"How much will it cost?" is the first question every founder asks, and the honest answer is: it depends on scope, team, and how disciplined you are. But "it depends" is useless when you're planning a budget or raising a round. So here are real ranges, the factors that move them, and the discipline that keeps the number from spiraling. The goal of an MVP isn't to build your product — it's to learn whether the product is worth building. Price it accordingly.
What actually drives the cost
An MVP's price is almost entirely a function of how many distinct flows it contains. Each flow — signup, billing, a dashboard, an admin panel — is design, front end, back end, and testing multiplied out, then integrated and QA'd. The number that matters is not "features" but screens times integrations times states. A single screen has a loading state, an empty state, an error state, a success state, and a mobile layout. That's five things to design and build, not one — and it's where estimates that "felt about right" quietly double.
The three biggest cost drivers we see, in order:
Auth and billing. Payments, subscriptions, proration, dunning, tax, and the "what happens when a card fails" edge cases look simple and never are. Budget real time here — it's the plumbing that touches money, so bugs are expensive and trust is fragile. Our payment gateway integration guide covers the traps.
