According toTHISarticle Americans will spend $9.1 billion on Halloween.
Well that makes sense I see almost as many places selling Halloween decorations as I see selling Christmas stuff. And people will set up[ and leave up Halloween decorations as much as Christmas. Its not even unheard of to see 2 houses next to each other with both set up.
So I’d like to ask, how much do you spend on Halloween?
Do you do a big display?
Do you do a home haunted house?
Do you host or attend a costume party?
Since the OP is asking for personal experiences, let’s move this to IMHO.

$0. I rent an apartment and I’ll be working that night.
Usually about a hundred bucks total counting a party or two we attend and the Phoenix Phall Phunfest at Knoebels; the Halloween part of it. The rest we would do no matter what. Our record was maybe a grand but we did three road trips, counting motel nights, for several zombie walks.
Ten bucks or less on candy. I hang up a wooden vampire bat on the door I got at a craft fair decades ago for $2. That’s about it.
Zero. I’d spend less if I could. I hate pageantry, especially if it is commercially motivated.
When I lived in suburbia it’d be $10ish on candy for the kids. More back in the 1980s when kids still came around in number. Far less in the 2000s when they didn’t. $0 when I’ve lived in condos in kid-free zones. Such as I do now.
Costumes, decorations, and admission to commercial parties like at bars or restaurants? Adult lifetime total is $0.
I’ve certainly hosted or attended private parties and spent a sawbuck or two on booze & snacks. That’s about it.

We moved this year, so I really have no idea. If the neighborhood is generally ignored by trick or treaters, I’ll spend a little on a door decoration and that will be about it. If there legions of kidlets about, then the decorations get fancier and I spring for big bags of candy. I want to be known as “the house that gives full-size Snickers bars.”
Nothing at all. I always have candy in the house (sweet tooth is my weakness) and if someone rings the bell despite the light not being on, I give them some. But that doesn’t count as money spent for halloween in my mind.
Nothing ! When I first moved to my condo I went out and brought some candy thinking there would be a lot of kids coming . I waited and waited and not one child came to my condo . The next at school my daughter found out that school kids weren’t allowed to tick or treat here so I had my daughter bring all the candy to school the next day. It was a big disappointment to me b/c I was looking forward to seeing the kids Halloween costumes . I guess some farts complained about the kids coming here !
Probably nothing. Sadly.
When I first moved here I bought several bags of candy and only got 1 trick or treater. I haven’t had one since.
Do people still do trick or treating where other people live? I love it, I just don’t get kids coming to where I live for it. I like seeing all the costumes and giving out candy.
Well, Ima buy candy, but we’re gonna eat it. For a lot of years we bought candy, cut a pumpkin, drew on the sidewalk etc. But hardly any kids come through this little street. So we just stopped entirely after a while. But I still buy candy, of course.
About $100-200. My friends are really into Halloween and invite me to their party every year so I spend about $100 on a costume. Then I carve pumpkins so that’s a few bucks. This year I’m doing a Trunk or Treat so I have to buy candy for that and also decorate my car so it’ll cost a bit more than just buying candy for my house.
I’m not huge into Halloween. Not close to how much some of my friends are into it. But I enjoy dressing up and enjoy being a good neighbor so I drop the dough as needed.
(No I don’t need a $100 costume but it’s a lot of fun)
I live in an apartment complex with lots of kids, but if they trick or treat, they don’t do it here.
If I see Halloween pencils, candy, etc. on sale afterwards, I buy it and eat the candy or give the pencils to the elementary school up the street. I used to get a lot of TorTers in my old neighborhood, and I would give out pencils - and only had one complaint. :o He was a little boy about 4 years old who said, “She doesn’t have candy!” and a 40-something woman with him (grandma? mom? aunt?) said, “You be grateful for what you get.” I told him that it was a present and he was OK with that.
I said the same thing when I worked at the grocery store pharmacy, and we gave out toothbrushes.
$0
I don’t get any trick-or-treaters, and figure my money is best saved for the day after, when all the stores mark down the candy that didn’t sell to half price or even 75% off. THEN I stock my shelves. 
$0
I have spent far too many Halloween nights working to ever bother with the holiday. For instance, last year I was installing the lights for a Lenny Kravitz concert for a corporate event. And the year before that I was finishing the lighting in a car show booth. The year before that I was lighting a pharmacist’s convention. There’s always something.
I do a little haunted front yard sort of thing.
Under $20.00
Probably $40 or so on candy. I believe in giving the good stuff. No smarties or lame candy that no one really wants. I want to pay it back for the fun I had as a kid. Bonus-if I have leftovers, I get to eat it. 
We don’t decorate or anything though.
The number of ToTers that come by varies a lot from year to year. I still have some leftovers from 2016, and yes it’s still edible.
Maybe around 10 dollars. Usually just some Halloween owl decoration for work. I have about three or so I set up.
