Contractor Estimate Calculator | General Construction Bid Spreadsheet | Materials Labor Markup Tax | Excel + Google Sheets Template

A real estimate spreadsheet that handles materials, labor, markup,
overhead, and tax — and prints a client-ready quote at the end.

If you bid jobs on the back of an envelope, you're either leaving
margin on the table or eating the cost when materials come in over.
If you bid in QuickBooks, you spend more time fighting the software
than measuring the job. There's a middle ground: a spreadsheet that
does the math right and gets out of your way.

This is the general-trade version — same engine as our flooring
calculator, but built for any contractor: painting, tile, drywall,
decks, framing, remodels, anything where you need materials + labor
+ markup + tax to add up correctly and land in front of a client.

WHAT'S INCLUDED
✓ Excel (.xlsx) workbook — works in Excel 2016 and newer, LibreOffice
✓ Google Sheets version — delivered as PDF with a "make a copy" link
✓ 5 working tabs:
– Instructions & color-coding key + disclaimers
– Materials — generic line-item table (Material 1, 2, 3…) with
unit price + quantity + supplier markup %
– Labor — per-hour OR per-unit pricing, demo line, prep line
– Estimate Summary — Materials + Labor + Overhead % + Profit
Markup % + Sales Tax % → Grand Total, in the correct stack order
– Client-Facing Quote — print-ready one-page estimate with your
logo placeholder, client info, scope summary, payment terms
✓ Color-coded input cells (yellow) — type only where the sheet asks
✓ Locked headers, protected formulas — can't accidentally break it
✓ Formula constraints stay basic: SUM, ROUNDUP, IF, data validation.
Older Excel won't break; no LET/FILTER/UNIQUE/dynamic arrays.

WHAT YOU GET BACK
- A repeatable bid process that doesn't depend on remembering what
you charged the last guy
- Markup applied to cost (not to retail), tax applied on subtotal
(not on tax) — the correct stack order most spreadsheets get
backwards
- A client estimate PDF you can email same-day instead of "I'll get
you a number tomorrow" (which is where jobs get lost)
- Same back-office math whether you're bidding a $2K paint job or
a $40K remodel

WHO THIS IS FOR
- Painting contractors, tile setters, drywallers, deck builders,
remodelers, handymen — any trade that bids material + labor jobs
- Solo owners and small crew leads doing their own estimating
- Anyone who tried estimating software, hated paying $50–$100/mo,
and went back to spreadsheets

WHAT THIS IS NOT
This is the general-trade version (no flooring-specific waste factor
or box-coverage logic). If you specifically install flooring, see
the Flooring Estimate Calculator Pro for sq-ft, waste-factor
dropdowns, and box-rounding math built in.

BUILT BY OPERATORS WHO RESEARCHED THE WORK
We built this against how contractor estimates actually get
assembled — material runs, labor on units OR hours, overhead carried
in markup, tax on the subtotal. The stack order matches what an
estimator's spreadsheet should produce, not what a generic small-
business template defaults to.
