How much does a custom web app cost?

By Fahad Tariq, founder of Zirah Tech · Published November 3, 2026

Four agency guides price a medium-sized business app at $38,400, $45,000 to $120,000, $50,000 to $150,000 and $50,000 to $150,000. So how much does a custom web app cost? Between $5,000 and $350,000+ depending on who you ask, and the spread comes from a few things you can control.

Published prices for a custom web app run from $5,000 to $350,000+, and guides disagree

A custom web app is software people use in a browser to do work: sign in, see their own data, take actions. A brochure site is not one. Clutch, which collects prices from verified client reviews, shows how wide the market is. Software projects on its platform most often cost $10,000 to $49,999, with an average of $132,480.29 pulled up by large projects and a typical timeline near 13 months. Web development projects most often cost under $10,000, with an average of $66,499.09 and a typical timeline near 9 months. Both figures cover software or websites in general, not only custom web apps.

Agency guides slice the app market into tiers. Here is what four of them say.

SpdLoad adds that US rates around $150 an hour could push a complex build past $200,000. The pattern: simple tools land in the tens of thousands, not hundreds, and the top end has no ceiling. Guides also contradict themselves. One lists single-page apps at $90 to $400 and also at $1,500 to $10,000 on the same page (eSparkBiz). Treat every range as context, then build your own number.

A narrow tool can come in lower. One guide says going under $10,000 is realistic only for narrow tools, configured platforms or a freelancer working from a tight written scope (Articsledge).

Your build cost is hours times rate, plus a buffer

Every estimate reduces to the same math, and you can run it before you talk to anyone.

Build budget = (hours x blended hourly rate) + one-time costs + buffer

SpdLoad's table is the cleanest example: 480 hours at $40 an hour is $19,200. Netguru's tiers use hours too: 200 to 500 hours for a simple build, 500 to 1,200 for a medium one, 1,200 to 3,000 for a complex one, at a blended $75 to $150 an hour. Articsledge suggests a 10% to 20% buffer for uncertainty, and a low, expected and high case. The hours tell you more than the headline number does. Ask each vendor for hours by phase and the rate behind them.

Where the hours go: Flatlogic puts development at 40% to 55% of the total, design at 15% to 25%, discovery and planning at 10% to 15%, testing at 10% to 20% and deployment and maintenance at 10% to 20%. If a quote has no line for testing or planning, ask why.

Late requirements move the price more than features do

"Login" can mean one email field or social sign-in, multi-factor security and permission layers. Flatlogic names five scope factors: core functionality, user roles, integrations, data complexity and scale. Articsledge adds data migration, payments with refunds, vague requirements and mid-build changes.

Netguru's guide makes the sharpest point: the first quote prices the visible feature list, then compliance and non-functional needs rewrite it. Its examples are its own engagements (vendor data, not a study): a $90,000 portal estimate that tripled once health-data handling and a legacy system integration surfaced, and an estimate that moved from about $45,000 to over $150,000 once a compliance requirement and audit logging appeared. Read those as cautionary anecdotes, not averages.

The fix is cheap. Before you fix a budget, write down: who must be allowed to see what, which outside systems must connect, whether health, payment or EU personal data is involved, and how many users you expect in year one. Each answer changes the hours.

A low hourly rate can cost more than a higher one

Rates are inputs, not prices. Clutch lists most software development companies at $25 to $49 an hour, with US providers at $50 to $99 for software and $100 to $149 for web development, and Canada and Australia at $100 to $149. Netguru's 2026 blended agency bands run $100 to $180 for the US and Canada, $45 to $85 for Eastern Europe and $20 to $45 for South Asia. eSparkBiz lists freelancer rates starting at $15 to $50 in India and $35 to $80 in Latin America. These are vendor and listing figures, a sanity check only.

Employee pay is not a billing rate either. The US Bureau of Labor Statistics reports a median annual wage of $135,980 for software developers in May 2025, before benefits and management.

The better test is total cost for the same written scope. Articsledge gives an example: a $60-an-hour team that needs 160 hours because of rework costs $9,600. An $85-an-hour team that needs 100 hours costs $8,500. Rework, delays and unclear ownership of the code can erase a low rate. Fixed price suits a clear, stable scope. Time and materials suits changing requirements but needs a cap and weekly reports. Ask which one the quote uses and who pays for changes.

Budget 15% to 25% of the build per year to keep it running

The build quote is the first bill, not the last. After launch you pay for hosting, backups, monitoring, third-party services, bug fixes, security updates and support.

Sources do not agree, which is useful to know. Netguru gives an industry rule of thumb of 15% to 25% of the initial build per year. A Google snippet from Elegant Media says the same range, and one from Lizard Global says 15% to 20% (snippets only). Articsledge's hypothetical model assumes 10% of the base build per year for maintenance and then adds hosting and enhancements on top. Pick a range, then ask the vendor for a monthly figure in writing.

Hosting depends on use. Netguru says a low-usage internal tool might run $50 to $200 a month on serverless hosting, while a customer-facing app with steady load looks more like $1,500 to $6,000 (vendor estimates). Watch per-call and per-payment fees too.

Also settle who owns the code and holds the hosting credentials. At Zirah Tech, the client owns the code, accounts and docs, and the code goes in the client's repo from day one. Ask every vendor for the same.

Cut the first version, not the quality

The biggest lever is what you leave out of version one:

• One workflow first. Launch the thing users cannot do today. Add the rest after you see real use.
• Two roles, not five. User and admin cover most first releases (Flatlogic).
• Reuse proven tools for sign-in, payments and email instead of building them.
• Check alternatives first. If a configured SaaS tool, a no-code app or a simple integration already does most of the job, buy that. Build only when your process is unique or the alternative keeps failing (Articsledge). One MVP guide quotes $3,000 to $10,000 for no-code mobile MVPs (ThinkMobiles, snippet only).
• Defer data migration. Start with fresh data and import old records later.
• Let AI tools trim boilerplate, with review. Netguru's own data shows 25% to 35% fewer hours on standard CRUD features, savings that disappear if generated code is merged without review (vendor data).

Do not cut testing, security checks or accessibility to hit a number. They cost less before launch than after a failure (Articsledge).

Put these items in the brief before you ask for quotes

Quotes are only comparable when vendors price the same document. A one-page brief is enough:

1. The business problem in two sentences.
2. Who uses it and what roles exist.
3. The three to five workflows that must work on day one.
4. Systems it must connect to (payments, CRM, email).
5. Sensitive data involved (health, payment, EU personal data).
6. A budget range and a target date.
7. How you will judge success, for example hours saved per week.

Then ask for assumptions, exclusions, milestones, the change process, who owns the code and what happens at exit. A quote with no exclusions deserves questions.

If you want a second pair of eyes on the brief, Zirah Tech runs a free 30-minute call, followed by a written proposal with milestones, a timeline and either a fixed price or a retainer. Book the intro call or read how the work runs.

FAQ

How much does it cost to develop an app? Published guides range from about $5,000 to $350,000+ for a custom web app. Clutch reports that most software projects it lists cost $10,000 to $49,999. Your number depends on roles, integrations, data and compliance. Use the hours x rate x buffer formula.

Is $1,500 a good price for a website? For a simple brochure site, possibly. For a web app with logins, roles and integrations, no. One guide says client logins, several roles and integrations rarely fit under $10,000 (Articsledge). A $1,500 quote for a full app deserves close questions about what is left out.

How much does it cost to maintain a web app? Industry guides suggest 15% to 25% of the build cost per year (Netguru), plus hosting and service fees that scale with use. A hypothetical model from Articsledge uses 10% for maintenance alone. Ask your vendor for a monthly figure in writing.

How much should I pay a web app developer per hour? Clutch lists most software development firms at $25 to $49 an hour, with US firms at $50 to $99 for software and $100 to $149 for web development. Compare total cost for the same written scope, not the rate.

Is a freelancer cheaper than an agency? Per hour, often yes. An agency adds design, testing, project management and capacity. Compare total cost for the same scope, plus what happens if one person is unavailable.

How long does it take to build a custom web app? Flatlogic cites 1 to 3 months for simple apps, 3 to 6 for mid-level and 6 to 12+ for complex ones. Clutch's reviewed projects average about 9 months for web development and 13 for software. Feedback speed and scope changes move the date more than coding speed.
