Kitchen Remodel Cost Breakdown: Where the Budget Goes
Last reviewed 2026-08-25.
Kitchen “average cost” articles collapse a galley refresh and a wall-moving remodel into one number. FixerCalc does not. The kitchen calculator multiplies the rectangle you measure by an editable installed $/sq ft band, optionally bumps the range 25% if plumbing or walls move, then adds extras you already priced.
Use this guide to decide what belongs in that envelope, what to hire out, and how to read a bid next to the math.

Typical Project Fit
Typical fit: Hybrid project
Typical label: Hybrid project. That describes a common mix of finish work and hired trades. It is not a safety rating for your house.
What moves the cost
- Whether the sink, range, and walls stay put. Layout change is the largest jump the calculator models (a 1.25× planning multiplier, not an engineering takeoff).
- Cabinet quality and count. Stock boxes on the same footprint sit near the low end of a mid band; custom boxes and a new island do not.
- Countertop material and edge complexity—especially stone that needs a shop template after cabinets are set.
- Electrical and gas: new circuits, relocating a range, or adding an island receptacle.
- Hidden damage behind the dishwasher and under the sink once you open the room.
What the calculator includes
- Kitchen area as length × width of the working rectangle (default example: 12 × 10 ft = 120 sq ft).
- A quality-tier band that loads typical US installed $/sq ft defaults you can overwrite (mid-tier defaults are $200–$350 per sq ft).
- An optional 1.25× multiplier when you check layout change.
- A flat extras field for a known appliance package, design fee, or permit line you already have.
What the calculator may leave out
- A city labor index or a promise of what three contractors will bid.
- A separate cabinet takeoff, appliance SKU list, or stone slab waste.
- Temporary kitchen, dumpster, or living-elsewhere costs unless you type them into extras.
- Lead-safe or asbestos abatement if older finishes are disturbed.
DIY-friendly parts
- Painting after the messy trades are done
- Hardware, organization, and a temporary kitchen
DIY with conditions
- Stock cabinet assembly if you can keep boxes level and plumb
- Click-lock flooring rated for kitchens
- Backsplash tile on a sound wall
Parts often hired out
- Plumbing and gas moves
- New electrical circuits
- Structural openings
- Complex countertop install
Planning checklist
- Measure length and width of the kitchen, not the adjacent dining room.
- Write down keep vs replace for sink location, range, cabinets, and appliances.
- Run the calculator twice: layout unchanged, then layout changed, and look at both ranges.
- Ask every bid to split cabinets, counters, labor, electrical, and plumbing.
- If the house may be pre-1978, budget time for lead-safe practices before you sand painted cabinets or cut painted trim.
Worked example: 12 × 10 ft, mid tier, layout stays
These are the calculator’s shipped mid-tier defaults, last reviewed with the rest of the cost bands. They are planning bands, not your city’s labor rate.
- Area = 12 × 10 = 120 sq ft.
- Mid-tier defaults: $200–$350 per sq ft.
- Layout box unchecked, so multiplier = 1. Extras = $0.
- Low = 120 × 200 = $24,000. High = 120 × 350 = $42,000.
- If you then check layout change: 120 × 200 × 1.25 = $30,000 and 120 × 350 × 1.25 = $52,500.
Planning range without a layout change: $24,000–$42,000. With the layout bump: $30,000–$52,500. The midpoint is only the average of your range—not a bid.
Common mistakes
- Using listing square footage for the whole first floor instead of the kitchen rectangle.
- Adding the island as extra area when it already sits inside the rectangle you measured.
- Treating the mid-tier default as “what kitchens cost in America.” Overwrite the $/sq ft fields.
- Comparing a keep-layout bid to a move-the-sink bid as if they were the same scope.
Contractor quote checklist
- Does the bid keep the sink and range, or move them?
- Are cabinets, counters, labor, electrical, and plumbing separate lines?
- Are appliances in or out?
- What happens if they find water damage under the sink?
- Who templates stone, and after which cabinets are set?
Stop signs
- A bid is one lump sum with no scope attachment.
- Someone offers to move a gas line without a license your area requires.
- Demo reveals a wall you thought was partition and the ceiling line drops.
FAQ
- Does the calculator include appliances?
- Only if you put a known package in extras or raise the high $/sq ft because your bids bundle them. Magazine averages are inconsistent; the extras field is honest.
- Should I add the island to the square footage?
- If the island sits in the rectangle you measured, it is already in the area. A new island that also needs plumbing or electrical is a layout change, not extra floor area.
- Why is there a 1.25× layout multiplier?
- It is a coarse warning that moving plumbing or walls is not a surface refresh. It is not a load calculation or a plumber’s hours.
- Can I DIY the whole kitchen to hit the low end?
- Some finish work is DIY-friendly. Plumbing, gas, new circuits, and structural changes are often hired out. The low end of a $/sq ft band is not a coupon for skipping licensed trades your area requires.
- What about lead paint on old cabinets?
- EPA treats lead as a hazard in many pre-1978 interiors. Sanding or cutting painted wood can create dust. That work sits outside the $/sq ft range unless you add it in extras.
