Fountain Soda or Cans: Which Keeps Your Mrgins Afloat
3 minute read
Fountain soda or cans: which one keeps your margins afloat? You spent three weeks perfecting the burger.
Then the delivery driver showed up and the soda was wearing it.
Soda looks like the smallest decision in your restaurant, right up until you add up the margins, the ice, the refills, the equipment, and the bag of fries swimming in Sprite.
Clients ask me all the time whether I'd go with a fountain or cans. I always start with three questions: How many drinks do you sell? Where are guests drinking them? What kind of service are you promising?
The ice factor nobody talks about
The size printed on the cup isn't what you're pouring. Most fountain cups end up about 30% ice, and drive-thru cups often run 40% or more.
So a 16-oz cup holds about 11 oz of soda, which is less than a 12-oz can.
Here's what each drink really costs at 30% ice. That includes syrup, carbonated water, the cup, lid, straw, ice, CO₂, and waste:
12-oz cup: 8.4 oz of soda · $0.39 · 4.6¢ per oz16-oz cup: 11.2 oz of soda · $0.51 · 4.6¢ per oz24-oz cup: 16.8 oz of soda · $0.73 · 4.3¢ per oz12-oz can: 12 oz of soda · $0.75 · 6.3¢ per oz
This is an illustrative scenario: $100 per 5-gallon syrup box at a 5:1 mix, and $18 per 24-can case. Equipment, labor, and refrigeration aren't included. Use your own invoices.
At 100 drinks a day, the 24-cent gap between a 16-oz fountain drink and a can adds up to about $720 a month. At 20 drinks a day, it's $144, and your fountain service contract might eat that before lunch.
One more thing: pay list price for your syrup instead of distributor pricing, and the 16-oz fountain drink ends up costing more than the can. Your syrup contract decides the whole debate.
Fountain: great margins, if you manage them
The upside: Upselling is where the money is. Going from a 16-oz to a 24-oz cup costs you about 22 cents. Charge a dollar more and most of it is profit. "Make it a large?" is the most profitable sentence in fast casual.
The downside: Cleaning, calibration, CO₂, filters, repairs, and supplier contracts full of minimums and exclusivity clauses. Also, "free refills" describes the guest's bill, not yours. Every 16-oz refill costs you about 29 cents.
Cans: delivery's best friend
Cans are sealed, consistent, and spill-proof, and there's no melting ice watering down the drink on the way to someone's door.
That matters, because according to the National Restaurant Association, nearly 75% of restaurant traffic is now off-premises, and 65% of limited-service operators offer delivery. If your drinks leave the building, they have to survive the trip.
The trade-offs: a higher cost per ounce, constant restocking, and no upsizing. A can is a can. Quick side note: cans have a way of disappearing into aprons, backpacks, and "just one for the train," so count them in your weekly inventory and give your team a clear staff-drink policy, because nobody slips a fountain cup into their coat pocket.
Don't forget the square footage
A fountain needs counter space, a syrup rack, a CO₂ tank, a carbonator, drainage, and enough ice to keep up. Cans need cooler space and dry storage.
In New York, every square foot has a rent check attached. Ask what else could earn money in that space. A grab-and-go cooler might beat a six-head fountain that sits idle at 3 p.m.
My verdict
Busy casual restaurant: Fountain in-house and cans for delivery, if your volume supports both.
Small or delivery-heavy operation: Start with cans. Add a fountain when the numbers say so, not when the sales rep does.
Polished dining room: Serve it in a proper glass with a thoughtful pour, and count the glassware and dishwashing in your cost.
Whatever you choose, track three numbers: drinks per 100 orders, average beverage revenue per check, and profit after costs. Refills are consumption, not sales.
FAQ
How much soda is in a 16-oz cup with ice?
About 11 oz with a normal amount of ice (around 30%), and closer to 9.6 oz with heavy ice.
Is fountain soda cheaper than cans for restaurants?
Usually, per ounce, at good distributor pricing and steady volume. At low volume or list-price syrup, cans can come out ahead.
Should I serve fountain drinks or cans for delivery?
Cans. They're sealed, they don't spill, and they don't get watered down on the way.
Let's find the money in your beverage program
Drinks are among the highest-margin items on your menu, and among the least managed.
I've worked every side of this business: I helped grow DIG from 1 to 17 locations, and ran operations across 12 concepts and about $90M in revenue at Fireman Hospitality Group. I look at purchasing, sales mix, space, and service together, because a soda decision is really a profit decision. 30 minutes with your invoices, and you'll leave knowing your real cost per drink and the setup that earns its space.
Your soda should have bubbles. Your business case shouldn't.
