What you can do with the Interior Design Cost Estimator
Totals are calculated in whole paise, so they always add up exactly: material and labour separately, wastage, discounts, GST and the project total, with each room’s breakdown.
Room-wise and project totals
Each room’s subtotal and the whole project, material and labour shown separately.
Quantities from room sizes
Floor area, wall area and perimeter calculated from length, width and height — or override them.
Wastage, discounts and GST
Per-line wastage and discount, tax-inclusive or exclusive rates, CGST/SGST or IGST.
Estimated or actual
Mark lines as estimated or actual so everyone knows which figures are final.

Frequently asked questions
Is it free?
Yes. Creating, editing and downloading PDF, PNG and JPG files is free, with no watermark and no subscription.
Are market rates included?
No. Sample rates only show how it works; enter your own.
How are totals rounded?
Each line is calculated in whole paise (or cents) and the totals are the exact sum of the lines, so nothing drifts by a rupee.
Can I keep everything for one client together?
Yes. Create an interior project for the client and link moodboards, plans, material boards, estimates, proposals, presentations and invoices to it. The project dashboard shows them all, with the room list and budget summary.
Do I need an account?
No. Guests can create and download straight away; guest work is kept for a limited time after the last visit. A free account keeps projects and your material library permanently.
