In short: an in-house full-stack developer costs a salary plus benefits, equipment and management time, and only makes sense if you have years of steady work. Freelancers are flexible, and their rates vary enormously with experience. A small agency or team quoting a fixed price costs more per hour on paper, but you pay for an outcome and the risk of the estimate is theirs. Choose by how much work you have and how much risk you can carry, not by hourly rate alone.
"How much does a full-stack developer cost?" sounds like a simple question, but the answer depends on how you hire. A salary, an hourly rate and a fixed project price are three different things, and comparing them directly is how many businesses end up paying more than they planned.
This guide compares the three main ways to hire, with real reference numbers where reliable ones exist, and the costs that usually do not appear in the first quote.
What a full-stack developer actually does
A full-stack developer works on both sides of a product. On the frontend, they build what users see and click, usually with React or Next.js. On the backend, they build the server, database and APIs that store data, handle logins and payments, and connect to other services. Many also handle deployment: hosting, environments and monitoring.
That breadth is the appeal. One person, or one small team, can take a feature from idea to production without handing it between specialists. It also means skill levels vary widely: someone who has built a few websites and someone who has run a production web app for years can both call themselves full-stack.
Option 1: hiring in-house
For reference, the US Bureau of Labor Statistics reports a median annual wage of $133,080 for software developers (May 2024, BLS Occupational Outlook Handbook). Salaries in the UK, Canada and most of Europe are lower in absolute terms, but the pattern below is the same everywhere.
The salary is only part of the cost. Budget for:
- Employer costs: payroll taxes, pension contributions, health insurance or other benefits, depending on the country.
- Recruiting: job ads or agency fees, plus the hours your team spends interviewing.
- Equipment and tools: a capable laptop, software licences, hosting and developer services.
- Ramp-up time: new developers need weeks to learn your product before they are fully productive.
- Management: someone has to set priorities, review work and make technical decisions.
In-house is the right choice when you have a product that needs continuous development for years, and enough work to keep a developer busy every week. It is rarely right for a one-off website or a first version of an app.
Option 2: hiring a freelancer
Freelancers charge by the hour or by the project. Upwork's own rate guide says intermediate professionals in most categories charge around $25 to $75 an hour, while specialised development work often reaches $75 to $150 an hour or more (Upwork hourly rates guide). Where the developer lives, their experience and their reviews move the number a lot.
A good freelancer can be excellent value. The risks are practical rather than about skill:
- One person, one point of failure. Illness, holidays or a better-paid project can stop your work overnight.
- Hourly billing puts the estimate risk on you. If the job takes twice as long as expected, you pay twice as much.
- Coverage gaps. Many freelancers are strong on the frontend or the backend, but not both, and few also handle design, SEO and hosting.
- Vetting takes time. Portfolios and reviews help, but a short paid trial task is the only reliable test.
Option 3: a small agency or team on a fixed price
A small team quotes a fixed price for a defined scope. You know the cost before work starts, and if their estimate is wrong, they absorb it. Because a team covers design, frontend, backend and deployment, there is no gap between specialists, and work does not stop when one person is away.
The hourly equivalent is often higher than a freelancer's rate, because the price includes project management, testing and the risk of the estimate. The total is often lower than people expect, because experienced teams reuse proven setups and do not bill for learning.
For example, our own published packages start at $499 for a starter website, $999 for a business website, $1,749 for an online store and $3,000 for a custom web app with logins, roles, a database, an API integration and an admin panel. Ongoing development is quoted as a monthly plan. See our full-stack development service for what is included.
The hidden costs, whichever way you hire
- Unclear scope. The most expensive line in any software budget is "while you are at it". Write down what the first version must do, and what can wait.
- Rework from skipped design. Building before agreeing screens and flows means paying to build things twice.
- No tests, no handover. Code without tests or documentation becomes expensive the day the original developer leaves.
- Ownership. Make sure the code repository, hosting and domain accounts are in your name, not the developer's.
- Maintenance. Every product needs security updates and fixes after launch. Budget for it from the start.
Which option is right for you?
| Your situation | Usually the best fit |
|---|---|
| A website or a first version of an app, with a clear scope | Fixed-price team |
| Small, well-defined tasks on an existing system | An experienced freelancer |
| A product with years of continuous development ahead | In-house, often with outside help at the start |
| A product whose only developer has left | A team that can review the code and take over |
Whatever you choose, ask for three things before you sign: a written scope, a price or estimate tied to that scope, and confirmation that you will own the code and accounts.
Frontend, backend or full-stack?
If your work is mostly interface, such as turning designs into fast, accessible pages, a frontend developer may be all you need. If it is mostly APIs, databases, payments and integrations, look for backend developers. For a product that needs both, a full-stack team avoids the handoffs between the two, which is where many bugs and delays start.
