Small + nicer or large + simpler? The math, side by side.

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?

Scenarios
STAGE 1 OF 4

Budget & guest-count range

The headline trade-off math. Defaults reflect a typical mid-budget US wedding scenario.

All-in spend you're working with. Typical: $25K-$150K. The tool will show what each guest count looks like at this budget.
$
Where you are now. Will be highlighted in the scenario table.
Smallest you'd consider — intimate family + closest friends. Typical floor: 30-60.
Maximum you'd seriously consider. Typical ceiling: 200-300.
Drives variable per-guest cost defaults. HCOL: $200-300+. MCOL: $130-200. LCOL: $80-150.
Drives ~$25-60 per-guest swing. Affects variable cost defaults.
The insight this tool surfaces. Most couples assume guest count is roughly linear — double the guests, double the cost. It isn't. At low guest counts you're paying fixed-cost overhead per guest. At high counts variable costs dominate, and the marginal cost of guest #200 is far higher than the headline-average suggests. The right guest count isn't "how many can we fit" — it's where the per-guest experience dollar peaks.
STAGE 2 OF 4

Fixed costs

The costs that don't scale with guest count. These dominate per-guest at low headcounts and dilute as you scale up.

Same whether you have 50 or 250 guests (assuming room fits). HCOL: $10-25K. MCOL: $5-15K. LCOL: $2-8K.
$
Photographer hours don't change with guest count. Typical $3-8K.
$
Dress, suit, alterations, shoes, accessories, hair/makeup day-of. Fixed across guest count. $2-6K typical.
$
Personal florals (bouquet, boutonnieres), ceremony arch, signage. Centerpieces are variable — counted separately.
$
DJ or band cost is fixed across 50-250 guest range. $1.5-8K typical.
$
Day-of: $1.5-3K. Month-of partial: $3-6K. Full-service: 10-15% of total (not used here).
$
Marriage license, day-of insurance, officiant fee, transportation for couple, hair/makeup trials. Typical $1-2K.
$
Pre-events that are largely fixed even if guest count scales. $1-3K typical.
$
The fixed-cost floor. Whether you have 50 or 250 guests, this number doesn't change. It's the "you must spend at least this much to have a wedding at all" baseline. Dividing it across guests is what makes 50-person weddings look expensive per-head — but the dollar-per-guest-experience can still be higher because the variable spend per guest is higher.
STAGE 3 OF 4

Variable per-guest cost

Everything that scales linearly with head count. Catering, bar, favor, place setting, invitation. Defaults pull from region + bar service.

Fully loaded — what each plate actually costs after the 22% service charge and 18% gratuity stack and tax. HCOL: $180-300. MCOL: $120-200. LCOL: $70-140.
$
Open bar premium: $50-85. Beer + wine: $25-40. Cash bar: $0.
$
Often left on the table. Welcome bags higher-leverage. $5-25 typical.
$
If venue doesn't include. Chair upgrades, charger plates, premium linens. $8-25 typical.
$
Suite + save-the-date + RSVP + thank-you postage. $4-12 per guest fully loaded.
$
Centerpieces scale with table count, which scales with guests. $15-50 per guest typical.
$
The variable-cost reality. Adding one more guest at HCOL is often $250-$320 in true marginal cost. That's the math couples skip when their mother says "we have to invite the cousins." Five cousins = $1,500. Twenty cousins = $6,000. The right answer is sometimes yes — but it should be a deliberate spend decision, not a default.
