Ask ten developers what an MVP costs and you'll get ten different numbers, some of them wildly apart. That isn't because anyone is lying. It's because "an MVP" can mean a clickable demo or a payments platform, and the price follows what's actually inside it.
Instead of a number that won't fit your situation, here's what moves the price up or down, and what you can do about each one before you ask for a quote.
Scope is the biggest lever by far
Every screen, every user flow and every edge case is work: design, code, testing and later maintenance. Two apps that sound similar in a pitch can differ by a factor of several once you list what each one does.
The features that inflate scope most quietly are the ones that seem small in conversation:
- Multiple user types, such as buyers and sellers, or admins and members, each with their own screens and permissions.
- An admin panel for your team to manage users, content or refunds.
- Notifications by email, SMS and push, each with its own settings and failure cases.
- Search and filtering across large amounts of data.
- Anything real-time, like chat, live updates or collaborative editing.
None of these are bad ideas. They're just rarely needed to prove that people want the product.
Integrations and data you don't control
Each outside service your app talks to adds setup, error handling and testing. Payment providers, calendars, CRMs, accounting tools, maps and AI models all have their own quirks, rate limits and ways of failing.
Well-documented, widely used APIs are cheaper to integrate than niche or legacy systems. If an integration involves a partner's internal system, an old SOAP API or a spreadsheet someone emails each week, expect it to take far longer than it sounds.
Money, compliance and sensitive data
Handling payments, health information, financial data or anything regulated raises the bar. It's not only the code. It's audit logs, access controls, encryption, data retention rules and sometimes legal review.
- Simple one-off payments through a hosted checkout are the cheapest option.
- Subscriptions add trials, upgrades, downgrades, failed renewals and refunds.
- Marketplaces that pay out to other people add identity checks, payout timing and disputes.
- Regulated data adds compliance work that has to be done properly from the start.
Who builds it, and how
Rates vary a lot between freelancers, agencies and in-house hires, but the hourly rate is a weak predictor of total cost. A slower, cheaper builder who needs every decision spelled out can cost more than a faster, more expensive one who makes good calls on their own.
The way the work is priced matters too. Fixed-price work shifts the risk of overruns to the builder, so it usually needs a tight scope. Hourly work is flexible, but the total is open-ended unless someone manages it closely.
The tools also changed the math. AI app builders and coding assistants make a first version much faster to produce. They don't remove the work of making it secure, reliable and maintainable, which is where much of the real cost lives.
The costs that come after launch
The build is only part of the picture. Budget for what keeps the app alive once people use it:
- Hosting, database and storage, which grow with users and data.
- Third-party subscriptions such as email delivery, error tracking and AI API usage.
- Bug fixes and small changes once real users find what testing missed.
- Security updates for frameworks and libraries, which never stop.
Ask any builder what ongoing costs to expect. If the answer is "nothing," keep asking.
How to bring the price down
- Write down the one question your MVP must answer, such as "will small agencies pay for this?", and cut every feature that doesn't help answer it.
- Replace features with manual work. You can approve accounts, send reports or match users by hand until volume makes it painful.
- Use off-the-shelf services for login, payments, email and file storage instead of building them.
- Start with one platform. A responsive web app usually beats building separate iOS and Android apps on day one.
- Decide quickly. Slow answers and changing requirements are among the most common reasons projects go over budget.
- Get a second opinion on the scope before you sign anything, so you're comparing quotes for the same thing.
How to compare quotes fairly
Quotes are only comparable when they describe the same work. Send every builder the same written scope, then ask each one what's included and what isn't: design, testing, deployment, documentation, and who owns the code and accounts at the end.
Be wary of a quote far below the others. It often means something important was left out, and you'll pay for it later.
If you want a clear scope before asking anyone for a price, Deeraf's Build Sprint starts from exactly that, and a Tech Check can tell you what an existing prototype still needs before launch.
