Most coffee carts undercharge. Not by 5 percent, by 30 to 40 percent. The reason is almost always the same: they price the drink instead of the event. The 2026 answer is per-guest pricing, $8 to $15 per guest, $500 to $2,500 per event, with a separate service fee on top. This guide walks the math, the regional ranges, the line items every quote needs, and three pricing mistakes that quietly eat a season's profit.
The short answer: $8 to $15 per guest, $500 to $2,500 per event
This is the 2026 range across event types, regions, and operator tiers. Use it as a sanity check, then build the actual quote line by line.
| Event type | Per guest | Service fee | Total for 100 guests |
|---|---|---|---|
| Office meeting / pop-up | $6 to $9 | $200 to $400 | $800 to $1,300 |
| Corporate event | $8 to $12 | $400 to $700 | $1,200 to $1,900 |
| Private party | $9 to $13 | $400 to $700 | $1,300 to $2,000 |
| Wedding | $11 to $15 | $500 to $900 | $1,600 to $2,400 |
| Festival / market | Per-drink retail | Booth fee + minimum | Variable |
Plug your specific event into the pricing calculatorto back-solve from your costs. The number you land on should clear at least 45 percent net margin; 60 percent is where the strong operators sit.
Why per-guest pricing beats per-drink pricing
Per-drink looks honest. It is not. Three problems:
- Clients hate it. "Open bar but for coffee" is the mental model couples want. They want a flat number, not a running tab.
- It punishes the operator on slow events. If you charge $6 per drink and the participation rate drops from the expected 80 percent to 60 percent, you eat the difference. Per-guest pricing locks in your revenue.
- It encourages bad guest behavior. Guests counting drinks because they know each one is being tracked changes the room. Bad for your client's event vibe.
Per-guest pricing solves all three. The client gets a fixed cost they can budget against. You get guaranteed revenue regardless of who actually drinks what. Guests order without thinking about it, which means they order more, which means your repeat business goes up.
Pricing by event type
Weddings (highest)
$11 to $15 per guest. Three-hour minimum service. Participation runs 80 percent or higher because the schedule has built-in coffee moments (cocktail hour transition, late reception, send-off). Add a $500+ service fee for the barista hours, custom signage, and the inevitable signature drink. A 150-guest wedding should clear $1,900 to $2,800 in total revenue.
Corporate
$8 to $12 per guest. Shorter service windows (2 hours typical), more drip and americano than specialty, lower add-on potential. Add a flat service fee of $400 to $700. Repeat business is the win here: a corporate client booking monthly is worth a wedding every quarter.
Private parties
$9 to $13 per guest. Birthdays, anniversaries, baby showers, holiday parties. Behave like weddings on participation rate but at lower drink complexity. Service fee $400 to $700.
Markets and festivals
Different model entirely. Per-drink retail pricing ($5 to $8 per drink), booth fee paid to organizer ($100 to $800), and a minimum revenue target before you commit. Walk away from any market where projected revenue is under $1,500 for an 8-hour day. It is not worth the labor.
The 6 line items every quote needs
- Per-guest beverage price. Drinks, milk options, syrups, all included. Flat per-guest number.
- Service fee. Barista hours, setup, breakdown. Separate from per-guest.
- Travel. $0 to 20 miles free, $2 to $4 per mile beyond. Always quoted.
- Add-ons. Signature drink design, custom menu boards, late-night service, second barista.
- Minimum charge. $500 floor on any event, $650 to $850 for most operators.
- Deposit + cancellation. Per your event deposit policy and cancellation policy.
Quotes missing any of these six routinely get pushed below margin. Build a template that has all six and never deviate.
Travel, minimum, add-ons, overtime
- Travel: First 20 miles free, $2.50/mile thereafter. Round trip. Some operators charge $0 to 15 miles, $3/mile beyond; either works.
- Minimum: $500 floor, no exceptions. Below that, your fixed overhead (fuel, loading, permits amortized) makes the event a money-loser.
- Add-ons: Signature drink with custom name ($75 to $150), custom menu board ($60 to $120), late-night espresso bar ($300 to $500), second barista ($45 to $65/hr).
- Overtime: $75 to $125 per additional hour beyond contracted service window. Charge it, do not absorb it.
Deposit + cancellation policy
Standard structure: 50 percent deposit on signing, balance due 7 days before event. Cancellation: 60+ days out, 100 percent refund minus a $100 admin fee; 30 to 59 days, 50 percent refund; 14 to 29 days, deposit forfeit; 13 days or less, full balance owed.
Full template language at event deposit policy and catering cancellation policy. Use it. Operators who book without a written policy lose roughly one event a year to a late cancel, which is $1,000+ on the floor.
When to walk away from a job (margin math)
Run every quote through the profit margin calculator. The math you want to see:
- Gross revenue: per-guest x guests + service fee + travel + add-ons
- Variable cost: ingredients per drink x expected drinks
- Fixed event cost: fuel + loading time + per-event overhead amortization
- Net margin %: (gross - variable - fixed) / gross
If net margin is under 35 percent, reprice or walk. Under 45 percent and you are not scaling, you are surviving. Strong operators sit at 55 to 65 percent net per event, which is what lets the business pay you a real salary and have something left for equipment upgrades.
A worked example: a 150-guest wedding
Mid-range venue, Austin TX, 4-hour reception, 25 miles from commissary, oat milk included, one signature drink request.
- Per-guest: $12 x 150 = $1,800
- Service fee (4 hours): $600
- Travel (25 miles, 5 over the free 20): $25
- Signature drink design: $100
- Custom menu board: $80
- Total quote: $2,605
Now the cost side:
- Expected drinks: 80% x 150 + 40% refill = 180 drinks
- All-in cost per drink: $1.90 x 180 = $342
- Fuel for 50-mile round trip: $18
- Loading + setup + breakdown labor (4 hrs at $25/hr): $100
- Total event cost: $460
Net margin: ($2,605 - $460) / $2,605 = 82 percent. That is what a well-priced wedding looks like. Operators undercharging will book the same wedding for $1,500 to $1,800 and net 60 percent, leaving roughly $700 on the table per event.
Three pricing mistakes that cost real money
- Quoting per drink because the client asked. Hold the line. Per-guest is the right structure. Explain it once, send the quote, move on.
- Forgetting the service fee. Operators routinely build $10 per guest and call that the quote. That is just beverage revenue. The barista hours, setup, breakdown, custom signage, those are not free. Always two lines: beverage + service.
- Discounting to close. If a client says "can you do $9 instead of $12?", the answer is rarely yes. The right answer is "here is what we can remove to hit that number: oat milk, signature drink, fourth hour." Trade scope, do not trade price.
FAQ
What is the going rate for coffee cart catering in 2026?
$8 to $15 per guest depending on event type, plus a $400 to $900 service fee for the barista hours. Weddings sit at the top of the range, office pop-ups at the bottom. A 100-guest event typically lands at $1,200 to $2,000 total.
Should you charge tax?
In most states yes, on the beverage portion of the quote, sometimes on service fees depending on the state. Check your state department of revenue rules. Add it as a separate line on the quote so the client sees the breakdown clearly.
Do you charge for travel?
Yes, beyond a free radius. Standard is 20 miles free, $2 to $4 per mile beyond. Always round trip. Always quoted in writing.
What is the minimum for a coffee cart event?
$500 floor. Most operators sit at $650 to $850. Below $500 and your fixed costs eat the margin, no matter how many guests show up.
How do you charge for a 4-hour wedding versus a 2-hour wedding?
Service fee scales with hours, beverage per-guest does not. For a 4-hour wedding, the service fee is roughly 1.7x the 2-hour rate. The per-guest stays the same.
Do clients tip the coffee cart?
At weddings and private events, often yes, $50 to $300 average. At corporate events, rarely. Do not build tips into your pricing, treat them as upside.
