Taking the guesswork out of party planning with data-driven calculations
We've all been there. You're hosting a party, excited to celebrate with friends and family, but that nagging question keeps you up at night: "How much food do I actually need?"
I learned this the hard way when I hosted a backyard BBQ for 30 people. I bought enough burgers for an army, but ran out of drinks by hour two. Another time, I had leftover birthday cake for weeks. The internet was full of conflicting advice, complicated formulas, and generic rules of thumb that never quite fit my specific party.
That's why I built No Missed Steaks. A simple, science-backed calculator that does the math for you—so you can focus on what matters: enjoying your party and making memories with the people you love.
Our starting point is industry-standard serving sizes from professional catering guides and USDA nutritional data. These are the same portions caterers use when planning events.

Our calculations are based on industry-standard serving sizes from professional catering guides and adjusted using real-world party data. That said, every crowd is different! Consider these results as guidelines and adjust based on your specific knowledge of your guests. Know they're big eaters? Round up. Have vegetarian guests? Adjust protein quantities accordingly.
We recommend having 10-15% extra on hand for unexpected guests or hearty appetites.
Currently, the calculator provides baseline quantities for each party type. We recommend using these as your starting point and adjusting based on:
Pro tip: Print or screenshot your shopping list and make notes directly on it!
Our calculator provides quantity guidelines that work for most standard parties. For specific dietary needs:
The quantities will remain accurate—just swap the specific items to match your menu!
