How wedding budget calculator Works
The per-guest architecture
Wedding costs split into per-guest lines (catering, bar, favors — everything that multiplies) and fixed lines (photography, dress, venue base — everything that does not). Guest count drives the variable 60–70% of the total, which is why the guest list is the budget conversation, and every other decision is a footnote to it.
The category breakdown
Typical US splits: catering ~25%, venue ~18%, photo/video ~12%, attire ~10%, music ~8%, bar ~8%, flowers ~7%, cake/invites/misc the rest. Regional and style shifts move categories (foodie couples push catering to 30%; city weddings push venue), but the shape holds — and the calculator's lines map to how vendor quotes actually arrive.
The style ladder
$75/guest is casual-real (backyard, buffet, talented friend photographing). $160 is the classic mid US wedding. $300+ is upscale (plated dinners, premium bars). $550+ is luxury territory where per-guest lines compound. The ladder is honest about what money buys at each rung — and most couples land one rung lower than their first guess.
