A building cost estimate lays out what a construction job should cost before anyone commits to it, line by line: materials, labor, subcontractors, permits, overhead, contingency. Contractors send it so the client can see where the money goes, and clients use it to compare bids fairly. This free construction estimate template comes in Word and PDF, with ready-made tables and a signature line where the client accepts.

Is an estimate the same as a quote or a contract?

No, and mixing them up is how disputes start. An estimate is your best projection of cost for a defined scope, broken down so it can be checked. A quote is usually a fixed price for a well-defined job, often short, and it’s what you’d send for a simple product or service; our quote template is built for that. A construction contract is the full agreement for doing the work: schedule, payment milestones, change orders, warranties, and whatever notices your state requires. For that, use our construction contract template.

In practice, the estimate comes first. Say a hypothetical contractor in Tennessee prices a 14 by 20 foot detached garage at $52,900. The client signs the estimate to say “yes, go ahead on these numbers,” and then both sides sign a construction contract that attaches the accepted estimate as the price exhibit. Small jobs sometimes stop at the signed estimate. Anything big, long or expensive deserves the contract too.

What goes on each line of a construction cost estimate?

The template has one table per cost type, which keeps the math honest and makes it easy for a client to ask sensible questions.

Materials. Item, quantity, unit, unit price, line total. “2x6 SPF #2, 8 ft, 140 pcs at $7.35” tells the client far more than “framing lumber, $1,029.” Include delivery if you’ll pay it.

Labor. Your own crew, by task or trade, with hours and rate. If you price labor as a lump sum per task, that’s fine; just be consistent.

Subcontractors. The trades you’ll bring in and the amount you’re carrying for each. If a sub’s number is still a budget figure, say so.

Equipment and site costs. Dumpsters, lifts, portable toilets, temporary fencing.

Permits and fees. Building permit, plan review, inspections, utility fees. Some jurisdictions make contractors spell these out in writing. New York City, for one, requires contractors to tell the customer in writing, before the contract is signed, which permits the work needs.

Overhead and profit, contingency, tax. Show them as their own lines. Hiding markup inside unit prices tends to backfire when a client asks for a change and the numbers don’t line up. A contingency of a stated percentage, with a note on how it’s used, is more believable than a padded total.

Why write down exclusions, allowances and assumptions?

Because the client will assume anything not excluded is included. The template has a short list for each. Exclusions are things you aren’t doing (landscaping, final paint, moving the gas meter). Allowances are dollar placeholders for items the client hasn’t chosen yet, adjusted to actual cost later. Assumptions are what your price depends on: normal soil, no asbestos, the client clearing the garage before demo day.

Three lines here can save you three weeks of arguing later.

How long should the estimate stay valid?

Put a date on it. Material prices move, and your schedule fills up. Thirty days is common for material-heavy work, but choose what you can honestly hold. The template says that after the validity date you can revise the numbers before accepting, and that the price may change if the scope changes.

Why have the client sign an estimate at all?

A signature turns a PDF you emailed into a record that the client saw the scope, the exclusions and the price, and agreed to them. That’s useful even if you never sign a full contract. The template’s acceptance section lets you tick whether signing means “proceed to a formal contract” or “this estimate, with the terms attached, is our agreement.”

A few rules to keep in mind:

Deposits. Consumer agencies warn homeowners against large up-front payments. Connecticut’s consumer protection department advises keeping initial deposits to a third of the project cost, and New York City’s consumer agency tells homeowners to pay no more than 25% up front.
Insurance-claim work. In Florida, contractors working on a property insurance claim must give a good faith, itemized and detailed estimate of the cost of services and materials, under Florida Statutes section 489.147.
Sales at the customer’s home. If the estimate becomes the contract and it’s signed at the client’s home, the FTC’s cooling-off rule may apply; see our roofing contract page for how that works.

How do you fill in the estimate and get it signed?

Walk the site and write the scope first, before any numbers.
Fill each table, then check the totals by hand once.
List exclusions, allowances and assumptions.
Set the validity date and deposit terms.
Send it for signature and keep the signed copy with the job file.

E-signing an estimate is routine. The federal ESIGN Act says a contract or signature can’t be denied legal effect just because it’s electronic; our article on whether electronic signatures are legally binding covers the details.

How the contingency is used: The contingency covers unforeseen conditions within the scope above, such as [hidden rot or damaged framing]. Contractor will tell the Client before using it and will show the amount used on the next invoice. ☐ Unused contingency is not billed. ☐ Other: [describe].

[anything else the price depends on]

If an assumption turns out to be wrong, the price and schedule may need to change through a written change order.

11. Validity and Price Changes

This estimate is valid until the date at the top. After that, Contractor may revise it before the Client accepts. Once accepted, the price changes only through a written change order signed by both parties, or as described in Sections 7 and 8.

13. What Acceptance Means

By signing below, the Client accepts this estimate and authorizes Contractor to proceed as follows (tick one):
☐ Contractor will prepare a written construction contract based on this estimate. No work starts until that contract is signed.
☐ This estimate, including Sections 11 to 14, is the agreement between the parties for this work.

If the Client signs this at the Client's home and the FTC Cooling-Off Rule or a state home solicitation law applies, Contractor will give the Client the required notice of cancellation, and the Client may cancel within the period that law allows.

Quick answers

Is a construction estimate legally binding?

It depends on the wording and what both sides do with it. A document labeled as an estimate reads as a projection of cost, but once the client signs to accept it on stated terms it can become part of a binding agreement. Say in writing which one you intend, as this template does.

How long should a construction estimate be valid?

There's no single rule. Pick a period you can actually hold, often 30 days for material-heavy work, and write the date on the estimate. After that date, you can re-price before the client accepts.

What's the difference between an allowance and a contingency?

An allowance is a placeholder amount for something the client hasn't picked yet, like tile or light fixtures, and it's adjusted to the real cost later. A contingency is a cushion for unknowns in the work itself, such as rot found behind a wall.

Should I charge for writing an estimate?

You can, as long as you tell the customer before you do the work. New York City's consumer agency, for example, says contractors may charge a reasonable fee for an estimate if they disclose it first.
