Often forgotten

What am I forgetting?

  • Under-cabinet and in-cabinet lighting transformers ($800 - $1,800): Often left as a surprise electrical extra.
  • Subfloor rot or leveling under old cabinets ($600 - $1,500): Old dishwasher leaks frequently require new subfloor plywood before tile/LVP.
  • HVAC toe-kick duct relocations ($400 - $900): If you change cabinet depth or add an island, supply ducting must be routed properly.

  • Countertop edge profile, slab selection, seam count, and cutouts
  • Plumbing rough-in and shut-off valve replacements

How it works

A better estimate starts with visible line items

Projects go over budget when costs hide inside one round number. Here is how we keep every dollar visible. Read our methodology →

01

Split out every cost

Materials, labor, permits, and haul-away each get their own line instead of one lump sum.

02

Adjust for your city

A kitchen in Austin costs less than one in New York. We adjust for local trade wages, permits, and sales tax.

03

Compare quotes fairly

A lower quote is only cheaper if it includes the same scope, permits, disposal, and materials.

FAQ

Home project cost questions

How does HomeJobCost estimate project costs?
Each calculator breaks a project into line items (materials, labor hours, permits, disposal, and sales tax), multiplies them by your project size and finish level, adjusts for your metro’s labor rates, and adds a contingency. See our methodology page for details.
How much does a kitchen remodel cost in 2026?
An average-size kitchen (about 150 sq ft) with mid-range finishes typically costs $31,000 – $42,500 at national-average prices. Use the kitchen remodel calculator for a range based on your size, finishes, and city.
How much does a bathroom remodel cost in 2026?
A full hall bath (about 55 sq ft) with a tiled shower and mid-range finishes typically costs $16,000 – $22,000. A cosmetic refresh costs much less; a primary suite costs much more.
Why do contractor quotes for the same project vary by $10,000 or more?
Usually because of scope, not labor rates. One contractor includes permits, a dumpster, and quality materials; a lower bid leaves out permits, excludes drywall repair, or uses small allowances for finishes. Our Quote Checker flags these gaps.
How much should I set aside for contingency?
About 10% for cosmetic projects in newer homes, and 15–20% for older homes or projects that open walls and floors, where hidden rot or outdated wiring is common.
Are my estimates and quotes private?
You never need to give a phone number or email, and we do not sell contact details to contractors. The calculators run in your browser. When you check a quote, its text is sent to our server and an AI provider to produce the report (see our Privacy Policy).
