Where to spend and where to save
The trick to a cheap party that looks pricey is knowing where your money matters. Spend on the things guests notice and photograph. Save on everything else.
Spend a little on your focal point and the cake. Save on tableware, favors, and food by keeping them simple. One styled corner does more for photos than a room full of cheap decorations.
Budget decoration ideas
A few simple pieces go a long way. Here are the ones that give you the most impact for the least money:
- A balloon garland in two or three colors. It is cheap to make and looks amazing. Here is how to make a balloon garland without a kit.
- A simple backdrop using a bed sheet, streamers, or fabric. See more party backdrop ideas.
- Dollar-store banners and paper decorations in your colors.
- A styled cake table as the main focus.
- Fresh flowers or greenery from the garden for free.
A balloon garland and a simple backdrop give you a big look for very little money.
Real DecorWillow Case Study
Recently, the DecorWillow team styled a complete kid’s birthday party for just $85. We spent $40 on a DIY balloon garland and cake, borrowed a drink dispenser, and bought $15 worth of dollar-store plates and napkins. The result looked like a $300 setup because we focused entirely on one amazing backdrop wall.
Before and after
You do not need to decorate the whole room. Style one corner and it changes everything. Here is the same corner before and after.
One styled corner becomes the photo spot, and it costs almost nothing to pull off.
Cheap food and cake ideas
Food adds up fast, so keep it easy. A few smart choices save you a lot:
- Serve finger foods and snacks instead of a full meal.
- Make a simple homemade cake, or buy a plain one and add your own toppers.
- Set out a popcorn or candy bar. It looks fun and costs little.
- Use a big drink dispenser with lemonade or punch instead of individual cans.
Finger foods and a big drink dispenser look fun and cost far less than a full catered meal.
DIY decorations that look expensive
A little effort saves a lot of money. These DIYs look high-end but cost almost nothing:
- Paint dollar-store vases in one color for a set that looks custom.
- Make paper flowers for a backdrop.
- Tie ribbon or fabric strips onto a string for an easy fringe backdrop.
- Fill glass jars with fairy lights for soft, pretty lighting.
Simple DIYs, like painted vases and paper flowers, look custom for just a few dollars.
Party favor ideas on a budget
Favors do not need to be pricey. Small and cute wins every time:
- Candy or cookies in kraft bags with a ribbon.
- A single wrapped treat at each seat.
- Bubbles, stickers, or small toys for kids.
- Seed packets or a small plant for adults.

Guest count planning
For a party of 10 to 15 guests, one balloon garland, one cake, and a favor per person is plenty. Buy a few extra favors and treats for last-minute guests. Keep food simple and let people help themselves.
Money-saving tips
A few habits keep your costs down:
- Shop the dollar store first for tableware, banners, and favors.
- Check thrift stores and community marketplaces (like Facebook Marketplace) for second-hand cake stands, drink dispensers, or unused party supplies at a fraction of the cost.
- Reuse decorations you already own. A vase or string of lights works for any theme.
- Skip helium. Air-filled balloons are cheaper and last longer.
- Borrow big items, like drink dispensers or cake stands, instead of buying them.
- Make food yourself rather than ordering platters.
Tight on space?
For 6 to 8 guests, make a garland of about 30 balloons, hang one sheet backdrop, and serve a small cake with two snacks. The whole setup costs close to half of the full budget.
Helpful safety sources
A few trusted places for the safety points in this guide:
