A clickable prototype that covers 8-12 screens and lets investors tap through a core user flow typically costs between $3,000 and $8,000 if scoped correctly. The number jumps to $25,000-$60,000 when someone sells you a working build instead — which is usually not what you need at the idea stage. Understanding what actually drives prototype cost will help you read any quote you receive and ask the right questions before signing anything.
This post focuses on Figma-style interactive prototypes and the lightweight scoping work that should accompany them. Not a coded MVP. Not a design system. Just the thing you put in front of investors or first customers to test whether the idea holds up.
Why are most prototype quotes so much higher than they should be?
Two reasons. First, many agencies default to quoting a full build because that is what generates the most revenue for them. They hear "I need an app" and start estimating backend infrastructure, API development, and a staging environment. A prototype needs none of that.
Second, founders often do not know what to ask for, so they describe the product in full and get a full-product quote back. The agency is not necessarily being dishonest — they are just answering the question they were given.
The practical result is that a founder walks away thinking they need $80,000 to find out if their idea works. They usually do not. They need something a user can tap through, something that looks real enough to get a meaningful reaction from the room.
What actually drives app prototype cost?
There are three real variables. Scope is the biggest one. Fidelity is second. Integrations — even in a prototype — are third.
Scope (number of screens and flows)
A prototype is not a full product, but it does have to cover enough ground to be credible. For most consumer or B2B SaaS ideas, that means a core user flow from onboarding through the primary action the product exists to perform. That might be 8 screens or it might be 22. Every additional flow — admin panel, settings, reporting dashboard, secondary user role — adds time and cost.
A single-flow prototype covering the main job-to-be-done might take 40-60 hours of design time. Add a second user role (say, a clinic admin view alongside a patient view) and you are probably looking at 80-100 hours. The math is not complicated, but founders often do not realize they have described four distinct flows in the same breath.
Fidelity
Fidelity means how close the prototype looks and feels to a finished product. Low-fidelity means wireframes — grey boxes, placeholder text, enough structure to test a concept. High-fidelity means real brand colors, real copy, micro-interactions, and a visual design that could go straight to a developer as a spec. The gap in cost between those two endpoints can be $3,000-$5,000 on its own.
For investor pitches, high-fidelity is usually worth it. For early user interviews where you are still validating the concept, low-fidelity is often faster and more useful because people will tell you what is wrong with the flow rather than commenting on button colors.
Integrations
Most clickable prototypes in Figma do not hit real APIs. They simulate data. But some founders specifically need to show a live connection — a payment flow that actually processes a test charge, a calendar that pulls real availability, an EHR integration that surfaces a real patient record structure. That requires code, and code costs more than design. If an agency is quoting you for prototype-with-real-integrations, make sure you understand whether you actually need that for the stage you are at.
What should a prototype quote include?
A quote for a prototype without a build plan attached to it is only half useful. You will eventually need to know what the thing costs to build, what stack is appropriate, where the technical risk sits, and how long the first version will realistically take. If the prototype quote does not include that documentation, you will pay for it again later — or you will go into an engineering conversation without it and make expensive decisions without grounding.
A reasonable prototype engagement should include the interactive screens, a written explanation of the design decisions, and at minimum a high-level build plan with stack recommendations and a realistic cost range for the coded version. If you only receive a Figma file, ask what you are supposed to do with it next.
How to read a prototype quote line by line
| Line item | What to check |
|---|---|
| Discovery / scoping | Should be 4-8 hours. More than that for a prototype is padding. Less than that means they are guessing at scope. |
| Wireframes | Ask how many screens. Get a number. "As needed" is not a number. |
| High-fidelity design | Check whether this is per screen or a flat rate. Per-screen pricing is more honest for prototype work. |
| Prototype / clickthrough build | This is the Figma linking and interaction work. Should be a modest line, not the largest one. |
| Revisions | How many rounds? Is it time-capped or unlimited within a window? Unlimited revisions on a fixed-price quote is a red flag — someone will pay for it eventually. |
| Build plan / architecture document | Is it included? If not, ask the price to add it. You need this before you talk to any developer. |
| Coded prototype or working frontend | Be clear about whether you need this. Coded prototypes cost 3-5x more than design prototypes and take longer. Only pay for them if you have a specific reason. |
What the $5,000 range gets you at Deciphering Logic
The Decipher Blueprint is a flat $5,000 engagement. It produces a high-fidelity clickable prototype covering your core user flows, and a written build plan that includes stack recommendations, integration requirements, a rough cost range for the full build, and a sequenced feature roadmap. The $5,000 is credited in full if you move into a build with us.
The reason we structured it this way is straightforward. Founders were coming to us for build quotes without any of the scoping work done, and we were giving them numbers that were either too rough to be useful or too conservative to reflect what they would actually want to build. The Blueprint forces that conversation to happen properly before anyone starts writing code.
You can see an example of the build plan output at decipheringlogic.com/roadmap-sample.
Common mistakes founders make when buying a prototype
- Asking for a prototype but describing a full product, then being surprised by a full-product quote
- Choosing the lowest quote without checking what is excluded — revisions, build plan, and handoff documentation are often stripped out of cheap quotes
- Paying for a coded prototype when a Figma prototype would have served the same purpose at that stage
- Getting a prototype built without a build plan and then having to re-explain the product to a developer from scratch
- Treating the prototype as the deliverable rather than as the first step in a build decision
How long should a prototype take?
For a single-flow, high-fidelity prototype, two weeks is realistic. Three weeks if the product has two distinct user roles or a complex flow that requires multiple rounds of review. Anything quoted at six weeks or more for a prototype — not a build, a prototype — should prompt questions about what is actually included in that timeline.
Our Blueprint runs 14 days. That is a hard constraint, not a target. It forces scope decisions early, which is part of the value.
FAQ
Is a Figma prototype good enough for investor meetings?
For most early-stage pitches, yes. Investors understand that a prototype is a prototype. What matters is whether it communicates the product clearly enough to have a real conversation about the idea. A well-made Figma prototype does that. A poorly scoped coded prototype often does not, and it costs significantly more to produce.
Can I use the prototype to get a developer quote?
You can, and it helps. But a prototype alone is not enough to get a reliable build quote. Developers also need to understand the backend requirements, the integrations, the expected data model, and the non-obvious technical decisions. That is what the build plan covers. A prototype without a build plan will get you a range that is too wide to act on.
What if my product idea changes after the prototype?
It probably will, at least in some ways. That is partly the point — seeing something interactive surfaces assumptions that a slide deck does not. The build plan accounts for this by separating what has to be built in version one from what can wait. Changes to the prototype before a build starts are cheap. Changes after a developer has written three months of code are not.
