Why Are Kitchen Remodel Quotes So Different?

The three bidders are probably not the same kind of company either. 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, and their overhead makes it impossible for them to land on the same number.

So work through the bids in the order that moves the most money, which means starting with the line that moves more of it than any other.

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 the placeholder a contractor drops into the bid for a thing you have yet to choose. Your countertop gets one. So does the tile, and usually the lighting and the appliance package. It reads like a settled price, and every figure in it is provisional.

A bid can read "Appliance allowance: $6,000" and total $52,000. Another can read "Appliance allowance: $14,000" and total $60,000. Those two kitchens are the same kitchen. The $8,000 sitting between them comes down to one estimator picturing a builder-grade package while the other pictured a counter-depth refrigerator and an induction range.

How a low allowance turns into a bigger bill

Set the allowance low and the headline number wins the job. Then you walk into the appliance showroom and put your hands on the counter-depth refrigerator, because everybody does. The allowance was $6,000 and the package you picked is $14,000, so $8,000 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 cheaper selection the estimator had in mind.
• The overage is often marked up. You rarely pay the $8,000 difference on its own. 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.

While the bids are open, check something adjacent: whether any of them carries a contingency as well as its allowances. An allowance covers the tile you have not picked. A contingency covers the rot nobody knew was behind the dishwasher. A bid can fund the first and ignore the second, and then whatever the demo crew turns up on day two comes out of your pocket instead of a reserve. Getting both written down properly is a job for your kitchen remodel contract rather 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, the 38th annual edition, 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. No rung on it is 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. So appliances are inside that scope, and the boxes are the thing that stays.

The major is a different animal. It pulls the cabinets out and replaces them outright: 30 linear feet of semi-custom wood boxes, plus a 3 by 5 foot island. What that scope never says is whether a wall comes down, whether any plumbing moves, or whether the sink ends up somewhere new. The report is silent on all three, so it cannot settle the question for you in either direction. Ask each bidder outright rather than reading it off the price.

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.

That 113% deserves one caveat, because it measures belief, not sales. Zonda builds the resale side by surveying more than 6,000 Realtors and asking each what value a given project adds to a home’s sale price. The cost side is modeled as well, from Bureau of Labor Statistics and Bureau of Economic Analysis price data, with Verisk’s XactRemodel estimating software used to work out how those prices vary market to market. Both ends are professional judgment. No invoice and no closing statement is anywhere in the number.

Cabinets move more of the number than anything else

So when one bid runs $20,000 heavier than another, start at the cabinet line and work outward from it. The last time NKBA, the kitchen and bath trade association, published the breakdown, US kitchen cabinetry was worth $19.9 billion a year against $80 billion of spending on kitchen products overall. That puts cabinets at about a quarter of everything bought for the room.

Two things to know before you lean on that quarter. Both figures are 2017, and no newer public breakdown has replaced them, so read the proportion and ignore the absolute size. And both count product and materials only, with labor, design and installation left out of each, which is exactly what makes the comparison fair: the same things are in and out of both numbers. The ranking is the durable part. 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. Those tiers are a sales convention rather than anything a body certifies. What the Kitchen Cabinet Manufacturers Association actually certifies is performance: under its quality certification programme a wall cabinet is loaded to 600 pounds without visible failure, and a door is opened and closed through a full 90 degree swing 25,000 times. Nothing KCMA publishes about that programme sorts cabinets into stock, semi-custom or custom.

• 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 the certification tests what a cabinet survives rather than what it is built from, so a certification seal on the door tells you nothing about what is behind it. Ask what the box is made of. Do not read it off the tier.

Per linear foot the published ranges for these tiers overlap enough that quoting them would not help you, which is the useful thing to know about them. When you set the cabinet line from three bids side by side, compare the tier, the box material and the lead time. The dollar figure on its own will not separate them.

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

Two firms can perform identical work, hire identical subs, and still have to charge you different numbers, because what each one carries behind the job is different.

NAHB runs a Cost of Doing Business study on residential remodelers, and its 2026 edition covers fiscal 2024. Industry wide, remodelers averaged a 29.9% gross profit margin, meaning roughly 70 cents of every revenue dollar went straight back out on labor, materials and subcontractors. One limit worth knowing: the figures are self-reported by the remodeling companies that answer the survey, so the operator working out of a truck is thinly represented in them.

What sits inside that overhead is the showroom lease, the designer’s salary, and the person whose entire job is answering your texts within the hour. A firm carrying all three has to price them in. A contractor who is his own estimator, his own project manager and half his own crew does not. You may want all of that or none of it. Either way it explains a real slice of the distance between 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, when it was 6.8%. Low single digits described fiscal 2021, at 4.7%, and 2018, at 5.2%. The corrected number still makes the original point. Six cents on the dollar leaves very little room for anybody to be getting rich off your kitchen. That is roughly what it costs to keep the kind of company you picked in business.

The costs a low bid assumed you would absorb

A low bid got low somehow, and usually it is one of these seven:

• 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.

A bid is a sales document, and the contractor who itemizes all seven loses on price to the one who leaves them off. The incentive sits in how bidding works, not in the man holding the clipboard. 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.

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. A refacing job and a full box replacement are different products, and so are the minor and major scopes.
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. 8Now compare the totals. By this point you usually already know which bid describes your kitchen, so the number confirms what you already worked out.

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.

By the end of that pass the three proposals stop being three prices and start being three different jobs, which is what they were the whole time. Whichever one you sign, you will know what you bought and what you turned down.
