Is this realistic

Depends on what you are envisioning! I would say that’s very very tight for that location, specifically. There are so many costs that you don’t think of right away that tend to add up and also service fees and tax. Our budget is 15,000 and we are having a fancy-ish destination wedding for 80 people.

I think its realistic if you stick to the budget. Maybe you can have family and friends assist using their talents to cut back some cost like: invitations, decorations, flowers or food,

^ I would really recommend against having family (or yourself) cook the food for your wedding. Personally, I think that budget would be really hard to swing. If you go minimal-to-no decor and choose a budget-friendly catering service (BBQ, Mexican, or Italian) and pick a cheap or free venue (public park, a generous friend's land, etc.) then it could be possible. However, that's a HUGE guest list to consider. Food, chairs for everyone, etc. really needs to be taken into consideration, and thats not including the dress, makeup/hair, tux, bouquets, etc.

I'd really start budgeting all of this out now and grabbing quotes from local vendors!

I can’t say much about costs in CO-I’m in WA, so location might play a factor. Our original plan was 200 guests and our budget was $15,000, though we were trying to stick as close to $12,000 as possible. However, we’re cutting back to just 20 people due to COVID, so I can’t tell you what the final cost would’ve been since our major expenses were still to come.
We’re doing a lot of things ourselves or have various connections. Ceremony is at my parents farm. Friend is catering. Relative is doing flowers. My piano teacher growing up was going to do ceremony music. Friend was going to run music/sound for reception. Decorations are DYI.
We cut costs wherever we could, and our budget felt very doable. Plan it out, figure out what is most important for you (photography was ours, so that’s where we splurged), and then stick to it.

Costs vary across the country. Where I live, that would be impossible. We had a roughly 80 person wedding on a "budget" ... and our budget was twice yours. But we're in NYC.

You can use the "Planning Tools" and "Vendors" tabs up above, to try to get a good idea of what costs are in your area!

Research is your best friend, and being ruthless about what matters to you and what doesn't. (Don't care about flowers? Use fake, or just don't get any! Have a wine and beer bar, no liquor, etc.)

Anything is possible. You will have to decide what is most important to you and your fiancé. Some of the least important things will have to get the boot. You may have to stick to bare minimal or no decorations. I think the biggest concern would be finding an affordable venue for that size. Even if you get a park or garden/open field for free, you’ll still need seating for your guests ($ for rentals). IF you serve food, you can stick to hor d’oeurve, finger foods will be your friend (saves on extra tables, silverware, plates, and making clean up easier). I’ve heard of people having guest take pictures throughout the night n sending to a website set up by bride and groom ( saved on photographer and they actually got some really cool, funny, and great candid pics of wedding party and guests). Be creative but stay realistic. Remember this is a night you (and others) will ALWAYS remember.

Absolutely ! I think that’s doable

That seems extremely low for such a high guest count to me. My FH also originally wanted a large (not 200 people large) guest count with a budget of $10,000. What we did was sit down and talk about what we imagined the day would be like, what kind of food, how many people are in the wedding party, how long do we want the reception to be, dj or band, what kind of ceremony etc. Once we had an idea what our vision was I did some research. I looked at the wedding wire planning tool that shows the average cost of different venders, found some venues that fit our vision and found thier prices for renting. Once that info was gathered we came back together to see if our budget was realistic. In our search we found food alone was $40-60 per guest without appetizers, plates, servers, drinks, or cutlery for our area so we upped our budget as there was no way we could afford to feed people AND have a wedding under our budget.
We also cut alot of things like dacor, I am borrowing glass bottles and vases, buying a few bundles of flowers from the grocery store to do single flower centerpieces with books and things I already own. We are not having a band or dj most likely. I am looking at buying a used or under $400 dress and my mom is doing the tailoring if needed as she is a retired costume designer.
But the most expensive stuff is going to be venue if you don't go with a government building or park and food. Also prices change depending on the season/month/day of the week you pick. Some the prices double or triple during peak season.

It really depends on what type of wedding you want. $15,000 could work for 200 people. That just means you guys are doing set up, cooking, cleaning, every single detail yourself. Do you want to enjoy your wedding or worry about refilling food halfway through the night? There are a lot of little details you or your close family members would have to worry about. So they would be working not enjoying the wedding.

I would start with gathering quotes first from Venues first sometimes they will do everything for you. If you can't find a venue in your area that will do food, alcohol, and set up. Then you look for venues that are cheap. and then spend the money on catering ( someone to cook the food and refill), then drinks, then rentals (tables, chairs, dining utensils, etc.) if you still see you can't afford it, start cutting your guest list. There are also additional things for weddings that people just forget cost lots and these are all the extras (not necessities).

- Flowers ( centerpieces, bouquets, boutonnieres, altarpieces), Officiant, Music, Parking, Photographer or videographer, Stationery( save the dates, invites, programs, place cards, thank you cards, postage all for 200 people). Attire( dress, veil, shoes, suit, stores, rings), Beauty (hair and makeup), TIPS ( usually have to tip out all vendors).

I have 100 people guest list and we are spending 20K but we are also in CA. I hope this helps a little so you can get off to a good start.

If you have a planer he or she can help with this as they have an inside discounts sometimes, and can spreadsheet the cost. If not here are a few options...Rent the flowers, have the place be on a freinds or family's property or a venue you get a tax back on, have a family style meal( cheaper than single serve catering, no wait line, friend of mine did this with smoker some ribs and salmon everyone brought side, soooo good), maybe look at second hand outfits and decor to resale after as well, the plates and silverware could be bamboo( which is disposable and looks magical), there are now showers where the guests, instead of bringing a toaster as a gift, bring spirits to have at the wedding, no favors, talk to starter up business for dj, photographer, ect. Make your own fake cake, and serve home made sheet cake, pay high schoolers for cleaning crew, if it's just adults serve drinks in dispenser.
