WEDDING & EVENTS Calculators

Calcshark’s wedding and event calculators take the stress out of planning logistics. Work out how much alcohol to buy, guest and catering quantities, budgets, and timelines — all free and instant.

Events live and die by quantities and budgets. These tools turn your guest count into the bottles, portions, and pounds you need, so you neither run short nor overspend.

Estimating drinks and food for a crowd is genuinely hard — a small error per guest multiplies across a long event. A wedding alcohol calculator gets the quantities right based on guests, duration, and preferences.

Clear quantities and budgets prevent last-minute shortages and overspending, and make supplier conversations much easier.
