Where do these prices come from?

Each vendor's own published pricing page, re-checked by a script in this repository and dated at the top of the page. Where a vendor publishes no price for a tier — Houzz Pro does not publish one for any paid tier — the table says so rather than repeating a figure from an aggregator.

Does the calculator include add-ons?

No — it compares base subscriptions plus per-seat charges only. Advertising packages, payment processing fees and paid onboarding are real costs and are covered on the individual vendor pages rather than folded into a single number here.

What counts as a seat?

That is vendor-specific and worth checking against your actual team. Some platforms count only staff logins, while bookkeepers, contractors and clients may be free collaborators or may not. On a flat-rate plan the question does not arise, which is part of the point.

Interior design software cost calculator: what your team size really costs

Move the team-size slider and see what seven interior design platforms cost per month and per year at that headcount, computed from each vendor's own published rate and dated.

By Idan Mann, founder of NYA

The short answer

Set your team size and this calculator shows the monthly and annual cost of seven interior design platforms at that headcount, computed from each vendor's published rate. Per-seat pricing is what makes the curves diverge: adding a fifth person costs nothing on a flat plan and hundreds per year on a per-user one.

All competitor prices on this page were taken from the vendor's own pricing page on July 31, 2026 and are linked at the bottom. Prices change — tell us if you spot one that has.

Software pricing pages quote the price of one seat, which is the number that flatters them. The question a studio actually has is what the bill looks like when the team is five people — and that is a different comparison, because half of this category charges per user and half does not.

Software	Monthly at 3 seats	Per year	Model

Computed from each vendor's published rates — sources and verification dates are listed at the bottom of this page. Houzz Pro publishes no base subscription price, so only its $60-per-extra-seat add-on can be computed.

Why the lines diverge so fast

A per-seat plan is a multiplication and a flat plan is a constant. At one seat the difference is a rounding error; by five it is the largest recurring software line in a small studio's budget. Nothing changes about the product between those two points — only the billing model.

Per user, where every head multiplies the whole subscription — the steepest curve in the table.
Base plus seat, where a platform fee covers the first user and each additional one carries an add-on. Most of this category prices this way.
Flat per firm, where headcount does not appear in the bill at all. That is how NYA is priced: $49 solo, $129 for up to five, $299 unlimited.
Quote-gated, where no price is published for any tier — see Houzz Pro pricing for what its own pages do and do not state.

Per-seat pricing has a second cost that never appears on an invoice: it makes you ration access. Studios on per-user plans routinely keep a bookkeeper, a junior or a contractor out of the system to avoid another seat — and the workarounds that follow are spreadsheets, which is where the data drifts.

Reading the annual column

The yearly figures are the monthly rate times twelve, which is the honest comparison when several vendors quote an annual-billing rate on their pricing page and bill a higher one month to month. Programa is the clearest case: the figures above are its annual rate, and month-to-month it is meaningfully higher. Our pricing guide works through each vendor's billing rules in full.

Cost is not the only axis, and we say so on every comparison we publish: Studio Designer is the stronger choice if you need double-entry accounting inside the platform, and Houzz Pro is the stronger choice if what you are buying is lead generation. This calculator prices the software — it does not tell you which one fits.
