What a kitchen renovation really costs — and where the money actually goes
By Marta Oliveira · Updated October 2026 · 9 min read

Most homeowners walk into a renovation with a number in their head and walk out having spent half again as much. The gap is rarely the appliances. For a mid-range kitchen in a US metro, the typical all-in range is $45,000 to $80,000, and cabinetry alone takes 30–40% of it. Time is the other budget. Plan on eight to twelve weeks from demo to a working sink, and more if anything structural turns up behind the walls.

The decision that moves the number most is the one people make last. Custom cabinetry versus semi-custom is the single biggest trade-off in the whole project — the difference can be the entire cost of the appliances. Before you sign anything, there are three things a quote should never hide: who pulls the permits, what happens if a material is back-ordered, and whether the price is fixed.

Quote #2241 — Rua da Prata kitchen
Hi Dana, quote attached as discussed. Earliest start is 12 January; valid 30 days. Permits would be on your side.

NOTES
- quote: €58,400 — under ceiling
- start: 12 Jan — matches note
- flag: permits on you
THEN, IN CLAUDE
"Using my Kitchen board — which contractor fits the look and the budget?"
Lisbon Build Co. — €58,400 is under your ceiling, the thread rates them well on oak joinery, they quoted semi-custom oak which matches the pin, and they can start 12 January like your note says. Two things to confirm: permits are on you, and the range needs a 240V circuit — it's in their electrical line, but check the amperage.
