Diet Pepsi

What Taco Bell says it is

On its product page Taco Bell describes it as “A crisp tasting, refreshing pop of sweet, fizzy bubbles without sugar, calories or carbs.”

The two calorie figures

No calories is the figure on both the listing and the nutrition record for Diet Pepsi.

The nutrition menu carries three sizes under this name: 16 fl oz at no calories, 20 fl oz at no calories and 30 fl oz at no calories; the picker above the ticket switches the panel between them. Two notes from the nutrition guide apply to every fountain drink: “Nutrition values for fountain beverages do not account for ice.” “Depending on the sodium content of the water where the beverage is dispensed, the actual sodium content may be higher or lower than the listed values.”

Where it was listed

Diet Pepsi was listed at 445 of the 452 restaurants read, in 50 states and DC on 19 September 2026. That makes it a core item: on nine in ten of the restaurant menus read or more.

Ohio had the lowest state median, $2.69; Alaska the highest, $3.49. A state median stands on ten restaurants at most, so a single expensive or cheap restaurant moves it; the national range is the safer figure. Pick a state on the board or on the prices by state page and the ticket on every page prices its lines at that state’s medians beside the national range.

What the price buys

By median price Diet Pepsi ranks 23rd of 35 in Drinks. The section median is $2.99, so it is $0.20 above it.

Taco Bell’s Happier Hour page says: “Get any Regular Freeze or Medium Fountain Drink for just $1 during Happier Hour, every day from 2 to 5 PM at participating locations.” That window is a time-of-day price, not the list price, and it is stated by the brand rather than read from a menu, so it sits in this sentence and not in the range above.

The record against a day

Diet Pepsi carries no calories on its record and 75 mg of sodium.

Allergens and certification

Taco Bell publishes no allergen statement for Diet Pepsi: it is not in the allergen tool and its record carries no allergen table. This site never marks an item free of anything without a statement, so it sits out of every allergen filter here. The guide’s general note still applies to it: “Peanuts, tree nuts, fish, and shellfish are not used in regular menu items served in Taco Bell restaurants.”

Ways to change it

One add-on is offered; the heaviest is Make it Dirty at no calories. The removable components and what each carries: Ice (no calories). Size prices were read at five restaurants for this page: Small $2.59 to $3.19, Medium $2.99 to $3.29 and Large $3.19 to $3.39. The line’s own range above stands on 445.

The option calories are the ordering menu’s own figures for the option, printed as it prints them; a swapped build is not a nutrition record, so the panel on this page stays the item as published. Option prices were read at five of the restaurants and are printed with that count, never as a national figure.

Next to it on the board

Next to it on the board: Lipton Unsweetened Iced Tea has the same calories and $0.40 less at the median; Diet Dr Pepper has the same calories and $0.10 more at the median; Mtn Dew Zero has the same calories and $0.40 less at the median.
