How to Use the Gimbap Ingredient Cost Calculator
If you make gimbap for lunch boxes often, you may wonder exactly how much a single roll actually costs in ingredients. This calculator takes the prices of nori, rice, other fillings (pickled radish, egg, carrot, ham), and seasoning, then instantly calculates the cost per roll and the total for however many rolls you're making.
Nori cost is calculated by dividing the 10-sheet pack price by 10 for the per-sheet cost, and rice uses 22% of the per-lb price (about the amount of rice in one roll). Add in the other fillings and the sesame oil/seasoning cost, and you get the total cost per roll.
This figure reflects raw ingredient cost only — it doesn't include your prep time and effort or any packaging costs. Comparing it to what a pre-made roll costs at a grocery store or gimbap shop is a handy way to see how much you're actually saving by making it yourself, which is useful when planning lunch boxes for the week.

No, this calculator only covers raw ingredient cost. It doesn't account for your time and effort, or the labor cost built into store-bought gimbap.
