How to write a kitchen remodel estimate

Kitchen remodel estimates fail contractors in two places. The first is the allowances side: placeholders set too low for cabinets or countertops the customer hasn't picked yet. The second is trade coordination: underestimating how long plumbing rough-in, electrical, or cabinet installation takes when multiple crews sequence through the same space. This guide gives you a line-item framework for building a kitchen estimate from the ground up — one that holds when the homeowner upgrades the countertop selection mid-project or your electrician finds knob-and-tube wiring behind the walls.

What a kitchen remodel estimate should include

A complete kitchen estimate breaks work into every phase and trade. Handing a client a single lump-sum number without itemization puts you at a disadvantage the moment they push back on price or want to cut scope. For more on when to use lump-sum versus line-by-line proposals, see our breakdown of lump-sum vs. itemized quotes for remodeling contractors.

Here are the line items every kitchen estimate should carry:

1. Demo and haul-away. Removing old cabinets, countertops, flooring, and appliances. Price dumpster rental or debris disposal separately — discovering what's behind a 40-year-old kitchen wall is where your contingency earns its keep.

2. Cabinet procurement and installation. This is almost always the largest single line item. According to the National Kitchen & Bath Association's 2024 Kitchen and Bath Market Outlook, cabinets account for 29% of the average kitchen remodel budget. If the homeowner hasn't selected cabinets yet, use an allowance placeholder — see the next section on how to set it correctly.

3. Countertops. Material, templating, and installation labor. This is almost always an allowance until the homeowner finalizes a surface selection.

4. Plumbing rough-in and finish. Drain adjustments, supply line rough-in, and finish connections for the sink, dishwasher, and ice maker. The U.S. Bureau of Labor Statistics reports a national median hourly wage of $34.70 for plumbers and pipefitters per the May 2025 Occupational Employment and Wage Statistics release. A typical kitchen plumbing rough-in and finish runs 8–16 hours, more if the layout shifts significantly.

5. Electrical rough-in and finish. Dedicated circuits for the dishwasher, microwave, and refrigerator; kitchen island outlets; under-cabinet lighting; and exhaust hood wiring. The same BLS release puts the median at $34.37/hr for electricians. Budget 10–20 hours for a mid-range kitchen electrical.

6. Flooring. If the remodel includes the kitchen floor, list demo, subfloor prep, material, and installation as separate lines — they have different labor rates and different failure modes.

7. Backsplash tile. Often underestimated. Backsplash tile labor runs slower per square foot than floor tile because of precision cuts around outlets, switches, and the underside of upper cabinets.

8. Painting and drywall. New cabinets almost always expose where old ones met the wall, requiring patching before paint. Budget a full paint job including ceiling.

9. Appliance installation. List installation labor as a separate line from the appliance purchase. The purchase price is typically a homeowner allowance; you set the connection labor.

10. Permit fees. Add a handling charge on top of your actual permit cost. Pulling the permit is your responsibility and your liability — price it that way.

11. Contingency. Pre-1980 homes routinely surface corroded supply lines, outdated wiring, or undersized venting. Budget 15–20% contingency on full gut remodels and 10% on cosmetic refreshes.

12. Overhead and profit. Applied after contingency, as a percentage of total job cost. Name this line explicitly — don't hide it in other line items.

How allowances work — and why they matter more on kitchens than any other job

An allowance is a budget placeholder for a finish item the homeowner hasn't selected yet. It appears on your estimate like this: "Cabinet allowance — $12,000. Owner to select within this budget; amounts above the allowance are documented as change orders at time of selection."

Kitchen estimates require more allowances than any other residential job because the three most expensive categories — cabinets (29% of budget per NKBA), countertops, and appliances — are almost never finalized before the contractor is asked to provide a number. Homeowners want a price before they've visited a single showroom.

The trap is setting the allowance too low to look competitive. A $6,000 cabinet allowance on a kitchen that realistically needs $14,000 of cabinets isn't a lower bid — it's a bigger change order three months into the project, after the homeowner has already mentally spent their savings on other things. Set allowances at realistic midpoints for your market. Here's a reasonable tier guide:

Document in writing that any selection above the allowance triggers a signed change order before the order is placed. Don't let the homeowner call the cabinet company directly — all selections should route through you so you control the paper trail.

Setting your markup on a kitchen remodel

Kitchen remodels have high materials exposure. Getting markup right matters more on a $50,000 job than on a $3,500 service call. Use the markup calculator at /tools/markup-calculator to run your actual numbers, but here's the layered framework:

On your own labor: Price at your fully loaded rate — what it actually costs you per hour in the field, including labor burden (taxes, benefits, insurance), not just the wage you pay your crew.

On subcontracted labor: Mark up sub labor 10–20% for GC coordination, scheduling, and warranty risk. If a sub disappears mid-tile job, it's your problem to solve for the homeowner. Price the risk accordingly.

On materials: Remodeling contractors typically apply a 25–40% markup on materials. Lock your material prices to the estimate for a set period (30–45 days is standard) and include a clause that prices are subject to revision if the project start slips significantly — lumber, tile, and cabinet pricing can shift in a quarter.

Overhead and profit: After labor and materials with markup, apply your overhead-and-profit percentage as a named line. For residential remodeling, this typically runs 15–25% of total job cost depending on your market and project complexity.

One note for client conversations: according to Zonda's 2025 Cost vs. Value Report, a minor kitchen remodel in the $28,000 range returns approximately 113% of its cost nationally at resale — meaning a well-scoped kitchen update adds more value than it costs. That's a concrete talking point when a homeowner starts negotiating on price.

How to handle change orders on a kitchen remodel

Change orders are routine on kitchen remodels, not exceptions. The homeowner upgrades from quartz to slab marble after seeing it in the showroom. The plumber finds galvanized supply lines that need full replacement. The cabinet order comes in two inches narrow because the space was measured off one framing stud.

The framework is simple: every deviation from the signed estimate — up or down — gets a written change order signed before work proceeds. Our guide on how to write a change order for contractors covers the exact format, including what to do when a homeowner approves verbally but won't sign before the sub is already on-site.

Kitchen-specific change order triggers to plan for:

• Allowance overages. Customer selects above the cabinet, countertop, or appliance allowance. This should be automatic — document it at time of selection, not after the material is delivered.
• Hidden conditions. Soft subfloor under existing tile, corroded drain connections behind a wall, or outdated panel capacity discovered during rough-in.
• Scope additions. "While you're at it" requests — moving the island, adding a pot filler, converting a window to a pass-through. These are real work. Price them.
• Material delays. If lead times push the start date and material costs rise in the interim, a change order protecting your margin is appropriate and defensible.

Set the expectation at estimate delivery, not after the first surprise. Walk the homeowner through the change order process before they sign the contract, and put it in writing that verbal approvals from them must be followed by a signed document before work proceeds.

Takeaways

• Break every kitchen estimate into trade buckets before you write a number — cabinets, countertops, plumbing, electrical, flooring, backsplash, paint, and permits as distinct line items
• Cabinets account for 29% of the average kitchen remodel budget per NKBA — an underestimated cabinet allowance throws off your entire estimate
• Set allowances at realistic market midpoints; a low allowance isn't a competitive bid, it's a change order waiting to happen
• Apply markup in layers: loaded labor rate first, sub coordination markup second, materials markup third, overhead-and-profit line last
• A signed change order process stops scope creep before it starts — walk the homeowner through it at contract signing, not after the first surprise

Build faster kitchen estimates, win more jobs

A line-item kitchen estimate takes more time upfront than a napkin number, but it pays for itself every time a client tries to "trim 10%" or a hidden condition hits mid-project. JobEstimator is built for multi-phase, multi-trade estimates exactly like kitchen remodels: enter your trade rates, apply markup by category, and produce a clean proposal the homeowner can read and approve in one sitting. Plans start at $39/mo with no per-quote fee. If you're also quoting bathrooms, our walkthrough on how to quote a bathroom remodel covers the same allowance and change-order framework with the trade sequencing specific to that scope.
