Why Are Kitchen Remodel Quotes So Different?

Start with the fact that two of those three companies are not the same kind of company. A design-build firm carries a designer, a showroom, and a project manager on payroll. The general contractor with a truck and twenty years of subcontractors on speed dial carries none of that. Both can build your kitchen. They cannot charge the same number for it, and neither of them will open the conversation by explaining why.

So take the three bids apart in the order that actually matters. That order is not the order they are printed in, and the total is the last thing you should look at.

The gap is usually the allowance

An allowance moves more of the gap between two kitchen bids than any other single line on them, and most homeowners meet their first one buried inside a change order.

An allowance is a placeholder. It is a dollar figure the contractor writes into the bid for something you have not chosen yet. Countertops. Tile. Cabinet hardware. Lighting. Appliances. It looks like a price. It is a guess with your name on it.

A bid can read "Countertop allowance: $3,000" and total $52,000. Another can read "Countertop allowance: $9,000" and total $58,000. Those two kitchens are the same kitchen. The $6,000 difference is not workmanship, scope, or greed. It is one estimator assuming you will pick laminate and the other assuming you will pick quartz.

How a low allowance turns into a bigger bill

Set the allowance low and the headline number wins the job. Then you go to the slab yard. You fall in love with the quartz, because everybody does. The allowance was $3,000 and the quartz is $9,000, so $6,000 lands back on your invoice as an overage.

Two details make this worse than it sounds, and neither is obvious from the bid.

• A material allowance usually buys the material and stops there. Installation labor, fabrication, and delivery were priced elsewhere in the contract, calculated against the cheap slab the estimator was picturing.
• The overage is often marked up. You do not always pay the $6,000 difference. You pay the difference plus the contractor’s margin on it.

By the time you find out, demo is done, your sink is in the garage, and you are washing dishes in the bathtub. That is the worst possible moment to discover your negotiating position.

An allowance is not a contingency

Homeowners run these together and contractors rarely stop them. The tile you have not picked yet is an allowance: the thing exists, the price does not. The rot behind the dishwasher is a contingency: nobody knew it was there at all.

Two problems, two pots of money, and a bid can fund the first while ignoring the second entirely. When that happens, whatever the demo crew uncovers on day two comes out of your pocket instead of a reserve somebody planned for. Both belong in writing, which is one more reason the kitchen remodel contract carries more weight than the bid it grew out of.

Two bids can be pricing two different kitchens

The industry sorts kitchen work into tiers, and the tiers sit far apart. Zonda’s 2025 Cost vs. Value report prices the same defined projects across 119 US markets, and every one of its kitchen figures describes the same benchmark room: a 200 square foot kitchen with 30 linear feet of cabinetry, averaged nationally. A midrange minor remodel comes in at $28,458. A midrange major lands at $82,793. Go upscale on the major and it is $164,104.

That is a ladder of scope. It is not a quote for anybody’s kitchen, including yours. Your number climbs above the ladder with a bigger room, a high cost metro, plumbing that has to move, or anything structural. It falls below with a small galley, a cheap metro, and a layout you leave exactly where it sits.

The word doing the work there is "minor," and it does not mean what most people assume. In that report a minor remodel leaves the cabinet boxes in place and refaces them with new shaker style fronts, new drawer fronts and new hardware. It also swaps in a new energy efficient range and refrigerator, a midpriced sink and faucet, new laminate countertops and new resilient flooring. Appliances are inside that scope. The layout is what stays put.

The major is a different animal. It pulls the cabinets out and replaces them outright, then rebuilds the room around the new boxes. What it does not promise is a new floor plan. The midrange major scope keeps a functional layout, so a bigger total is not proof by itself that anyone is relocating your sink.

So when a $38,000 bid sits next to a $104,000 bid, check whether one of them quietly quoted you a refacing job. Ask each bidder straight out whether the cabinet boxes are staying, because refacing is a real product and a homeowner asking for "a new kitchen" will often accept a price on one without ever noticing the boxes never left.

One number from that same report is worth holding onto. The $28,458 minor remodel is credited with $32,141 of added resale value, about 113% of what it cost. The midrange major is credited with roughly 51%, the upscale major about 36%. Spending more on a kitchen does not bring more back. Proportionally it brings back less at every rung.

Now the part nobody quotes with it. That 113% is not a record of anything that sold. Zonda builds the resale side by surveying more than 6,000 Realtors and asking each of them what value a given project adds to a home’s sale price. The cost side is not a stack of real invoices either. It is modeled from federal government price indexes and a professional estimating program. Read 113% as a careful poll of what people who sell houses believe, priced against software. It is the best national yardstick anybody publishes and it is still professional judgment on both ends, not money that changed hands.

What is the most expensive part of a kitchen remodel?

Cabinets, nearly always. So if you want to know why one bid runs $20,000 heavier, start there and work outward. NKBA’s market research puts US kitchen cabinetry at roughly $20 billion a year against about $80 billion of total spending on kitchen products. Call it about a quarter of everything bought for the room, before a single hour of labor gets billed.

Treat any figure more precise than that with suspicion, including the ones you will see quoted to the decimal. The underlying reports sit behind paywalls that run into the thousands of dollars, and the sources do not agree on whether "kitchen spending" includes installation at all. The ranking is the durable fact: cabinets lead, countertops usually come second. Your own cabinet share climbs with a big room, a custom tier, and a full box replacement. It drops if you reface, if the room is a small galley, or if a runaway appliance package eats the budget.

Showrooms sort cabinets into three tiers, and the tier changes the price, the lead time, and the schedule risk all at once. Know that the three tiers are a sales convention, not a standard anybody enforces. The one real standard is ANSI/KCMA A161.1, and it grades performance: a wall cabinet loaded to 600 pounds, a door cycled through 25,000 swings. It has nothing to say about which tier a cabinet belongs to.

• Stock: made in fixed sizes and sitting in a warehouse. Cheapest, often on the shelf or a couple of weeks out. You fill the leftover wall space with filler strips.
• Semi-custom: stock sizes with real modifications, like a shortened depth or a different door. Typically a month or two out.
• Custom: built to your room’s measurements. Longest lead time by far, often a couple of months or more, and the box is built to the wall rather than shimmed to fit it.

Notice what is not in those bullets: what the box is made of. Material follows the tier loosely and nothing more. Particleboard is common at the stock end and plywood turns up more often as you move up, but no standard requires either one, and A161.1 measures what a cabinet survives rather than what it is built from. Particleboard boxes pass it. So ask what the box is made of. Do not read it off the tier.

Per linear foot, published ranges for these tiers overlap so heavily that quoting them is close to useless. That overlap is itself the point. A number labeled "cabinets" tells you nothing. The tier, the box material, and the lead time tell you everything.

Lead time is the part homeowners underweight. A bid promising a finished kitchen in six weeks while specifying custom cabinets is describing a schedule the contractor does not control. The cabinet shop does. Look at the sequence a kitchen remodel actually runs in and you can see how a late cabinet delivery stalls everything queued behind it.

Some of the gap is the business model, not the work

Here is the part no contractor will put in writing for you. Two firms can perform the identical kitchen, hire the identical subs, and still have to charge different numbers, because their overhead is different.

NAHB’s 2026 Remodelers’ Cost of Doing Business Study, which covers fiscal 2024, splits the results by business model. General remodelers averaged a 22.2% gross profit margin. Design-build remodelers averaged 31.0%. Industry wide, the average was 29.9%. One limit you should know about: those figures are self-reported by NAHB members, and membership skews toward established firms, so the operator working out of a truck barely shows up in the sample.

That nine point spread is not padding. It is the showroom lease, the designer’s salary, and the person whose entire job is answering your texts within the hour. The spread widens wherever a firm carries a showroom, a designer and a project manager. It narrows toward the low twenties when the contractor is the estimator, the project manager and half the crew. You may want all of that or none of it. Either way it explains a real slice of the distance between the two bids, and it says nothing at all about the tile setter each of them hires.

We used to write here that net margins land in the low single digits. That was the flattering version of the number and we had not checked it. Fiscal 2024 net margin averaged 6.3%, which NAHB calls the highest remodelers have reported since 1996. Low single digits described fiscal 2021, at 4.7%. Split by model the nets run under the average: 1.8% net for general remodelers, 3.9% for design-build. The real numbers still make the original point. Six cents on the dollar, or under two, is not somebody getting rich off your kitchen. It is what it costs to run the kind of company you picked.

What a cheap kitchen bid quietly leaves out

A low bid got low somehow. Usually it is one of these, and usually it is not disclosed:

• Allowances set below what you will actually pick, especially countertops, tile, and lighting.
• Appliance installation priced as though it is free. It is generally billed per appliance, and somebody still has to pull the old range and haul it away.
• Cabinet trim treated as an afterthought: crown, light rail, filler strips, toe kick, and scribe moulding are the difference between installed cabinets and finished cabinets.
• Electrical brought only to what exists today rather than to what the inspector will want, which is a different number.
• Drywall and floor patching where a wall or an island moved. New flooring rarely matches an old patch.
• Permits and the dumpster. Whether a permit is required turns on your scope and your city, but a remodel that moves plumbing or adds circuits usually needs one, and the fee is real. So is the dumpster.
• The temporary kitchen. Six weeks without a sink has a cost even when it does not have a line item.

None of these make a contractor dishonest. A bid is a sales document, and a contractor who itemizes every one of these while a competitor leaves them off is going to lose on price to somebody who is quietly betting you will not notice until the walls are open. A few of the items are yours to take back, too. If you are willing to tear the old kitchen out yourself, that line comes off every bid on the table, though the answer is not automatically yes.

How to compare kitchen remodel quotes

Spread the bids out on the table and work through them in this order. Save the totals for last, because the total is the least informative number on the page.

1. 1Find every line with the word allowance on it. Write the figures side by side. This one step explains most gaps.
2. 2Ask each contractor what happens to an allowance overage, and whether their margin gets applied to it. Get the answer in writing.
3. 3Confirm all three bid the same tier. Refacing is not replacing. A minor remodel is not a major one.
4. 4Compare cabinets by tier, box material, and lead time. Not by the dollar figure.
5. 5Check for a contingency line, separate from the allowances. If none exists, ask who pays for what is found behind the wall.
6. 6Count the extras: appliance install, trim package, permits, dumpster, drywall patching, electrical upgrades.
7. 7Look for the design fee. Design-build firms often fold it in. A general contractor may expect you to arrive with a plan already drawn.
8. 8Only now, compare the totals. By this point you usually already know which bid describes your kitchen.

Whatever you settle on in that conversation has to survive the walk to the signing table, so the allowance figures, the overage rules and the exclusions all need to land in the paperwork you sign. Run through the clauses your kitchen contract has to spell out before you put a deposit anywhere near it.

What this exercise gives you is an understanding of why the numbers differ. Whether any one of them is a fair price for your scope, in your market, is a separate question with a separate answer, and it depends on things no article can see from here.
