5 Smart Ways to Throw a Birthday Party Under $100

🔎 Disclosure: Heads up, babe: some links here are affiliate links, which means you might throw a tiny commission my way if you buy (zero extra cost to you). Only things you’d actually use and love get shared on this site.

1. Host a Backyard Party Instead of Renting a Venue

You don’t need a fancy rented space to make your party feel special.

Your backyard (or a friend’s!) can turn into the perfect budget-friendly venue with just a little creativity.

Think cozy lights, upbeat music, and food that feels homemade. Not overpriced.

You can:

  • Hang string lights or fairy lights to instantly make the space magical.
  • Use foldable tables and chairs from home or borrow from friends to save cash.
  • Play your favorite Spotify playlist and let your guests dance under the stars.
👉 Here's How You'll Do It: Ask your closest friend to co-host in their backyard or clear your patio, decorate with what you already have, and set up some music.

Make It Easy: Consider solar string lights to skip the cords and create that warm backyard glow.


2. Make Your Own Decorations with Dollar Store Finds

Store-bought decorations are cute… until you realize they cost more than the cake.

You can DIY almost every decoration for a fraction of the price and still make it look Pinterest-worthy.

It’s all about being clever, not crafty.

Try these:

  • Buy balloons, streamers, and tablecloths from your local Dollar Tree. Everything’s a buck!
  • Create a photo backdrop using a shower curtain, fairy lights, and some paper flowers.
  • Use mason jars as vases, candle holders, or candy containers.
👉 Here's How You'll Do It: Visit your nearest dollar store, pick a color theme, and grab everything that matches. It’ll look intentional and stylish.

Make It Easy: Grab a hot glue gun set to make DIY decorations in minutes without a mess.


3. Bake a Homemade Cake That Looks Bakery-Perfect

A fancy cake can cost as much as your electric bill. But baking your own? Game changer.

You can make a cake that tastes even better (and costs under $10) with some smart shortcuts.

Plus, your guests will think you spent all day on it when it actually took you an hour.

Here’s how to pull it off:

  • Use box mix hacks like adding an extra egg or swapping water for milk to make it richer.
  • Decorate with fruit, whipped cream, and sprinkles instead of pricey fondant.
  • Bake in two smaller pans to stack them and make it look professional.
👉 Here's How You'll Do It: Whip up your cake a day before the party, decorate it after cooling, and refrigerate. It’ll taste even better chilled.

Make It Easy: Use a hand mixer with multiple speed settings to whip up smooth, bakery-style frosting in minutes without breaking a sweat.


4. Serve Simple Food That Feeds Everyone for Less

Here’s the secret: people remember the fun, not the menu.

You don’t need a catered spread to make everyone happy. Just good, simple food that feeds a crowd.

Finger foods and DIY stations win every time.

Some easy ideas:

  • Make-your-own taco bar using tortillas, beans, cheese, and salsa.
  • Big-batch pasta or salad that costs little but serves many.
  • Pitcher drinks like lemonade or iced tea instead of buying soda cans.
👉 Here's How You'll Do It: Choose one crowd-pleaser dish and make it in bulk. Trust me, no one complains about too many tacos.

Make It Easy: Use a slow cooker to keep your food warm and ready without babysitting.


5. Plan Fun Group Games Instead of Costly Entertainment

You don’t need to hire a DJ or rent a bounce house to have fun.

Games bring everyone together and cost next to nothing.

And yes, adults love them too (especially when there’s a prize involved).

Some fun and cheap ideas:

  • Scavenger hunt around the yard or house. Add silly clues for laughs.
  • Trivia games about the birthday person. Make it funny and personal.
  • DIY photo booth using a curtain backdrop and your phone on a tripod.
👉 Here's How You'll Do It: Pick 2–3 easy games, set up everything before guests arrive, and use small prizes like candy or gift cards.

Make It Easy: Consider a Bluetooth party speaker to play music or game sound effects without renting equipment.

Hey, I'm Lily! I'm a mom who's really good at two things: stretching a dollar and talking about stretching a dollar. I created Money Vice after one too many grocery trips where I watched my total climb and thought, "There's gotta be a better way." Spoiler: there is. Think of me as your money-savvy friend who's always got a tip (and coffee in hand).
