How to calculate
a stall fee

The stall fee is the one number that decides whether your day washes its face, and whether your sellers come back next year. Get it wrong in one direction and you are out of pocket. Get it wrong in the other and your sellers quietly do not apply again. This is how to work it out properly, what it has to cover, and the two checks to run before you publish it.

Start here, the principle
A stall fee is what a seller pays for a chance at your crowd.

That is the whole of it. It is not a membership, it is not a donation, and it is not a way of balancing a budget that does not balance.

Which means the fee never rises to cover a thin day. If fewer people are coming than you hoped, raising the fee charges sellers more for less. It is the first thing a spreadsheet suggests and it is the wrong direction every time.

And the money is not yours until the day runs. If the day does not go ahead, every stall fee goes back, in full. Same for entry fees. Hold it, do not spend it on a venue deposit and hope.

There is always a stall fee. Even a community day with free entry charges something, because a fee of nothing tells a seller the spot is worth nothing, and a seller who paid turns up.

The formula
Total costs, including contingency
minusAll income that is not stall fees
divided byStalls expected to trade
= your break even fee

Everything else in this guide is either working out one of those three numbers properly, or deciding what to do once you have the answer.

Step one  ·  total your costs

Work through every group. Most days do not need every line, but the lines people forget are almost always in Compliance, Safety and Admin.

GroupWhat sits in it
VenueHire fee, bond or deposit, extra hours, key or access fee, cleaning fee, damage excess
ComplianceCouncil event application, temporary food premises permit, public liability insurance, traffic management plan, noise or amplification permit
AmenitiesPortable toilets and servicing, hand wash stations, drinking water, bins and waste collection, cleaning crew
SafetyFirst aid officer or service, first aid kit, fire extinguishers, security, RCD testing, high visibility vests
SiteMarquee hire, table and chair hire, generator and fuel, extension leads, fencing, matting
AtmosphereEntertainment or musicians, PA hire, kids activities, decorations
Food and drinkCatering for volunteers, coffee cart minimum spend, urn and cups, ice, esky hire
Signage and printBanners, A-frames, bunting, stall number cards, seller lapel badges, site maps, directional signs, flyers, posters
MarketingBoosted posts, local paper or radio, flyer distribution, a photographer
AdminChange for the float, EFTPOS hire, card processing fees, stationery, postage, fuel and travel, volunteer thank yous
PackdownCleaning crew if separate, waste removal, any make good on the venue
ContingencyA percentage of everything above. See the next section
Three that catch people out.

Card processing is a real cost and it is not small. Roughly 1.75% plus 30 cents a transaction. Three hundred transactions is about $150 before you have sold anything. Work it from your expected transaction count, not as an afterthought.

The float is not a cost. It is money you draw out and bank back the same afternoon. Book it as a movement with two dates, never as an expense, or your day permanently records spending money it got back.

Cash paid out on the day needs its own line. Every day with a tin has an afternoon where somebody pays someone forty dollars out of it. Two names, a reason, the amount, a signature.

Step two  ·  add contingency

Ten percent is the default and it is the line first time organisers leave out. It is the one that decides whether anybody ends up out of pocket.

Take it off cash cost lines only. Exclude anything donated and anything marked not applicable. Ten percent of a donated hall is a contingency against a risk nobody is carrying, and it quietly inflates your fee for no reason.

Cash cost lines$2,888
Excluded: donated venue $450, donated prizes $180, two lines not applicable$0
Contingency at 10%$289
Step three  ·  subtract everything that is not a stall fee

Every dollar here is a dollar your sellers do not have to carry.

IncomeNote
Ticket or entry salesBy type, live. If entry is free this is zero, and your sellers are carrying the day. Say so out loud, see the fairness check
DonationsThe donate button on your public page
SponsorshipShow cash and in kind separately. In kind reduces a cost, it does not add income
GrantsWith their acquittal date, because that is work you are taking on
Your own cateringOnly the margin, not the turnover
Raffle or door prizeNet of the cost of the prize, if you bought it
Step four  ·  divide by stalls expected to trade

This is where most calculations go wrong. There are four different counts and only one of them belongs in the sum.

CountUse it for
Invitations sentNothing financial. It is a marketing number
Applications receivedNothing financial. It tells you your reach, not your income
Stalls acceptedThe starting point, and the only one most people use
Stalls expected to tradeThis is the one. Accepted, minus your no-show rate
Twenty eight accepted with a ten percent no-show rate is twenty five stalls expected to trade. If you divide by twenty eight you have quietly under-priced your day by eleven percent, and you will not find out until the morning.
Step five  ·  choose your position
PositionFeeWhat it means
Free$0You fund the gap yourself. Know the number before you decide, not after
Break evenThe figureThe day washes its face. No surplus, no shortfall, no room for anything going wrong
BufferedFigure plus marginCovers your no-show rate and gives you something to absorb a surprise. This is the sensible default

A buffered fee is not profiteering. It is the difference between a day that survives one supplier letting you down and a day that does not.

What you are actually charging for

The standard stall is 3m x 3m. That is a 10ft by 10ft plot, and it is the standard because it is the footprint of the pop up gazebo almost every seller already owns. Draw your site plan in 3m squares and most sellers will arrive with something that fits.

Stall typeSpaceWhat it is for
Stock stall3m x 3mThe standard. Anything selling physical product off tables or racks
Food or drink3m x 3m minimum, often 3m x 6mNeeds room behind for prep, a hand wash station, and somewhere to stand that is not in front of a hot surface. Compliance gated
Service or booking3m x 3m, screened or corneredMassage, hair, photography. Anything where somebody sits still and would rather not be watched
Pre loved3m x 3m, or a car boot baySecond hand, clear outs, trash and treasure
Workshop stall2m x 3m, or 3m x 3m with depthA display at the front and three or four stools behind, where the seller teaches a fifteen minute thing
Awareness or lead stall3m x 3m, or 2m x 2m indoorsA website, an app, a local service, a trade. Nothing sold on the day. They are collecting names, not taking money
Small or information stallOne trestle, about 1.8m x 0.8m, in 2m x 2mA community group, a sign up table, a raffle table. It does not need a gazebo
Community or not for profitUsually 3m x 3m, often a trestleA school club, a charity, a local group. Present rather than selling, and priced at or near nothing
Showcase spotA share of one long tableNot a stall. A seller from afar who is not there in person
Unmanned brochure slotAbout 30cm on a shared tableA physical presence with nobody standing there. A brochure holder, a card stack, a sign with a code. Minded by a volunteer
The awareness stall is the one that changes who can come.

Every other type on this list assumes somebody selling something. An awareness stall lets a trade, a service or a local organisation take a spot without pretending to be a market seller. They pay for the crowd, the same as everyone else, and they should be priced accordingly.

Setting the tiers

Set one base fee and express every other tier as a ratio of it. That way, when your costs move, you change one number and every tier moves with it. Working out six separate prices by hand is how tiers drift out of proportion.

TierSuggestedWhy
Stock stall, 3m x 3mBase, 1.0Everything else is priced against this
Pre loved, service, workshop1.0Same footprint, same access to the crowd
Food or drink with power1.4 to 1.6More space, more power, more compliance handling, and usually the highest takings of the day
Double site, 3m x 6m2.0Two plots is two plots
Awareness or lead stall0.8Full footprint but no takings on the day. Still paying for the crowd
Small or information, 2m x 2m0.6Less space, less prominence
Showcase spot0.4A share of a table, and nobody standing there
Unmanned brochure slot0.25Thirty centimetres and a volunteer's attention
Community or not for profit0, or near itThey are part of why people come. Charge nothing, or a token
Early bird0.85With a real cutoff date. It buys you certainty early, which is worth the discount

The ratios above are a starting point, not a rule. Adjust them to your day, then keep them fixed across tiers so nobody can argue they were treated differently.

Per seller overrides exist and should be recorded on the invitation, not agreed in a message and remembered. If you waive a fee for someone, the day's income projection has to know.

Break even fee, $830 divided by 25$33
Buffered, plus 15%$38

With a base of $38, a food stall with power is $57, a 2m x 2m information stall is $23, a showcase spot is $15, and a community group pays nothing. Every one of those moves automatically the next time a cost changes.

The fairness check, which is not optional

A seller needs to take roughly five times the fee before the day feels worth doing, once they have counted their stock, their fuel and a whole day of their life. Run the number before you publish.

At $38 a stall, a seller needs to take about $190 to feel this was worth doing. Is that realistic for the kind of stalls you are inviting?

And where entry is free, turn it around and say the quiet part out loud:

At $38 a stall with free entry, each seller is paying for about 190 visitors through the door. Entry is free because the stalls paid for it.

A seller will ask why they pay when the shoppers do not. Have the answer ready rather than improvising it on the day.

A fairness question with nothing to do about it is a rhetorical question.

If the answer is "that is a stretch", there are only ever three levers. Pull one, do not raise the fee.

1. Drop the fee. Work out what the shortfall is and what would cover it. Dropping $38 to $32 across 25 stalls costs $150, which is about twenty more people through the gate.

2. Add non stall income. A small entry fee, a raffle, one sponsor, a donate button. Every dollar here comes straight off the stall fee.

3. Cut a cost line. Look at your biggest three. Marquee hire when the hall has trestles is the classic one.

Tell the seller the same arithmetic

Put the honest numbers on the application: how many people the day expects, how many stalls, and what that means per stall.

A seller who takes a stall knowing it is a small first year day is a seller who came in with their eyes open, priced their stock for it, and is not angry afterwards. A seller who was told it would be busy is a seller you have lost, and they were the one who could have brought three more next year.

If there is anything left over
Market Day Collective takes 25% of whatever is left at the end.

Nothing if there is nothing. It is a real call on the surplus, so put it in your sums while you are sketching rather than discovering it at close.

Before you publish the fee

1 Divide by stalls expected to trade, not stalls accepted

The single most common error, and it under-prices the day by exactly your no-show rate.

2 Run the times five check and answer it honestly

If it is a stretch, pull one of the three levers. Do not publish and hope.

3 Put the real numbers on the seller application

Expected attendance, stall count, and visitors per stall. Sellers who know what they are buying come back.

4 Remember whose money it is

Not yours until the day runs. If it does not happen, every fee goes back in full.
