School Lunch Nutrition Calculator. Build a nutritionally balanced school lunch by entering your food items, serving sizes, and meal components. The School Lunch Nutrition Calculator totals your calories, protein, carbohydrates, fat, and sodium, then checks your meal against USDA Smart Snacks and school nutrition guidelines so you can plan lunches kids will eat and schools will approve. Also try the Food Waste Calculator.
Smart Snacks in School are nutrition standards set by the USDA that apply to all foods and beverages sold on a school campus during the school day — excluding reimbursable meals. They require limits on calories, saturated fat, sodium, and added sugars, and encourage whole grains and fruit/vegetable components. The rules apply from midnight before the school day until 30 minutes after the end of the official school day. See also our Safety Status — Leftovers Shelf Life.
USDA calorie targets differ by grade: Grades K–5 should receive 550–650 kcal, Grades 6–8 should receive 600–700 kcal, and Grades 9–12 should receive 750–850 kcal per lunch. This calculator checks your entered calorie total against the appropriate range for your selected grade group.
Current USDA sodium targets (Sodium Target 1) set limits of 1,230 mg for K–5, 1,360 mg for 6–8, and 1,420 mg for 9–12 per school lunch. Future targets continue to reduce these levels. Staying within the limit is one of the factors scored in this calculator.
A food item is considered whole-grain rich when at least 50% of its grain ingredients are whole grain by weight, and the item contains at least 8 grams of whole grain per serving. USDA requires that at least half the weekly grain servings offered in school meal programs be whole-grain rich.
For Smart Snacks, saturated fat must be less than 10% of the item's total calories. For example, a 200-calorie item may contain no more than 2.2 g of saturated fat (200 × 0.10 ÷ 9 kcal/g). This calculator computes saturated fat as a percentage of your total calories and flags it if it exceeds the 10% threshold.
Yes — USDA reimbursable school lunches must offer low-fat (1%) unflavored or fat-free (flavored or unflavored) milk as a required meal component. Students may decline it, but it must be offered. The calculator includes a milk component check as part of the overall compliance score.
USDA requires schools to offer at least ½ cup of fruit and/or vegetables per lunch service. Students must take at least ½ cup of fruit or vegetable as part of a reimbursable meal. The calculator checks whether the combined cups entered meet this minimum requirement.
In most states, yes — all food and beverage fundraisers conducted on school campuses during the school day must meet Smart Snacks standards. Some states previously allowed exemptions, but many (including Washington State) have eliminated them, meaning every item sold must comply regardless of the fundraising purpose.
