The most profitable school fair stalls (by margin, not folklore)

Every fair committee has its folklore about which stalls "do well". Takings and profit aren't the same thing, though — the BBQ takes the most money at half the fairs in Britain while making less than the tombola. The clean way to see it: stalls fall into three margin families.

Family one: donated stock (margins near 100%)

Tombola, bottle stall, cake stall, second-hand books and uniform — the stock arrives free from families, so nearly every pound taken is profit. These are the engine of fair profit, and their real cost is asking: the donation drive in the weeks before decides the stall's takings ceiling. A £200-takings tombola with £15 of tickets and prizes-topping-up beats almost anything else on the field, and scales with how well the request letter worked.

Family two: games (tiny per-go costs)

Splat the rat, hook a duck, penalty shootout, guess-the-sweets — equipment is owned or built once, prizes cost pence per winner, and each go is 50p–£1 of nearly pure margin. Individually small, collectively significant, and they're what makes the fair feel like a fair. The lever here is throughput: a game a six-year-old finishes in twenty seconds out-earns a fiddly one four times over at the same price.

Family three: the crowd-pleasers with real costs

BBQ (stock, gas, and the person who knows food hygiene), bouncy castle (hire fee eats the first ~90 goes), face painting (paid artist or a volunteer with actual skill), refreshments (stock plus urn logistics). These can profit well — but they're the stalls where optimistic "expected gos" quietly turn projected profit negative, and where last year's actual numbers matter most. They earn their place partly as footfall anchors: the BBQ smell sells tombola tickets.

Balance, then check the maths

A good fair needs all three families — all-games is a fete without lunch, all-BBQ is a car park with a queue. The planning discipline is just honesty per stall: real costs, realistic gos (last year, not hope), and someone willing to say "the candy floss machine hire has never once paid for itself".

Do the honesty in one table: the free PTA Fair Profit Planner starts with a typical fair and updates projected profit as you edit — export the CSV for the treasurer when the committee's happy.
