivery, security and contract practices.

What to check with any offshore team

How many working hours overlap with yours, and who your daily contact is.
Who owns the code, what the NDA covers and how access to your data is controlled.
References and live products in your industry.

How Aalpha handles it

A dedicated project manager whose hours overlap with US, UK, EU and Middle East clients.
An NDA before kickoff, and full transfer of source code and IP to you.
Case studies and references from clients in 55+ countries.

Frequently asked questions

How much does app maintenance cost per month in 2026?

At Aalpha's rate of $15 to $25 an hour, with AI-assisted delivery, essential care for one web app costs about $650 to $1,100 a month, a growth plan for web and mobile apps $2,000 to $3,350 a month, and enterprise support $4,300 to $7,200 a month or more. These are estimates, and the final plan depends on the scope of work we agree.

What percentage of development cost is maintenance?

A common rule of thumb is 15 to 20% of the original build cost per year. This calculator works from the services you actually need, which is usually more accurate.

Can you take over an app built by another company?

Yes. We start with a code and infrastructure audit, document what we find and fix urgent issues first. Undocumented code uses the legacy factor in this calculator.

Do unused hours roll over?

On most plans, unused enhancement hours roll over for one month. We agree the rules in the support agreement.

What isn't included in the estimate?

Hosting and cloud bills, app store fees, paid third-party services and large new features, which we quote separately.

Why might the final quote differ from the calculator?

The calculator uses typical scope for each item. When we review your requirements, the price can come down, for example if we reuse existing modules or simplify a flow. It can also go up if there are complex business rules or legacy systems. We send a fixed quote after a free discovery call.

Why is development cheaper in India?

Operating and living costs are lower, the pool of software engineers is one of the largest in the world, and the outsourcing industry is well established. Together these let Indian firms charge much less than US, UK and Australian agencies for the same hours.

Can I get a fixed-price quote?

Yes. After a short discovery phase we agree a written scope of work, milestones and a fixed price. If you'd rather stay flexible, you can hire a dedicated team by the month.
