There is the cost of goods and cost of installation.

Look at wood carefully...there is solid hardwood and engineered hardwood....installation can be different. One can be nailed to plywood (more expensive) and one can be glued down (less expensive.)

Tile is the same...if it is natural stone, it costs more to install. If it has a rectified edge, it costs more to install. If you have a pattern, it costs more to install.

So, look at the types you like first...

Enjoy your build!

10-100K

You have to do a lot more homework than that to narrow the guesses down. 10K would be on the low end for both with no decorative details done at all in the tile. Plain white tile baths and cheap engineered glued to slab. 100K would be multiple nice porcelain or natural stones done with listellos and decos and/or something other than a basic pattern and a good quality engineered or solid hard wood floor in an exotic with a premium finish. Probably no carpet anywhere. But if there is carpet, a decent but not super high end wool.

Our builder's cost was $7/sf for site finished 4" white oak (not engineered). That's installed with material. Have no idea what the install price is on tile - I would guess it varies considerably.

I am paying $2.50 a sf for prefinished 3/4 hardwood and $2.50 a sf for tile. That does not include any cement board underlayment for the tile. That is pretty much the going rate around here. The tile cost is for floor tile only.....showers/backsplashes are usually much more.

We have $7.50/sq ft for hardwood (stained and finished) and $8.50/sq ft tile. This will cover average flooring.

As long as you don't go with boutique woods (cherry/walnut) or specialty tile these allowances are fairly close to what to expect. Tile turned on point may cost $0.30/sq ft extra.
