Drinks are the least-examined part of a Subway order and one of the easiest places to waste both money and calories. A large fountain soda can add more sugar than a cookie and more cost than doubling your meat. Here is what is actually available and what it costs.
Fountain drinks
Most US Subway restaurants pour Coca-Cola products; a minority carry Pepsi, and supermarket and campus locations sometimes have no fountain at all. Typical sizes are 21 oz small, 30 oz medium and 40 oz large, though cup sizes vary by franchise.
| Size | Typical price | Regular cola calories | Sugar |
|---|---|---|---|
| Small (~21 oz) | $2.19–$2.99 | ~210 | ~58 g |
| Medium (~30 oz) | $2.59–$3.39 | ~300 | ~83 g |
| Large (~40 oz) | $2.89–$3.79 | ~400 | ~110 g |
| Any size, diet or zero-sugar | Same | 0–5 | 0 g |
Free refills are a franchise decision, not a chain policy — common at freestanding stores, rare inside supermarkets and never at airports.
Bottled and canned
- Bottled water — usually $1.99–$2.79, and often cheaper than a fountain drink.
- Vitamin-style waters and sports drinks — $2.49–$3.49; check the sugar, many are 30 g+.
- Bottled sodas and iced teas — $2.29–$3.29.
- Juice and milk — small cartons at most stores, standard in a kids meal.
- Energy drinks — stocked at some travel-plaza and highway locations.
Coffee and tea
Hot coffee, decaf and hot tea are available all day at stores that serve breakfast, and frequently only in the morning elsewhere. Expect $1.79–$2.59 for a regular coffee — one of the better cheap coffees in fast food, and free or discounted with a breakfast combo at many locations. Freshly brewed unsweetened iced tea is standard on the fountain; sweet tea is regional, mostly the South, and carries roughly 130 calories per medium.
Does the combo deal save money?
Adding chips and a drink to a sub usually costs $3.50–$5.00, against $4.50–$6.00 buying them separately — so yes, typically a $1–$2 saving. But the cheapest genuinely good move is a Footlong plus tap or bottled water: you keep 300 calories and pay less than the combo. App offers frequently bundle drinks too; the mechanics are in our coupons guide and MVP Rewards guide.
Frequently asked
Does Subway have free water?
Most stores will give you a cup of tap water on request; policies vary by franchise.
Does Subway sell milkshakes or slushies?
Not as a chain-wide item. Some locations inside convenience stores and travel plazas have frozen drinks from the host site, not from Subway.
Can I order drinks in the app?
Yes, including fountain drinks, which you collect and pour yourself — see our online ordering guide.
Prices, cup sizes and beverage brands are set by individual franchisees and vary by location. Calorie figures are approximate for standard fills without ice adjustments.
