June 13, 2025
Launching your app isn’t the finish line — it’s the start of the next bill. Bug fixes, updates, server costs — they don’t stop once you hit “go live.” In fact, year one can eat up 50% of your original dev budget.
Want to stay ahead of those creeping costs? Let’s break down what app maintenance really costs in 2025 — and how to avoid burning cash where you don’t have to.
Application Maintenance and Support: What It Actually Costs in 2025
Shipping an app is only half the bill. Once the product is live, founders face an annual spend that averages 15–20 % of the original development budget—and can spike to 50 % in the first year when bug-fix sprints, OS updates, and security patches converge.
Example: a New York fintech launched its MVP for $200 k in May 2024. By April 2025 it had poured another $95 k into maintenance:
- $38 k for PCI-DSS compliance updates after new Stripe policies
- $27 k for bug fixes and crash analytics after user growth tripled
- $18 k on cloud scaling and observability tools
- $12 k on App Store and Google Play policy changes
That second budget isn’t a one-off; it’s the price of staying live, secure, and competitive. The rest of this article details every line item, shows current 2025 benchmarks across app types, and explains how to predict your own maintenance runway before surprises hit.
What Is App Maintenance — and Why Skipping It Wrecks Apps in 2025
Mobile and web apps run in a moving ecosystem: new OS releases, cloud-API changes, fresh security threats, tighter data rules. Maintenance is the work that keeps your code standing when those tectonic plates shift.
The 2024 Instabug Mobile App Stability Outlook shows a stark correlation: apps that hold a 99 %+ crash-free rate keep 42 % more monthly active users than those that dip below 97 %.
Skip any of these layers and the costs show up fast: lower store ratings, higher churn, support overload, even compliance fines. Maintenance isn’t overhead—it’s the insurance that keeps your product earning instead of burning.
How Much Does App Maintenance Cost per Year? (2025 Benchmarks)
Most founders budget hard for the launch — and then get blindsided by the second bill: ongoing maintenance. But this part isn’t a surprise. It’s predictable, if you know what to expect.
What that looks like in real numbers:
In year one, costs spike because:
- Real users report edge-case bugs that QA missed
- Apple or Google roll out policy or OS changes
- You tweak features based on early feedback
- You need monitoring, alerts, backups — all the things that don’t matter until they really do
Before you crunch maintenance numbers, sanity-check your initial budget.

Real-world example:
A SaaS team launched a $90K product. In the first 12 months, they spent $38K more:
- $14K on payment system updates after Stripe’s policy change
- $9K to scale AWS after traffic tripled
- $8K fixing bugs from heavy enterprise onboarding
- $7K on legal work to pass SOC 2 compliance
None of it was “extra.” It was the cost of staying live, secure, and usable.
SMB vs Enterprise:
- Simple B2C or SMB apps with Firebase, Stripe, and managed hosting usually sit in the $5K–$11K/year range.
- Enterprise apps — custom backend, compliance requirements, SLA-bound — often hit $30K+ just to stay operational.
If you ignore these numbers in planning, you're not saving — you're just setting up for surprise scope creep and fire drills.
First-Year Spike: Why Year 1 Can Hit 50 %
The first 6–12 months after launch are the most volatile — not because your code is bad, but because real-world conditions hit fast and hard.
You’re not just fixing bugs. You’re responding to live data, platform policies, and users doing things no one tested for.
Here’s what typically eats into your budget in Year 1:
🧭 Tech stack shifts mid-flight
That third-party API you relied on? They deprecated two methods a month after launch. Now you’re rewriting critical flows under pressure.
🔐 Store compliance isn’t static
Apple and Google update policies quarterly. In 2025, several apps were pulled from the App Store over vague tracking disclosures — even though they'd passed review three months earlier.
📈 User behavior forces rework
Your onboarding seemed clear in staging. But in production, 37% of users dropped before completing step 2. Reworking the flow took 3 sprints — and that’s before analytics flagged friction in checkout.
🔄 Infrastructure grows with your audience
You planned for 10K users. You got 40K. Now your monitoring stack is overloaded, and AWS bills have doubled. Scaling isn’t just infra — it’s time, people, and money.
These aren’t bugs. They’re growth pains. And unless you plan for them, they’ll feel like emergencies — every single time. That’s why experienced founders always overbudget Year 1.
What Do App Maintenance Costs Actually Cover?
A healthy maintenance budget tracks where money disappears each month. Below is a realistic split many product teams use in 2025. Adjust percentages as your scale, compliance load, and traffic grow.
Why this matters:
- Neglect observability and you’ll pay in user churn when crashes stay invisible.
- Skip security updates and the penalty arrives as regulatory fines or customer departures.
- Ignore cloud tuning and your AWS invoice balloons faster than user growth.
Knowing these buckets lets founders budget deliberately instead of reacting to surprise invoices.
How to Calculate Your Maintenance Budget (DIY Formula)
1) Baseline upkeepChoose a coefficient that matches your app’s complexity:
- Lightweight MVP → 0.14
- Mid-range product → 0.18
- Enterprise stack → 0.22
2) Annualise your variable ops spend
(averagemonthlycloud+averagemonthlythird−partyAPIs)×12(average monthly cloud + average monthly third-party APIs) × 12(averagemonthlycloud+averagemonthlythird−partyAPIs)×12
3) Add scheduled compliance events
Certifications, audits, or mandatory security reviews planned for the year.
Maintenance $ = (Initial Dev Cost × Coefficient) + Annualised Ops Spend + Compliance Events
How Often Do Apps Need Maintenance? (Cadence Map)
A live app is a moving target. Below is a practical cadence most product teams follow in 2025. Adjust the tempo if your industry is more regulated or if user growth spikes.
OS-Update Pressure
iOS 18 / Android 15 betas typically drop in June, with public release by September. Teams that test on beta build cut compatibility bugs by up to 70 % and avoid the mad sprint that hits many apps each fall.
Treat maintenance like a playbook, not an afterthought. Consistent cadence keeps fixes cheap and predictable—whereas skipping even one quarter can snowball into emergency rewrites and store takedowns.
Fixed vs Ongoing Costs — Keep the Fire (Not the Cash) Under Control
Think of your budget like a campfire:
1. Fixed “pilot-light” costs – the logs that smoulder no matter what.
- Apple & Google developer programs (≈ $100 / yr)
- A couple of small cloud instances to keep the API awake
- Baseline tooling: CI minutes, uptime pings, automated backups
Figure $12 k–15 k per year just to keep the lights on. Boring money, essential insurance.
2. Ongoing “flame” costs – the extra bundles you throw on as the party grows.
- Every user hits APIs, writes data, triggers push messages
- Cloud spend scales once you blow past free tiers
- Stripe, Twilio, OpenAI bills ride on usage
- Support hours creep up as tickets roll in
Plan on $0.15–0.25 per active user per month for these moving parts and tweak as real numbers flow in.
Runway sanity check:
25 k monthly active users at $0.20 each plus that $15 k fixed floor = ≈ $60 k a year. Double the users, double the variable slice—unless you optimise.
Track the two buckets separately. Miss the distinction and the 2 a.m. AWS-overage email will sting harder than any bug report.

Offshore vs In-House: Where Is Maintenance Cheaper?
Hiring local talent feels safe, but the price gap in 2025 is too wide to ignore. A senior mobile engineer in San Francisco still bills $120–150 an hour; the same profile in Warsaw or Bangalore comes in at $35–55. Even after you pad the offshore number for overlap meetings and code reviews, the math tilts hard.
Below is a realistic spread for routine maintenance (think 40 hours a month: bug fixes, store updates, infra tweaks).
Rule of thumb: Multiply the hourly rate by 1.5 if you need senior-level devs who can work with minimal guidance; subtract 10 % if you’re comfortable with mid-level engineers under strong technical leadership.
Quick runway test
- Bay Area in-house: $5 000 / mo retainer ≈ $60 k / yr
- Eastern Europe remote: $1 800 / mo retainer ≈ $22 k / yr
- Savings: $38 k a year — roughly another six-month runway for a small startup.
Offshore isn’t always the answer (complex compliance, low latency, or heavy live-ops can argue for in-house), but for routine maintenance most startups can cut costs by half to two-thirds without trashing code quality — provided they invest in clear requirements, automated tests, and timezone-friendly rituals (daily async stand-up, weekly live demo).
Comparing retainers is half the story—up-front build quotes hide landmines too. Read next: In-House vs Outsourcing: The 2025 Cost Smack-down.
Case Snapshots: 3 Start-Ups That Cut Maintenance 30 %
1. Fintech / Berlin — Preventive Audit Wins
A seed-stage payments app was burning €22 k a year on reactive bug-fix sprints. They hired an external code-quality auditor for a one-off €3 k engagement. The audit surfaced four memory leaks and a redundant logging package that inflated cloud writes. After two weeks of refactor work, crash rates dropped 43 % and their annual maintenance budget fell to €15 k — a 32 % saving.
2. B2B SaaS / Toronto — Cloud Swap Play
A metrics dashboard ran entirely on on-demand AWS EC2. Engineers moved 80 % of traffic to Graviton reserved instances and shifted cold storage to S3 Glacier. Infra spend slid from US$2 100 to US$1 200 a month. With zero user-facing changes, yearly maintenance costs shrank 34 % and the team redirected the surplus into feature development.
3. Marketplace / Sydney — Offshore Retainer Shift
The company kept two local contractors on a rolling support contract at AU$140/h. They replaced that model with a vetted Eastern-European team at AU$55/h, keeping a Sydney PM for release approval. Weekly maintenance hours stayed flat (≈12 h), but the monthly bill fell from AU$6 700 to AU$2 700 — 60 % cheaper. After accounting for new PM oversight, overall maintenance still ended up 31 % lower year-over-year.
FAQ: Application Maintenance and Support Costs
How much does software maintenance cost per year?
Plan on 15–20 % of the original build cost. A $100 k app usually runs $15–20 k yearly; complex enterprise code can edge higher. This covers patches, cloud, small UX tweaks—anything that keeps the product stable and compliant.
Do I have to pay just to keep an app live?
Yes. Even idle apps rack up fixed bills—store fees, base cloud instances, log retention—often $1–2 k a month. Skip these and the app is pulled or the backend shuts off, taking your user data with it.
What are the typical fixed versus variable costs?
Fixed: Apple/Google programs, starter cloud footprint, core monitoring—about a quarter of the upkeep budget. Variable: API calls, autoscaling servers, support tickets. Those grow with active users and can double in a busy quarter if traffic spikes.
How much should I charge clients for maintenance as an agency?
A common model is 8–12 % of build cost per year on a retainer, plus pay-as-you-go for new features. For a $250 k project that’s $20–30 k annually, covering updates, monitoring, and priority bug fixes within an SLA.
How long does app maintenance take each month?
Expect 25–40 developer hours for a mid-size product. That includes weekly crash triage, a couple of hotfixes, dependency updates, and a small UX polish. Heavy compliance or high user growth can push the number above 60 hours.
