Free tools for interior designers
Calculators for the part of the business nobody teaches: what to charge, what a markup actually earns, and what your software bill does when the team grows. Every one of them runs in your browser — no email, no account, nothing stored.
- Free toolInterior design fee calculator: the same project, billed six waysPut in your hours, rate and furnishings budget and see what the same project bills under hourly, flat fee, cost-plus, hourly-plus-markup, retail and percentage-of-project — with the effective hourly rate for each.
- Free toolFurniture markup calculator: list price to what the client owesEnter list price, trade discount, freight and receiving, and see your net cost, client price, gross profit and — the number most people get wrong — your actual gross margin. Includes chained discounts and a target-margin solver.
- Free toolInterior design software cost calculator: what your team size really costsMove 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.
Why these are ungated
Because a calculator behind an email form is an advertisement, and nobody links to an advertisement. These exist to be useful on their own — and if you want the same maths applied to real projects, with the proposals, purchase orders and approvals attached to it, that is what NYA is.
