Cost to Build a 3D Room Planner App: 2026 Guide

You have decided your product needs a room planner. A customer should be able to lay out a room, drop in furniture, see it in 3D and save the result. Now you are trying to price it, and every guide gives a different figure, from a few thousand dollars to a quarter of a million. The gap is not because anyone is lying. It is because most of them are quietly pricing two different products as one.

This guide separates the two. There is the planner, the layout engine, the 2D and 3D editor, the catalogue and the save and share flow. Then there is the AR and room scan layer, the camera placement and the scanning that most articles fold into the same number. Keep them apart and the 3d room planner cost stops being a mystery and becomes a set of choices you control.

What does a 3D room planner app actually cost to build?

It costs whatever its scope costs, and scope has three big dials: how deep the catalogue is, how many platforms you ship on, and whether you add AR room scanning. Appico's published starting points are an MVP from $10,000, a mobile app from $12,000, a website from $1,000, and larger builds up to about $150,000, with maintenance charged as a separate monthly plan.

Those are starting points, not a ceiling and not a single quote. A room planner is more than a standard app because it carries a live 3D editor and a catalogue of models, so it usually sits above a plain mobile app of the same size. If you want to sanity check a number quickly, our app cost calculator gives a rough band from a few inputs. For the wider question of how build cost is put together, our guide on what a web app costs to build covers the same drivers in general terms.

If your real goal is a full shopping experience like the big furniture apps, read the pillar guide on how to build an app like IKEA Place, then come back here to price the planner part on its own.

What are you paying for in a room planner app?

You are paying for four core parts: a layout engine that understands rooms and walls, an editor that shows the same space in 2D and 3D, a catalogue of 3D products the user can place, and a way to save, reopen and share a plan. None of these needs a camera. This is the planner, and it is the part every room planner app must have.

The layout engine is the quiet one. It has to hold room shapes, let a user draw or adjust walls, snap furniture to sensible positions, handle undo, and keep a 2D floor plan and a 3D view showing the same truth at the same time. That last point sounds small and is not. When a user drags a sofa in the 3D view, the 2D plan has to move with it, to the centimetre, every time. Getting that sync right is real engineering, and it is why a planner costs more than a list based app of the same size.

What drives the cost of a 3D room planner app?

Six things drive the cost: the depth of the 3D catalogue, the real time editor, keeping the 2D and 3D views in sync, the save and share system, the number of platforms, and the optional AR scan module. The catalogue and the editor take the largest share. AR scanning, when you add it, is a separate line rather than a small extra.

Here is the same picture as a figure. It shows where a budget grows once the work starts, which is rarely where a first time buyer expects.

Two of these deserve a warning. The catalogue looks cheap when you scope it with ten products and expensive when you realise a real store has hundreds. And cross platform reach is not one build stretched across three screens. iOS, Android and web are three builds that share design and logic but need their own work, so each platform you add is another real cost, not a rounding difference.

Planner cost or AR cost? The line most guides blur

The single biggest reason room planner estimates disagree is that most of them price AR room scanning as if it were part of the base planner. It is not. A planner lets a user lay out a room on a screen. AR lets a user point a phone at their actual room, place furniture through the camera at real scale, and scan the space. That AR layer is a separate module with its own cost, its own device limits and its own engineering.

The figure below splits the two so you can decide what your first version really needs.

The device reality is what makes AR its own cost. On iPhone and iPad, Apple's room scanning tool RoomPlan uses the camera and LiDAR Scanner to create a 3D floor plan of a room and exports it in USD or USDZ, but it only runs on the newer devices that carry a LiDAR Scanner. On Android, Google's ARCore Depth API creates depth from motion and works without a dedicated depth sensor, but it still needs a capable device and careful tuning. Supporting both, and the phones that have neither, is engineering you pay for once you commit to AR.

So the honest sequence for many products is: build the planner first, then decide on AR. If you do want the camera side, price it properly against our guide on the cost to build an AR furniture app, and settle the platform question with whether you actually need LiDAR and the trade offs in ARKit versus ARCore. Each of those is a real fork in the cost.

The catalogue is the real mountain

The part almost every cost guide skips is the 3D product catalogue, and it is where the largest, most surprising money goes. A room planner is only as good as the products a user can place in it, and every one of those products needs a real 3D model, not a photo. Ten models is a small job. A catalogue that matches a real store is an operation that runs for as long as the product range changes.

Each model has to be built or captured, cleaned up, optimised so it renders fast on a phone, exported in the right formats, and kept under a tight file size so it loads over mobile data. That usually means a model exported twice, once as GLB for Android and web and once as USDZ for Apple, which is covered in our explainer on USDZ and glTF formats. The pipeline for making the models sits in how to make 3D models for a furniture app, and doing it for hundreds of products without it eating your team is the subject of building a 3D catalogue at scale.

The point for pricing is simple. Ask any quote how many models are included, who makes new ones, and what each extra model costs. A planner with a beautiful editor and an empty catalogue is a demo, not a product.

How the build splits into phases

A room planner build usually runs in five phases: discovery and design, the planner core, the catalogue, extra platforms, and then AR if you want it, with maintenance running after launch. Pricing per phase, rather than as one lump, lets you stop after any phase with something that works and earns, instead of paying for everything before you learn anything.

1. Discovery and design. Scope, user flows and the look of the editor. Cheap relative to the rest, and the phase that saves the most money later by cutting features you do not need.
2. The planner core. The layout engine, the 2D and 3D editor, and the save and share flow. This is your MVP, and where an MVP from $10,000 or a mobile app from $12,000 sits.
3. The catalogue. Your first set of 3D models, the tools to add more, and the format and size work. The biggest variable, driven by how many products you start with.
4. Extra platforms. A second mobile platform or a web version. A web planner starts from website work at $1,000, though a full web app costs more than a simple site.
5. AR and room scan. The optional camera module, added only when the core and catalogue prove the product. This is where a large scope can climb toward about $150,000.

For a deeper walk through the engineering of each phase, our companion guide on how to build a 3D room planner app covers the technical choices behind these numbers.

What appico charges to build a room planner app

Appico prices to a fixed scope, so a quote is one number for an agreed set of features, not an hourly meter that surprises you at the end. The table maps the common cost items to what drives each one and to our published starting point, so you can see where your money goes before you commit. Every figure here is a starting price, and the only prices appico publishes.

Read the table as a menu, not a bill. Most first products take the top three rows, the layout engine, the catalogue and the save and share system, and leave AR and extra platforms for later. That is the version that gets to real users fastest. You can see the full range of what we build on the app development service page, and we quote the exact scope after one conversation about your catalogue and your platforms.

Does building in India change the cost?

Yes, and this is where the market reality matters. Senior engineering time in the US, UK or Australia is priced far higher than the same senior time in India. The same room planner scope, built by a good India team, usually costs less than a comparable US or UK agency for work of the same standard. That gap is real and it is the honest reason offshore build cost is lower.

The catch is that a room planner is not ordinary app work. It needs people who have shipped 3D and AR, tuned a catalogue pipeline, and made a 3D editor feel smooth on a mid range phone. A cheap team that has not done this before will cost more in the end, because the 3D pipeline and the editor are exactly where inexperienced work falls apart. The saving is only real when the lower rate sits under a team that has built the hard part before. Appico is a US and UK facing brand with a senior India build team, and clients own the source code, the models and the accounts from day one.

When a 3D room planner app is not worth building

A room planner is not always the right spend. It is not worth building when your product range is tiny, when a few good photos would do the job, when your buyers are not the kind to plan a room on a phone, or when you cannot commit to keeping the 3D catalogue current. In those cases the money buys a feature nobody uses and a catalogue that goes stale.

Be honest about the catalogue commitment above all. A planner with ten models when your store sells four hundred products is worse than no planner, because it sets an expectation you then break. If you cannot resource new models as your range changes, do not start. And if the plan is really to make money from the planner itself rather than to sell furniture, read how room planner apps make money first, because the answer shapes how much you should sensibly spend.

There is also a timing question. If you have not validated that customers want this at all, a full 3D build is the wrong first step. Our guide on turning an idea into an app covers the cheaper ways to test demand before you fund a catalogue and an editor.

Our take

Price the planner, then decide on AR. The layout engine, the editor and the catalogue are the product, and they are where an honest budget goes. Camera placement and room scanning are a real add on with real device limits, not a free extra to sprinkle on top, so they deserve their own line and their own decision. The teams that overspend are the ones who bought the whole picture at once. The teams that ship are the ones who built the core, filled a small catalogue, put it in front of users, and grew from there.

If you want a fixed scope number for your exact catalogue and platforms, tell us what you sell and where your buyers are, and we will map it to a build. You can start on the appico app development page. Bring your product range. The size of that catalogue is the first thing that decides the price.
