Choose carpet for warmth, quiet and cushion — nothing on this site beats it for comfort underfoot or acoustics. Choose tile for water resistance and permanence — porcelain survives what carpet can't, and outlasts it by decades. The two rarely compete for the same room; where they do, the deciding question almost always comes down to whether that room ever gets wet.
Installed cost includes material and professional labor. Ratings are relative across all 21 materials on this site, not absolute scores.

The points that decide this in practice — not the spec sheet items that read well but rarely change anyone's mind.
Nylon carpet rates the maximum score on both comfort and quiet; porcelain rates the minimum on both. That isn’t a close call dressed up as one — of the 21 materials this site rates, these two sit at opposite ends of the same two scales, which is exactly why they rarely compete for the same room.
Porcelain rates the maximum water score on this site, effectively impervious. Carpet rates near the bottom, and the real failure point isn’t the fiber but the pad beneath it — liquid goes through the face and into the cushion, then the subfloor, which is where a spill turns into an odor problem that cleaning the visible surface won’t fix.
The old advice to strip out all carpet for allergy sufferers is more nuanced than it used to be. Carpet traps dust, dander and pollen in the pile rather than letting it recirculate, and a nylon floor vacuumed regularly with a sealed HEPA machine can perform reasonably well. Porcelain has nothing to trap anything in, which means less ongoing effort for the same result — whatever lands on it stays on the surface, where a damp mop reaches it, with no vacuuming discipline required to keep it that way.
Carpet is a ten-to-twenty-year product that gets replaced as a whole room, pad included, when it mats down or the fiber fails. Porcelain carries a life expectancy several times longer, but it isn’t maintenance-free in a wet room — cement grout needs resealing every one to two years, which is a smaller, more frequent task than carpet's eventual full replacement rather than a substitute for one.
$4.00–$10.00 per sq ft installed, lasting 10–20 years — about $0.47 per sq ft per year.
If you buy one upgrade, make it solution-dyed nylon over a quality 8 lb pad. It costs roughly 15% more and routinely doubles usable life.
$8.00–$29.00 per sq ft installed, lasting 50–100 years — about $0.25 per sq ft per year.
The tile is rarely the expensive part. Substrate prep, uncoupling membrane and skilled labor are — and skimping on those is what causes the cracks people blame on the tile. On wood-look plank, put two more questions to any bid: what offset, and what grout joint. A 50% brick-set on a 48" plank with a 1/16" joint will generate lippage complaints no matter how good the tile is.
Tile is the lower-effort choice, not the only correct one. It has no pile to trap anything, so a damp mop keeps it clean with no ongoing discipline required. Carpet isn’t automatically worse — vacuumed regularly with a sealed HEPA machine, it traps allergens in the pile rather than letting them recirculate the way a neglected hard floor also does. The real question is whether the vacuuming will actually happen; see the fuller explanation on the technical terms guide.
Carpet, usually by a wide margin at installation — nylon carpet's combined material-and-labor range on this site runs well under half of porcelain's. Tile's much longer life expectancy changes the multi-decade math, but the upfront cost gap is real and it is the reason carpet remains the default in bedrooms and living rooms.
Carpet over tile is straightforward — pad and carpet lay over any flat, hard surface. Tile over carpet isn’t done; carpet and pad have to come out and the subfloor has to be flat and stiff enough for tile before installation starts, which usually means self-leveling compound and an uncoupling membrane, not a simple layer-on-top job.
