The food shopping list provides specific quantities for each item you need to purchase or prepare.

Cost estimates are based on typical grocery store prices. Actual costs may vary based on your location and where you shop.

The planning timeline helps you stay organized leading up to the party, ensuring nothing is forgotten at the last minute.

Costs vary enormously depending on whether you host at home or book a venue, and how many guests you invite. Here are realistic ranges based on party type:

The biggest variable is labour. If you cook everything yourself, you can feed 40 guests for around £120-£180. Hiring a caterer for the same number adds £300-£600 on top. For most home parties, the food bill lands between £5 and £12 per person when you shop and cook yourself.

Don't forget one-off costs: a graduation cake for 40 people runs £40-£80 from a supermarket, or £80-£180 from a bakery. Balloons, banners, and table decorations add another £20-£60. If you hire a marquee or gazebo, budget £80-£200 on top.

Getting quantities right is the most practical part of party planning. Too little and you're embarrassed; too much and you've wasted money. These figures are for an open house where guests arrive and leave over 2-3 hours, not a sit-down meal.

Add 15% to all quantities as a buffer. If you have an afternoon open house (2-5pm), guests usually eat less than at a lunchtime event because many will have eaten before arriving. Conversely, an evening party expects more substantial food. Always have a mix of hot and cold options, and label anything with allergens clearly.

Where you host changes almost everything about quantities and costs. Here is what to adjust depending on your setup.

A hybrid approach is common: set up food and drinks indoors with overflow seating in the garden or patio. This gives guests options and spreads the crowd so the space does not feel cramped. If weather is uncertain, have a backup plan for moving the drinks station inside.

Knowing your per-head cost makes it easy to scale up or down as the guest list changes. These figures assume you are cooking and setting up yourself. Hiring a caterer adds roughly £8-£15 per person on top.

The biggest cost saver is doing it yourself. A DIY BBQ for 40 people costs roughly £400-£640 in food and drinks. The same guest count at a mid-range caterer runs £800-£1,200. If budget is tight, focus on one or two crowd-pleasing mains (pulled pork, taco bar) rather than spreading thin across many dishes.

Graduation season often coincides with first job offers and repayment letters. A quick 15-minute numbers check now can save real money over the next 12 months.
