Standard Breakdown
These are starting points. Adjust based on your priorities. The biggest budget lever is guest count, as food and beverage are the largest single expense.
Worked Example
A $30,000 wedding with 120 guests.
- 01Venue & reception = $30,000 x 45% = $13,500
- 02Photography = $30,000 x 12% = $3,600
- 03Attire = $30,000 x 10% = $3,000
- 04Flowers = $30,000 x 8% = $2,400
- 05Cost per guest = $30,000 / 120 = $250
Frequently Asked Questions
What is the average wedding cost?
The US average is about $33,000 (2024), but this varies enormously by region. New York City averages $70,000+, while rural areas may average $15,000-20,000.
Where can I cut costs?
Biggest savings: reduce guest count, choose off-peak dates (Friday, Sunday, winter), use a non-traditional venue, limit the bar, and DIY decorations and invitations.
Should I have a contingency fund?
Yes, 5-10% of your budget. Unexpected costs always arise: last-minute vendor changes, weather contingencies, forgotten items, and gratuities.
