Wedding Budget Calculator: Plan Your Wedding Costs

Reviewed by the CalculatorHub team, edited by James Graham. Allocates your total wedding budget across standard categories using industry-standard percentages. Last verified 14 June 2026.

The average American wedding cost approximately $30,000 in 2023, according to The Knot's annual survey, though costs vary enormously by region (New York City averages nearly double the national figure; the Midwest and South average considerably less). Guest count is the single most powerful driver of wedding cost: adding guests raises catering, venue, invitation, and favor costs proportionally. Wedding industry professionals use a set of conventional budget allocation percentages to guide couples in distributing their overall budget across categories. The venue and catering together typically absorb the largest share (around 50%), followed by photography and videography (12%), flowers and decor (8%), music and entertainment (8%), attire and beauty (8%), invitations and stationery (2%), transportation (2%), and a miscellaneous buffer (10%). This calculator takes your total budget and guest count, applies these industry-standard allocations, calculates a suggested dollar amount for each category, and shows the per-head catering cost. Use these figures as starting targets when contacting vendors; adjust the percentages to reflect your own priorities.
