Construction estimate — generate one free

Not a blank table — a computed, itemized estimate with real unit costs from a labeled, dated catalog, an honest accuracy class, and a basis of estimate, downloadable free as PDF, Excel, or Word (watermarked on the free tier).

Donnie generates this document from your real project data — computed, not a blank form. Free with an Ask Donnie watermark; your logo on paid plans.

What it is

A professional estimate is more than a total: it's itemized lines (quantity x unit cost for material, labor, and equipment), regional labor adjustment, overhead & profit, and — what most templates skip — an AACE-style accuracy class with a stated range and a basis of estimate covering inclusions, exclusions, and assumptions. Donnie computes all of it deterministically: the same inputs produce the same numbers, byte-identical, every time, with the engine fingerprint printed on the document.

What's on the document

Itemized lines

Item, description, quantity, unit, material, labor (and equipment where it applies), line total.

Markup / overhead & profit

Your percentage, applied transparently — never buried in the unit rates.

AACE accuracy class + range

An honest statement of how developed the estimate is and the range that implies — no false precision.

Basis of estimate

Inclusions, exclusions, and assumptions — what makes an estimate defensible instead of just a number.

Engine fingerprint

The formula version and edit fingerprint printed on the deliverable, so any number can be reproduced later.

Common questions

Where do the prices come from?

A real seed catalog — labeled national averages with as-of dates — plus cited U.S. BLS wage data for regional labor; never a language model inventing numbers. The document states its pricing basis.

Is the free version complete?

Yes — the full document in every format, with an Ask Donnie watermark. Paid tiers put your logo on it instead; the math is identical.
