How this is calculated

The engine sums each line as qty × unitPrice, then applies a discount and tax based on the modes you pick. Modes are independent — you can use per-line discount with aggregate tax, or any other combination.

lineSubtotal  = qty × unitPrice
lineNet       = lineSubtotal − (linePct/100 × lineSubtotal)

quoteSubtotal = Σ lineSubtotal       // always gross (before any discounts)

discount      = aggregate: applyDiscount(subtotal, discountSpec)
              = per-line:  Σ (linePct/100 × lineSubtotal)

taxable       = subtotal − discount  // = Σ lineNet for per-line mode

tax           = aggregate: taxable × rate
              = per-line:  Σ (lineTaxPct/100 × lineNet)
              = inclusive: taxable − taxable / (1 + rate)

total         = inclusive: taxable
              = otherwise: taxable + tax

An amount discount is clamped to the subtotal so the total never goes negative. inclusive tax mode treats line prices as gross — the tax line is the extracted portion, and the headline total equals the taxable base.

Trade preset values are metadata for the printable header only. They never branch the math, which keeps this generator usable for any trade.

Open the estimate / quote builder

The number you write on a construction estimate doesn’t just win the job — once the owner signs, it becomes the basis of the contract sum, and every line is a commitment you’ll be measured against. So the real work of an estimate isn’t the bottom figure; it’s defining what that figure covers. This is a free, no-signup builder you fill in right here: itemize labor, materials, and subcontractors, carry allowances and exclusions, then print or send the bid. Nothing is uploaded, and nothing is stored beyond your browser.

Build it from a takeoff, not a round number

A construction estimate is only as good as the quantities behind it. Work from a takeoff — square footage, linear feet, counts of openings, cubic yards — and turn each into a line with its own quantity and unit price rather than one lump sum. The builder gives you a description, quantity, and unit-price cell per row and totals them as you go, so framing labor, lumber, concrete, and each finish read as separate lines a client (or a lender) can actually follow. Group your rows the way you’ll manage the job: labor categories, then materials, then subs. A line item you can defend with a quantity is a line item you can stand behind when the bid is questioned.

Allowances hold the budget for decisions not yet made

On most builds the owner hasn’t picked everything when you bid — flooring, fixtures, countertops, appliances. Rather than guess high and lose the job or guess low and eat the gap, carry an allowance: a line with your budgeted dollar figure and a description that says, plainly, this is an allowance to be reconciled against the actual selected cost. The builder treats it like any other line in the subtotal. When the owner chooses something above or below the allowance, the difference becomes a change order — a clean adjustment instead of an argument over what you “should have included.”

Exclusions are the line that protects your number

What a construction estimate leaves out matters as much as what it includes. Use the terms and notes field to list exclusions explicitly: permit and inspection fees if the owner pulls them, hazardous-material abatement, unforeseen subsurface or concealed conditions, surveying, owner-supplied materials, and any scope belonging to other trades. Spelling these out doesn’t weaken the bid — it caps the open-ended liability that otherwise hides inside a tidy total. A reader who sees a clear exclusion list trusts the rest of the number more, not less.

Carry subs, markup, and a contingency you can stand behind

Self-performed work and subcontracted work both belong on the estimate, but keep them legible: enter each sub’s scope as its own line at the price they quoted you, with your markup built into the rate or shown as a separate line, whichever your client expects. The builder’s discount and tax controls are yours to set — the tax cell starts at 0% because construction tax treatment varies widely by jurisdiction and by whether labor, materials, or both are taxed, so enter your own local rate and it applies to the post-discount subtotal. If you carry a contingency for unknowns, add it as a labeled line so it’s visible rather than buried; a contingency the client can see is one they’re far likelier to accept. To pressure-test your material pricing before it lands on the bid, the parts & material markup calculator turns cost into a consistent, defensible sell price.

From accepted bid to signed work — and the changes after

A construction estimate has a shelf life. Material prices move, and sub quotes expire, so set the valid-until date honestly and let it do its job: it tells the owner the number is good through a date, not forever. When the bid is accepted, it becomes the baseline for the contract and the construction work order that authorizes the crew. From there, every added or substituted scope rides on a change order that adjusts the contract sum in writing before the work happens — that’s how the baseline moves without a fight at closeout. When it’s time to bill against the accepted scope, the service invoice template carries the same line items forward. This page builds the bid before the job, not the bill after it — a document you own, fill in, and hand off, with no account and no stored ledger behind it.

Frequently asked questions

What's the difference between a construction estimate and a contractor's quote?

Scope and depth. A simpler contractor estimate is a client-facing number meant to be read, approved, and signed quickly. A full construction estimate is the detailed bid underneath it — every labor category, material quantity, and subcontractor priced as its own line, with allowances and exclusions spelled out. It's the document that becomes the basis of the contract sum, so it carries far more than a single price.

How do I handle allowances for items the owner hasn't picked yet?

Enter the allowance as its own line item with a quantity and a unit price that reflect your budgeted figure — for example a flooring or fixture allowance — and note in the description that it's an allowance to be reconciled against actual selected cost. The builder totals it like any other line. When the owner makes a final selection, the difference becomes a change order rather than a surprise you absorb.

What should I exclude from a construction estimate?

Anything you can't price with confidence at bid time: permit and inspection fees if the owner pulls them, hazardous-material abatement, unforeseen subsurface or concealed conditions, owner-supplied materials, and work by other trades outside your scope. List exclusions in the terms/notes field. Exclusions don't make the bid look weaker — they're the line that keeps the contract sum from quietly absorbing risk you never priced.

Once the owner accepts the estimate, is that the final price?

The accepted estimate sets the starting contract sum, but construction work changes. Any added scope, substituted material, or condition you excluded gets priced separately on a change order that adjusts the sum in writing before the work proceeds. The estimate is the baseline; the change orders are how that baseline moves without disputes at the end.
