How accurate are these percentages?

Within ±3-5 points for most US weddings. The Knot, Brides.com, and Bridal Bar all publish near-identical splits — variation comes from regional (NYC catering > Midwest), style (DIY shifts flowers down), and personal priorities.

Where do most couples actually overspend?

Surveys consistently flag flowers + decor (37% overspend), photography (28%), and reception extras like sparklers/photo booths (24%). Contingency line exists precisely to absorb these.

Should the engagement ring be in the budget?

Most planning tools EXCLUDE it as a pre-engagement expense already incurred. Average US engagement ring: $5,000-7,000 (The Knot 2024). Wedding bands ARE in the budget (typical $1,000-2,000 combined).

About this calculator

US median wedding cost in 2024 was about $30,000 (The Knot 2024 Real Weddings Study) — but the spread is huge: 25th percentile under $15k, 75th over $45k, luxury $100k+. Catering + venue together typically eat ~40% of the budget; photography 10%; attire 8%; flowers 8%; music 8%; the rest fills out into ten smaller categories. The single most useful planning number is the per-guest total cost, because it scales the whole budget against the only lever a couple usually controls: invitation list. Cutting the list from 150 to 100 guests saves more than any other line item. The 10-15% contingency line is non-negotiable in industry guidance — weddings consistently exceed budget because of last-minute "we forgot X" charges. Style presets shift the splits: intimate weddings spend more per-guest on photo/attire; destination shifts to transport; DIY redirects flowers/decor savings to venue and photo.
