Catering Budget Calculator — Food & Drink Costs
Budget for food and drink costs per head for any party or event.
How We Calculate This
This calculator estimates total catering costs from per-head food and drink rates plus fixed costs, then adds a service charge, optional gratuity and a contingency buffer.
Formula
- Food total = food cost per head × guests
- Drinks total = drinks cost per head × guests
- Subtotal = food + drinks + staff + equipment hire
- Total catering = subtotal × (1 + service charge% + gratuity% + contingency%)
- Cost per head = total catering ÷ guests
- Budget remaining = your budget − total catering
Defaults applied in Advanced Options: 12.5% service charge (the UK convention for waited catering), 0% gratuity and a 5% contingency buffer. Leave Food Cost per Head blank to use a typical UK rate for your chosen service style (self-catered ≈ £8, catered buffet ≈ £22, sit-down ≈ £42, canapés ≈ £14 per head).
