How This Calculator Works
Meal prep saves time and money, but only if you make the right amount. Cook too little and you are scrambling for meals midweek. Cook too much and you waste food. This calculator takes the guesswork out by computing exactly how many batches of a recipe you need.
The math is straightforward: multiply the number of people by the number of meals per week to get total servings needed, then divide by the recipe yield to find how many batches to cook. Since you cannot cook a fraction of a batch, the calculator rounds up and shows you the leftover servings.
Leftovers from meal prep are a feature, not a bug. Freeze extra portions in individual containers for busy days when you do not have time to cook or prep. Over a few weeks of meal prepping, you will build a freezer stockpile that acts as your personal ready-made meal collection.
Frequently Asked Questions
How long do meal prep containers last in the fridge?
Most prepped meals last 3-5 days in the refrigerator when stored properly in airtight containers. For meals beyond day 4, freeze them and thaw the night before. Rice-based dishes and soups tend to keep longer than dishes with raw vegetables.
What should I do with leftover servings?
Freeze them in individual portions for future quick meals. This builds a freezer stockpile over time so you always have backup meals available. Label containers with the dish name and date.
How do I scale a recipe for meal prep?
Multiply all ingredients by the number of batches the calculator recommends. For a recipe that serves 6 and you need 2 batches, double every ingredient. Season to taste after scaling — spices and salt do not always scale linearly.
