One address for everything: [email protected]. We read every message. Simple questions get a reply within a couple of business days; error reports usually get a reply the same day, because they matter most.

Reporting an error

If a calculator gives a result you believe is wrong, we want to know. The most useful report includes:

• Which calculator, and which tab or mode you were on.
• The exact inputs — guest count, hours, adults and kids, whatever you entered.
• The result you got and what you expected, with your reasoning or source if you have one. "My caterer says 8 ounces, you say 6" is a perfectly good report.

What happens next: we reproduce it, check the formula against its cited references, and either fix it or write back explaining which convention the calculator follows and why. Verified fixes ship within days and the review date on the page is updated.

Requesting a calculator

Tell us what you're trying to work out and what you'd do with the answer. "How much punch for a baby shower of 30 with kids" is far more useful to us than "a punch calculator." We build the ones with real demand first, and every one is free once it exists.

Putting a calculator on your site

Event rental companies, venues, caterers, bakeries, and party blogs are welcome to embed any calculator on their own pages at no cost — one line of HTML, no signup, no key. Details are on the embed page. If your inventory or portions differ from the defaults — your tent sizes, your serving sizes — ask; we've adjusted calculators to match a partner's real catalog before, and it usually takes a day.

What we can't help with

We don't plan events, recommend vendors, or sell anything. The calculators tell you how much to buy for the crowd you describe; they can't tell you who's coming, and they aren't a substitute for a caterer's final headcount or your local health department's rules if you're serving the public.

Press and partnerships

Same address. We're happy to explain how any calculator works, share the serving rates and sources behind a number, or talk about what's being built next.
