Wedding costs split cleanly into two buckets: fixed (venue, photo, dress, flowers, planner — same whether 50 or 250 guests) and variable (catering, bar, favor, place setting — scales linearly with head count). At 50 guests the fixed costs dominate per-guest. At 250 the variable costs do. The cross-over math nobody runs before sending invites: which guest count actually maximizes the dollars spent on guest experience?
The headline trade-off math. Defaults reflect a typical mid-budget US wedding scenario.
The costs that don't scale with guest count. These dominate per-guest at low headcounts and dilute as you scale up.
Everything that scales linearly with head count. Catering, bar, favor, place setting, invitation. Defaults pull from region + bar service.
