What drives the cost
A kitchen remodel is priced from two independent levers: size and finish level set the materials bill, while scope sets the labor bill. Cabinets, countertops, appliances, and flooring all scale with square footage and get more expensive per foot as you move from a budget finish to luxury. Scope works differently: a cosmetic refresh (new fronts, counters, paint) needs far less labor than a standard swap-and-reinstall job, and a full gut adds plumbing and electrical relocation on top of the base install labor, which is why it costs the most even at the same size and finish.
How the ZIP adjustment works
Materials are priced at national averages: a mid-range countertop costs about the same whether it's installed in Ohio or California. Labor doesn't work that way, so this calculator multiplies the labor and structural line by a regional index derived from your ZIP code's first three digits. A factor above 1.0 means labor in that area tends to run above the national baseline; below 1.0 means it tends to run cheaper. This is a planning index, not a quote: it reflects broad regional differences in contractor rates, not the specific bid you'd get from a specific crew.
Budgeting tips
Treat the low-high range as your realistic planning window, not the total. Get at least three itemized quotes before committing to a budget, and hold back 10-15% as a contingency for anything hidden behind the walls (old wiring, water damage, out-of-code plumbing) that only shows up once demo starts. If you're doing a full gut, ask early about permit costs and inspection timelines since they can add weeks even when the construction itself goes smoothly.
