How to Use the Sushi & Sashimi Calorie Calculator
Sushi and sashimi have a light, healthy reputation, but calories add up quickly once you count how many pieces and ounces you actually ate. This calculator adds up nigiri sushi pieces, roll (maki) pieces, and sashimi weight in ounces to give you the total calories in one go.
Nigiri sushi — rice topped with fish — averages about 50 kcal per piece, and standard rolls run about 45 kcal per piece. Sushi topped with fattier fish like tuna belly or salmon can run a bit higher, and specialty rolls with mayo-based sauces or tempura fillings add even more than a standard roll. Sashimi, which skips the rice entirely, averages about 130 kcal per 100g (roughly 3.5 oz), making it lower calorie than sushi of the same weight.
Use this whenever you want to check the damage after an all-you-can-eat sushi outing, an omakase dinner, or a takeout sushi platter — just enter however many nigiri and rolls you had, plus any sashimi by weight, and mix and match as needed.
Actual calories can vary depending on the cut of fish and sauces used, so treat this as a solid estimate rather than an exact figure. The FAQ below breaks down the calorie differences between sushi types in more detail.
