Ranges reflect national party-planning guidance for 2025-26: overall reveals span $50 (dessert-only DIY) to $1,500+ (hosted events), with a 36-inch reveal balloon about $9 to fill, both-color powder kits near $100, and budget bloggers documenting full parties just under $100. Only food and favors cost you per head; everything else is a decision you make once.
A reveal is a small party with one expensive second. The calculator breaks it into nine categories so you can see which lines deserve the money — and which are habit rather than choice. Two lines (food, favors) scale with guests; the rest are fixed, so a bigger guest list mostly buys a bigger food bill, not a better reveal.
Total = venue + food × guests + cake + decor + reveal + games + favors × guests + invites + photo. Per guest = total ÷ guests. The marginal-guest figure (food + favors) tells you what each additional invitation actually costs.
Start from the preset closest to your plan, then swap in real quotes. Timing tip baked into the food line: an afternoon party between meals feeds people dessert and drinks at $10-12 a head; a party at noon or 6 p.m. pulls the food line toward $25+ because guests expect a meal.
The hosted preset: 30 guests, a $200 park pavilion or restaurant side room, $15-a-head catered lunch, a $95 reveal cake, $175 of decorations including a small balloon garland, a $110 reveal moment (both-color powder kit plus confetti cannons), $45 of games, $4 favors, $35 of printed invites, no photographer. Total: $1,230, which is $41 a guest. Venue plus food is $650, about 53% of the budget — the same share that dominates every party from baby showers to weddings.
Drop to the backyard preset at 20 guests and the math shrinks fast: home venue, $12-a-head food, $60 grocery reveal cake, $90 of decor, a $45 balloon-and-cannon moment, and the total lands at $520, $26 a head. The showstopper at 45 guests with a $550 venue, $28-a-head food, a pro photographer, and a $240 pro-balloon reveal runs $3,290. All three are normal parties; the difference is mostly three decisions — venue, photographer, and how elaborate the reveal moment is.
One logistical note that saves the day: have the ultrasound tech seal the result in an envelope and hand it directly to the baker or balloon filler. The party stays a surprise for you too, and nobody at your table carries the secret.
Nationally, anywhere from $50 for a dessert-only backyard gathering to $1,500+ for a hosted event, with most parties landing between $300 and $1,200. At typical prices, a backyard reveal for 20 guests runs about $520, a hosted party for 30 about $1,230, and a blowout with a photographer and balloon artist for 45 about $3,290. Guest count moves the total through two lines: food and favors.
Usually the parents-to-be, since a reveal is centered on their news — unlike a baby shower, which a friend or family member traditionally hosts. Plenty of families co-host and split categories instead. If someone offers to throw it for you, let them; the calculator's category breakdown makes an even split by dollars, not vibes, easy to share.
A sealed envelope from your ultrasound tech, a $9 fill for a 36-inch balloon, and a cake baked at home. Done in the backyard with dessert and drinks, the whole thing can land under $100 — the national floor for budget reveals. Confetti poppers at $2-5 apiece and a balloon box are the next-cheapest reveal moments; colored powder kits run near $100 for both colors.
No, and most parties skip one — a friend with a decent phone captures the reaction fine. Book a pro (typically $200-$450 for a short session) only if the reveal doubles as a maternity shoot or family from far away can't attend and will watch the video. The reaction shot matters more than the equipment: put one person in charge of filming the moment and enjoy it yourself.
Please no. Gender-reveal pyrotechnics have started wildfires, caused injuries, and triggered a fatal explosion — the party genre's worst headlines all come from explosive reveals. Balloons, confetti, colored powder in open air, cake fills, and smoke-effect candles deliver the same surprise with none of the risk, and most require no permit. If it burns, explodes, or launches, pick something else.
Combining them is the budget move. A reveal segment adds roughly $100-$250 to a shower's cost (reveal item plus a little extra decor) versus throwing a second event with its own venue, food, and invitations. Guests also tend to prefer one party in a busy season. Split parties make sense mainly when the shower is a traditional no-men event and the reveal is meant for the whole family.
