What is the Average Cost of a Stag Do per Person?

“How much is a stag do, roughly?” is the question every guest asks and every best man dreads, because the honest answer is “it depends” — and the average figures floating around online are almost always lower than what people actually end up spending. Let’s give you real, usable numbers, and more importantly, explain why the true cost is reliably higher than the headline.

The broad averages

If you want a single sentence to anchor expectations: a UK stag typically lands between £150 and £300 per person all-in for a weekend, and a European trip more like £250 to £500 or more once you’ve added flights. But averages are blunt instruments, and the spread within them is enormous. A low-key UK cottage weekend with home-cooked food and a couple of walks can come in well under £150 a head; a two-night Eastern European blowout with activities, nice accommodation and a big kitty can sail past £500. The average is a starting point, not a budget.

What actually drives the number

Four levers move the per-head cost more than anything else:

• Destination. UK versus abroad is the obvious one, but even within the UK, a premium city differs wildly from a rural cottage. Abroad, cheap-beer destinations can offset their flights with low on-the-ground costs.
• Length. A single night out is a fraction of a two- or three-night weekend. Each extra night adds accommodation, food and a fresh kitty.
• Activities. A free walk and a pub is one thing; a track day, a boat, a brewery tour and a meal stack up fast.
• Group size. Counter-intuitively, bigger groups often lower the per-head cost through group rates and the cheap split of covering the groom — while very small groups pay more per person for the same experience.

The hidden extras that inflate the real figure

Here is where best men get caught, and why the “average” misleads. The number people quote is usually the visible cost — the activity price, the accommodation. The real per-head figure includes a whole layer of extras that quietly stack up:

• Covering the groom — his share, split across the paying guests, added to every head.
• Booking and card fees — the small percentages that appear at checkout.
• Transfers and transport — airport runs, the minibus, taxis between venues.
• The kitty — the pooled drinks fund that the headline price never mentions.
• Food not pre-booked — the meals you didn’t plan but everyone needs.
• Contingency — the buffer for the surprises that always come.

Add these and a “£120 activity weekend” is comfortably a £200-a-head weekend in reality. Pretending otherwise just means the gap lands on you or as an awkward top-up ask later.

Build your number, don’t borrow the average

The single most useful shift in mindset: stop asking what the average stag costs and start calculating what *your* stag costs. The average is for setting rough expectations in the first conversation. The figure you put on the invitation should be built from your actual plan — your accommodation quote, your activity prices, your travel, the groom’s split, plus a contingency — divided by your paying guests. That bespoke number is honest; the borrowed average is a guess that will be wrong in one direction or the other.

A high-visibility warning on the gap between the quoted figure and the collected figure: whatever per-head number you land on, the moment you start collecting it you’re holding the group’s money and committing it to bookings. Keep the float transparent and separate from your own current account — a kitty of clustered deposits in and big payments out is exactly the pattern that trips bank fraud and anti-money-laundering checks, and a frozen account while you’re holding two grand of mates’ cash is the last thing you need. Based on internal 2026 transaction data across thousands of group trips, the most common cause of a blown budget isn’t an expensive activity — it’s an underestimated per-head figure quoted early, then quietly topped up late when the hidden extras surface. Quote the real number the first time.

Personal spending money sits on top

One final clarification that prevents arguments: the per-head budget covers the *plan* — accommodation, activities, transport, food, the groom. It does not, and should not pretend to, cover every personal round at the bar all weekend. Make clear to the group that the budget is the cost of the organised weekend, and that everyone brings their own spending money for drinks and extras on top. Conflating the two is how a £200 budget gets remembered as “it ended up costing me £350” — because £150 of that was their own bar tab, not the stag’s cost.

The bottom line

Use the averages — £150–£300 in the UK, £250–£500-plus abroad — to set early expectations, then throw them away and build your group’s real number from the actual plan. Account for the hidden extras that the headline always omits, quote the honest all-in figure on the invitation, keep personal spending money clearly separate, and track the collection transparently. Do that and nobody is ever ambushed by the true cost — which, for a best man, is half the job done.
