FAQ
Common Questions
How does this coffee quantity calculator for events work?
Our calculator estimates drinks per hour, total guests, and service length to calculate how much coffee, milk, water, ice, and cups you'll need. It's designed specifically as a coffee calculator for mobile coffee business owners and caterers, so you don't have to guess or build spreadsheets for every event.

Yes. If you're figuring out how to start a mobile coffee business, this tool gives you realistic baselines for beans, milk, and cups per event. Use it to build your first menus, set pricing, and avoid underordering on your early bookings.
What are the most common coffee supply mistakes at events?
Underestimating milk quantities (especially alternatives), insufficient water planning, inadequate ice estimates for warm weather events, and forgetting napkins and backup equipment parts.
How do I adjust for different event types?
Corporate events typically see higher coffee consumption in the morning (1.5-2 drinks per person), while weddings and festivals have more spread-out demand (0.8-1.2 drinks per person). Adjust your estimates based on event timing and audience.
Should I bring backup supplies?
Yes! Always bring backup beans, extra cups, and additional milk. A 15% buffer is standard, but consider 20-25% for high-profile events where running out isn't an option.
How do weather conditions affect my supplies?
Hot weather increases iced drink demand by 40-60%, requiring more ice and cold brew supplies. Cold weather boosts hot drink consumption by 20-30%. Always check the forecast and adjust accordingly.
