Vendor Fee Calculator: How Much to Charge Vendors

Enter the event costs you want vendors to cover, how many food, craft, nonprofit and commercial vendors you expect and what they sell, and compare a flat fee, a percentage of sales and a flat fee plus a percentage.

Work Out Your Vendor Fees

Costs and fee models

Event costs you want vendor fees to cover, not your whole budget.

For the percentage-of-sales model.

Charged on top of a smaller flat fee in the combined model.

Fees above this share of a vendor's sales are flagged.

Discounts and add-ons

Off nonprofit fees in every model.

Off the flat part for vendors who book early.

Share of vendors you expect to book early.

Per hookup, priced to cover your power costs.

Food and drink

Food trucks, food booths and drink vendors. They use more space, power and water, so they often pay more.

Vendor revenue with flat fees

101.9% of your $15,000 costs from 66 vendors, plus $900 from 18 power hookups.

Flat fee recovers

$15,281 in fees.

68.6%

% of sales recovers

$10,287 in fees.

101.2%

Flat + % recovers

$15,182 in fees.

A percentage of sales alone needs 15.5% to cover your costs.

The formula

Costs ÷ (vendors × fee weight, less discounts) = flat fee for a weight of 1, rounded up to the next $5.
Expected sales × rate = percentage fee.
Combined: the percentage first, then a flat fee sized to cover the rest.

Planning estimate only. The defaults are planning assumptions, not market rates: check what comparable events near you charge and ask your vendors what they can carry.

Fee per Vendor Type, by Model

Each fee is for one vendor at its expected sales, with the share of those sales it takes. Fees over your affordability flag are marked.

How the Vendor Fee Calculator Works

  1. 1. Decide what vendors should cover

    List the costs of the event: site, tents, security, waste, marketing and staff. Take off what tickets and sponsors pay for, and the rest is what vendor fees need to recover.

  2. 2. Count vendors by type

    Food, craft and retail, nonprofit, and sponsor or commercial vendors use different space and power and sell different amounts, so each gets its own count, sales estimate and fee weight.

  3. 3. Compare three fee models

    The calculator sizes a flat fee, a percentage of sales and a flat fee plus a percentage against the same costs, after nonprofit and early-bird discounts, and shows how much of the costs each one recovers.

  4. 4. Check what vendors can carry

    Each fee is shown as a share of that vendor’s expected sales and flagged above your threshold. A fee that eats a large share of a vendor’s takings will cost you vendors next year.

  5. 5. Publish the fees with your application

    Put the fee schedule, the deadlines and any percentage reporting rules in your vendor application form and your vendor agreement.

Flat Fee vs Percentage of Sales

How the three vendor fee models compare. Many events mix them, for example a flat fee for craft vendors and a flat fee plus a percentage for food vendors.

ModelHow it worksWorks best forWatch out for
Flat feeEvery vendor of a type pays the same price up front, usually with early-bird and nonprofit rates.Small and mid-size markets and fairs, craft shows, and any event that needs the money before the day.Takes the same from a vendor who has a slow day, so check it against their expected sales.
% of salesEach vendor pays a share of what they sell, reported and paid after the event.Large festivals and fairs with proven sales, where vendors will accept sharing a good day.You are paid late, must check reported sales, and get nothing from vendors who sell nothing on site.
Flat + %A smaller flat fee up front covers your fixed costs, and a percentage of sales follows the event.Food courts and festivals with fixed costs to cover and big swings in sales.Two charges to explain and settle. Write both into the vendor agreement.

Pricing Trade Show Booths Instead?

This calculator is for markets, fairs and festivals where vendors sell to the public. For a trade show or expo rate card priced by booth size and position, use the exhibitor booth pricing calculator. To decide who gets a space at a juried show, see our craft show jury criteria.

Sell Vendor Spaces From Your Market Map

Map D sells vendor spaces at flat prices from a map vendors can book. With vendor fair software you set booth types for food, craft and nonprofit spaces, each with its own price, add dated early-bird prices, sell power as an add-on with limited inventory and approve each vendor before they pay; see booth sales software for checkout and payments. Map D doesn’t collect a percentage of vendors’ sales. You can build one event’s map free; publishing it needs a paid plan, from $1,500 per event, and selling booths online is from $2,500 per event.

What this assumes

Every figure the calculator starts with, and where it comes from. Where the honest answer is that a number depends on your venue, it says so rather than inventing one.

Costs to recover
The event costs you want vendor fees to cover, such as site rent, tents, security, waste, marketing and staff. Enter the share you expect vendors to pay, not your whole budget, if tickets or sponsors cover the rest. The default $15,000 is an example.
Fee weights
How many flat fees each type pays compared with a craft and retail vendor. The defaults (food 2, craft 1, nonprofit 1, sponsor and commercial 1.5) are planning assumptions that reflect the extra space, power and water food vendors usually use. Set them to match your own price list.
Expected sales per vendor
What one vendor of each type expects to take over the whole event. Ask returning vendors or use last year's sales reports. The defaults ($3,000 food, $1,200 craft, $300 nonprofit, $0 commercial) are examples, not benchmarks.
Percentage rates
The percentage model charges 10% of sales and the combined model 5% on top of a smaller flat fee. Both are editable starting points. A type with no on-site sales, such as a bank or solar company, would pay nothing under a percentage, so it pays its flat fee instead.
Discounts
Nonprofits get 50% off in every model. Early birds get 10% off the flat part, and the calculator assumes half your vendors book early; the list price is raised to cover it. A percentage is settled after the event, so it has no early-bird price.
Rounding
Flat fees are rounded up to the next $5 so they read as prices, which is why revenue lands slightly above 100% of costs.
Electricity add-on
Power hookups are an add-on at $50 each by default, priced to cover your generator or electrician. They are added to total vendor revenue but not counted towards the costs to recover.
Affordability check
A fee above 20% of a vendor's expected sales is flagged. The threshold is this calculator's planning assumption, not a standard; ask your vendors what they can carry.

What it does not model

  • What comparable markets, fairs and festivals near you charge, which in practice sets your ceiling. Check their published vendor fees before you set yours.
  • Application and jury fees, security deposits and late or no-show penalties.
  • Booth size and location premiums within a type, such as corner or double spaces. Use separate types or the exhibitor pricing calculator for a booth rate card.
  • Sales tax, health permits and temporary food licences, which vendors usually arrange with your city or county.
  • How you verify reported sales under a percentage model. Settle the method, the deadline and the audit right in your vendor agreement.

Frequently asked questions

How much should I charge vendors at an event?

Start from the costs you want vendors to cover, divide them by your vendors, weighted so food vendors pay more than craft vendors, and check the result against what each vendor expects to sell. If a fee is a large share of a vendor's sales, lower it, give that type a discount or cover more of the costs from tickets or sponsors.

Should I charge vendors a flat fee or a percentage of sales?

A flat fee is simple, paid up front and certain, but it takes the same from a vendor who has a slow day. A percentage of sales shares the risk with vendors, but you get paid after the event and have to trust or check reported sales, and vendors who sell little pay little. A small flat fee plus a percentage is a middle path: the flat part covers your fixed costs and the percentage grows with a good event.

How much should I charge a food truck vendor?

Food vendors often pay more than craft vendors because they need more space, power, water and grease and waste disposal, and they usually sell more. This calculator's default weight of 2 charges food vendors twice the craft fee. That is a planning assumption: set the weight from what comparable events near you charge and from what your food vendors expect to sell.

What is the difference between this and the exhibitor pricing calculator?

Use the exhibitor pricing calculator for a trade show or expo booth rate card, where the price depends on booth size and position and exhibitors are not selling goods on site. Use this vendor fee calculator for markets, craft fairs and festivals, where vendors sell to the public and you are choosing between flat fees and a share of sales.

Can Map D collect vendor fees?

Map D sells vendor spaces at flat prices. You can set booth types for food, craft and nonprofit spaces, each with its own price, add dated early-bird prices, sell power as an add-on with limited inventory and approve each vendor before they pay. It doesn't collect a percentage of vendors' sales; settle that yourself after the event. You can build one event's map free; publishing it needs a paid plan from $1,500 per event, and selling booths online is from $2,500 per event.
