Remodel Cost Calculator for Kitchen & Bath

The form your customers fill out

A live calculator, not a static quote request. Your customer enters their details and watches the number update on the spot, which is what turns a browser into a booked job.

What it calculates

Kitchen or bath priced by size and finish tier from your line-item sheet
Cabinets, countertops, tile, and fixtures pulled from selection tables
Layout changes and moving plumbing added as conditional cost drivers
Demo, permits, and labor rolled in with your margin kept internal
Homeowner lead with the estimate already calculated lands in your dashboard

Why it closes more deals

⚡

A live number closes deals

Customers who see a real estimate the second they enter their details are far likelier to book than ones told to call for a quote. The number is the hook.

📊

Runs your most complex spreadsheet

Multi-tab workbooks, lookup tables, tiered rates, conditional line items, the lot. If the math runs in Excel, CalcForms runs it behind a clean form.

🔁

Update it by chatting

Prices move. Ask Claude to change a rate, add an option, or insert a step and the live form updates in seconds. No developer, no redeploy.

🎯

Backtest before you publish

Run your last 20 real jobs through it and tune the formula until the live estimate matches what you actually charge. Ship it once it lines up.

How this form was built

No template builder and no code. One message to Claude with the CalcForms connector switched on:

✦ Claude with the CalcForms connector

Build a kitchen and bath remodel cost calculator. Inputs: room (kitchen base $250/sqft, full bath $325/sqft, half bath $200/sqft), room size, finish level (standard 1.0x, mid-grade 1.4x, high-end 1.9x), layout change (keep 1.0x, minor 1.15x, move plumbing/walls 1.35x), and cabinet choice as an add-on. Multiply sqft by the room rate, apply the finish and layout multipliers, add cabinets, then show the homeowner a low-to-high range at minus 10% and plus 15%. Keep my line-item costs and margin internal.

Done. I built Remodel Cost Calculator with your pricing and deployed it to forms.badabingapp.cc. The math runs server-side and every submission is saved with the inputs and email. Want to add a field or change a rate? Just tell me.

"Build a kitchen and bath remodel cost calculator.

Example run: A 180 sq ft kitchen ($250/sqft) at mid-grade finish (1.4x) with minor layout changes (1.15x) returns a homeowner-facing range of about $65,000 to $84,000.

FAQ

Does my multi-tab estimating workbook come across?

Yes. A workbook with separate tabs for cabinets, countertops, tile, and labor feeding a summary stays intact, with the IF and VLOOKUP logic preserved.

Can it price standard versus high-end finishes?

Yes. Each finish level applies its own multiplier and selections like cabinets and countertops pull from lookup tables, so the estimate moves with the choices.

Does the homeowner see my line-item costs?

No. They see the estimate range only. Your cabinet, labor, and material costs stay internal, chosen per field.

Can I check it against remodels I have done?

Yes. Backtest it against your past kitchens and baths and tune the rates until the estimate matches what those jobs actually came in at.
