Woodworking can get crazy expensive, but like most hobbies, you can get into it gradually for relatively low cost. I started with a cordless drill and a circular saw, then gradually bought used tools and restored them. If I were to buy everything new in my shop, it would easily be $15-20k, but I've spent maybe $2k over 5 years. The most I've spent on any one tool was a $400 miter saw a few months ago on sale, almost everything else has been stuff that's older than me or inexpensive tools that work just as well as pricier options.
Good hardwood is fucking expensive though. I found a local mill where I can get cherry for $4/bdft or walnut for $5.50/bdft (bdft = board foot, volumetric measurement equivalent to 12"x12"x1"). Somewhere like Woodcraft charges $15-18/bdft for walnut, which is $60+ for a 6" wide, 8ft long, 1" thick board.
ETA:
It does annoy me when every woodworking video comment section is bombarded with complaints about how expensive tools are. Yes, Sawstop and Powermatic are obscenely expensive. A DeWalt job site table saw is more than enough for most hobbyists starting out. So is a used saw you can get for $100 or less. It's very easy to blow through $20k outfitting a shop, but it's also very easy to outfit a shop with old, quality tools for a fraction of that price. This is what I've spent over five years
- 6" Jet jointer from 1973: $240
- 12" Parks planer from 1943-1986 (no idea on exact date): $200. Used a 13" Woodtek lunchbox planer for a few years before this. I got that for free because they don't make linkage gears for it anymore, and I was able to 3D print replacements.
- DeWalt job site table saw, new in 2018: $325
- Wen drill press, new in 2019: $70
- Wen scroll saw, new in 2019: $60
- harbor freight miter saw, used: $80 (fuck this thing, would never cut square no matter how much I tried to tune it)
- DeWalt compound sliding miter saw, new 2023: $400
- Harbor freight lathe, new 2020: $150-200 (don't remember exactly)
- shaper from 1978 + $2k in tooling: $40 at auction
- 7-10 various hand planes, all used from eBay or marketplace: $80
- knockoff 14" delta bandsaw from late 80s: $40

- slow speed bench grinder, new 2021: $90
- various hand saws, 2016-2023: probably $100
- various chisels, new 2016-2023: ~$120
All in, $2,100 over 5 years. I sold ~$1,500 worth of random projects in that time, and gained a ton of enjoyment from it.
Even if you do go big and spend a lot of money on tools, as long as you have disposable income and you're not forgoing your/your family's basic needs, there's nothing wrong with spending money on things you enjoy. It's ok to enjoy things.
